Rocking Your Vehicle to Get It Out
First, turn the steering wheel left and right to clear
the area around the front wheels. Turn off any traction
or stability system. SeeTraction Control System
(TCS) on page 4-6,Enhanced Traction System (ETS)
on page 4-7, andStabiliTrak
®Plus System on page 4-8.
Then shift back and forth between REVERSE (R) and
a forward gear, spinning the wheels as little as possible.
To prevent transmission wear, wait until the wheels
stop spinning before shifting gears. Release the
accelerator pedal while you shift, and press lightly on
the accelerator pedal when the transmission is in gear.
By slowly spinning the wheels in the forward and
reverse directions, you will cause a rocking motion
that could free your vehicle. If that does not get
your vehicle out after a few tries, it might need to be
towed out. If your vehicle does need to be towed
out, seeTowing Your Vehicle on page 4-27.
Loading Your Vehicle
It is very important to know how much weight your
vehicle can carry. Two labels on your vehicle show
how much weight it may properly carry, the Tire
and Loading Information label and the Vehicle
Certication label.
{CAUTION:
Do not load your vehicle any heavier than
the Gross Vehicle Weight Rating (GVWR),
or either the maximum front or rear Gross
Axle Weight Rating (GAWR). If you do,
parts on your vehicle can break, and it
can change the way your vehicle handles.
These could cause you to lose control
and crash. Also, overloading can shorten
the life of your vehicle.

4.The resulting gure equals the available
amount of cargo and luggage load capacity.
For example, if the “XXX” amount equals
1400 lbs and there will be ve 150 lb
passengers in your vehicle, the amount of
available cargo and luggage load capacity
is 650 lbs (1400−750 (5 x 150) = 650 lbs).
5.Determine the combined weight of luggage
and cargo being loaded on the vehicle.
That weight may not safely exceed the
available cargo and luggage load capacity
calculated in Step 4.
6.If your vehicle will be towing a trailer, the load
from your trailer will be transferred to your
vehicle. Consult this manual to determine how
this reduces the available cargo and luggage
load capacity for your vehicle.
If your vehicle can tow a trailer, seeTowing a
Trailer on page 4-29for important information
on towing a trailer, towing safety rules, and
trailering tips.Item Description Total

{CAUTION:
Things you put inside your vehicle can
strike and injure people in a sudden stop
or turn, or in a crash.
Put things in the trunk of your vehicle.
In a trunk, put them as far forward
as you can. Try to spread the weight
evenly.
Never stack heavier things, like
suitcases, inside the vehicle so that
some of them are above the tops
of the seats.
Do not leave an unsecured child
restraint in your vehicle.
When you carry something inside the
vehicle, secure it whenever you can.
Do not leave a seat folded down
unless you need to.
Towing
Towing Your Vehicle
Consult your dealer/retailer or a professional towing
service if you need to have your disabled vehicle towed.
SeeRoadside 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 “Recreational Vehicle Towing” 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 dinghy towing, towing your vehicle
with all four wheels on the ground, and dolly towing,
towing your vehicle with two wheels on the ground and
two wheels up on a device known as a dolly.
With the proper preparation and equipment, many
vehicles can be towed in these ways. See “Dinghy
Towing” and “Dolly Towing,” following.
4-27

Here are some important things to consider before you
do recreational vehicle towing:
What is the towing capacity of the towing vehicle?
Be sure to read the tow vehicle manufacturer’s
recommendations.
How far will the vehicle be towed? Some vehicles
have restrictions on how far and how long they
can tow.
Do you have the proper towing equipment? See
your dealer/retailer or trailering professional for
additional advice and equipment recommendations.
Is the vehicle ready to be towed? Just as you would
prepare your vehicle for a long trip, you will want to
make sure the vehicle is prepared to be towed.
SeeBefore Leaving on a Long Trip on page 4-15.
Dinghy Towing
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.
The vehicle was not designed to be towed with all
four wheels on the ground. If the vehicle must be
towed, use a dolly. See “Dolly Towing” following for
more information.
Dolly Towing
The vehicle can be towed using a dolly. To tow your
vehicle using a dolly, follow these steps:
1. Put the front wheels on the dolly.
2. Put the vehicle in PARK (P).
3. Set the parking brake and then remove the key.
4. Clamp the steering wheel in a straight-ahead
position.
5. Release the parking brake.
4-28

Towing a Trailer
{CAUTION:
If you do not 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. You may also damage
your vehicle; the resulting repairs would
not be covered by your warranty. Pull a trailer
only if you have followed all the steps in this
section. Ask your dealer/retailer for advice
and information about towing a trailer with
your vehicle.The vehicle can tow a trailer if it is equipped with the
proper trailer towing equipment. To identify the trailering
capacity of the vehicle, read the information in “Weight of
the Trailer” that appears later in this section. Trailering is
different than just driving the 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 is 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 pulling a trailer.
Load-pulling components such as the engine,
transmission, wheel assemblies, and tires are forced
to work harder against the drag of the added weight.
The engine is required to operate at relatively higher
speeds and under greater loads, generating extra heat.
The trailer also adds considerably to wind resistance,
increasing the pulling requirements.
4-29

If You Do Decide To Pull A Trailer
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 will be driving. A good source
for this information can be state or provincial police.
Consider using a sway control. Ask a hitch
dealer/retailer about sway controls.
Do not tow a trailer at all during the rst 1,000 miles
(1 600 km) the new vehicle is driven. The engine,
axle, or other parts could be damaged.
Then, during the rst 500 miles (800 km) that the
vehicle tows a trailer, do not drive over 50 mph
(80 km/h) and do not make starts at full throttle.
This helps the engine and other parts of the vehicle
wear in at the heavier loads.
Obey speed limit restrictions when towing a trailer.
Do not drive faster than the maximum posted
speed for trailers, or no more than 55 mph
(90 km/h), to save wear on the vehicle’s parts.
Three important considerations have to do with weight:
The weight of the trailer
The weight of the trailer tongue
The total weight on your vehicle’s tires
Weight of the Trailer
How heavy can a trailer safely be?
It should never weigh more than 1,000 lbs (454 kg).
But even that can be too heavy.
It depends on how you plan to use your rig.
For example, speed, altitude, road grades, outside
temperature, and how much the vehicle is used to
pull a trailer are all important. It can also depend
on any special equipment that is on the vehicle,
and the amount of tongue weight the vehicle can
carry. See “Weight of the Trailer Tongue” later in
this section for more information.
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.
Ask your dealer/retailer for our trailering information
or advice, or write us at our Customer Assistance
Offices. SeeCustomer Assistance Offices on page 7-5
for more information.
4-30

Weight of the Trailer Tongue
The tongue load (A) of any trailer is an important weight
to measure because it affects the total or gross weight
of the vehicle. The Gross Vehicle Weight (GVW)
includes the curb weight of the vehicle, any cargo
in it, and the people who will be riding in the vehicle.
If there are a lot of options, equipment, passengers
and cargo in the vehicle, it will reduce the tongue
weight the vehicle can carry, which will also reduce
the trailer weight the vehicle can tow. And if towing
a trailer, the tongue load must be added to the GVW
because the vehicle will be carrying that weight, too.
SeeLoading Your Vehicle on page 4-22for more
information about your vehicle’s maximum load
capacity.When using a weight-carrying hitch or a
weight-distributing hitch, the trailer tongue (A)
should weigh 10 to 15 percent of the total loaded
trailer weight (B).
After the trailer is loaded, weigh the trailer and then
the tongue, separately, to see if the weights are
proper. The correct weight could be achieved simply
by moving some items around in the trailer.
4-31

Trailer Brakes
Does your trailer have its own brakes? Be sure to read
and follow the instructions for the trailer brakes so
you’ll be able to install, adjust and maintain them
properly.
If your vehicle has anti-lock brakes, do not try to
tap into your vehicle’s brake system. If you do,
both brake systems won’t work well, or at all.
Even if your vehicle doesn’t have anti-lock brakes,
don’t tap into your vehicle’s brake system if the
trailer’s brake system will use more than
0.02 cubic inch (0.3 cc) of uid from your vehicle’s
master cylinder. If it does, both braking systems
won’t work well. You could even lose your brakes.
Will the trailer brake parts take 3,000 psi
(20 650 kPa) of pressure? If not, the trailer brake
system must not be used with your vehicle.
If everything checks out this far, then make the
brake uid tap at the upper rear master cylinder
port. But don’t use copper tubing for this. If you do,
it will bend and 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, get to know the 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 is now a good deal longer and not
nearly as responsive as the vehicle is by itself.
Before starting, check the trailer hitch and platform
(and attachments), safety chains, electrical connector,
lamps, tires, and mirror adjustment. If the trailer has
electric brakes, start the vehicle and trailer moving
and then apply the trailer brake controller by hand to
be sure the brakes are working. This lets you check
the electrical connection at the same time.
During your trip, check occasionally to be sure that
the load is secure, and that the lamps and any
trailer brakes are still working.
