Transmission Fluid TemperatureGauge
Indicates transmission fluid temperature.At normal operating temperature, the levelindicator will be in the normal range. If thetransmission fluid temperature exceedsthe normal range, stop the vehicle as soonas safely possible and verify the airflow isnot restricted such as snow or debrisblocking airflow through the grill. Also,higher than normal operating temperaturecan be caused by special operationconditions (i.e. snowplowing, towing oroff-road use). Refer to Special operatingconditions in the scheduled maintenanceinformation for instructions. Operating the
transmission for extended periods of timewith the gauge in the higher than normalarea may cause internal transmissiondamage. Altering the severity of the drivingconditions is recommended to lower thetransmission temperature into the normalrange. If the gauge continues to show hightemperatures, see your authorized dealer.
Fuel Gauge
Note:The fuel gauge may vary slightlywhen your vehicle is moving or on a gradient.
Switch the ignition on. The fuel gauge willindicate approximately how much fuel isleft in the fuel tank. The arrow adjacent tothe fuel pump symbol indicates on whichside of your vehicle the fuel filler door islocated.
The needle should move toward F whenyou refuel your vehicle. If the needle pointsto E after adding fuel, this indicates yourvehicle needs service soon.
After refueling some variability in needleposition is normal:
•It may take a short time for the needleto reach F after leaving the gas station.This is normal and depends upon theslope of pavement at the gas station.
•The fuel amount dispensed into thetank is a little less or more than thegauge indicated. This is normal anddepends upon the slope of pavementat the gas station.
•If the gas station nozzle shuts offbefore the tank is full, try a differentgas pump nozzle.
