Vehicle Care

distances and/or towing a trailer in
the overheat protection mode
should be avoided.

Notice:

After driving in the

overheated engine protection
operating mode, to avoid engine
damage, allow the engine to cool
before attempting any repair. The
engine oil will be severely
degraded. Repair the cause of
coolant loss, change the oil and
reset the oil life system. See

Engine Oil on page 10-6

Engine Fan

The vehicle electric cooling fans
may be heard spinning at low speed
during most everyday driving. The
fans may turn off if no cooling is
required. Under heavy vehicle
loading, trailer towing, high outside
temperatures, or operation of the air
conditioning system, the fans may
change to high speed and an
increase in fan noise may be heard.
This is normal and indicates that the
cooling system is functioning

properly. The fans will change to low
speed when additional cooling is no
longer required.

for reservoir location.

When to Check Power Steering
Fluid

It is not necessary to regularly
check power steering fluid unless
there is a leak suspected in the
system or an unusual noise is
heard. A fluid loss in this system
could indicate a problem. Have the
system inspected and repaired.

How to Check Power Steering
Fluid

To check the power steering fluid:

1. Turn the key off and let the

engine compartment cool down.

2. Wipe the cap and the top of the

reservoir clean.

3. Unscrew the cap and wipe the

dipstick with a clean rag.

4. Replace the cap and completely

tighten it.

5. Remove the cap again and look

at the fluid level on the dipstick.
