Rocking Your Vehicle to
Get It Out
Turn the steering wheel left and
right to clear the area around
the front wheels. The traction control
system activates when the system
senses that the wheels are spinning.
Turn off any traction or stability
system. With the wheels straight
ahead, shift back and forth between
R (Reverse) and a forward gear,
or with a manual transmission,
between 1 (First) or 2 (Second) and
R (Reverse), 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 shifting, and
press lightly on the accelerator
pedal when the transmission is in
gear. Slowly spinning the wheels in
the forward and reverse directions
causes a rocking motion that
could free the vehicle. If that does
not get the vehicle out after a
few tries, it might need to be towed
out. The recovery loops can beused. If the vehicle does need to be
towed out, seeTowing Your
Vehicle on page 4-40.
Recovery Loops
{CAUTION
These loops, when used, are
under a lot of force. Keep people
away from the vicinity of the loops
and any chains or cables during
use. Always pull the vehicle
straight out. Never pull on the
loops at a sideways angle. The
loops could break off and you or
others could be injured from the
chain or cable snapping back.
Notice:Never use the recovery
loops to tow the vehicle. Your
vehicle could be damaged and it
would not be covered by
warranty.The vehicle has two recovery loops
at the front of the vehicle and
one at the rear of the vehicle.
Use them if the vehicle is stuck
off-road and needs to be pulled to
some place where the driver
can continue driving.
4-34 Driving Your Vehicle

Use the following procedure to tow
the vehicle:
1. Put the transmission in P (Park)
for an automatic transmission or
in 1 (First) for a manual
transmission.
2. Turn the engine off, but leave the
ignition in ACC/ACCESSORY.
3. Firmly set the parking brake.
4. Securely attach the vehicle being
towed to the tow vehicle.
{CAUTION
Shifting a full-time
four-wheel-drive vehicle’s
transfer case into N (Neutral)
can cause the vehicle to roll
even if the automatic transmission
is in P (Park) or the manual
transmission is in any gear. You
or others could be injured. Make
sure the parking brake is rmly
set before the transfer case is
shifted to N (Neutral).5. Shift the transfer case to
N (Neutral). SeeFull-Time
Four-Wheel Drive on page 2-24
for the proper procedure to
select the N (Neutral) position for
the vehicle.
6. Release the parking brake only
after the vehicle being towed is
rmly attached to the tow vehicle.
7. Make sure the ignition is in
ACC/ACCESSORY.
When towing the vehicle for
extended periods of time, start the
vehicle as often as possible to
prevent battery drain. This should
only be done when the tow
vehicle is parked.
After towing, see “Shifting Out of
NEUTRAL” underFull-Time
Four-Wheel Drive on page 2-24.
Dolly Towing
Notice:Dolly towing the vehicle
will damage drivetrain
components. Do not dolly tow the
vehicle.
The vehicle cannot be dolly towed.
If the vehicle must be towed
behind another vehicle, use the
dinghy towing procedure explained
previously.
Driving Your Vehicle 4-41

Do not tow a trailer at all during
the rst 500 miles (800 km) the
new vehicle is driven. The
engine, axle or other parts could
be damaged.
Then, during the rst 500 miles
(800 km) that a trailer is towed,
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.
Vehicles with an automatic
transmissions can tow in
D (Drive). Shift the transmission
to a lower gear if the
transmission shifts too often
under heavy loads and/or hilly
conditions. For vehicles with
a manual transmission, it is better
not to use the highest gear.
This vehicle has a Hill Start
Assist feature, which may
be useful when the vehicle is
stopped on a grade. SeeBraking
on page 4-3for more information.
Three important considerations have
to do with weight:
The weight of the trailer
The weight of the trailer tongue
The weight on the vehicle’s tires
Weight of the Trailer
How heavy can a trailer safely be?
It depends on how the rig is
used. For example, speed, altitude,
road grades, outside temperature
and how much the vehicle is used to
pull a trailer are all important. It
can depend on any special
equipment 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.
Driving Your Vehicle 4-43

Maximum trailer weight is calculated
assuming only the driver is in the
tow vehicle and it has all the
required trailering equipment. Theweight of additional optional
equipment, passengers and cargo in
the tow vehicle must be subtracted
from the maximum trailer weight.Use the following chart to determine
how much the vehicle can weigh,
based upon the vehicle model
and options.

Making Turns
Notice:Making very sharp turns
while trailering could cause
the trailer to come in contact with
the vehicle. The vehicle could
be damaged. Avoid making very
sharp turns while trailering.
When turning with a trailer, make
wider turns than normal. Do this
so the trailer won’t strike soft
shoulders, curbs, road signs, trees
or other objects. Avoid jerky or
sudden maneuvers. Signal well in
advance.
Turn Signals When Towing a
Trailer
The arrows on the instrument panel
ash whenever signaling a turn
or lane change. Properly hooked up,
the trailer lamps also ash, telling
other drivers the vehicle is turning,
changing lanes or stopping.When towing a trailer, the arrows
on the instrument panel ash
for turns even if the bulbs on the
trailer are burned out. For this
reason you may think other drivers
are seeing the signal when they
are not. It is important to check
occasionally to be sure the trailer
bulbs are still working.
Driving On Grades
Reduce speed and shift to a lower
gearbeforestarting down a long
or steep downgrade. If the
transmission is not shifted down, the
brakes might have to be used so
much that they would get hot and no
longer work well.
Vehicles with an automatic
transmission can tow in D (Drive).
Shift the transmission to a lower
gear if the transmission shifts
too often under heavy loads and/or
hilly conditions. For vehicles with
a manual transmission, it is
better not to use the highest gear.When towing at high altitude on
steep uphill grades, consider
the following: Engine coolant will
boil at a lower temperature than at
normal altitudes. If the engine is
turned off immediately after towing
at high altitude on steep uphill
grades, the vehicle may show signs
similar to engine overheating. To
avoid this, let the engine run
while parked, preferably on level
ground, with the automatic
transmission in P (Park) for a
few minutes before turning the
engine off. For vehicles with manual
transmissions, let the engine run
while parked, preferably on
level ground, with the transmission
out of gear and the parking
brake applied, for a few minutes
before turning the engine off. If the
overheat warning comes on,
seeEngine Overheating on
page 5-27.
