Brakes and brake servo sys-
tems
Introduction
WARNING
●
The brake serv
o only works when the en-
gine is running. Braking when the engine is
switched off requires applying more
strength to the brake pedal. Risk of acci-
dent!
●
Press down on the clutch pedal when
stopping and braking with a manual gear-
box, petrol engine vehicle at low speed.
Otherwise, the brake servo might not work
properly. Risk of accident!
●
In the event of damage to the standard
front spoiler or where a different front
spoiler, wheel trims, etc. are subsequently
fitted, make sur
e the air vent to the brakes
on the front wheels is not blocked. Other-
wise, braking operations may be impaired.
Risk of accident!
●
Always fully release the handbrake. If it is
only partially released, this will cause
overheating of the rear brakes, which can
impair the function of the brake system.
Risk of accident!
●
Never leave children unsupervised in the
vehicle. They could release the handbrake
or move the gear lever. The vehicle could
start moving. Risk of accident!
●
Insufficient fuel can cause the engine to
run irregularly or to switch off. Brake assist
systems could be impaired. Risk of acci-
dent!
●
Always adjust your driving style to suit
visibility, the weather and road and traffic
conditions. The best vehicle safety offered
by brake assist systems must never encour-
age you to run greater risks. Risk of acci-
dent!
CAUTION
●
Observe the information concerning ne
w
brake pads
›››
page 210.
●
Where braking is not necessary, do not
wear down the brake pads by pressing
down gently on the brake pedal. This cau-
ses the brakes to overheat, increasing their
wear and increasing braking distances.
●
To ensure the br
ake assist systems work
properly, all wheels must be fitted with
tyres approved by the manufacturer.
Note
●
If you br
ake suddenly and the br
ake sys-
tem control unit regards the situation as
hazardous for the drivers behind you, the
brake lights will begin to flash automatical-
ly. After reducing speed to approximately
10 km/h (6 mph) or stopping the vehicle,
the brake lights will stop flashing and the
hazard warning lights will switch on. The
hazard warning lights are automatically
switched off when you accelerate or re-
start the vehicle.
●
On long, steep gradients, reduce your
speed and change to a lower gear (manual
gearbox) or move the selector lever to a
lower gear position (automatic gearbox).
This uses the force of the engine and the
brakes do not suffer as much. If you still
have to brake, do so intermittently, press-
ing down repeatedly on the brake pedal.
●
Vehicle modifications (e.g. to the engine,
brakes, frame or a combination of wheels
and tyres) could impair the brake assist
systems

modifications to the vehicle.
●
In the event of a fault in the ABS system,
the ESC, TCS and EDL are switched off au-
tomatically. A fault in the ABS is indicated
by the
