Mazda Logo2021 Mazda3 ABS and Power Steering User Manual

Introduction

A compact automobile with a blend of style, performance, and cutting-edge technologies is the 2021 Mazda3. The Mazda3’s Anti-lock Braking System (ABS) is one of the most important safety elements because it improves the vehicle’s braking effectiveness. The 2021 Mazda3’s ABS is meant to stop the wheels from locking up under severe or abrupt braking. It keeps track of each wheel’s rotational speed via a network of sensors. The technology regulates the brake pressure to a specific wheel or wheels when it notices that one or more wheels are ready to lock up, allowing the driver to maintain control and steering ability while braking. Due to this technology, the Mazda3 is far less likely to skid and has better overall stopping power, making it safer to operate in emergency brake situations or on slick roads.

The Mazda3 of 2021 features both an effective and quick power steering system in addition to the ABS. The Mazda3’s power steering system makes use of an electric motor to help the driver easily move the car. According to the vehicle’s speed, this technology modifies the level of assistance, offering more help at low speeds for simple parking and maneuvering and less help at higher speeds for a more connected and direct driving experience.

ABS and Power Steering

Brake System

Foot Brake
This vehicle has power-assisted brakes that adjust automatically through normal use. Should power-assist fail, you can stop by applying greater force than normal to the brake pedal. But the distance required to stop will be greater than usual.

WARNING
Do not coast with the engine stalled or turned off, find a safe place to stop:
Coasting with the engine stalled or turned off is dangerous. Braking will require more effort, and the brake’s power-assist could be depleted if you pump the brake. This will cause longer stopping distances or even an accident.

Shift to a lower gear when going down steep hills:
Driving with your foot continuously on the brake pedal or steadily applying the brakes for long distances is dangerous. This causes overheated brakes, resulting in longer stopping distances or even total brake failure. This could cause loss of vehicle control and a serious accident. Avoid continuous application of the brakes.

Dry off brakes that have become wet by driving slowly, releasing the accelerator pedal and lightly applying the brakes several times until the brake performance returns to normal:
Driving with wet brakes is dangerous. Increased stopping distance or the vehicle pulling to one side when braking could result in a serious accident. Light braking will indicate whether the brakes have been affected.

CAUTION

  • Do not drive with your foot held on the clutch pedal or brake pedal, or hold the clutch pedal depressed halfway unnecessarily. Doing so could result in the following:
  • The clutch and brake parts will wear out more quickly.
  • The brakes can overheat and adversely affect brake performance.
  • Always depress the brake pedal with the right foot. Applying the brakes with the unaccustomed left foot could slow your reaction time to an emergency situation resulting in insufficient braking operation.

Warning Light
The warning light turns on when the system has a malfunction. Refer to Brake System Warning Indication/Warning Light.

Brake Pad Wear Indicator
When the disc brake pads become worn, the built-in wear indicators contact the disc plates. This causes a screeching noise to warn that the pads should be replaced.2021 Mazda3 ABS and Power Steering User Manual-04

When you hear this noise, consult an Authorized Mazda Dealer as soon as possible.

WARNING
Do not drive with worn disc pads: Driving with worn disc pads is dangerous. The brakes could fail and cause a serious accident. As soon as you hear a screeching noise consult an Authorized Mazda Dealer.

NOTE
In high humidity weather conditions, brake noises, such as brake squeak or brake squeal can be heard. It does not indicate a malfunction.

Brake Assist
During emergency braking situations when it is necessary to depress the brake pedal with greater force, the brake assist system provides braking assistance, thus enhancing braking performance. When the brake pedal is depressed hard or depressed more quickly, the brakes apply more firmly.

NOTE

  • When the brake pedal is depressed hard or depressed more quickly, the pedal will feel softer but the brakes will apply more firmly. This is a normal effect of the brake assist operation and does not indicate a malfunction.
  • When the brake pedal is depressed hard or depressed more quickly, a motor/pump operation noise may be heard. This is a normal effect of the brake assist and does not indicate a malfunction.
  • The brake assist equipment does not supersede the functionality of the vehicle’s main braking system.

Brake Override System
The brake override system applies the brake first for safety if the brake pedal and accelerator pedal are depressed at the same time.

NOTE
Operation of the brake override system can be turned on or off. Refer to the Settings section in the Mazda Connect Owner’s Manual.

AUTOHOLD
The AUTOHOLD function automatically holds the vehicle stopped, even if you take your foot off the brake pedal. This function can be best used while stopped in traffic or at a traffic light. The brakes are released when you start driving the vehicle.

WARNING

Do not rely completely on the AUTOHOLD function:
The AUTOHOLD function is only designed to assist the brake operation while the vehicle is stopped. Neglecting to operate the brakes and relying only on the AUTOHOLD system is dangerous and could result in an unexpected accident if the vehicle were to suddenly move. Operate the brakes appropriately in accordance with the road and surrounding conditions.

Do not release your foot from the brake pedal while the vehicle is stopped on a steep grade:
Because there is a possibility of the vehicle not being held in the stopped position by the AUTOHOLD function, the vehicle may move unexpectedly and result in an accident.

Do not use the AUTOHOLD function on slippery roads such as icy or snow-covered roads, or unpaved roads:
Even if the vehicle is held in the stopped position by the AUTOHOLD function, the vehicle may move unexpectedly and result in an accident. Operate the accelerator pedal, brakes, or steering wheel appropriately as necessary.

Immediately depress the brake pedal in the following cases:
Because the AUTOHOLD function is canceled forcibly, the vehicle may move unexpectedly and result in an accident.

  • “Depress Brake Pedal. Brake Hold Disabled” is displayed in the multi-information display and the warning sound is activated at the same time.

Always apply the parking brake when parking the vehicle:
Not applying the parking brake when parking the vehicle is dangerous as the vehicle may move unexpectedly and result in an accident. When parking the vehicle, shift the selector lever to the P position (automatic transmission vehicle) and apply the parking brake.

CAUTION
If you stop operating the accelerator pedal before the vehicle starts moving, the force holding the vehicle in the stopped position may weaken. Firmly depress the brake pedal or depress the accelerator pedal to accelerate the vehicle.

NOTE

    The ignition is switched OFF.
    There is a problem with the AUTOHOLD function.

Hill Launch Assist (HLA)

The HLA functions to assist in accelerating the vehicle from a stop on slopes. When releasing the brake pedal and depressing the accelerator pedal to accelerate the vehicle from a stop while on a slope, the function prevents the vehicle from rolling. The HLA also operates when reversing on a slope. The braking force is maintained automatically after releasing the brake pedal on a steep slope. For manual transmission vehicles, the HLA operates when the vehicle is tilted rearward with the shift lever in a forward gear, and operates when the vehicle is tilted forward with the shift lever in the R position. For automatic transmission vehicles, the HLA operates when the vehicle is tilted rearward with the selector lever in a forward gear, and operates when the vehicle is tilted forward with the selector lever in the R position.

WARNING

Do not rely completely on HLA:
HLA is an auxiliary device for accelerating from a stop on a slope. The system only operates for about 2 seconds and therefore, relying only on the system, when accelerating from a stop is dangerous because the vehicle may move (roll) unexpectedly and cause an accident. The vehicle could roll depending on the vehicle’s load or if it is towing something. In addition, for vehicles with a manual transmission, the vehicle could still roll depending on how the clutch pedal or the accelerator pedal is operated.

Always confirm the safety around the vehicle before starting to drive the vehicle.

NOTE

  • HLA does not operate on a gentle slope. In addition, the gradient of the slope on which the system will operate changes depending on the vehicle’s load.
    HLA does not operate if the parking brake is applied, the vehicle has not stopped completely, or the clutch pedal is released.
    While HLA is operating, the brake pedal may feel stiff and vibrate, however, this does not indicate a malfunction.
    HLA does not operate while the TCS/DSC indicator light is illuminated.
    Refer to TCS/DSC Indication/Indicator Light (Turns on)
  • HLA does not turn off even if the DSC OFF switch is pressed to turn off the TCS/DSC.

Antilock Brake System (ABS)

The ABS control unit continuously monitors the speed of each wheel. If one wheel is about to lock up, the ABS responds by automatically releasing and reapplying that wheel’s brake.
The driver will feel a slight vibration in the brake pedal and may hear a chattering noise from the brake system. This is normal ABS system operation. Continue to depress the brake pedal without pumping the brakes. The warning light turns on when the system has a malfunction. Refer to ABS Warning Indication/Warning Light.

WARNING
Do not rely on ABS as a substitute for safe driving:
The ABS cannot compensate for unsafe and reckless driving, excessive speed, tailgating (following another vehicle too closely), driving on ice and snow, and hydroplaning (reduced tire friction and road contact because of water on the road surface). You can still have an accident.

NOTE

  • Braking distances may be longer on loose surfaces (snow or gravel, for example) which usually have a hard foundation. A vehicle with a normal braking system may require less distance to stop under these conditions because the tires will build up a wedge of surface layer when the wheels skid.
  • The sound of the ABS operating may be heard when starting the engine or immediately after starting the vehicle, however, it does not indicate a malfunction.

Traction Control System (TCS)

The Traction Control System (TCS) enhances traction and safety by controlling engine torque and braking. When the TCS detects driving wheel slippage, it lowers engine torque and operates the brakes to prevent loss of traction. This means that on a slick surface, the engine adjusts automatically to provide optimum power to the drive wheels, limiting wheel spin and loss of traction.
The warning light turns on when the system has a malfunction. Refer to TCS/DSC Indication/Indicator Light (Turns on).

WARNING
Do not rely on the Traction Control System (TCS) as a substitute for safe driving:
The Traction Control System (TCS) cannot compensate for unsafe and reckless driving, excessive speed, tailgating (following another vehicle too closely), and hydroplaning (reduced tire friction and road contact because of water on the road surface). You can still have an accident.

Use snow tires or tire chains and drive at reduced speeds when roads are covered with ice and/or snow:
Driving without proper traction devices on snow and/or ice-covered roads is dangerous. The Traction Control System (TCS) alone cannot provide adequate traction and you could still have an accident.

NOTE
To turn off the TCS, press the DSC OFF switch.

TCS/DSC Indicator Light2021 Mazda3 ABS and Power Steering User Manual-11

This indicator light stays on for a few seconds when the ignition is switched ON. If the TCS or DSC is operating, the indicator light flashes. If the light stays on, the TCS, DSC or the brake assist system may have a malfunction and they may not operate correctly. Take your vehicle to an Authorized Mazda Dealer.

NOTE

  • In addition to the indicator light flashing, a slight lugging sound will come from the engine. This indicates that the TCS/DSC is operating properly.
    On slippery surfaces, such as fresh snow, it will be impossible to achieve high rpm when the TCS is on.

Dynamic Stability Control (DSC)

The Dynamic Stability Control (DSC) automatically controls braking and engine torque in conjunction with systems such as ABS and TCS to help control side slip when driving on slippery surfaces, or during sudden or evasive maneuvering, enhancing vehicle safety.

Refer to ABS and TCS
DSC operation is possible at speeds greater than 20 km/h (12 mph). The warning light turns on when the system has a malfunction. Refer to TCS/DSC Indication/Indicator.

WARNING
Do not rely on the Dynamic Stability Control as a substitute for safe driving:

The Dynamic Stability Control (DSC) cannot compensate for unsafe and reckless driving, excessive speed, tailgating (following another vehicle too closely), and hydroplaning (reduced tire friction and road contact because of water on the road surface). You can still have an accident.

CAUTION

  • The DSC may not operate correctly unless the following are observed:
  • Use tires of the correct size specified for your Mazda on all 4 wheels.
  • Use tires of the same manufacturer, brand and tread pattern on all 4 wheels.
  • Do not mix worn tires.
  • The DSC may not operate correctly when tire chains are used or a temporary spare tire is installed because the tire diameter changes.

NOTE
If there is a problem with the DSC, the Hill Launch Assist (HLA) may not operate. Refer to Hill Launch Assist (HLA).

TCS/DSC Indicator Light2021 Mazda3 ABS and Power Steering User Manual-11

This indicator light stays on for a few seconds when the ignition is switched ON. If the TCS or DSC is operating, the indicator light flashes. If the light stays on, the TCS, DSC or the brake assist system may have a malfunction and they may not operate correctly. Take your vehicle to an Authorized Mazda Dealer.

DSC OFF Indicator Light
This indicator light stays on for a few seconds when the ignition is switched ON. It also illuminates when the DSC OFF switch is pressed and TCS/DSC is switched off. Refer to DSC OFF Switch. If the light remains illuminated and the TCS/DSC is not switched off, take your vehicle to an Authorized Mazda Dealer. The DSC may have a malfunction.

DSC OFF Switch
Press the DSC OFF switch to turn off the TCS/DSC. The DSC OFF indicator light in the instrument cluster will illuminate.2021 Mazda3 ABS and Power Steering User Manual-13Press the switch again to turn the TCS/DSC back on. The DSC OFF indicator light will turn off.

NOTE

  • When DSC is on and you attempt to free the vehicle when it is stuck, or drive it out of freshly fallen snow, the TCS (part of the DSC system) will activate. Depressing the accelerator will not increase engine power and freeing the vehicle may be difficult. When this happens, turn off the TCS/DSC.
  • If the TCS/DSC is off when the engine is turned off, it automatically activates when the ignition is switched ON.
  • Leaving the TCS/DSC on will provide the best traction.
  • If the DSC OFF switch is pressed and held for 10 seconds or more, the DSC OFF switch malfunction detection function operates and the DSC system activates automatically. The DSC OFF indicator light turns off while the DSC system is operative.
    (Vehicles with Smart Brake Support (SBS))
    If the Smart Brake Support (SBS) operates with the TCS/DSC turned off, the TCS/DSC becomes operational automatically.

Drive Selection

Drive selection is a system to switch the vehicle’s drive mode. When the sport mode is selected, vehicle’s response against accelerator operation is enhanced. This provides additional quick acceleration which may be needed to safely make maneuvers such as lane changes, merging onto freeways, or passing other vehicles.

Distance & Speed Alert (DSA)

The DSA is a system which provides advice for maintaining the appropriate distance between vehicles and notifies the driver of the recommended, safe distance to maintain with a vehicle ahead. The system measures the distance between your vehicle and a vehicle ahead while the vehicle speed is about 30 km/h (19 mph) or faster. If the distance between your vehicle and a vehicle ahead is close, the system alerts the driver of a possible collision using an indication on the display.

WARNING

Do not rely completely on the DSA:
The ability of the system to detect a vehicle ahead is limited depending on the type of vehicle ahead, weather conditions, or traffic conditions. In addition, the system is not for maintaining the distance between your vehicle and a vehicle ahead. If you neglect to operate the accelerator and brake pedals correctly, it could lead to an accident. Always check the safety of the surrounding area and depress the brake pedal or accelerator pedal while keeping a safe distance from vehicles ahead or on-coming vehicles.
