If it is on, variable Speedtronic is already
selected. If it is not, press the cruise control lever in
the direction of arrow

LIM indicator lamp 2in the cruise control
lever lights up. Variable Speedtronic is
selected. G
Risk of accident
If there is a change of drivers, advise the
new driver of the limit speed stored.
Only use Speedtronic if you will not have to
accelerate suddenly to a speed above that
stored as the limit speed. You could other-
wise cause an accident.
You can only exceed the limit speed stored
if you deactivate variable Speedtronic:
R using the cruise control lever.
R by depressing the accelerator pedal
beyond the pressure point (kickdown).
It is not possible to deactivate variable
Speedtronic by braking.
Storing the current speed You can use the cruise control lever to limit
the speed to any speed above 30 km/h while
the engine is running. X
Briefly press the cruise control lever up
1 or down 4.
The current speed is stored. The stored
speed, e.g. LIM km/h, appears in the multi-
function display.
The segments in the speedometer from the
start of the scale up to the stored speed
light up.

the last stored speed G
Risk of accident
Only select a stored speed if you know what
that speed is and whether it is suitable for
the current driving and traffic situation.
Otherwise, sudden braking could endanger
you or others.

Variable Speedtronic is deactivated automat-
ically when you depress the accelerator pedal
beyond the pressure point (kickdown) but
only if your current speed does not differ by
more than 20 km/h from the stored speed.
You will hear a warning tone if this is the case. G
Risk of accident
It is not possible to deactivate variable
Speedtronic by braking.
i The last speed stored is cleared when you
switch off the engine.
Permanent Speedtronic i
Permanent Speedtronic is only available
for certain countries.
You can use the on-board computer to limit
the speed permanently to a value between
160 km/h (e.g. for driving with winter tyres)
and the maximum speed. Shortly before the stored speed is reached it
is shown in the multi-function display.
You cannot exceed the stored limit speed,
even if you depress the accelerator pedal
beyond the pressure point (kickdown).

HOLD relieves the strain on the driver:
R when pulling away, especially on steep
slopes
R when manoeuvring on steep slopes
R when waiting in traffic
The vehicle is kept stationary without the
driver having to depress the brake pedal.
The braking effect is cancelled and HOLD
deactivated when you depress the accelera-
tor pedal to pull away.
Activation conditions You can activate HOLD if:
R
the vehicle is stationary
R the engine is running
R the driver's door is closed
R the parking brake is not applied R
the bonnet is closed
R on vehicles with automatic transmission*,

are met.
X Depress the brake.
X Depress the brake again quickly until
HOLD appears in the display.
HOLD is activated. You can release the
brake pedal.
i If depressing the brake pedal the first
time does not activate HOLD, wait briefly
and then try again. G
Risk of accident
The vehicle's brakes are applied when
HOLD is activated. For this reason, deacti-
vate HOLD if the vehicle is to be set in
motion by other means (e.g. in a car wash
or by towing). Deactivating HOLD HOLD is deactivated if:
R
you accelerate. On vehicles with automatic
transmission*, only if the selector lever is
in position Dor R.
R the selector lever is moved to Pon vehicles
with automatic transmission*
R you release the brakes completely and
apply them again with a certain amount of
pressure until the HOLDmessage in the
multi-function display goes out G
Risk of accident
Never get out of the vehicle when HOLD is
activated.
HOLD must never be operated or deactiva-
ted by a passenger or from outside the
vehicle.
HOLD does not replace the parking brake
and must not be used for parking.

R open the bonnet
The horn draws your attention to the fact that
the vehicle has been parked while HOLD is
still activated. The sound becomes louder if
you attempt to lock the vehicle. The vehicle
is not locked until HOLD is deactivated.
i If the ignition has been switched off, the
engine cannot be restarted until HOLD is
deactivated.
If there is a fault in the system or power supply
while HOLD is activated, the Brake immedi-
ately message appears in the multi-function

Vehicle level Your vehicle automatically adjusts its ride
height to reduce petrol consumption and
improve driving safety.
The following vehicle levels are possible:
R
Normal
R Raised
R Lowered
The "Normal" and "Raised" vehicle levels can
be set manually.
The "Lowered" vehicle level is set automati-
cally:
R at speeds above 140 km/h
R if you have selected "Sports tuning I or
II" (Y page 157)

Select the "Normal" setting for normal road
surfaces and "Raised" for driving with snow
chains or on particularly poor road surfaces. G

Multi-function display
A message appears in the multi-function dis-
play for approximately five seconds once you
have selected a damping program, for exam-
ple: 4MATIC* (permanent four-wheel
drive)
4MATIC ensures that all four wheels are per-
manently driven. Together with ESP ®
, it
improves the traction of your vehicle when-
ever a drive wheel spins due to insufficient
grip. G
Risk of accident
4MATIC cannot reduce the risk of an acci-
dent if you drive too fast.
If a drive wheel spins due to insufficient
grip:
R Only depress the accelerator pedal as far
as necessary when pulling away.
R Accelerate less when driving.
R Adapt your driving style to suit road and
traffic conditions.
i In wintry driving conditions, the maximum
effect of 4MATIC can only be achieved if
you use winter tyres (M+S tyres), with snow
chains if necessary. Parktronic*
G
Risk of accident
Parktronic is only an aid and may not detect
all obstacles. It is not a substitute for atten-
tive driving.
You are always responsible for safety and
must continue to pay attention to your
immediate surroundings when parking and
manoeuvring. You could otherwise endan-
ger yourself and others. G
Risk of injury
Make sure that no persons or animals are
in the manoeuvring range. Otherwise, they
could be injured.
Parktronic is an electronic parking aid. It indi-
cates visually and audibly the distance
between your vehicle and an object.
Parktronic is automatically activated when
you switch on the ignition and release the
parking brake.
Parktronic is deactivated at speeds above
18 km/h. It is reactivated at lower speeds.
Parktronic monitors the area around your
vehicle using six sensors in the front bumper
and four sensors in the rear bumper. Controls

Pay particular attention to objects above
or below the sensors when parking, such
as flower pots or trailer towbars. Parktronic
does not detect such objects when they are
in the immediate vicinity of the vehicle. You
could damage the vehicle or the objects.
Ultrasonic sources such as an automatic
car wash, a lorry's compressed-air brakes
or a pneumatic drill could cause Parktronic
