2005 MERCEDES-BENZ SLR CLASS warning light

255 Operation
Tires and wheels
Tread depth
Do not allow your tires to wear down too
far. Adhesion properties on wet roads are
sharply reduced at tread depths under 1/8in (3 mm).
Treadwear indicators (TWI) are required by
law. These indicators are located in six
places on the tread circumference and
become visible at a tread depth of approx-
imately
1/16
in (1.6 mm), at which point
the tire is considered worn and should be
replaced.
Recommended minimum tire tread depth:


Summer tires
1/8in (3 mm)


Winter tires
1/6in (4 mm)
1TWI (T

The treadwear indicator appears as a solid
band across the tread.Storing tires

Warning!
G
Although the applicable federal motor safety
laws consider a tire to be worn when the
treadwear indicators (TWI) become visible at
approximately
1/16in (1.6 mm), we recom-
mend that you do not allow your tires
to wear down to that level. As tread depth
approaches
1/8in (3 mm), the adhesion
properties on a wet road are sharply
reduced.
Depending upon the weather and/or road
surface (conditions), the tire traction varies
widely.
!Keep unmounted tires in a cool, dry
place with as little exposure to light as
possible. Protect tires from contact
with oil, grease and gasoline.!Never use a round nozzle to power
wash tires. The intense jet of water can
result in damage to the tire.
Always replace a damaged tire.Warning!
G
Have worn or damaged tires replaced in
pairs (front pair or rear pair). Otherwise, the
driving stability of the vehicle will be ad-
versely affected.

265 Operation
Tires and wheels
Checking tire inflation pressure
electronically
The tire inflation pressure monitor only
functions on wheels that are equipped with
the proper electronic sensors. It monitors
the tire inflation pressure, as selected by
the driver, in all four tires. A warning is is-
sued to alert you to a decrease in pressure
in one or more of the tires.
Tire inflation pressure inquiries are made
using the multifunction display
(page 117). The present inflation pres-
sures are displayed only after a few min-
utes travel time.

Switch on the ignition (
page 40).

Make sure you are viewing the stan-
dard display menu (
page 117).

Press k button until the current in-
flation pressures for each tire appear in
the tachometer display field.
iPossible differences between the read-
ings of a tire inflation pressure gauge of
an air hose, e.g. gas station equipment,
and the vehicle’s control system can
occur. The readings issued by the con-
trol system are more precise.
iYou can select the unit of measure
(bar/psi) used for the tire inflation
pressure by changing the setting in the
control system (
page 136).
Warning!
G
When the tire inflation pressure monitoring
system warning light is lit, one or more of
your tires is significantly under-inflated. You
should stop and check your tires as soon as
possible, and inflate them to the proper tire
inflation pressure as indicated on the vehi-
cle’s tire information placard. Driving on a
significantly under-inflated tire causes the
tire to overheat and can lead to tire failure.
Under-inflation also reduces fuel efficiency
and tire tread life, and may affect the vehi-
cle’s handling and stopping ability. Each tire,
including the spare, should be checked
monthly when cold and set to the recom-
mended tire inflation pressure as specified
in the vehicle placard and owner’s manual.

What to do if ...
Problem
Possible cause
Suggested solutions
<
The red Airbrake warning
lamp comes on while driving
and you hear a warning
sound.
The Airbrake or the central locking system
is malfunctioning.

Notify an authorized Mercedes-Benz Center
immeditaly.
>
The red gearshift indicator
lamp comes on while you are
driving.
You are driving with the manual shift pro-
gram. The engine is in the overrevving
range.

Shift to the next higher gear. Otherwise the
fuel supply will be interrupted to prevent the
engine from overrevving.
A
The yellow reserve fuel warn-
ing lamp lights up while you
are driving.
The fuel level has fallen into the reserve
range.

Refuel at the nearest gas station
(page 240).
=
The engine oil temperature
symbol comes on in the
tachometer while you are
driving.
The engine oil has not yet reached its
operating temperature.

Warm up the engine and do not drive at full
power until the operating temperature has
been reached.
The symbol will go out as soon as the engine
oil has reached its operating temperature.

8Electric air pump switch
9Air hose with pressure gauge and vent
screw
aFiller hose
Unscrew the valve cap from tire
valve7.

Screw filler hosea onto tire valve7.

Insert electrical plug4 into vehicle
cigarette lighter socket.

Turn the SmartKey in the starter switch
to position1 (
page 40).

PressI on electric air pump switch8.
The electric air pump should now
switch on and inflate the tire.After five minutes, the pressure gauge
must display at least 26 psi (1.8 bar). The
air hose can become hot during inflation.
Please exercise appropriate caution.

If this tire inflation pressure is not at-
tained, turn off the electric air pump,
detach the filler hose from the tire
valve, and drive vehicle back and forth
very slowly approximately 30 ft (10 m).
This serves to better distribute the
TIREFIT sealant material inside the tire.

Unscrew the air pump’s air hose5
from flange6 of the TIREFIT
container.

Screw air hose5onto tire valve7.

Inflate the tire again.
Warning!
G
Observe safety instructions on air pump
label.
!Do not operate the electric air pump
longer than six minutes without inter-
ruption. Otherwise it may overheat.
You may operate the air pump again af-
ter it has cooled off.
