BATTERY/ALTERNATOR
VISIT WORKSHOP!
The battery was charged with a battery
charger or jump started.

Have the battery checked at a ser-
vice station.
The battery is no longer charging.
Possible causes:

Alternator malfunctioning


Broken poly-V-belt
Do not forget that the brake system re-
quires electrical energy and may be operat-
ing with restricted capability. Considerably
greater brake pedal force is required and
the stopping distance is longer.

Stop immediately and check the
poly-V-belt.
If it is broken:

Do not continue to drive. Otherwise
the engine will overheat due to an in-
operative water pump which may re-
sult in damage to the engine. Notify
an authorized Mercedes-Benz
Center.
If it is intact:

Drive immediately to the nearest au-
thorized Mercedes-Benz Center. Ad-
just driving to be consistent with
reduced braking responsiveness.

the engine will overheat due to an in-
operative water pump which may re-
sult in damage to the engine. Notify

Center.
If it is intact:

Do not continue to drive the vehicle
with this message displayed. Doing
so could result in serious engine
damage that is not covered by the
Mercedes-Benz Limited Warranty.

Warning!
G
Do not drive with a flat tire. A flat tire affects
the ability to steer or brake the vehicle.
You may lose control of the vehicle. Contin-
ued driving with a flat tire will cause exces-
sive heat build-up and possibly a fire.

just settings.
Cruise control
Driving convenience system for auto-
matically maintaining the vehicle speed
set by the driver.Distronic*
A driving convenience cruise control
system which helps the driver maintain
a pre-selected speed:


If there is no vehicle directly ahead,
the system operates in the same
way as conventional ->cruise con-
trol.


If a slower moving vehicle is ahead,
Distronic will reduce your vehicle
speed to the extent permitted by re-
duced throttle and up to 20% brak-
ing power to maintain the preset
minimum following distance.
Engine number
The number set by the manufacturer
and stamped on the cylinder block to
uniquely identify each engine pro-
duced.Engine oil viscosity
Measurement for the inner friction (vis-
cosity) of the oil at different tempera-
tures. The higher the temperature an
oil can tolerate without becoming thin,
or the lower the temperature it can tol-
erate without becoming viscous, the
better the viscosity.
ESP

ing the control system.
Overspeed range
Engine speeds within the red marking
of the tachometer dial. Avoid this en-
gine speed range, as it may result in se-
rious engine damage that is not
covered by the Mercedes-Benz Limited
Warranty.

Feature that uses the engine heat
stored in the coolant to heat the vehi-
cle interior for a short time after the en-
gine has been turned off.
Restraint systems
Seat belts, belt tensioners, airbags and
child restraint systems. As indepen-
