2012 MERCEDES-BENZ SL-CLASS ROADSTER tires

Underinflation also reduces fuel efficiency
and tire tread life, and may affect the vehicle’s
handling and stopping ability. Please note that
the TPMS is not a substitute for proper tire
maintenance, and it is the driver’s
responsibility to maintain correct tire
pressure, even if underinflation has not
reached the level to trigger illumination of the
TPMS low tire pressure telltale.
USA only:
Your vehicle has also been equipped with a
TPMS malfunction indicator to indicate when
the system is not operating properly. The
TPMS malfunction indicator is combined with
the low tire pressure telltale. When the
system detects a malfunction, the telltale will
flash for approximately 1 minute and thenremain continuously illuminated. This
sequence will continue upon subsequent
vehicle start-ups as long as the malfunction
exists. When the malfunction indicator is
illuminated, the system may not be able to
detect or signal low tire pressure as intended.
TPMS malfunctions may occur for a variety of
reasons, including the installation of
incompatible replacement or alternate tires
or wheels on the vehicle that prevent the
TPMS from functioning properly. Always
check the TPMS malfunction telltale after
replacing one or more tires or wheels on your
vehicle to ensure that the replacement or
alternate tires and wheels allow the TPMS to
continue to function properly.

Be careful not to damage the locking tabs
or clamp the plastic retaining strap.
MOExtended system
The MOExtended system allows you to
continue driving your vehicle even if there is
a total loss of pressure in one or more tires.
You may only use the MOExtended system in
conjunction with the Advanced TPMS
( Y page 190).
The maximum distance in emergency mode
depends on the vehicle’s load. It is 50 miles
(80 km) if the vehicle is partially loaded and
18 miles (30 km) if the vehicle is fully loaded.
The point at which the maximum driving
distance in emergency mode begins is when
the warning message appears in the
multifunction display indicating that there is
a loss of tire inflation pressure.
XDo not exceed the maximum speed of
50 mph (80 km/h).GWarning!
In emergency mode, your vehicle’s driving
characteristics are diminished in such
situations as:
R driving around curves
R while braking
R while accelerating rapidly
Therefore, your driving style must be adapted
accordingly. Avoid abrupt steering and driving
maneuvers, as well as driving over obstacles
(road curbs, potholes, or off-road areas). This
is especially important if the vehicle is heavily
loaded.
The emergency driving distance that can be
achieved greatly depends on the demands
placed on the vehicle. Depending on speed,
load, driving maneuvers, road conditions,
outside temperature, etc., the distance can be
significantly shorter or, if the vehicle is driven
cautiously, somewhat longer.
Do not continue driving in emergency mode if
R you notice knocking sounds
R the vehicle starts to shake
R smoke develops and you smell rubber
R ESP ®
is intervening continuously
R you notice tears on the tire sidewalls
After driving in emergency mode, you must
have the rims inspected by an authorized
Mercedes-Benz Center to check if they are
suitable for further use. The failed tire must
be replaced in any case.
When replacing individual or all tires on the
vehicle, make sure only tires marked with
“MOExtended” are mounted in the size
specified for your vehicle ( Y page 299).
Battery
Safety notes
These batteries should always be sufficiently
charged in order to achieve their rated service
life. Refer to Maintenance Booklet for battery
maintenance intervals.
If you use your vehicle mostly for short-
distance trips, you will need to have the
battery charge checked more frequently.
When replacing a battery, always use a
battery approved by Mercedes-Benz.
If you do not intend to operate your vehicle
for an extended period of time, contact an
authorized Mercedes-Benz Center about
steps you need to observe.
GWarning!
Observe all safety instructions and
precautions when handling automotive
batteries.

Rims and tires
Notes
! Only use tires which have been tested and
approved by Mercedes-Benz. Tires
approved by Mercedes-Benz are developed
to provide best possible performance in
conjunction with the driving safety systems
on your vehicle such as the ABS or the
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:
R MO =
Mercedes-Benz Original
equipment tires
R MO1 =
Mercedes-Benz Original
equipment tires (applicable to selected
tire sizes only)
R MOE =
Mercedes-Benz Original Extended
(tires with limited run-flat
characteristics) 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.
For information on driving with MOExtended
tires, see the “Practical hints” section
( Y page 283).
! Using tires other than those approved by
Mercedes-Benz can have detrimental
effects, such as
R poor handling characteristics
R increased noise
R increased fuel consumption
Moreover, tires and rims not approved by
Mercedes-Benz may, under load, exhibit
dimensional 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.
i Further information on tires and rims is
available at any authorized Mercedes-Benz
Center. The Tire and Loading Information
placard with the recommended tire
inflation pressures for cold tires is located
on the driver’s door B-pillar. Supplemental
tire inflation pressure information for
driving at high speeds or for vehicle loads
less than the maximum loaded vehicle
condition can be found on the tire inflation
pressure label. The tire inflation pressure
label is located on the inside of the fuel fillerflap. The tire inflation pressure should be
checked regularly and should only be
adjusted on cold tires. Follow tire
manufacturer’s maintenance
recommendation included with the vehicle.
For information on recommended tire
inflation pressure and supplemental tire
inflation pressure information for special
driving situations, see ( Y page 187).
i Please keep in mind that the vehicle must
be equipped
R with wheels of identical dimensions on
each axle (left and right)
R with tires of identical characteristics all
around, i.e. summer tires, winter tires,
all-season tires, or MOExtended tires etc.
i The following pages also list the approved
rim and tire sizes for equipping your vehicle
with winter tires. Winter tires are not
available as standard or optional factory
equipment, but can be purchased from an
authorized Mercedes-Benz Center.
Equipping your vehicle with winter tires
approved for your vehicle model may
require the purchase of rims of the
recommended size for use with these
winter tires. This depends on vehicle model
and the standard or optional factory-
equipped wheel rim/tire configuration on
your vehicle. For more information contact
an authorized Mercedes-Benz Center.300Rims and tiresTechnical data

Spare wheel
! 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 yellow label on the spare wheel rim differs from the values
given in this Operator’s Manual, inflate the tire to the recommended tire inflation pressure
given on the yellow label on the spare wheel rim.
i Please note that the tire inflation pressure of the spare wheel differs from the tire inflation
pressure of the road tires.SL 550
