Roll bar
G
DANGER
If the roll bar is malfunctioning, the
A Malfunction Service Required
message appears

in the multifunction display.
The roll bars will then possibly not be
extended in the event of an accident. This
could result in severe or even fatal injuries to
you and other occupants. In this case, visit a
qualified specialist workshop immediately
and have the roll bar checked. G
WARNING
If
you place objects or clothing on the roll bar
covers, these

could impair roll bar extension.
You and others could be injured by objects
being thrown around when the roll bars are
triggered.
Ensure that the area above the roll bar covers
is kept clear. Stow objects or clothing in a
secure place. The roll bars are located in the rear area of
the vehicle under the two outer rear
compartment trim covers.
The roll bars are extended automatically if
systems detect that the vehicle is in danger
of rolling over. The two rear compartment
trim covers are opened and the roll bars are
extended within fractions of a second.
Once the roll bars are extended, you can no
longer lower them. An open roof can no
longer
be

closed. In this case, visit the nearest
qualified specialist workshop. Occupant Classification System
(OCS)
Method of operation G
WARNING
If the 4
PASSENGER AIR BAG OFF
indicator lamp illuminates when an adult or
someone larger than a small individual is in
the front-passenger seat, have the front
passenger reposition

himself or herself in the
seat until the 4 PASSENGER AIR BAG OFF
indicator lamp goes out.
In the event of a collision, the air bag control
unit will not allow front-passenger front air
bag and front-passenger knee bag
deployment when the OCS has classified the
front-passenger occupant as weighing as
much as or less than a typical 12 month old
child in a standard child restraint or if the
front-passenger seat is classified as being
unoccupied.
When the OCS senses that the front-
passenger seat occupant is classified as
being up to or less than the weight of a typical
12-month-old child in a standard child
restraint, the 4 PASSENGER AIR BAG OFF
indicator lamp will illuminate when the engine
is started and remain illuminated. This
indicates that the front-passenger front air
bag and the front-passenger knee bag are
deactivated.
When the OCS senses that the front-
passenger seat is classified as being empty,
the 4 PASSENGER AIR BAG OFF indicator
lamp will illuminate when the engine is started
and remain illuminated. This indicates that
the front-passenger front air bag and the
front-passenger knee bag are deactivated.
When the OCS senses that the front-
passenger seat occupant is classified as
being heavier than the weight of a typical 12-
month-old child seated in a standard child
restraint or as being a small individual (such
as a young teenager or a small adult), the
4 PASSENGER AIR BAG OFF indicator
lamp will illuminate for approximately 6 Occupant safety

X Turn the SmartKey to position 1 in the
ignition lock (Y page 135).
X Press on/off switch = on the tire inflation
compressor to I.
The tire inflation compressor is switched
on. The tire is inflated.
i First, tire sealant is pumped into the tire.
The pressure can briefly rise to
approximately 500 kPa (5.0 bar/73 psi).
Do not switch off the tire inflation
compressor during this phase.
X Allow the tire inflation compressor to run
for five minutes. The tire should then have
attained a pressure of at least 180 kPa
(1.8 bar/26 psi).
If

a tire pressure of 180 kPa (
1.8 bar/26 psi)
has been attained after five minutes:
(Y page 512).
If a tire pressure of 180 kPa (1.8 bar/26 psi)
has not been attained after five minutes:
(Y page 512).
i If tire sealant leaks out, allow it to dry. It
can then be removed like a layer of film.
If your clothes are soiled with tire sealant,
have them cleaned with perchloroethylene
at a dry cleaner as soon as possible.
Tire pressure of at least 180 kPa
(1.8 bar/26 psi) is not reached If a pressure of 180 kPa
(
1.8 bar/26 psi) has
not been achieved after five minutes:
X Switch off the tire inflation compressor.
X Unscrew the filler hose from the valve of
the faulty tire.
X Very slowly drive forwards or reverse
approximately 30 ft

(10 m).
X Pump up the tire again.
After a maximum of five minutes the tire
pressure must

be at least 180 kPa (1.8 bar/
26 psi). G
WARNING
If the required tire pressure is not reached
after the specified time, the tire is too badly
damaged. The tire sealant cannot repair the
tire in

this instance. Damaged tires and a tire
pressure that is too low can significantly
impair the vehicle's braking and driving
characteristics. There is a risk of accident.
Do not continue driving. Contact a qualified
specialist workshop.
Tire pressure of 180 kPa (1.8 bar/
26 psi) is reached G
WARNING
A tire temporarily sealed with tire sealant
impairs the driving characteristics and is not
suitable for higher speeds. There is a risk of
accident.
You should therefore adapt your driving style
accordingly and

drive carefully. Do not exceed
the specified maximum speed with a tire that
has been repaired using tire sealant.
! Residue from the tire sealant may come
out of the filler hose after use. This could
cause stains.
Therefore, place the filler hose in the plastic
bag which contained the TIREFIT kit. H
Environmental note
Have the used tire sealant bottle disposed of
professionally, e.g. at a qualified specialist
workshop.
X Switch off the tire inflation compressor.
X Unscrew the filler hose from the valve of
the faulty tire.
X Stow the tire sealant bottle and the tire
inflation compressor.
X Pull away immediately.
The maximum speed for a tire sealed with
tire sealant

is 50 mph (80 km/h). The "max.
80 km/h" sticker must be affixed to the 512
Flat tire
