Emergency spare wheel Narrow spare wheel which is lighter
and takes up less space than a full-
sized spare wheel.
EN 228 European standard for unleaded petrol.
Engine control system Controls the various engine functions,
e.g. the engine speed.
Engine number Number determined by the manufac-
turer and marked on the cylinder
crankcase, by which each engine can
be clearly identified.
Engine oil viscosity Measure of the internal oil friction (vis-
cosity) at different temperatures. The
higher the temperature the oil can tol-
erate without thinning too much, or the
lower the temperature it can tolerate
without thickening too much, the bet-
ter the viscosity characteristics of the
oil. ESP
(E le
ctronic S tability P ro
gram)

tion when cornering and in emergency
situat ions, e.g. when there is a risk of
skidding.
GPS (G lo
ba l P ositioning S ystem)
Syste mfor determining geographical
location. A GPS unit located in the vehi-
cle receives satellite signals, compares
them to a digital map (e.g. on CD ROM)
and uses them to det ermine the posi-
tion of the vehicle and for navigation
pur poses.
GSM (G lo
ba l S ystem for M obile Communica-
tions)

that provided by the sidebag.

hicle load, so that onco ming traffic is
not dazzled.
Heat erbooster system
Provides additional heat in the vehicle
interior on vehicles with a diesel en-
gine.
Instrum ent cluster
Displays and indicator lamps in the

trolled self-ignition of th egas-air mix-
ture in the cylinder head (knocking).

tane number, the higher the knock re-
sistance.

er)

ing wheel and mirror positions. Posi-
tions are saved for each key and/or

mands. You can change the settings for
your vehicle directly using these com-
mands. Minispare

sages.

Steering wheel with buttons which you
use to contro lthe ->operating system.
On-board voltage
The vehicle's voltage, influenced by
outgoing lines, electrical consumers
and return lines. The battery can re-
ceive and produce extremely high elec-
tric alcurrent without causing a
significant change in the voltage. Operating system
You can use the operating syst emto
look up information about your vehicle
and to make settings. This information
is displayed on the ->multi-function dis-
play. The buttons on the ->multi-func-
tion steering wheel are used to control
the displ ayand the settings in the oper-
at ing system.
Overrevving range Speeds in the red area of the rev coun-
ter at which the engine can only oper-
ate for a shor tperiod.
Overrun mode Passive acceleration (deceleration) of
the vehicle, e.g. if you drive downhi llor
release the accelerator pedal.

sion*, switch used to shift between

tolower rotation speeds at the drive
wheels and thus optimises the transfer
of engine ->torque to the wheels.
