Four-wheel drive (when you select a 4WD
mode) uses all four wheels to power the
vehicle. This increases traction, enabling you
to drive over terrain and road conditions that
a conventional two-wheel drive vehicle
cannot.
Basic Operating Principles
•
Do not use 4X4 mode on dry, hard
surfaced roads. Doing so will produce
excessive noise, increase tire wear and
may damage drive components. 4X4
mode is only intended for consistently
slippery or loose surfaces.
• Drive slower in strong crosswinds which
can affect the normal steering
characteristics of your vehicle.
• When driving your vehicle on surfaces
made slippery by loose sand, water,
gravel, snow or ice proceed with care. If Your Vehicle leaves the Road
If your vehicle leaves the road, reduce your
vehicle speed and avoid severe braking.
When your vehicle speed has been reduced
ease your vehicle back onto the road. Do
not turn the steering wheel sharply while
returning your vehicle to the road.
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 35 mph
(56 km/h). The tires may fail and injure
a passenger or bystander. Note:
Do not rock your vehicle if the engine
is not at normal operating temperature,
damage to the transmission may occur.
Note: Do not rock your vehicle for more than
a minute, damage to the transmission and
tires may occur or the engine may overheat.
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.
Emergency Maneuvers
In an unavoidable emergency situation
where a sudden sharp turn must be made,
remember to avoid over-driving your vehicle
(i.e. turn the steering wheel only as rapidly
and as far as required to avoid the
emergency). Excessive steering can result
177
Navigator (TB5) Canada/United States of America, enUSA, First Printing Four-Wheel Drive (If Equipped)

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 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 (i.e. from concrete to gravel) there
will be a change in the way your vehicle
responds to a maneuver (i.e. 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.
Mud and Water
Note:
Driving through deep water may
damage the vehicle.
If you must drive through high water, drive
slowly. Traction or brake capability may be
limited.
When driving through water, determine the
depth and avoid water higher than the
bottom of the hubs. If the ignition system
gets wet, your vehicle may stall.
Once through water, always try the brakes.
Wet brakes do not stop your vehicle as
effectively as dry brakes. Drying can be
improved by applying light pressure to the
brake pedal while moving slowly. Be cautious of sudden changes in vehicle
speed or direction when you are driving in
mud. Even 4WD vehicles can lose traction in
slick mud. As when you are driving over
sand, apply the accelerator slowly and avoid
spinning your wheels. If the vehicle does
slide, steer in the direction of the slide until
you regain control of the vehicle.
If the transmission, transfer case or front axle
are submerged in water, their fluids should
be checked and changed, if necessary.
If the front or rear axle is submerged in water,
the axle lubricant should be replaced.
After driving through mud, clean off residue
stuck to rotating driveshafts and tires. Excess
mud stuck on tires and rotating driveshafts
causes an imbalance that could damage
drive components.

.
Driving on Hilly or Sloping Terrain
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.
Although natural obstacles may make it
necessary to travel diagonally up or down a
hill or steep incline, you should always try to
drive straight up or straight down. When climbing a steep slope or hill, start in
a lower gear rather than downshifting to a
lower gear from a higher gear once the
ascent has started. This reduces strain on
the engine and the possibility of stalling.
If your vehicle stalls, do not try to turn around
because this could cause vehicle roll over.
It is better to reverse back to a safe location.
Apply just enough power to the wheels to
climb the hill. Too much power will cause the
tires to slip, spin or lose traction, resulting in
loss of vehicle control. Descend a hill in the same gear you would
use to climb up the hill to avoid excessive
brake application and brake overheating. Do
not descend in neutral. Disengage overdrive
or move the transmission selector lever to a
lower gear. When descending a steep hill,
avoid sudden hard braking as you could lose
control. The front wheels have to be turning
in order to steer your vehicle.
If your vehicle has anti-lock brakes, apply the
brakes steadily. Do not pump the brakes.
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. 179

LIMITED SLIP DIFFERENTIAL
This axle provides added traction on slippery
surfaces, particularly when one wheel is on
a poor traction surface. Under normal
conditions, the limited-slip axle functions like
a standard rear axle. The axle may exhibit a
slight noise or vibration during tight turns
with low vehicle speed. This is normal
behavior and indicates the axle is working.

GENERAL INFORMATION
Note:
Occasional brake noise is normal. If a
metal-to-metal, continuous grinding or
continuous squeal sound is present, the
brake linings may be worn-out. Have the
system checked by an authorized dealer. If
your vehicle has continuous vibration or
shudder in the steering wheel while braking,
have it checked by an authorized dealer.
Note: Brake dust may accumulate on the
wheels, even under normal driving
conditions. Some dust is inevitable as the
brakes wear and does not contribute to
brake noise. See Cleaning the Alloy Wheels
(page 292). See
Warning Lamps and
Indicators (page 98).
Wet brakes result in reduced braking
efficiency. Gently press the brake pedal a
few times when driving from a car wash or
standing water to dry the brakes. Brake Over Accelerator
In the event the accelerator pedal becomes
stuck or entrapped, apply steady and firm
pressure to the brake pedal to slow the
vehicle and reduce engine power. If you
experience this condition, apply the brakes
and bring your vehicle to a safe stop. Move
the transmission to park (P), switch the
engine off and apply the parking brake.
Inspect the accelerator pedal for any
interference. If none are found and the
condition persists, have your vehicle towed
to the nearest authorized dealer.
Brake Assist
Brake assist detects when you brake rapidly
by measuring the rate at which you press the
brake pedal. It provides maximum braking
efficiency as long as you press the pedal,
and can reduce stopping distances in critical
situations.
Anti-lock Brake System
This system helps you maintain steering
control during emergency stops by keeping
the brakes from locking. This lamp momentarily illuminates
when you turn the ignition on. If
the light does not illuminate during
start up, remains on or flashes, the system
may be disabled. Have the system checked
by an authorized dealer. If the anti-lock brake
system is disabled, normal braking is still
effective. If the brake warning lamp remains
illuminated after you release the
parking brake, have the system
checked by an authorized dealer.
HINTS ON DRIVING WITH ANTI-
LOCK BRAKES
Note: When the system is operating, the
brake pedal may pulse and may travel
further. Maintain pressure on the brake
pedal. You may also hear a noise from the
system. This is normal.
182
Navigator (TB5) Canada/United States of America, enUSA, First Printing BrakesE144522 E144522

When the system is active, your vehicle will
remain stationary on the slope for two to
three seconds after you release the brake
pedal. This allows you time to move your foot
from the brake to the accelerator pedal. The
brakes release automatically when the
engine has sufficient torque to prevent your
vehicle from rolling down the grade. This is
an advantage when pulling away on a slope,
for example from a car park ramp, traffic
lights or when reversing uphill into a parking
space.
The system will activate automatically on any
slope that will cause significant vehicle
rollback. For vehicles with a manual
transmission, you can switch this feature off
using the information display. See
Information Displays (page 102). The system
will remain on or off depending on how it
was last set.
Note: There is no warning lamp to indicate
the system is either on or off.
Note: If your vehicle is equipped with Auto
Hold, Hill Start Assist will not be available
while Auto Hold is active. Using Hill Start Assist
1. Bring your vehicle to a complete
standstill. Keep the brake pedal pressed
and select an uphill gear (for example,
first (1) when facing uphill or reverse (R)
when facing downhill).
2. If the sensors detect that your vehicle is on a slope, the system will activate
automatically.
3. When you remove your foot from the brake pedal, your vehicle will remain on
the slope without rolling away for about
two or three seconds. This hold time will
automatically be extended if you are in
the process of driving off.
4. Drive off in the normal manner. The brakes will release automatically.
Switching the System On and Off
You can switch this feature on or off if your
vehicle is equipped with a manual
transmission and an information display. See
General Information (page 102). The system
remembers the last setting when you start
your vehicle. If your vehicle is not equipped with a manual
transmission and an information display, you
cannot turn the system on or off. When you
switch the ignition on, the system
automatically turns on.

PRINCIPLE OF OPERATION
The traction control system helps avoid drive
wheel spin and loss of traction.
If your vehicle begins to slide, the system
applies the brakes to individual wheels and,
when needed, reduces engine power at the
same time. If the wheels spin when
accelerating on slippery or loose surfaces,
the system reduces engine power in order
to increase traction.
USING TRACTION CONTROL WARNING
The stability and traction control light
illuminates steadily if the system
detects a failure. Make sure you did not
manually disable the traction control system
using the switch. If the stability control and
traction control light is still illuminating
steadily, have the system serviced by an
authorized dealer immediately. Operating
your vehicle with traction control disabled
could lead to an increased risk of loss of
vehicle control, vehicle rollover, personal
injury and death. The system automatically turns on each time
you switch the ignition on.
If your vehicle is stuck in mud or snow,
switching traction control off may be
beneficial as this allows the wheels to spin.
Note:
When you switch traction control off,
stability control remains fully active. Switching the System Off
The switch for the stability and traction
control system is on the instrument panel.
When you switch the system off, a message
and an illuminated icon appear on the
instrument cluster.
Use the switch again to return the traction
control system to normal operation.
Your vehicle may have MyKey restrictions
regarding this feature. See Principle of
Operation (page 54).
