cle could start to skid.
R if the sensors are dirty or there is poor
visibility, e.g. due to snow, rain or fog.
Distance control may be impaired.
Always pay attention to traffic conditions
even when Distronic is activated. Other-
wise, you may fail to recognise danger in
time, could cause an accident and injure
yourself and others.
If there is no vehicle in front, Distronic oper-
ates in the same way as cruise control. Dis-
tronic functions in the 30 km/h to
180 km/h range. G
Risk of accident
Distronic brakes your vehicle at a maximum
of 2 m/s 2
, depending on its speed. This
corresponds to approximately 20% of your
vehicle's maximum braking power. You
must also apply the brakes yourself if this
braking power is not sufficient.
If Distronic detects a risk of collision with a
vehicle in front, an intermittent warning
tone sounds. In addition, the ldistance
warning lamp in the instrument cluster
lights up. Brake to avoid a collision. Cruise control lever You can operate Distronic and variable
Speedtronic with the cruise control lever.

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.

Variable Speedtronic is deactivated automat-
ically when you depress the accelerator pedal

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).

The rear axle level control regulates the vehi-
cle level at the rear axle. The benefit of this is
that the vehicle level at the rear axle is kept
constant regardless of the load.

X Before restarting, consult the table of tyre
pressures on the inside of the fuel filler flap
to ensure that the tyre pressure in all four
tyres is set correctly for the operating con-
ditions concerned.
X Also observe the notes in the section on
tyre pressures (Y page 226). G
Risk of accident
The tyre pressure loss warning system can
only give reliable warnings if you have set
the correct tyre pressure. If an incorrect tyre pressure is set, these
incorrect values will be monitored.
A tyre with insufficient pressure results in
vehicle instability when driving, thus
increasing the risk of an accident.

The tyre pressure values stored at the last
restart will continue to be monitored. Checking the tyre pressure electroni-
cally*
The tyre pressure monitor only functions if
the correct wheel electronics are fitted to all
wheels. These monitor the pressure in all four
tyres, which you have set when restarting the
tyre pressure monitor. The monitor warns you
when the pressure drops in one or more of
the tyres. G
Risk of accident
The tyre pressure monitor does not warn
you of an incorrectly set tyre pressure. The
table on the inside of the fuel filler flap will
help you decide whether the tyre pressures
should be corrected.
The tyre pressure monitor is not able to
warn you of a sudden loss of pressure, e.g. Operation
