Instrument Cluster Control
Adjusting instrument cluster illumination

- The brightness of the instrument panel illumination is displayed.
- If the brightness reaches the maximum or minimum level, a chime will sound.
WARNING
Never adjust the instrument cluster while driving. Doing so could lead to driver distraction which may cause an accident and lead to vehicle damage, serious injury, or death.
Gauges and Meters
Speedometer 
The speedometer indicates the speed of the vehicle and is calibrated in miles per hour (MPH) and/or kilometers per hour (km/h).
Tachometer 
The tachometer indicates the approximate number of engine revolutions per minute (RPM). Use the tachometer to select the correct shift points and to prevent lugging and/or over-revving the engine.
NOTICE
Do not operate the engine within the tachometer’s RED ZONE. This may cause severe engine damage.
Engine coolant temperature gauge 
This gauge indicates the temperature of the engine coolant when the ignition switch is in the ON position.
NOTICE
If the gauge pointer moves beyond the normal range area toward the “H” position, it indicates overheating that may damage the engine. Do not continue driving with an overheated engine. If your engine overheats, refer to “If the Engine Overheats” in Chapter 7.
WARNING
Never remove the radiator cap or reservoir cap when the engine is hot. The engine coolant is under pressure and could severely burn. Wait until the engine is cool before adding coolant to the reservoir.
Fuel gauge 
This gauge indicates the approximate amount of fuel remaining in the fuel tank.
Information
- The fuel tank capacity is given in chapter 2.
- The fuel gauge is supplemented by a low fuel warning light, which will illuminate when the fuel tank is nearly empty.
- On inclines or curves, the fuel gauge pointer may fluctuate or the low fuel warning light may come on earlier than usual due to the movement of fuel in the tank.
WARNING
Running out of fuel can expose vehicle occupants to danger. You must stop and obtain additional fuel as soon as possible after the warning light comes on or when the gauge indicator comes close to the “E (Empty)” level.
NOTICE
Avoid driving with an extremely low fuel level. Running out of fuel could cause the engine to misfire and damage the catalytic converter. Outside temperature gauge
Type A, B 
Type C 
This gauge indicates the current outside air temperature by 1°F (1°C).-
- Temperature range: -40°F ~ 140°F (40°C ~ 60°C)
Note that the temperature indicated on the LCD display may not change as quickly as the outside temperature (there may be a slight delay before the temperature changes.) You can change the temperature unit from °F to °C or °C to °F in the User Settings mode in the cluster: Go to User Settings Mode → Other → Temperature Unit. For vehicles equipped with Automatic Climate Control, you can also:
- Press and hold the AUTO and OFF buttons on the climate control unit for 3 seconds
Both the temperature unit on the cluster LCD display and climate control screen will change.
Odometer Type A, B 
The odometer indicates the total distance that the vehicle has been driven and should be used to determine when periodic maintenance should be performed.
Range
- The range is the estimated distance the vehicle can be driven with the remaining fuel.
- If the estimated distance is below 1 mi. (1 km), the trip computer will display “—-” as range.
Information
- If the vehicle is not on level ground or the battery power has been interrupted, the range function may not operate correctly.
- The range may differ from the actual driving distance as it is only an estimate of the available driving range for the vehicle and driving conditions.
- The trip computer may not register additional fuel if less than 1.6 gallons (6 liters) of fuel are added to the vehicle.
- The range may vary significantly based on driving conditions, driving habits, and the condition of the vehicle.
Transmission Shift Indicator
Automatic transmission shift indicator Type A 
Type B 
Shift Indicator Pop-up
The pop-up that indicates the current gear position is displayed in the cluster for about 2 seconds when shifting into other positions (P/R/N/D). The shift indicator pop-up function can be activated or deactivated from the User Settings mode in the cluster LCD display.
