Operation
The control lamp h
a
s
the following func-
tions:
●
It flashes whilst driving when the ASR/ESC
is activated.
●
It will light up if there is a fault in the ESC.
●
As the ESC operates in conjunction with the
ABS, the ESC light will also come on if a fault
should occur in the ABS.
If the ESC control lamp lights up and stays
on after the engine is started, this may mean
that the control system has temporarily
switched off the ESC. In this case the ESC can
be reactivated by switching the ignition off
and then on again. If the control lamp goes
out, this means the system is fully functional.
The lamp provides information about the
disconnection status of the system:
●
It stays lit when the ASR is disconnected or
if you select ESC Sport mode, only by means
of Easy Connect.
WARNING
●
Do not for
get that the electronic stability
control ESC cannot defy the laws of physics.
Bear this 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.
Traction control system (ASR)
The traction control system prevents the driv-
en wheel
s
fr
om spinning when the vehicle is
accelerating.
Description and operation of the traction
control system during acceleration (ASR)
The ASR system intervenes by reducing en-
gine power and preventing the driven wheels
from slipping during acceleration.
TCS helps the car to start moving, accelerate
and climb a gradient in slippery conditions
where this may otherwise be difficult or even
impossible.
The ASR automatically switches on when the
engine is started. If necessary, it could be
switched on or off using the Easy Connect
system*.
When the ASR is off, the warning lamp lights
up . The ASR should normally be left on.
Only in exceptional cases can it be discon-
nected, i.e. when you want the wheels to
slide; this done through the Easy Connect
system, by means of the
button and the
f
u
nction b
utton SETTINGS> ESC system,
for example:
●
With compact temporary spare wheel.
●
When using the snow chains.
●
When driving in deep snow or on soft ter-
rain.
●
When the vehicle is bogged-down, to free it
by “rocking it”.
The ASR should be switched on again as
soon as possible.
Control lamp
There are three control lamps for the traction
control system: (for vehicles equipped
with M-ABS), (for vehicles equipped with
ESC) and . Both control lamps light up to-
gether when the ignition is switched on and
should turn off after approximately 2 sec-
onds, which is the time taken for the function
check.
The or lamp has the following function:
●
It flashes when the ASR is working if the ve-
hicle i
s moving.
