Brake assist
Rapid powerful application of the brake
pedal automatically applies maximum
brake force amplification to achieve the
shortest possible braking distance under
full braking (brake assist).
Maintain steady pressure on the brake
pedal for as long as full-on braking is to
continue. When the brake pedal is
released, the maximum brake force
amplification is taken away.
Foot brake
The brake system comprises two separate
brake circuits.
If one brake circuit should fail, the vehicle
can still be braked with the second
remaining circuit.
If this happens, the brake pedal must be
fully depressed with greater pedal
pressure. The distance required for braking
will be greater.
If, at any time during driving, the brake
pedal can be depressed further than
normal, the vehicle repeatedly pulls to one
side under braking or brake noise is heard,
consult a workshop.
In order to utilise the full pedal travel,
particularly in the event of a brake circuit
fault, there must be no mats in the area of
the pedals - see page 128.
With the engine stopped, the brake servo
assistance is discontinued after the brake
pedal has been depressed once or twice.
The braking effect is not reduced, but
increased foot pressure will be necessary.
Take extra care when the vehicle is being
towed.
Check the brake lamps before starting out
on a journey. Shortly after the start of each
journey, the brake system should be tested
for its effectiveness at low speed and
without inconveniencing other road users,
especially if the brakes are wet, e.g. after
washing your vehicle.
Excessive braking when going downhill can
cause brakes to temporarily overheat. Shift
to a lower gear rather than continuously
applying brakes.
The brake fluid level should be checked
regularly - see page 196.
