If the ASSYST PLUS service interval display
has been inadvertently reset, this setting can
be corrected at a qualified specialist work-
shop.
Have service work carried out as described in the Maintenance Booklet. This may otherwise
lead to increased wear and damage to the
major assemblies or the vehicle.
A qualified specialist workshop, e.g. an author-
ized Mercedes-Benz Service Center, will reset
the ASSYST PLUS service interval display after
the service work has been carried out. You can
also obtain further information on maintenance work, for example.
Special service requirements The specified maintenance interval takes only
the normal operation of the vehicle into
account. Under arduous operating conditions or
increased load on the vehicle, maintenance
work must be carried out more frequently, for
example:
R Regular city driving with frequent intermedi-
ate stops
R If the vehicle is primarily used to travel short
distances R
Use in mountainous terrain or on poor road
surfaces
R If the engine is often left idling for long periods
R In racetrack mode
Under these or similar conditions, have, for
example, the air filter, engine oil and oil filter
replaced or changed more frequently. Under
arduous operating conditions, the tires must be
checked more often. Further information can be
obtained at a qualified specialist workshop, e.g. an authorized Mercedes-Benz Service Center.
i In racetrack mode, the vehicle is subject to
higher loads, meaning that additional main-
tenance work is required. If you plan race-
track use, consult a qualified specialist work-
shop first. Mercedes-Benz recommends that
you use an authorized Mercedes-Benz Ser-
vice Center for this purpose.
Driving abroad An extensive Mercedes-Benz Service network is
also available in other countries. You can obtain further information from any authorized
Mercedes-Benz Service Center. Care

the ground
It is important that you observe the safety
instructions when towing away your vehicle
(Y page 258).
The automatic transmission automatically shifts
to position 005Dwhen you open the driver's or
front-passenger door or when you remove the
SmartKey from the ignition lock. In order to
ensure that the automatic transmission stays in position 005Cwhen towing away the vehicle, you
must observe the following points:
X Insert the SmartKey into the ignition lock. You
must use the SmartKey instead of the Start/
Stop button (Y page 111).
X Start the engine and leave it running during
the entire towing procedure.
X Depress and hold the brake pedal.
X Move the transmission to position 005Cwith the
E-SELECT lever.
X Check the transmission position using the
indicator in the multifunction display

X Release the brake pedal.
X Release the electric parking brake.
X Switch on the hazard warning lamps
(Y page 98). In order to signal a change of direction when
towing the vehicle with the hazard warning
lamps switched on, use the combination switch as usual. In this case, only the indicator lamps
for the direction of travel flash. After resetting
the combination switch, the hazard warning
lamp starts flashing again. Transporting the vehicle
!
When the vehicle is loaded for transport, the
front and rear axles must be stationary and on the same transportation vehicle. Positioning
over the connection point of the transport
vehicle is not permitted. The drive train may
otherwise be damaged.
! You may only secure the vehicle by the
wheels, not by parts of the vehicle such as
axle or steering components. Otherwise, the
vehicle could be damaged.
The towing eye can be used to pull the vehicle
onto a trailer or transporter for transporting pur- poses.
X Insert the SmartKey into the ignition lock. You
must use the SmartKey instead of the Start/
Stop button (Y page 111).
X Start the engine and leave it running during
the entire loading operation.
X Move the transmission to position 005Cwith the
E-SELECT lever.

Towing and tow-startingBreakdown assistance

ensure that the replacement or alternate Tires
and wheels allow the TPMS to continue to
function properly.
It is the driver's responsibility to set the tire
pressure to that recommended for cold tires
which is suitable for the operating situation
(Y page 266). Note that the correct tire pressure
for the current operating situation must first be taught-in to the tire pressure monitor. If a sub-
stantial loss of pressure occurs, the warning
threshold for the warning message is aligned tothe taught-in reference values. Restart the tire
pressure monitor after adjusting the pressure of
the cold tires (Y page 271). The current pres-
sures are saved as new reference values. As a
result, a warning message will appear if the tire pressure drops significantly.
The tire pressure monitor does not warn you of
an incorrectly set tire pressure. Observe the
notes on the recommended tire pressure
(Y page 266).
The tire pressure monitor is not able to warn you of a sudden loss of pressure, e.g. if the tire 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
movements.
The tire pressure monitor has a yellow warning
lamp in the instrument cluster for indicating
pressure loss or a malfunction. Whether the
warning lamp flashes or lights up indicates
whether a tire pressure is too low or the tire
pressure monitor is malfunctioning:
R if the warning lamp is lit continuously, the tire
pressure on one or more tires is significantly
too low. The tire pressure monitor is not mal-
functioning.
R if the warning lamp flashes for around a
minute and then remains lit constantly, the
tire pressure monitor is malfunctioning.
In addition to the warning lamp, a message
appears in the multifunction display. Observe
the information on display messages
(Y page 192).
It may take up to ten minutes for a malfunction
of the tire pressure monitor to be indicated. A
malfunction will be indicated by the tire pres-
sure warning lamp flashing for approximately
one minute and then remaining lit. When the
malfunction has been rectified, the tire pressure warning lamp goes out after a few minutes of
driving. The tire pressure values indicated by the on-
board computer may differ from those meas-
ured at a gas station with a pressure gage. The
tire pressures shown by the on-board computer
refer to those measured at sea level. At high
altitudes, the tire pressure values indicated by a pressure gage are higher than those shown by
the on-board computer. In this case, do not
reduce the tire pressures.
The operation of the tire pressure monitor can
be affected by interference from radio transmit-
ting equipment (e.g. radio headphones, two-way radios) that may be being operated in or near the vehicle.

(Y page 192).
If the wheel positions on the vehicle are rotated,
the tire pressures may be displayed for the
wrong positions for a short time. This is rectified after a few minutes of driving, and the tire pres-
sures are displayed for the correct positions.
Restarting the tire pressure monitor When you restart the tire pressure monitor, all
existing warning messages are deleted and the
warning lamps go out. The monitor uses the cur-
rently set tire pressures as the reference values for monitoring. In most cases, the tire pressure
monitor will automatically detect the new refer-
ence values after you have changed the tire
pressure. However, you can also set reference
values manually as described here. The tire
pressure monitor then monitors the new tire
pressure values.
X Set the tire pressure to the value recommen-
ded for the corresponding driving situation on the Tire and Loading Information placard on
