All-Wheel Drive
If your vehicle is equipped with all-wheel-drive, this is an
additional system that needs lubrication.
Transfer Case
When to Check Lubricant
It is not necessary to regularly check the transfer case
uid unless you suspect there is a leak or you hear
an unusual noise. A uid loss could indicate a problem.
Have it inspected and repaired. Jumper Cable Removal
5-51

How to Check Lubricant
A. Drain Plug
B. Fill Plug
To get an accurate reading, the vehicle should be on a
level surface.
If the level is below the bottom of the ller plug hole,
located on the transfer case, you’ll need to add
some lubricant. Add enough lubricant to raise the level
to the bottom of the ller plug hole. Use care not to
overtighten the plug.
What to Use
Refer to the Maintenance Schedule to determine what
kind of lubricant to use. SeeRecommended Fluids
and Lubricants on page 6-14.
Rear Axle
When to Check Lubricant
It is not necessary to regularly check rear axle uid
unless you suspect there is a leak or you hear an
unusual noise. A uid loss could indicate a problem.
Have it inspected and repaired.

How to Check Lubricant
To get an accurate reading, the vehicle should be on a
level surface.
If the level is below the bottom of the ller plug hole,
located on the rear axle, you’ll need to add some
lubricant. Add enough lubricant to raise the level to the
bottom of the ller plug hole.
What to Use
Refer to the Maintenance Schedule to determine what
kind of lubricant to use. SeeRecommended Fluids
and Lubricants on page 6-14.
Headlamp Aiming
The vehicle has a visual optical headlamp aiming
system. The aim has been preset at the factory and
should need no further adjustment.
However, if the vehicle is damaged in a crash, the
headlamp aim may be affected and adjustment may be
necessary.
If oncoming vehicles ash their high beams at you, this
may also mean the vertical aim needs to be adjusted.
5-53

It is recommended that the vehicle is taken to your
dealer/retailer for service if the headlamps need to be
re-aimed. It is possible however, to re-aim the
headlamps as described.
The vehicle should:
Be placed so the headlamps are 25 ft. (7.6 m) from
a light colored wall.
Have all four tires on a level surface which is level
all the way to the wall.
Be placed so it is perpendicular to the wall.
Not have any snow, ice, or mud on it.
Be fully assembled and all other work stopped while
headlamp aiming is being performed.
Normally loaded with a full tank of fuel and
one person or 160 lbs (75 kg) sitting on the
driver seat.
Have all tires properly inated.
If your vehicle has a spare tire, ensure the spare
tire is in its original location in the vehicle.
Headlamp aiming is done with the vehicle’s low-beam
headlamps. The high-beam headlamps will be correctly
aimed if the low-beam headlamps are aimed properly.To adjust the vertical aim:
1. Open the hood. SeeHood Release on page 5-12
for more information.
Halogen Headlamps
5-54

2. Locate the aim dot on the lens of the low-beam
headlamp.
3. Record the distance from the ground to the aim dot
on the low-beam headlamp.4. At a wall, measure from the ground upward (A) to
the recorded distance from Step 3 and mark it.
5. Draw or tape a horizontal line (B) the width of the
vehicle at the wall where it was marked in Step 4.
Notice:Do not cover a headlamp to improve beam
cut-off when aiming. Covering a headlamp may
cause excessive heat build-up which may cause
damage to the headlamp.
6. Turn on the low-beam headlamps and place a piece
of cardboard or equivalent in front of the headlamp
not being aimed. This should allow only the beam of
light from the headlamp being aimed to be seen on
the at surface. High Intensity Discharge Headlamps
5-55

7. Locate the vertical headlamp aiming screws, which
are under the hood near each headlamp assembly.
They are covered by a rubber caps.
The adjustment screw can be turned with a
6 mm hex driver.
8. Turn the vertical aiming screw until the headlamp
beam is aimed to the horizontal tape line. Turn it
clockwise or counterclockwise to raise or lower the
angle of the beam.
The top edge of the cut-off should be positioned at
the bottom edge of the horizontal tape line.9. Make sure that the light from the headlamp is
positioned at the bottom edge of the horizontal tape
line. The lamp on the left (A) shows the correct
headlamp aim. The lamp on the right (B) shows the
incorrect headlamp aim.
10. Repeat Steps 7 through 9 for the opposite
headlamp. Driver Side Shown

service any of the system components, you could
be seriously injured. Have your dealer/retailer or a
qualied technician service them.The vehicle may have HID headlamps. After the
vehicle’s HID headlamp bulb has been replaced, you
