CHECKING OIL LEVEL
To ensure proper engine lubrication, the engine oil
must be maintained at the correct level. Check the
oil level at regular intervals, such as every fuel
stop. The best time to check the engine oil level is
about five minutes after a fully warmed up engine
is shut off.
Checking the oil while the vehicle is on level ground
will improve the accuracy of the oil level readings.
There are four possible dipstick types:
Crosshatched zone.
Crosshatched zone marked SAFE.
Crosshatched zone marked with MIN at the low
end of the range and MAX at the high end of the
range.
Crosshatched zone marked with dimples at the
MIN and the MAX ends of the range.
NOTE:Always maintain the oil level within the crosshatch
markings on the dipstick.
Adding 1 qt (1 L) of oil when the reading is at the
low end of the dipstick range will raise the oil level
to the high end of the range marking.
ADDING WASHER FLUID
The fluid reservoir is located under the hood and
the fluid level should be checked at regular
intervals. Fill the reservoir with windshield washer
solvent only (not radiator antifreeze). When
refilling the washer fluid reservoir, take some
washer fluid and apply it to a cloth or towel and
wipe the wiper blades clean. This will help blade
performance.
To prevent freeze-up of your windshield washer
system in cold weather, select a solution or mixture
that meets or exceeds the temperature range of
your climate. This rating information can be found
on most washer fluid containers.After the engine has warmed up, operate the
defroster for a few minutes to reduce the
possibility of smearing or freezing the fluid on the
cold windshield. Windshield washer solution used
with water as directed on the container, aids
cleaning action, reduces the freezing point to avoid
line clogging, and is not harmful to paint or trim.MAINTENANCE-FREE BATTERY
Your vehicle is equipped with a maintenance-free
battery. You will never have to add water, and
periodic maintenance is not required.
NOTE:Replacement batteries should both be of equal
capacity to prevent damage to the vehicle's
charging system.
CAUTION!
Overfilling or underfilling the crankcase will
cause oil aeration or loss of oil pressure. This
could damage your engine.
WARNING!
Commercially available windshield washer
solvents are flammable. They could ignite and
burn you. Care must be exercised when filling or
working around the washer solution.
WARNING!
Battery fluid is a corrosive acid solution and
can burn or even blind you. Do not allow
battery fluid to contact your eyes, skin, or
clothing. Do not lean over a battery when
attaching clamps. If acid splashes in eyes or
on skin, flush the area immediately with large
amounts of water Ú

AUTOMATIC TRANSMISSION
Special Additives
The manufacturer strongly recommends against
using any special additives in the transmission.
Automatic Transmission Fluid (ATF) is an
engineered product and its performance may be
impaired by supplemental additives. Therefore, do
not add any fluid additives to the transmission. The
only exception to this policy is the use of special
dyes for diagnosing fluid leaks in 6-speed
transmissions. Avoid using transmission sealers as
they may adversely affect seals.
Fluid Level Check — 8-Speed Transmission
The fluid level is preset at the factory and does not
require adjustment under normal operating
conditions. Routine fluid level checks are not
required, therefore the transmission has no
dipstick. An authorized dealer can check your
transmission fluid level using special service tools. If you notice fluid leakage or transmission
malfunction, visit an authorized dealer
immediately to have the transmission fluid level
checked. Operating the vehicle with an improper
fluid level can cause severe transmission damage.
Fluid Level Check — 6-Speed Transmission
It is best to check the fluid level when the
transmission is at normal operating temperature
(158-176°F / 70-80°C). This normally occurs
after at least 15 miles (25 km) of driving. At normal
operating temperature the fluid cannot be held
comfortably between the fingertips. You can read
the transmission sump temperature in the
instrument cluster screen Ú page 89.
Use the following procedure to check the
transmission fluid level properly:

1. Monitor the transmission temperature using the instrument cluster display, and operate
the vehicle as required to reach the normal
operating temperature. If the transmission is
not functioning properly, or the vehicle cannot be driven, see the following Note and Caution
about checking the fluid level at colder
temperatures.

2. Park the vehicle on level ground.
3. Run the engine at normal idle speed for at least 60 seconds, and leave the engine
running for the rest of this procedure.
4. Fully apply the parking brake, and press the brake pedal.
5. Place the gear selector momentarily into each gear position (allowing time for the
transmission to fully engage in each position),
ending with the transmission in PARK.
6. Remove the dipstick, wipe it clean and reinsert it until seated.
7. Remove the dipstick again and note the fluid level on both sides. The fluid level reading is
only valid if there is a solid coating of oil on
both sides of the dipstick. Note that the holes
in the dipstick will be full of fluid if the actual
level is at or above the hole. The fluid level
should be between the “HOT” (upper)
reference holes on the dipstick at normal
operating temperature. If the fluid level is low,
add fluid through the dipstick tube to bring it to
the proper level. Do not overfill. Use ONLY the
specified fluid Ú page 421. After adding any
quantity of oil through the dipstick tube, wait a
CAUTION!
Do not use chemical flushes in your
transmission as the chemicals can damage your
transmission components. Such damage is not
covered by the New Vehicle Limited Warranty.
CAUTION!
If a transmission fluid leak occurs, visit an
authorized dealer immediately. Severe
transmission damage may occur. An authorized
dealer has the proper tools to adjust the fluid
level accurately.

SERVICING AND MAINTENANCE373
minimum of two minutes for the oil to fully
drain into the transmission before rechecking
the fluid level.
NOTE:If it is necessary to check the transmission below
the operating temperature, the fluid level should
be between the two “COLD” (lower) holes on the
dipstick with the fluid at 60-70°F / 16-21°C. Only
use the COLD region of the dipstick as a rough
reference when setting the fluid level after a trans -
mission service or fluid change. Re-check the fluid
level, and adjust as required, once the trans -
mission reaches normal operating temperature.
8. Reinsert the dipstick. Check for leaks. Release the parking brake.
NOTE:If it is necessary to check the transmission below
the operating temperature, the fluid level should
be between the two COLD (lower) holes on the
dipstick with the fluid at 68-86°F / 20-30°C. Only
use the COLD region of the dipstick as a rough
reference when setting the fluid level after a trans -
mission service or fluid change. Re-check the fluid
level, and adjust as required, once the trans -
mission reaches normal operating temperature.
Fluid And Filter Changes — 8-Speed
Transmission
Under normal operating conditions, the fluid
installed at the factory will provide satisfactory
lubrication for the life of the vehicle.
Routine fluid and filter changes are not required.
However, change the fluid and filter if the fluid
becomes contaminated (with water, etc.), or if the
transmission is disassembled for any reason.
Fluid And Filter Changes — 6-Speed
Transmission
For the proper maintenance intervals Úpage 344.
In addition, change the fluid and filters if the fluid
becomes contaminated (with water, etc.), or if the
transmission is disassembled for any reason.
Selection Of Lubricant
It is important to use the proper transmission fluid
to ensure optimum transmission performance and
life. Use only the manufacturer’s specified
transmission fluid Ú page 421. It is important to
maintain the transmission fluid at the correct level
using the recommended fluid. No chemical flushes
should be used in any transmission; only the
approved lubricant should be used.
CAUTION!
If the fluid temperature is below 50°F (10°C) it
may not register on the dipstick. Do not add fluid
until the temperature is elevated enough to
produce an accurate reading. Run the engine at
idle, in PARK, to warm the fluid.
CAUTION!
If the fluid temperature is below 50°F (10°C) it
may not register on the dipstick. Do not add fluid
until the temperature is elevated enough to
produce an accurate reading. Run the engine at
idle, in PARK, to warm the fluid.
CAUTION!
Using a transmission fluid other than the
manufacturer’s recommended fluid may cause
deterioration in transmission shift quality and/or
torque converter shudder, and (for 6-speed
transmissions) will require more frequent fluid
and filter changes Ú page 421.
