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.

Storing the Flat Tire
Notice:Storing the full-size at tire in the
underbody hoist system can expose it to heat
from the exhaust system. This can damage
the tire and underbody hoist system. Do not
store the full-size at tire in the underbody
hoist system.
1. Remove the cable package from the jack
storage area.
2. Remove the small center cap by tapping the
back of the cap with the extension of the
shaft, if the vehicle has aluminum wheels.
3. Put the at tire in the rear storage area with
the valve stem pointing toward the rear of the
vehicle.4. Hook on end of the cable onto the outside
portion of the liftgate hinge opposite (B).
5. Pull the cable (A) through the door striker (E),
the center of the wheel (D), and the plastic
spare tire heat shield (C), as shown.

Sheet Metal Damage
If the vehicle is damaged and requires sheet metal
repair or replacement, make sure the body repair
shop applies anti-corrosion material to parts
repaired or replaced to restore corrosion protection.
Original manufacturer replacement parts will
provide the corrosion protection while maintaining
the warranty.
Finish Damage
Any stone chips, fractures or deep scratches
in the nish should be repaired right away.
Bare metal will corrode quickly and may develop
into major repair expense.
Minor chips and scratches can be repaired with
touch-up materials available from your dealer/
retailer. Larger areas of nish damage can
be corrected in your dealer’s/retailer’s body and
paint shop.
Underbody Maintenance
Chemicals used for ice and snow removal and dust
control can collect on the underbody. If these are
not removed, corrosion and rust can develop on the
underbody parts such as fuel lines, frame, oor pan,
and exhaust system even though they have
corrosion protection.
At least every spring, ush these materials from the
underbody with plain water. Clean any areas where
mud and debris can collect. Dirt packed in close
areas of the frame should be loosened before being
ushed. Your dealer/retailer or an underbody car
washing system can do this for you.
Chemical Paint Spotting
Some weather and atmospheric conditions can
create a chemical fallout. Airborne pollutants can
fall upon and attack painted surfaces on the
vehicle. This damage can take two forms: blotchy,
ring-shaped discolorations, and small, irregular
dark spots etched into the paint surface.
Although no defect in the paint job causes this,
we will repair, at no charge to the owner, the
surfaces of new vehicles damaged by this fallout
condition within 12 months or 12,000 miles
(20 000 km) of purchase, whichever occurs rst.
