{CAUTION:
If you let your tires spin at high speed, they
can explode, and you or others could be
injured. And, the transmission or other parts of
the vehicle can overheat. That could cause an
engine compartment ®re or other damage.
When you're stuck, spin the wheels as little as
possible. Don't spin the wheels above 35 mph
(55 km/h) as shown on the speedometer.
Notice:Spinning your wheels can destroy parts of
your vehicle as well as the tires. If you spin the
wheels too fast while shifting your transmission
back and forth, you can destroy your transmission.
For information about using tire chains on your
vehicle, see
Tire Chains on page 5-68.
Rocking Your Vehicle To Get It Out
First, turn your steering wheel left and right. That will
clear the area around your front wheels. If you have a
four-wheel-drive vehicle, shift into 4HI or 4LO. If
your vehicle has the Traction Assist System, you should
turn it off by pressing the TAS on/off button. If your
vehicle has the Stabilitrak
žSystem, turn the system off
by pressing the Stabilitrakžbutton so that the
STABILITY SYS DISABLED message and the traction
off light are illuminated on the instrument panel
cluster. Then shift back and forth between
REVERSE (R) and a forward gear, spinning the wheels
as little as possible. Release the accelerator pedal
while you shift, and press lightly on the accelerator pedal
when the transmission is in gear. By slowly spinning
your wheels in the forward and reverse directions, you
will cause a rocking motion that may free your
vehicle. If that doesn't get you out after a few tries, you
may need to be towed out. Or, you can use your
recovery hooks if your vehicle has them. If you do need
to be towed out, see
Towing Your Vehicle on
page 4-48.

Towing
Towing Your Vehicle
Consult your dealer or a professional towing service if
you need to have your disabled vehicle towed. See
Roadside Assistance Program on page 7-6.
If you want to tow your vehicle behind another vehicle
for recreational purposes (such as behind a motorhome),
see ªRecreational Vehicle Towingº following.
Recreational Vehicle Towing
Recreational vehicle towing means towing your vehicle
behind another vehicle ± such as behind a motorhome.
The two most common types of recreational vehicle
towing are known as ªdinghy towingº (towing your
vehicle with all four wheels on the ground) and ªdolly
towingº (towing your vehicle with two wheels on
the ground and two wheels up on a device known as a
ªdollyº).With the proper preparation and equipment, many
vehicles can be towed in these ways. See ªDinghy
Towingº and ªDolly Towing,º following.
Here are some important things to consider before you
do recreational vehicle towing:
·What's the towing capacity of the towing vehicle?
Be sure you read the tow vehicle manufacturer's
recommendations.
·How far will you tow? Some vehicles have
restrictions on how far and how long they can tow.
·Do you have the proper towing equipment?
See your dealer or trailering professional for
additional advice and equipment recommendations.
·Is your vehicle ready to be towed? Just as you
would prepare your vehicle for a long trip, you'll
want to make sure your vehicle is prepared to be
towed. See
Before Leaving on a Long Trip on
page 4-38.
4-48

Dinghy Towing
Two-Wheel-Drive Vehicles
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. To properly tow these vehicles,
they should be placed on a platform trailer with all four
wheels off the ground.
Four-Wheel-Drive Vehicles
Use the following procedure to correctly tow you vehicle
on all four wheels:
1. Firmly set the parking brake.
2. Shift the transmission to PARK (P).
3. Securely attach the vehicle being towed to the tow
vehicle.
{CAUTION:
Shifting the transfer case to NEUTRAL can
cause your vehicle to roll even if the
transmission is in PARK (P). You or someone
else could be seriously injured. Be sure to set
the parking brake before placing the transfer
case in NEUTRAL. See ªParking Brakeº in the
Index.
4. Shift the transfer case to NEUTRAL (N). See
Four-Wheel Drive on page 2-34for the proper
procedure to select the neutral position for your
vehicle.
4-49

5. Release the parking brake only after the vehicle
being towed is ®rmly attached to the towing
vehicle.
6. When the vehicle is properly attached to the tow
vehicle and is ready to be towed, turn the ignition
to LOCK.
Dolly Towing
Two-Wheel-Drive Vehicles
Two-wheel-drive vehicles should not be towed with the
rear wheels on the ground. Two-wheel-drive
transmission have no provisions for internal lubrication
while being towed. To properly tow these vehicles,
they should be placed on a platform trailer with all four
wheels off the ground.
Four-Wheel-Drive Vehicles
Use the following procedure to correctly tow you vehicle
on two wheels:
1. Firmly set the parking brake.
2. Shift the transmission to PARK (P).
3. Securely attach the vehicle being towed to the tow
vehicle.
4-50

{CAUTION:
Shifting the transfer case to NEUTRAL can
cause your vehicle to roll even if the
transmission is in PARK (P). You or someone
else could be seriously injured. Be sure to set
the parking brake before placing the transfer
case in NEUTRAL. See ªParking Brakeº in the
Index.
4. Shift the transfer case to NEUTRAL (N). See
Four-Wheel Drive on page 2-34for the proper
procedure to select the neutral position for your
vehicle.
5. Release the parking brake only after the vehicle
being towed is ®rmly attached to the towing
vehicle.
6. When the vehicle is properly attached to the tow
vehicle and is ready to be towed, turn the ignition
to LOCK.
Loading Your Vehicle
The Certi®cation/Tire label is found on the rear edge of
the driver's door.
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 GVWR (Gross
Vehicle Weight Rating). The GVWR includes the
weight of the vehicle, all occupants, fuel and cargo.
4-51

Trailer Recommendations
You must subtract your hitch loads from the Cargo
Weight Rating (CWR). CWR is the maximum weight of
the load your vehicle can carry. It doesn't include
the weight of the people inside. But you can ®gure about
150 lbs. (68 kg) for each seat. The total cargo load
must not be more than your vehicle's CWR.
Weigh your vehicle with the trailer attached, so that you
won't go over the GVWR or GAWR. If you are using
a weight-distributing hitch, weigh the vehicle without the
spring bars in place.
You'll get the best performance if you spread out the
weight of your load the right way, and if you choose the
correct hitch and trailer brakes.
For more information, see
Towing a Trailer on
page 4-58.
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 -- 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.
To identify the vehicle trailering capacity of your vehicle,
you should read the information in ªWeight of the
Trailerº that appears later in this section.
4-58

·Will you have to make any holes in the body of
your vehicle when you install a trailer hitch?
If you do, then be sure to seal the holes later when
you remove the hitch. If you don't seal them,
deadly carbon monoxide (CO) from your exhaust
can get into your vehicle. See²Carbon Monoxide²in
the Index. Dirt and water can, too.
Safety Chains
You should always attach chains between your vehicle
and your trailer. Cross the safety chains under the
tongue of the trailer to help prevent the tongue from
contacting the road if it becomes separated from
the hitch. Always leave just enough slack so you can
turn with your rig. Never allow safety chains to drag on
the ground.
Trailer Brakes
If your trailer weighs more than 2,000 lbs. (900 kg)
loaded, then it needs its own brakes ± and they must be
adequate. Be sure to read and follow the instructions
for the trailer brakes so you'll be able to install,
adjust and maintain them properly.Your trailer brake system can tap into the vehicle's
hydraulic brake system only if:
·The trailer parts can withstand 3,000 psi (20 650
kPa) of pressure.
·The trailer's brake system will use less than 0.02
cubic inch (0.3 cc) of ¯uid from your vehicle's
master cylinder. Otherwise, both braking systems
won't work well. You could even lose your brakes.
·Your vehicle is not equipped with Stabilitrakž.
If everything checks out this far, make the brake tap at
the port on the master cylinder that sends the ¯uid
to the rear brakes. But don't use copper tubing for this.
If you do, it will bend and ®nally break off. Use steel
brake tubing.
Driving with a Trailer
Towing a trailer requires a certain amount of experience.
Before setting out for the open road, you'll want to get
to know your rig. Acquaint yourself with the feel of
handling and braking with the added weight of the trailer.
And always keep in mind that the vehicle you are
driving is now a good deal longer and not nearly as
responsive as your vehicle is by itself.
