Preparing to tow
Use the proper equipment for
towing a trailer, and make sure it
is properly attached to your
vehicle. See your dealer or a
reliable trailer dealer if you require
assistance.
Hitches
Do not use or install hitches that
clamp onto the bumper or to the
axle. Underbody hitches are
acceptable if installed properly.
The rear bumper has an integral
hitch and only requires a ball with
a 3/4 inch shank diameter. The

Servicing while towing
If you tow a trailer for long
distances, your vehicle will require
more frequent service intervals.
Refer to theService Guidefor
more information.
Trailer towing
²Practice turning, stopping and
backing in an area before
starting on a trip to get the feel
of the vehicle/trailer
combination. When turning,
drive slightly beyond the normal
turning point so the trailer
wheels will clear curbs and
other obstacles.
²Allow more room for stopping
with a trailer attached.
²The trailer tongue weight should
be 10-15% of the loaded trailer
weight for a Class I or II rear
bumper hitch.
²After you have travelled about
80 km (50 miles), thoroughly
check your hitch, electrical
connections and trailer wheel
lug nuts.
²When stopped in traffic for long
periods of time in hot weather,
place the gearshift in P (Park)
to increase idle speed. This aids
engine cooling and air
conditioner efficiency.
²Vehicles with trailers should not
be parked on a grade. If you
must park on a grade, place
wheel chocks under the trailer's
wheels.

To avoid damage or injury,
follow these directions in
the order they are given. If in
doubt, call for road service.
Before jump starting a vehicle:
²Make sure the booster battery
vehicle has a 12-volt starting
system (a 24-volt power supply
will cause vehicle damage).
²Park the vehicles close to each
other, but do not allow the
vehicles to touch each other.
²Check to make sure neither
battery is disconnected.
²Remove any excessive corrosion
from the battery terminals.
²Turn on the heater fan in each
vehicle to prevent damage from
voltage surges.
To jump start the vehicle, connect
the jumper cables in the following
order:
1. Disabled battery positive
terminal.
2. Booster battery positive
terminal.
3. Booster battery negative
terminal.

Do not connect the end of
the second cable to the
negative (-) terminal of the
battery to be jumped. A spark
may cause an explosion of the
gases that surround the battery.
5. Start the engine in the vehicle
with the booster battery.
6. Wait a few minutes and start the
engine in the vehicle with the
disabled battery.
7. After a few minutes, the
disabled battery should be
recharged. Disconnect the jumper
cables in reverse order.
Let the vehicle idle for a few
minutes to allow the engine to
relearn the proper idle conditions.
Avoid using unnecessary electrical
accessories for a short while to let
the battery fully recharge. A
battery charger may need to be
used to fully recharge the battery.
