Power distribution box
The power distribution box is
located in the engine
compartment. The power
distribution box contains
high-current fuses that protect
your vehicle's main electrical
systems from overloads.
Always disconnect the
battery before servicing
high current fuses.
Always replace the cover
to the Power Distribution
Box before reconnecting the
battery or refilling fluid
reservoirs.

3. Block the diagonally opposite
wheel.
4. Obtain the spare tire and jack
from their storage locations.
5. Use the tip of the lug wrench to
remove any wheel trim.
6. Loosen each wheel lug nuts
one-half turn counterclockwise but
do not remove them until the
wheel is raised off the ground.
7. Turn OFF the air suspension
switch (if equipped).
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.

2. While the engine idles, turn the
steering wheel left and right
several times.
3. Turn the engine off.
4. Check the fluid level in the
reservoir. It should be between the
MIN and MAX lines. Do not add
fluid if the level is in this range.
5. If the fluid is low, add fluid in
small amounts, continuously
checking the level until it reaches
the range between the MIN and
MAX lines. Be sure to put the cap
back on the reservoir.

chapter.
An overfill condition of
transmission fluid may cause
shift and/or engagement
concerns and/or possible
damage.
Do not drive the vehicle if the fluid
level is below the hole at the
bottom of the blade type dipstick
(4R70W transmission) or below
the COLD area on the bullet type
dipstick (E4OD transmission) and
outside temperatures are above
10ÉC (50ÉF) (see figure to the
right).
Your transmission does not use up
fluid. However, it is recommended
that you check the transmission
fluid at least twice a year. 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.
Transmission fluid should be
checked at normal operating
temperatures 66ÉC-77ÉC
(150ÉF-170ÉF) on a level surface.
The normal operating temperature
can be reached after approximately
32 km (20 miles) of driving.
The transmission fluid should be in
this range if at normal operating
temperature (66ÉC-77ÉC
[150ÉF-170ÉF]) (see figure to the
right).

The transmission fluid should be in
this range if at room temperature
(10ÉC-35ÉC [50ÉF-95ÉF]) (see
figure to the right).
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 the fluid
to cool before checking.
1. Park the vehicle on a level
surface and engage the parking
brake.
2. 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.
3. Latch the gearshift lever in P
(Park) and leave the engine
running.
4. Remove the dipstick, wiping it
clean with a clean, dry lint free
rag.
5. Install the dipstick making sure
it is fully seated in the filler tube.
6. Remove the dipstick and inspect
the fluid level. The fluid level
should be in the crosshatched area
on the dipstick.DON'T ADD IF IN CROSSHATCHED AREA • CHECK WHEN HOT IDLING IN PARK

7. If necessary, add fluid in .25L
(1/2 pint) increments through the
filler tube until the level is correct.
8. If an overfill occurs, excess fluid
should be removed by a qualified
technician.
An overfill condition of
transmission fluid may cause
shift and/or engagement
concerns and/or possible
damage.
If the fluid level is above the top
notch of the hot range after driving
the vehicle for approximately 30
km (20 miles), excess fluid should
be removed by a qualified
technician.
DRIVELINE UNIVERSAL JOINT
AND SLIP YOKE
The universal joints standard with
your vehicle do not require
lubrication. If the original universal
joints are replaced with universal
joints equipped with grease
fittings, lubrication will be
necessary.
