134 Driving and operating
Dynamic braking when vehicle is
moving
When the vehicle is moving and the
switch m is kept pulled, the electrical
parking brake system will decelerate
the vehicle, but will not apply
statically.
As soon as the switch m is released,
dynamic braking will be stopped.
Fault
Failure mode of electrical parking
brake is indicated by control indicator
j and by a code number or a vehicle
message which is displayed in the
Driver Information Center. Vehicle
messages 3 98.
Apply electrical parking brake: pull
and hold the switch m for more than
5 seconds. If control indicator m
illuminates, electrical parking brake is
applied.
Release electrical parking brake:
push and hold the switch m for more
than 2 seconds. If control indicator
m goes out, electrical parking brake
is released.
Control indicator m flashes: electrical
parking brake is not fully applied or
released. When continuously
flashing, release electrical parking
brake and retry applying.
Brake assist
If the brake pedal is depressed
quickly and forcefully, maximum
brake force is automatically applied
(full braking).
Maintain steady pressure on the
brake pedal for as long as full braking
is required. Maximum brake force is
automatically reduced when the
brake pedal is released.
Hill start assist
The system helps prevent unintended
movement when driving away on
inclines.
When releasing the foot brake after
stopping on an incline, the brakes
remain on for a further two seconds.
The brakes release automatically as
soon as the vehicle begins to
accelerate.
Ride control systems
Traction Control system
The Traction Control system (TC) is
a component of the Electronic
Stability Control system.
TC improves driving stability when
necessary, regardless of the type of
road surface or tyre grip, by
preventing the drive wheels from
spinning.
As soon as the drive wheels starts to
spin, engine output is reduced and
the wheel spinning the most is braked
individually. This considerably
improves the driving stability of the
vehicle on slippery road surfaces.
TC is operational as soon as the
control indicator b extinguishes.
When TC is active b flashes.
