445 Practical hints
Flat tire
Guide the Minispare wheel onto the
wheel hub and push it on.
Insert wheel bolts and tighten them
slightly.
Lowering the vehicle
Lower vehicle by turning crank
counterclockwise until vehicle is
resting fully on its own weight.
Remove the jack.1 - 5 Wheel bolts
6 Wheel wrench
Tighten the five wheel bolts evenly,
following the diagonal sequence
illustrated (1 to 5), until all bolts are
tight. Observe a tightening torque of
96 lb-ft (130 Nm).
Before storing the jack, it should be fully
collapsed, with handle folded in (storage
position).
Store the jack and the other vehicle
tools in the designated storage space
underneath the trunk floor
(
page 420).
Warning!G
Have the tightening torque checked after
changing a wheel. The wheels could come
loose if they are not tightened to a torque of
96 lb-ft (130 Nm).
iVehicles with TPMS (USA only):
Do not activate the tire inflation pressure
monitor (
page 344) until a full size wheel/tire
with functioning sensor has been placed back
into service on the vehicle.

467 Technical data
Rims and tires
Rims and tires
!Only use tires which have been tested and
approved for your vehicle by Mercedes-Benz.
Tires approved by Mercedes-Benz are developed
to provide best possible performance in conjunc-
tion with the driving safety systems on your
vehicle such as ABS or ESP
®. Tires specially
developed for your vehicle and tested and
approved by Mercedes-Benz can be identified by
finding the following on the tire’s sidewall:

MO = Mercedes-Benz Original equipment
tires
Using tires other than those approved by
Mercedes-Benz may result in damage that is not
covered by the Mercedes-Benz Limited
Warranty.
!Using tires other than those approved by
Mercedes-Benz can have detrimental effects,
such as

poor handling characteristics

increased noise

increased fuel consumption
Moreover, tires and rims not approved by
Mercedes-Benz may, under load, exhibit dimen-
sional variations and different tire deformation
characteristics that could cause them to come
into contact with the vehicle body or axle parts.
Damage to the tires or the vehicle may be the
result.
iFurther information on tires and rims is
available at any authorized Mercedes-Benz
Center. A placard with the recommended tire
inflation pressures is located on the driver’s door
B-pillar (
page 334). Some vehicles may have
supplemental tire inflation pressure information
for driving at high speeds (
page 340) or for
vehicle loads less than the maximum loaded
vehicle condition (
page 348). If such informa-
tion is provided, it can be found on the tire infla-
tion label located on the inside of the fuel filler
flap. The tire inflation pressure should be checked
regularly and should only be adjusted on cold
tires. Follow tire manufacturer’s maintenance
recommendation included with vehicle.
iThe following pages also list the approved
wheel rim and tire sizes for equipping your
vehicles with winter tires. Winter tires are not
available as standard or optional factory equip-
ment, but can be purchased from an authorized
Mercedes-Benz Center.
Depending on vehicle model and the standard or
optional factory-equipped wheel rim/tire
configuration on your vehicle (Appearance
Package, Sport Package etc.), equipping your
vehicle with winter tires approved for your
vehicle model may also require the purchase of
two or four wheel rims of the recommended size
for use with these winter tires. Contact an autho-
rized Mercedes-Benz Center for more informa-
tion.

472 Technical data
Rims and tires
!Please compare the recommended tire in-
flation pressure for your vehicle with the tire in-
flation pressure on the yellow label located on
the Minispare wheel rim.
If the tire inflation pressure on the yellow label
on the Minispare wheel rim differs from the
values given in this Operator’s Manual, inflate
the Minispare wheel tire to the recommended
tire inflation pressure given on the yellow label
on the Minispare wheel rim.
iPlease note that the tire inflation pressure
of the Minispare differs from the tire inflation
pressure of the road tires.
Make sure the Minispare tire is inflated to
approximately 61 psi (4.2 bar).
