Launch Control
Launch Control enables an optimum accelera-
tion when starting off on a road surface with 
good traction.
Do not use Launch Control too often; oth-
erwise, the powerful stresses on the vehi-
cle will lead to premature component wear.<
Launch Control is available when the engine is 
at operating temperature, i.e. after driving con-
tinuously for approx. 6.2 miles/10 km.
1.With the engine running, step on the brake 
with your left foot.
2.Activate Dynamic Traction Control (DTC), 
refer to page90.
3.Activate Driving dynamics control, refer to 
page62.
4.With the vehicle stationary, activate the 
manual mode and select 1
stgear.
5.With your right foot, push the accelerator 
pedal past the resistance point. The engine 
speed for pulling away is adjusted. A flag 
symbol appears in the instrument cluster.
6.When you release the brake pedal, the vehi-
cle accelerates. Keep the accelerator pedal 
floored.
7.The upshifting occurs automatically as long 
as you keep the accelerator pedal pressed 
past the resistance point.
Launch Control will be ready for use again after 
you drive a certain distance.
Launch Control is not available for use during 
the break-in phase, refer to page126.
To maintain driving stability, keep DSC 
activated whenever possible.<

Cleaning windshield and headlamps*
Pull the lever, arrow 4.
Washer fluid is sprayed onto the windshield and 
the wipers are operated for a short time.
When the vehicle lighting system is switched 
on, the headlamps are cleaned at regular and 
appropriate intervals.
Do not use the washers if there is any 
danger that the fluid will freeze on the 
windshield. If you do, your vision could be 
obscured. Antifreeze should therefore be 
added to the fluid, refer to Washer fluid. 
Do not use the washers when the washer fluid 
reservoir is empty; otherwise, you will damage 
the washer pump.<
Windshield washer nozzles
The windshield washer nozzles are heated 
automatically
* while the engine is running or 
the ignition is switched on.
Washer fluid
Washer fluid antifreeze is flammable. 
Therefore, keep it away from ignition 
sources and only store it in the closed original 
container that is kept out of reach of children; 
otherwise, there is a risk of personal injury. 
Comply with the instructions on the con-
tainer.<
Washer fluid filler neck
Only refill washer fluid when the engine is 
cool to avoid contact with hot engine 
parts. Otherwise, fluid spills constitute a fire 
hazard and a risk to personal safety.
Fill with water and, if required, with a washer 
antifreeze, according to manufacturer's recom-
mendations.
Mix the water and antifreeze before filling 
the washer fluid reservoir to make sure 
the correct concentration is maintained.<
Capacity
Approx. 6.3 US quarts/6 liters.
Cruise control*
The concept
Cruise control is available for use at speeds of 
approx. 20 mph or 30 km/h. The car then stores 
and maintains the speed that you specify using 
the lever on the steering column. In order to 
maintain the specified speed, the system 
brakes the vehicle when the engine braking 
effect is insufficient on downhill gradients.
Do not use cruise control when driving at 
constant speed is prevented by adverse 
conditions, e.g. winding roads, dense traffic or 
poor road conditions due to, e.g., snow, rain, ice 
or loose surfaces. Otherwise, you could lose 
control of the vehicle and cause an accident as 
aresult.<
Manual transmission
You can shift gears while cruise control is acti-
vated. The system is deactivated when you 
drive at very low engine speeds for an extended 
period.

Displays the estimated cruising range available 
with the remaining fuel. The range is calculated 
on the basis of the way the car has been driven 
over the last 18 miles/30 km and the amount of 
fuel currently in the tank.
Refuel as soon as possible once your 
cruising range falls below 30 miles/
50 km; otherwise, engine functions are not 
ensured and damage can occur.<
Average speed
Periods with the vehicle parked and the engine 
switched off are not included in the calculations 
of average speed.
With the trip computer, refer to page78, you 
can have the average speed for another trip dis-
played.
To reset average speed: press the button in the 
turn indicator lever for approx. 2 seconds.
Average fuel consumption
The average fuel consumption is calculated for 
the time during which the engine is running.
You can have the average consumption for 
another trip displayed, refer to Displays on the 
Control Display below.
To reset average fuel consumption: press the 
button in the turn indicator lever for approx. 
2seconds.

Park Distance Control PDC*
The concept
The PDC assists you with maneuvering in tight 
parking spaces. Acoustic signals and a visual 
indicator
 warn you of the presence of an object 
in front of
* or behind your vehicle. To measure 
the distance, there are four ultrasonic sensors 
in either bumper.
These sensors have a range of approx. 6.5 ft/
2 m. However, an acoustic warning does not 
sound until the sensors at the front
* and at the 
two rear corners are approx. 24 in/60 cm away 
from the object and the middle rear sensors are 
approx. 5 ft/1,50 m away from it.
PDC is a parking aid that can indicate 
objects when they are approached 
slowly, as is usually the case when parking. 
Avoid approaching an object at high speed; oth-
erwise, physical circumstances may lead to the 
system warning being issued too late.<
Switching on automatically
With the engine running or the ignition switched 
on, the system is activated after approx. one 
second when you shift into reverse or move the 
automatic transmission selector lever to 
position R. Wait this short period before driving.
Switching off automatically
After approx. 55 yd/50 m of driving or above 
approx. 20 mph/approx. 30 km/h, the system 
switches off and the LED goes out.
Switching on manually*
Press the button; the LED lights up.
Switching off manually*
Press the button again; the LED goes out.
Signal tones
When nearing an object, its position is indicated 
correspondingly by an interval tone. For exam-
ple, if an object is detected behind the vehicle, 
the signal tone sounds from the rear. As the dis-
tance between vehicle and object decreases, 
the intervals between the tones become 
shorter. If the distance to the nearest object 
falls to below roughly 1 ft/30 cm, then a contin-
uous tone sounds.
An interval tone is interrupted after approx. 
3seconds
>If you remain in front of an object that has 
been detected by only one of the corner 
sensors
>If you are driving parallel to a wall.

3Automatic headlamp control
*, daytime run-
ning lights, welcome lamps, high-beam 
assistant
* and adaptive light control*
When you open the driver's door with the igni-
tion switched off, the exterior lighting is auto-
matically switched off if the light switch is in 
position 0, 2 or 3.
Switch on the parking lamps if necessary, 
switch position 1.
Parking lamps
In switch position1, the front, rear and side 
vehicle lighting is switched on. You can use the 
parking lamps for parking.
The parking lamps will discharge the bat-
tery. Therefore, do not leave them on for 
unduly long periods of time; otherwise, the bat-
tery might not have enough power to start the 
engine. It is preferable to switch on the left-
hand or right-hand roadside parking lamps, 
refer to page103.<
Low beams
The low beams light up when the light switch is 
in position 2 and the ignition is on.
Automatic headlamp control*
When the switch is in position3, the low beams 
are switched on and off automatically depend-
ing on ambient light conditions, e.g. in a tunnel, 
in twilight, or if there is precipitation. The adap-
tive light control
* is active. The LED next to the 
symbol is illuminated when the low beams are 
on. You can also activate the daytime running 
lights, refer to page102. In the situations 
described above, the lamps then automatically 
switch from daytime running lights to low 
beams.
The headlamps may also come on when the 
sun is sitting low on a blue sky.
The low beams remain switched on 
regardless of the ambient lighting condi-
tions when you switch on the fog lamps.<
The automatic headlamp control cannot 
serve as a substitute for your personal 
judgment in determining when the lamps 
should be switched on in response to ambient 
lighting conditions. For example, the system 
cannot detect fog or hazy weather. To avoid 
safety risks, you should always switch on the 
low-beam headlamps manually under these 
conditions.<
Welcome lamps
If you leave the light switch in position 2 or 3 
when you park the car, the parking lamps and 
the interior lamps light up briefly when you 
unlock the vehicle.

Adaptive light control*
The concept
Adaptive light control is a variable headlamp 
control system that enables better illumination 
of the road surface. Depending on the steering 
angle and other parameters, the light from the 
headlamp follows the course of the road.
In tight curves at speeds up to 40 mph/70 km/h, 
e.g. on mountainous roads or when turning, an 
additional, corner-illuminating lamp is switched 
on that lights up the inside area of the curve.
Activating Adaptive Light Control
With the ignition switched on, turn the light 
switch to position 3, refer to page101. 
The corner-illuminating lamp is switched on 
automatically, depending on the steering wheel 
angle or turn signal indicator.
Standstill function
*: to avoid blinding oncoming 
traffic, the adaptive light control directs light 
towards the front passenger side when the 
vehicle is at a standstill.
When you are reversing, only the corner-illumi-
nating lamps are switched on and active on 
both sides.
