Warning!
Do not drive with a flat tire. A flat tire affects the ability to steer or brake the vehicle. You may
lose control of the vehicle. Continued driving with a flat tire will cause excessive heat build-up
and possibly a fire. G
Warning!
Follow recommended tire inflation pressures.
Do not underinflate tires. Underinflated tires wear excessively and/or unevenly, adversely affect
handling and fuel economy, and are more likely to fail from being overheated.
Do not overinflate tires. Overinflated tires can adversely affect handling and ride comfort, wear
unevenly, increase stopping distance, and result in sudden deflation (blowout) because they are
more likely to become punctured or damaged by road debris, potholes etc. Symbol messages

Notes If any of the following lamps in the instrument
cluster fails to come on during the bulb self-
check when switching on the ignition, have
the respective bulb checked and replaced if
necessary.
When you switch on the ignition, all lamps in
the instrument cluster come on. The high-

signal indicator lamps will only come on if
activated. If a lamp in the instrument cluster
fails

to come on when the ignition is switched

Warning!
Each tire, including the spare (if provided),
should be checked at least once a month
when cold and inflated to the inflation
pressure recommended by the vehicle
manufacturer on the Tire and Loading
Information placard on the driver’s door B-
pillar
or the tire inflation pressure label on the
inside of the fuel filler flap. If your vehicle has
tires of a different size than the size indicated
on the Tire and Loading Information placard
or the tire inflation pressure label, you should
determine the proper tire inflation pressure
for those tires.
As an added safety feature, your vehicle has
been equipped with a tire pressure monitoring
system (TPMS) that illuminates a low tire
pressure telltale when one or more of your
tires are significantly underinflated.
Accordingly, when the low tire pressure
telltale illuminates, you should stop and check
your tires as soon as possible, and inflate
them to the proper pressure. Driving on a
significantly underinflated tire causes the tire
to overheat and can lead to tire failure.
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.
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 then
remain 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. Lamp in center console

Safety notes
Your vehicle may be equipped with a TIREFIT
kit or a spare wheel with collapsible tire.
Vehicles

with a TIREFIT kit do not have a spare
wheel.
For information on your vehicle’s equipment,
see “Rims and tires” ( Y page 297).G
Warning!
The dimensions of the spare wheel are
different from those of the road wheels. As a
result, the vehicle handling characteristics
change when driving with a spare wheel
mounted. Adapt your driving style
accordingly.
The spare wheel is for temporary use only.
When driving with a spare wheel mounted,
ensure proper tire inflation pressure and do
not exceed a vehicle speed of 50 mph
(80 km/h).
Contact the nearest authorized Mercedes-
Benz Center as soon as possible to have the
spare wheel replaced with a regular road
wheel.
Never

operate the vehicle with more than one
spare wheel mounted.
Do not switch off the ESP ®
when a spare
wheel is mounted. Preparing the vehicle
X Whenever possible, park the vehicle in a
safe

distance from moving traffic on a hard,
flat surface.
X Turn on the hazard warning flasher.
X Turn the steering wheel so that the front
wheels are in a straight-ahead position.
X Engage the parking brake.
X Shift the automatic transmission into park
position P (manual transmission to 1st or
reverse gear R).
X Turn off the engine.
X Remove the SmartKey from the starter
switch.
X Have any passenger exit the vehicle at a
safe distance from the roadway. Open
doors only when conditions are safe to do
so. Sealing tires with TIREFIT
This section applies to SLK 55 AMG with
Performance Package only.
Small

tire punctures, particularly those in the
tread, can be sealed with TIREFIT.
TIREFIT can be used in ambient temperatures
down to -4‡ (-20†). G
Warning!
TIREFIT is a limited repair device. TIREFIT
cannot be used for cuts or punctures larger
than approximately 0.16 in (4 mm) and tire
damage

caused by driving with extremely low
tire inflation pressure, or on a flat tire, or a
damaged wheel.
Do not drive the vehicle under such
circumstances.
Contact the nearest authorized Mercedes-
Benz Center for assistance or call Roadside
Assistance. Flat tire
