Warning Lights, Gauges, and Indicators

Warning lights and gauges can signal that something is wrong before it becomes serious enough to cause an expensive repair or replacement. Paying attention to the warning lights and gauges could prevent injury.
Some warning lights come on briefly when the engine is started to indicate they are working. When one of the warning lights comes on and stays on while driving, or when one of the gauges shows there may be a  problem, check the section that explains what to do. Waiting to do repairs can be costly and even dangerous.

Instrument Cluster

Reconfigurable Instrument Cluster
The uplevel cluster display layout can be changed.
The Balanced configuration has three interactive display zones: one in the center of each of the gauges.
The Enhanced configuration has three interactive display zones.
The Performance configuration has two interactive display zones.

Use the five-way control on the right side of the steering wheel to move between the different display zones and scroll through the different displays.
To change the cluster configuration:

1. Find the Options page in one of the interactive display zones on the cluster.
2. Press SEL to enter the Options menu.
3. Scroll down to highlight Display Layout. Then press SEL to select it.
4. Each layout in the menu is represented by a small preview image of the display layout. Scroll up or down and highlight the selection. Press SEL to select the desired cluster configuration.

Cluster Application Displays
The cluster can display information regarding Navigation, Audio, and
Phone. On the base cluster, a speedometer can also be displayed in the center zone.

Navigation
If there is no active route, a compass will be displayed. If there is an active route, press SEL to end route guidance or turn the voice prompts on or off.

Audio
While the Audio application page is displayed, press SEL to enter the
Audio menu. In the Audio menu, search for music, select from favorites, or change the audio source

Phone
While the Phone application page is displayed, press SEL to enter the Phone menu. In the Phone menu, if there is no active phone call, view recent calls, select from favorites, or scroll through contacts. If there is an active call, mute the phone or switch to handset operation.

Cluster Options Menu

1. Use the five-way control on the right side of the steering wheel to find the Options page in one of the interactive display zones on the cluster.
2. Press SEL on the center of the five-way control to enter the Options menu

Speedometer
The speedometer shows the vehicle’s 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). See Driver Information Center (DIC) 0 136.

Tachometer
The tachometer displays the engine speed in revolutions per minute (rpm).

Caution
If the engine is operated with the rpm’s in the warning area at the high end of the tachometer, the vehicle could be damaged, and the damage would not be covered by the vehicle warranty. Do not operate the engine with the rpm’s in the warning area.

Fuel Gauge
When the ignition is on, the fuel gauge indicates about 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 nears empty, the low fuel light comes on. There still is a little fuel left, but the vehicle should be refueled 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 actually 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 or speeding up.
• 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.

Boost Gauge (Performance Configuration Only)
This gauge indicates boost under heavier throttle.
It displays the air pressure level in the intake manifold before it enters the engine’s combustion chamber.
The gauge is automatically centered at zero every time the engine is started.
Actual boost is displayed from this zero point. Changes in ambient pressure, such as driving in mountains and changing weather, will slightly change the zero reading.

Engine Oil Temperature Gauge (Performance Configuration Only)
This gauge shows the engine oil temperature.
If the gauge pointer moves into the high end, it means that the engine oil has overheated. If the vehicle has been operated under normal driving conditions, 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.

Passenger Seat Belt Reminder Light
There is a passenger seat belt reminder light near the passenger airbag status indicator. See Passenger Sensing System 0 81.
When the vehicle is started, this light flashes and a chime may come on to remind passengers to fasten their seat belt. Then the light stays on solid until the belt is buckled. This cycle continues several times if the passenger remains or becomes unbuckled while the vehicle is moving.
If the passenger seat belt is buckled, neither the chime nor the light comes on.
The front passenger seat belt reminder light and chime may turn 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
This light shows if there is an electrical problem with the airbag system. The system check includes the airbag sensor(s), the passenger
sensing system, the pretensions, the airbag modules, the wiring, and the crash sensing and diagnostic module. For more information on the airbag system, see Airbag System 0 75.
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.

Passenger Airbag Status Indicator
The vehicle has a passenger sensing system. See Passenger Sensing System 0 81 for important safety information.
The passenger airbag status indicator is in the overhead console.

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 the on or off symbol, to let you know the status of the front outboard passenger frontal airbag and knee airbag.

Charging System Light
On some vehicles 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. For vehicles with a reconfigurable cluster, this light may not come on when the ignition is turned on.
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.

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. See Ignition Positions 0 181.
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.
