WARNING Risk ofexplosion during
ch arging process and starting assis tance
During thech arging process and starting
assis tance, the battery may release an explo‐
sive gas mixture.
#Av oid fire , open flames, creating spar ks
and smoking.
#Make sure that there is suf ficient venti‐
lation du ring thech arging process and
during starting assis tance.
#Do not lean over a batter y.
Ifth e indicator/warning lamps in the instrument
clus ter do not light up at low temp eratures, it is
ve ry likely that the dischar ged battery has fro‐
zen.
& WARNING Risk ofexplosion from a fro‐
zen battery
A dischar ged battery may freeze at temp era‐
tures slightly abo veor below freezing point.
During starting assis tance or battery charg‐
ing, batte rygas may be released.
#Alw aysth aw a frozen batte ryout firs t

If yo u ha vemounted snow chains tothe front
wheels, the snow chains may drag against
th eve hicle body or chassis components.
This could cause damage totheve hicle or

#Re mo vethe wheel trims of steel wheels
before mounting snow chains.
RSn ow chains are only pe rmissible for cer tain
wheel/tire combinations. You can obtain information about
this from a Mercedes-Benz
service cen ter.
RFo r saf etyre asons, only use snowchains that
ha ve been specifically appr ovedfo ryo ur

with the same quality standard.
RIf snow chains are fitted, the maximum per‐
missible speed is 30 mph (50 km/h).

Tire pressure
Note s on tire pressure
&
WARNING Risk of accident due toinsuf‐
fi cient or excessive tire pressure
Underinfla ted or overinfla ted tires pose the
fo llowing risks:
RThe tires may bur st, especially as the
load and vehicle speed increase.
RThe tires may wearexc essively and/or
une venly, which may greatlyimpair tire
traction.
RThe driving characteristics, as well as
st eering and braking, may be greatly
impaired.
#Comply with there commended tire
pressure and check the tire pressure of
all tires including the spare wheel regu‐
larly:
Rat least once a month
Rwhen the load changes
Rbefore embarking on a longe r journey
Rif operating conditionschange, e.g. off-
ro ad driving
#Ad just the tire pressure as necessar y.
Driving withtire pressure that is too high or too
low can:
RSho rten the service life of the tires.
RCause increased tire damage.
RAd versely af fect driving characteristics and
th us dr iving saf ety, e.g. due toaquaplaning.
&
WARNING Risk of an accident due to
insuf ficient tire pressure
Ti re s with pressure that is too low can over‐
heat and bur stas a result.
In addition, they also suf fer from excessive
and/or ir regular wear, which can significantly
impair the braking properties and the han‐
dling characteristics.
#Av oid excessively low tire pressures in
all the tires, including the spare wheel.
Tire pressure which is too low can cause:
RTire defects as a result of overheating
RImpaired handling characteristics
RIrre gular wear
RIncreased fuel consum ption
&
WARNING Risk of accident from exces‐
sive tire pressure
Ti re s with excessively high pressure can
bur stbecause they are damaged more easily
by highw ayfill, pot holes etc.
In addition, they also suf fer from ir regular
we ar, which can significantly impair the brak‐
ing properties and the handling characteris‐
tics.
#Av oid excessively high tire pressures in
all the tires, including the spare wheel.
Excessively high tire pressure can result in:
RIncreased braking dis tance
RImpaired handling characteristics
RIrre gular wear
Wheels and tires 363

The system checks the tire pressure and the tire
te mp erature of the tires ins talled on theve hicle
by means of a tire pressure sensor.
New tire pressure sensors, e.g. in winter tires,
are automatically taught-in during thefirs t jour‐
ney they are used.
If th ere is a subs tantial pressure loss or if the
tire temp erature is excessive, a warning will be
given:
Rvia display messages (→page 429)
Rvia theh warning lamp in the instrument
clus ter (→page 462)
It is the driver's responsibility toset the tire
pressure tothere commended cold tire pressure
suitable forth e operating situation. Set the tire
pressure for cold tires using a tire pressure
ga uge. Notethat the cor rect tire pressure forth e
cur rent operating situation must firs t be taught-
in to the tire pressure monitoring sy stem.
In most cases, the tire pressure monitoring sys‐
te m will auto matically update the new refere nce
va lues af teryo u ha vechanged the tire pressure.
Yo u can, ho wever,also update there fere nce val‐ ues
byrestarting the tire pressure monitoring
sy stem manually (

Tr action grade
&
DANG ER Risk of accident due toinade‐
qu ate traction
The traction grade assigned tothis tire is
based on stra ight-ahead braking traction
te sts, and does not include either accelera‐

The traction grades – from highest tolowest –
are AA, A,B and C. Those grades represent the
tire's ability tostop on wet pa vement as meas‐
ured under controlled conditions on specified
go vernment test sur faces made of asphalt and
concr ete.
Te mp erature grade
&
WARNING Risk of accident from tire
ove rheating and tire failure
The temp erature grade forth is tire is es tab‐
lished for a tire that is proper ly inflated and
not overloaded. Excessive speed, underinfla‐
tion, or excessive loading, either separately
or in combination, can cause excessive heat
build-up and possible tire failure.
#Obser vethere commended tire pres‐
sure s and regularly check the tire pres‐
sure of all tires including the spare
wheel.
#Ad just the tire pressure as necessar y.
Thetemp erature grades are A (the highest), B
and C. They represent the tire's resis tance tothe
ge neration of heat and its ability todissipate
heat when tested under controlled conditions on
a specified indoor laboratory test wheel. Sus‐
ta ined high temp erature can cause the material
of the tire todegenerate and reduce tire life, and
exc essive temp erature can lead tosudden tire
fa ilure. Grade C cor responds toa le vel of per‐
fo rm ance which all passenger car tires must
meet under therequ irements of the US Depart‐
ment of Transpor tation.

US tire regulations stipulate that eve rytire man‐
