142 Speedtronic
Speedtronic brakes automatically so that you
do not exceed the set speed. On long and
steep downhill gradients, especially if the
vehicle is laden, you must select shift range
1, 2 or 3 in good time. In this way you will
make use of the braking effect of the engine,
which relieves the load on the brake system
and prevents the brakes from overheating
and wearing too quickly. If you need addi-
tional braking, depress the brake pedal
repeatedly rather than continuously. G
Risk of accident
Never depress the brake pedal continu-
ously while the vehicle is in motion, e.g.
never cause the brakes to rub by applying
constant slight pedal pressure. This causes
the brake system to overheat, increases
the braking distance and can lead to the
brakes failing completely. G
Risk of accident
Do not change down for additional engine
braking on a slippery road surface. This
could cause the drive wheels to lose their
grip and the vehicle could skid. You can set a variable or permanent limit
speed:
R
Variable for speed limits, e.g. in built-up
areas
R Permanent for long-term speed restric-
tions, e.g. for driving on winter tyres
(Y page 144) G
Risk of accident
Speedtronic is only an aid designed to
assist driving. You are responsible for the
vehicle's speed and for braking in good
time.
i The speed indicated in the speedometer
may differ slightly from the limit speed
stored.
Variable Speedtronic With the cruise control lever you can operate
cruise control, Distronic* and variable
Speedtronic.
The LIM indicator lamp on the cruise control
lever indicates which system you have selec-
ted:
R
LIM indicator lamp off: Cruise control or Distronic* is selected
R LIM indicator lamp lit:
variable Speedtronic is selected
You can use the cruise control lever to limit
the speed to any speed above 30 km/h while
the engine is running. 1

Selecting variable Speedtronic X
Check whether LIM indicator lamp 2 is 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 2 in 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 variable Speedtronic if you are
sure that you will not have to accelerate
suddenly to a speed above that stored as
the

limit speed, otherwise you could cause
an accident.
You can only exceed the limit speed stored
if you deactivate variable Speedtronic:
R using the cruise control lever
R if you depress 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.
Selecting the current or last stored
speed X
Briefly pull the cruise control lever towards
you 3.
Adjustment in 10 km/h increments X
Briefly press the cruise control lever up
1 for a higher speed or down 4 for a
lower speed.
or
X Keep the cruise control lever pressed until
the desired speed is set. Press the cruise control lever, up 1 for a higher speed or
down 4 for a lower speed.

For a higher speed: briefly pull the cruise
control lever towards you 3.

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 147)
R if you have selected "Comfort tun-
ing" (Y page 147) and then lock the vehicle within 60 seconds of the engine being
switched off G
Risk of injury
If you have selected “Comfort tuning”, the
vehicle will be lowered if you lock it within
60 seconds of the engine being switched
off. Make sure, therefore, that nobody is in
the vicinity of the wheel housing or under
the vehicle when you lock the vehicle. Oth-
erwise, limbs could become trapped.
! If you have selected “Comfort tuning”,
the vehicle will be lowered if you lock it
within 60 seconds of the engine being
switched off. Make sure when parking that
you stop your vehicle so that it does not
make contact with the kerb as it descends.
Your vehicle could otherwise be damaged.
Setting the vehicle level manually
Select the "Normal" setting for normal road
surfaces and "Raised" for driving with snow
chains or on particularly poor road surfaces. G
Risk of injury
Make sure that nobody is in the vicinity of
the wheel housing or under the vehicle
while lowering the vehicle when it is sta- tionary. Otherwise, limbs could become
trapped.

If indicator lamp 2 is lit:
X Press button 1.
Indicator lamp 2 goes out. The vehicle is
adjusted to the normal level.
i The "Raised level" setting is cancelled at
vehicle speeds above 120 km/h or if the
speed has been between 80 km/h and
120 km/h for more than approximately
5 minutes. If you do not drive within this
speed range, the raised level remains
stored, even when the key is removed from
the ignition lock.
Comfort or sports tuning AIRMATIC DC (dual control) comprises two
components: the Adaptive Damping System
(ADS) and spring stiffness adjustment.
ADS automatically regulates the suspension
as appropriate to particular driving condi-
tions. Parallel to this, the spring stiffness
switches between "comfort" and "sports" lev-
els. The damping/spring stiffness settings are
dependent on:
R
your driving style
R the road surface conditions
R your individual selection
Your selection remains stored even if you
remove the key from the ignition lock. 1

!
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
to malfunction.
Minimum distance Centre Approximately 20 cm

warning displays light up and a tone sounds.
If the distance falls below the minimum clear-
ance, it may no longer be shown.
Warning displays
The warning displays show the distance
between the sensors and the obstacle. The
warning display for the front area is located
on the dashboard above the centre air vents.
