ESSENTIAL TOWING CHECKS
Follow these guidelines for safe towing:
•
Do not tow a trailer until you drive your
vehicle at least 1,000 mi (1,600 km).
• 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 Scheduled
Maintenance (page 168).
• If you use a rental trailer, follow the
instructions the rental agency gives
you.
Another chapter of this manual contains
load specification terms found on the tire
label and Safety Compliance label and
instructions on calculating your vehicle's
load. See
Load Limit (page 78).
Remember to account for the trailer
tongue weight as part of your vehicle load
when calculating the total vehicle weight.
Hitches
Do not use a hitch that either clamps onto
the bumper or attaches to the axle.
Distribute the trailer load so 10-15% of the
total trailer weight is on the tongue.
Weight-Distributing Hitches 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. When hooking-up a trailer using a
weight-distributing hitch, always use the
following procedure:
1. Park the loaded vehicle, without the
trailer, on a level surface.
2. Measure the height to the top of your vehicle ’s front wheel opening on the
fender. This is H1.
3. Securely attach the loaded trailer to your vehicle without the
weight-distributing bars connected.
4. Measure the height to the top of your vehicle ’s front wheel opening on the
fender a second time. This is H2.
5. Install and adjust the tension in the weight-distributing bars so that the
height of your vehicle ’s front wheel
opening on the fender is approximately
halfway between H1 and H2.
6. Check that the trailer is level or slightly
nose down toward your vehicle. If not,
adjust the ball height accordingly and
repeat Steps 1-6.
7. Lock the bar tension adjuster in place.
8. Check that the trailer tongue securely attaches and locks onto the hitch.
9. Install safety chains, lighting and trailer
brake controls as required by law or the
trailer manufacturer.
Safety Chains
Note: Never attach safety chains to the
bumper.
Always connect the safety chains to the
hook retainers of your vehicle hitch.
To connect the safety chains, cross them
under the trailer tongue and allow enough
slack for turning tight corners. Do not allow
the chains to drag on the ground.
