Driving
Low brake fluid level
M alf
u
nctions can occur in the brake system if
the brake fluid level is too low. The brake flu-
id level is monitored electronically.
Brake servo
The brake servo increases the pressure you
apply to the brake pedal. It works only when
the engine is running. WARNING
● App ly
the brakes heavily to clean the brake
system only in a suitable traffic situation. Do
not put other road users in danger: there is
risk of causing an accident.
● Ensure the vehicle does not move while in
neutral, when the en
gine is stopped. Failure
to follow this instruction could result in an
accident.
● If the brake fluid loses its viscosity and is
subj
ected to heavy use, vapour bubbles can
form in the brake system. This reduces the ef-
ficiency of the brakes. CAUTION
● Never l et
the brakes “drag” by leaving your
foot on the pedal when it is not necessary to
brake. This overheats the brakes, resulting in
longer stopping distances and greater wear.
● Before 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 br
ak
es, it is better to brake firmly at
intervals than to apply the brakes continu-
ously. Note
● If the br ak
e 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 s
uch 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. Hydraulic Brake Assist (HBA)
Electronic stability control (ESC)
The E
SC
help
s 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 hydraulic brake assist (HBA), the traction control system (ASR), electronic dif-
ferenti
al 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.
Hydraulic Brake Assist (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.
Electronic differential lock (EDL)
When the EDL detects wheelspin, it brakes
the spinning wheel and directs the power to »

Operation
Flashes
The blind spot detector has detected a vehicle in the
blind spot and the turn signal has been turned on in the
direction of the detected vehicle
›››
.
For vehicles that are also equipped with Lane Assist
››› page 230, a warning to switch lanes will also appear
even though the turn signal has not been engaged
(blind spot detector “Plus”). 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 be
am 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
mes s
ages 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.
● Carr
y out the necessary operations. CAUTION
Failure to heed the control lamps and corre-
spondin g t
ext messages when they light up
may result in damage to the vehicle. Blind spot detector (BSD)

In the exterior mirrors: indication of

Rear view of the vehicle: radar sen-
sor z one
s. The blind spot detector uses radar sensors to
monit
or the ar
e
as behind the vehicle
››› Fig. 208. 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. 207 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.

(arrow) or ››› Fig. 210 (arrow):
● When being overtaken by another vehicle

● When overtaking another vehicle
›››
Fig. 210 with a speed differential of ap-
prox. 10 km/h (6 mph). If the vehicle is pass- ing at a considerably higher speed, no indi-
cation wi
ll 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 situation
s 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;
