ator cooling fans operate and to check for coolant leaks from the radiator or
hoses.

CAUTION
■When inspecting under the hood of your vehicle
Observe the following precautions.
Failure to do so may result in serious injury such as burns.
●If steam is seen coming from under the h ood, do not open the hood until the steam
has subsided. The engine compartment may be very hot.
●Keep hands and clothing (especially a tie, a scarf or a muffler) away from the fans and
belts. Failure to do so may cause the hands or clothing to be caught, resulting in seri-
ous injury.
●Do not loosen the radiator cap or the cool ant reservoir cap while the engine and radi-
ator are hot. High temperature steam or coolant could spray out.
NOTICE
■When adding engine coolant
Add coolant slowly after the engine has cool ed down sufficiently. Adding cool coolant
to a hot engine too quickly can cause damage to the engine.
■To prevent damage to the cooling system
Observe the following precautions:
●Avoid contaminating the coolant with foreig n matter (such as sand or dust etc.).
●Do not use any coolant additive.

CAUTION
■When attempting to free a stuck vehicle
If you choose to push the vehicle back and forth to free it, make sure the surrounding
area is clear, to avoid striking other vehicles, objects or people. The vehicle may also
lunge forward or lunge back suddenly as it becomes free. Use extreme caution.
■When shifting the shift lever
Be careful not to shift the shift lever with the accelerator pedal depressed.
This may lead to unexpected rapid acceleration of the vehicle that may cause an acci-
dent and result in death or serious injury.

●Avoid spinning the wheels and depressing the accelerator pedal more than neces-
sary.
●If the vehicle remains stuck even after th ese procedures are performed, the vehicle
may require towing to be freed.
●When a warning message for the automatic transmission fluid temperature is dis-
played while attempting to free a stuck vehicle, immediately remove your foot from
the accelerator pedal and wait until the warning message disappears. Otherwise, the
transmission may become damaged. ( P. 531)
