Note:
The AdvanceTrac® with RSC® stability
enhancement system can be switched off
by deselecting the feature on the instrument
panel. See Using Traction Control (page
247). This disables the engine management
feature, allowing the vehicle to maintain full
power and enhanced momentum through
the obstacle.
Note: The AdvanceTrac system can take
control of the transfer case clutch and
disable it during driving maneuvers when
necessary.
2H - 4X2
This turns on when you select normal or
conserve. Power is delivered to the rear
wheels only. This mode is appropriate for
normal on-road driving on dry pavement and
provides the best fuel economy. 4A - 4X4 Auto
This turns on when you select excite, normal,
4x4 auto or slippery. It provides electronically
controlled four-wheel drive with power
delivered to all four wheels, as required, for
increased traction. 4A is calibrated in
conjunction with drive mode. Using 4A in
excite is less aggressively tuned and is
appropriate for dry road surfaces. Using 4A
in normal and 4x4 auto is appropriate for all
on-road driving conditions, such as dry road
surfaces, wet pavement, light snow or gravel.
Using 4A in slippery is more aggressively
tuned and is appropriate for slippery
surfaces, such as light snow or gravel.
4H - 4X4 High
This turns on when you select deep
conditions. It provides electronically locked
four-wheel drive power to both the front and
rear wheels for use in off-road or winter
conditions such as deep snow, sand or mud.
This mode is not for use on dry pavement.4L - 4X4 Low (If Equipped)
This turns on when you select slow climb. It
provides electronically locked four-wheel
drive power to both the front and rear wheels
for use on low traction surfaces, but does so
with additional gearing for increased torque
multiplication. Intended only for off-road
applications such as deep sand, steep slopes
or pulling heavy objects. Using 4L does not
engage when your vehicle is moving above
3 mph (5 km/h)
. This is normal and is no
reason for concern.
Shifting Between Four-Wheel Drive System
Modes
Note: Momentarily releasing the accelerator
pedal when a shift in progress message
displays improves engagement and
disengagement performance.
Note: Do not perform this operation if the
rear wheels are slipping.
Note: You may hear some noise as the
system shifts or engages, This is normal.

Navigator (TB9) Canada/United States of America, enUSA, First-Printing Four-Wheel Drive
(If Equipped)

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.

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.

HILL START ASSIST
WARNING: 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) for automatic transmission or first gear
for manual transmission. WARNING: You must remain in your
vehicle when the system turns on. At all
times, you are responsible for controlling
your vehicle, supervising the system and
intervening, if required. Failure to take care
may result in the loss of control of your
vehicle, serious personal injury or death.
Note: 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. 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 134). 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,
drive (D) or 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 134). The system
remembers the last setting when you start
your vehicle.
244
Navigator (TB9) Canada/United States of America, enUSA, First-Printing Brakes

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.
AUTO HOLD
WARNING: The system does not
replace the parking brake. When you leave
your vehicle, always apply the parking
brake. WARNING: You must remain in your
vehicle when the system turns on. At all
times, you are responsible for controlling
your vehicle, supervising the system and
intervening, if required. Failure to take care
may result in the loss of control of your
vehicle, serious personal injury or death. WARNING:
The system will turn off
if a malfunction is apparent. Failure to take
care may result in the loss of control of
your vehicle, serious personal injury or
death. The system uses your vehicle's brakes to
hold your vehicle at a standstill after you stop
your vehicle and release the brake pedal.
For example, Auto Hold can assist you while
stopping at traffic lights or while in traffic
jams by holding the brake pressure for you
once you bring your vehicle to a stop.
Make sure you switch the system off before
towing with your vehicle.
Note:
In case of a malfunction in the system
while Auto Hold actively holds the vehicle
(for example, low power supply), a message
appears in the information display asking
you to press the brake pedal. If you see this
message, press the brake pedal
immediately.
Note: The system only activates if it
recognizes it is applying enough brake
pressure. On a steep hill or slope, make sure
you press the brake pedal sufficiently to
activate the system. Note:
In some cases, Auto Hold might hand
over to the parking brake. When the parking
brake applies, the red brake lamp appears.
This is normal. When you press the
accelerator pedal, the drive away release
feature releases the parking brake.
Note: Auto Hold works on all road grades. Press the button to switch the system on and
off. The indicator light illuminates when you
switch the system on.
Note:
You can only switch the system on if
you close the door and fasten your seatbelt.
Note: The system turns off every time you
power down your vehicle.
245
Navigator (TB9) Canada/United States of America, enUSA, First-Printing BrakesE256165

Note:
The system remembers the last setting
when you start your vehicle.
Note: When in reverse (R), Auto Hold does
not function.
When the system is off, your vehicle behaves
the same as a vehicle without Auto Hold.
There is an indicator lamp in the instrument
cluster that has two modes, active and
unavailable: The auto hold active indicator
illuminates in the information
display when the system holds
your vehicle stationary. When in active mode,
press the brake pedal and the Auto Hold
button to switch the system off. The auto hold unavailable indicator
illuminates in the information
display when the system is on but
unavailable to hold your vehicle (for example,
during Active Park Assist, Stay in Neutral
Mode, or when you do not fasten your
seatbelt or close the door). Note:
Make sure you switch off Auto Hold
or use the Stay in Neutral mode before you
enter a car wash. See Automatic
Transmission (page 227).
Using Auto Hold
1. Use the brakes to bring your vehicle to a complete stop. The auto hold active
indicator illuminates in the information
display.
2. Release the brake pedal. The system holds your vehicle at a standstill. The
auto hold active indicator remains
illuminated in the information display.
3. When you press the accelerator pedal, the system releases the brakes and you
will be able to drive off. Once you drive
off, the auto hold active indicator no
longer illuminates in the information
display.
Note: The auto-start-stop system (if
equipped) may stop the engine when you
press the brake pedal. If this occurs, it
restarts once you press the accelerator
pedal. Auto Hold still holds your vehicle at
a standstill with the engine off.

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 information
display controls or 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
the 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 On and Off
You can switch traction control on and off
through the information display controls. See
General Information
(page 134).
When you switch the system off, a message
and an illuminated icon appear on the
instrument cluster.
Switch traction control on again to return the
system to normal operations. Note:
Your vehicle may have MyKey
restrictions regarding this feature.
See
Principle of Operation (page 79).
System Indicator Lights and Messages The stability and traction control
light temporarily illuminates on
engine start-up and flashes:
• When a driving condition activates either
of the systems.
• If a problem occurs in either of the
systems. The stability and traction control
off light temporarily illuminates on
engine start-up and stays on when
you switch the traction control system off.

PRINCIPLE OF OPERATION
WARNING: 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 allows you to set and
maintain vehicle speed when descending
steep grades in various surface conditions.
Hill descent control can maintain vehicle
speeds on downhill grades between
0 mph
(3 km/h) and 20 mph (32 km/h). Above
20 mph (32 km/h), the system remains
armed, but you cannot use the system to set
or maintain the descent speed. Hill descent control requires a cooling down
interval after a period of 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 tone sounds when
the system is about to disengage for cooling.
At this time, manually apply the brakes as
needed to maintain descent speed.
USING HILL DESCENT CONTROL
You can switch the hill descent
control on and off through the
information display.
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.
Hill Descent Modes
• At speeds between
2 mph (3 km/h) and
20 mph (32 km/h): Your vehicle maintains
the speed you desire while in this mode.
• At speeds between
20 mph (32 km/h)
and 40 mph (64 km/h): Your vehicle does
not maintain the speed you desire and
you cannot set your descent speed.
• At speeds above 40 mph (64 km/h): You
need to switch this feature back on to
use.
Refer to the Information Display for additional
hill descent control messages.
