Checking Engine Oil
It is a good idea to check the engine oil every time
you get fuel. In order to get an accurate reading,
the oil must be warm and the vehicle must be
on level ground.
The engine oil dipstick handle is a yellow loop.
SeeEngine Compartment Overview on page 364
for the location of the engine oil dipstick.
1. Turn off the engine and give the oil several
minutes to drain back into the oil pan. If you
do not do this, the oil dipstick might not
show the actual level.
2. Pull out the dipstick and clean it with a paper
towel or cloth, then push it back in all the
way. Remove it again, keeping the tip down,
and check the level.

8. Then replace the pressure cap. At any time
during this procedure if coolant begins to ow
out of the ller neck, reinstall the pressure
cap. Be sure the arrows on the pressure cap
line up properly.
9. Then ll the coolant recovery tank to the full
cold mark.
10. Put the cap back on the coolant recovery tank.Power Steering Fluid

When to Check Power Steering Fluid
It is not necessary to regularly check power steering
uid unless you suspect there is a leak in the
system or you hear an unusual noise. A uid loss
in this system could indicate a problem. Have the
system inspected and repaired.
Filling in the Coolant Recovery Tank
387

Notice:
When using concentrated washer uid,
follow the manufacturer’s instructions
for adding water.
Do not mix water with ready-to-use washer
uid. Water can cause the solution to freeze
and damage your washer uid tank and
other parts of the washer system. Also,
water does not clean as well as washer
uid.
Fill your washer uid tank only
three-quarters full when it is very cold.
This allows for expansion if freezing
occurs, which could damage the tank
if it is completely full.
Do not use engine coolant (antifreeze) in
your windshield washer. It can damage your
washer system and paint.
Brakes
Brake Fluid
Your brake master
cylinder reservoir
is lled with DOT-3
brake uid. SeeEngine
Compartment Overview
on page 364for the
location of the reservoir.
There are only two reasons why the brake uid
level in the reservoir might go down. The rst is that
the brake uid goes down to an acceptable level
during normal brake lining wear. When new linings
are put in, the uid level goes back up. The other
reason is that uid is leaking out of the brake
system. If it is, you should have your brake system
xed, since a leak means that sooner or later your
brakes will not work well, or will not work at all.

At Each Fuel Fill
It is important to perform these underhood checks
at each fuel ll.
Engine Oil Level Check
Check the engine oil level and add the proper oil if
necessary. SeeEngine Oil on page 365for
further details.
Notice:It is important to check your oil
regularly and keep it at the proper level. Failure
to keep your engine oil at the proper level
can cause damage to your engine not covered
by your warranty.
Engine Coolant Level Check
Check the engine coolant level and add
DEX-COOL®coolant mixture if necessary. See
Engine Coolant on page 375for further details.
Windshield Washer Fluid Level Check
Check the windshield washer uid level in
the windshield washer uid reservoir and add the
proper uid if necessary.
At Least Once a Month
Tire Ination Check
Visually inspect your vehicle’s tires and make sure
they are inated to the correct pressures. Do not
forget to check the spare tire. SeeInation - Tire
Pressure on page 413. Check to make sure the
spare tire is stored securely. SeeChanging a Flat
Tire on page 428.
Tire Wear Inspection
Tire rotation may be required for high mileage
highway drivers prior to the Engine Oil Life System
service notication. Check the tires for wear
and, if necessary, rotate the tires. SeeTire
Inspection and Rotation on page 416.
