i After using it several times in short suc-

4MATIC ensures that all four wheels are per-
manently driven. Together with ESP ®
, it
improves the traction of your vehicle when-
ever a drive wheel spins due to insufficient
grip.
If you fail to adapt your driving style, 4MATIC
can neither reduce the risk of an accident nor override the laws of physics. 4MATIC cannot
take account of road, weather and traffic con-
ditions. 4MATIC is only an aid. You are
responsible for the distance to the vehicle in
front, for vehicle speed, for braking in good
time, and for staying in lane.
If a drive wheel spins due to insufficient grip:
R when pulling away, only depress the accel-
erator pedal as far as is necessary.
R accelerate less when driving.
! Never tow the vehicle with one axle
raised. This may damage the transfer case. Damage of this sort is not covered by the
Mercedes-Benz implied warranty. All
wheels must remain either on the ground or
be fully raised. Observe the instructions for towing the vehicle with all wheels in full
contact with the ground.
i In wintry driving conditions, the maximum
effect of 4MATIC can only be achieved if
you use winter tyres (M+S tyres), with snow
chains if necessary. PARKTRONIC
Important safety notes PARKTRONIC is an electronic parking aid with
ultrasonic sensors. It monitors the area
around your vehicle using six sensors in the
front bumper and six sensors in the rear
bumper. PARKTRONIC indicates visually and
audibly the distance between your vehicle
and an object.
PARKTRONIC is only an aid. It is not a substi- tute for your attention to the immediate sur-
roundings. The responsibility for safe 188

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 recommended 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
pressures (Y page 330).

General notes If a tyre pressure monitor system is fitted, the
vehicle's wheels have sensors fitted that
monitor 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 pressure 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 multi-
function display. Example: current tyre pressure display
For further information on displaying this
message, refer to the "Checking the tyre pres-
sure electronically" section (Y page 333).
Important safety notes It is the driver's responsibility to set the tyre
pressure to the recommended cold tyre pres-
sure suitable for the operating conditions
(Y page 330). Note that the correct tyre pres-
sure for the current operating situation must 332

Warning messages of the tyre pressure monitor If the tyre pressure monitor detects a pres-

sage is shown in the multifunction display and the yellow tyre pressure monitor warning light
comes on.

Observe the instructions and safety notes in
the display messages in the "Tyres" section
(Y page 256).
i If the wheel positions on the vehicle are
interchanged, for a short time the tyre pres- sures may be displayed for the wrong posi-
tions. This is rectified after a few minutes of driving and the tyre pressures are displayed for the correct positions.
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 currently set tyre pressures as the refer-
ence values for monitoring. In most cases, the tyre pressure monitor will automatically
detect the new reference values after you
have changed the tyre pressure. However, you can also define reference values man-
ually 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
correctly in all four tyres for the current
operating conditions.
Also observe the notes in the section on
tyre pressures (Y page 330).
