The tire pressure is being checked.
TIRE PRES. MONITOR
NOT ACTIVE
The tire inflation pressure monitor* is un-
able to monitor the tire pressure due to

the presence of several wheel sensors
in the vehicle.


excessive wheel sensor tempera-
tures.


a nearby radio interference source.


unrecognized wheel sensors mount-
ed.

Check the tire pressure at the next ser-
vice station.
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 current
pressure values as the basis for monitoring.
TIRE PRES. MONITOR
CURRENTLY
UNAVAILABLE
The tire pressure monitor is temporarily inop-
erative because:

an additional wheel sensor is in the vehi-
cle


the maximum temperature of the wheel
sensor has been exceeded


a radio source is causing interference


unrecognized wheel sensors have been
installed

Remove any additional wheel sensors
from the vehicle
As soon as the causes of the malfunction
have been removed, the tire inflation
pressure monitor automatically becomes
active again.
TIRE PRES. MONITOR
NOT OPERATIONAL
DRIVE TO WORKSHOP
The tire pressure monitor or a wheel sensor
is malfunctioning.

Have the tire inflation pressure moni-
tor checked by an authorized
Mercedes-Benz Center.
A wheel without proper sensor was installed.

Have the wheels checked.

384 Technical termsCOMAND
(C
ockpit M
anagement and D
ata Sys-
tem)
Information and operating center for
vehicle sound and communications
systems, including the radio and navi-
gation system, as well as other optional
equipment (CD changer, telephone,
etc.).
Control system
The control system is used to call up
vehicle information and to change
component settings. Information and
messages appear in the multifunction
display. The driver uses the buttons on
the multifunction steering wheel to
navigate through the system and to ad-
just settings.
Cruise control
A 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 placed 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
(E
lectronic S
tability Pr
ogram)
Improves vehicle handling and direc-
tional stability.
ETD
(E
mergency T
ensioning D
evice)
Device which deploys in certain frontal
and rear collisions exceeding the sys-
tem's threshold to tighten the seat
belts.
->SRS

387 Technical terms
RON
(R
esearch O
ctane N
umber)
The Research Octane Number for gaso-
line as determined by a standardized
method. It is an indication of a gaso-
line's ability to resist undesired detona-
tion (knocking). The average of both
the ->MON (Motor Octane Number)
and RON (Research Octane Number) is
posted at the pump, also known as AN-
TI-KNOCK INDEX.
Shift lock
When the vehicle is parked, this lock
prevents the transmission selector le-
ver from being inadvertently moved out
of positionP without SmartKey turned
and brake pedal depressed.
Speedshift
Steering wheel gearshift control and
manual shift program. In the manual
shift program mode you can change
the gears yourself on the steering
wheel or by using the selector lever. SRS
(S
upplemental R
estraint S
ystem)
Seat belts, emergency tensioning de-
vice and airbags. Though independent
systems, they are closely interfaced to
provide effective occupant protection.
Tele Aid System
(T
elematic A
larm I
dentification on D
e-
mand)
The Tele Aid system consists of three
types of response: automatic and man-
ual emergency, roadside assistance
and information. Tele Aid is initially ac-
tivated by completing a subscriber
agreement and placing an acquain-
tance call.
The Tele Aid system is operational pro-
vided that the vehicle’s battery is
charged, properly connected, not dam-
aged and cellular and GPS coverage is
available.Telematics
A combination of the terms “telecom-
munications” and “informatics”.
Tightening torque
Force times lever arm (e.g. a lug
wrench) with which threaded fasteners
such as wheel bolts are tightened.
Tire speed rating
Part of tire designation; indicates the
speed range for which a tire is ap-
proved.
Traction
Force exerted by the vehicle on the
road via the tires.
VIN
(V
ehicle I
dentification N
umber)
The number set by the manufacturer
and placed on the body to uniquely
identify each vehicle produced.
Voice control system*
Voice control system for car phones,
portable cell phones and audio sys-
tems (radio, CD, etc.).
