Your Traction Control System will help you to maintain
control of the vehicle when you accelerate on a
slippery road. If you are driving in deep snow, turn your
traction system to the TC2 mode. It will improve your
ability to accelerate. SeeIf You Are Stuck: In Sand,
Mud, Ice or Snow on page 4-52. Even though your
vehicle has a traction system, you will want to slow down
and adjust your driving to the road conditions. See
Traction Control System (TCS) on page 4-9.
Your anti-lock brakes improve your vehicle’s stability
when you make a hard stop on a slippery road.
Even though you have an anti-lock braking system, you
will want to begin stopping sooner than you would on
dry pavement. SeeAnti-Lock Brake System (ABS)
on page 4-7.
Allow greater following distance on any
slippery road.
Watch for slippery spots. The road might be ne
until you hit a spot that is covered with ice. On
an otherwise clear road, ice patches may appear in
shaded areas where the sun cannot reach:
around clumps of trees, behind buildings, or under
bridges. Sometimes the surface of a curve or
an overpass may remain icy when the surrounding
roads are clear. If you see a patch of ice ahead
of you, brake before you are on it. Try not to brake
while you’re actually on the ice, and avoid sudden
steering maneuvers.
If You Are Caught in a Blizzard
If you are stopped by heavy snow, you could be in a
serious situation. You should probably stay with
your vehicle unless you know for sure that you are near
help and you can hike through the snow. Here are
some things to do to summon help and keep yourself
and your passengers safe:
Turn on your hazard ashers.
Tie a red cloth to your vehicle to alert police that
you have been stopped by the snow.
4-50

Put on extra clothing or wrap a blanket around you.
If you have no blankets or extra clothing, make
body insulators from newspapers, burlap bags, rags,
oor mats — anything you can wrap around
yourself or tuck under your clothing to keep warm.
You can run the engine to keep warm, but be careful.
{CAUTION:
Snow can trap exhaust gases under your
vehicle. This can cause deadly CO (carbon
monoxide) gas to get inside. CO could
overcome you and kill you. You cannot see it
or smell it, so you might not know it is in your
vehicle. Clear away snow from around the
base of your vehicle, especially any that is
blocking your exhaust pipe. And check around
again from time to time to be sure snow does
not collect there.
Open a window just a little on the side of the
vehicle that is away from the wind. This will
help keep CO out.
Run your engine only as long as you must. This saves
fuel. When you run the engine, make it go a little
faster than just idle. That is, push the accelerator
slightly. This uses less fuel for the heat that you get and
it keeps the battery charged. You will need a
well-charged battery to restart the vehicle, and possibly
for signaling later on with your headlamps. Let the
heater run for a while.

To use the front mounted receiver with the receiver
extension, do the following:
1. Locate the receiver extension (A) in the rear of the
vehicle where it is attached to the spare tire
mounting plate.
2. Loosen the wing nuts (B) holding the extension to
the spare tire plate and remove it.
3. The extension attaches to the front receiver exactly
as the power winch platform does. See “Power
Winch Platform” following in this section.
4. Attach the accessory you will be using to the
receiver extension.Power Winch Platform
You can use the power winch platform (if equipped) with
an aftermarket winch. Connect the winch to the
platform and wiring to the vehicle following the winch
manufacturer’s guidelines.
Notice:Do not use the winch platform to winch at
a tension of more than 9,000 lbs. (4 082 kg). This
would damage your vehicle’s frame. This damage
would not be covered by your vehicle’s warranty.
If you are using a winch to pull out another vehicle,
follow the winch manufacturer’s guidelines and observe
the following to prevent damage to your vehicle:
If possible, have your vehicle anchored from
the opposite side of the winch to a solid,
immovable object.
If winching from the front, use both of the rear
recovery loops. If winching from the rear, use both
of the front recovery loops.
Put your transmission in NEUTRAL (N).
Use your regular brakes to hold your vehicle in
place and block the wheels to keep the vehicle
from moving.
4-57

Notice:Using a power winch with the transmission
in gear to pull out another vehicle may damage
the transmission. When operating a power winch,
always leave the transmission in NEUTRAL (N).
Notice:Driving your vehicle through an automatic
car wash with the winch installed, can cause
damage to your vehicle and the car wash. Always
remove the winch from your vehicle before using an
automatic car wash. SeeWashing Your Vehicle
on page 5-96for more information.
If you are using a winch to pull out your own vehicle,
follow the winch manufacturer’s guidelines for self
recovery and observe the following to prevent damage
to your vehicle:
Do not self recover your vehicle by wrapping the
winch cable around an object (such as a pulley
block or tree) and attaching it back to your vehicle’s
recovery loops.
Always attach the winch cable directly to a solid
anchor directly in front of your vehicle to achieve
a straight line pull.
Loading Your Vehicle
It is very important to know how much weight your
vehicle can carry. This weight is called the vehicle
capacity weight and includes the weight of all occupants,
cargo and all nonfactory-installed options. Two labels
on your vehicle show how much weight it may properly
carry, the Tire and Loading Information label and the
Certication/Tire label.
{CAUTION:
Do not load your vehicle any heavier than the
GVWR, or either the maximum front or rear
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.
4-58

Tire and Loading Information Label
The Tire and Loading Information label is attached to
the center pillar (B-pillar). With the driver’s door
open, you will nd the label attached below the door
lock post (striker). The tire and loading information label
shows the number of occupant seating positions (A),
and the maximum vehicle capacity weight (B) in
kilograms and pounds.The Tire and Loading Information label also shows the
size of the original equipment tires (C) and the
recommended cold tire ination pressures (D). For more
information on tires and ination seeTires on page 5-54
andInation - Tire Pressure on page 5-60.
There is also important loading information on the
vehicle Certication/Tire label. It tells you the Gross
Vehicle Weight Rating (GVWR) and the Gross
Axle Weight Rating (GAWR) for the front and rear axle.
See “Certication/Tire Label” later in this section.
Steps for Determining Correct Load Limit
1. Locate the statement “The combined weight of
occupants and cargo should never exceed
XXX kg or XXX pounds” on your vehicle’s placard.
2. Determine the combined weight of the driver and
passengers that will be riding in your vehicle.
3. Subtract the combined weight of the driver and
passengers from XXX kilograms or XXX pounds. United States version shown, Canada similar

6. Release the parking brake only after the vehicle
being towed is rmly attached to the towing
vehicle. You can use your vehicle’s front mounted
receiver with the proper accessories to tow it.
See “Front Mounted Receiver” underIf You Are
Stuck: In Sand, Mud, Ice or Snow on page 4-52.
7. Turn the engine off and leave the steering
column unlocked.
{CAUTION:
Shifting an all-wheel-drive vehicle’s transfer
case into NEUTRAL can cause your vehicle to
roll even if the transmission is in Park (P). You
or others could be injured. Make sure the
parking brake is rmly set before you shift the
transfer case to NEUTRAL.
Dolly Towing
Your vehicle can not be dolly towed. If you must tow
your vehicle behind another, use the dinghy towing
procedure listed previously.
Notice:Dolly towing your vehicle will
damage drivetrain components. Do not dolly
tow your vehicle.
Selectable Extended Rear
Ride Height
If your vehicle has this feature it comes as part of the
electronically controlled air suspension system.
The selectable rear ride height allows you to raise the
rear of the vehicle about 2 inches (5 cm) over the normal
ride height. This can be helpful when driving off-road
where you may need more ground clearance to clear
an obstacle.
The button that controls
this feature is located
on the instrument panel
to the right of the
steering wheel.
