•AUTO: This four-wheel drive operation is a continu-
ous operation, is fully automatic and can be used on
and off road. This mode balances traction to ensure
maneuverability and acceleration improvement com-
pared to a vehicle with two wheel drive. This modealso reduces fuel consumption, since it allows the
disconnect of the drive shaft where conditions permit.
•SNOW: This mode allows you to have greater stability
under conditions of bad weather. For use on and off
road on surfaces with poor traction, such as roads
covered with snow. When in SNOW mode (depending
on certain operating conditions), the transmission may
use second gear (rather than first gear) during
launches, to minimize wheel slippage.
•SAND: For off-road driving or use on surfaces with
poor traction, such as sandy bottoms. The transmission
is set to provide maximum traction.
•MUD: For off-road driving or use on surfaces with
poor traction, such as roads covered by mud or wet
grass.

NOTE:
•FCW monitors the information from the forward look-
ing sensors as well as the Electronic Brake Controller
(EBC), to calculate the probability of a forward colli-
sion. When the system determines that a forward
collision is probable, the driver will be provided with
audible and visual warnings and may provide a brake
jerk warning.
•If the driver does not take action based upon these
progressive warnings, then the system will provide a
limited level of active braking to help slow the vehicle
and mitigate the potential forward collision. If the
driver reacts to the warnings by braking and the
system determines that the driver intends to avoid the
collision by braking but has not applied sufficient
brake force, the system will compensate and provide
additional brake force as required.Vehicles With A Manual Transmission: After the end of
the intervention of automatic braking, the engine could
stall, unless the driver can depress the clutch pedal.
Vehicles With Automatic Transmission: After the end of
the intervention of automatic braking, the transmission
may remain in last gear stored: therefore the car could
lurch forward, once the brakes release a few seconds
later. If the Forward Collision Warning with Mitigation
event stops the vehicle completely, the system will hold
the vehicle at standstill for two seconds and then release
the brakes.
If a Forward Collision Warning with Mitigation event
begins at a speed below 20 mph (32 km/h), the system
may provide the maximum braking possible to mitigate
the potential forward collision. If the Forward Collision
Warning with Mitigation event stops the vehicle com-
pletely, the system will hold the vehicle at standstill for
two seconds and then release the brakes.

Flowing Water
If the water is swift flowing and rising (as in storm run-off)
avoid crossing until the water level recedes and/or the
flow rate is reduced. If you must cross flowing-water, avoid
depths in excess of 9 inches (22 cm). The flowing water can
erode the streambed causing your vehicle to sink into
deeper water. Determine exit point(s) that are downstream
of your entry point to allow for drifting.
Standing Water
Avoid driving in standing water deeper than 19 inches
(48 cm), and reduce speed appropriately to minimize
wave effects. Maximum speed in 19 inches (48 cm) of
water is less than 5 mph (8 km/h).
Maintenance
After driving through deep water, inspect your vehicle
fluids and lubricants (engine, transmission, Power Trans-
fer Unit and Rear Drive Module) to assure they have notbeen contaminated. Contaminated fluids and lubricants
(milky, foamy in appearance) should be flushed/changed
as soon as possible to prevent component damage.
Driving In Snow, Mud And Sand
In heavy snow, when pulling a load, or for additional
control at slower speeds, shift the transmission to a low
gear and shift the 4WD system to the appropriate terrain
mode, using 4WD LOW if necessary. Refer to “Four-
Wheel Drive Operation” in “Starting And Operating” for
further information. Do not shift to a lower gear than
necessary to maintain headway. Over-revving the engine
can spin the wheels and traction will be lost.
Avoid abrupt downshifts on icy or slippery roads be-
cause engine braking may cause skidding and loss of
control.

Hill Climbing
NOTE:Before attempting to climb a hill, determine the
conditions at the crest and/or on the other side.
Before climbing a steep hill,shift the transmission to a
lower gear and shift the 4WD System to 4WD LOW. Use
first gear and 4WD LOW for very steep hills.
If you stall or begin to lose headwaywhile climbing a
steep hill, allow your vehicle to come to a stop and
immediately apply the brakes. Restart the engine and
shift to REVERSE. Back slowly down the hill allowing the
compression braking of the engine to help regulate your
speed. If the brakes are required to control vehicle speed,
apply them lightly and avoid locking or skidding the
tires.
WARNING!
If the engine stalls or you lose headway or cannot
make it to the top of a steep hill or grade, never
attempt to turn around. To do so may result in
tipping and rolling the vehicle. Always back straight
down a hill in REVERSE gear carefully. Never back
down a hill in NEUTRAL using only the brake.
NOTE:Remember, never drive diagonally across a hill -
drive straight up or down.
If the wheels start to slip as you approach the crest of a
hill, ease off the accelerator and maintain headway by
turning the front wheels slowly left and right. This may
provide a fresh “bite” into the surface and will usually
provide traction to complete the climb.

Traction Downhill
Shift the transmission into a low gear and the 4WD
System to 4WD LOW range or Select Hill Descent
Control if equipped (refer toElectronic Brake Control
Systemin this section for further information). Let the
vehicle go slowly down the hill with all four wheels
turning against engine compression drag. This will per-
mit you to control the vehicle speed and direction.
When descending mountains or hills, repeated braking
can cause brake fade with loss of braking control. Avoid
repeated heavy braking by downshifting the transmis-
sion whenever possible.
After Driving Off-Road
Off-road operation puts more stress on your vehicle than
does most on-road driving. After going off-road, it is
always a good idea to check for damage. That way you
can get any problems taken care of right away and have
your vehicle ready when you need it.•Completely inspect the underbody of your vehicle.
Check tires, body structure, steering, suspension, and
exhaust system for damage.
•Inspect the radiator for mud and debris and clean as
required.
•Check threaded fasteners for looseness, particularly on
the chassis, drivetrain components, steering, and sus-
pension. Retighten them, if required, and torque to the
values specified in the Service Manual.
•Check for accumulations of plants or brush. These
things could be a fire hazard. They might hide damage
to fuel lines, brake hoses, axle pinion seals, and
propeller shafts.
•After extended operation in mud, sand, water, or
similar dirty conditions, have the radiator, fan, brake
rotors, wheels, brake linings, and axle yokes inspected
and cleaned as soon as possible.

NOTE:Remember that everything put into or on the
trailer adds to the load on your vehicle. Also, additional
factory-installed options or dealer-installed options must
be considered as part of the total load on your vehicle.
Refer to the “Tire And Loading Information” placard for
the maximum combined weight of occupants and cargo
for your vehicle.
Towing Requirements
To promote proper break-in of your new vehicle drive-
train components, the following guidelines are recom-
mended:
WARNING!
Improper towing can lead to a collision. Follow these
guidelines to make your trailer towing as safe as
possible:
(Continued)
WARNING!(Continued)
•Make certain that the load is secured in the trailer
and that it will not shift during travel. When
trailering cargo that is not fully secured, dynamic
load shifts can occur that may be difficult for the
driver to control. You could lose control of your
vehicle and have a collision.
•When hauling cargo, or towing a trailer, do not
overload your vehicle or trailer. Overloading can
cause a loss of control, poor performance, or dam-
age to brakes, axle, engine, transmission, steering,
suspension, chassis structure, or tires.
•Safety chains must always be used between your
vehicle and trailer. Always connect the chains to
the frame or hook retainers of the vehicle hitch.
Cross the chains under the trailer tongue and allow
enough slack for turning corners.

WARNING!(Continued)
•Vehicles with trailers should not be parked on a
grade. When parking, apply the parking brake on
the tow vehicle. Put the tow vehicle transmission in
PARK. Always, block orchockthe trailer wheels.
•GCWR must not be exceeded.
•Total weight must be distributed between the tow
vehicle and the trailer such that the following four
ratings are not exceeded:
1. GVWR
2. GTW
3. GAWR
4. Tongue weight rating for the trailer hitch uti-
lized.
CAUTION!
•Do not tow a trailer at all during the first 500 miles
(805 km) the new vehicle is driven. The engine, axle
or other parts could be damaged.
•Then, during the first 500 miles (805 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.
Towing Requirements — Tires
•Do not attempt to tow a trailer while using a compact
spare tire.
•Proper tire inflation pressures are essential to the safe
and satisfactory operation of your vehicle. Refer to
“Tires – General Information” in “Starting And Oper-
ating” for proper tire inflation procedures.

Towing Tips
Before setting out on a trip, practice turning, stopping,
and backing the trailer in an area located away from
heavy traffic.
Automatic Transmission — If Equipped
The DRIVE range can be selected when towing. The
transmission controls include a drive strategy to avoid
frequent shifting when towing. However, if frequent
shifting does occur while in DRIVE, you can use the
AutoStick shift control to manually select a lower gear.
NOTE:Using a lower gear while operating the vehicle
under heavy loading conditions will improve perfor-
mance and extend transmission life by reducing exces-
sive shifting and heat build up. This action will also
provide better engine braking.
AutoStick
•When using the AutoStick shift control, select the
highest gear that allows for adequate performance and
avoids frequent downshifts. For example, choose “5” if
the desired speed can be maintained. Choose “4” or
“3” if needed to maintain the desired speed.
•To prevent excess heat generation, avoid continuous
driving at high RPM. Reduce vehicle speed as neces-
sary to avoid extended driving at high RPM. Return to
a higher gear or vehicle speed when grade and road
conditions allow.
