Tire and loading terminology
Accessory weight
The combined weight (in excess of those
standard items which may be replaced) of
automatic transmission, power steering,
power brakes, power windows, power
seats, radio, and heater, to the extent that
these items are available as
factory-installed equipment (whether
installed or not).
Air pressure
The amount of air inside the tire pressing
outward on each square inch of the tire.
Air pressure is expressed in pounds per
square inch (psi), or kilopascal (kPa) or
bars.
Aspect ratio
Dimensional relationship between tire
section height and section width
expressed in percentage.Bar
Another metric unit for air pressure. There
are 14.5038 pounds per square inch (psi)
to 1 bar; there are 100 kilopascals (kPa)
to 1 bar.
Bead
The tire bead contains steel wires wrapped
by steel cords that hold the tire onto the
rim.
Cold tire inflation pressure
Tire inflation pressure when your vehicle
has been sitting for at least three hours or
driven no more than one mile (1.6 km).
Curb weight
The weight of a motor vehicle with stan-
dard equipment including the maximum
capacity of fuel, oil, and coolant, and, if so
equipped, air conditioning and additional
optional equipment, but without passen-
gers and cargo.

iIf the vehicle is not be used for a longer
period of time, do not disconnect the
consumer battery. Instead, maintain
the condition of the battery by using
the battery charger approved by
Mercedes-Benz for use on the SLR and
supplied with the car (
page 358).
This charger automatically controls the
charge rate, and can be left connected
to the car for long periods without dam-
age to the battery.
If the battery supplying the vehicle’s
electrical consumers is disconnected,
the days of disconnection will not be in-
cluded in the count shown by the ser-
vice indicator. To arrive at the true
service deadline, you will need to sub-
tract these days from the days shown
in the service indicator.
Do not confuse the maintenance
service indicator with the engine oil
level indicator:.

Problem
Possible cause/consequence
Suggested solutions
-
The yellow ABS indicator
lamp comes on while driving.
The ABS has detected a malfunction and
has switched off. The BAS and the ESP
®
are also switched off (see messages in dis-
play).
The electrohydraulic brake system is still
functioning normally but without ABS
available.
If the ABS control unit is malfunctioning
the automatic transmission may also be
malfunctioning.

Continue driving with added caution. Wheels
may lock during hard braking, reducing
steering capability.

Read and observe messages in the multi-
function display (
page 307).

Have the system checked at an authorized
Mercedes-Benz Center immediately.
Failure to follow these instructions increases
the risk of an accident.
The charging voltage has fallen below
10 volts and the ABS was switched off.
When the voltage is above this value again, the
ABS is operational again.
If necessary, have the generator and battery
checked.

the ability to steer or brake the vehicle. You
may lose control of the vehicle.
Continued driving with a flat tire will cause
excessive heat build-up and possibly a fire.
Warning!
G
Have worn or damaged tires replaced in
pairs (front pair or rear pair) an make sure
the tires rotate in the direction specified
(page 257). Otherwise, the driving stabili-
ty of the vehicle will be adversely affected,
especially when driving at high speeds.
