The brake system continues to function normally, but without the
functions listed above. The wheels could therefore lock if you
brake hard, for example.

Vehicle equipment
i This manual describes all the standard
and optional equipment of your vehicle
which was available at the time of
purchase. Country-specific differences are
possible. Bear in mind that your vehicle
may not feature all functions described
here. This also refers to safety-related
systems and functions.
Important safety notes
Contact an authorized Mercedes-Benz Center
if you require information on tested and
recommended tires and wheels for summer
and winter driving. Advice on purchasing and
caring for tires is also available there.
GWarning
Replace rims or tires with the same
designation, manufacturer and type as shown
on the original part. For further information
contact an authorized Mercedes-Benz Center.
If incorrectly sized rims and tires are
mounted, the wheel brakes or suspension
components can be damaged. Also, the
operating clearance of the wheels and the
tires may no longer be correct.
GWarning
Worn, old tires can cause accidents. If the tire
tread is worn to minimum tread depth, or if
the tires have sustained damage, replace
them.
When replacing rims, only use genuine
Mercedes-Benz wheel bolts specified for the
particular rim type. Failure to do so can result
in the bolts loosening and possibly an
accident.
Retreaded tires are not tested or
recommended by Mercedes-Benz, since
previous damage cannot always be
recognized on retreads. The operating safety
of the vehicle cannot be assured when such
tires are used.
GWarning
If you feel a sudden significant vibration or
ride disturbance, or you suspect that possible
damage to your vehicle has occurred, you
should turn on the hazard warning flashers,
carefully slow down, and drive with caution to
an area which is a safe distance from the road.
Inspect the tires and the vehicle underbody
for possible damage. If the vehicle appears
unsafe, have the vehicle towed to the nearest
authorized Mercedes-Benz Center or tire
dealer for repairs.
GWarning
Do not drive with a flat tire. A flat tire affects
the ability to steer or brake the vehicle. You
might lose control of the vehicle. Continued
driving with a flat tire or driving at high speed
with a flat tire will cause excessive heat build-
up and possibly a fire.
! For safety reasons, Mercedes-Benz
recommends that you only use tires,
wheels and accessories which have been
approved by Mercedes-Benz specifically
for your vehicle. These tires have been
specially adapted for use with the control
systems, such as ABS or ESP ®
, and are
marked as follows:
R MO = Mercedes-Benz Original
R MOE = Mercedes-Benz Original Extended
(tires with run-flat characteristics)
R MO1 = Mercedes-Benz Original (AMG)
Only use Mercedes-Benz Original Extended
tires on wheels that have been specifically
approved by Mercedes-Benz.
If you use other tires, wheels and
accessories, Mercedes-Benz cannot
accept any responsibility for damage that
may result from this. Further information
about tires, wheels and approved
combinations can be obtained from any
authorized Mercedes-Benz Center.

GWarning
Observe the "Important safety information"
( Y page 334).
! For safety reasons, Mercedes-Benz
recommends that you only use tires,
wheels and accessories which have been
approved by Mercedes-Benz specifically
for your vehicle. These tires have been
specially adapted for use with the control
systems, such as ABS or ESP ®
, and are
marked as follows:
R MO = Mercedes-Benz Original
R MOE = Mercedes-Benz Original Extended
(tires with run-flat characteristics)
R MO1 = Mercedes-Benz Original (AMG)
Only use Mercedes-Benz Original Extended
tires on wheels that have been specifically
approved by Mercedes-Benz.
If you use other tires, wheels and
accessories, Mercedes-Benz cannot
accept any responsibility for damage that
may result from this. Further information
about tires, wheels and approved
combinations can be obtained from any
authorized Mercedes-Benz Center.
! If you mount tires other than those tested
and recommended by Mercedes-Benz,
characteristics such as handling, noise
levels and fuel consumption, etc. may be
adversely affected. In addition, when
driving with a load, tire dimensional
variations could cause the tires to come
into contact with the bodywork and axle
components. This could result in damage
to the tires or the vehicle.
i Further information about tires and
wheels can be obtained from any
authorized Mercedes-Benz Center.
i The Tire and Load Information placard
with the recommended tire pressures is
attached to the B-pillar on the driver's side.
Further information about driving at high
speeds or driving with vehicle loads that are
lighter than the maximum vehicle load can
be found in the tire pressure table on the
inside of the fuel filler flap. Check tire
pressures regularly, and only when the tires
are cold. Comply with the maintenance
recommendations of the tire manufacturer
in the vehicle document wallet.
Further information on the recommended tire
inflation pressure and on tire pressures for
specific driving conditions, see (Y page 336).
i Notes on the vehicle equipment:
R always mount tires of the same size on a
given axle (left/right).
R always mount the same type of tires on
your vehicle at a given time (summer
tires, winter tires, MOExtended tires).
i Vehicles featuring the MOExtended run-
flat system are not equipped with a TIREFIT
kit.
It is therefore recommended that you
additionally equip your vehicle with the
TIREFIT kit if you mount tires that do not
feature run-flat properties, e.g. winter tires.
A TIREFIT kit is available from any qualified
specialist workshop, e.g. an authorized
Mercedes-Benz Center.
i The following pages contain information
on approved wheel rims and tire sizes for
equipping your vehicle with winter tires.

Lubricant additives
! Do not mix any lubricant additives with
the engine oil. This could damage the
engine. Damage resulting from the use of
such lubricant additives in the engine oil is
not covered by the Mercedes-Benz Limited
Warranty.
Engine oil viscosity
Viscosity describes the flow characteristics
of a fluid. If an engine oil has a high viscosity,
this means that it is thick; a low viscosity
means that it is thin.
Using the table below, make sure that the SAE
classification (viscosity) is sufficient for the
temperatures at which the vehicle is
operated. The low temperature
characteristics of engine oils can deteriorate
significantly, e.g by aging, soot and fuel
deposits. It is therefore recommended that
you carry out oil changes regularly using an
approved engine oil with the appropriate SAE
classification.
Refrigerant of the air-conditioning
system
The air-conditioning system is filled with
R134a refrigerant and a special PAG
lubricant.
! Never use refrigerant R 12 (CFC) or
mineral lubricants. Otherwise, you could
damage the air-conditioning system.
Brake fluid
GWarning!
The brake fluid constantly absorbs moisture
from the air; this lowers its boiling point.
If the boiling point of the brake fluid is too low,
vapor pockets may form in the brake system
when the brakes are applied hard (e.g. when
driving downhill). This would impair braking
efficiency.
You should have the brake fluid renewed at
regular intervals. The brake fluid change
intervals can be found in the Service Booklet.
Only use brake fluid approved by Mercedes-
Benz. Information about approved brake
fluids can be obtained from any authorized
Mercedes-Benz Center.
Coolant
Important safety notes
The coolant is a mixture of water and
antifreeze/corrosion inhibitor. It performs
the following tasks:
R anti-corrosion protection
R antifreeze protection
R raising the boiling point
The cooling system is filled with coolant at the
factory which contains antifreeze/corrosion
inhibitor that ensures protection down to
approximately -35 ‡ (-37 †).
