Bar
(page 355)
BAS
(Brake A
ssist S

page 355)
Bi-Xenon headlamps*
Headlamps which use an electric arc as
the light source and produce a more in-
tense light than filament headlamps.
Bi-Xenon headlamps produce low
beam and high beam.
CAC

ter, which can help you with any ques-
tions about your vehicle and provide
assistance in the event of a break-
down.

Data bus network serving to control ve-
hicle functions such as door locking or
windshield wiping.Cockpit
All instruments, switches, buttons and
indicator/warning lamps in the passen-
ger compartment needed for vehicle
operation and monitoring.

(
page 355)
COMAND
(Cockpit M
anagement and D
ata Sys-
tem)
Information and operating center for
vehicle sound and communications
systems, including the radio and the
navigation system, as well as other op-
tional equipment (CD changer*, tele-
phone, 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.

489 Technical terms
Head-thorax air bag
Installed in the driver and the front pas-
senger seat, these air bags protect oc-
cupants during side impact collisions
exceeding a preset threshold. Unlike
normal side impact air bags,
head-thorax air bags are also designed
to provide protection for the head area.
Instrument cluster
The displays and indicator/warning
lamps in the driver’s field of vision, in-
cluding the tachometer, speedometer,
coolant temperature indicator and fuel
display.
KEYLESS-GO*
System for entering and operating the
vehicle without the use of a SmartKey.
Kickdown
Depressing the accelerator past the
point of resistance shifts the transmis-
sion down to the lowest possible gear.
This very quickly accelerates the vehi-
cle and should not be used for normal
acceleration needs.Kilopascal (kPa)
(
page 356)
Locking knob
Knob on the door which indicates
whether the door is locked or un-
locked. Pushing the locking knob down
on the driver’s or passenger door from
inside will lock that door.
Maintenance System (U.S. vehicles)
Maintenance service indicator in the
multifunction display that informs the
driver when the next vehicle mainte-
nance service is due. The Maintenance
System in your vehicle tracks distance
driven and the time elapsed since your
last maintenance service, and calls for
the next maintenance service
accordingly.

Memory function*
Used to store three individual seat,
steering wheel and exterior mirror
positions.
Menu
The control system displays are ar-
ranged in menus. Each menu contains
a number of commands for particular
systems.
MON
(Motor O
ctane N
umber)
The Motor Octane Number for gasoline
as determined by a standardized meth-
od. It is an indication of a gasoline's
ability to resist undesired detonation
(knocking). The average of both the
MON (Motor Octane Number) and
->RON (Research Octane Number) is
posted at the pump, also known as
ANTI-KNOCK INDEX.

490 Technical termsMOE
(M
ercedes-Benz O
riginal E
xtended
equipment tires)
Tires with limited run-flat characteris-
tics. The MOExtended system allows
you to continue driving your vehicle
even if there is a total loss of pressure
in one or more tires.
Multifunction display
Display field in the speedometer used
to present information provided by the
control system.
Multifunction steering wheel
Steering wheel with buttons for operat-
ing the control system.
Normal occupant weight
(
page 356)
OCS
(Occupant C
lassification S
ystem)
The system automatically turns the
front passenger front air bag on or off
based on the classified occupant size
category determined by weight sensor
readings from the seat.Overspeed range
Engine speeds within the red marking
on 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.
Poly-V-belt drive
Drives engine-components (alternator,
AC compressor, etc.) from the engine.
Power train
Collective term designating all
components used to generate and
transmit motive power to the drive
axles, including

clutch/torque converter


transmission


transfer case


drive shaft


differential

Program mode selector switch
Used to switch the automatic transmis-
sion between regular operationS and
comfort operationC.
CLK 55 AMG with steering wheel gear-
shift control and manual shift program:
In addition toS andC (for regularS or
comfortC operation, see above) you
can use theM for manual shift
program.
PSI
(Pounds per S
quare I
nch)
(
page 356)
Recommended tire inflation pressure
(page 356)
REST*
(Residual engine heat utilization)
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.

491 Technical terms
Restraint systems
Seat belts, child restraints, lower an-
chors and tethers for children (LATCH).
As independent systems, their protec-
tive functions complement one anoth-
er.
Rim
(
page 356)
Roll bars
Occupant protection system which
consists of tubular steel, integrated in
the rear head restraints. The roll bars
are lowered into the car body during
normal driving conditions and raised
automatically in an accident or in a crit-
ical driving situation.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
ANTI-KNOCK INDEX.
RFI*
(R
un F
lat I
ndicator)
The Run Flat Indicator monitors the set
tire inflation pressures by evaluating
each wheel’s rotational speed. If a
wheel’s rotational speed changes due
to falling tire inflation pressure, a corre-
sponding warning message appears in
the multifunction display.Shift lock
When the vehicle is parked, this lock
prevents the gear selector lever from
being inadvertently moved out of
positionP without SmartKey turned
and brake pedal depressed.
Sidewall
(
page 356)
Soft top
Soft top roof that can be opened by
pulling and closed by pressing a switch
and stored in the soft top compartment
in the trunk area.
SRS
(Supplemental R
estraint S
ystem)
Air bags, air bag control unit (with
crash sensor), emergency tensioning
device. Though independent systems,
they are closely interfaced to provide
effective occupant protection.

You can change the gears yourself with
the steering wheel gearshift buttons.
