3. Disconnect the red positive (+) cable from thevehicle with the good battery.

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 a crash, the aim
of the headlamps may be affected and adjustment may
be necessary.
If oncoming vehicles flash 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.
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.
.Be 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 inflated.
.Have the spare tire is in its proper location in the
vehicle.

Tire Inspection and Rotation
We recommend that you regularly inspect your
vehicle's tires, including the spare tire, for signs of
wear or damage. SeeWhen It Is Time for New
Tires
on page 6‑71for more information.
Always remove the tires if any of the following
statements are true:
.You can see the indicators at three or more
places around the tire.
.You can see cord or fabric showing through
the tire's rubber.
.The tread or sidewall is cracked, cut,
or snagged deep enough to show cord or
fabric.
.The tire has a bump, bulge, or split.
.The tire has a puncture, cut, or other damage
that cannot be repaired well because of the
size or location of the damage.
Tires should be rotated every 12 000 km
(7,500 miles). See Scheduled Maintenance
on
page 7‑3
. The purpose of a regular tire rotation is to achieve
a uniform wear for all tires on the vehicle. This will
ensure that your vehicle continues to perform
most like it did when the tires were new.
Any time you notice unusual wear, rotate the
tires as soon as possible and check wheel
alignment. Also check for damaged tires or
wheels. See
When It Is Time for New Tires
on
page 6‑71
and Wheel Replacementon page 6‑76.
When rotating the vehicle's tires, always use the
correct rotation pattern shown here.
Do not include the compact spare tire in the tire
rotation.

Tire Sealant and Compressor Kit
{WARNING:
Idling a vehicle in an enclosed area with poor
ventilation is dangerous. Engine exhaust may
enter the vehicle. Engine exhaust contains
Carbon Monoxide (CO) which cannot be seen
or smelled. It can cause unconsciousness and
even death. Never run the engine in an enclosed
area that has no fresh air ventilation. For more
information, seeEngine Exhaust on page 3‑30.
{WARNING:
Overinflating a tire could cause the tire to
rupture and you or others could be injured. Be
sure to read and follow the tire sealant and
compressor kit instructions and inflate the tire to
its recommended pressure. Do not exceed the
recommended pressure.
{WARNING:
Storing the tire sealant and compressor kit or
other equipment in the passenger compartment of
the vehicle could cause injury. In a sudden stop or
collision, loose equipment could strike someone.
Store the tire sealant and compressor kit in its
original location.
If this vehicle has a tire sealant and compressor kit,
there may not be a spare tire, tire changing equipment,
and on some vehicles there may not be a place to store
a tire.
The tire sealant and compressor can be used to
temporarily seal punctures up to 6 mm (¼ in) in the
tread area of the tire. It can also be used to inflate an
under inflated tire.
If the tire has been separated from the wheel, has
damaged sidewalls, or has a large puncture, the tire
is too severely damaged for the tire sealant and
compressor kit to be effective. See Roadside
Assistance Program on page 8‑7.
