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 396
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.

Automatic Transmission Fluid
When to Check and Change Automatic
Transmission Fluid
A good time to check the automatic transmission
uid level is when the engine oil is changed.
Change the uid at the intervals listed inAdditional
Required Services on page 504, and be sure to
use the transmission uid listed inRecommended
Fluids and Lubricants on page 511.
How to Check Automatic Transmission
Fluid
Because this operation can be a little difficult, you
may choose to have this done at the dealer/retailer
service department.
If you do it yourself, be sure to follow all the
instructions here, or you could get a false reading
on the dipstick.Notice:Too much or too little uid can
damage your transmission. Too much can
mean that some of the uid could come out
and fall on hot engine parts or exhaust system
parts, starting a re. Too little uid could
cause the transmission to overheat. Be sure to
get an accurate reading if you check your
transmission uid.
Wait at least 30 minutes before checking the
transmission uid level if you have been driving:
When outside temperatures are above
90°F (32°C).
At high speed for quite a while.
In heavy traffic — especially in hot weather.
While pulling a trailer.
To get the right reading, the uid should be at
normal operating temperature, which is 180°F to
200°F (82°C to 93°C).
Get the vehicle warmed up by driving about
15 miles (24 km) when outside temperatures are
above 50°F (10°C). If it is colder than 50°F (10°C),
you may have to drive longer.
404

Checking the Fluid Level
Prepare the vehicle as follows:
1. Park the vehicle on a level place. Keep the
engine running.
2. With the parking brake applied, place the shift
lever in PARK (P).
3. With your foot on the brake pedal, move the
shift lever through each gear, pausing for
about three seconds in each one. Then,
position the shift lever in PARK (P).
4. Let the engine run at idle for three to
ve minutes.
Then, without shutting off the engine, follow
these steps:
The transmission uid
dipstick cap has this
symbol on it, and
is located near the
front of the engine
compartment.SeeEngine Compartment Overview on page 396
for more information on location.
1. Remove the dipstick and wipe it with a clean
rag or paper towel.
2. Reinstall back in all the way, wait
three seconds and then pull it back out
again.
3. Check both sides of the dipstick, and read the
lower level. The uid level must be in the
crosshatched area.
4. If the uid level is in the acceptable range,
twist & lock dipstick cap in place.
405

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.

(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.
