WARNING
You should switch on the ESC Sport mode on-
ly if the tr
affic conditions and your driving
ability allow you to do so safely: risk of skid-
ding!
●
With ESC in Sport mode, the stabilising
function will be limited to allow for a sportier
drive. The driving wheels could spin and the
vehicle could skid.
Note
If the ASR is disconnected or the ESC’s Sport
mode is sel
ected, cruise control* will be
switched off.
Electronic Stability Control (ESC)*
This Electronic Stability System reduces the
ri
sk
of
skidding and improves the vehicle's
stability and ability to hold the road.
The Electronic Stability Control (ESC) contains
the electronic differential lock (EDL) and the
traction control system (ASR). The ESC works
together with the ABS. Both control lamps
will light up if the ESC or ABS systems are
faulty.
The ESC system is started automatically
when the engine is started.
The ESC system is always active and cannot
be switched off. With the Easy Connect sys-
tem it is only possible to deactivate the ASR
or else select Sport mode.
The ASR can be deactivated when wheel spin
is desirable ››› page 172.
For example:
●
When driving with snow chains.
●
When driving in deep snow or on loose sur-
faces.
●
When the vehicle is stuck, to rock it back-
wards and forwards.
Press the button to switch the ASR back on
when you no longer need wheel spin.
Electronic Stability Control (ESC)*
The ESC reduces the risk of skidding by brak-
ing the wheels individually.
The system uses the steering wheel angle
and road speed to calculate the changes of
direction desired by the driver, and constant-
ly compares them with the actual behaviour
of the vehicle. When irregularities occur, for
example, if the vehicle begins to skid, the
ESC brakes the appropriate wheel automati-
cally.
The forces acting on the braked wheel bring
the vehicle back to a stable condition. If the
vehicle tends to oversteer (the rear end
slides out), the system will act on the front
wheel on the outside of the turn.
WARNING
●
Do not for
get that the electronic stability
control ESC cannot defy the laws of physics.
This should be kept in mind, particularly on
slippery and wet roads and when towing a
trailer.
●
Always adapt your driving style to suit the
condition of the roads and the traffic situa-
tion. The greater safety provided by the ESC
should not encourage you to run any risks.
CAUTION
●
To ens
ure that the ESC works correctly, all
four wheels must be fitted with the same
tyres. Any differences in the rolling radius of
the tyres can cause the system to reduce en-
gine power when this is not desired.
●
Any modifications made to the vehicle (for
example, to the engine, brake system, run-
ning gear or to the combination of wheels
and tyres) may affect the operation of the
ABS, EDL, ESC and ASR.
Electronic differential lock (EDS)*
EDL helps the vehicle to start moving, accel-
er
at
e and c
limb a gradient in slippery condi-
tions where this may otherwise be difficult or
even impossible.
