Dinghy Towing
Vehicles with the Automatic Transfer Case
If your vehicle is equipped with an automatic transfer
case with a NEUTRAL position, you can dinghy tow your
vehicle. To dinghy tow your vehicle, use the following
steps:
1. Firmly set the parking brake.
2. Place the transmission in PARK (P).3. 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.
4. With the engine running, shift the transfer case to
NEUTRAL (N). See ªAutomatic Transfer Caseº
under
Four-Wheel Drive on page 5-45for more
information on how to shift the transfer case
to NEUTRAL.
4-46

5. Release the parking brake only after the vehicle
being towed is ®rmly attached to the towing
vehicle.
Notice:Make sure that the towing speed does not
exceed 55 mph (90 km/h), or your vehicle could
be badly damaged.
Notice:Do not exceed the posted speed limit when
towing your vehicle. If you do, your vehicle could
be badly damaged.
6. Turn the ignition to OFF. 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. See
Fuses and Circuit
Breakers on page 5-85.
Dinghy Towing (Two-Wheel Drive
Vehicles and Vehicles with the Electronic
Transfer Case)
Notice:Towing your vehicle with all four wheels on
the ground will damage drivetrain components.
Two-wheel drive and four-wheel drive vehicles with the
electronic transfer case should not be towed with all
four wheels on the ground. Your transmission has
no provision for internal lubrication while being towed.
To properly tow your vehicle, it should be placed
on a platform trailer with all four wheels off the ground.

Dolly Towing (Vehicles with Automatic
Transfer Case)
If your vehicle has an automatic transfer case, your
vehicle should not be dolly towed. Your automatic
transfer case vehicle should be either dinghy towed or
placed on a platform trailer with all four wheels off
the ground. See ªDinghy Towingº previously for further
instructions.

Loading Your Vehicle
The Certi®cation/Tire label is found on the driver's door
edge, above the door latch.The label shows the size of your original tires and the
in¯ation pressures needed to obtain the gross weight
capacity of your vehicle. This is called the Gross Vehicle
Weight Rating (GVWR). The GVWR includes the
weight of the vehicle, all occupants, fuel, cargo and
trailer tongue weight, if pulling a trailer.
The Certi®cation/Tire label also tells you the maximum
weights for the front and rear axles, called Gross
Axle Weight Rating (GAWR). To ®nd out the actual loads
on your front and rear axles, you need to go to a
weigh station and weigh your vehicle. Your dealer can
help you with this. Be sure to spread out your load
equally on both sides of the centerline.
Never exceed the GVWR for your vehicle, or the GAWR
for either the front or rear axle.
If you do have a heavy load, you should spread it out.
Similar appearing vehicles may have different GVWRs
and payloads. Please note your vehicle's
Certi®cation/Tire label or consult your dealer for
additional details.
4-52

Payload
This is the maximum load capacity that your vehicle can
carry. Be sure to include the weight of the occupants
as part of your load. If you added any accessories
or equipment after your vehicle left the factory,
remember to subtract the weight of these things from
the payload. Your dealer can help you with this.
Add-On Equipment
When you carry removable items, you may need to put
a limit on how many people you carry inside your
vehicle. Be sure to weigh your vehicle before you buy
and install the new equipment.
Notice:Your warranty does not cover parts or
components that fail because of overloading.
Towing a Trailer
{CAUTION:
If you don't use the correct equipment and
drive properly, you can lose control when you
pull a trailer. For example, if the trailer is too
heavy, the brakes may not work well Ð or
even at all. You and your passengers could be
seriously injured. Pull a trailer only if you have
followed all the steps in this section. Ask your
dealer for advice and information about towing
a trailer with your vehicle.
Notice:Pulling a trailer improperly can damage
your vehicle and result in costly repairs not covered
by your warranty. To pull a trailer correctly, follow
the advice in this part, and see your dealer for
important information about towing a trailer with
your vehicle. Additional rear axle maintenance
is required for a vehicle used to tow a trailer. See
ªScheduled Maintenance Servicesº in the Index.
To identify what the vehicle trailering capacity is for your
vehicle, you should read the information in ªWeight of
the Trailerº that appears later in this section.
4-54

If yours was built with trailering options, as many are,
it's ready for heavier trailers. But trailering is different
than just driving your vehicle by itself. Trailering means
changes in handling, durability and fuel economy.
Successful, safe trailering takes correct equipment, and
it has to be used properly.
That's the reason for this part. In it are many time-tested,
important trailering tips and safety rules. Many of
these are important for your safety and that of your
passengers. So please read this section carefully before
you pull a trailer.
If You 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 if your trailer will
weigh 3,500 lbs. (1 589 kg) or less. You should
always use a sway control if your trailer will weigh
more than 3,500 lbs. (1 589 kg). 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.
·If you have an automatic transmission, you can tow
in DRIVE (D). 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. See
Tow/Haul Mode Light on page 3-35.
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.
4-55

Tow/Haul Mode
Your vehicle may be equipped with a tow/haul feature.
The tow/haul mode is a feature that assists when
pulling a heavy trailer. The purpose of the tow/haul
mode is:
·Reduce the frequency of shifts when pulling a
heavy trailer,
·provide the same shift feel when pulling a heavy
trailer as when the vehicle is unloaded, and
·reduce the need to change throttle position when
pulling a heavy trailer.
This feature is turned on or off by pressing a button on
the ¯oor console or the shift knob. When the feature
is on, a light located on the instrument panel cluster will
illuminate to indicate that the tow/haul mode has
been selected.
See
Tow/Haul Mode Light on page 3-35. The tow/haul
mode is automatically turned off each time the vehicle is
started.
The tow/haul mode is most effective when the vehicle
and trailer combined weight is at least 75% of the Gross
Combination Weight Rating (GCWR).The tow/haul mode for hauling a heavy trailer is most
useful under the following conditions:
·When driving through hilly terrain at speeds below
55 mph (88 km/h),
·when driving in low speed or stop and go traffic
below 55 mph (88 km/h), and
·when driving in parking lots.
Operating in the tow/haul mode when not pulling a
heavy trailer will not cause damage to the vehicle, but
you may experience reduced fuel economy and
undesirable performance from the engine and
transmission. The tow/haul mode should be used only
when pulling a heavy trailer.
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.
