● When mov in
g with the engine switched off,
the ignition key must always remain in posi-
tion 2
››› Fig. 172 ›
›› page 154 (ignition on).
The control lamps will light up in this posi-
tion. Otherwise, the steering lock could en-
gage suddenly. Risk of accident!
● Do not remove the key from the ignition un-
til the
vehicle has come to a standstill and is
secure (e.g. the handbrake is engaged). Oth-
erwise, the steering lock could suddenly en-
gage. Risk of accident!
● Always take the ignition key with you when
you le
ave the vehicle. This is particularly im-
portant if you leave children in the vehicle.
Children could, for example, start the engine
with the subsequent risk of accident.
● Never leave the engine running in unventi-
lated or c
losed rooms. The exhaust gases
contain carbon monoxide, an odourless and
colourless poisonous gas. Risk of fatal acci-
dents! Carbon monoxide can cause people to
lose consciousness and can cause death. ●
Never l e
ave the vehicle unattended if the
engine is running.
● Never switch the engine off until the vehi-
cle h
as come to a complete stop. Risk of acci-
dent! CAUTION
● Turnin g the s
teering wheel fully in either
direction when the vehicle is stationary and
the engine is in gear puts the power steering
under great stress. This could lead to noise.
Never leave the steering wheel turned fully in
either direction for more than 15 seconds.
Risk of damage to the power steering system!
● The starter motor may only be used (key
position 3
››› Fig. 172 ›
›› page 154 in the ig-
nition) if the engine is off. Using the starter
motor when the engine is running could dam-
age it.
● Immediately release the ignition key when
the engine st
arts, otherwise damage could be
caused to the starter motor.
● When the engine is cold, you should avoid
high engine speed
s, driving at full throttle
and over-loading the engine before it reaches
operating temperature. Risk of engine dam-
age!
● Do not tow-start the engine. Risk of engine
damag
e! In vehicles with a catalytic convert-
er, fuel that has not been burned could reach
the catalytic converter and catch fire in it.
This would lead to a fault in the catalytic con-
verter. You may use the battery from another » 153

Brakes and brake servo sys-
tems Introduction WARNING
● The brak e ser
vo 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 accident!
● Press down on the clutch pedal when stop-
ping and brak
ing with a manual gearbox, pet- rol engine vehicle at low speed. Otherwise,
the brak
e ser
vo might not work properly. Risk
of accident!
● In the event of damage to the standard
front s
poiler or where a different front spoil-
er, wheel trims, etc. are subsequently fitted,
make sure the air vent to the brakes on the
front wheels is not blocked. Otherwise, brak-
ing operations may be impaired. Risk of acci-
dent!
● Always fully release the handbrake. If it is
only p
artially released, this will cause over-
heating of the rear brakes, which can impair
the function of the brake system. Risk of acci-
dent!
● Never leave children unsupervised in the
vehicl
e. 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
irregu
larly or to switch off. Brake assist sys-
tems could be impaired. Risk of accident!
● Always adjust your driving style to suit visi-
bility
, the weather and road and traffic condi-
tions. The best vehicle safety offered by
brake assist systems must never encourage
you to run greater risks. Risk of accident! CAUTION
● Ob ser
ve the information concerning new
brake pads ››› page 163.156
Driving
●
Where br ak
ing is not necessary, do not
wear down the brake pads by pressing down
gently on the brake pedal. This causes the
brakes to overheat, increasing their wear and
increasing braking distances.
● To ensure the brake assist systems work
properly, a
ll wheels must be fitted with tyres
approved by the manufacturer. Note
● If y
ou brake suddenly and the brake system
control unit regards the situation as hazard-
ous for the drivers behind you, the brake
lights will begin to flash automatically. 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 restart the vehicle.
● On long, steep gradients, reduce your
speed and ch
ange 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, pressing down repeatedly
on the brake pedal.
● Vehicle modifications (e.g. to the engine,
brake
s, frame or a combination of wheels and
tyres) could impair the brake assist systems
››› page 193, Accessories and modifications
to the vehicle . ●
In the event of
a fault in the ABS system,
the ESC, TCS and EDL are switched off auto-
matically. A fault in the ABS is indicated by
the ››› page 101 warning lamp. Brakes
Wear
The rat
e of
wear of the brake pads depends
on the driving style and on the way in which
the vehicle is used. The brake pads will wear
more quickly if you use your vehicle frequent-
ly in urban traffic and short trips or drive in a
sporty style. Under these demanding condi-
tions, visit your specialised service, even be-
fore the scheduled service date, so that the
thickness of the brake pads can be meas-
ured.
Wet roads or road salt
If brakes are wet or frozen, or if you are driv-
ing on roads which have been gritted with
salt, braking power may set in later than nor-
mal. Dry the brakes as soon as possible by
braking repeatedly.
Corrosion
Long periods of inactivity and little use can
lead to rust on the brake discs and dirt on the
brake pads. Where the brake system is sub-
jected to light stress or in the case of corro- sion, clean the brake discs by braking fully
sever
al
times at a high speed.
Brake system fault
If you notice that the braking distance sud-
denly increases and the brake pedal can be
pressed down more fully, there may be a fault
in the brake system. Visit a specialised serv-
ice immediately and adjust your driving style
to the extent of the damage and to limit the
effect of the brakes.
Low brake fluid level
Insufficient brake fluid could cause faults in
the brake system. The brake fluid level is con-
trolled electronically ››› page 99, Brake sys-
tem .
Brake servo
The brake servo supplements the pressure
you exert on the brake pedal. The brake servo
only works when the engine is running.
