performance battery, are not included in the
curb weight and the weight of the
accessories.
TIN (Tire Identification Number)
This is a unique identification number which
can be used by a tire manufacturer to identify
tires, for example for a product recall, and
thus identify the purchasers. The TIN is made
up of the manufacturer's identity code, tire
size, tire type code and the manufacturing
date.
Load bearing index
The load bearing index (also load index) is a
code that contains the maximum load bearing
capacity of a tire.
Traction
Traction is the result of friction between the
tires and the road surface.
TWR (permissible trailer drawbar
noseweight)
The TWR is the maximum permissible weight
that may act on the ball coupling of the trailer
tow hitch.
Wear indicator
Narrow bars (tread wear bars) that are
distributed over the tire tread. If the tire tread
is level with the bars, the wear limit of 1
/ 16 in
(1.6 mm) has been reached.
Distribution of the vehicle occupants
Distribution of vehicle occupants over
designated seat positions in a vehicle.
Maximum permissible payload
weight
Nominal load and luggage load plus
68 kilograms (150 lb) multiplied by the
number of seats in the vehicle.
Changing a wheel
Flat tire
The "Roadside Assistance" section
( Y page 232) contains information and notes
on how to deal with a flat tire. It also provides
instructions on changing a wheel or mounting
the spare wheel.
Interchanging the wheels
GWarning
Rotate front and rear wheels only if the tires
are of the same dimension.
If your vehicle is equipped with mixed-size
tires (different tire dimensions front vs. rear),
tire rotation is not possible.
GWarning!
Have the tightening torque checked after
changing a wheel. Wheels could become
loose if not tightened with a torque of
96 lb-ft (130 Nm).
Only use genuine Mercedes-Benz wheel bolts
specified for your vehicle's rims.
The wear patterns on the front and rear tires
differ, depending on the operating conditions.
Rotate the wheels before a clear wear pattern
has formed on the tires. Front tires typically
wear more on the shoulders and the rear tires
in the center.
If your vehicle's tire configuration allows, you
can rotate the wheels according to the
intervals in the tire manufacturer's warranty
book in your vehicle documents. If no
warranty book is available, the tires should be
rotated every 3000 to 6000 miles
(5000 to 10000 km), or earlier if tire wear

requires. Do not change the direction of
wheel rotation.
Clean the contact surfaces of the wheel and
the brake disc thoroughly every time a wheel
is interchanged. Check the tire pressure and
reactivate the tire pressure monitor
( Y page 253) if necessary.
Information on changing a wheel and
mounting the spare wheel ( Y page 232).
! On vehicles installed with a tire pressure
monitor, electronic components are
located in the wheel.
Tire-mounting tools should not be applied
in the area of the valve, as this could
damage the electronic components.
Always have the tires changed at a qualified
specialist workshop, e.g. an authorized
Mercedes-Benz Center.
Direction of rotation
Tires with a specified direction of rotation
have additional benefits, e.g. if there is a risk
of hydroplaning. You will only gain these
benefits if the correct direction of rotation is
maintained.
An arrow on the sidewall of the tire indicates
its correct direction of rotation.
You may install the spare wheel against the
direction of rotation. Adhere to the time
restriction on use as well as the speed
limitation specified on the spare wheel.
Storing wheels
Store tires that are not being used in a cool,
dry and preferably dark place. Protect the
tires from oil, grease, gasoline and diesel.
Cleaning the wheels
GWarning
Do not use power washers with circular jet
nozzles (concentrated-power jets) to clean
your vehicle, especially for cleaning tires. You
could otherwise damage the tires and cause
an accident.
Wheel and tire combinations
Please bear the following in mind
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
Mercedes-Benz Original Extended tires
may only be used on wheels that have been
specifically approved by Mercedes-Benz.
Only use tires, wheels or accessories
tested and approved by Mercedes-Benz.
Certain characteristics, e.g. handling,
vehicle noise emissions or fuel
consumption, may otherwise be adversely
affected. In addition, when driving with a
load, tire dimension 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.
Mercedes-Benz accepts no liability for
damage resulting from the use of tires,
wheels or accessories other than those
tested and approved.
Further information about tires, wheels and
approved combinations 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.
For further information on the recommended
tire inflation pressure and on tire pressures
for specific driving conditions, see
( Y page 249).
i Notes on vehicle tires:
Always:
R mount tires of the same size on a given
axle (left/right)
R mount tires of the same type on your
vehicle at a given time (summer tires,
winter tires, all-weather tires, all-terrain
tires)
i The following pages contain information
on approved wheels and tire sizes for
equipping your vehicle with winter tires.
Winter tires are not available at the factory
as standard equipment or optional extras.
If you wish to fit approved winter tires to
your vehicle, wheels of appropriate size
may also be required as the sizes of the
approved winter tires may differ from those
of the original tires. This is dependent on
the model and the equipment installed at
the factory.
Wheels and tires as well as additional
information are available from a qualified
specialist workshop, e.g. an authorized
Mercedes-Benz Center.

Important safety notesGWarning
Gasoline is highly flammable and poisonous.
It burns violently and can cause serious
personal injury.
Never allow sparks, flames or smoking
materials near gasoline.
Turn off the engine before refueling.
Whenever you are around gasoline, avoid
inhaling fumes and any skin or clothing
contact.25 Mixed with water or premixed washer fluid with antifreeze protection.Service products and capacities277Technical dataZProCarManuals.com

Brake fluidGWarning
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 engine cooling system is filled at the
factory with coolant which contains an
antifreeze/corrosion inhibitor that ensures
protection down to approximately -35 ‡
(-37 †).
! Only add coolant that has been premixed
with the desired antifreeze protection. You
could otherwise damage the engine.
Further information on coolants and on
filling 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 an authorized Mercedes-
Benz Center.
! 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
the boiling point will be too low.
If the coolant has antifreeze protection down
to -35 ‡ (-37 †), the boiling point of the
coolant in the pressurized system is
approximately 266 ‡ (130 †).
Your vehicle has a range of aluminum
components. Use of aluminum components
in the engine make it necessary to specifically
match the antifreeze/corrosion inhibitor in
these systems in order to protect the
aluminum parts. Using other antifreeze/
corrosion inhibitors without these
characteristics affects the service life.
The coolant must be used throughout the year
in order to maintain the necessary corrosion
protection and provide protection from
overheating. In the Service Booklet, you can
find information on the intervals for renewal.
The renewal interval is determined by the
coolant type and the engine cooling system
design. The renewal interval in the Service
Booklet is only valid if the coolant is renewed
or replenished with Mercedes-Benz approved
products. Therefore, only use MB 326.0
antifreeze/corrosion inhibitor or another
Mercedes-Benz approved product of the
same specification.
Information on other Mercedes-Benz
approved products of the same specification
can be obtained at any authorized Mercedes-
Benz Center or on the Internet at
http://bevo.mercedes-benz.com .
The coolant is checked at every service date
at an authorized Mercedes-Benz Center.280Service products and capacitiesTechnical data
ProCarManuals.com

The antifreeze/corrosion inhibitor
concentration in the engine cooling system
should:
R be at least 50%. This will protect the engine
cooling system against freezing down to
approximately -35 ‡ (-37 †).
R not exceed 55% (antifreeze protection to
-49 ‡ [-45 †]); heat will otherwise not
dissipate as effectively.
If the coolant level is too low, MB 325.0
antifreeze/corrosion inhibitor should be
added. Have the engine cooling system
checked for possible leaks.Engine cooling systemVehicle
