Note:
Excessive tire slippage can cause
transmission damage.
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 while 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
will 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 182). 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 (i.e. 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
(i.e. ladder or luggage racks). Any
modifications to your vehicle that raise the
center of gravity may cause your vehicle to
roll over when there is a loss of vehicle
control.
Failure to maintain your vehicle correctly may
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.

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

The anti-lock braking system will not
eliminate the risks when:
•
You drive too closely to the vehicle in
front of you.
• Your vehicle is hydroplaning.
• You take corners too fast.
• The road surface is poor.
PARKING BRAKE WARNING
Always set the parking brake fully and
make sure the transmission is placed
in park (P). Failure to set the parking brake
and engage park could result in vehicle
roll-away, property damage or bodily injury.
Turn the ignition to the lock position and
remove the key whenever you leave your
vehicle. Apply the parking brake whenever your
vehicle is parked. Press the pedal downward
to set the parking brake. The brake warning
lamp in the instrument cluster will illuminate
and remains illuminated until the parking
brake is released.
To release, pull the brake release lever
located at the lower left side of the
instrument panel.
If you are parking your vehicle on a grade or
with a trailer, press and hold the brake pedal
down, then set the parking brake. There may
be a little vehicle movement as the parking
brake sets to hold the vehicle's weight. This
is normal and should be no reason for
concern. If needed, press and hold the
service brake pedal down, then try
reapplying the parking brake. Chock the
wheels if required. If the parking brake
cannot hold the weight of the vehicle, the
parking brake may need to be serviced or
the vehicle may be overloaded.
HILL START ASSIST WARNINGS
The system does not replace the
parking brake. When you leave your
vehicle, always apply the parking brake and
shift the transmission into park (P) (automatic
transmission) or first gear (1) (manual
transmission). You must remain in your vehicle once
you have activated the system.
During all times, you are responsible
for controlling your vehicle, supervising
the system and intervening, if required. If the engine is revved excessively, or
if a malfunction is detected, the system
will be deactivated. The system makes it easier to pull away
when your vehicle is on a slope without the
need to use the parking brake.
183
Navigator (TB5) Canada/United States of America, enUSA, First Printing Brakes

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).

PRINCIPLE OF OPERATION
WARNINGS
Vehicle modifications involving braking
system, aftermarket roof racks,
suspension, steering system, tire
construction and wheel and tire size may
change the handling characteristics of your
vehicle and may adversely affect the
performance of the electronic stability control
system. In addition, installing any stereo
loudspeakers may interfere with and
adversely affect the electronic stability
control system. Install any aftermarket stereo
loudspeaker as far as possible from the front
center console, the tunnel, and the front
seats in order to minimize the risk of
interfering with the electronic stability control
sensors. Reducing the effectiveness of the
electronic stability control system could lead
to an increased risk of loss of vehicle control,
vehicle rollover, personal injury and death. WARNINGS
Remember that even advanced
technology cannot defy the laws of
physics. It’ s always possible to lose control
of a vehicle due to inappropriate driver input
for the conditions. Aggressive driving on any
road condition can cause you to lose control
of your vehicle increasing the risk of personal
injury or property damage. Activation of the
electronic stability control system is an
indication that at least some of the tires have
exceeded their ability to grip the road; this
could reduce the operator’ s ability to control
the vehicle potentially resulting in a loss of
vehicle control, vehicle rollover, personal
injury and death. If your electronic stability
control system activates, SLOW DOWN. The system automatically turns on each time
you switch the ignition on.
If a fault occurs in either the stability control
or the traction control system, you may
experience the following conditions:•
The stability and traction control light
illuminates steadily.
• The stability control and traction control
systems do not enhance your vehicle's
ability to maintain traction of the wheels.
If a driving condition activates either the
stability control or the traction control system
you may experience the following conditions:
• The stability and traction control light
flashes.
• Your vehicle slows down.
• Reduced engine power.
• A vibration in the brake pedal.
• The brake pedal is stiffer than usual.
• If the driving condition is severe and your
foot is not on the brake, the brake pedal
may move as the system applies higher
brake force.
The stability control system has several
features built into it to help you maintain
control of your vehicle:
187
Navigator (TB5) Canada/United States of America, enUSA, First Printing Stability Control

Electronic Stability Control
The system enhances your vehicle
’s ability
to prevent skids or lateral slides by applying
brakes to one or more of the wheels
individually and, if necessary, reducing
engine power.
Roll Stability Control
The system enhances your vehicle ’s ability
to prevent rollovers by detecting your
vehicle ’s roll motion and the rate at which it
changes by applying the brakes to one or
more wheels individually.
Traction Control
The system enhances your vehicle ’s ability
to maintain traction of the wheels by
detecting and controlling wheel spin. See
Using Traction Control (page 185). Vehicle without stability control
skidding off its intended route.

USING HILL DESCENT CONTROL
Principle of Operation
WARNINGS
Hill descent control cannot control
descent in all surface conditions and
circumstances, such as ice or extremely
steep grades. Hill descent control is a driver
assist system and cannot substitute for good
judgment by the driver. Failure to do so may
result in loss of vehicle control, crash or
serious injury. Hill descent control does not provide
hill hold at 0 mph (0 km/h). When
stopped, the parking brake must be applied
or the vehicle must be placed in park (P) or
it may roll away. Hill descent control allows the driver to set
and maintain vehicle speed while
descending steep grades in various surface
conditions.
Hill descent control can maintain vehicle
speeds on downhill grades between
3 mph
(5 km/h) and 20 mph (32 km/h). Above
20 mph (32 km/h), the system remains
armed, but descent speed cannot be set or
maintained.
Hill descent control requires a cooling down
interval after sustained use. The amount of
time that the feature can remain active
before cooling varies with conditions. The
system provides a warning in the message
center and a chime sounds when the system
is about to disengage for cooling. At this
time, manually apply the brakes to maintain
descent speed. Using Hill Descent Control Press and release the hill descent
button in the center of the terrain
management control. The button
illuminates and a chime sounds when you
switch this feature on.
To increase descent speed, press the
accelerator pedal until you reach the desired
speed. To decrease descent speed, press
the brake pedal until you reach the desired
speed.
Whether accelerating or decelerating, once
you reach the desired descent speed,
remove your feet from the pedals and hill
descent control maintains the chosen vehicle
speed.
Note: You may observe noise from the ABS
pump motor during hill descent control
operation. This is a normal characteristic of
the ABS and should be no reason for
concern.

PRINCIPLE OF OPERATION
WARNINGS
To help avoid personal injury, please
read and understand the limitations of
the system as contained in this section.
Sensing is only an aid for some (generally
large and fixed) objects when moving on a
flat surface at parking speeds. Certain
objects with surfaces that absorb ultrasonic
waves, surrounding vehicle's parking aid
systems, traffic control systems, fluorescent
lamps, inclement weather, air brakes, and
external motors and fans may also affect the
function of the sensing system; this may
include reduced performance or a false
activation. To help avoid personal injury, always
use caution when in reverse (R) and
when using the sensing system. WARNINGS
This system is not designed to prevent
contact with small or moving objects.
The system is designed to provide a warning
to assist the driver in detecting large
stationary objects to avoid damaging your
vehicle. The system may not detect smaller
objects, particularly those close to the
ground. Certain add-on devices such as large
trailer hitches, bike or surfboard racks
and any device that may block the normal
detection zone of the system, may create
false beeps. Note:
Keep the sensors, located on the
bumper or fascia, free from snow, ice and
large accumulations of dirt. If the sensors
are covered, the system’ s accuracy can be
affected. Do not clean the sensors with sharp
objects.
Note: If your vehicle sustains damage to the
bumper or fascia, leaving it misaligned or
bent, the sensing zone may be altered
causing inaccurate measurement of
obstacles or false alarms. Note:
The sensing system cannot be turned
off when a MyKey is present. See Principle
of Operation (page 54).
Note: If you attach certain add-on devices
such as a trailer or bike rack, the rear
sensing system may detect that add-on
device and therefore provide warnings. It is
suggested that you disable the rear sensing
system when you attach an add-on device
to your vehicle to prevent these warnings.
The sensing system warns the driver of
obstacles within a certain range of your
vehicle. The system turns on automatically
whenever you switch the ignition on. You can turn the system on or off
by pressing the parking aid button.
If your vehicle does not have a
parking aid button, the system can be
switched off through the information display
menu or from the pop-up message that
appears once you shift the transmission into
reverse (R).
See General Information (page
102).
If a fault is present in the system, a warning
message appears in the information display.
See
Information Messages (page 108).
