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.

•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.
