Starting the engine
The engine starts automatically under the fol‐
lowing conditions:
▷M double-clutch transmission:
By releasing the brake pedal.▷Manual transmission:
The clutch pedal is pressed.
After the engine starts, accelerate as usual.
Safety mode
After the engine switches off automatically, it
will not start again automatically if any one of
the following conditions are met.
▷The driver's safety belt is unbuckled and
the driver's door is open.▷The hood was unlocked.
Some indicator lights light up for a varied
length of time.
The engine can only be started via the Start/
Stop button.
Functional limitations
Even if driving off was not intended, the deacti‐
vated engine starts up automatically in the fol‐
lowing situations:
▷Excessive warming of the car's interior
when the cooling function is switched on.▷The steering wheel is turned.▷Double-clutch transmission: Change from
selector lever position D to N, R or D/S.▷M double-clutch transmission: Accelerat‐
ing while simultaneously applying the
brake.▷The vehicle begins rolling.▷Fogging of the windows when the auto‐
matic climate control is switched on.▷Vehicle battery is heavily discharged.▷Excessive cooling of the car's interior when
the heating is switched on.▷Low brake vacuum pressure; this can oc‐
cur, e.g., if the brake pedal is depressed a
number of times in succession.
Preventing an automatic engine stop with aM double-clutch transmission
The concept To make it possible to drive off very quickly,
such as at an intersection, the automatic en‐
gine stop can be actively prevented.
Preventing an engine stop using the
brake pedal
The engine stop can be actively prevented
within one second after the vehicle comes to a
standstill.
▷Immediately after the vehicle comes to a
standstill, briefly press the brake pedal
forcefully.▷Then press the brake pedal with normal
braking force.Seite 67DrivingControls67

The lever automatically returns to its initial po‐
sition when released.▷Normal wiper speed: push up once.
The wipers switch to intermittent operation
when the vehicle is stationary.▷Fast wiper speed: press up twice or press
once beyond the resistance point.
Wipers change to normal speed when ve‐
hicle comes to standstill.
Switch off and brief wipe
Push wiper lever down.
The lever automatically returns to its initial po‐
sition when released.
▷Single wipe: press down once.▷To switch off normal wipe: press down
once.▷To switch off fast wipe: press down twice.
Interval mode or rain sensor
The concept The rain sensor automatically controls the time
between wipes depending on the intensity of the rainfall. The sensor is located on the wind‐
shield, directly behind the interior rearview mir‐
ror.
Activating/deactivating
Press button on the wiper lever.
Wiping is started. If the vehicle is equipped
with a rain sensor: LED in wiper lever lights up.
When wipers are frozen to windshield, wiper
operation is deactivated.
During trip interruption with the rain sensor
switched on: if the trip is resumed within ap‐
prox. 15 minutes, the rain sensor is automati‐
cally activated again.
Deactivate the rain sensor in car washes
Deactivate the rain sensor when passing
through an automatic car wash; otherwise, un‐
intentional wiping can cause damages.◀
Setting the frequency or sensitivity of
the rain sensor
Turn the thumbwheel.

Speed limit detection can also be displayed in
the Head-up Display.
System limits The system may not be fully functional and
may provide incorrect information in the fol‐
lowing situations:▷In heavy fog, rain or snowfall.▷When signs are concealed by objects.▷When driving very close to the vehicle in
front of you.▷When driving toward bright lights.▷When the windshield behind the interior
rearview mirror is fogged over, dirty or cov‐
ered by a sticker, etc.▷In the event of incorrect detection by the
camera.▷If the speed limits stored in the navigation
system are incorrect.▷In areas not covered by the navigation sys‐
tem.▷When roads differ from the navigation,
such as due to changes in road routing.▷When passing buses or trucks with a
speed sticker.▷If the traffic signs are non-conforming.▷During calibration of the camera immedi‐
ately after vehicle shipment.
Selection lists in the
instrument cluster
The concept Depending on your vehicle's optional features,
the following can be displayed or operated us‐
ing the buttons and the thumbwheel on the
steering wheel as well as the displays in the in‐
strument cluster and the Head-up Display:
▷Current audio source.▷Redial phone feature.▷Turn on voice activation system.

Depending on your vehicle's optional features,
the list in the instrument cluster can differ from
the illustration shown.

Parking lights
Position of switch
: the vehicle's lights
light up on all sides, e.g., for parking.
Do not use the parking lights for extended pe‐
riods; otherwise, they might drain the battery
and it would then be impossible to start the en‐
gine.
When parking, it is preferable to switch on the
one-sided roadside parking lights, refer to
page 97.
Low beams Position of switch

ActivatingPosition of switch
with the ignition
switched on.
To avoid blinding oncoming traffic, the Adap‐
tive Light Control does not swivel to the driv‐
er's side when the vehicle is at a standstill.
The turning lights are automatically switched
on depending on the steering angle or the use
of turn signals.
When driving in reverse, the turning lights may
be automatically switched on regardless of the
steering angle.
Self-leveling headlights The self-leveling headlights compensate for
acceleration and braking operations in order
not to blind the oncoming traffic and to achieve
optimum illumination of the roadway.
Malfunction A Check Control message is displayed.
Adaptive Light Control is malfunctioning or has
failed. Have the system checked as soon as
possible.
High-beam Assistant
The concept When the low beams are activated, this system
automatically switches the high beams on and
off or suppresses the light in the areas that
blind oncoming traffic. The procedure is con‐
trolled by a camera on the front of the interior
rearview mirror. The assistant ensures that the
high beams are activated whenever the traffic
situation allows. The driver can intervene at
any time and switch the high beams non and
off as usual.
Note
Personal responsibility
The High-beam Assistant cannot serve
as a substitute for the driver's personal judg‐
ment of when to use the high beams. There‐
fore, manually reel off the high beams in situa‐
tions where required to avoid a safety risk.◀
Activating1.Depending on the equipment, turn the light
switch into position
or .
2.Press button on the turn signal lever, ar‐
row.
The indicator lamp in the instrument
cluster lights up.
When the low beams are on, the lights are au‐
tomatically brightened or dimmed.
The system responds to light from oncoming
traffic and traffic driving ahead of you, and to
adequate illumination, e.g., in towns and cities.
The blue indicator lamp in the instru‐
ment cluster lights up when the system
switches on the high beams. Depend‐
ing on the version of the system in the vehicle, the high beams may not switch off for oncom‐
ing vehicles, but may only be dimmed in the
areas that blind oncoming traffic. In this case,
the blue indicator light will stay on.

System limits
The system is not fully functional in situations such as the following, and driver intervention
may be necessary:
▷In very unfavorable weather conditions,
such as fog or heavy precipitation.▷When detecting poorly-lit road users such
as pedestrians, cyclists, horseback riders
and wagons; when driving close to train or
ship traffic; and at animal crossings.▷In tight curves, on hilltops or in depres‐
sions, in cross traffic or half-obscured on‐
coming traffic on freeways.▷In poorly-lit towns and cities and in the
presence of highly reflective signs.▷At low speeds.▷When the windshield behind the interior
rearview mirror is fogged over, dirty or cov‐
ered with stickers, etc.Instrument lighting
