Driving and operating153Operation of brake assist might
become apparent by a pulse in the
brake pedal and a greater resistance
when depressing the brake pedal.
Maintain steady pressure on the
brake pedal as long as full braking is
required. Maximum brake force is
automatically reduced when brake pedal is released.
Hill start assist The system helps prevent unintended
movement when driving away on
inclines.
When releasing the brake pedal after
stopping on an incline, brakes remain on for further 2 seconds. The brakes
release automatically as soon as the
vehicle begins to accelerate.Ride control systems
Electronic Stability Control and Traction Control system
Electronic Stability Control (ESC)
improves driving stability when
necessary, regardless of the type of
road surface or tyre grip.
As soon as the vehicle starts to
swerve (understeer / oversteer),
engine output is reduced and the wheels are braked individually.
ESC operates in combination with the Traction Control system (TC). It
prevents the driven wheels from
spinning.
The TC is a component of the ESC. Traction Control improves driving
stability when necessary, regardless
of the type of road surface or tyre grip,
by preventing the driven wheels from
spinning.
As soon as the driven wheels starts to spin, engine output is reduced and
the wheel spinning the most is brakedindividually. This considerably
improves the driving stability of the
vehicle on slippery road surfaces.
ESC and TC are operational after
each engine start as soon as the
control indicator b extinguishes.
When ESC and TC operate, b
flashes.
9 Warning
Do not let this special safety
feature tempt you into taking risks
when driving.
Adapt speed to the road
conditions.
Control indicator b 3 95.
172Driving and operating9Warning
Intelligent brake assist may
increase vehicle braking in
situations when it may not be
necessary. You could block the
flow of traffic. If this occurs, take
your foot off the brake pedal and
then apply the brakes as needed.
Forward collision alert 3 168.
Front pedestrian protection 3 173.
System limitations In some cases, the active emergencybraking system may provide an
automatic braking in situations that
seem to be unnecessary, for instance
in parking garages, due to traffic signs in a curve or due to vehicles in
another lane. This is normal
operation, the vehicle does not need service. Firmly apply the accelerator
pedal to override the automatic
braking if the situation and the
surroundings permit.
In the following cases, active
emergency braking performance is limited:
● driving on winding or hilly roads
● detecting all vehicles, especially vehicles with a trailer, tractors,
muddy vehicles, etc.
● detecting a vehicle when weather
limits visibility, such as in fog,
rain, or snow
● driving during nighttime
● sensor in the windscreen or radar
unit behind the front bumper
blocked by snow, ice, slush, mud, dirt, etc.
● windscreen damaged or affected
by foreign objects, e.g. stickers
Complete attention is always required
while driving, and you should be
ready to take action and apply the
brakes and / or steer the vehicle to
avoid crashes.We recommend to deactivate the
system in the vehicle personalisation
in the following cases:
● when towing a trailer or caravan
● when carrying long objects on roof bars or a roof rack
● when the vehicle is being towed with the engine running
● when a spare wheel is fitted that is smaller than the other wheels
● before using an automatic car wash with the engine running
● before placing the vehicle on a rolling road in a workshop
● if the windscreen has been damaged close to the camera
● if the front bumper has been damaged
● if the brake lamps are not working
Fault
In case the system requires a service, a message is displayed in the Driver
Information Centre.
188Driving and operatingAfter ignition is switched on, the lane
departure warning system is
activated. If the system is activated,
the LED in the button ½ is not
illuminated. To activate the system
when the system is deactivated,
press ½.
The system is only operable at
vehicle speeds above 37 mph and if
lane markings are available.
When the system recognises an
unintended lane departure, the
control indicator ) flashes yellow.
Simultaneously a chime sound is
activated.
Deactivation
To deactivate the system, press andhold ½. The LED in the button is
illuminated and ½ illuminates yellow in
the instrument cluster.
At speeds below 37 mph the system
is inoperable.
Fault
In the event of a fault, H appears
in the instrument panel, accompanied
by a display message and a warning
chime. Contact a dealer or a qualified
workshop to have the system
checked.
System limitations The system performance may notoperate properly when:
● Vehicle speed is below 37 mph.
● Windscreen is not clean or affected by foreign objects, e.g.
stickers.
● Driving on winding or hilly roads.
● During nighttime driving.
● Adverse environmental conditions like heavy rain, snow,
direct sunlight or shadows.
● The sensor in the windscreen is blocked by snow, ice, slush, mud,dirt, windscreen damage or
affected by foreign objects, e.g.
stickers.● The sun is shining directly into the camera lens.
● Close vehicles ahead.
● Driving on banked roads.
● Driving on road edges.
● Driving on roads with poor lane markings.
● Sudden lighting changes.
The system can not operate when no
lane marking is detected.
Lane keep assist
Lane keep assist helps to avoid
crashes due to unintentional lane
departures. The front camera
observes the lane markings between
which the vehicle is driving. If the
vehicle approaches a lane marking, the steering wheel is gently turned to
position the vehicle back into the lane. The driver will then notice a turning
movement of the steering wheel. Turn steering wheel in same direction, if
system steers not sufficient. Turn steering wheel gently into opposite
direction, if lane change is intended.
190Driving and operatingthe correction. A warning message inthe Driver Information Centre
accompanied by a warning chime
alerts the driver when immediate
driver´s action is required.
Deactivation To deactivate the system, press andhold Ó. Deactivation of the system is
confirmed by the illuminated LED in
the button. In the Driver Information
Centre solid grey lines are displayed.
Fault
In the event of a fault, a and H
appear in the instrument panel, accompanied by a display message
and a warning chime. Contact a
dealer or a qualified workshop to have the system checked.
System limitations The system performance may be
affected by:
● windscreen not clean or affected by foreign objects, e.g. stickers
● close vehicles ahead
● banked roads● winding or hilly roads
● road edges
● sudden lighting changes
● adverse environmental conditions, e.g. heavy rain or
snow
● vehicle modifications, e.g. tyres
Switch off the system if the system is
disturbed by tar marks, shadows,
road cracks, temporary or
construction lane markings, or other
road imperfections.9 Warning
Always keep your attention on the
road and maintain proper vehicle
position within the lane, otherwise
vehicle damage, injury or death
could occur.
Lane keep assist does not
continuously steer the vehicle.
The system may not keep the
vehicle in the lane or give an alert,
even if a lane marking is detected.
The steering of the lane keep
assist may not be sufficient to
avoid a lane departure.
The system may not detect hands-
off driving due to external
influences like road condition and
surface and weather. The driver has full responsibility to control the vehicle and is always required to
keep the hands on the steering
wheel while driving.
Using the system while towing a
trailer or on slippery roads could
cause loss of control of the vehicle
and a crash. Switch the system off.
Driver alert
The driver alert system monitores the driving time and the vigilance of the
driver. Monitoring the vigilance of the
driver is based on the trajectory
variations of the vehicle compared to
the lane markings.
The system includes a driving time
alert combined with driver drowsiness detection.
