Applying
The lever locks in position automatically.
Releasing
Pull slightly upwards, press the button and 
lower the lever.
In exceptional cases, if the parking brake 
has to be used to slow or stop the car, do 
not pull the lever up too hard. In doing so, con-
tinuously press the button of the parking brake 
lever. 
Otherwise, excessive force on the parking 
brake can lock up the rear wheels and cause the 
rear of the car to swerve.<
To prevent corrosion and one-sided brak-
ing action, occasionally apply the parking 
brake lightly when the vehicle is slowly coming 
to a stop if the traffic conditions are suitable.
The brake lamps do not light up when the park-
ing brake is applied.<
Manual transmission
When shifting into 5th or 6th gear, press 
the gearshift lever to the right. Otherwise 
the engine could be damaged if you inadvert-
ently shift into 3rd or 4th gear.<
Reverse gear
Select this only when the vehicle is stationary. 
When the gearshift lever is pressed to the left, a 
slight resistance has to be overcome.
Automatic transmission with 
Steptronic*
In addition to fully automatic operation, you can 
also manually shift with the Steptronic, refer to 
page62.
Vehicle parking
To prevent the vehicle from rolling, 
always select position P and apply the 
parking brake before leaving the vehicle with 
the engine running.<
Disengaging the remote control
In order to remove the remote control from the 
ignition lock, you must first move the selector

Upshifts and downshifts are executed only 
when they will result in a plausible combination 
of engine and vehicle speed; thus, for example, 
a downshift that would cause the engine to 
overrev will not be executed by the system. The 
gear selected is briefly displayed in the instru-
ment cluster, followed by the gear actually in 
use.
Shifting gears via shift paddles* on the 
steering wheel
The shift paddles allow you to shift gears 
quickly since both hands can remain on the 
steering wheel.
>When you use the shift paddles on the 
steering wheel to shift gears in automatic 
mode, the transmission switches to manual 
mode.
>If you do not accelerate or shift gears using 
the shift paddles for a certain amount of 
time, the transmission switches back to 
automatic mode.
If the selector lever is in the M/S gear 
plane, manual mode remains active.<
>To shift up: pull one of the shift paddles.
>To shift down: press one of the shift pad-
dles.

Active cruise control*
The concept
With active cruise control, you can select a 
desired speed which is not only automatically 
maintained when driving on open roadways, but 
also varied to maintain a selected distance set-
ting as slower traffic is encountered.
Active cruise control is a technological advance 
over the familiar cruise control and is a welcome 
relief from the constant adjustment of speed 
that can accompany driving in traffic on high-
ways or other high-speed thoroughfares. Espe-
cially on longer trips, the system can reduce 
fatigue and tension, while increasing your 
enjoyment of driving. Please use it safely and 
responsibly.
Within the limits of its capability, the system 
automatically adapts the car's speed to that of a 
slower vehicle in front of you. You can specify

Warning lamps
The indicator2 flashes in red; a 
signal sounds. 
The system indicates that you 
must brake and/or maneuver the 
vehicle yourself. Active cruise con-
trol cannot automatically restore the distance to 
the vehicle ahead. 
This indicator does not release you from your 
responsibility to adapt your desired speed and 
driving style to prevailing driving conditions.
The indicator 2 flashes in yellow. 
The prerequisites for operating 
active cruise control are not met, 
e.g. as a result of ABS or DSC 
interventions. Active cruise control 
is deactivated. You can reactivate the system, if 
desired, by tapping or pulling the lever when 
road and traffic conditions permit. It is not pos-
sible to resume a stored speed.
Radar sensor
The sensor's ability to detect vehicles ahead 
may be restricted as a result of heavy rain, dirt, 
snow or ice. If necessary, clean the radar sensor 
located in the front bumper, see arrow. Be sure 
to use particular care when removing any layers 
of snow or ice from the sensor.
When the radar sensor is not properly posi-
tioned, active cruise control cannot be activated 
at all.
Malfunction
The warning lamp comes on when 
the system has failed. A message 
appears on the Control Display. You 
can find more information starting on page83. 
System limitations
Always remember that the range and abil-
ity of the system does have physical limi-
tations. It will not apply the brakes or decelerate 
your vehicle when there is a slow-moving vehi-
cle, stopped vehicle or stationary object ahead 
of you, as for example, at a traffic light or a 
parked vehicle. Also, the system does not react 
to oncoming traffic, pedestrians or other types 
of potential traffic such as a rider on horseback. 
It is also possible that the system may not detect smaller moving objects such as motor-
cycles or bicycles. Be especially alert when 
encountering any of these situations as the sys-
tem will neither automatically brake, nor provide 
a warning to you. Also, be aware that every 
decrease in the distance setting allows your 
vehicle to come closer to a vehicle in front of 
you and requires a heightened amount of alert-
ness.<

In approaching a curve, it is possible that active 
cruise control would react briefly to a vehicle in 
the adjacent lane. In addition, the system can 
sense if your vehicle is in a curve and may not 
accelerate. If your vehicle decelerates in either 
case, you can choose to overcome the deceler-
ation by briefly pressing the accelerator pedal.
Your responsibility
Your actions have priority at all times. When you 
press the accelerator pedal while driving with 
active cruise control, the automatic braking 
function will be temporarily interrupted. Once 
you release the accelerator pedal, the desired 
speed or the selected distance to the vehicle 
ahead is achieved again.
Do not leave your foot on the accelerator 
pedal and make sure that no objects such 
as floor mats are lying on the accelerator pedal. 
Otherwise the system may not be able to brake 
the vehicle.<

A warning lamp will come on if the coolant, and 
therefore the engine, becomes too hot. In addi-
tion, a message will appear on the Control Dis-
play.
Check coolant level, refer to page228.
Engine oil temperature*
When the engine is at normal operating temper-
ature, the engine oil temperature is between 
approx. 2107/1006 and approx. 3007/
1506.
If the engine oil temperature is too high, a mes-
sage appears on the Control Display.

when you are driving in mountainous areas, for 
example, the indicator may fluctuate slightly.
Reserve
Once the fuel level has fallen to the reserve 
zone, a message briefly appears on the Control 
Display and the cruising range for the remaining 
amount of fuel is displayed on the computer. 
Under a cruising range of approx. 30 miles/
50 km, the message remains in the Control Dis-
play.
