TIRE PRES., RR
CAUTION, TIRE DEFECT!
The right rear tire is deflating.
Carefully bring the vehicle to a halt,
avoiding abrubt steering and braking
maneuvers.
Change the wheel (
page 361).
TIRE PRES., RR
CHECK TIRES!
The right rear tire pressure is low.
Carefully bring the vehicle to a halt.
Check the tire pressure.

TIRE PRES., LR
CAUTION, TIRE DEFECT!
The left rear tire is deflating.
Carefully bring the vehicle to a halt,
avoiding abrupt steering and braking
maneuvers.

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.

TIRE PRES. MONITOR
REACTIVATED
The tire pressure monitor is using the cur-
rent pressure values as the basis for mon-
itoring.
TIRE PRES. MONITOR
CURRENTLY
UNAVAILABLE
The tire inflation pressure monitor* is un-
able to monitor the tire pressure due to:
the presence of several wheen sen-
sors in the vehicle
excessive wheel sensor temperatures
a nearby radio interference source
unrecognized wheel sensors installed
Remove any extra wheel sensors from the
vehicle
As soon as the causes of the malfunction
have been removed, the tire pressure moni-
tor automatically becomes active again.
TIRE PRES. MONITOR
NOT OPERATIONAL
DRIVE TO WORKSHOP
The tire pressure monitor or a wheel sen-
sor is malfunctioning.
Have the tire inflation pressure monitor
checked by an authorized Mercedes-Benz
Center.
A wheel without proper sensor was in-
stalled.
Have the wheels checked.
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-

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.

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.
