Important safety notes
G
WARNING
If wheels and tyres of the wrong size are used, the wheel brakes or suspension components
may be damaged. There is a risk of an acci-
dent.
Always replace wheels and tyres with those
that fulfil the specifications of the original
part.
When replacing wheels, make sure to fit the
correct:
R designation
R type
When replacing tyres, make sure to fit the
correct:

R manufacturer
R type G
WARNING
A flat tyre severely impairs the driving, steer-
ing and braking characteristics of the vehicle.
There is a risk of accident.
Tyres without run-flat characteristics:
R do not drive with a flat tyre.
R immediately replace the flat tyre with your
emergency spare wheel or spare wheel, or
consult a qualified specialist workshop.
Tyres with run-flat characteristics:
R pay attention to the information and warn-
ing notices on MOExtended tyres (tyres
with run-flat characteristics).
Accessories that are not approved for your vehi-
cle by Mercedes-Benz or are not being used cor- rectly can impair the operating safety.
Before purchasing and using non-approved
accessories, visit a qualified specialist work-
shop and enquire about:
R suitability
R legal stipulations
R factory recommendations Further information regarding wheels and tyres
can be found under "Wheel/tyre combinations"
(Y page 333).
You can ask for information regarding permitted
wheel-tyre combinations at a Mercedes-Benz
Service Centre.
Information on tyre pressures can be found:
R in the tyre pressure table in the fuel filler flap
(Y page 155)
R under "Tyre pressure" (Y page 324)
Modification work on the brake system and
wheels is not permitted. The use of spacers or
brake dust shields is not permitted. This inva-
lidates the general operating permit for the vehi- cle.
i Further information on wheels and tyres can
be obtained at any qualified specialist work-
shop. Operation
Information on driving
Check the tyre pressures when the vehicle is
heavily laden and adjust prior to a trip.
While driving, pay attention to vibrations, noises
and unusual handling characteristics, e.g. pull-
ing to one side. This may indicate that the
wheels or tyres are damaged. If you suspect that a tyre is defective, reduce your speed immedi-
ately. Stop the vehicle as soon as possible to
check the 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 tyres and wheels checked at a qualified specialist workshop.
When parking your vehicle, make sure not to
squash the tyre sidewalls. If this cannot be avoi-ded, drive slowly over obstacles, e.g. kerbs, and
only at an obtuse angle. You could otherwise
damage the wheel rims and tyres. Regular checking of wheels and tyres
G
WARNING
Damaged tyres can cause tyre inflation pres-
sure loss. As a result, you could lose control of your vehicle. There is a risk of accident. Operation

Interchanging the wheels
G
WARNING
Interchanging the front and rear wheels may
severely impair the driving characteristics if
the wheels or tyres have different dimensions. The wheel brakes or suspension components may also be damaged. There is a risk of acci-
dent.
Interchange front and rear wheels only if the
wheels and tyres are of the same dimensions.
! On vehicles fitted with a tyre pressure mon-
itor, electronic components are located in the wheel.
Tyre-fitting tools should not be applied in thearea of the valve, as this could damage the
electronic components.
Only have tyres changed at a qualified spe-
cialist workshop.
Interchanging the front and rear wheels of dif-
fering dimensions can render the general oper-
ating permit invalid.
Observe the instructions and safety notes in the "Fitting a wheel" section (Y page 329).
The wear patterns on the front and rear tyres
differ depending on the operating conditions.
Interchange the wheels before a clear wear pat-
tern has formed on the tyres. Front tyres typi-
cally wear more on the shoulders and the rear
tyres in the centre.
On vehicles that have the same size front and
rear wheels, you can interchange the wheels
every 5,000 to 10,000 km depending on the
degree of tyre wear. Ensure that the direction of
rotation is maintained.
Clean the 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 warn-
ing system (Y page 326) or the tyre pressure
monitor (Y page 328). Direction of rotation
Tyres with a specified direction of rotation have additional benefits, e.g. if there is a risk of aqua- planing. These advantages can only be gained if
the tyres are fitted corresponding to the direc-
tion of rotation. An arrow on the sidewall of the tyre indicates its
correct direction of rotation. 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. Fitting a wheel
Preparing the vehicle X
Stop the vehicle on solid, non-slippery and
level ground.
X Apply the parking brake.
X Move the front wheels to the straight-ahead
position.
X Vehicles with manual transmission:
depress the clutch pedal fully and engage first
or reverse gear.
X Vehicles with automatic transmission:
shift the automatic transmission to position
P.
X Switch off the engine.
X Remove the key from the ignition lock.
or, on vehicles with KEYLESS‑GO:
X Open the driver's door.
The on-board electronics now have status 0.
This is the same as the key having been
removed.
X Remove the Start/Stop button from the igni-
tion lock (Y page 139).
X If included in the vehicle equipment, remove
the tyre-change tool kit from the vehicle
(Y page 305).
X Safeguard the vehicle against rolling away.
i Apart from some country-specific variants,
vehicles are not equipped with tyre-changing
tools. Some tools for changing a wheel are
specific to the vehicle. For more information
on which tools are required to perform a
wheel change on your vehicle, consult a quali- fied specialist workshop.
Necessary tyre-changing tools may include,

the designation, e.g. 229.5.
The table shows which engine oils have been
approved for your vehicle.
Petrol engines: in certain countries, different
engine oils can be used, provided that the main-
tenance intervals are reduced. For more infor-
mation, please contact a qualified specialist

Do not use any additives with the engine oil.
This could damage the engine. Brake fluid
G
WARNING
The brake fluid continuously absorbs mois-
ture from the air. This results in the boiling
point of the brake fluid lowering. If the boiling
point of the brake fluid is too low, vapour
pockets may form when the brakes are sub-
jected to a heavy load. This would impair brak- ing efficiency. There is a risk of an accident.
Have the brake fluid renewed at the prescri-
bed intervals.
When handling brake fluid, observe the impor-
tant safety notes on service products
(Y page 337).
The brake fluid change intervals can be found in the Service Booklet.
Only use brake fluid approved by Mercedes-
Benz in accordance with MB-Freigabe or MB-
Approval 331.0.
Information about approved brake fluid can be
obtained at any qualified specialist workshop or on the Internet at
http://bevo.mercedes-benz.co m.
i Have the brake fluid regularly replaced at a
qualified specialist workshop and the replace- ment confirmed in the Service Booklet. Coolant
Important safety notes G
WARNING
If antifreeze comes into contact with hot com- ponents in the engine compartment, it may
ignite. There is a risk of fire and injury.
Let the engine cool down before you top up
the antifreeze. Make sure that antifreeze is
not spilled next to the filler neck. Thoroughly
clean the antifreeze from components before
starting the engine. Service products and capacities
