If you leave the vehicle parked up for longer
than four weeks, the battery may be damaged
by exhaustive discharge.
X Disconnect the battery (Y page 348) or
connect it to a trickle charger.
i You can obtain information about trickle
chargers from a qualified specialist work-
shop, e.g. a Mercedes-Benz Service
Centre.
If you leave the vehicle parked up for longer
than six weeks, the vehicle may suffer dam-
age as a result of lack of use.
X Visit a qualified specialist workshop and
seek advice. Driving tips
General driving tips
Rolling with the engine switched off G
WARNING
Never switch the engine off while the vehicle
is in motion.
There is no power assistance for the steering
and the service brake when the engine is not
running.
You will require considerably more effort to
steer and brake, and you could therefore lose
control of the vehicle and cause an accident. Engine oil
! Vehicles with adiesel particle filter:
If the vehicle is mostly driven for short dis-
tances, it is possible that malfunctions may
occur during the automatic cleaning of the
diesel particle filter. This can lead to engine
damage. Therefore, if you frequently drive
short distances, make sure to drive on
motorways or country roads for 20 minutes
at least every 500 km. Brakes
Important safety notes G
WARNING
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. G
WARNING
Make sure that other road users are not
endangered by your braking.
Downhill gradients On long and steep downhill gradients, espe-
cially if the vehicle is laden or towing a trailer,
you must shift to a lower gear in good time or, Driving tips

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. G

tthe work required. Mercedes-Benz
recommends that you use aMercedes-Benz
Service Centre for this purpose. In particular,
work relevant to safety or on safety-related
systems must be carried out at a qualified
specialist workshop.
X Correct the tyre pressure if it is still at least
130 kPa (1.3 bar/20 psi) (for the values,
see the fuel filler flap).
X To increase the tyre pressure: switch on
the tyre inflation compressor. Example: TIREFIT kit, version 2
X
To reduce the tyre pressure: press pres-
sure release button :next to pressure
gauge ;.
X TIREFIT kit version 1: pull the tyre sealant
bottle from the recess of the tyre inflation
compressor.
X TIREFIT kit version 1: unscrew the hose
from the tyre inflation compressor to the
flange of the tyre sealant bottle. TIREFIT kit version 2 X
TIREFIT kit version 2: to remove the tyre
sealant bottle from the tyre inflation com-
pressor, press together the locking tabs on

i
If the wheel positions on the vehicle are
interchanged, the tyre pressures may be
displayed for the wrong positions for a
short time. 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.
i For an overview of the menus, see
(Y page 230).
If you wish to define the new reference values
manually:
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 361).
X Make sure that the key is in position 2in
the ignition lock.
X Press the =or; button on the steer-
ing wheel to select the Service menu.
X Press the 9or: button to select
Tyre pressure .
X Press the abutton.
The multifunction display shows the cur-
rent tyre pressure of the individual tyres or
the Tyre pressures will be dis‐ played after a few minutes of driv‐
ing message.
X Press the :button.
The Use current pressures as new reference values message appears in
the multifunction display. If you wish to confirm the restart:
X
Press the abutton.
The Tyre press. monitor restarted message appears in the multifunction dis-
play.
After you have driven for a few minutes, the
system checks whether the current tyre
pressures are within the specified range.
The new tyre pressures are then accepted
as reference values and monitored.
If you wish to cancel the restart:
X Press the %button.
The tyre pressure values stored at the last
restart will continue to be monitored.
Radio type approval for the tyre pres-
sure monitor In certain countries, a radio type approval for
the tyre pressure monitor may be required.
