Noise or unusual handling characteristics
While driving, pay attention tovibrations, noises
and unusual handling characteristics, e.g. pulling
to one side. This may indicate that the wheels or
tires are damaged. If you suspect that a tire is
defective, reduce your speed immediatel y.Stop
th eve hicle as soon as possible tocheck the
wheels and tires for dama ge. Hidden tire dam‐
age could also be causing the unusual handling
ch aracteristics. If youfind no signs of damage,
ha ve the tires and wheels checked at a qualified
specialist workshop.
Re gular checking of wheels and tires
&
WARNING Risk of accident from dam‐
aged tires
Dama ged tires can cause tire pressure loss.
As a result, you could lose cont rol of your
ve hicle.
#Check the tires regularly for signs of
dama geand replace any damaged tires
immediatel y.
&
WARNING Risk of aquaplaning due to
insuf ficient tire tread
Insuff icient tire tread will result in reduced
tire grip. The tire tread is no longer able to
dissipate water.
This means that in heavy rain or slush the
ri sk of hydroplaning is increased, in particu‐
lar if vehicle speed is not adap tedto suit the
conditions.
If th e tire pressure is too high or too lo w,
tires may exhibit dif fere nt le vels of wear at
dif fere nt locations on the tire conta ct sur‐
fa ce.
#Thus, you should regularly check the
tread de pth and the condition of the tire
conta ct surf ace across the entire width
of all tires.
Minimum tread dep thfor:
RSummer tires: âin (3 mm)
RM+S tires: ãin (4 mm)
#For saf etyre asons, replace the tires
before the legally prescribed limit for
th e minimum tread dep thisreached.
Car ryout thefo llowing checks on all wheels reg‐
ularly, at least once a month or as requ ired, e.g.
prior toa long journey or driving off- road:
RCheck the tire pressure (→page 339).
RVisual check of wheels and tires for dama ge.
RCheck theva lve caps.
The valves must be pr otected against mois‐
ture and dirt bytheva lve caps appr oved
especially foryo ur vehicle byMercedes-Benz.
RVisual check of the tread dep thand the tire
conta ct surf ace across the entire width.
The minimum tread dep thfor summer tires is
â in (3 mm) and for winter tires ãin
(4 mm).

Six marks1 show where the bar indicators
(ar row ) are integrated into the tire tread. They
are visible once a tread dep thof appr oximately
á in (1.6 mm) has been reached.
Note s on snow chains
&
WARNING Risk of accident due toincor‐
re ct mounting of snow chains
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
th e tires.
#Ne ver mount snow chains on the front
wheels.
#Only mount snow chains on there ar
wheels in pairs.
* NO
TEDama getothe wheel trim from
mounted snow chains
If snow ch ains are mounte dto steel wheels,
th e wheel trims can be damaged.
#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 an authorized
Mercedes-Benz Center.
RFo r saf etyre asons, only use snow ch ainsthat
ha ve been specifically appr oved foryo ur
ve hicle byMercedes-Benz, or snow chains
with the same quality standard.
RIf snow ch ains are moun ted, the maximum
permissible speed is 30 mph (50 km/h).
RVehicles with Parking Pilo t:Do no t use

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.
Wheels and tires 339

RThe tires maywearexc 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 handling characteristics and
th us dr iving saf ety, e.g. due to hydroplaning.
&
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
burs t because 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

&WARNING Risk of accident caused by
re peated drop in tire pressure
If th e tire pressure drops repeatedl y,the
wheel, valve or tire may be damaged.
Insuf ficient tire pressure can cause the tires
to bur st.
#Inspect the tire for signs of fore ign
objects.
#Check whe ther the wheel or valve has a
leak.
#If yo u are unab leto rectify the damage,
conta ct aqualified specialist workshop.
Yo u can find information on tire pressure forth e
ve hicle's factor y-ins talled tires on thefo llowing
labels:
RTi re and Loading Info rmation placard on the
B‑pillar of your vehicle (→page 345).
RTire pressure table on the inside of the fuel
fi ller flap (→page 341).
Observ eth e maximum tire pressure
(
→page 352). Use a suitable pressure
gauge tocheck the tire
pressure. The outer appearance of a tire does
not permit any reliable conclusion about the tire
pressure.
Ve hicles with a tire pressure monitoring sys‐
te m: You can also check the tire pressure using
th e on-board computer.
Only cor rect tire pressure when the tires are
cold. Conditions for cold tires:
RThe vehicle has been par ked with the tires
out of direct sunlight for at least th ree hours.
RThe vehicle has tr aveled less than 1 mile
(1.6 km).
A rise in the tire temp erature of 18°F (10 °C)
increases the tire pressure byappr ox.10 kPa
(0.1 bar/1.5 psi). Take this into account when
ch ecking the tire pressure of warm tires.
The tire pressure re commendedfor increased
load/speed in the tire pressure table can af fect
th eride comfort.
&
WARNING Risk of accident from unsuita‐
ble accessori es onthe tire valves
If yo u mount unsuitable accessories onto tire
va lves, the tire valves may be overloaded and
malfunction, which can cause tire pressure
loss. Tire pressure monitoring sy stems for
re trofitting will cause the tire valve toremain
open. This can also result in tire pressure
loss.
#Only scr ewstandard valve caps or valve
caps specifically appr ovedby
Mercedes-Benz foryo ur vehicle onto
th e tire valve.

The tire pressuretable sho ws there commended
tire pressure for all tires app rove dfo rth is vehi‐
cle. The recommended tire pressures apply to
cold tires under various operating conditions, i.e.
loading and/or speed of theve hicle.
If one or more tire sizes precede a tire pressure,
th e tire pressure information following is only
va lid forth ose tire sizes.
The load conditions "partially laden" and "fully
laden" are defined in theta ble for dif fere nt num‐
be rs of passengers and amounts of luggage. The
actual number of seats may dif fer from this.
Some tire pressure tables only show therim
diame ter ins tead of the comple tetire size, e.g.
R18 . The rim diame ter is part of the tire size and
can be found on the tire side wall (

#Re ad the tire pressure.
#Ifth e tire pressure is lo werth an there com‐
