Tie a red cloth to your vehicle to alert police that
you've been stopped by the snow.

Put on extra clothing or wrap a blanket around you.
If you have no blankets or extra clothing, make body
insulators from newspapers, burlap bags, rags, floor
mats
-- anything you can wrap around yourself or
tuck under your clothing to keep warm.
You can run the engine to keep warm, but be careful.
CAUTION:
Snow can trap exhaust gases under your vehicle.
This can cause deadly CO (carbon monoxide) gas
to get inside. CO could overcome you and kill
you. You can't see it or smell it, so you might not
know it is in your vehicle. Clear away snow from
around the base of your vehicle, especially any
that is blocking your exhaust pipe. And check
around again from time to time to be sure snow
doesn't collect there.
Open a window just a little on the side of the
vehicle that's away from the wind. This will help
keep CO out.
Run your engine only as long as you must. This saves
fuel. When you run the engine, make it go a little faster
than just idle. That is, push the accelerator slightly. This
uses less fuel for the heat that you get and it keeps the
battery charged. You will need a well
-charged battery to
restart the vehicle, and possibly for signaling later on
with your headlamps. Let the heater run for a while.

Your vehicle has a visual optical headlamp aiming system
equipped with horizontal aim indicators. The aim has
been pre
-set at the factory and should need no further
adjustment. This is true even though your horizontal aim
indicators may not fall exactly on the ª0º (zero) marks on
their scales.

If your vehicle is damaged in an accident, the headlamp
aim may be affected. Aim adjustment to the low beam
may be necessary if it is difficult to see lane markers
(for horizontal aim), or if oncoming drivers flash their
high beams at you (for vertical aim). If you believe your
headlamps need to be re
-aimed, we recommend that you
take your vehicle to your dealer for service. However, it
is possible for you to re
-aim your headlamps as
described in the following procedure.
NOTICE:
To make sure your headlamps are aimed
properly, read all the instructions before
beginning. Failure to follow these instructions
could cause damage to headlamp parts.
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
flat surface.

The vehicle must have all four tires on a perfectly
level surface which is level all the way to the wall or
other flat surface.

The vehicle should be placed so it is perpendicular to
the wall or other flat surface.

The vehicle should not have any snow, ice or mud
attached to it.

The vehicle should be fully assembled and all other
work stopped while headlamp aiming is being done.

The vehicle should be normally loaded with a full
tank of fuel and one person or 160 lbs. (75 kg) on
the driver's seat.

Tires should be properly inflated.
Headlamp aiming is done with the vehicle low beam
lamps. The high beam lamps will be correctly aimed if
the low beam lamps are aimed properly.
The headlamp aiming devices are under the hood near
the headlamps.

If you believe your headlamps need horizontal
(left/right) adjustment, follow the horizontal aiming
procedure. If you believe your headlamps need only
vertical (up/down) adjustment, follow only the vertical
aiming procedure.
Adjustment screws can be turned with an E8 Torx


socket or T15 Torx screwdriver.Headlamp Horizontal Aiming
Turn the horizontal aiming screw (A) until the indicator
(B) is lined up with zero.
Once the horizontal aim is adjusted, then adjust the
vertical aim.

Headlamp Vertical Aiming
1. Find the aim dot on the lens of the lamps.
2. Measure the distance from the ground to the aim dot
on each lamp; if left low beam, subtract two inches.
Record this distance.3. At the wall or other flat surface, measure from the
floor to the recorded distance and draw a horizontal
line the width of the vehicle.

4. Turn on the low beam headlamps and cover the lamp
not being evaluated. The ambient light should allow
the beam cut off to be seen on the wall.5. Turn the vertical aiming screw (C) until the
headlamp beam is aimed to the horizontal line. It is
recommended to cover the lamp that is not being
evaluated to better see the beam being aimed.

Once the headlamp assembly has been removed from
the vehicle, the front turn signal bulbs can be accessed.
1. Reach down into the space provided by the removal
of the headlamp assembly and, while pushing in the

counterclockwise and remove it.
2. Remove the old bulb by pulling it straight out
of the retainer.
3. Replace the bulb and turn the bulb assembly
back into place.
Cornering Lamps
Follow the same procedure as used for replacing the
headlamps. However, to remove the cornering lamp
bulb, press the tab on the bulb assembly while turning
the bulb assembly counterclockwise. Pull the bulb
straight out. Replace the bulb and turn the bulb assembly
back into place.
