weight must not exceed the maximum per-
missible gross vehicle weight of your vehicle. G
WARNING
The vehicle is braked when the HOLD function
or DISTRONIC PLUS is activated. Therefore,
deactivate HOLD and DISTRONIC PLUS if the
vehicle is to be towed.
It is better to have the vehicle transported
than to have it towed.

Tyre pressure
Tyre pressure specifications
Yo uw illf ind atable of tyr epressures for var-
ious operating conditions on the insid eof
your vehicle's fuel fille rflap.
Operation with emergency spare wheel:
The applicable value for the emergency spare
wheel is stated on the spare wheel and in the
technical data section.
Operation with atrailer: The applicable
value for the rear tyre sisthe maximum tyre
pressure value stated on the table insid ethe
fuel filler flap.
The table insid ethe fuel filler flap may state
tyre pressures for differen tload conditions.
These are defined in the table as different
numbers of passengers and amounts of lug-
gage. The actual number of seats may vary –
for more information please refer to the vehi-
cle's registration documents.
If no other data is stated, the tyre pressures
specified on the fuel filler flap apply for all
tyres approved for this vehicle. If
at yre size precedes atyre pressure, the tyre
pressure information following is only valid
for that tyre size. Instead of the complete tyre size, the rim
diameter alone, for example
R16,may be lis-
ted. Rim diameter
:is part of the tyre size and
can be found on the tyre sidewall. G
WARNING
Tyre pressure that is either too high or too low
has anegative effect on the vehicle's driving
safety, which could lead you to cause an acci-
dent. Therefore, you should regularly check
the pressure of all the tyres, particularly prior
to long trips, and correc tthe pressure as nec-
essary.
To test tyre pressure, use asuitable pressure
gauge. The outer appearance of atyre does
not permit any reliablec onclusion about the
tyre pressure. G
WARNING
Do not fit anything else to the tyre valve other
than the standard valve cap. In particular, ret-
rofitted tyre pressure monitors which are
screwed on to the valve may overload it and
cause it to fail. Due to their design, the valve Tyrep
ressure
321Wheels and tyres
Z

is kept open continuously, which may lead to
air loss. G
WARNING
Should the tyre pressure drop repeatedly:
R chec kthe tyre for foreign bodies.
R check whether the wheel is losing air or the
valve is leaking.
R make sure that only avalve cap approved
by Mercedes-Ben zisfitted on the tyre
valve.
Tyre pressures that are too low have anega-
tive effect on vehicle safety, which could lead
you to cause an accident.
If possible, only correct tyre pressures when
the tyres are cold. The tyres are cold when
the vehicle has been parked for at least three
hours or has been driven less than 1.5 km.
Depending on the ambient temperature, the
speed you are driving at and the load on the
tyres, the tyre temperature and thus the tyre
pressure may change by approximately
10 kPa (0.1 bar/1.5 psi) per 10 †. Take this
into account when checking the pressure of
warm tyres and only correct it if it is too low
for the current operating conditions.
Driving with tyre 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 charac-
teristics and thus the driving safety (e.g. by
causing aquaplaning)
i The tyre pressure values given for low
loads are minimum values which offer you
good ride comfort characteristics.
However, you can also use the values given
for higher loads. These are permissible and
will not adversely affect the running of the
vehicle. H
Environmental note
Check the tyre pressure regularly,atl east
every 14 days. Tyrep
ressur eloss warning system
Important safety notes While the vehicle is in motion, the tyre pres-
sure loss warning system monitors the set
tyre pressure using the rotational speed of
the wheels. This enables the system to detect
significant pressure loss in
atyre. If the speed
of rotation of awheel changes as aresult of
al oss of pressure, acorresponding warning
message will appearint he multifunction dis-
play. G
WARNING
The tyre pressure loss warning system does
not warn you of an incorrectly set tyre pres-
sure. The table on the inside of the fuel filler
flap will help you decide whether the tyre
pressures should be corrected.
The tyre pressure loss warning system does
not replace the need to regularly check your
vehicle's tyre pressures, since an even loss of
pressure on several tyres at the same time
cannot be detected by the tyre pressure loss
warning system.
The tyre pressure monitor is not able to warn
you of asudden loss of pressure, e.g. if the
tyre is penetrated by aforeign object.
In the event of asudden loss of pressure, bring
the vehicle to ahalt by braking carefully. Do
not make any sudden steering movements
when doing so.
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 conditionsa re wintry.
R you are driving on sand or gravel.
R you adopt avery sporty driving style (cor-
nering at high speeds or driving with high
rates of acceleration).
R you are towing avery heavy or large trailer.
R you are driving with aheavy load (in the
vehicle or on the roof). 322
