G
In the event a malfunction of the SRS is indi-
cated as outlined above, the SRS may not be
operational. For your safety, we strongly
recommend that you visit an authorized
Mercedes-Benz Center immediately to have
the system checked; otherwise the SRS may
not be activated when needed in an
accident, which could result in serious or
fatal injury, or it might deploy unexpectedly
and unnecessarily which could also result in
injury.
Warning!
G
If the level of steering gear oil in reservoir is
too low, the steering power assistance could
fail. Much greater effort will then be needed
to turn the steering wheel.
Do not add steering oil without checking the
steering system.
Do not drive the vehicle. Have the system
checked at your authorized Mercedes-Benz

305 Practical hints
Flat tire
Open flap1 on air pump.
Pull out electrical plug4 and air hose
with the pressure gauge2.
Observe instructions on air pump label.
Remove the valve cap from valve.
Screw the air hose2 on to the tire
valve.
Insert electrical plug4 into vehicle
cigarette lighter socket.
To switch on the air pump turn the
SmartKey in the starter switch to
position1 (
page 31).
Operate air pump until the pressure
gauge displays 36 psi (2.5 bar)
This takes about five minutes for the
space tire. The air hose2 and the
union nut3 can become hot during in-
flation.
To switch off the air pump turn the
SmartKey in the starter switch to
position0 (
page 31).
If the tire pressure is above 36 psi
(2.5 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 air
pump back in the trunk.
!Do not operate the electric air pump
longer than eight minutes without in-
terruption. Otherwise it may overheat.
You may operate the air pump again af-
ter it has cooled off.
Warning!
G
Follow recommended inflation pressures.
Do not overinflate tires. Overinflated 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. Underinfalted tires
wear unevenly, adversely affect handling
and fuel economy, and are more likely to fail
from being overheated.
Do not overload the tires by exceeding the
specified vehicle capacity weight (as indicat-
ed by the label on the driver’s door latch
post). Overloading the tires can overheat
them, possibly causing a blowout.
