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 or Engine Start/Stop button is ON.
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 vehicle overheats, refer to "If the Engine Overheats" in chapter 6.
WARNING
Never remove the radiator cap WARNING 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
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, damaging the catalytic converter.
Odometer
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
Information
Outside temperature gauge
This gauge indicates the current outside air temperatures by 1°F (1°C).
- Temperature range : -40°F ~ 140°F (-40°C ~ 60°C)
The outside temperature on the display may not change immediately like a general thermometer (to avoid distracting the driver).
To change the temperature unit from °F to °C or °C to °F:
For conventional cluster:
- Press the TRIP button for more than 5 seconds on the steering wheel.
For supervision cluster:
- Go to the User Settings Mode ➝ Other ➝ Temperature Unit. Select your desired unit.
For vehicles equipped with Automatic Climate Control, you can also:
- Press the AUTO button while pressing the OFF button on the climate control unit for 3 seconds
Both the temperature unit on the cluster LCD display and climate control screen will change.
