Even though the brake assistance systems,
ABS, BAS, EDL, ASR and ESC, provide more
security, do not take unnecessary risks
while driving.
Brake assistance systems can not over-
●
come the laws of physics. Even with ESC
and other systems, slippery and wet roads
will always be dangerous.
Driving to quickly on wet ground can re-
●
sult in the wheels losing contact with the
ground in an effect known as "aquaplan-
ing". Without adherence, it is impossible to
brake, steer or control the vehicle.
Brake assistance systems cannot avoid
●
accidents if, for example, the driver does
not respect safety distances or drives to
quickly in difficult conditions.
Even though brake assistance systems
●
are extremely effective and help control
the vehicle in difficult situations, remember
that the vehicle stability depends on tyre
grip.
When accelerating on a slippery surface,
●
for example on ice or snow, press the ac-
celerator carefully. The wheels can still slip
even with brake assistance systems result-
ing in loss of vehicle control.
WARNING
The effectiveness of ESC can be consider-
ably reduced if other components and sys-
tems affecting driving dynamics are not
maintained or are not functioning correct-

ly. This includes, among others, brakes,
tyres and other systems already men-
tioned.
Remember that changing and fitting oth-
●
er components to the vehicle can affect
operation of the ABS, BAS, ASL EDL and
ESC.
Changes to the vehicle suspension or us-
●
ing unapproved wheel/tyre combinations
can affect operation of the ABS, BAS, ASL
EDL and ESC, as well as their effectiveness.
Likewise, the effectiveness of ESC de-

pends on the use of suitable tyres

page 338.
Note
To ensure that the ESC and ASR work
●
properly, all four wheels must be fitted with
identical tyres. Any differences in the roll-
ing radius of the tyres can cause the sys-
tem to reduce engine power when this is
not desired.
If a malfunction should occur in the ABS,
●
the ESC, EDL and ASR will also be out of ac-
tion.
Noises may be heard while any of the
●
above systems are operating.
Switching ASR on and off

button used to switch ASR on and off (vehicles
with ESC)
The electronic stability control ESC consists
of ABS, EDL and ASR and only works when
the engine is running.
The ASR can be switched off while the engine
is running by pressing the

switched off when the required traction is not
obtained:
When driving through deep snow or on

loose ground (gravel, etc.).
When "freeing" a trapped vehicle.
