USING FOUR-WHEEL DRIVE
Note:
Please review important information
regarding the safe operation of this type of
vehicle. See General Information (page 407).
Note: Do not use slippery, deep conditions
or slow climb on dry, hard surfaced roads.
Doing so produces excessive noise,
increases tire wear and could damage drive
components. The four-wheel drive system
in these modes is only intended for
consistently slippery or loose surfaces.
Note: If you select a drive mode that uses
4L when your vehicle is moving above 3 mph
(5 km/h)
, the four-wheel drive system does
not perform a shift. This is normal and should
be no reason for concern.
4X4 Indicator Lights
4X2 Momentarily illuminates when you
start the vehicle or when a drive
mode that uses 2H is selected. 4X4 AUTO Continuously illuminates when a
drive mode that uses 4A is
selected.
4X4 HIGH Continuously illuminates when a
drive mode that uses 4H is
selected.
4X4 LOW (If Equipped) Continuously illuminates when a
drive mode that uses 4L is
selected.
CHECK 4X4 Displays when a 4X4 fault is
present.Note:
When a 4X4 system fault is present,
the system typically remains in whichever
4X4 mode was selected prior to the fault
condition occurring. It does not necessarily
default to 4X2. When this warning is
displayed, have your vehicle serviced as
soon as possible.
4X4 Modes WARNING:
Vehicles with a higher
center of gravity (utility and four-wheel
drive vehicles) handle differently than
vehicles with a lower center of gravity
(passenger cars). Avoid sharp turns,
excessive speed and abrupt steering in
these vehicles. Failure to drive cautiously
increases the risk of losing control of your
vehicle, vehicle rollover, personal injury
and death.
Your vehicle engages 4X4 modes based on
the currently selected drive mode.
See Drive
Mode Control (page 303).
Note: The information display could show
messages during four-wheel drive operation.
See
Information Messages (page 139).

Shifting to or from 4L - 4X4 LOW
1. Bring the vehicle to a rolling speed of
3 mph (5 km/h) or less.
2. Place the gearshift in neutral (N).
3. Rotate the drive mode knob to the desired mode.
The information display shows a message
indicating a 4X4 shift is in progress. The
information display shows the system mode
selected. If any of the previous shift
conditions are not present, the shift does not
occur and the information display shows the
information guiding the driver through the
proper shifting procedures. If the previous
conditions are not satisfied within 30
seconds, the system reverts to the previous
drive mode.
If shift delayed pull forward displays in the
information display, a transfer case gear
tooth blockage is present. To alleviate this
condition, place the transmission in a forward
gear, move the vehicle forward
approximately
5 ft (2 m), and shift the
transmission back to neutral (N) to allow the
transfer case to complete the range shift. Note:
Using 4L mode is not intended to be
used on dry pavement.
Operating Four-Wheel Drive Vehicles
with Spare or Mismatched Tires
On four-wheel drive vehicles, the size of the
spare tire can affect the four-wheel drive
system. If there is a significant difference
between the size of the spare tire and the
remaining tires, you may have limited
four-wheel drive functionality.
When driving with the full-size dissimilar
spare wheel and tire assembly, it is
recommended that you do not:
• Exceed
50 mph (80 km/h) with a
four-wheel drive mode turned on.
• Turn on a four-wheel drive mode unless
the vehicle is stationary.
• Use a four-wheel drive mode on dry
pavement.
Use of a dissimilar spare wheel and tire
assembly may lead to impairment of the
following:
• Comfort and noise.
• Winter weather driving capability. •
Wet driving capability.
• Four-wheel drive capability.
How Your Vehicle Differs from Other
Vehicles WARNING:
Vehicles with a higher
center of gravity (utility and four-wheel
drive vehicles) handle differently than
vehicles with a lower center of gravity
(passenger cars). Avoid sharp turns,
excessive speed and abrupt steering in
these vehicles. Failure to drive cautiously
increases the risk of losing control of your
vehicle, vehicle rollover, personal injury
and death.
Truck and utility vehicles can differ from
some other vehicles. Your vehicle may be
higher to allow it to travel over rough terrain
without getting hung up or damaging
underbody components.
The differences that make your vehicle so
versatile also make it handle differently than
an ordinary passenger car.
235
Navigator (TB9) Canada/United States of America, enUSA, First-Printing Four-Wheel Drive
(If Equipped)

It may be safer to stay on the shoulder of the
road and slow down gradually before
returning to the road. You may lose control
if you do not slow down or if you turn the
steering wheel too sharply or abruptly.
It may be less risky to strike small objects,
such as freeway reflectors, with minor
damage to your vehicle rather than attempt
a sudden return to the road which could
cause your vehicle to slide sideways out of
control or roll over. Remember, your safety
and the safety of others should be your
primary concern.
If Your Vehicle Gets Stuck
WARNING: Do not spin the wheels
at over 34 mph (55 km/h). The tires may
fail and injure a passenger or bystander.
If your vehicle gets stuck in mud or snow it
may be rocked out by shifting between
forward and reverse gears, stopping
between shifts, in a steady pattern. Press
lightly on the accelerator in each gear. Note:
Do not rock your vehicle if the engine
is not at normal operating temperature or
damage to the transmission could occur.
Note: Do not rock your vehicle for more than
a minute or damage to the transmission and
tires may occur or the engine could
overheat.
Emergency Maneuvers
In an unavoidable emergency where a
sudden sharp turn must be made, remember
to avoid over-driving your vehicle, for
example, turn the steering wheel only as
rapidly and as far as required to avoid the
emergency. Excessive steering can result in
loss of vehicle control. Apply smooth
pressure to the accelerator pedal or brake
pedal when changes in vehicle speed are
required. Avoid abrupt steering, acceleration
and braking. This could result in an increased
risk of vehicle roll over, loss of vehicle control
and personal injury. Use all of the available
road surface to bring your vehicle to a safe
direction of travel. In the event of an emergency stop, avoid
skidding the tires and do not attempt any
sharp steering wheel movements.
If your vehicle goes from one type of surface
to another such as from concrete to gravel,
there may be a change in the way your
vehicle responds to a maneuver, for
example, steering, acceleration or braking.
Sand
When driving over sand, try to keep all four
wheels on the most solid area of the trail.
Avoid reducing the tire pressures but shift
to a lower gear and drive steadily through
the terrain. Apply the accelerator slowly and
avoid excessive wheel slip.
Avoid driving at excessive speeds, this
causes vehicle momentum to work against
you and your vehicle could become stuck to
the point that assistance may be required
from another vehicle. Remember, you may
be able to back out the way you came if you
proceed with caution.

(If Equipped)

Note:
Avoid driving crosswise or turning on
steep slopes or hills.
Note: Avoid turning on steep slopes or hills.
A danger lies in losing traction, slipping
sideways and possible vehicle roll over.
Whenever driving on a hill, determine
beforehand the route you will use. Do not
drive over the crest of a hill without seeing
what conditions are on the other side. Do
not drive in reverse over a hill without the
aid of an observer.
Driving on Snow and Ice WARNING: If you are driving in
slippery conditions that require tire chains
or cables, then it is critical that you drive
cautiously. Keep speeds down, allow for
longer stopping distances and avoid
aggressive steering to reduce the chances
of a loss of vehicle control which can lead
to serious injury or death. If the rear end
of your vehicle slides while cornering, steer
in the direction of the slide until you regain
control of your vehicle. Four-wheel drive vehicles have advantages
over two-wheel drive vehicles in snow and
ice but can skid like any other vehicle.
Should you start to slide when driving on
snowy or icy roads, turn the steering wheel
in the direction of the slide until you regain
control.
Avoid sudden applications of power and
quick changes of direction on snow and ice.
Apply the accelerator slowly and steadily
when starting from a full stop.
Avoid sudden braking. Although a four-wheel
drive vehicle may accelerate better than a
two-wheel drive vehicle in snow and ice, it
does not stop any faster as braking occurs
at all four wheels. Do not become
overconfident in any road condition.
Make sure you allow sufficient distance
between you and other vehicles for stopping.
Drive slower than usual and consider using
one of the lower gears. In emergency
stopping situations, apply the brake steadily.
Do not pump the brake pedal. See Hints on
Driving With Anti-Lock Brakes
(page 242).
Note: Excessive tire slippage can cause
transmission damage. Maintenance and Modifications
The suspension and steering systems on
your vehicle have been designed and tested
to provide predictable performance whether
loaded or empty. For this reason, we strongly
recommend that you do not make
modifications such as adding or removing
parts, for example, lift kits or stabilizer bars,
or by using replacement parts not equivalent
to the original factory equipment.
We recommend that you use caution when
your vehicle has either a high load or device
such as a ladder or luggage racks. Any
modifications to your vehicle that raise the
center of gravity could cause your vehicle to
roll over when there is a loss of vehicle
control.
Failure to maintain your vehicle correctly
could void the warranty, increase your repair
cost, reduce vehicle performance and
operational capabilities and adversely affect
you and your passenger's safety. We
recommend you frequently inspect your
vehicle's chassis components when your
vehicle is subject to off-road usage.

LIMITED SLIP DIFFERENTIAL (IF
EQUIPPED)
The Electronic Limited Slip Differential (eLSD)
system directs torque, enabling the vehicle
to drive over terrain and road conditions that
a conventional axle cannot. The system is
active at all times and requires no input from
the driver.
Note: If your vehicle is not at optimal
operating conditions or a system fault is
present, a warning may be displayed in the
instrument cluster. Depending on the
warning, your vehicle may need to be
serviced. You can find more information
regarding the system information messages
in the Information Displays chapter.
See
Information Messages (page 139).
Spare Tire
If your vehicle has an Electronic Limited Slip
Differential, do not use a spare tire of a
different size than the tire provided. If a spare
tire is installed, a message may appear,
indicating the system has disabled
automatically or reduced function to prevent system overheat and damage. It is
recommended to reinstall the repaired or
replaced road tire as soon as possible. When
the road tire is replaced, the system will
resume normal operation on the next key
cycle.
Trailer Towing
The Electronic Limited Slip Differential
enhances vehicle stability during trailer tow
operation. During high demand trailering
events, such as steep slopes, high speeds
or with a spare tire, the system may provide
a warning in the instrument cluster and
reduce function or enter a temporarily
disabled state. To resume normal function,
stop the vehicle in a safe location and allow
the unit to adequately cool. Once the system
has reached normal operating temperatures,
system function will be restored and the
Electronic Limited Slip Differential Restored
message will be displayed.
