409 Practical hints
Flat tire
Insert electrical plug 3 into vehicle
cigarette lighter socket (
page 263).
Turn the SmartKey in the starter switch
to position1.
PressI on electric air pump switch 2.
The electric air pump should now
switch on and inflate the collapsible
tire.
Inflate the tire to approximately 51 psi
(3.5 bar).
This takes about 5 minutes for the col-
lapsible tire. Air hose 4 and union
nut5 can become hot during infla-
tion. Exercise proper caution to avoid
burning yourself when using the equip-
ment.
Press0 on electric air pump switch 2.
Turn the SmartKey in the starter switch
to position0.
If the tire pressure is above 51 psi
(3.5 bar), release excess tire pressure
using the vent screw.
Detach the electric air pump.
Store the electrical plug and the air
hose behind the flap and place the
electric air pump back in the trunk.
!
The cigarette lighter (page 262) is
not designed for use with the electric
air pump. Use the power outlet in the
rear passenger compartment
(
page 263) for electric air pump
operation.
!
Do not operate the electric air pump
longer than 6 minutes without interrup-
tion. Otherwise it may overheat.
You may operate the electric air pump
again after it has cooled off.
Warning!G
Follow recommend inflation pressures.
Do not overinflate tires. Overinflating tires
can result in sudden deflation (blowout) be-
cause they are more likely to become punc-
tured or damaged by road debris, potholes,
etc.
Do not underinflate tires. Underinflated tires
wear unevenly, adversely affect handling
and fuel economy, and are more likely to fail
from being overheated.

Only use tires which have been tested
and approved for your vehicle by
Mercedes-Benz. Tires approved by
Mercedes-Benz are developed to pro-
vide best possible performance in con-
junction 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 side-
wall:
MO = Mercedes-Benz Original
equipment tires
AMG vehicles:
Does not apply to all approved tires
on AMG vehicles. For information
on tested and approved tires for
AMG vehicles, contact an autho-
rized Mercedes-Benz Center.
Using tires other than those approved
by Mercedes-Benz may result in dam-
age that is not covered by the
Mercedes-Benz Limited Warranty.
!
Using tires other than those approved
by Mercedes-Benz can have detrimen-
tal effects, such as
poor handling characteristics
increased noise
increased fuel consumption
Moreover, tires and rims not approved
by Mercedes-Benz may, under load,
exhibit dimensional variations and dif-
ferent tire deformation characteristics
that could cause them to come into
contact with the vehicle body or axle
parts. Damage to the tires or the vehi-
cle may be the result.
i
Further 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. Some vehicles may have
supplemental tire inflation pressure
information for driving at high speeds
(
page 316) or for vehicle loads less
than the maximum loaded vehicle
condition (
page 316). If such infor-
mation is provided, it can be found on
the placard located on the inside of the
fuel filler flap. The tire inflation pres-
sure should be checked regularly and
should only be adjusted on cold tires.
Follow tire manufacturer’s mainte-
nance recommendation included with
vehicle.

The following pages also list the ap-
proved 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 (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. See an authorized
Mercedes-Benz Center for more infor-
mation.

Please compare the recommended tire
inflation pressure for your vehicle with
the tire inflation pressure on the yellow
label located on the spare wheel rim.
If the tire inflation pressure on the yel-
low label on the spare wheel rim differs
from the values given in this Operator’s
Manual, inflate the collapsible tire to
the recommended tire inflation pres-
sure given on the yellow label on the
spare wheel rim.
i
Please note that the tire inflation
pressure of the collapsible tire differs
from the tire inflation pressure of the
road tires.
Inflate the collapsible tire to approxi-
mately 51 psi (3.5 bar).
