TRAILER TOWING

may require the use of a trailer
tow option package.
Trailer towing puts additional loads
on your vehicle's engine,
transmission, axle, brakes, tires,
and suspension. For your safety
and to maximize vehicle
performance, be sure to use the
proper equipment while towing.
Follow these guidelines to ensure
safe towing procedure:
²Stay within your vehicle's load
limits.
²Thoroughly prepare your vehicle
for towing. Refer toPreparing
to towin this chapter.
²Use extra caution when driving
while trailer towing. Refer to

chapter.
²Service your vehicle more
frequently if you tow a trailer.
Refer to the severe duty
schedule in the ªService Guideº.
²Do not tow a trailer until your
vehicle has been driven at least
800 km (500 miles).
