IF YOUR ENGINE OVERHEATS 

If the vehicle is overheating, it will need to be 

serviced by an authorized dealer.
In any of the following situations, you can 

reduce the potential for overheating by taking 

the appropriate action.

On the highways — slow down.

In city traffic — while stopped, shift transmis

-

sion into NEUTRAL (N) , but do not increase 

engine idle speed.

CAUTION!

To avoid fuel spillage and overfilling, do not 

“top off” the fuel tank after filling.

WARNING!

Never have any smoking materials lit in or 

near the vehicle when the fuel door is open 

or the tank is being filled.

Never add fuel when the engine is running. 

This is in violation of most state and federal 

fire regulations and may cause the 

Malfunction Indicator Light to turn on.

A fire may result if fuel is pumped into a 

portable container that is inside of a 

vehicle. You could be burned. Always place 

fuel containers on the ground while filling.

CAUTION!

Driving with a hot cooling system could 

damage your vehicle. If the temperature 

gauge reads HOT (H), pull over and stop the 

vehicle. Idle the vehicle with the air 

conditioner turned off until the pointer drops 

back into the normal range. If the pointer 

remains on HOT (H), and you hear continuous 

chimes, turn the engine off immediately and 

call for service.
