Speedometer
The speedometer shows the vehicle speed in either kilometers per hour (km/h) or miles per hour (mph).
Odometer
The odometer shows how far the vehicle has been driven, in either kilometers or miles.
Trip Odometer
The trip odometer shows how far the vehicle has been driven since the trip odometer was last reset.
The trip odometer is accessed and reset through the Driver Information Center (DIC).
Tachometer
The tachometer displays the engine speed in revolutions per minute (rpm). For vehicles with the Stop/Start system, when the ignition is on, the tachometer indicates the vehicle status. When pointing to AUTO STOP, the engine is off but the vehicle is on and can move. The engine could auto-start at any time. When the indicator points to OFF, the vehicle is off.
When the engine is on, the tachometer will indicate the engine’s revolutions per minute (rpm). The tachometer may vary by several hundred rpm, during Auto Stop mode, when the engine is shutting off and restarting.
Fuel Gauge
When the ignition is on, the fuel gauge indicates how much fuel
is left in the tank.
There is an arrow near the fuel gauge pointing to the side of the vehicle the fuel door is on.
When the indicator is empty, the low fuel light comes on. There still is a little fuel left, but the vehicle should be refuelled soon.
Here are four things that some owners ask about. None of these show a problem with the fuel gauge:
- At the service station, the fuel pump shuts off before the gauge reads full.
- It takes a little more, or less fuel to fill up than the gauge indicated. For example, the gauge may have indicated the tank was half full, but it took a little more, or less than half the tank’s capacity to fill the tank.
- The gauge moves a little while turning a corner, speeding up, or braking.
- The gauge takes a few seconds to stabilize after the ignition is turned on and goes back to empty when the ignition is turned off
Engine Coolant Temperature Gauge
English
Metric
This gauge measures the temperature of the vehicle’s engine. While driving under normal operating conditions, if the red LED is illuminated, the engine is too hot. Pull off the road, stop the vehicle, and turn off the engine as soon as possible.

Seat Belt Reminders
Driver Seat Belt Reminder Light
There is a driver seat belt reminder light on the instrument cluster.
When the vehicle is started, this light flashes and a chime may come on to remind the driver to fasten their seat belt.
Then the light stays on solid until the belt is buckled. This cycle may continue several times if the driver remains or becomes unbuckled while the vehicle is moving.
If the driver seat belt is buckled, neither the light nor the chime comes on.
Front Passenger Seat Belt Reminder Light
The vehicle may have a front passenger seat belt reminder light near the passenger airbag status indicator.
When the vehicle is started, this light flashes and a chime may come on to remind passengers to fasten their seat belts.
Then the light stays on solid until the belt is buckled. This cycle continues several times if the front passenger remains or becomes unbuckled while the vehicle is moving.
If the front passenger seat belt is buckled, neither the chime nor the light comes on.
The front passenger seat belt reminder light and chime may come on if an object is put on the seat such as a briefcase, handbag, grocery bag, laptop, or other electronic device. To turn off the reminder light and/or chime, remove the object from the seat or buckle the seat belt.
Airbag Readiness Light
problem with the airbag system. It is located in the instrument cluster. The system check includes the airbag sensor(s), the passenger sensing system, the pretensioners, the airbag modules, the wiring, and the crash sensing and diagnostic module. 
The airbag readiness light comes on for several seconds when the vehicle is started. If the light does not come on then, have it fixed immediately.
Warning
If the airbag readiness light stays on after the vehicle is started or comes on while driving, it means the airbag system might not be working properly. The airbags in the vehicle might not inflate in a crash, or they could even inflate without a crash. To help avoid injury, have the vehicle serviced right away.
If there is a problem with the airbag system, a Driver Information Center (DIC) message may also come on.
Passenger Airbag Status Indicator
The vehicle has a passenger sensing system. See Passenger Sensing System 0 58 for important safety information. The overhead console has a passenger airbag status indicator.
When the vehicle is started, the passenger airbag status indicator will light ON and OFF, or the symbol for on and off, for several seconds as a system check. Then, after several more seconds, the status indicator will light either ON or OFF, or either the on or off symbol, to let you know the status of the front outboard passenger frontal airbag.
If the word ON, or the on symbol, is lit on the passenger airbag status indicator, it means that the front outboard passenger frontal airbag is allowed to inflate.
If the word OFF, or the off symbol, is lit on the passenger airbag status indicator, it means that the passenger sensing system has turned off the front outboard passenger frontal airbag.
If, after several seconds, both status indicator lights remain on, or if there are no lights at all, there may be a problem with the lights or the passenger sensing system. See your dealer for service.
Warning
If the airbag readiness light ever comes on and stays on, it means that something may be wrong with the airbag system. To help avoid injury to yourself or others, have the vehicle serviced right away. See Airbag Readiness Light 0 98 for more information, including important safety information.
Charging System Light
The charging system light comes on briefly when the ignition is turned on, but the engine is not running, as a check to show the light is working. It should go out when the engine is started.
If the light stays on or comes on while driving, there may be a problem with the electrical charging system. Have it checked by your dealer. Driving while this light is on could drain the battery.
When this light comes on or is flashing, the Driver Information Center (DIC) also displays a message.
If a short distance must be driven with the light on, be sure to turn off all accessories, such as the radio and air conditioner. Find a safe place to stop the vehicle.
Malfunction Indicator Lamp (Check Engine Light)
This light is part of the vehicle’s emission control onboard diagnostic system. If this light is on while the engine is running, a malfunction has been detected and the vehicle may require service. The light should come on to show that it is working when the ignition is in Service Mode.
Malfunctions are often indicated by the system before any problem is noticeable. Being aware of the light and seeking service promptly when it comes on may prevent damage.
Caution
If the vehicle is driven continually with this light on, the emission control system may not work as well, the fuel economy may be lower, and the vehicle may not run smoothly. This could lead to costly repairs that might not be covered by the vehicle warranty.
Caution
Modifications to the engine, transmission, exhaust, intake, or fuel system, or the use of replacement tires that do not meet the original tire specifications, can cause this light to come on. This could lead to costly repairs not covered by the vehicle warranty. This could also affect the vehicle’s ability to pass an Emissions Inspection / Maintenance test.
If the light is flashing: A malfunction has been detected that could damage the emission control system and increase vehicle emissions. Diagnosis and service may be required.
To help prevent damage, reduce vehicle speed and avoid hard accelerations and uphill grades. If towing a trailer, reduce the amount of cargo being hauled as soon as possible.
If the light continues to flash, find a safe place to park. Turn the vehicle off and wait at least 10 seconds before restarting the engine. If the light is still flashing, follow the previous guidelines and see your dealer for service as soon as possible.
If the light is on steady: A malfunction has been detected. Diagnosis and service may be required.
Check the following:
- If fuel has been added to the vehicle using the capless fuel funnel adapter, make sure that it has been removed. See “Filling the Tank with a Portable Gas Can” under Filling the Tank 0 243. The diagnostic system can detect if the adapter has been left installed in the vehicle, allowing fuel to evaporate into the atmosphere. A few driving trips with the adapter removed may turn off the light.
- Poor fuel quality can cause inefficient engine operation and poor driveability, which may go away once the engine is warmed up. If this occurs, change the fuel brand. It may require at least one full tank of the proper fuel to turn the light off.
If the light remains on, see your dealer.
