Important safety notes
G
WARNING
When objects are unsecured or inadequately
secured, they can slip, turn over or be
thrown about, striking vehicle occupants.
This also applies to:
R luggage or loads
R seats which have been removed and are
being transported in the vehicle in an
exceptional case.
There is a risk of injury, particularly in the
event of a braking maneuver or abrupt
change in direction.
Always stow objects in such a way that they
cannot be tossed about. Before traveling,
secure objects, luggage or loads to prevent
them slipping or tipping over. If you remove
a seat, store it preferably outside the vehi-
cle. G
WARNING
As a result of improperly placed or unevenly
distributed loads, the center of gravity of the
load being transported may be too high or
too far back. This can significantly impair
handling as well as steering and braking
characteristics. There is a risk of an acci-
dent. Always make sure that the center of gravity
of the load is:
R between the axles
and
R as low as possible, near the rear axle. G
WARNING
When the permissible wheel loads, axle
loads and/or the maximum permissible
gross vehicle weight are exceeded, driving
safety is compromised. The handling as well
as steering and braking characteristics may
be significantly impaired. Overloaded tires
may overheat, causing them to burst. There
is a risk of an accident.
When transporting a load, always observe
the permissible wheel loads, axle loads and
the maximum permissible gross vehicle
weight for the vehicle (including occupants).
! If you are using a roof carrier, observe the
maximum roof load and maximum roof car-
rier load.
R Do not stack luggage or loads higher than
the backrests.
R Objects to be transported should preferably
be stowed in the cargo compartment.
R When transporting luggage, always use the
cargo tie-down rings for securing loads and
a cargo net, if installed.
R Use cargo tie-down rings and fasteners
which are suitable for the weight and size of
the load.
When using suitable load securing aids and tie
downs, always follow the manufacturer's oper-
ating instructions, in particular the notes on
discard criteria contained therein.
Load securing aids or tie downs must not be
used if:
R identification marks are missing or illegible
R there are yarn breakages, damage to bear-
ing seams or other signs of tearing
R there are signs of shearing, deformation,
pinching or other damage
R there is damage to clamping or connecting
elements
Load securing aids and tie downs in this condi-
tion are ready for discard and must be 242

Transporting loads

!
Do not use the lower sliding door guide
(carriage) as a step. Otherwise, you could
damage the paneling and/or the sliding
door mechanism.
! When cleaning your car, do not use:
R dry, coarse or hard cloths
R abrasive cleaning agents
R solvents
R cleaning agents containing solvents
Do not scrub.
Do not touch the surfaces and films with
hard objects, e.g. rings or ice scrapers. Oth-
erwise, you may scratch or damage the sur-
faces and films.
! Do not park your vehicle for a long period
of time directly after cleaning, particularly
after cleaning the wheel rim with wheel
cleaner. Wheel cleaner can lead to the
increased corrosion of the brake discs and
pads. Therefore, drive for a few minutes
after cleaning. By heating up the brakes, the
brake discs and pads dry. The vehicle can
then be parked for a long period of time. H
Environmental note
Only clean your vehicle at specially designed
wash bays. Dispose of empty containers and
used cleaning products in an environmen-
tally responsible manner. H
Environmental note
Dispose of empty packaging and cleaning
cloths in an environmentally responsible

Automatic car wash G
WARNING
Braking efficiency is reduced after washing
the vehicle. There is a risk of an accident. After the vehicle has been washed, brake
carefully while paying attention to the traffic
conditions until full braking power is
restored.
! Make sure that the automatic car wash is
suitable for the size of the vehicle.
Before washing the vehicle in an automatic
car wash, fold in the exterior mirrors and
remove any additional antennas. Otherwise,
the exterior mirror, antenna or the vehicle
itself could be damaged.
Make sure that the exterior mirrors are fully
folded out again and that any additional
antennas are re-installed when you leave the
automatic car wash.
! Make sure that:
R the side windows and roof are completely
closed
R the climate control blower is switched off
R the windshield wiper switch is in position

The vehicle may otherwise be damaged.
You can wash the vehicle in an automatic car
wash from the very start.
Wash off excess dirt before cleaning the vehi-
cle in an automatic car wash.
After putting the vehicle through an automatic
car wash, wipe off wax from:
R the windshield
R the windshield wiper blades
This will prevent smears and reduce wiping
noises caused by residue on the windshield.
R on vehicles with rear-end doors, from the
rear view camera lens in the top of the
license plate molding

vehicle in direct sunlight.
X Use a soft car sponge.
X Use a mild cleaning agent, e.g. a Mercedes-
Benz approved car shampoo.264
Care
Maintenance and care

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

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 safety notes G
WARNING
Risk of accident due to incorrect tire
pressure
Each tire, including the spare (if provided),
should be checked monthly when cold and
inflated to the inflation pressure recommen-
ded by the vehicle manufacturer on the vehi-
cle placard or tire inflation pressure label. (If
your vehicle has tires of a different size than
the size indicated on the vehicle placard or
the tire inflation pressure label, you should
determine the proper tire inflation pressure
for those tires.)
As an added safety feature, your vehicle has
been equipped with a tire pressure monitor-
ing system (TPMS) that illuminates a low tire
pressure telltale when one or more of your
tires is significantly under-inflated. Accord-
ingly, when the low tire pressure telltale illu-
minates, you should stop and check your
tires as soon as possible, and inflate them to
the proper pressure. Driving on a signifi-
cantly under-inflated tire causes the tire to
overheat and can lead to tire failure. Under-
inflation also reduces fuel efficiency and tire
tread life, and may affect the vehicle's han-
dling and stopping ability.
Please note that the TPMS is not a substi-
tute for proper tire maintenance, and it is
the driver's responsibility to maintain cor-
rect tire pressure, even if under-inflation has
not reached the level to trigger illumination
of the TPMS low tire pressure telltale.
Your vehicle has also been equipped with a
TPMS malfunction indicator to indicate
when the system is not operating properly.
The TPMS malfunction indicator is combined
with the low tire pressure telltale. When the
system detects a malfunction, the telltale
will flash for approximately one minute and
then remain continuously illuminated. This sequence will continue upon subsequent
vehicle start-ups as long as the malfunction
exists.
When the malfunction indicator is illumina-
ted, the system may not be able to detect or
signal low tire pressure as intended. TPMS
malfunctions may occur for a variety of rea-
sons, including the installation of replace-
ment or alternate tires or wheels on the
vehicle that prevent the TPMS from func-
tioning properly.
Always check the TPMS malfunction telltale
after replacing one or more tires or wheels
on your vehicle to ensure that the replace-
ment or alternate tires and wheels allow the
TPMS to continue to function properly.
It is the driver's responsibility to set the tire
pressure to the recommended cold tire pres-
sure suitable for the operating conditions
(Y page
282).
Note that the correct tire pressure for the cur-
rent operating conditions must first be pro-
gramed into the tire pressure monitor. If a sub-
stantial pressure loss occurs, the warning
threshold for the warning message is aligned
to the taught-in reference values. Restart the
tire pressure monitor after adjusting the cold
tire pressure ( Y page 288). The current pres-
sures are saved as new reference values. This
will ensure that a warning message will only
appear if the tire pressure drops significantly.
The tire pressure monitor does not warn you if
a tire pressure is incorrect. Observe the notes
on the recommended tire pressure
(Y page 282).
The tire pressure monitor is not able to warn
you of a sudden loss of pressure, e.g. following
penetration by a foreign object. In this event,
brake the vehicle until it comes to a standstill.
Avoid sudden steering movements.
The tire pressure monitor has a yellow h
warning lamp in the instrument cluster for indi-
cating pressure loss/malfunctions (USA) or
pressure loss (Canada). Depending on how the
warning lamp flashes or lights up, an underin-
flated tire or a malfunction in the tire pressure
monitor is displayed:

WARNING
Overloaded tires can overheat, causing a
blowout. Overloaded tires can also impair
the steering and driving characteristics and
lead to brake failure. There is a risk of acci-
dent.
Observe the load rating of the tires. The load
rating must be at least half of the GAWR of
your vehicle. Never overload the tires by
exceeding the maximum load. Example: Tire and Loading Information placard on
the B-pillar, driver's side
Two instruction labels on your vehicle show
the maximum possible load.
(1) Tire and Loading Information placard : is
on the
B-pillar on the driver's side. Tire

pants and the maximum permissible load
of the vehicle. It also contains details of
the tire sizes and corresponding pressures
for tires mounted at the factory.

150 lb passengers in your vehicle, the
amount of available cargo and luggage
load capacity is
650 lbs. (1400 Ò 750 (5 x

(5) Determine the combined weight of lug- gage and cargo being loaded on the vehi-
cle. That weight may not safely exceed the
available cargo and luggage load capacity
calculated in Step 4.
(6) If your vehicle will be towing a trailer, load from your trailer will be transferred to your vehicle. Consult this manual to determine
how this reduces the available cargo and
luggage load capacity of your vehicle.
The vehicle placard named in Step 1 is the Tire
and loading information placard for your vehi-
cle.
Please note that not all vehicles are approved
for trailer operation. Trailer operation is only
permitted when a trailer hitch is installed
(Y page

(Y page 315).Vehicle identification plate
Even if you have calculated the total load care-
fully, you should still make sure that the per-
missible gross weight and the gross axle
weight rating of your vehicle are not exceeded.
This data can be found on the vehicle identifi-
cation plate on the B-pillar of your vehicle
(Y page

304).
Gross Vehicle Weight Rating (GVWR): the
gross weight of the vehicle, all occupants, load
and trailer load/trailer tongue load (if applica-
ble) must not exceed the permissible gross
vehicle weight.
Gross Axle Weight Rating (GAWR): the maxi-
mum permissible load that can be carried by
one axle (front or rear axle).
To ensure that your vehicle does not exceed
the maximum permissible values (gross vehi-
cle weight and maximum gross axle weight rat-
ing), have your loaded vehicle (including driver,
occupants, load, and full trailer load if applica-
ble) weighed on a suitable vehicle weigh-
bridge. Trailer load/trailer tongue load
The trailer load/trailer tongue load affects the
gross weight of the vehicle. If a trailer is
attached, the trailer load/trailer tongue load is
included in the load along with occupants and
luggage. The trailer load/trailer tongue load is
usually approximately

10% of the gross weight
of the trailer and its load. What you should know about wheels
