CONNECTING A TRAILER
PRECAUTIONS
WARNING: Do not adjust the spring
bars so that your vehicle's rear bumper
is higher than before attaching the trailer.
Doing so will defeat the function of the
weight-distributing hitch, which may
cause unpredictable handling, and could
result in serious personal injury.
Do not tow a trailer until you drive your
vehicle at least 1,000 mi (1,600 km).
Do not use a hitch that either clamps onto
the bumper or attaches to the axle. You
must distribute the load in your trailer so
that 10-15% of the total weight of the
trailer is on the trailer coupler.
Consult your local motor vehicle laws for
towing a trailer.
See the instructions included with towing
accessories for the proper installation and
adjustment specifications.
Service your vehicle more frequently if you
tow a trailer. See Normal Scheduled
Maintenance (page 605).
If you use a rental trailer, follow the
instructions the rental agency gives you.
When attaching the trailer wiring connector
to your vehicle, only use a proper fitting
connector that works with the vehicle and
trailer functions.
Account for the trailer coupler weight as
part of your vehicle load when calculating
the total vehicle weight.
Do not exceed the load limits. See
Calculating the Load Limit (page 363).
