Driving
●
Bef
ore driving down a long, steep gradient,
it is advisable to reduce speed and select a
lower gear. This makes use of engine braking
and relieves the brakes. If you still have to
use the brakes, it is better to brake firmly at
intervals than to apply the brakes continu-
ously. Note
● If the br
ake servo is out of action, for exam-
ple when the car is being towed, you will
have to press the brake pedal considerably
harder than normal to make up for the lack of
servo assistance.
● If you wish to equip the vehicle with acces-
sories
such as a front spoiler or wheel covers,
it is important that the flow of air to the front
wheels is not obstructed, otherwise the
brakes can overheat. Front assist system
Electronic stability control (ESC)
The E
SC
helps to improve safety. It reduces
the tendency to skid and improves the stabil-
ity and roadholding of the vehicle. The ESC
detects critical handling situations, such as
vehicle understeer or oversteer, or wheelspin
on the driving wheels. It stabilises the vehi-
cle by braking individual wheels or by reduc-
ing the engine torque. The warning lamp will flash on the instrument panel when the ESC
is
intervening .
The ESC includes the anti-lock brake system
(ABS), the front assist system (HBA), the trac-
tion control system (ASR), electronic differen-
tial lock (EDS), electronic torque control
(XDS) and tractor-trailer sway mitigation*.
ESC also helps stabilise the vehicle by chang-
ing the torque.
Anti-lock brake system (ABS)
ABS prevents the wheels from locking up un-
der braking until the vehicle has reached a
virtual standstill. You can continue to steer
the vehicle even when the brakes are on full.
Keep your foot on the brake pedal and do not
pump the brakes. You will feel the brake ped-
al pulsate while the ABS is working.
Front assist system (HBA)
The brake assist system can reduce the re-
quired braking distance. The braking force is
automatically boosted if you press the brake
pedal quickly in an emergency. You must
keep pressing the brake pedal until the dan-
ger has passed.
Traction control system (ASR)
In the event of wheelspin, the traction control
system reduces the engine torque to match
the amount of grip available. This helps the car to start moving, accelerate or climb a gra-
dient.
El
ectronic differential lock (EDL)
When the EDL detects wheelspin, it brakes
the spinning wheel and directs the power to
the other driven wheel. This function is active
up to approximately 100 km/h (62 mph).
To prevent the disc brake of the braked wheel
from overheating, the EDL cuts out automati-
cally if subjected to excessive loads. The ve-
hicle can still be driven. The EDL will switch
on again automatically when the brake has
cooled down.
Tractor-trailer sway mitigation*
If the vehicle is pulling a trailer, it will control
the following: Tractor-trailers tend to sway.
When the swaying of the trailer is felt by the
vehicle and detected by the ESC, it will auto-
matically brake the towing vehicle within the
limits of the system and mitigate the sway.
Tractor-trailer sway mitigation is not available
in all countries.
Electronic torque management (XDS)
When taking a curve, the driveshaft differen-
tial mechanism allows the outer wheel to turn
at a higher speed than the inner wheel. In
this way, the wheel that is turning faster (out-
er wheel) receives less drive torque than the
inner wheel. This may mean that in certain »

Some warning and control lamps will light up
briefly when the ignition i
s switched on to
check certain functions. They will switch off
after a few seconds.
If there are no indications from the control
lamp in the external rear view mirror, this
means that the blind spot detector has not
detected any other vehicles in the area ››› .
If the dip
ped beam is on, then the control
lamps in the external rear view mirrors will be
dimmed (night mode). WARNING
If the warning lamps and the corresponding
me s
sages are ignored when they light up, the
vehicle may stall in traffic and cause acci-
dents and severe injuries.
● Never ignore the warning lamps or messag-
es.
● C
arry out the necessary operations. CAUTION
Failure to heed the control lamps and corre-
s pondin
g text messages when they light up
may result in damage to the vehicle. Blind spot detector (BSD)

In the exterior mirrors: indication of

pot detector. Fig. 193
Rear view of the vehicle: radar sen-

ones. The blind spot detector uses radar sensors to
monit
or the ar
eas behind the vehicle
››› Fig. 193. The system does this by measur-
ing the vehicle's distance from other vehicles
and its speed differential. The blind spot de-
tector will not work at speeds of less than ap-
prox. 15 km/h (9 mph). The system uses opti-
cal signals in the external rear view mirrors to
notify the driver.
Indication in the external rear view mirrors
The control lamp (expanded view) provides
an indication in the corresponding external
mirror ››› Fig. 192 regarding the traffic situa-
tion behind the vehicle, if it is deemed to be
critical. The control lamp of the left-hand ex-
ternal mirror indicates the traffic situation to
the left of the vehicle, and the control lamp of
the right-hand external mirror indicates the
traffic situation to the right of the vehicle. »

cation w
ill be displayed.
The faster the vehicle approaches, the sooner
an indication will be displayed in the external
mirror, because the blind spot detector takes
into account the speed differential with other
vehicles. Thus even though the distance from
the other vehicle is identical, the indication
will appear sooner in some cases and later in
others. Physical limitations inherent to the system
In some sit
uations the blind spot detector
may not interpret the traffic situation correct-
ly. E.g. in the following situations:
● on tight bends;
● in the case of lanes with different widths;
● at the top of slopes;
● in adverse weather conditions; »
