i The last speed stored is cleared when you
switch off the engine.
Permanent SPEEDTRONIC
You can use the on-board computer to limit
the speed permanently to a value between
160 km/h(e.g. for driving on winter tyres) and the maximum speed (Y page 333).
Shortly before the stored speed is reached, it
appears in the multifunction display.
Permanent SPEEDTRONIC remains active,
even if variable SPEEDTRONIC is deactivated.
You cannot exceed the stored limit speed,
even if you depress the accelerator pedal
beyond the pressure point (kickdown). DISTRONIC PLUS
General notes DISTRONIC PLUS regulates the speed and
automatically helps you maintain the dis-
tance to the vehicle detected in front. Vehi-
cles are detected with the aid of the radar
sensor system. DISTRONIC PLUS brakes
automatically so that the set speed is not
exceeded.
Change into a lower gear in good time on long
and steep downhill gradients. Take particular note of this when driving a laden vehicle. By
doing so, you will make use of the braking
effect of the engine. This relieves the load on the brake system and prevents the brakes
from overheating and wearing too quickly.
If DISTRONIC PLUS detects that there is a risk
of a collision, you will be warned visually and acoustically. Without your intervention,
DISTRONIC PLUS cannot prevent a collision.
An intermittent warning tone will then sound
and the distance warning lamp will light up in
the instrument cluster. Brake immediately to
increase the distance to the vehicle driving in
front, or take evasive action, provided it is
safe to do so.
DISTRONIC PLUS operates in the range
between 0 km/h and 200 km/h.
Do not use DISTRONIC PLUS while driving on roads with steep gradients.
Important safety notes G
WARNING
DISTRONIC PLUS does not react to:
R people or animals
R stationary obstacles on the road, e.g. stop-
ped or parked vehicles
R oncoming and crossing traffic
As a result, DISTRONIC PLUS may neither give
warnings nor intervene in such situations.
There is a risk of an accident.
Always pay careful attention to the traffic sit- uation and be ready to brake. G
WARNING
DISTRONIC PLUS cannot always clearly rec-
ognise other road users and complex traffic
conditions.
In such cases, DISTRONIC PLUS may:
R give an unnecessary warning and then
brake the vehicle
R neither give a warning nor intervene
R accelerate or brake unexpectedly
There is a risk of an accident.
Continue to drive carefully and be prepared to
brake, particularly if DISTRONIC PLUS warns
you. 236

Activating DISTRONIC PLUS Activation conditions
To activate DISTRONIC PLUS, the following
conditions must be fulfilled:
R the engine must be running. It may take up
to two minutes of driving before
DISTRONIC PLUS is ready for use.
R the electric parking brake must be
released.
R ESP ®
must be switched on, but not inter-
vening.
R Active Parking Assist must not be activa-
ted.
R the transmission must be in position D.R
the driver's door must be closed when you
shift from Pto Dor your seat belt must be
fastened.
R the front-passenger door and the rear
doors must be closed.
R the DISTRONIC PLUS function must be
selected with the cruise control lever
(Y page 238).

X Remove your foot from the accelerator
pedal.
Your vehicle adapts its speed to that of the
vehicle in front, but only up to the desired
stored speed.

pedal, the DISTRONIC PLUS suspended DISTRONIC PLUS suspended
message appears in the multifunction dis-
play. The set distance to a slower-moving
vehicle in front will then not be maintained. The position of the accelerator pedal will
determine the speed.
You can also activate DISTRONIC PLUS when
stationary. The lowest speed that can be set is 30 km/h.

R
the electrical system in the engine com-
partment, the battery or the fuses have
been tampered with.
R the battery is disconnected.
R the accelerator pedal has been depressed,
e.g. by a vehicle occupant.
There is a risk of an accident.
If you wish to exit the vehicle, always turn off
DISTRONIC PLUS and secure the vehicle
against rolling away.
Further information on deactivating
DISTRONIC PLUS (Y page 243).
If DISTRONIC PLUS detects that the vehicle in
front is stopping, it brakes your vehicle until it is stationary.
Once your vehicle is stationary, it remains
stationary and you do not need to depress the
brake.
i After a short period, the vehicle is secured
by the electric parking brake, thus relieving
the service brake.
i Depending on the specified minimum dis-
tance, your vehicle will come to a standstill
at a sufficient distance behind the vehicle in
front. The specified minimum distance is
set using the control on the cruise control
lever.
When DISTRONIC PLUS is activated, the
transmission is shifted automatically to posi- tion Pif:
R the driver's seat belt is not fastened and the
driver's door is open

Press the cruise control lever up :for a
higher speed or down ;for a lower speed.
X Keep the cruise control lever pressed until
the desired speed is reached.
X Release the cruise control lever.

is activated and adjusts the vehicle's speed to the new speed stored.
X To adjust the set speed in 1 km/h incre-
ments: briefly press the cruise control
lever up :or down ;to the pressure
point.
The last stored speed increases or decrea- ses in 1 km/h increments.

General notes i
DSR (Downhill Speed Regulation) is only
available for vehicles with the Off-Road
Engineering package.
DSR is an aid to assist you when driving down-
hill. It keeps the speed of travel at the speed
selected on the on-board computer. The
steeper the downhill gradient, the greater the
DSR braking effect on the vehicle. When driv-
ing on flat stretches of road or on an uphill
gradient, the DSR braking effect is minimal or
non-existent.
DSR controls the vehicle’s speed when it is
activated and the transmission is in position
D, Ror N. By accelerating or braking, you can
always drive at a higher or a lower speed than that set on the on-board computer.
Important safety notes G
WARNING
If the speed driven and the set speed deviate and you activate DSR on a slippery road sur-
face, the wheels may lose traction. This 248

rking

Changing the set speed while the vehi-
cle is in motion When DSR is activated, you can change the
set speed to a value between 2 km/h and
18 km/h while the vehicle is in motion.
X To increase or reduce the set speed in
1 km/h increments: briefly press the
cruise control lever to the pressure point,
up : for a higher or down ;for a lower set
speed.
The set value appears in the status indica-
tor of the multifunction display. Off-road program

General notes AIR BODY CONTROL is an air suspension sys-
tem with variable damping for improved driv-
ing comfort. All-round level control ensures
the best possible suspension and constant
ground clearance, even with a laden vehicle.
When you drive fast, the vehicle is lowered
automatically to improve driving safety and to reduce fuel consumption. There is also the option to manually adjust the vehicle level.
AIR BODY CONTROL consists of level setting,
level control and the Adaptive Damping Sys-
tem ADS.
The vehicle level can be set using the
DYNAMIC SELECT switch (Y page 195) or the
level button (Y page 252). The setting always
corresponds to the last selected function.
