mal operation of the vehicle. Servic ework will
need to be performed more often if the vehicle is operated under arduous conditions or increased
loads, for example:
R regular city driving with frequent intermediate
stops
R if the vehicle is primarily used to travel short
distances
R for frequent operation in mountainous terrain
or on poor road surfaces
R if the engine is often left idling for long periods
In these or similar operating conditions, have,
for example, the air filter, engine oil and oil filter changed more frequently. The tyres must be
checked more frequently if the vehicle is oper-
ated under increased loads. Further information can be obtained at aqualified specialist work-
shop, e.g. aMercedes-Benz Servic eCentre. Fuel/water separator

Operation with atrailer: thea pplicable value
for th erear axle is th emaximum value stated in
th et yrep ressure table.
The tyr epressure table may also state tyr epres-
sures for differen tload conditions. Thes eare
defined in th etable as differen tnumbers of pas-
sengers and amounts of luggage. The actual
number of seat smay differ fro mthis.
If tyr esizes are not specified ,the tyrep ressures
stated on th etyrep ressure informatio nlabel
apply for all tyres approved for this vehicle. If one or mor
etyre sizes precedes atyre pres-
sure, the following tyre pressure information is
valido nly for that tyre size.
Use asuitable pressure gauge to check the tyre
pressure. The outer appearance of atyre does
not give any reliable indicatio nofthe tyre pres-
sure.
You can also check the tyre pressure using the
on-board computer.
If possible, correct tyre pressures only when the
tyres are cold. The tyres are cold:
R if the vehicl ehas been parked with the tyres
out of direct sunlight for at least three hours
and
R if the vehicle has not been driven further than
1.6 km
Dependin gonthe outside temperature, the
vehicle speed and the load on the tyres, the tyre temperature and thus the tyre pressure changes by approximately 10 kPa (0.1 bar/1.5 psi )per
10 †. Take this into account when checking the
pressure of warm tyres. Correct the tyre pres-
sure only if it is too low for the current operating
condition.
Drivin gwithatyre pressure that is too high or
too low can:
R shorten the service life of the tyres
R cause increased tyre damage
R have anegative effect on handling character-
istics and thus driving safety (e.g. aquaplan-
ing)
The tyre pressure values given for low loads are minimum values that offer you good driving
comfor tcharacteristics.
However, you can also use the values given for
higher loads. These are permissible and will not
adversely affect the runnin gofthe vehicle. Tyre pressur
emonitor
General notes If
at yre pressure monitor is fitted, the vehicle's
wheelsh ave 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
functions only if the corresponding sensors are
fitted to all wheels.
Information on tyre pressures is shown on the
multifunction display. After afew minutes of
driving, the current tyre pressure of each wheel
is shown in the Serv.

For further information on displaying this mes-
sage, refe rtothe "Checking the tyre pressure
electronically" section (Y page 240).
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 situation
(Y page 238). Note that the correc ttyre pres-
sure for the current operating situation must
first be learnt by the tyre pressure monitor. If a
substantial loss of pressure occurs, the warning threshold for the warning message is aligned to
the learnt reference values. Restart the tyre
pressure monitor after adjusting to the cold tyre pressure (Y page 241). The current pressures
are saved as new reference values. This ensures that awarning message appears only if the tyre
pressure drops significantly.
The tyre pressure monitor does not warn you of
an incorrectly set tyre pressure. Observe the
notes on the recommended tyre pressure
(Y page 238).
The tyre pressure monitor is not abletow arn
you of asudden loss of pressure, e.g. if the tyre
is penetrated by aforeign object. In this event,
bring the vehicle to ahalt by braking carefully.
Avoid abrupt steering manoeuvres.
The tyre pressure monitor has ayellow h
warning lamp on the instrument cluster for indi-
cating apressure loss or malfunction. Depend-
ing on how the warning lamp flashe sorlights up,
at yre pressure that is too low or amalfunction in
the tyre pressure monitor is indicated:
R if the h warning lamp is lit continuously,
the tyre pressure on one or more tyres is sig-
nificantly too low. The tyre pressure monitor
is not malfunctioning.
R if the h warning lamp flashe sfor around a
minute and then remains lit constantly, the
tyre pressure monitor is malfunctioning.
In addition to the hwarning lamp,am essage
appears in the multifunction display. Observe
the information on display messages
(Y page 150).
It may take up to ten minutes for amalfunction
of the tyre pressure monitor to be indicated .A
malfunction willbei ndicated by thehtyre
pressure warning lamp flashing for approx-
imatel yone minute and then remaining lit. When
the faulth as been rectified, the htyre pres-
sure warning lamp goes out after driving for a
few minutes. The tyre pressure values indicated by the on-
board computer may differ from those meas-
ured at
afilling station using apressure gauge.
The tyre pressures shown by the on-board com-
puter refer to those measured at sea level. At
high altitudes, the tyre pressure values indica-
ted by apressure gauge are higher than those
shown by the on-board computer. In this case,
do not reduce the tyre pressures.
The operation of the tyre pressure monitor can
be affected by interferenc efrom radio transmit-
ting equipment (e.g. cordless headphones, two- way radios) that may be being operated in or
near the vehicle.

Restarting the tyre pressure monitor When you restart the tyre pressure monitor, all
existing warning messages are deleted and the
h
warning lamp goes out. The monitor uses
the currently set tyre pressures as the reference valuesf or monitoring. In most cases, the tyre

reference values manually as described here.
The tyre pressure monitor then monitors the
