tor lever
X
Thoroughly wipe with a damp cloth.
X Vehicles with leather upholstery: after
cleaning, use leather care agents that have
been recommended and approved by
Mercedes-Benz.
Cleaning the trim elements !
Do not use solvent-based cleaning agents
such as tar remover, wheel cleaners, pol-
ishes or waxes. There is otherwise a risk of
damaging the surface.
X Wipe the trim elements with a damp, lint-
free cloth, e.g. a microfiber cloth.
X Heavy soiling: use care products and
cleaning agents recommended and
approved by Mercedes-Benz.
Cleaning the seat covers !
Do not use microfiber cloths to clean gen-
uine leather or artificial leather covers. If
used often, a microfiber cloth can damage
the cover.
! Clean:
R artificial leather covers with a cloth mois-
tened with a solution containing 1% deter-
gent, e.g. dish washing liquid.
R cloth covers with a microfiber cloth mois-
tened with a solution containing 1% deter-
gent, e.g. dish washing liquid. Wipe entire
seat sections carefully to avoid leaving
visible lines. Leave the seat to dry after-
wards. Cleaning results depend on the
type of dirt and how long it has been
there.
R genuine leather covers carefully with a
damp cloth, then wipe the covers down
with a dry cloth. Make sure that the
leather does not become soaked. Other-
wise, the leather could become rough or
cracked. Only use leather care agents
that have been tested and approved by
Mercedes-Benz. You can obtain these
from a qualified specialist workshop.
i Please keep in mind that:
R leather covers are a natural product and,
as such, are subject to a natural aging process. Leather may react differently,
e.g. increased wrinkling, to certain envi-
ronmental influences (such as high
humidity or intense heat).
R regular care is essential to make sure that
the appearance and comfort of the covers
are retained over time.
To clean genuine leather covers: X Remove any dust, crumbs etc. If necessary,
carefully vacuum-clean the seat covers.
X Carefully wipe the leather seat covers with a
damp cloth.
X Wipe over again with a dry cloth.
Make sure that the leather does not become
soaked, especially perforated parts.
X Then treat the leather seats with a leather
care foam.
Only use leather care agents that have been
tested and approved by Mercedes-Benz.
Observe the manufacturer's instructions.
Cleaning the seat belts G
WARNING
Seat belts can become severely weakened if
bleached or dyed. This could cause the seat
belts to tear or fail, for instance, in the event
of an accident. This poses an increased risk
of injury or fatal injury.
Never bleach or dye the seat belts.
! Do not clean the seat belts using chemical
cleaning agents. Do not dry the seat belts
by heating at temperatures above
176 ‡
(80 †) or in direct sunlight.
Remove any stains or dirt immediately. This
will avoid residue or damage. X Use clean, lukewarm water and soap solu-
tion.

Useful information
This Operator's Manual describes all models
as well as standard and optional equipment of
your vehicle that were available at the time of
going to print. Country-specific variations are
possible. Note that your vehicle may not be
equipped with all of the described functions.
This also applies to systems and functions rel-
evant to safety.
Read the information on qualified specialist
workshops (Y page
32).Important safety notes
G
Warning
A flat tire severely impairs the driving, steer-
ing and braking characteristics of the vehi-
cle. There is a risk of an accident.
do not drive with a flat tire. Immediately
replace the flat tire with your spare wheel,
or consult a qualified specialist workshop. G
WARNING
If you install wheels and tires with incorrect
dimensions, the service brake or wheel sus-
pension components may be damaged.
There is a risk of an accident.
Always replace wheels and tires with ones
that comply with the specifications of the
original part.
When replacing wheels, pay attention to the:
R Designation
R Model
When replacing tires, pay attention to the:
R Designation
R Manufacturer
R Model
Accessories that are not approved for your
vehicle by Mercedes-Benz or are not being
used correctly can impair operating safety. Before purchasing and using non-approved
accessories, visit a qualified specialist work-
shop and inquire about the following points:
R
suitability
R legal stipulations
R factory recommendations
Information on the dimensions and types of
wheels and tires for your vehicle can be found
under "Wheel and tire combinations"
( Y page
301).
Information on your vehicle's tire pressures
can be found in the following locations:
R in the Tire and Loading Information placard
on the B-pillar, driver's side
R in the tire pressure table inside the fuel filler
flap ( Y page 282)
R under "Tire pressure tables" (Y page 289)
R under "Tire pressure" (Y page 282)
Modifications to the brake system or wheels
are not permitted. The use of spacers or brake
dust shields is not permitted. This invalidates
the general operating permit for the vehicle.
Further information on wheels and tires can be
obtained at any qualified specialist workshop. Operation
Information for a journey
If the vehicle is heavily laden, check the tire
pressures, and correct them, if necessary
( Y page

282).
While driving, pay attention to vibrations,
noises and unusual handling characteristics,
e.g. pulling to one side. This may indicate that
the wheels or tires are damaged. If you sus-
pect that a tire is defective, reduce your speed
immediately. Stop the vehicle as soon as pos-
sible to check the wheels and tires for dam-
age. Hidden tire damage could also be causing
the unusual handling characteristics. If you
find no signs of damage, have the tires and
wheels checked at a qualified specialist work-
shop.
When parking your vehicle, make sure that the
tires do not get deformed by the curb or other
obstacles. If it is necessary to drive over curbs,
speed humps or similar elevations, try to do so
slowly and not at a sharp angle. Otherwise, the
tires, particularly the sidewalls, can get dam-
aged. 278
Operation
Wheels and tires

Regular wheel and tire checks
G
WARNING
Damaged tires can cause tire inflation pres-
sure loss. As a result, you could lose control
of your vehicle. There is a risk of accident.
Check the tires regularly for signs of dam-
age and replace any damaged tires immedi-
ately.
Check the wheels and tires of your vehicle for
damage regularly, i.e. at least every two
weeks, as well as after driving off-road or on
rough roads. Damaged wheels can cause a
loss of tire pressure. Pay particular attention
to damage such as:
R cuts in the tires
R punctures
R tears in the tires
R bulges on tires
R deformation or severe corrosion on wheels
Regularly check the tire tread depth and the
condition of the tire tread across the whole
width of all the tires
(Y page 279). If neces-
sary, turn the front wheels to full lock in order
to inspect the inner side of the tire surface.
All wheels must have a valve cap to protect
the valve against dirt and moisture. Do not
install anything onto the valve other than the
standard valve cap or other valve caps
approved for your vehicle by dealers listed on
the inside of the front cover. Do not install any
other valve caps or systems, e.g. tire pressure
monitor systems.
Regularly check the pressure of all the tires,
particularly prior to long trips. Adjust the tire
pressure if necessary (Y page 282).
The service life of tires depends on various
factors, including the following:
R Driving style
R Tire pressure
R Mileage Tire tread
G
WARNING
If there is insufficient tire tread, the tire trac-
tion decreases. The tire tread is no longer
able to dissipate water. This increases the risk of hydroplaning when the road surface
is wet, particularly when the vehicle's speed
is not adapted to the road conditions. There
is a risk of an accident.
When the tire pressure is too high or too
low, tires may wear differently at different
points on the tire tread. Therefore, regularly
check the tire tread depth and the condition
of the tread across the whole width of all
tires.
Minimum tire tread depth on:
R Summer tires: â in (3 mm

)
R M+S tires: ã in (4 mm)
For safety reasons, have the tires replaced
before they reach the legally prescribed min-
imum tire tread depth. Marker : shows the location where the bar
indicator (arrow) for tread wear is integrated
into the tire tread.
Tread wear indicators (TWIs) are required by
law. Six indicators are positioned over the tire
tread. They are visible once the tire tread
depth is approximately á in (1.6 mm

). If this
is the case, the tire is so worn that it must be
replaced. Selecting, mounting and replacing
tires
R Only mount tires and wheels of the same
type and make.
R Only use wheels with tire sizes approved by
Mercedes-Benz.
R Only mount tires of the correct size onto the
wheels. Operation
279Wheels and tires Z

R
Break in new tires at moderate speeds for
the first
65 miles (100 km).
R Do not drive with tires which have too little
tread depth, as this significantly reduces the
traction on wet roads (hydroplaning).
R Replace the tires after six years at the lat-
est, regardless of wear. This also applies to
the spare wheel. Operation in winter
General notes
Have your vehicle winterized at a qualified spe-
cialist workshop at the onset of winter.
Only use wheels with tire sizes approved for
Mercedes-Benz.
Prior to the onset of winter, ensure that snow
chains are stowed in the vehicle
(Y page

281). Snow chains cannot be moun-
ted on all wheel/tire combinations. Observe
the restrictions on the use of snow chains
under "Wheel/tire combinations"
(Y page 302).
Also observe the notes in the "Changing a
wheel" section ( Y page 297).Driving with summer tires
At temperatures below 45 ‡
(+7 †), summer
tires lose elasticity and therefore traction and
braking power. Change the tires on your vehi-
cle to M+S tires. Using summer tires at very
cold temperatures could cause tears to form,
thereby damaging the tires permanently.
Mercedes-Benz cannot accept responsibility
for this type of damage. M+S tires
G
WARNING
Wheel and tire dimensions as well as the
type of tire can vary between the spare
wheel and the wheel to be replaced. When
the spare wheel is mounted, driving charac-
teristics may be severely affected. There is a
risk of an accident. In order to reduce risks:
R you should therefore adapt your driving
style and drive carefully.
R never mount more than one spare wheel
that differs from the wheel to be replaced.
R only use a spare wheel that differs from
the wheel to be replaced for a short time.
R have a spare wheel that differs from the
wheel that has been changed replaced at
the nearest qualified specialist workshop.
You must observe the correct wheel and
tire dimensions as well as the wheel type. G
WARNING
M+S tires with a tire tread depth of less than
ã in
(4 mm) are not suitable for use in win-
ter and do not provide sufficient traction.
There is a risk of an accident.
M+S tires with a tread depth of less than ã
in (4 mm) must be replaced immediately.
Use winter tires or all-season tires at tempera-
tures below 45 ‡ (+7 †). Both types of tire
are identified by the M+S marking.
Only winter tires bearing the i snowflake
symbol in addition to the M+S marking provide
the best possible grip in wintry road condi-
tions.
Only these tires will allow driving safety sys-
tems such as ABS and ESP ®
to function opti-
mally in winter. These tires have been devel-
oped specifically for driving in snow.
For safe driving, use M+S tires of the same
make and tread pattern on all wheels.
Always observe the maximum permissible
speed specified for the M+S tires you have
mounted.
If you mount M+S tires that have a lower maxi-
mum permissible speed than the maximum
design speed of the vehicle, affix a corre-
sponding warning label in the driver's field of
vision. You can obtain this at a qualified spe-
cialist workshop.
Once you have mounted the winter tires:
X Check the tire pressure (Y page
282).
X Restart the tire pressure monitor
(Y page

288).280

Snow chains
G
WARNING
If snow chains are installed to the front
wheels, they may drag against the vehicle
body or chassis components. This could
cause damage to the vehicle or the tires.
There is a risk of an accident.
To avoid hazardous situations:
R never install snow chains to the front
wheels
R always install snow chains in pairs to the
rear wheels. G
WARNING
If you drive too fast with snow chains moun-
ted, they may snap. As a result, you could
injure others and damage the vehicle. There
is a risk of an accident.
Observe the maximum permissible speed for
operation with snow chains.
When driving with snow chains installed, do
not exceed the maximum permissible speed of
30 mph (50 km/h
). Observe the country-spe-
cific laws and regulations for operation with
snow chains.
! Check the snow chains for damage before
mounting them. Damaged or worn snow
chains may snap and damage the following
components:
R wheel
R wheel housing
R wheel suspension
For this reason, you must use only snow
chains that are free of defects. Observe the
manufacturer's mounting instructions.
! Vehicles with steel wheels:
if you mount
snow chains on steel wheels, you may dam-
age the hub caps. Remove the hub caps
from the relevant wheels before mounting
the snow chains.
Snow chains increase traction on roads in win-
try conditions.
For safety reasons, Mercedes-Benz recom-
mends that you only use snow chains or trac-
tion aids which have been approved for
Mercedes-Benz vehicles. The snow chains or traction aids must be of class U or meet the
SAE type U

specification.
Information about snow chains can be
obtained from any Mercedes-Benz Commercial
Van Center.
When mounting snow chains, please bear the
following points in mind:
R Snow chains cannot be mounted on all
wheel/tire combinations. When mounting
the snow chains, note the permissible tire
and snow chain dimensions. Observe the
restrictions on the use of snow chains under
"Wheel/tire combinations" (Y page 302).
R Mount snow chains only in pairs and only to
the rear wheels. Observe the manufacturer's
mounting instructions.
R Only use snow chains when the road is cov-
ered by a layer of snow. Remove the snow
chains as soon as possible when you come
to a road that is not snow-covered.
R The use of snow chains may be restricted by
local regulations. Observe the appropriate
regulations before mounting snow chains.
R When driving with snow chains installed, do
not exceed the maximum permissible speed
of 30 mph (50 km/h).
R Check the tension of the chains after a dis-
tance of approximately 0.5 miles (1.0 km)
and tighten the chains if required.
You may wish to deactivate ESP ®
when pulling
away with snow chains installed ( Y page 69).
This allows the wheels to spin in a controlled
manner, achieving an increased driving force
(cutting action). Operation in winter

Important safety notes G
WARNING
Tire valve that are not approved for your
vehicle by the distributor named on the
inside cover page may result in a loss of tire
pressure. This may affect road safety. There
is a risk of an accident.
Only use tire valve that are approved for
your vehicle by the distributor named on the
inside cover page. Always make sure you
have the correct tire valve type for the tires
on your vehicle.
! Do not screw additional weights (check
valves, etc.) onto the tire valves. The elec-
tronic components could thus be damaged.
i For safety reasons, Mercedes-Benz recom-
mends that you only use tire valves that
have been tested for use on your vehicle. Checking the tire pressure manually
In order to determine and adjust the tire pres-
sures, proceed as follows: X Remove the valve cap of the tire you wish to
check.
X Press the tire pressure gauge securely onto
the valve.
X Read the tire pressure and compare it with
the recommended value on the loading
information table or the tire pressure table
( Y page

282).
X If the tire pressure is too low, increase it to
the recommended value.
X If the tire pressure is too high, release air by
pressing down the metal pin in the valve.
Use the tip of a pen, for example. Then,
check the tire pressure again using the tire
pressure gauge.
X Screw the valve cap onto the valve.
X Repeat the steps for the other tires. Tire pressure monitor
General notes In vehicles with a tire pressure monitor sys-
tem, the vehicle's wheels have sensors instal-
led which monitor the tire pressure in all four
tires. The tire pressure monitor warns you if
the pressure drops in one or more of the tires.
The tire pressure monitor only functions if the
corresponding sensors are installed on all
wheels.

WARNING
Exceeding the stated tire load-bearing capa-
city and the approved maximum speed
could lead to tire damage or the tire burst-
ing. There is a risk of accident.
Therefore, only use tire types and sizes
approved for your vehicle model. Observe
the tire load rating and speed rating
required for your vehicle. :

Tire width: tire width : shows the nominal
tire width in millimeters.
Aspect ratio: aspect ratio ; is the size ratio
between the tire height and tire width and is
shown in percent. The aspect ratio is calcula-
ted by dividing the tire width by the tire height.
Tire code: tire code = specifies the tire type.
"R" represents radial tires. "D" represents
diagonal tires, "B" represents diagonal radial
tires.
Rim diameter: rim diameter ? is the diame-
ter of the bead seat, not the diameter of the rim flange. The rim diameter is specified in
inches (in).
Load-bearing index: load-bearing index
A is
a numerical code that specifies the maximum
load-bearing capacity of a tire.
Do not overload the tires by exceeding the
specified load limit. The maximum permissible
load can be found on the vehicle's Tire and
Loading Information placard on the B-pillar
on
the driver's side (Y page 289).
Example:
The load-bearing index 101 indicates a maxi-
mum load of 1819 lb (825 kg) for the tire. If
two load-bearing indices are specified, the first
number specifies the load-bearing capacity for
single tires, the second the load-bearing capa-
city for twin tires. For further information on
the maximum tire load in kilograms and
pounds, see (Y page 294). For further information on the load-bearing
index, see "Load index" (Y page 294).
Speed rating: speed rating B specifies the
approved maximum speed of the tire.
Regardless of the speed index always observe
