The vehicle level can be set using the DYNAMIC SELECT controller (Y page 140) or the on-board
computer (Y page 178). The setting always cor-
responds to the last selected function.
In order to reduce fuel consumption and
improve the driving dynamics, the vehicle is low-
ered as its speed increases. In the Sportand
Sport Plus drive programs it is lowered by up to
13 mm, and in the Comfortdrive program by up
to 5 mm compared to the normal vehicle level.
As the speed is reduced, the vehicle is raised to
the set vehicle height.
If the ignition is switched off for less than four
hours, the previously selected drive program is
activated when the engine is next started. If the
ignition is switched off for more than four hours,
the Comfort drive program is activated when
the engine is next started.
Select the normal level for normal road surfaces and the raised level for driving with snow chains
or on particularly poor road surfaces. Important safety notes
The vehicle is slightly lowered when the engine
is switched off. G
WARNING
People's limbs may become trapped if they
are located underneath the vehicle or
between the vehicle body and the tyres when the vehicle is lowering. There is a danger of
injury.
When lowering the vehicle, make sure no one
is underneath the vehicle or in the immediate vicinity of the wheel arches.
! If you have selected the normal level and
switched the engine off, the vehicle is low-
ered. The vehicle is automatically lowered by approximately 10 mm. Make sure when park- ing that you position your vehicle so that it
does not make contact with the kerb as the
vehicle is lowered. Your vehicle could other-
wise be damaged.

Important safety notes
The tyre pressure warning system does not warn
you of an incorrectly set tyre pressure. Observe
the notes on the recommended tyre pressure
(Y page 307).
The tyre pressure loss warning does not replace
the need to regularly check the tyre pressures.
An even loss of pressure on several tyres at the
same time cannot be detected by the tyre pres- sure loss warning system.
The tyre pressure monitor is not able to warn
you of a sudden loss of pressure, e.g. if the tyre
is penetrated by a foreign object. In the event of
a sudden loss of pressure, bring the vehicle to a halt by braking carefully. Avoid abrupt steering
manoeuvres.
The function of the tyre pressure loss warning
system is limited or delayed if:
R snow chains are fitted to your vehicle's tyres.
R road conditions are wintry.
R you are driving on sand or gravel.
R you adopt a very sporty driving style (corner-
ing at high speeds or driving with high rates of
acceleration).
R you drive with a heavy load.
Restarting the tyre pressure loss warn-
ing system Restart the tyre pressure loss warning system if
you have:
R changed the tyre pressure
R changed the wheels or tyres
R fitted new wheels or tyres
X Before restarting, make sure that the tyre
pressures are set properly on all four tyres for
the respective operating conditions. The rec-
ommended tyre pressures can be found in the
tyre pressure table on the fuel filler flap.
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.
X Observe the notes in the section on tyre pres-
sures (Y page 307).
X Make sure that the key is in position 2in the
ignition lock (Y page 132).

General notes If a tyre pressure monitor system is fitted, the
vehicle's wheels have sensors fitted that moni-
tor the tyre pressures in all four tyres. The tyre
pressure monitor warns you if the pressure
drops in one or more of the tyres. The tyre pres- sure monitor only functions if the corresponding
sensors are fitted to all wheels.
Information on tyre pressures is shown in the
multifunction display. After a few minutes of
driving, the current tyre pressure of each tyre is
shown in the Service Servicemenu of the multifunction
display. Tyre pressure

tyre pressure of the wheel that has been
removed. If this occurs, note that the value dis-
played for the position where the spare wheel is fitted is not the same as the current tyre pres-
sure of the emergency spare wheel.
Warning messages of the tyre pressure monitor If the tyre pressure monitor detects a pressure
loss in one or more tyres, a warning message is
shown in the multifunction display. The yellow
tyre pressure warning lamp then lights up:
R If the Rectify tyre pressure
Rectify tyre pressure message
appears in the multifunction display, the tyre
pressure in at least one tyre is too low. The
tyre pressure must be corrected when the
opportunity arises.
R If the Check Check tyre(s)
tyre(s) message appears in the
multifunction display, the tyre pressure in at
least one tyre has dropped significantly. The
tyres must be checked.
R If the Warning tyre defect
Warning tyre defect message
appears in the multifunction display, the tyre
pressure in at least one tyre has dropped sud- denly. The tyres must be checked.
Observe the instructions and safety notes in the display messages in the "Tyres" section
(Y page 237).
If the position of the wheels are interchanged on
the vehicle, the tyre pressures may be displayed
in the wrong positions for a short time. After a
few minutes of driving, this is rectified and the
tyre pressures are displayed in the correct posi- tions.
Restarting the tyre pressure monitor When you restart the tyre pressure monitor, all
existing warning messages are deleted and the
warning lamps go out. The monitor uses the cur-
rently set tyre pressures as the reference values for monitoring. In most cases, the tyre pressure
monitor will automatically detect the new refer- ence values after you have changed the tyre
pressure. However, you can also set reference
values manually as described here. The tyre
pressure monitor then monitors the new tyre
pressure values.
X Use the table on the inside of the fuel filler flap
to ensure that the tyre pressure is set cor-
rectly in all four tyres for the current operating conditions. Also observe the notes in the section on tyre
pressures (Y page 307).
X Make sure that the key is in position 2in the
ignition lock.
