you switch on the ignition. PTS is deacti-
va ted when the speed exceeds 15 km /h.
The Parktronic system is reactivated when
the vehicle's speed falls below this.
PTS monitors the area around your vehicle
using six sensors in the front bumper and
four sensors in the rear bumper.

Ve hicle el ectron ics
! Only have th eengine electronics and asso-
ciated parts, such as control units, sensors or
connec tor leads, serviced at a qualified spe cial-
is tworkshop. Otherwise, vehicle parts may wear
more quickly and the vehicle warranty and gen-
eral operating permit may be invalidated. Electrical and electronic equipment can
jeopardise the operational safety of your
vehicle. If equipment of th iskind is retrofit-
te d, it must be typ eappro vedand must
bear the emark .The emark can be ob-
tained from the equipment manufacturer
or an authorised testing authority.
If you wish to install telephones or two-way
radios in the vehicle, you must obtain for-
mal approval. Mercedes-Benz approves
the installation of mobile telephones and
two-w ayradios provide dthat they are in-
stalled professionally and a low-reflection
exterior aerial is used.
The transmission output of the telephone
or two-way radio must not exceed the max-
imum transmission outputs specif ied on
the next page. Vehicle electronics

On vehicles with ->automatic transmis-
sion*, the transmission is shifted down
to a lower gear when the accelerator
ped alis depressed beyond the pres-
sure point. This increases the rate of
vehicle acceleration. Knock
resistance
Resistance of petrol against uncon-
trolled self-ignition of th egas-air mix-
ture in the cylinder head (knocking).
The octane number is a measure of
knock res istance. The higher the oc-
tane number, the higher the knock re-
sistance.
Lamp Spreads and forms the beam of light
from a ->bulb, e.g. headlamps.
LED (L ig
ht -E mitting D iode);
Semiconductor element that converts
electr icity directly into light.
Light emitting diode
->LED Light sensor
Detects ambient light conditions to
contro lwhether the following lamps
should be switched on and off automat-
ically:

! Side lamps
! Licence plate lighting
LI M indicator lamp
(Lim it
er)

! You can raise and lower the roll-
over bars manually.
RON (R esearch O ctane N umber)
Indicates the petrol octane num ber de-
ter mined bystan dard methods. RONis
a measure of the ->knock resistance of
the petrol. The RON is approximately
te n points higher than the ->MON. 209en_d2.boo Seite
