4 Protection
ofthe environment
Introduction Protection of the environment
H
Enviro nment alno te Dai
mlerChrysl er's declared policy is one of
comprehensive environmental protection.
The objectives are for the natural resources
whi chform the basis of our existen ceon this
pl anet to beused sparingly an din a manner
whi chtakes the requirements of both nature
an d hu manity in to account.
Yo ut oo can make a contribution towards
protecting the environment by operating
your vehicle in an environmentally-responsi-
ble manner.
Fue lconsumption and the rate of en gine,
tra nsmission, brake and tyre wear dep end
on the following:
! the operating conditions of your vehicle
! your driving style
Yo u can influence bothofthese condition s. Therefore, bear the following in
mind:
Operating conditions
! Avoid drivi ngshort dista nces as this
inc reases fuel consumption.
! Make sure that tyre pressures are
alway scorrect.
! Do not carry any unnecessary we ight.
! Keep an eyeonthe vehic le's fuel con-
sumption.
! Remove roof racks once you no longer
need them.
! A regularly serviced vehicle will contrib-
ute to environmental protection. You
should there fore adhere to th eservice
intervals.
! Always have service work carried out at
a qualified specialist workshop, e.g. at a
Mercedes-Benz Service Centre. Style of driving:
!
Do not depress the accelerator pedal
when starting the engine.
! Do not warm up the engine with the
vehicle st ationary.
! Drive carefu lly and maintain sufficient
dista nce from the vehic lein front.
! Avoid frequent ,powerful acce leratio n.
! Change gear ingood timeand use each
gear only up to 2
/ 3 of its maximum
engine speed.
! Switch off the engine in stationary traf-
fic.

Operation
Tyres and wheels
! For safe tyreasons, Mercedes-Benz recom-
mend syou only use tyre swhich have bee nspe-
cially approved for yourvehicle byMercede s-
Benz. These tyres are specially suite dto your
vehicle's control systems, such as ABS or ESP.
Mercedes-Benz can accept no responsibility for
damage resulting from using tyr esother than
those approved for your ve hicle .Information
about tyr esmay be obtained from any
Mercedes-Benz Serv ice Centre.
If you use tyres other tha nthose which have
been test edand recommended for Mercedes-
Benz, cha racteristics suc hashandling, noi se
levels and fuel consum ption may beadversely
affected. Moreo ver, dimensional variations and
different tyre defo rmation characteristics when
running under load could cause the tyre to make
contact with thebo dywork or axle components.
The consequen cecould be damage to the tyre or
to the vehicl e. !
Retreaded tyres are neither tested nor
re commended for Mercedes-Benz vehicle s,as
previous damage cannot always be det ectedon
re treaded tyres. As aresul t, Me rced es-Benz
ca nnot guarantee driving safety.
Modification work on the brake system
and wheels is not permi tted, nor is the use
of spacer plates or brake dust shields. Any
such modifications invalidate the vehicle's
genera loperating permit. !
Only fit tyres and wheels of the same
type and make.
! Onlyfit ty res of the correct size to the
wh eels.
! Run in new tyres at moderate speeds
forthe first 10 0km.
! Check the tyres and wheels for damage
regularly, at least every 14 days. Dam-
aged rims could cause a loss of tyre
pre ssur ean d damag eto th e wheels.
! Check the tyre pressures regularly and
correct them if necessary – see Fuel
fil ler cap (
=pa ge 241).
! Do not continue to use tyres with se-
vere lyworn treads. Tyre grip dec reases
rapidly on wet roads below a tread
depth of 3 mm. Tyres and wheels

Risk of accident Only use wheels of the dimensions
stated in
the vehicle registration documents. If other
wheel sizes are used:
! the wheel brakes or chassis compo-
nents could be damaged

250 Operation
Tyres and wheels
!
Fit single new tyres on the front wheels
first if tyres of the same size are fitted
on the front and rear wheels.
! Remove the rust from corr oded steel
wh eels and repaint them.
! Replace the tyres at least every
6years, irrespective of their degree
of wear.
! Adjust the tyre pressures if the vehicle
is laden – see Fuel filler cap
(= page 241).
! Storetyres ina cool, dry place, preferably in
the dark. Protect the tyres from oil, grease,
petrol and diesel.
Do not clean your wheels with acidic wheel
cl eaners since these could corrode the wheel
bolts. Tyres with a specified direction of rotation
offer additional benefi
ts,e.g. with regard
to aquaplaning. These benefits are only
available to you ifthe correct direction of
rotation isobserved.
An arrow on the sidewa llof the tyre indi-
cates its correct direction of rotation.
i A spare wheel* may also be fi tted against
th edirection of rotatio n. The MO
Extended run-flat system allows
you to cont inue driving your vehicle, even
if there is a complete loss of air in one or
more tyres.
You can only use the MO Extendedrun-flat
system in conjunction with the tyre pres-
sure loss warning system.
For notes about driving in the event of a
flat tyre, see the Practical advice section

Operation
Tyres and wheels
Only correct the tyre pressures when the
tyres are cold.
The pressures of warm tyres should only
be corrected if the yare too low for the cur-
rent operat ing condi tions. Warm tyres al-
ways have higher tyre pressures than cold
tyres.
You will find a table oftyre pressures for
va rious operating conditions on the inside
of the veh icle's fuel filler flap. i
Tyre pressure values given for low loads are
mi nimum value swhich offer you good ride com-
fort charact eristics.
You can, however, also usethe value sfor higher
lo ads. These are permissible and do not adverse-
ly aff ect the running of thevehicle. However, ride
co mfort will be impaired to som edegree.
Als ocheck thet yre pressure of thespare
wheel*.
Ty re pressure changes by approximately
0. 1b ar for every 10 °C change in ambient
temperature. If you measure the tyre pres-
sures indoors where the temperature dif-
fers from the outside temperature, you will
have to correct the measured values ac-
cor dingly.
When the vehicle isdriven, the tyre tem-
perature, and wi thit the tyre pressure, in-
crease as a function of the road speed and
the load on the tyres. During the journey, the tyre pressure loss
warning system monitors the set tyre pres-
sure by comparing the speed of rotation of
the
wheels. This enables the system to de-
tect whether there has been a significant
drop in tyre pressure in one of the tyres. If
the rotation speed of a wheel changes be-
cause of a drop in tyre pressure, a corre-
sponding warning message appears in the
multi -function display. Tyre pr

252 Operation
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.

Practical advice
Flat tyre
6 If you have obtained a pressure of
1.8 bar, press the switch on the elec-
tric air pum pto 0.
The electric air pump isswitched off.
6 Discon nect the electric air pump.
6 Pull away immediately.
This allows the TIRE FIT sealant to dis-
tribute throughout the tyre.
6 Stop after about ten minutes and
chec kthe tyre pressure with the elec-
tric air pum p.
6If the tyre press ure is at least 1.3 bar,
correct it (see fuel filler flap for values).
To increase the tyre pressure:
6 switch on the electric air pump
To decrease the tyre pressure: 6 open the pr essure release screw on
pressure gauge 9 6
Drive to the nearest workshop and
have the tyre rep lace d.
6 Have the TIREFIT kit replaced as soon
as possible at a qua lified speci alist
wo rkshop, e.g. a Mercedes-Benz Serv-
ice Centre.
6 Have the TIRE FIT kit replaced every
four years at a quali fied specialist
wo rkshop, e.g. a Mercedes-Benz Serv-
ice Centre. G
Risk of accident If the pressure has fa
llen below1.3 bar, the
tyre is too badly damaged.
Do not dr ive any further. Consul ta qualified
specialist workshop which has the neces-
sary specialist knowledge and tools to carry
out the work required. Mercede s-Benz rec-
omm ends that you use a Merc edes-Benz
Service Centre for this purpose. In particu-
la r, work relevant to safety or on safety-
related systems must be carried out at a
qu alified specialist workshop. G
Risk of accident Do not
exceed the maximum speed of
80 km /h.
