Activating system As of ignition key position 2:
Press the button; the indicator lamp in
the instrument cluster comes on, refer
to page 22. You are able to use the
cruise control.
Do not use the cruise control
when driving on winding roads, in
heavy traffic or in poor road conditions
– e.g. snow, rain, ice, loose road sur-
face – that do not permit a constant
speed.<

Cruise control* Deactivating systemPress the button repeatedly until the
indicator lamp in the instrument cluster
goes out.
The cruise control is also deactivated
when the ignition key is turned into
position 0.
The speed stored in the memory is

accelerating Briefly press button
+:
The system maintains and stores the
current vehicle speed. Every time you
briefly press the button, the speed
increases by approx. 0.6 mph/1 km/h.
Press and hold button +:
The vehicle accelerates without pres-
sure on the accelerator pedal. When
you release the button, the system
maintains and stores the current speed.
If, on a downhill gradient, the
engine's braking effect is not suffi-
cient, the controlled speed can be
exceeded. Speed can drop on uphill
grades if the engine output is insuffi-
cient.<
Decelerating Briefly press button
–:
When cruise control is active, every
brief touch of the button reduces the
speed by approx. 0.6 mph/1 km/h.
Press and hold button –:
With the cruise control active, the sys-
tem automatically reduces the throttle
opening to slow the vehicle. When you
release the button, the system main-
tains and stores the current speed.
Interrupting cruise control When the system is activated, press
button 1. The indicator lamp stays on.
You can use the cruise control again
whenever required by calling up the
speed that was stored last.
In addition, cruise control is interrupted
automatically:
>When you apply pressure to the
brake pedal
>When you apply pressure to the
clutch pedal or when you move the
automatic transmission selector lever
from Drive to Neutral
>If you exceed or fall below the con-
trolled speed for an extended period,
by depressing the accelerator, for
example. Recalling stored setting Press button:
The vehicle accelerates to and main-
tains the last speed stored.

Ice warning If the outside temperature drops to
approx. +37.57/+36, a signal sounds
as a warning and the display flashes for
a brief period.
The ice warning does not alter the
fact that surface ice can form at
temperatures above +37.57/+36, on

Antilock Brake System DSC Dynamic Stability Control MalfunctionBe sure to observe the information on
the lamp combination which may light
up on page 20.
The concept DSC maintains vehicle stability, even in
critical driving situations.
The DSC is operational every time you
start the engine.
The system optimizes the driving stabil-
ity during acceleration and when start-
ing from a standstill. The system recog-
nizes any tendency for the vehicle to
assume an unstable attitude such as
oversteer or understeer; it then coun-
teracts this tendency with a combina-
tion of graduated reductions in engine
torque and selective braking interven-
tion at individual wheels. DSC provides
optimized stability within the limits
defined by the laws of physics.
The laws of physics cannot be
repealed, even with DSC. An
appropriate driving style always
remains the responsibility of the driver.
We therefore urge you to avoid using
the additional safety margin of the sys-
tem as an excuse for taking risks.
Do not make any modifications to the
DSC system. Never allow anyone other
than authorized professional techni-
cians to carry out service or repairs on
the system.<
Indicator lamps The indicator lamps in the instrument
cluster goes out shortly after you switch
on the ignition,
The indicator lamp flashes:
DSC is active and governs drive
and braking force.
The indicator lamp stays lit:
DSC has been switched off using the
button and the stabilizing interventions
are no longer available.

Flat Tire MonitorThe concept The Flat Tire Monitor keeps track of the
inflation pressures in the four fitted tires
as you drive. The system provides an
alert whenever the inflation pressure
drops significantly in relation to the
pressure another tire.
The check of the tire inflation pressure
is based on monitoring the relative
speeds of the wheels. A flat is detected
and reported on the basis of a deviation
in certain speed ratios.Functional requirementTo ensure reliable operation, the sys-
tem should have been initialized with
the correct tire inflation pressure.
System limits
The Flat Tire Monitor cannot indi-
cate sudden severe tire damage
caused by outside factors and does not
detect a natural, even pressure drop in
all four tires.<
In the following situations, the system
could be delayed or malfunction:
>When driving on snow-covered or
slippery road surfaces
>In the case of performance-oriented
driving: slip on the drive wheels, high
lateral acceleration
>False alarms and undetected loss of
pressure may occur when you are
driving with snow chains fitted.
Initializing system
Perform the initialization immedi-
ately every time you correct the
inflation pressure, change a tire or
change a wheel or all wheels. A drive
is required for this purpose.<
1. Start the engine, but do not drive off
2. Press the button until the yellow indi-
cator lamp in the instrument cluster
lights up for a few seconds
3. Drive off.
It takes a few minutes of driving until
the Flat Tire Monitor can detect and
indicated a flat tire.
When driving with snow chains,
do not initialize the system.<

Briefly press the button once again to
switch on/off.
The parking lamps or low beams
must be switched on for the fog
lamps to operate. A green indi-
cator lamp appears in the instrument
cluster to indicate that the front fog
lamps are on.
If the high beams are switched on, the
front fog lamps go out.
If the automatic headlamp control
is activated, the low beams will
automatically be switched on when the
front fog lamps are switched on.<530us210

Roller sun blinds for rear side

Use the strap to pull out the blinds, then
hook them in the provided attachment.
With roller sun blinds attached, do
not open the windows during
travel. The blinds may otherwise be
damaged by the wind.<
You can use this system to ventilate the
interior and lower its temperature, using
the blower of the independent ventila-
tion or of the automatic climate control.
The independent ventilation is operated
via the MID Multi-Information Display,
refer to page 86 or via the onboard
computer, refer to the separate
Owner's Manual.
You can set two different times for the
system to start; it will remain active for
30 minutes. You can also switch it on
and off directly. Since the system uses
a substantial amount of electrical cur-
rent, you should refrain from switching
it on twice in succession without allow-
ing the battery to be recharged in nor-
mal operation between use.When a preselected activation time is
set, the independent ventilation is oper-
ational at outside temperatures above
607/166, or by direct switch activa-
tion.
The air enters the passenger compart-
ment through the vent outlets in the
instrument cluster, which can be
adjusted for both direction and airflow.
Therefore, the vent outlets must be
open for the independent ventilation to
operate.
