{CAUTION:
Fans or other moving engine parts can
injure you badly. Keep your hands away
from moving parts once the engine is
running.
5. Check that the jumper cables do not have
loose or missing insulation. If they do, you
could get a shock. The vehicles could
be damaged too.
Before you connect the cables, here are some
basic things you should know. Positive (+)
will go to positive (+) or to a remote positive (+)
terminal if the vehicle has one. Negative (−)
will go to a heavy, unpainted metal engine part
or to a remote negative (−) terminal if the
vehicle has one.
Do not connect positive (+) to negative (−)or
you will get a short that would damage
the battery and maybe other parts too. And do
not connect the negative (−) cable to the
negative (−) terminal on the dead battery
because this can cause sparks.6. Connect the red
positive (+) cable to
the positive (+)
terminal of
the vehicle with the
dead battery.
Use a remote
positive (+) terminal
if the vehicle
has one.
7. Do not let the other end touch metal. Connect
it to the positive (+) terminal of the good
battery. Use a remote positive (+) terminal if
the vehicle has one.
8. Now connect the black negative (−) cable to
the negative (−) terminal of the good battery.
Use a remote negative (−) terminal if the
vehicle has one.
Do not let the other end touch anything until
the next step. The other end of the negative (−)
cable does not go to the dead battery. It
goes to a heavy, unpainted metal engine part
or to the remote negative (−) terminal on
the vehicle with the dead battery.

9. Connect the other end of the negative (−)
cable to the remote negative (−) terminal,
on the vehicle with the dead battery.
10. Now start the vehicle with the good battery
and run the engine for a while.
11. Try to start the vehicle that had the dead
battery. If it will not start after a few tries, it
probably needs service.
Notice:If the jumper cables are connected or
removed in the wrong order, electrical
shorting may occur and damage the vehicle.
The repairs would not be covered by your
warranty. Always connect and remove
the jumper cables in the correct order, making
sure that the cables do not touch each other
or other metal.A. Heavy, Unpainted Metal Engine Part or

To disconnect the jumper cables from both
vehicles do the following:
1. Disconnect the black negative (−) cable from
the vehicle that had the bad battery.
2. Disconnect the black negative (−) cable from
the vehicle with the good battery.
3. Disconnect the red positive (+) cable from the
vehicle with the good battery.
4. Disconnect the red positive (+) cable from the
other vehicle.
5. Return the remote positive (+) terminal cover,
if equipped, to its original position.All-Wheel Drive
Transfer Case
If your vehicle is equipped with All-Wheel Drive,
be sure to perform the lubricant checks described
in this section. There are two additional systems
that need lubrication.
When to Check Lubricant
Refer to the Maintenance Schedule to determine
how often to check the lubricant. SeeScheduled
Maintenance on page 523.
443

Page 444 of 580

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 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 533.
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.(A) Drain Plug (B) Filler Plug
444

Page 445 of 580

All axle assemblies are lled by volume of uid
during production. They are not lled to reach
a certain level. When checking the uid level on
any axle, variations in the readings can be caused
by factory ll differences between the minimum
and the maximum uid volume. Also, if a vehicle
has just been driven before checking the uid
level, it may appear lower than normal because
uid has traveled out along the axle tubes and has
not drained back to the sump area. Therefore, a
reading taken ve minutes after the vehicle
has been driven will appear to have a lower uid
level than a vehicle that has been stationary
for an hour or two. Remember that the rear axle
assembly must be supported to get a true reading.How to Check Lubricant
To get an accurate reading, the vehicle should be
on a level surface.
The proper level is from 0.04 inch to 0.75 inch
(1.0 mm to 19.0 mm) below the bottom of the ller
plug hole, located on the rear axle. Add only
enough uid to reach the proper level.
What to Use
Refer to the Maintenance Schedule to determine
what kind of lubricant to use. SeeRecommended
Fluids and Lubricants on page 533.

Front Axle
When to Check and Change Lubricant
It is not necessary to regularly check front 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.
A:Fill PlugB:Drain PlugIf the level is below the bottom of the ller plug
hole, located on the front axle, you may need
to add some lubricant:
When the differential is cold, add enough
lubricant to raise the level from 0 (0 mm)
to 1/8 inch (3.2 mm) below the ller plug hole.
When the differential is at operating
temperature (warm), 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 533.

Headlamp Aiming
The vehicle has a visual optical headlamp aiming
system. The aim of the headlamps have been
preset at the factory and should need no further
adjustment.
However, if the vehicle is damaged in an accident,
the aim of the headlamps may be affected and
adjustment may be necessary.
If oncoming vehicles ash their high beams at
you, this may mean the vertical aim of your
headlamps needs to be adjusted.
It is recommended that the vehicle is taken to your
dealer for service if the headlamps need to be
adjusted. It is possible however, to re-aim
the headlamps as described in the following
procedure.
The vehicle should be properly prepared as
follows:
The vehicle should be placed so the
headlamps are 25 ft. (7.6 m) from a light
colored wall or other at surface.
The vehicle must have all four tires on a level
surface which is level all the way to the wall
or other at surface.
The vehicle should be placed so it is
perpendicular to the wall or other at surface.
The vehicle should not have any snow, ice, or
mud on it.
The vehicle should be fully assembled and all
other work stopped while headlamp aiming is
being performed.
The vehicle should be normally loaded with a
full tank of fuel and one person or 160 lbs
(75 kg) sitting on the driver’s seat.
Tires should be properly inated.
The spare tire is in its proper 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.
447

To adjust the vertical aim, do the following:
1. Open the hood. SeeHood Release on
page 405for more information.
2. Locate the center of
the projector lens of
the low-beam
headlamp.
3. Measure the distance from the ground to the
center of the projector lens of the low-beam
headlamp. Record the distance.4. At the 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) on the wall
the width of the vehicle at the height of the
mark 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 adjusted. This allows
only the beam of light from the headlamp
being adjusted to be seen on the at surface.
448

7. Locate the vertical headlamp aiming screws,
which are under the hood near each headlamp
assembly.
The adjustment screw can be turned with a E8
Torx
®socket.
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.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.

{CAUTION:
The low beam high intensity discharge
lighting system operates at a very high
voltage. If you try to service any of the
system components, you could be
seriously injured. Have your dealer or a
qualied technician service them.
Your vehicle has HID headlamps. After your
vehicle’s HID headlamp bulb has been replaced,
you may notice that the beam is a slightly different
shade than it was originally. This is normal.
