Brakes
If a brake circuit fails (see "Brake sys
tem faults", page 164),
 you must press the brake pedal further
down to achieve the same effect,
 the braking distance is longer.
쮿 Immediately park your car away from
moving traffic.
쮿 Secure your car against rolling away if
you have to leave it.
쮿 Do not drive any further.
쮿 Call a breakdown recovery service
such as smartmove Assistance or a
qualified specialist workshop such as
a smart center.
>Note!
The brake servo will function only with
the engine switched on.
The mechanicalacoustic brake pad
display
The car is equipped with a mechanical
acoustic brake pad display. If you can
hear a continuous noise from the front
axle when braking, you should take the
car to a qualified specialist workshop,
e.g. a smart center.
Hydraulic brake assistant
The hydraulic brake assistant is activat
ed in emergency braking situations.
When you quickly depress the brake pedal
(but without applying sufficient force),
the hydraulic brake assistant automati
cally amplifies the brake force, thereby
decreasing the braking distance.
쮿 Depress and hold the brake pedal until
the emergency braking situation has
passed.
> abs will prevent the wheels from
locking up.
> When you release the brake pedal, the
brakes will function as they normal
ly would.
> The hydraulic brake assistant is
then deactivated.
Accident risk!
In the event of the car needing to
be towed, a significantly greater
amount of pedal pressure will be re
quired when the engine is switched off.
