Risk of accident
ABS (Anti-lock Brake System) is
deactivated due to a fault. There-
fore, ESP ®
(Electronic Stability
Program), BAS (Brake Assist), the
steering assistant STEER CON-
TROL, the hill start assist and the
tyre pressure loss warning sys-
tem are also deactivated.
The brake system continues to
function normally, but without
electronic support. The wheels
could therefore lock if you brake
hard.
If the ABS control unit is faulty,
other systems may also not be
available: e.g. Parktronic sys-
tem*, the navigation system* or
the Autotronic*. X
Drive on carefully.
X Observe the additional messages in the multi-function display

Switch off consumers that are not required, e g. reading lamps or
interior lighting.
ABS will be available again as soon as the vehicle's electrical sys-
tem voltage increases. Practical advice

wheel* (Y page 201)
R a spare wheel* (Y page 201)
R the MOExtended run-flat sys-
tem* (Y page 262) Preparing the vehicle
i Vehicle preparation is not necessary on

X Stop your vehicle as far away from traffic
as possible on solid, non-slippery, level
ground.
X Switch on the hazard warning lamps.
X Apply the handbrake.
Vehicles with manual transmission X
Shift to either first or reverse gear. Vehicles with AUTOTRONIC* X
Move the selector lever to P.
For all vehicles X
All occupants must get out of the vehicle.
Make sure that they are not endangered as
they do so.
X Make sure that no one is near the danger
area whilst a wheel is being changed. Any-
one who is not directly assisting in the
wheel change should, for example, stand
behind the barrier.
X Switch off the engine.
X Remove the key from the ignition lock.
X Get out of the vehicle.
X Close the driver’s door.
X Place the warning triangle (Y page 200) at

You can use the TIREFIT kit to seal small
punctures, particularly those in the tyre tread.
You can use TIREFIT in outdoor temperatures
down to -20 °C. G
Risk of accident
In the following situations, your safety is at
particular risk and tyre sealant is unable to
provide breakdown assistance:
R if there are cuts or punctures in the tyre
greater than 4 mm
R if the wheel rim is damaged
R if you have driven at very low tyre pres-
sures or on a flat tyre
Do not drive any further. Consult a qualified
specialist workshop which has the neces-
sary specialist knowledge and tools to carry
out the work required.
Mercedes-Benz recommends that you use
a Mercedes-Benz Service Centre for this
purpose. In particular, work relevant to
safety or on safety-related systems must be
carried out at a qualified specialist work-
shop. Practical advice

i If TIREFIT leaks out, allow it to dry. It can
then be removed like a layer of film.
If you get TIREFIT on your clothing, have it
cleaned as soon as possible with perchloro-
ethylene. G
Risk of injury
Comply with the manufacturer's safety
instructions shown on the sticker on the
electric air pump. i
Your vehicle may be equipped with one of
two different air pumps. Version 1 can be
