• Be certain your rearview mirrors conformto all federal, state or local regulations. If
not, install any mirrors required for towing
before driving the vehicle.
• Determine the overall height of the ve- hicle and trailer so the required clearance
is known.
Trailer towing tips
In order to gain skill and an understanding
of the vehicle's behavior, you should prac-
tice turning, stopping and backing up in
an area which is free from traffic. Steering
stability and braking performance will be
somewhat different than under normal
driving conditions.
• Always secure items in the trailer to pre-vent load shif t while driving.
• Lock the trailer hitch coupler with a pin or lock to prevent the coupler from inadver-
tently becoming unlatched.
• Avoid abrupt starts, acceleration or stops.
• Avoid sharp turns or lane changes.
• Always drive your vehicle at a moderate speed. • When backing up, hold the bottom of the
steering wheel with one hand. Move your
hand in the direction in which you want
the trailer to go. Make small corrections
and back up slowly. If possible, have
someone guide you when you are back-
ing up.
Always block the wheels on both vehicle
and trailer when parking. Parking on a
slope is not recommended; however, if you
must do so:
CAUTION
If you move the shif t selector to the P
(Park) position before blocking the
wheels and applying the parking brake,
transmission damage could occur.
1. Apply and hold the brake pedal.
2. Have someone place blocks on the downhill side of the vehicle and trailer
wheels.
3. Af ter the wheel blocks are in place, slowly release the brake pedal until the
blocks absorb the vehicle load.
4. Apply the parking brake.
5. Shif t the transmission into P (Park). 6. Make sure the
indicator light (if so
equipped) indicates the transfer case is
in 4H, 4LO, or 2H and that the ATP light is
off. If the
indicator light is flashing,
or the ATP light is ON, make sure the
transmission is in P (Park) (A/T) and turn
the 4WD switch to 2WD or 4H. For addi-
tional information, see “Automatic
transmission park warning light” (P. 2-13)
and “Using 4-wheel drive (4WD)” (P. 5-105).
7. Turn off the engine.
To drive away:
1. Start the vehicle.
2. Apply and hold the brake pedal.
3. Shif t the transmission into gear.
4. Release the parking brake.
5. Drive slowly until the vehicle and trailer are clear from the blocks.
6. Apply and hold the brake pedal.
7. Have someone retrieve and store the blocks.
