How to Add Automatic Transmission
Fluid
Refer to the Maintenance Schedule to determine
what kind of transmission uid to use. See
Recommended Fluids and Lubricants on page 511.
If the uid level is low, add only enough of the
proper uid to bring the level into the crosshatched
area on the dipstick.
1. Remove the dipstick.
2. Using a long-neck funnel, add enough uid at
the dipstick hole to bring it to the proper level.
It does not take much uid, generally
less than one half of a pint (0.25 L).
Do not overll.
Notice:Use of the incorrect automatic
transmission uid may damage your vehicle,
and the damages may not be covered by
your warranty. Always use the automatic
transmission uid listed inRecommended
Fluids and Lubricants on page 511.
3. After adding uid, recheck the uid level as
described under “How to Check Automatic
Transmission Fluid,” earlier in this section.
4. When the correct uid level is obtained,
twist & lock dipstick cap in place.
Engine Coolant
The cooling system in your vehicle is lled with
DEX-COOL®engine coolant. This coolant is
designed to remain in your vehicle for ve years or
150,000 miles (240 000 km), whichever occurs
rst, if you add only DEX-COOL
®extended
life coolant.
The following explains your cooling system and
how to add coolant when it is low. If you have
a problem with engine overheating or if you need
to add coolant to the radiator, seeEngine
Overheating on page 410.
A 50/50 mixture of clean, drinkable water and
DEX-COOL
®coolant will:
Give freezing protection down to
−34°F (−37°C).
Give boiling protection up to 265°F (129°C).
Protect against rust and corrosion.
Help keep the proper engine temperature.
Let the warning lights and gages work as
they should.
406

Radiator Pressure Cap
Notice:If the pressure cap is not tightly
installed, coolant loss and possible engine
damage may occur. Be sure the cap is properly
and tightly secured.
SeeEngine Compartment Overview on page 396
for more information on location.
Engine Overheating
There is an engine coolant temperature gage on
your vehicle’s instrument panel. SeeEngine
Coolant Temperature Gage on page 225.
Your vehicle may also have an ENGINE
OVERHEATED IDLE ENGINE and ENGINE
OVERHEATED STOP ENGINE message
displayed in the Driver Information Center (DIC).
SeeDIC Warnings and Messages on page 244.
If Steam Is Coming From Your Engine
{CAUTION:
Steam from an overheated engine can
burn you badly, even if you just open the
hood. Stay away from the engine if you
see or hear steam coming from it. Turn it
off and get everyone away from the
vehicle until it cools down. Wait until
there is no sign of steam or coolant
before you open the hood.
CAUTION: (Continued)
410

If you no longer have the overheat warning,
you can drive. Just to be safe, drive slower for
about 10 minutes. If the warning does not
come back on, you can drive normally.
If the warning continues, pull over, stop, and park
your vehicle right away.
If there is still no sign of steam, idle the engine for
three minutes while you are parked. If you still
have the warning, turn off the engine and
get everyone out of the vehicle until it cools down.
Also, see “Overheated Engine Protection
Operating Mode” later in this section.
You may decide not to lift the hood but to get
service help right away.Overheated Engine Protection
Operating Mode
This emergency operating mode lets your vehicle
be driven to a safe place in an emergency situation.
If an overheated engine condition exists, an
overheat protection mode which alternates ring
groups of cylinders helps prevent engine damage.
In this mode, there is a signicant loss in power and
engine performance. The temperature gage
indicates an overheat condition exists. Driving
extended miles (km) 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. SeeEngine Oil on page 397.

Windshield Washer Fluid
What to Use
When adding windshield washer uid, be sure to
read the manufacturer’s instructions before
use. If operating your vehicle in an area where the
temperature may fall below freezing, use a uid
that has sufficient protection against freezing.
Adding Washer Fluid
When the windshield washer uid reservoir is low,
a WASHER FLUID LOW ADD FLUID message
will be displayed on the Driver Information Center
(DIC). SeeDIC Warnings and Messages on
page 244for more information.
Open the cap with the
washer symbol on it.
Add washer uid
until the tank is full. See
Engine Compartment
Overview on page 396
for reservoir location.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 the washer uid tank only
three-quarters full when it is very cold.
This allows for uid 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
the vehicle’s windshield washer system
and paint.
420

(g)A fluid loss in any vehicle system could
indicate a problem. Have the system inspected
and repaired and the fluid level checked. Add fluid
if needed.
(h)Change automatic transmission fluid if the
vehicle is mainly driven under one or more
of these conditions:
In heavy city traffic where the outside
temperature regularly reaches 90°F
(32°C) or higher.
In hilly or mountainous terrain.
When doing frequent trailer towing.
Uses such as found in taxi, police, or
delivery service.
(i)Drain, flush, and refill cooling system.
This service can be complex; you should have
your dealer/retailer perform this service. See
Engine Coolant on page 406 for what to use.
Inspect hoses. Clean radiator, condenser, pressure
cap, and filler neck. Pressure test the cooling
system and pressure cap.(j)Check system for interference or binding and
for damaged or missing parts. Replace parts
as needed. Replace any components that have
high effort or excessive wear. Do not lubricate
accelerator or cruise control cables.
(k)Visually inspect belt for fraying, excessive
cracks, or obvious damage. Replace belt if
necessary.
(l)If you drive regularly under dusty conditions,
inspect the filter at each engine oil change.
Owner Checks and Services
These owner checks and services should be
performed at the intervals specied to help ensure
the safety, dependability, and emission control
performance of your vehicle. Your dealer/retailer
can assist you with these checks and services.
Be sure any necessary repairs are completed
at once. Whenever any uids or lubricants are
added to your vehicle, make sure they are
the proper ones, as shown inRecommended
Fluids and Lubricants on page 511.
