Selecting variable Speedtronic X
Check whether LIM indicator lamp 2is on.
If it is on, variable Speedtronic is already
selected.
If it is not, press the cruise control lever in
the direction of arrow 5.
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 when you do not have
to accelerate suddenly to a speed higher
than the stored limit speed allows. You
could otherwise 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. G
Risk of injury
Variable Speedtronic brakes automatically
in order to avoid exceeding the set speed.
As it does so, the brake pedal is depressed.
Do not place your foot under the brake
pedal as it could become trapped.
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 4to the pressure point.
The current speed is stored and shown in
the multi-function display.
The LIM indicator lamp in the instrument
cluster lights 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.
X Briefly pull the cruise control lever towards
you 3.

Deactivating variable Speedtronic There are several ways to deactivate variable
Speedtronic:
X Briefly press the cruise control lever for-
wards 6.

cluster goes out.
or
X Briefly press the cruise control lever in the
direction of arrow 5.
LIM indicator lamp 2in the cruise control
lever goes out. Variable Speedtronic is
deactivated.
Cruise control or Distronic* is selected.
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
in 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.
Just before the stored speed is reached, it
appears in the multi-function 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).

Risk of accident
Off-road level 3 is not permitted for use on
public roads. Off-road level 3 gives your
vehicle a very high centre of gravity. This
increases the risk of the vehicle tipping

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 activated automatically when
you:
R
switch on the ignition
R release the parking brake
R shift the automatic transmission to D,Ror
N
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. 1
