Useful information
i This Owner's Manual describes all models
and all standard and optional equipment
available to your vehicle at the time of pub-
lication of the Owner's Manual. Country-
specific deviations are possible. Please
note that your vehicle may not be equipped
with all features described. This also
applies to safety-relevan tsystems and
functions.
i Please read the information on qualified
specialist workshops (Y page 28).Important safety notes
G
WARNING
Tyres, wheels or accessories which have not
been approved by Mercedes-Ben zfor your
vehicle or are not used as they should be, can
impair driving safety. As a result, you could
cause an accident .Before purchasing and
using them, enquire about their suitability,
legal stipulations and factory recommenda-
tions at a Mercedes-Benz Service Centre.
Modification work on the brake system and
wheels is not permitted, nor is the use of
spacer plates or brake dust shields. This inva-
lidates the General Operating Permit for the
vehicle.
i Further information about tyres and
wheels can be obtained from any
Mercedes-Benz Service Centre. Operation
Notes on driving
R While driving, pay attention to vibrations,
noises and unusual handling characteris-
tics, e.g. pulling to one side. This may indi-
cate that the wheels or tyres are damaged.
If you suspect that a tyre is defective,
reduce your speed immediately. Stop the vehicle as soon as possible to chec
kthe
wheels and tyres for damage. Hidden tyre
damage could also be causing the unusual
handling characteristics. If you find no
signs of damage, have the wheels and tyres
examined at a qualified specialist work-
shop, e.g. a Mercedes-Ben zService
Centre.
R When parking your vehicle, make sure that
the tyres do not get deformed by the kerb
or other obstacles. If it is necessary to drive
over kerbs, speed humps or similar eleva-
tions, try to do so slowly and at an obtuse
angle. Otherwise, the tyres, particularly the
sidewalls, can get damaged. Notes on regularly inspecting wheels
and tyres
R Regularly chec kthe wheels and tyres of
your vehicle for damage (e.g. cuts, punctu-
res, tears, bulges on tyres and deformation,
cracks or severe corrosion on wheels), at
least every 14 days, as well as after driving
off-road or on rough roads. Damaged
wheels can cause a loss of tyre pressure.
R Regularly check the tyre tread depth and
the condition of the tread across the whole
width of the tyre (Y page 359). If neces-
sary, turn the front wheels to full lock in
order to inspect the inner side of the tyre
surface.
R All wheels must have a valve cap to protect
the valve against dirt and moisture. Do not
fit anything onto the valve (such as tyre
pressure monitoring systems) other than
the standard valve cap or other valve caps
approved by Mercedes-Ben zfor your vehi-
cle.
R Regularly check the pressure of all the tyres
including the emergency spare wheel or the
spare wheel, particularly prior to long trips,
and correc tthe pressure as necessary
(Y page 361). 358

the work required. Mercedes-Benz recom-
mends tha tyou use a Mercedes-Benz Service
Centre for this purpose. In particular, work
relevant to safety or on safety-related sys-
tems must be carried out at a qualified spe-
cialist workshop.
The wheels could work loose if they are not
tightened to a torque of 130 Nm.
For safety reasons, Mercedes-Benz recom-
mends that you only use wheel bolts of the
correc tsize which have been approved for
Mercedes-Ben zvehicles.
The wear patterns on the fron tand rea rtyres
differ, depending on the operating conditions.
Interchange the wheels befor eaclear wear
pattern has formed on the tyres. Front tyres
typically wear more on the shoulders and the
rear tyres in the centre.
On vehicles that have the same size front and
rea rwheels, you can interchange the wheels
every 5000 km to 10,000 km depending on
the degree of tyre wear. Do not reverse the
direction of tyre rotation.
Cleant he contact surfaces of the wheel and
the brake disc thoroughly every time a wheel
is interchanged. Check the tyre pressure and,
if necessary, restart the tyre pressure loss
warning system or the tyre pressure monitor.
! On vehicles fitted with a tyre pressure
monitor, electronic components are loca-
ted in the wheel.
Tyre-fitting tools should not be applied in
the area of the valve, as this could damage
the electronic components.
Always have the tyres changed at a quali-
fied specialist workshop, e.g. a Mercedes-
Benz Service Centre. Direction of rotation
Tyres with a specified direction of rotation
have additional benefits, e.g. if there is a risk
of aquaplaning. You will only gain these ben-
efits if the correct direction of rotation is
observed. An arrow on the sidewall of the tyre indicates
its correct direction of rotation.
You may fit an emergency spare wheel/spare
wheel against the direction of rotation.
Observe the time restriction on use as well as
the speed limitation specified on the emer-
gency spare wheel/spare wheel. Storing wheels
Store wheels that are not being used in a cool,
dry and preferably dark place. Protect the
tyres against oil, grease, petrol and diesel. Cleaning the wheels
G
WARNING
Do not use high-pressure cleaners with circu-
lar-jet nozzles (dirt grinders) to clean your
vehicle, in particular the tyres. You could oth-
erwise damage the tyres and cause an acci-
dent. Wheel and tyre combinations

Mercedes-Benz Service Centre. Genuine Mercedes-Benz parts
Mercedes-Ben ztests genuine parts and con-
version parts and accessories which have
been specifically approved for your vehicle for
their reliability, safety and suitability. Despite
ongoing market research, Mercedes-Benzis
unable to evaluate other parts. Mercedes-
Ben ztherefore accepts no responsibility for
the use of such parts in Mercedes-Ben zvehi-
cles, even if they have been independently or
officially approved.
In Germany and some other countries, certain
parts are only officially approved for installa-
tion or modification if they comply with legal
requirements. All genuine Mercedes-Benz
parts meet this requirement .The use of non- approved parts may invalidate the vehicle's
general operating permit. This is the case if:
R
they cause a change of the vehicle type
from that for which the vehicle's general
operating permit was granted.
R other road users could be endangered.
R the emission or noise levels are adversely
affected. G
WARNING
Driving safety may be impaired if non-
approved parts, tyres and wheels or safety-
relevant accessories are used.
This could lead to malfunctions in safety-rel-
evant systems, e.g. the brake system. This
could cause you to lose control of your vehicle
and cause an accident.
For this reason, Mercedes-Ben zrecommends
that you use genuine Mercedes-Benz parts or
parts of equal quality. Only use tyres, wheels
and accessories that have been specifically
approved for your vehicle.
! Airbags and seat belt tensioners, as well
as control units and sensors for these
restraint systems may be installed in the
following areas of your vehicle:
R doors
R door pillars
R door sills
R seats
R dashboard
R instrument cluster
R centre console
Do not install accessories such as audio
systems in these areas. Do not carry out
repairs or welding. You could impair the
operating efficiency of the restraint sys-
tems.
Have aftermarket accessories installed at
a qualified specialist workshop. Mercedes-
Benz recommends that you use a
Mercedes-Benz Service Centre for this pur-
pose. 376

therefore strongly recommended to observe
regular oil changes using an approved engine
oil with the appropriate SAE classification. Brake fluid
G
WARNING
Ove raperiod of time, the brake fluid absorbs
moisture from the air; This lowers its boiling
point.
If the boiling point of the brake fluid is too low,
vapour pockets may form in the brake system
when the brakes are applied hard (e.g. when
driving downhill). This impairs braking effi-
ciency.
You should have the brake fluid renewed at
regular intervals. The brake fluid change inter-
vals can be found in the Service Booklet.
Only use brake fluid approved by Mercedes-
Benz. Information about approved brake flu-
ids can be obtained from any Mercedes-Benz
Service Centre or on the Internet at
http://bevo.mercedes-benz.com
i There is usually a notice in the engine
compartment to remind you when the next
brake fluid change is due. Coolant
Important safety notes The coolant is a mixture of water and anti-
freeze/corrosion inhibitor. It performs the
following tasks:
R
anti-corrosion protection
R antifreeze protection
R raising the boiling point
i When the vehicle is first delivered, it is fil-
led with a coolant mixture that ensures
adequate antifreeze and corrosion protec-
tion.
! Only add coolant that has been premixed
with the desired antifreeze protection. The
engine could otherwise be damaged.
Further information on coolants and on fill-
ing can be found in the Mercedes-Benz
Specifications for Service Products, MB
Approval 310.1, e.g. on the Internet at
http://bevo.mercedes-benz.com .You can
also consult a Mercedes-Benz Service
Centre.
! Always use a suitable coolant mixture,
even in countries where high temperatures
prevail.
Otherwise, the engine cooling system is not
sufficiently protected from corrosion and
overheating.
If antifreeze/corrosion inhibitor is present in
the correc tconcentration, the boiling point of
the coolant during operation will be around
130 †.
The antifreeze/corrosion inhibitor concentra-
tion in the engine cooling system should:
R be at least 50%. This will protec tthe engine
cooling system against freezing down to
around -37 †.
R not exceed 55% (antifreeze protection
down to -45 †); otherwise, heat will not be
dissipated as effectively.
If the vehicle has lost coolant, top it up with
equal amounts of water and antifreeze/cor- Service products and capacities
