When Towing a Trailer
Do not drive faster than 70 mph
(113 km/h) during the first 500 mi
(800 km).
Do not make full-throttle starts.
Check your hitch, electrical connections
and trailer wheel lug nuts thoroughly
after you have traveled 50 mi (80 km).
When stopped in congested or heavy
traffic during hot weather, place the
gearshift in position P to aid engine and
transmission cooling and to help A/C
performance.
Switch off the speed control with
heavy loads or in hilly terrain. The
speed control may turn off
automatically when you are towing on
long, steep grades.
Shift to a lower gear when driving down
a long or steep hill. Do not apply the
brakes continuously, as they may
overheat and become less effective.
If your transmission is equipped with a
Grade Assist or Tow/Haul feature, use
this feature when towing. This provides
engine braking and helps eliminate
excessive transmission shifting for
optimum fuel economy and
transmission cooling.
If your vehicle is equipped with
AdvanceTrac with RSC, this system
may turn on during typical cornering
maneuvers with a heavily loaded trailer.
This is normal. Turning the corner at a
slower speed while towing may reduce
this tendency.
If you are towing a trailer frequently in
hot weather, hilly conditions, at the
gross combined weight rating (or any
combination of these factors), consider
refilling your rear axle with synthetic
gear lubricant. See Capacities and
Specifications (page 219).
Allow more distance for stopping with
a trailer attached. Anticipate stops and
brake gradually.
Avoid parking on a grade. However, if
you must park on a grade:
1. Turn the steering wheel to point your
vehicle tires away from traffic flow.
2. Set your vehicle parking brake.
3. Place the automatic transmission in
position P.
4. Place wheel chocks in front and back
of the trailer wheels. (Chocks not
included with vehicle.)
Your vehicle may be equipped with a
temporary or conventional spare tire. A
"temporary" spare tire is different in size
(diameter or width), tread-type
(All-Season or All Terrain) or is from a
different manufacturer than the road tires
on your vehicle. Consult information on the
tire label or Safety Compliance label for
limitations when using.
Launching or Retrieving a Boat or
Personal Watercraft (PWC)
Note: Disconnect the wiring to the trailer
before backing the trailer into the water.
Note: Reconnect the wiring to the trailer
after removing the trailer from the water.
When backing down a ramp during boat
launching or retrieval:
Do not allow the static water level to
rise above the bottom edge of the rear
bumper.
Do not allow waves to break higher
than 6 in (15 cm) above the bottom
edge of the rear bumper.
