Tyres and wheels
The tyre pressure loss warning system is
restricted in its function ordelayed if:
! snow chains are fitted to your vehicle
! road and traffic con ditions are affected
by wintry conditions
! you are driving ove ra loose surface
(e.g. sand or gravel)
! you adopt a sporty driving style (with
high cornering speed or rapid accelera-
tion)
! you are driving with a very heavy or
large trailer
! you are driving with roof loads or very
heavy loads Reactivating the
tyre pressure loss warning feature
You must reactivate the tyre pressure
loss
warning featur ein the following cases, if
you:
! have changed the tyre pressure
! have changed the wheels or tyres
! have fitted new wheels or tyres
6 Before reactivating, make sure that the
tyre pressure of all four tyres is set cor-
rectly for local driving conditions using
the table on the inside of the fuel filler
flap.
6 Make sure that the ignition is switched
on. G
Riskofaccident The tyre pressure loss warning system does
not warn
youof an inco rrectly set tyre pres-
sure. The table on the inside of the fuel filler
flap will help you to decide whether the tyre
pressur eshould be corrected.
The tyre pressure loss warning system isnot
a substitute for check ing the tyre pressures
on a regular basis sin ceequal pre ssureloss
in all fo urtyres cannot be detected by the
tyre pressure loss warning system.
Th etyre pressure loss warning system isnot
able to warn you of a sudden loss of pres-
sure, e.g. following penet ration by aforeign
obje ct. In such cases ,stop th evehicle by
braking carefully. Do notma keany sudden
steering movements. G
Risk of accident Th
ety re pre ssureloss warning system can
only work reliably if you have set the tyre
pressure correctly.
If an incorr ect tyre pressure is set, this in-
correct value will be monitored. 209en_d2.

Trailer towing
The detachable ball coupling is located in
the stowage
wellunder the boot floor.
You wil lfind details of installation dimen-
sions and loads in the "Technical data"
section.
Make a note of the key number in this
Owner's Manual, for example. This will
help you to obtain a replacement key from
a Mercedes-Benz Serv ice Ce ntre quickly,

tr ailer tow hitch is no longer required. P 31.10-2453-31 P 31.10-2454-31 G
Risk of accident The ball coup
ling is only correctly fitted once
the white ar eaon the ba llcoupling and the
gr ee nar ea on the han dwheelare aligned
and the key can be removed. Unless it is fit-
ted properly, the ball coupling could work
loose.
When the vehicl eis towing a trail er, the ball
coupling must be locked and the ke yre-
moved. Only then is it guaranteed that the
ball coupling issecure and cannot work
loose while the vehicle is being driven.
If the ball coupling can not be locked and the
key cannot be remove d, remove the ball
coupling and clean it ( =
pag e271). If you
still cannot fit (lock) the ball coupling after it
has been cleaned, rem ove it. Insuch cases,
the trailer tow hitch must not be used for
towing because its safety cannot be guaran-
teed. 209en

262 Operation
Trailer towing
iThe maxim umpermissible weights are given
in the vehicle documents and onthe type plates
of the trail erand the trailer tow hitch .The lowest
value given is decisive.
Th emax imum trailer drawb arno sewe ight forthe
trailer towbar on th eball neck is 75 kg. The draw-
bar no seweight must not, however, exceed that
specified on the type plates for th etrailer tow
hit ch and the trailer. If you couple a trailer, the driving charac-
terist
ics of your vehicle change.
The vehicl e/trailer combination:
! is heavier
! is restricted in its acceleration and
gradie nt-climbing capability
! has a longer stopping distance
! is more susceptible to gusting cross-
winds
! demands more sensitive steeri ng
Fuel consumption is higher when towing a
trailer.
Tips for driving when to wing a trailer:
! We recom mend utilising the maximum
per missible drawb arnoseweigh t,and
always at least 50 kg.
! The vehicle's payload must be reduced
to compensate for the drawbar nose-
weight so that thema ximum per missi-
ble rear axle load is not exceeded. Have the entire trailer tow hitch ch
ecked at
a qualifie dspecialist workshop which has
the necessary specia list knowledge and
tools to carry out the work required.
Mercedes-Benz recomme nds that youuse a
Mercedes-Benz Service Centre for this pur-
pose. In particular, work relevant to safety
or on safety-re lated systems must be car-
ried out at a qualified specialist workshop. Dr
iving tips G
Risk of accident Maximum care and atte
ntion iscalledfor
when coupling and decoupling a trailer.
Ma kesure that no-one is pre sent between
the trailer and the vehicle when the vehicle
is being reversed up to the trailer.
Do not uncouple a tr ailer with an overrun
brake when the brake is engaged. If you have coupled the trailer to the vehicle
incorr
ectly, there isa risk that the trailer
may break away.
Make sure that the following values have
been observed:
! Maximum permissi ble gross vehicle
weight
! Maximum permissible trailer drawbar
noseweight
! Maximum permissible trailer load
! Maximum permissible rearload on the
towing vehicle 209en_d2.boo Seite

Operation
Trailer towing
! You should not exceed a maximum
speed of 80 km /h, even incountries
where higher speeds are permitted.
! Avoid sudden braking. Instead, apply
the brake lightly at first, to allow the
trailer to overrun. Then increase the
braking for cerapidly.
! If the trailer starts to swing, reduce
your speed, do not attempt corrective
steering, and brake if necessary. On no
account should you attem pttodraw
the vehicle /trailer combination out by
increasing your speed.
! The gradient-climbing capabi lities from
a standstill are correct for sea level.
When driving in mountainous areas,
note that the power output of the en-
gine, and with itits gradient-climbing
capability from a standstill, decreases
with increasing altitude.
! Do not uncouple a trai ler with anoverrun
brake when the brake is engaged. The spring
action of the overrunning brake mechani sm
could damage the bumper. 6
Fold out the socket under the vehicle.
6 Remove the locked prot ective cap on
the handwheel.
6 Unlock the lock on the handwheel
usin g the key.
6 Hold the ball coupli ngfirmly. Lift the
handwheel off the ball coupling and
turn the handwheel clockwise until it
engages.
The red marking on the handwheel is
aligned with the white marking.
6 Remove the ball coupling by pulling
downwards.
6 Press the ball coupling cover into the
ball coupling recess.
Make sure that the cover is fitted se-
curely. Stowing the ball coupling

Stow the ball coupling in the ball
coupling well by the spare wheel. Removing the ball coupling
G
Risk of accident Do not carry the ball coupling unsecured in
the vehicle interior.
