3. When the wheel chocks are in place, release thebrake pedal until the chocks absorb the load.
4. Reapply the brake pedal. Then apply the parking brake and shift the transmission into P (Park).
5. Release the brake pedal.
Leaving After Parking on a Hill
1. Apply and hold the brake pedal while you:
.start the engine,
.shift into a gear, and
.release the parking brake.
2. Let up on the brake pedal.
3. Drive slowly until the trailer is clear of the chocks.
4. Stop and have someone pick up and store the chocks.
Maintenance When Trailer Towing
The vehicle needs service more often when pulling a
trailer. See Scheduled Maintenanceon page 7‑3for
more information. Things that are especially important
in trailer operation are automatic transmission fluid,
engine oil, belts, cooling system and brake system. It is
a good idea to inspect these before and during the trip.
Check periodically to see that all hitch nuts and bolts
are tight.
Engine Cooling When Trailer Towing
The cooling system may temporarily overheat during
severe operating conditions. See Engine Overheating
on page 6‑29.
Changing a Tire When Trailer Towing
If the vehicle gets a flat tire while towing a trailer, be
sure to secure the trailer and disconnect it from the
vehicle before changing the tire.

To disconnect the jumper cables from both vehicles, do
the following:1. Disconnect the black negative (−) cable from the vehicle that had the dead 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 to its original position.
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.
Notice:
To make sure the 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 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 original location in the
vehicle.

Tires
Your new vehicle comes with high-quality tires
made by a leading tire manufacturer. If you ever
have questions about your tire warranty and
where to obtain service, see your vehicle
Warranty booklet for details. For additional
information refer to the tire manufacturer.
{WARNING:
.Poorly maintained and improperly used tires
are dangerous.
.Overloading your tires can cause overheating
as a result of too much flexing. You could
have a blowout and a serious accident. See
Loading the Vehicle on page 5‑18.
.Under inflated tires pose the same danger as
overloaded tires. The resulting crash could
cause serious injury. Check all tires frequently
to maintain the recommended pressure. Tire
pressure should be checked when your tires
are cold.(Continued)
WARNING: (Continued)
.Over inflated tires are more likely to be
cut, punctured, or broken by a sudden
impact—such as when you hit a pothole.
Keep tires at the recommended pressure.
.Worn or old tires can cause a crash. If your
tread is badly worn, replace them.
.Replace any tires that have been damaged by
impacts with potholes, curbs, etc.
.Improperly repaired tires can cause a crash.
Only your dealer or an authorized tire service
center should repair, replace, dismount, and
mount the tires.
.Do not spin the tires in excess of 55 km/h
(35 mph) on slippery surfaces such as snow,
mud, ice, etc. Excessive spinning may cause
the tires to explode.
See High-Speed Operation
on page 6‑59for inflation
pressure adjustment for high speed driving.
