Driver assistance systems
The
warning lamp on the general instru-
ment
panel starts flashing when the system
is working.
The stability (ESC) system includes the fol-
lowing systems:
●
Anti-lock brake system (ABS),
●
Traction control system (TCS),
●
Electronic differential lock (EDL),
●
Hydraulic brake assist system (HBA),
●
Hill hold control (HHC).
The ESC system cannot be switched on. The
››› Fig. 95
button can only be used to
sw
it
ch off the TCS system. The warning
lamp lights up on the general instrument
panel if the TCS system is switched off.
The ASR should be switched on at all times.
Only under certain circumstances should the
system be switched off, e.g.
●
driving with chains,
●
driving in deep snow or on very soft surfa-
ces,
●
During the “swinging movement” required
to remove a stuck vehicle
Switch the ASR back on as soon as possible.
Brake assist system (HBA)*
The HBA system is activated when you press
down on the brake pedal suddenly. It increa-
ses braking power, helping to reduce braking
distances. To reduce braking distance as
much as possible, keep the brake pedal
pressed down firmly until the vehicle comes
to a standstill.
With the help of this system, the ABS is acti-
vated more quickly and more efficiently.
The brake assist function is deactivated auto-
matically when the brake pedal is released.
Hill hold control (HHC)*
The HHC system makes it easier to start the
vehicle on hills. The system maintains the
brake pressure created by pressing down on
the brake pedal for 2 seconds after it has
been released. Your foot can be removed
from the brake pedal and you can use the ac-
celerator pedal and move away on a hill with-
out having to use the handbrake. The brake
pressure drops as the accelerator pedal is
pressed. If the vehicle cannot be started, it
will start to move backwards after 2 seconds.
The HHC is activated on gradients of over
5%, if the driver door is closed. It only works
for starting on hills, moving both forward and
in reverse. It is not activated during start-up
down hill.
Anti-lock system (ABS)
The ABS system prevents the wheels locking
during braking. This helps the driver keep
control of the vehicle.
The driver is made aware of ABS assistance
by the pulsating of the brake pedal and a
characteristic noise.
Keep the brake pedal pressed down while the
ABS is working. The ABS will switch off when
the brake pedal is released. Never brake in-
termittently while the ABS is working!
Traction control system (ASR)
If the wheels start to slip, the TCS adapts the
engine speed to the driving conditions. Par-
ticularly in unfavourable conditions, the TCS
helps starting, accelerating and hill starts.
