4. Block the diagonally opposite
wheel.
5. Obtain the spare tire and jack
from their storage locations.
6. Use the tip of the lug wrench to
remove any wheel trim.
7. Loosen each wheel lug nut
one-half turn counterclockwise but
do not remove them until the wheel
is raised off the ground.
8. Position the jack according to the
following guides and turn the jack
handle clockwise until the wheel is
completely off the ground.
When one of the rear wheels is off the ground, the transmission
alone will not prevent the vehicle from moving or slipping off the
jack, even if the transmission is in P (Park). To prevent the vehicle
from moving when you change the tire, be sure that the parking brake
is set and the diagonally opposite wheel is blocked. If the vehicle slips
off the jack, someone could be seriously injured.

12. Remove the jack and fully
tighten the lug nuts in the order
shown.
13. Stow the flat tire. Refer to
Stowing the spare tire.
14. Stow the jack and lug wrench.
Make sure the jack is fastened so it
does not rattle when you drive.
15. Unblock the wheels.
16. Turn on the air suspension switch.
JUMP STARTING YOUR VEHICLE
The gases around the battery can explode if exposed to flames,
sparks, or lit cigarettes. An explosion could result in injury or
vehicle damage.
Batteries contain sulfuric acid which can burn skin, eyes, and
clothing, if contacted.
Do not attempt to push-start your vehicle. Automatic
transmissions do not have push-start capability; also, the
catalytic conveter may become damaged..
Preparing your vehicle
When the battery is disconnected or a new battery is installed, the
transmission must relearn its adaptive strategy. As a result of this, the
transmission may shift firmly. This operation is considered normal and
will not affect function or durability of the transmission. Over time, the
adaptive learning process will fully update transmission operation to its
optimum shift feel.
1.Use only a 12±volt supply to start your vehicle.
2. Do not disconnect the battery of the disabled vehicle as this could
damage the vehicle's electrical system.
3. Park the booster vehicle close to the hood of the disabled vehicle
making sure the two vehiclesdo nottouch. Set the parking brake on
both vehicles and stay clear of the engine cooling fan and other moving
parts.

3. Remove the jumper cable from the positive (+) terminal of the booster
vehicle's battery.
4. Remove the jumper cable from the positive (+) terminal of the
disabled vehicle's battery.
After the disabled vehicle has been started and the jumper cables
removed, allow it to idle for several minutes so the engine computer can
relearnits idle conditions.

TRANSMISSION FLUID
Checking automatic transmission fluid
Refer to your scheduled maintenance guide for scheduled intervals for
fluid checks and changes. Your transmission does not consume fluid.
However, the fluid level should be checked if the transmission is not
working properly, i.e., if the transmission slips or shifts slowly or if you
notice some sign of fluid leakage.
Automatic transmission fluid expands when warmed. To obtain an
accurate fluid check, drive the vehicle until it is at normal operating
temperature (approximately 30 km [20 miles]). If your vehicle has been
operated for an extended period at high speeds, in city traffic during hot
weather or pulling a trailer, the vehicle should be turned off for about 30
minutes to allow fluid to cool before checking.
1. Drive the vehicle 30 km (20 miles) or until it reaches normal operating
temperature.
2. Park the vehicle on a level surface and engage the parking brake.
3. With the parking brake engaged and your foot on the brake pedal,
start the engine and move the gearshift lever through all of the gear
ranges. Allow sufficient time for each gear to engage.
4. Latch the gearshift lever in P (Park) and leave the engine running.
5. Remove the dipstick, wiping it clean with a clean, dry lint free rag. If
necessary, refer toIdentifying components in the engine compartment
in this chapter for the location of the dipstick.
6. Install the dipstick making sure it is fully seated in the filler tube.
7. Remove the dipstick and inspect the fluid level. The fluid should be in
the designated area for normal operating temperature or ambient
temperature.
Low fluid level
Do not drive the vehicle if the fluid
level is at the bottom of the dipstick
and the ambient temperature is
above 10ÉC (50ÉF).

Correct fluid level
The transmission fluid should be checked at normal operating
temperature 66ÉC-77ÉC (150ÉF-170ÉF) on a level surface. The normal
operating temperature can be reached after approximately 30 km
(20 miles) of driving.
You can check the fluid without driving if the ambient temperature is
above 10ÉC (50ÉF). However, if fluid is added at this time, an overfill
condition could result when the vehicle reaches normal operating
temperature.
The transmission fluid should be in
this range if at normal operating
temperature (66ÉC-77ÉC
[150ÉF-170ÉF]).
The transmission fluid should be in
this range if at ambient temperature
(10ÉC-35ÉC [50ÉF-95ÉF]).
High fluid level
Fluid levels above the safe range
may result in transmission failure.
An overfill condition of transmission
fluid may cause shift and/or
engagement concerns and/or
possible damage.
High fluid levels can be caused by an overheating condition.
Adjusting automatic transmission fluid levels
Before adding any fluid, make sure the correct type is used. The type of
fluid used is normally indicated on the dipstick and also in the
Lubricant specificationssection in .
Use of a non-approved automatic transmission fluid may cause
internal transmission component damage.
If necessary, add fluid in 250 mL (1/2 pint) increments through the filler
tube until the level is correct.
