Braking System

Power Brakes

Your vehicle has power-assisted brakes that adjust automatically through normal usage. In the event of a vehicle power failure, the power assist for the brakes will not work. You can still stop your vehicle, but it will require greater force and increased pedal travel than normal. The stopping distance, however, will be longer than with power brakes.

Information

• When the brake pedal is depressed under certain driving conditions
  or weather conditions, you may temporarily hear a noise. This is normal and does not indicate a problem with your brakes.
• While driving on a road with deicing chemicals, brake noise or abnormal tire wear may occur due to deicing chemicals. In safe traffic conditions, additionally, apply the brakes to remove deicing chemicals on the brake discs and pads.

WARNING

• Take the following precautions:
  Do not drive with your foot resting on the brake pedal. This will create abnormally high brake temperatures, excessive brake lining and pad wear, and increased stopping distances.
• When descending a long or steep hill, shift to a lower gear and avoid continuous application of the brakes. Applying the brakes continuously will cause the brakes to overheat and could result in a temporary loss of braking performance.
• Wet brakes may impair the vehicle’s ability to safely slow down; the vehicle may also pull to one side when the brakes are applied. Applying the brakes lightly will indicate whether they have been affected in this way. Always test your brakes in this fashion after driving through deep water. To dry the brakes, lightly tap the brake pedal to heat up the brakes while maintaining a safe forward speed until brake performance returns to normal. Avoid driving at high speeds until the brakes function correctly.

NOTICE

• Do not continue depressing the brake pedal if the ” ” indicator is OFF. The battery may be discharged.
• Noise and vibration generated during braking is normal.
• Under normal operation, electric brake pump noise and motor vibration may occur temporarily in the below cases.
  • When the pedal is depressed suddenly.
  • When the pedal is repeatedly depressed in short intervals.
  • When the ABS function is activated while braking.

Disc Brakes Wear Indicator
When your brake pads are worn and new pads are required, you will hear a high-pitched warning sound from your front or rear brakes. You may hear this sound come and go or it may occur whenever you depress the brake pedal.

NOTICE
To avoid costly brake repairs, do not continue to drive with worn brake pads.

Information
Always replace brake pads as complete front or rear axle sets.

Anti-lock Brake System (ABS)

WARNING
Anti-Lock Braking System (ABS) or Electronic Stability Control (ESC) will not prevent accidents due to improper or dangerous driving manoeuvres. Even though vehicle control is improved during emergency braking, always maintain a safe distance between you and objects ahead of you. Vehicle speeds should always be reduced during extreme road conditions. The braking distance for vehicles equipped with ABS or ESC may be longer than for those without these systems in the following road conditions.

Drive your vehicle at reduced speeds during the following conditions:

• Rough, gravel or snow-covered roads.
• On roads where the road surface is pitted or has a different surface height.
• Tire chains are installed on your vehicle. Drive your vehicle at reduced speeds during the above conditions.

The safety features of ABS or ESC-equipped vehicle should not be tested by high-speed driving or cornering. This could endanger the safety of yourself or others.

ABS is an electronic braking system that helps to prevent a braking skid. ABS allows the driver to steer and brake at the same time.

Using ABS
To obtain the maximum benefit from your ABS in an emergency situation, do not attempt to modulate your brake pressure and do not try to pump your brakes. Depress your brake pedal as hard as possible. When you apply your brakes under conditions that may lock the wheels, you may hear sounds from the brakes, or feel a corresponding sensation in the brake pedal. This is normal and it means your ABS is active.
ABS does not reduce the time or distance it takes to stop the vehicle. Always maintain a safe distance from the vehicle in front of you. ABS will not prevent a skid that results from sudden changes in direction, such as trying to take a corner too fast or making a sudden lane change. Always drive at a safe speed depending on the road and weather conditions.
ABS cannot prevent a loss of stability. Always steer moderately when braking hard. Severe or sharp steering wheel movement can still cause your vehicle to veer into oncoming traffic or off the road.
On loose or uneven road surfaces, the operation of the anti-lock brake system may result in a longer stopping distance than for vehicles equipped with a conventional brake system.
The ABS warning light will stay on for several seconds after the START/STOP button is placed in the ON position. During that time, the ABS will go through self-diagnosis and the light will go off if everything is normal. If the light stays on, you may have a problem with your ABS. Contact an authorized HYUNDAI dealer as soon as possible.

WARNING
If the ABS warning light is on and stays on, you may have a problem with the ABS. Your power brakes will work normally. To reduce the risk of serious injury or death, contact your HYUNDAI dealer as soon as possible.

NOTICE
When you drive on a road having poor traction, such as an icy road, and apply your brakes continuously, ABS will be active continuously and the ABS warning light may illuminate.
Pull your vehicle over to a safe place and turn the vehicle off.
Restart the vehicle. If the ABS warning light is off, then your ABS system is normal.
Otherwise, you may have a problem with your ABS system. Contact an authorized HYUNDAI dealer as soon as possible.

Information
When you jump-start your vehicle because of a drained battery, the ABS warning light ( ) may turn on at the same time. This happens because of the low battery voltage. It does not mean your ABS is malfunctioning. Has the battery recharged before driving the vehicle?

Electronic Stability Control (ESC)

The Electronic Stability Control (ESC) system helps to stabilize the vehicle during cornering manoeuvres.
ESC checks where you are steering and where the vehicle is actually going. ESC applies braking pressure to any one of the vehicle’s brakes and intervenes in the electric vehicle control system to assist the driver with keeping the vehicle on the intended path. It is not a substitute for safe driving practices. Always adjust your speed and driving to the road conditions.

WARNING
Never drive too fast for the road conditions or too quickly when cornering. The ESC system will not prevent accidents.
Excessive speed in turns, abrupt manoeuvres, and hydroplaning on wet surfaces can result in severe accidents.

ESC operation
ESC ON condition
When the START/STOP button is in the ON position, ESC and the ESC OFF indicator lights illuminate for approximately three seconds and goes off, then ESC is turned on.

When operating
When ESC is in operation, the ESC indicator light blinks:

• When you apply your brakes under conditions which may lock the wheels, you may hear sounds from the brakes, or feel a corresponding sensation in the brake pedal. This is normal and it means your ESC is active.
• When ESC activates, the vehicle may not respond to the accelerator as it does under routine conditions.
• If Cruise Control was in use when ESC activates, Cruise Control automatically disengages. Cruise Control can be reengaged when the road conditions allow. See “Cruise Control System” later in this chapter 7. (if equipped)

ESC OFF condition
To cancel ESC operation:

• State 1

Press the ESC OFF button briefly. The ESC OFF indicator light and message “Traction Control disabled” will illuminate. In this state, the traction control function of ESC is disabled, but the brake control function of ESC (braking management) still operates.

State 2

Press and hold the ESC OFF button continuously for more than 3 seconds. The ESC OFF indicator light and message “Traction & Stability Control disabled” illuminates and a warning chime sounds. In this state, both the traction control function of ESC and the brake control function of ESC are disabled.
If the START/STOP button is placed in the LOCK/OFF position when ESC is off, ESC remains off. Upon restarting the vehicle, the ESC will automatically turn on again.

Indicator lights  When the START/STOP button is in the ON position, the ESC indicator light illuminates, then goes off if ESC is operating normally.
The ESC indicator light blinks whenever ESC is operating.
If the ESC indicator light stays on, your vehicle may have a malfunction with the ESC system. When this warning light illuminates, have the vehicle checked by an authorized HYUNDAI dealer as soon as possible.
The ESC OFF indicator light comes on when ESC is turned off with the button.

WARNING
When ESC is blinking, this indicates ESC is active:
Drive slowly and NEVER attempt to accelerate. NEVER turn ESC off while the ESC indicator light is blinking or you may lose control of the vehicle resulting in an accident.

NOTICE
Driving with wheels and tires with different sizes may cause ESC to malfunction. Before replacing tires, make sure all four tires and wheels are the same size. Never drive the vehicle with different sized wheels and tires installed.

ESC OFF usage
When Driving
The ESC OFF mode should only be used briefly to help free the vehicle if stuck in snow or mud, by temporarily stopping operation of ESC, to maintain wheel torque.
To turn ESC off while driving, press the ESC OFF button while driving on a flat road surface.

NOTICE

• Do not allow wheel(s) of one axle to  spin excessively while the ESC, ABS, and parking brake warning lights are displayed. The repairs would not be covered by the vehicle warranty. Reduce vehicle power and do not spin the wheel(s) excessively while these lights are displayed.
• When operating the vehicle on a dynamometer, make sure ESC is turned off (ESC OFF light illuminated).

Information
Turning ESC off does not affect ABS or standard brake system operation.

Vehicle Stability Management (VSM)

Vehicle Stability Management (VSM) is a function of the Electronic Stability Control (ESC). It helps ensure the vehicle stays stable when accelerating or braking suddenly on wet, slippery and rough roads where traction over the four tires can suddenly become uneven.

WARNING
Take the following precautions when using Vehicle Stability Management (VSM):

• ALWAYS check the speed and the distance to the vehicle ahead. VSM is not a substitute for safe driving practices.
• Never drive too fast for the road conditions. VSM will not prevent accidents. Excessive speed in bad weather, on slippery and uneven roads can result in severe accidents.

VSM operation
VSM ON condition
VSM operates when:

• Electronic Stability Control (ESC) is on.
• Vehicle speed is approximately under 93 mph (150 km/h) when the vehicle is braking on rough roads.

When operating
When you apply your brakes under conditions which may activate ESC, you may hear sounds from the brakes, or feel a corresponding sensation in the brake pedal. This is normal and it means your VSM is active.

Information
VSM does not operate when:

• Driving on a banked road such as gradient or incline.
• Driving in reverse.
• The ESC OFF indicator light is on.
• The EPS (Electric power steering) warning light ) is on or blinks.

WARNING
If the ESC indicator light ( ) or EPS warning light ( ) stays illuminated or blinks, your vehicle may have a malfunction with VSM. When the warning light illuminates, have the vehicle checked by an authorized HYUNDAI dealer as soon as possible.

NOTICE
Driving with wheels and tires with different sizes may cause VSM to malfunction. Before replacing tires, make sure all four tires and wheels are the same size. Never drive the vehicle with different-sized tires and wheels installed.

Hill-Start Assist Control (HAC)

Hill-Start Assist Control (HAC) helps prevent the vehicle from rolling backwards when starting a vehicle from a stop on a hill. The system operates the brakes automatically for approximately 3 seconds and releases the brake after 3 seconds or when the accelerator pedal is depressed.

WARNING
Always be ready to depress the accelerator pedal when starting off on an incline. The HAC activates only for approximately 5 seconds.

Information

• HAC does not operate when the shift lever is in P (Park) or N (Neutral).
• HAC activates even when ESC  (Electronic Stability Control) is off. However, it does not activate, when ESC does not operate normally.

Good Braking Practices

WARNING

Whenever leaving the vehicle or parking, always come to a complete stop and continue to depress the brake pedal. Move the shift lever into the P
(Park) position, then apply the parking brake, and place the START/STOP button in the LOCK/OFF position.
Vehicles parked with the parking brake not applied or not fully engaged may roll inadvertently and may cause injury to the driver and others. ALWAYS apply the parking brake before exiting the vehicle.

Wet brakes can be dangerous! The brakes may get wet if the vehicle is driven through standing water or if it
is washed. Your vehicle will not stop as quickly if the brakes are wet. Wet brakes may cause the vehicle to pull to one side.
To dry the brakes, apply the brakes lightly until the braking action returns to normal, taking care to keep the vehicle under control at all times. If
the braking action does not return to normal, stop as soon as it is safe to do so. Call an authorized HYUNDAI dealer for assistance.
DO NOT drive with your foot resting on the brake pedal. Even light, but constant pedal pressure can result in the brakes overheating, brake wear, and possibly even brake failure.
If a tire goes flat while you are driving, apply the brakes gently and keep the vehicle pointed straight ahead while you slow down. When you are moving slowly enough for it to be safe to do so, pull off the road and stop in a safe location.
Keep your foot firmly on the brake pedal when the vehicle is stopped to prevent the vehicle from rolling forward.
