GENERAL INFORMATION
Note:
Occasional brake noise is normal. If
a metal-to-metal, continuous grinding or
continuous squeal sound is present, the
brake linings could be worn-out, you should
have them checked. If the vehicle has
continuous vibration or shudder in the
steering wheel while braking, you should
have the system checked.
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 Wheels
(page 403). See
Warning Lamps and
Indicators (page 129).
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. Switch
the engine off, move the transmission to park
(P) and apply the parking brake. Inspect the
accelerator pedal and the area around it for
any items or debris that may be obstructing
its movement. If none are found and the
condition persists, do not drive your vehicle.
Have your vehicle towed to the location you
are having it checked.
Emergency Brake Assist
Emergency brake assist detects when you
brake heavily by measuring the rate at which
you press the brake pedal. It provides
maximum braking efficiency as long as you
press the pedal. Emergency brake assist
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 switch the ignition on.
If the light does not illuminate
during start up, remains on or flashes, the
anti-lock braking system may be disabled.
Have the system checked. If the anti-lock
brake system is disabled, normal braking is
still effective. If the brake warning lamp
illuminates with the parking brake
released, have your brake system
serviced immediately.
It also illuminates momentarily when you
switch the ignition on to confirm the lamp is
functional. If it does not illuminate when you
switch the ignition on, or begins to flash at
any time, have the system checked.

HINTS ON DRIVING WITH ANTI-
LOCK BRAKES
The anti-lock braking system does 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.
Note: If the system activates, 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.
ELECTRIC PARKING BRAKE WARNING: Always fully apply the
parking brake and make sure you shift into

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.

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.

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.
See
Information Messages (page 139).

PRINCIPLE OF OPERATION
WARNING: To help avoid personal
injury, always use caution when in reverse
(R) and when using the sensing system. WARNING:
The system may not
detect objects with surfaces that absorb
reflection. Always drive with due care and
attention. Failure to take care may result
in a crash. WARNING:
Traffic control systems,
inclement weather, air brakes, external
motors and fans may affect the correct
operation of the sensing system.This may
cause reduced performance or false alerts. WARNING:
The system may not
detect small or moving objects, particularly
those close to the ground. Note:
Certain add-on devices installed
around the bumper or fascia may create
false beeps. For example, large trailer
hitches, bike or surfboard racks, license plate
brackets, bumper covers or any other device
that may block the normal detection zone
of the system.
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. See your
authorized technician.
Note: When a trailer is connected to your
vehicle, the rear parking aid may detect the
trailer and therefore provide warnings.
Disable the rear parking aid when a trailer
is connected to prevent these warnings. Note:
The sensing system cannot be turned
off when a MyKey is present. See Principle
of Operation
(page 79).
We recommend that you take some time to
get to know the system and its limitations by
reading this section.
The sensing system warns the driver of
obstacles within a certain range of your
vehicle. The system automatically turns on
each time you switch the ignition on.
When receiving a detection warning, the
radio volume reduces to a predetermined
level. After the warning goes away, the radio
volume returns to the previous level. 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
134).
