•The ABS system activates for more than
approximately a half second
•In the event of sudden braking while the
vehicle is moving at speeds above approx-
imately 6 mph (10 km/h)
When the vehicle has come to a stop, the brake
lights and additional taillights remain on for as
long as the brake pedal is depressed or until
braking force on the vehicle is reduced.
Power brakes function only when the
engine is running
The power brakes utilize vacuum pressure
which is only created when the engine is run-
ning. Never let the vehicle roll to a stop with the
engine switched off.
If the power brakes are not working, consider-
ably higher pressure will be required on the
brake pedal to compensate for the lack of
power assistance. This can happen for exam-
ple when towing your vehicle or if the engine is
switched off when the vehicle is rolling. The
brake pedal feels harder than usual.
Water on brake discs and brake pads
affects braking
Driving in rain and slush or passing through an
automatic car wash can cause water to collect
on the brake discs and pads. This will cause a
delay in braking effect when the pedal is
depressed. To avoid such a delay when thebrakes are needed, depress the pedal occa-
sionally when driving through rain, slush, etc.
This will remove the water from the brakes.
Check that brake application feels normal. This
should also be done after washing or starting
in very damp or cold weather.
Severe strain on the brake systemThe brakes will be subject to severe strain
when driving in mountains or hilly areas, or
when towing a trailer. Vehicle speed is usually
slower, which means that the cooling of the
brakes is less efficient than when driving on
level roads. To reduce the strain on the brakes,
shift into a lower gear and let the engine help
with the braking. Do not forget that if you are
towing a trailer, the brakes will be subjected to
a greater than normal load.
Anti-lock braking system (ABS)The Anti-lock Braking System (ABS) helps to
improve vehicle control (stopping and steering)
during severe braking conditions by limiting
brake lockup. When the system "senses"
impending lockup, braking pressure is auto-
matically modulated in order to help prevent
lockup that could lead to a skid.
The system performs a brief self-diagnostic
test when the engine has been started and
driver releases the brake pedal. Another auto-
matic test may be performed when the vehicle
first reaches a speed of approximately 6 mph(10 km/h). The brake pedal will pulsate several
times and a sound may be audible from the
ABS control module, which is normal.
Cleaning the brake discsCoatings of dirt and water on the brake discs
may result in delayed brake function. This delay
is minimized by cleaning the brake linings.
Cleaning the brake pads is advisable in wet
weather, prior to long-term parking, and after
the vehicle has been washed. Do this by brak-
ing gently for a short period while the vehicle is
moving.
Emergency Brake AssistanceEBA is designed to provide full brake effect
immediately in the event of sudden, hard brak-
ing. The system is activated by the speed with
which the brake pedal is depressed.
When the EBA system is activated, the brake
pedal will go down and pressure in the brake
system immediately increases to the maximum
level. Maintain full pressure on the brake pedal
in order to utilize the system completely. EBA
is automatically deactivated when the brake
pedal is released.

NOTE
•When the EBA system is activated, the
brake pedal will go down and pressure
in the brake system immediately increa-
ses to the maximum level. You must
maintain full pressure on the brake
pedal in order to utilize the system com-
pletely. There will be no braking effect if
the pedal is released. EBA is automati-
cally deactivated when the brake pedal
is released.
•When the vehicle has been parked for
some time, the brake pedal may sink
more than usual when the engine is
started. This is normal and the pedal will
return to its usual position when it is
released.

Electric parking brake
An electric parking brake has the same func-
tion as a manual parking brake.
NOTE
•A faint sound from the parking brake's
electric motor can be heard when the
parking brake is being applied. This
sound can also be heard during the
automatic function check of the parking
brake.
•The brake pedal will move slightly when
the electric parking brake is applied or
released.
Low battery voltageIf the battery voltage is too low, the parking
brake cannot be applied or released. Connect
an auxiliary battery if the battery voltage is too
low, see page 114.
Applying the electric parking brake
Parking brake control
1. Press firmly on the brake pedal.
2. Push the control.
>
The
symbol in the instrument
panel flashes while the parking bake is
being applied, and glows steadily when
the parking brake has been fully applied.
3. Release the brake pedal and ensure that
the vehicle is at a standstill.
4. When the vehicle is parked, the gear selec-
tor must be in position P.
NOTE
•In an emergency the parking brake can
be applied when the vehicle is moving
by holding in the control. Braking will be
interrupted when the accelerator pedal
is depressed or the control is released.
•An audible signal will sound during this
procedure if the vehicle is moving at
speeds above 6 mph (10 km/h).
Parking on a hill
•If the vehicle is pointing uphill, turn the front
wheels so that they point away from the
curb.
•If the vehicle is pointing downhill, turn the
front wheels so that they point toward the
curb.
The parking brake should also be applied.

•For safety reasons, the parking brake is
only released automatically if the engine
is running and the driver is wearing a seat
belt.
•The electric parking brake will be
released immediately when the acceler-
ator pedal is pressed and the gear selec-
tor is in position D or R.
2. Fasten the seat belt.
3.
Move the gear selector to position D or R
and press the accelerator pedal. The park-
ing brake will release when the vehicle
begins to move.
Heavy load uphillA heavy load, such as a trailer, can cause the
vehicle to roll backward when the parking
brake is released automatically on a steep
incline. To help avoid this:
1. Keep the electric parking brake lever
pushed in with the left hand while shifting
into Drive with the right.
2. While pressing the throttle pedal to pull
away, release the parking brake lever only
after the vehicle begins to move.

Hill Descent Control (HDC)*
03

* Option/accessory, for more information, see Introduction.125 Introduction
Normally, when the accelerator pedal is
released while driving down hills, the vehicle's
speed slows as the engine runs at lower rpm
(the normal engine braking effect). However, if
the downhill gradient becomes steeper and if
the vehicle is carrying a load, speed increases
despite the engine braking effect. In this situa-
tion, the brakes must be applied to reduce the
vehicle's speed.
HDC is a type of automatic engine brake and
makes it possible to increase or decrease the
vehicle's speed on downhill gradients using
only the accelerator pedal, without applying
the brakes. The brake system functions auto-
matically to maintain a low and steady speed.
HDC is particularly useful when driving down
steep hills with rough surfaces, and where the
road may have slippery patches.
WARNING
HDC does not function in all situations, and
is a supplementary braking aid. The driver
has full responsibility for driving in a safe
manner.
Function
•HDC can be switched on and off with the
button in the center console. An indicator
light in the button illuminates when HDC is
activated.
•The indicator light in the instrument
panel illuminates and a message is dis-
played when the system is controlling the
vehicle's speed.
•HDC only functions when first or reverse
gears are selected (1 will be shown in the
instrument panel display when first gear is
selected).
NOTE
HDC cannot be activated if the gear selector
is the D position.
Using HDC
HDC allows the car to roll forward at a maxi-
mum speed of 6 mph (10 km/h), and 4 mph
(7 km/h) in reverse. However, the accelerator
pedal can be used to select any speed that is
possible in first or reverse gears. When the
accelerator pedal is released, speed is quickly
reduced again to 6 mph (10 km/h) or 4 mph
(7 km/h), depending on the gear selected,
regardless of the hill's gradient. It is not nec-
essary to apply the brakes.
•The brake lights illuminate automatically
when HDC is controlling the vehicle's
speed.
•The driver can slow or stop the vehicle at
any time by applying the brakes.
HDC is deactivated when:
•The button on the center console is
pressed
•A gear higher than first gear is selected
•D is selected on vehicles with an automatic
transmission
HDC can be deactivated at any time. If this is
done while driving down a steep hill, the sys-
tem's braking effect will decrease gradually.

Adaptive Cruise Control (ACC)*
04

* Option/accessory, for more information, see Introduction.155
WARNING
•Adaptive Cruise Control is not a colli-
sion avoidance system. The driver is
always responsible for applying the
brakes if the system does not detect
another vehicle.
•Adaptive Cruise Control does not react
to people or animals, or small vehicles
such as bicycles and motorcycles. It
also does not react to slow moving,
parked or approaching vehicles, or sta-
tionary objects.
•Do not use Adaptive Cruise Control in
demanding driving conditions such as
city driving or other heavy traffic situa-
tions, in slippery conditions, when there
is a great deal of water or slush on the
road, during heavy rain or snow, in poor
visibility, on winding roads or on high-
way on- or off-ramps.
The distance to the vehicle ahead (in the same
lane) is monitored by a radar sensor. Your vehi-
cle's speed is regulated by accelerating and
braking. The brakes may emit a sound when
they are being modulated by the adaptive
cruise control system. This is normal.
WARNING
The brake pedal moves when the adaptive
cruise control system modulates the
brakes. Do not rest your foot under the
brake pedal.
The ACC system is designed to smoothly reg-
ulate speed. However, the driver must apply
the brakes in situations that require immediate
braking. This applies when there are great dif-
ferences in speed between vehicles, or if the
vehicle ahead brakes suddenly.
WARNING
Due to limitations in the radar sensor, brak-
ing may occur unexpectedly or not at all,
see page 159.
Adaptive Cruise Control can be put in active
mode at any permitted speed. However, if the
vehicle's speed falls below 18 mph (30 km/h)
or if engine speed (rpm) becomes too low, ACC
disengages (goes into standby mode) and will
no longer modulate the brakes
2. The driver will
then have to maintain a safe distance to the
vehicle ahead.
WARNING
When Adaptive Cruise Control is in standby
mode or is switched off completely, the
brakes will not be modulated automatically.
The driver must assume full control over the
vehicle.
Warning light—driver braking requiredAdaptive Cruise Control can exert brake force
that is equivalent to approximately 40% of the
vehicle's total braking capacity. In situations
requiring more brake force than ACC can pro-
vide and if the driver does not apply the brakes,
an audible signal from the Collision Warning
system will sound and warning light will illumi-
nate (see page 173) in the windshield to alert
the driver to react.
NOTE
Strong sunlight, reflections, extreme light
contrasts, the use of sunglasses, or if the
driver is not looking straight ahead may
make the visual warning signal in the wind-
shield difficult to see.
2Does not apply to vehicles with the optional Queue Assist. See page 158 for more information.
