COMAND
(C
ockpit Management and Data
System)
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.
Differential locks
On slippery surfaces, differential locks
prevent one wheel of an axle from spin-
ning while the other wheel stands still,
resulting in driving force no longer be-
ing transferred.Cruise control
Driving convenience system that auto-
matically maintains the vehicle speed
set by the driver.

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 Stability Program)
Improves vehicle handling and direc-
tional stability.
ETD
(E
mergency Tensioning Device)
Device which deploys in certain frontal
and rear collisions exceeding the sys-
tem’s threshold to tighten the seat
belts.
->SRS
FSS (Canada vehicles)
(F
lexible Service System)
Maintenance service indicator in the
speedometer display that informs the
driver when the next vehicle mainte-
nance service is due. FSS evaluates en-
gine temperature, oil level, vehicle
speed, engine speed, distance driven
and the time elapsed since your last
service, and calls for the next mainte-
nance service accordingly.

MON
(M
otor Octane Number)
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.
Multifunction display
A display field in the instrument cluster
used to present information provided
by the control system.
Normal occupant weight
(
page 274)Overspeed range

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 system
Seat belts, belt tensioner, airbags and
child seat restraint systems. As inde-
pendent systems, their protective func-
