feel really uncomfortable from the
cold. Moving about to keep warm
also helps.
If it takes some time for help to
arrive, now and then when you run
the engine, push the accelerator
pedal slightly so the engine runs
faster than the idle speed. This
keeps the battery charged to restart
the vehicle and to signal for help
with the headlamps. Do this as little
as possible to save fuel.
If the Vehicle is Stuck
Slowly and cautiously spin the
wheels to free the vehicle when
stuck in sand, mud, ice, or snow.
If stuck too severely for the traction
system to free the vehicle, turn the
traction system off and use the
rocking method.
{WARNING
If the vehicle's tires spin at high
speed, they can explode, and you
or others could be injured. The
vehicle can overheat, causing an
engine compartment fire or other
damage. Spin the wheels as little
as possible and avoid going
above 55 km/h (35 mph) as
shown on the speedometer.
For information about using tire
chains on the vehicle, see Tire
Chains on page 10‑89.
Rocking the Vehicle to Get
it Out
Turn the steering wheel left and
right to clear the area around the
front wheels. Turn off any traction
system. Shift back and forth
between R (Reverse) and a forward
gear, or with a manual transmission,
between 1 (First) or 2 (Second) and
R (Reverse), spinning the wheels as
little as possible. To prevent transmission wear, wait until the
wheels stop spinning before shifting
gears. Release the accelerator
pedal while shifting, and press
lightly on the accelerator pedal
when the transmission is in gear.
Slowly spinning the wheels in the
forward and reverse directions
causes a rocking motion that could
free the vehicle. If that does not get
the vehicle out after a few tries, it
might need to be towed out. If the
vehicle does need to be towed out,
see
Towing the Vehicle
on
page 10‑117.
Vehicle Load Limits
It is very important to know how
much weight the vehicle can
carry. This weight is called the
vehicle capacity weight and
includes the weight of all
occupants, cargo and all
nonfactory‐installed options.

6. Replace the blade with anew one.
7. Reinstall the wiper bladeassembly by sliding it over the
wiper arm to engage the
J-hooked end. Pull up on the
assembly to lock it into place.
8. Repeat the steps for the other wiper.
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 flash their high
beams at you, this may also mean
the vertical aim needs to be
adjusted.
It is recommended that the vehicle
is taken to your dealer 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
7.6 m (25 ft) 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 have all
other work stopped while
headlamp aiming is being
performed.
.Be loaded with a full tank of fuel
and one person or 75 kg
(160 lbs) sitting on the
driver seat.
.Have all tires properly inflated.
.Have the spare tire (if equipped)
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
on
page 10‑5for more information.

Headlamps
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 theground 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-beamheadlamps 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 flat surface.

7. Locate the vertical headlamp aiming screws, which are under
the hood near each headlamp
assembly. They are covered by
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 theheadlamp 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.

Bulb Replacement
For the proper type of replacement
bulbs, seeReplacement Bulbson
page 10‑40.
For any bulb changing procedure
not listed in this section, contact
your dealer.
Halogen Bulbs
{WARNING
Halogen bulbs have pressurized
gas inside and can burst if you
drop or scratch the bulb. You or
others could be injured. Be sure
to read and follow the instructions
on the bulb package.
High Intensity Discharge
(HID) Lighting
{WARNING
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 qualified technician
service them.
The up‐level vehicle has HID
headlamps. After an HID headlamp
bulb has been replaced, the beam
might be a slightly different shade
than it was originally. This is normal.
Fog Lamps
To replace a front fog lamp bulb:
1. Pull out the push-pins located on the underside of the protection
shield to remove the shield.
2. Reach up behind the front bumper area from under the
vehicle to access the lamp
housing.

Fuses and circuit breakers protect
the following in the vehicle:
.Headlamp Wiring
.Windshield Wiper Motor
.Power Windows and other
Power Accessories
Replace a bad fuse with a new one
of the identical size and rating.
If there is a problem on the road and
a fuse needs to be replaced, the
same amperage fuse can be
borrowed. Choose some feature of
the vehicle that is not needed to use
and replace it as soon as possible.
Headlamp Wiring
An electrical overload may cause
the lamps to go on and off, or in
some cases to remain off. Have the
headlamp wiring checked right away
if the lamps go on and off or
remain off.
Windshield Wipers
If the wiper motor overheats due to
heavy snow or ice, the windshield
wipers will stop until the motor cools
and will then restart. Although the circuit is protected
from electrical overload, overload
due to heavy snow or ice may
cause wiper linkage damage.
Always clear ice and heavy snow
from the windshield before using the
windshield wipers.
If the overload is caused by an
electrical problem and not snow or
ice, be sure to get it fixed.
