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
Operation in winter
Wheels and tires

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
Underinflated or overinflated tires pose the
following risks:
R the tires may burst, especially as the load
and vehicle speed increase.
R the tires may wear excessively and/or
unevenly, which may greatly impair tire
traction.
R the driving characteristics, as well as
steering and braking, may be greatly
impaired.
There is a risk of an accident.
Follow recommended tire inflation pressures
and check the pressure of all the tires
including the spare wheel:
R monthly, at least
R if the load changes
R before beginning a long journey
R under different operating conditions, e.g.
off-road driving
If necessary, correct the tire pressure.
The tire pressure monitor will not warn you of: R an incorrectly set tire pressure
R sudden loss of tire pressure, for example
caused through intrusion from a foreign
object G
WARNING
If you fit unsuitable accessories onto tire
valves, the tire valves may be overloaded
and malfunction, which can cause tire pres-
sure loss. Due to their design, retrofitted tire
pressure monitors keep the tire valve open.
This can also result in tire pressure loss.
There is a risk of an accident.
Only screw the standard valve cap or other
valve caps approved by Mercedes-Benz for
your vehicle onto the tire valve. !
The pressure difference between tires on
any one axle must be no greater than
10 kPa
(0.1 bar/1.5 psi).
i The specifications shown on the sample
Tire and Loading Information placard and
tire pressure table are examples. Tire pres-
sure data are vehicle-specific and may devi-
ate from the data illustrated here. The tire
pressure specifications that are valid for
your vehicle can be found on the Tire and
Loading Information placard and the tire
pressure table on the vehicle. H
Environmental note
Check the tire pressure regularly, at least
every
14 days.
General notes You will find information on tire pressure for
the vehicle's factory-mounted tires on the
plates described here.
The recommended tire pressure for various
operating conditions can be found on the Tire

(example: Cargo Van)
You will find the recommended tire pressure
for various operating conditions on the inside
of your vehicle's fuel filler flap
(Y page 137)
and under "Tire pressure table" (Y page 289).
If a tire size precedes a tire pressure, the fol-
lowing tire pressure information is only valid
for that tire size. Example: Cargo Van vehicle loads
Example: Passenger Van vehicle loads
:
Partially laden vehicle
; Fully laden vehicle
For the Passenger Van, the vehicle loads are
defined in the table as different numbers of
passengers and amounts of luggage. The
actual number of seats may vary – for more
information, please refer to the vehicle's regis-
tration documents.
The tire pressure value given for partly laden
vehicles are minimum values which offer you
good ride comfort. They are not for towing
trailers.
You can also use the tire pressure values for a
fully laden vehicle. These are always permitted
and admissible. However, in a partially laden
vehicle, the ride is not as comfortable and fuel
consumption is only minimally reduced. In
addition, wear is greater in the center of the
tire tread.
For towing trailers, the applicable value for the
rear tires is the maximum tire pressure value
stated in the table inside the fuel filler flap. Tire pressure

Important notes on tire pressure
G
WARNING
If the tire pressure drops repeatedly, the
wheel, valve or tire may be damaged. Tire
pressure that is too low may result in a tire
blow-out. There is a risk of an accident. R Check the tire for foreign objects.
R Check whether the wheel is losing air or
the valve is leaking.
If you are unable to rectify the damage, con-
tact a qualified specialist workshop.
Use a suitable pressure gauge to check the
tire pressure. The outer appearance of a tire
does not permit any reliable conclusion about
the tire pressure. On vehicles equipped with
the electronic tire pressure monitor, the tire
pressure can be checked using the on-board
computer.
The tire temperature and pressure increase
when the vehicle is in motion. This is depend-
ent on the driving speed and the load.
Therefore, you should only correct tire pres-
sure when the tires are cold.
The tires are cold: R if the vehicle has been parked for at least
three hours without direct sunlight on the
tires, and
R if the vehicle has not been driven further
than
1 mile (1.6 km)
Tire temperature changes depending on the
ambient temperature, driving speed and tire
load. If the tire temperature changes by 18 ‡
(10 †), the tire pressure changes by approx-
imately 10 kPa (0.1 bar/1.5 psi). Take this into
account when checking the pressure of warm
tires. Only correct the tire pressure if it is too
low for the current operating conditions. If you
check the tire pressure when the tires are
warm, it results in a higher value than when
the tires are cold. This is normal. Do not under
any circumstances release the air in order to
adjust the pressure to the prescribed value for
cold tires. The tire pressure would otherwise
be too low.
Observe the recommended tire pressure for
cold tires on the tire pressure table in the fuel
filler flap. Driving with tire pressure that is too high or
too low can:
R shorten the service life of the tires
R cause increased tire damage
R have a negative effect on handling charac-
teristics and thus the driving safety (e.g.
hydroplaning) Underinflated or overinflated tires
Underinflated tires: G
WARNING
Tires with pressure that is too low can over-
heat and burst as a consequence. In addi-
tion, they also suffer from excessive and/or
irregular wear, which can severely impair the
braking properties and the driving character-
istics. There is a risk of an accident.
Avoid tire pressures that are too low in all
the tires, including the spare wheel.
Underinflated tires can:
R fail from being overheated
R adversely affect handling
R wear excessively and/or unevenly
R have an adverse effect on fuel consumption
Overinflated tires G
WARNING
Tires with excessively high pressure can
burst because they are damaged more eas-
ily by road debris, potholes etc. In addition,
they also suffer from irregular wear, which
can severely impair the braking properties
and the driving characteristics. There is a
risk of an accident.
Avoid tire pressures that are too high in all
the tires, including the spare wheel.
Overinflated tires can:
R increase the braking distance
R adversely affect handling
R wear excessively and/or unevenly
R adversely affect ride comfort
R be more susceptible to damage284
