Dinghy Towing
Two-Wheel Drive Vehicles
Notice:If you tow your vehicle with all four wheels
on the ground, the drivetrain components could
be damaged. The repairs would not be covered by
your warranty. Do not tow your vehicle with all
four wheels on the ground.
Two-wheel-drive vehicles should not be towed with
all four wheels on the ground. Two-wheel-drive
transmissions have no provisions for internal lubrication
while being towed.
Four-Wheel Drive Vehicles
Use the following steps to tow your vehicle with all
four wheels on the ground:
1. Drive the vehicle to be towed into position behind
the tow vehicle.
2. Firmly set the parking brake. SeeParking Brake on
page 2-29for more information.
3. Put an automatic transmission in PARK (P) or a
manual transmission in FIRST (1).
4. Securely attach the vehicle being towed to the
tow vehicle.
{CAUTION:
Shifting a four-wheel-drive vehicle’s transfer
case into NEUTRAL can cause your vehicle to
roll even if the transmission is in Park (P) for
an automatic transmission, or if your vehicle
is in gear, for a manual transmission. You or
others could be injured. Make sure the parking
brake is rmly set before you shift the transfer
case to NEUTRAL.

5. Shift the transfer case to NEUTRAL.
SeeFour-Wheel Drive on page 2-26for
more information.
6. Release the parking brake only after the vehicle
being towed is rmly attached to the towing
vehicle.
Notice:If you exceed 55 mph (90 km/h) while towing
your vehicle, it could be damaged. Never exceed
55 mph (90 km/h) while towing your vehicle.
7. Turn the ignition to LOCK. To prevent your
battery from draining while towing, remove the
RDO BATT and CLSTR fuses from the instrument
panel fuse block. Be sure to replace the fuse
when you reach your destination. SeeFuses and
Circuit Breakers on page 5-104for more information.
After towing see “Shifting out of NEUTRAL” under

If You Do Decide To Pull A Trailer
If you do, here are some important points:
There are many different laws, including speed limit
restrictions, having to do with trailering. Make sure
your rig will be legal, not only where you live
but also where you’ll be driving. A good source for
this information can be state or provincial police.
Consider using a sway control. You can ask a hitch
dealer about sway controls.
Don’t tow a trailer at all during the rst 500 miles
(800 km) your new vehicle is driven. Your engine,
axle or other parts could be damaged.
Then, during the rst 500 miles (800 km) that you
tow a trailer, don’t drive over 50 mph (80 km/h)
and don’t make starts at full throttle. This helps your
engine and other parts of your vehicle wear in at
the heavier loads.
You may want to shift the transmission to THIRD (3)
or, if necessary, a lower gear selection if the
transmission shifts too often (e.g., under heavy
loads and/or hilly conditions). If you have a manual
transmission and you are towing a trailer, it’s
better not to use the highest gear.Three important considerations have to do with weight:
the weight of the trailer,
the weight of the trailer tongue
and the weight on your vehicle’s tires.
Weight of the Trailer
How heavy can a trailer safely be?
It depends on how you plan to use your rig. For example,
speed, altitude, road grades, outside temperature and
how much your vehicle is used to pull a trailer are all
important. And, it can also depend on any special
equipment that you have on your vehicle.
The following chart shows how much your trailer can
weigh, based upon your vehicle model and options.
Maximum trailer weight is calculated assuming only the
driver is in the tow vehicle and it has all the required
trailering equipment. The weight of additional optional
equipment, passengers and cargo in the tow vehicle
must be subtracted from the maximum trailer weight.
The weight of the trailer tongue also affects trailering
capacity. See “Weight of the Trailer Tongue” next.
