BRAKE PRECAUTIONS

WARNING: Driving your vehicle with

the warning lamp on is dangerous. A
significant decrease in braking
performance may occur. It may take you
longer to stop your vehicle. Have your
vehicle checked as soon as possible.
Driving extended distances with the
parking brake engaged can cause brake
failure and the risk of personal injury.

Wet brakes result in reduced braking
efficiency. Gently press the brake pedal a
few times when leaving a car wash or driving
from standing water to dry the brakes.

Note: Depending on applicable laws and
regulations in the country for which your
vehicle was originally built, the stoplamps
could flash during heavy braking. Following
this the hazard warning flashers could also
turn on when your vehicle comes to a stop.

ANTI-LOCK BRAKING SYSTEM

ANTI-LOCK BRAKING SYSTEM
LIMITATIONS

The anti-lock braking system does not
eliminate the risk of crash 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 could pulse and travel further.
Maintain pressure on the brake pedal.

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.

LOCATING THE BRAKE FLUID
RESERVOIR

See Under Hood Overview (page 415).

CHECKING THE BRAKE FLUID

WARNING: Do not use any fluid other

than the recommended brake fluid as this
will reduce brake efficiency. Use of
incorrect fluid could result in the loss of
vehicle control, serious personal injury or
death.

233

Brakes

WARNING: Only use brake fluid from

a sealed container. Contamination with dirt,
water, petroleum products or other
materials may result in brake system
damage or failure. Failure to adhere to this
warning could result in the loss of vehicle
control, serious personal injury or death.

WARNING: Do not allow the fluid to

touch your skin or eyes. If this happens,
rinse the affected areas immediately with
plenty of water and contact your physician.

WARNING: The brake system could

be affected if the brake fluid level is below
the MIN mark or above the MAX mark on
the brake fluid reservoir.

E170684

1. Park your vehicle on a level surface.

2. Look at the brake fluid reservoir to see

where the brake fluid level is relative to
the MIN and the MAX marks on the
reservoir.

Note: To avoid fluid contamination, the
reservoir cap must remain in place and fully
tight, unless you are adding fluid.

Only use fluid that meets our specifications.
See Capacities and Specifications (page
469).

level or a brake system fault. See an
authorized dealer.

BRAKES – FREQUENTLY ASKED
QUESTIONS

Is it normal for my brakes to make noise?

Occasional brake noise is normal. If a
metal-to-metal, continuous grinding, or
continuous squeal sound is present, the
brake lining could be worn-out. Have
the system checked by an authorized
dealer.

There is an electrical motor sound when I
press on the brake pedal or activate the
park brake switch. Is this normal?

Yes, those sounds are the electronic
brake booster or the electronic park
brake operating.

Note: Brake dust could accumulate on the
wheels, even under normal driving
conditions. Some dust is normal as the
brakes wear and does not contribute to
brake noise. See Cleaning Wheels (page
431).

Electric Parking Brake

WHAT IS REVERSE BRAKING
ASSIST

The system uses sensors on the rear of your
vehicle to detect a possible collision and
applies the brakes to either reduce the
damage from impact, or to assist in avoiding
the collision.

HOW DOES REVERSE BRAKING
ASSIST WORK

Reverse Braking Assist functions when in
reverse (R) and traveling at a speed of
1–7 mph (1.5–12 km/h).

If the system detects an obstacle behind your
vehicle, it provides a warning through the
rear parking aid or cross traffic alert system.

REVERSE BRAKING ASSIST
PRECAUTIONS

WARNING: You are responsible for

controlling your vehicle at all times. The
system is designed to be an aid and does
not relieve you of your responsibility to
drive with due care and attention. Failure
to follow this instruction could result in the
loss of control of your vehicle, personal
injury or death.

WARNING: To help avoid personal

injury, always use caution when in reverse
(R) and when using the sensing system.

WARNING: The system may not

operate properly during severe weather
conditions, for example snow, ice, heavy
rain and spray. Always drive with due care
and attention. Failure to take care may
result in a crash.

WARNING: Traffic control systems,

fluorescent lamps, 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: Some situations and

objects prevent hazard detection. For
example low or direct sunlight, inclement
weather, unconventional vehicle types, and
pedestrians. Apply the brakes when
necessary. Failure to follow this instruction
could result in the loss of control of your
vehicle, personal injury or death.

WARNING: Do not use the system

with accessories that extend beyond the
front or rear of your vehicle, for example a
trailer hitch or bike rack. The system is not
able to make corrections for the additional
length of the accessories.

239

Reverse Braking Assist

The system only applies the brakes for a
short period of time when an event occurs.
Act as soon as you notice the brakes apply
in order to remain in control of the vehicle.
If you do not intervene the vehicle may start
to move again.

Note: Certain add-on devices around the
bumper or fascia may create false alerts. For
example, large trailer hitches, bicycle or
surfboard racks, license plate brackets,
bumper covers or any other device that may
block the normal detection zone of the
system. Remove the add-on device to
prevent false alerts.

Note: The system does not react to small or
moving objects, particularly those close to
the ground.

Note: The system does not operate during
hard acceleration or steering.

Note: If your vehicle sustains damage to the
bumper or fascia leaving it misaligned or
bent, it could alter the sensing zone causing
inaccurate measurement of obstacles or
false alerts.

Note: Vehicle loading and suspension
changes can impact the angle of the sensors
and may change the normal detection zone
of the system resulting in inaccurate
measurement of obstacles or false alerts.

Note: When you connect a trailer, the system
may detect the trailer and provide an alert,
or the system turns off. If the system does
not turn off, switch the system off manually
after you connect the trailer.

Note: You may experience reduced system
performance on road surfaces that limit
deceleration. For example, roads with ice,
loose gravel, mud or sand.

SWITCHING REVERSE BRAKING
ASSIST ON AND OFF

1. Press Features on the touchscreen.
2. Press Driver Assistance.

3. Switch Reverse Brake Assist on or off.

Note: The system is unavailable when the
rear parking aid, cross traffic alert or traction
control is off.

Note: If your vehicle is not equipped with
cross traffic alert the reverse braking assist
relies on input from the rear parking aid and
rear camera sensors.

Note: The default setting is on in some
regions.

OVERRIDING REVERSE BRAKING
ASSIST

There could be instances when unexpected
or unwanted braking occurs. Firmly pressing
the accelerator pedal or switching the feature
off overrides the system.

REVERSE BRAKING ASSIST

WHAT IS HILL START ASSIST

Hill Start Assist makes it easier for you to pull
away when your vehicle is on a slope without
using the parking brake.

HOW DOES HILL START ASSIST
WORK

When the system activates, your vehicle
remains stationary for a few seconds after
you release the brake pedal. This gives you
time to move your foot from the brake pedal
to the accelerator pedal. The brakes release
when the engine has developed sufficient
torque to prevent your vehicle from rolling
down the slope.

HILL START ASSIST PRECAUTIONS

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

WHAT IS TRACTION CONTROL

The traction control system helps to avoid
drive wheel spin and loss of traction.

HOW DOES TRACTION CONTROL
WORK

If your wheels begin to spin, the loss of
traction can compromise steering control
and stability of the vehicle. The traction
control system applies the brakes to
individual wheels and when needed, reduces
engine power at the same time to increase
traction.

SWITCHING TRACTION CONTROL
ON AND OFF

WARNING: 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.
