108 Controls in detailLightingManual headlamp mode
The low beam headlamps and the parking
lamps can be switched on and off with the
combination switch.
Automatic headlamp mode
The following lamps switch on and off au-
tomatically depending on the brightness of
the ambient light.
Low beam headlamps
Tail and parking lamps
License plate lamps
Side marker lamps
Turn the combination switch to
positionU.
With the key in steering lock position1
only the parking lamps will switch on
and off automatically.
With the engine is running, the low
beam headlamps, the tail and parking
lamps, the license plate lamps, and the
side marker lamps will switch on and
off automatically.
They will be switched on constantly,
when you switch on the front fog
lamps.
iWith the key removed from the steering
lock and the driver’s door open, a warn-
ing sounds if the parking lamps or low
beam headlamps are switched on
(page 107).
Warning!
G
If the combination switch is set toU
the headlamps may switch off unexpect-
edly when the system senses bright am-
bient light, for example light from
oncoming traffic.
the headlamps will not be automatically
switched on under foggy conditions.
To minimize risk to you and to others, acti-
vate headlamps by turning combination
switch toõ when driving or when traffic
and / or ambient lighting conditions require
you to do so.
In low ambient lighting conditions, only
switch from positionU toõ with the
vehicle at a standstill. Switching
fromUtoõ will briefly switch off the
headlamps. Doing so while driving in low
ambient lighting conditions may result in an
accident.
The automatic headlamp feature is only an
aid to the driver. The driver is responsible for
the operation of the vehicle’s lights at all
times.

156 Controls in detailDriving systemsParktronic* system (Parking assist)
The Parktronic system is an electronic and
designed to assist the driver during park-
ing maneuvers. It visually and audibly indi-
cates the relative distance between the
vehicle and an obstacle.
The Parktronic system is automatically
activated when you switch on the ignition.
The Parktronic system deactivates at
speeds over approximately 10 mph
(15 km / h). At lower speeds the Parktronic
system turns on again.The Parktronic system monitors the sur-
roundings of your vehicle with six sensors
in the front bumper and four sensors in the
rear bumper.
1Sensors located in front bumperWarning!
G
The Parktronic is a supplemental system. It
is not intended to, nor does it replace, the
need for extreme care. The responsibility
during parking and other critical maneuvers
always rests with the driver.
Special attention must be paid to objects
with smooth surfaces or low silhouettes
(e.g. trailer couplings, painted posts, or road
curbs). Such objects may not be detected by
the system and can damage the vehicle.
The operational function of the Parktronic
system can be affected by dirty sensors, es-
pecially at times of snow and ice. See
“Cleaning the Parktronic system sensors”
(page 243).
Interference caused by other ultrasonic sig-
nals (e.g. working jackhammers, car wash,
or the air brakes of trucks) can cause the
system to send erratic indications, and
should be taken into consideration.
Warning!
G
Make sure that no persons or animals are in
the area in which you are maneuvering. You
could otherwise injure them.

326 Technical termsParktronic (Parking assist)*

signals to assist the driver during park-
ing maneuvers.

Drives engine-components (alternator,
AC compressor, etc.) from the engine.
Power train
Collective term designating all compo-
nents used to generate and transmit
motive power to the drive axles, includ-
ing

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.
Restraint system
Seat belts, belt tensioner, airbags and
child seat restraint systems. As inde-
pendent systems, their protective func-
tions complement one another.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.
Shift lock
When the vehicle is parked, this lock
prevents the transmission selector le-
ver from being moved out of positionP
without key turned and brake pedal de-
pressed.
SRS
