! Always use wheel bolts : to fit the
"Minispare" emergency spare wheel with
light-alloy wheel. Using other wheel bolts
when fitting the "Minispare" emergency
spare wheel with light-alloy wheel could
damage the brake system.
Always use wheel bolts ; to fit the
"Minispare" emergency spare wheel with
steel wheel. Using other wheels when
fitting the "Minispare" emergency spare
wheel with steel wheel could damage the
brake system.
XClean the wheel and wheel hub contact
surfaces.
! To prevent damage to the paintwork, hold
the wheel securely against the wheel hub
while screwing in the first wheel bolt.
XSlide the emergency spare wheel onto the
alignment bolt and push it on.
XTighten the wheel bolts until they are
finger-tight.
XUnscrew the alignment bolt.XTighten the last wheel bolt until it is finger-
tight.
Lowering the vehicle
XTurn the crank of the jack counter-
clockwise until the vehicle is once again
standing firmly on the ground.
XPlace the jack to one side.XTighten the wheel bolts evenly in a
crosswise pattern in the sequence
indicated (: to A). The tightening torque
must be 110 lb/ft (150 Nm).
GWarning
Have the tightening torque checked
immediately after a wheel is changed. The
wheels could come loose if they are not
tightened to a torque of 110 lb/ft
(150 Nm).
XTurn the jack back to its initial position and
store it together with the rest of the vehicle
tool kit in the stowage well under the trunk
floor.
iWhen you are driving with the emergency
spare wheel mounted, the tire pressure
monitor cannot function reliably. Only
restart the tire pressure monitor when the
defective wheel has been replaced with a
new wheel.
All mounted wheels must be equipped with
functioning sensors and the defective
wheel should no longer be in the vehicle.
MOExtended run-flat system
The MOExtended run-flat system allows you
to drive on even if there is a complete loss of
pressure in one or more tires.
The MOExtended run-flat system may only be
used in conjunction with the activated tire
pressure loss warning system or with the
activated tire pressure monitor.

Tire bead
The tire bead ensures that the tire sits
securely on the wheel. There are several steel
wires in the bead to prevent the tire from
coming loose from the wheel rim.
Sidewall
The part of the tire between the tread and the
tire bead.
Weight of optional extras
The combined weight of those optional extras
that weigh more than the replaced standard
part and more than 2.3 kilograms (5 lbs).
These optional extras, such as high-
performance brakes, level control, a roof rack
or a high-performance battery, are not
included in the unladen weight and the weight
of the accessories.
TIN (Tire Identification Number)
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.
Wear indicator
This is indicated by 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
This is the 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 "Breakdown assistance" section
( Y page 463) contains information and notes
on how to deal with a flat tire. It also provides
instructions on changing a wheel or installing
the spare wheel or emergency 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. The wheels could come
loose if they are not tightened to a torque of
110 lb-ft (150 Nm).
Only use genuine Mercedes-Benz wheel bolts
specified for your vehicle’s rims.
