4. Fill the radiator with the proper DEX-COOL®
coolant mixture, up to the base of the ller
neck. SeeEngine Coolant on page 375
for more information about the proper coolant
mixture.
If you see a stream of coolant coming from an
air bleed valve, close the valve. Otherwise,
close the valves after the radiator is lled.
5. Rinse or wipe any spilled coolant from the
engine and the compartment.6. Start the engine and let it run until you can
feel the upper radiator hose getting hot.
Watch out for the engine cooling fans.
7. By this time, the coolant level inside the
radiator ller neck may be lower. If the level is
lower, add more of the proper DEX-COOL
®
coolant mixture through the ller neck until the
level reaches the base of the ller neck.

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

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.

Cold Tire Pressure:The amount of air pressure
in a tire, measured in pounds per square inch (psi)
or kilopascals (kPa) before a tire has built up heat
from driving. SeeInation - Tire Pressure on
page 413.
Curb Weight:This means the weight of a motor
vehicle with standard and optional equipment
including the maximum capacity of fuel, oil, and
coolant, but without passengers and cargo.
DOT Markings:A code molded into the sidewall
of a tire signifying that the tire is in compliance with
the U.S. Department of Transportation (DOT)
motor vehicle safety standards. The DOT code
includes the Tire Identication Number (TIN), an
alphanumeric designator which can also identify the
tire manufacturer, production plant, brand, and date
of production.
GVWR:Gross Vehicle Weight Rating. See
Loading Your Vehicle on page 332.
GAWR FRT:Gross Axle Weight Rating for the
front axle. SeeLoading Your Vehicle on page 332.
GAWR RR:Gross Axle Weight Rating for the
rear axle. SeeLoading Your Vehicle on page 332.Intended Outboard Sidewall:The side of an
asymmetrical tire, that must always face outward
when mounted on a vehicle.
Kilopascal (kPa):The metric unit for air pressure.
Light Truck (LT-Metric) Tire:A tire used on light
duty trucks and some multipurpose passenger
vehicles.
Load Index:An assigned number ranging from
1 to 279 that corresponds to the load carrying
capacity of a tire.
Maximum Ination Pressure:The maximum air
pressure to which a cold tire may be inated.
The maximum air pressure is molded onto
the sidewall.
Maximum Load Rating:The load rating for a tire
at the maximum permissible ination pressure
for that tire.
Maximum Loaded Vehicle Weight:The sum of
curb weight, accessory weight, vehicle capacity
weight, and production options weight.
Normal Occupant Weight:The number of
occupants a vehicle is designed to seat multiplied
by 150 lbs (68 kg). SeeLoading Your Vehicle
on page 332.

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.
