Start assistance HSAThe foot brake can also be released on an uphill
gradient to start the engine automatically - the
HSA function means that the car does not roll
backwards.
HSA (Hill Start Assist) means that the pressure
in the brake system remains temporarily avail-
able while the driver moves his/her foot from
the brake pedal to the accelerator pedal for
driving off with the engine having stopped
automatically. The temporary braking effect
releases after a couple of seconds or when the
driver accelerates.
There is more information available on HSA on
page 120.
Gear indicator1
An essential detail in connection with environ-
mental driving is to drive in the right gear and
change gear in time.
The driver is assisted by an indicator which
notifies the driver when it is most advanta-
geous to engage the next higher or lower gear
- GSI (Gear Shift Indicator).
Indication is made with an up or down arrow in
the combined instrument panel's right-hand
display.
Deactivating the Start/Stop functionIn certain situations, it may
advisable to temporarily
switch off the automatic
Start/Stop function - this is
carried out by pressing this
button once, at which point
the button's lamp goes out.
Disengaged Start/Stop func-
tion is indicated by the infor-
mation display's symbol
going out and the message
Auto Start-Stop OFF being
displayed for
about 5 seconds - while the
button's lamp goes out at the
same time.
The Start/Stop function is disengaged until it is
reactivated with the button or until the next
time the engine is started with the key.
Limitations
The engine does not auto-stopEven if the Start/Stop function is activated, the
engine does not stop automatically if:
ConditionsM/AA
the driver has opened the seat-
belt's buckle.A
the car does not stop completely.
the capacity of the battery is
below the minimum permissible
level.
the engine does not have normal
operating temperature.
outside temperature is below
freezing point or above
approx. 30 °C.

131 General
The car is equipped with two brake circuits. If
one brake circuit is damaged then this will
mean that the brakes engage at a deeper level
and harder pressure on the pedal is needed to
produce the normal braking effect.
The driver's brake pedal pressure is assisted
by a brake servo.
WARNING
The brake servo only works when the engine
is running.
If the brake is used when the engine is switched
off then the pedal will feel stiff and more force
must be used to brake the car.
In very hilly terrain or when driving with a heavy
load the brakes can be relieved by using engine
braking. Engine braking is most efficiently used
if the same gear is used downhill as up.
For more general information on heavy loads
on the car, see page 359.
Anti-lock braking systemThe car is equipped with ABS (Anti-lock
Braking System) which prevents the wheels
from locking during braking. This means the
ability to steer is maintained and it is easier to
swerve to avoid a hazard for example. Vibrationmay be felt in the brake pedal when this is
engaged and this is normal.
A short test of the ABS system is made auto-
matically after the engine has been started
when the driver releases the brake pedal. A
further automatic test of the ABS system may
be made when the car reaches 10 km/h. The
test may be experienced as pulses in the brake
pedal.
Emergency brake lights and automatic
hazard warning flashers
Emergency brake lights are activated to alert
vehicles behind about sudden braking. The
function means that the brake light flashes
instead of - as in normal braking - shining with
a constant glow.
Emergency brake lights are activated at
speeds above 50 km/h if the ABS system is
working and/or in the event of sudden braking.
After the car's speed has been slowed below
10 km/h the brake light returns from flashing to
the normal constant glow - while at the same
time the hazard warning flashers are activated,
and they flash until the driver changes engine
speed with the accelerator pedal or they are
deactivated with their button, see page 91.
Cleaning the brake discsCoatings of dirt and water on the brake discs
may result in delayed brake function. This delay
is minimised by cleaning the brake linings.
Manual cleaning is advisable with wet road sur-
faces, prior to long-stay parking and after the
car has been washed. Carry this out by braking
gently during a short period while en route.
Emergency Brake AssistanceEmergency Brake Assistance EBA (Emergency
Brake Assist) helps to increase brake force and
so reduce braking distance. EBA detects the
driver's braking style and increases brake force
as necessary. The brake force can be rein-
forced up to the level when the ABS system is
engaged. The EBA function is interrupted when
the pressure on the brake pedal is reduced.
NOTE
When EBA is activated the brake pedal low-
ers slightly more than usual, depress (hold)
the brake pedal as long as necessary. If the
brake pedal is released then all braking
ceases.
