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

The m
anual gearbox can be activated when
the vehicle is either moving or stationary.
When accelerating, the gearbox automatical-
ly shifts up shortly before the maximum en-
gine speed is reached.
On shifting up, the gear is only engaged
when there is no risk of engine damage.
When the accelerator pedal is pressed down
to the kick-down zone, the gearbox will shift
down in line with the road speed and engine
speed. Note
The kick-down function is also available in
manua l
shift mode. Selector lever lock

the brake to unlock it. Remember, if the se-
lector lever is in positions P and N then thewarning lamp will light up on the general in-
strument p
anel ››› page 104.
When the selector lever merely moves
through position N (e.g. when moved from R
to D), the lever lock is not applied. This
makes it possible, for example, to rock a
stuck vehicle backwards and forwards. The
lock is only applied if the brake is not press-
ed and the selector lever is moved to position
N for more than 2 seconds.
The selector lever only locks when the is vehi-
cle stationary or driving at a speed lower
than 5 km/h (3 mph). At a higher speed, it
automatically disconnects in the N position.

The interlock button on the selector lever
knob prevents the driver from inadvertently
engaging a gear. Press the button to unlock
the selector lever.
