2008 MERCEDES-BENZ A-CLASS HATCHBACK warning

Flat tyre

X
Fold up the warning triangle and stow it
away.
X Pull away immediately.
This distributes the TIREFIT more evenly
around the tyre.
X Stop after driving for approximately ten
minutes and check the tyre pressure with
the electric air pump. G
Risk of accident
If the tyre pressure is now lower than
1.3 bar, the tyre is too badly damaged. 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 rec-
ommends that you use a Mercedes-Benz
Service Centre for this purpose. In particu-
lar, work relevant to safety or on safety-
related systems must be carried out at a
qualified specialist workshop. 9
Pressure release button
a Pressure gauge
X If the tyre pressure is still at least 1.3 bar,
correct it (see fuel filler flap for values).
To increase the tyre pressure: switch on
the electric air pump.
To reduce the tyre pressure: press yellow
pressure release button 9next to pres-
sure gauge a.
X Drive to the nearest workshop and have the
tyre changed there.
X Have the TIREFIT kit replaced as soon as
possible at a qualified specialist workshop,
e.g. at a Mercedes-Benz Service Centre. G
Risk of accident
Do not exceed the maximum speed of
80 km/h.
The "max. 80 km/h "sticker must be affixed
within the driver's field of vision.
The vehicle's handling characteristics may
be affected. H
Environmental note
Have the used TIREFIT kit disposed of pro-
fessionally, e.g. at a Mercedes-Benz
Service Centre.
X Have the TIREFIT kit replaced every four
years at a qualified specialist workshop,
e.g. a Mercedes-Benz Service Centre. Practical advice

ring the vehicle X
Place the ratchet ring spanner onto the
hexagon nut of the jack so that the lettering
AB is visible.
X Lower the vehicle by turning the ratchet
ring spanner until the vehicle is once again
standing firmly on the ground.
X Place the jack to one side. 1
–5 Wheel bolts
X Tighten the wheel bolts evenly in a cross-
wise pattern in the sequence indica-
ted (1 to5). The tightening torque is
130 Nm . G
Risk of accident
Have the tightening torque checked imme-
diately after a wheel is changed. The wheels could work loose if they are not tightened
to a torque of 130 Nm.
X Turn the jack back to its initial position and
store it and the rest of the vehicle tool kit
in the stowage compartment in the luggage
compartment.
i When you are driving with the "Minispare"
emergency spare wheel* fitted, the tyre
pressure loss warning system* cannot
function reliably. MOExtended run-flat system*
The MOExtended run-flat system may only be
used in conjunction with the tyre pressure
loss warning system.
! The maximum permissible distance which
can be driven in run-flat mode depends on
the load in the vehicle. It is 50 km if the
vehicle is partially laden and 30 km if fully
laden.
The maximum range that can be driven in
emergency operation is measured from the
point at which the pressure loss warning
message appears in the multi-function dis-
play. You must not exceed a maximum speed of
80 km/h. G
Risk of accident
The handling characteristics of your vehicle
deteriorate in run-flat mode, for example:
R when cornering
R when braking
R when accelerating rapidly
Adapt your driving style accordingly and
avoid sudden changes in direction and sud-
den acceleration, as well as driving over
obstacles (i.e. kerbs, potholes), and driving
off-road. This is particularly the case when
the vehicle is heavily laden.
The maximum permissible distance that
can be driven in run-flat mode depends to
a large extent on the loads placed on the
vehicle. It can be shorter due to high
speeds, a heavy load, sudden acceleration
and/or manoeuvring, the road surface con-
dition, outside temperature, etc., or further,
if you drive carefully and conservatively.
Do not continue to drive in run-flat mode if:
R you hear banging noises.
R the vehicle starts to shake.
R you see smoke and smell rubber. Practical advice
