The concept
The vehicle alarm system responds to:
▷Opening of a door, the hood or the trunk lid.▷Movements in the vehicle: interior motion
sensor, refer to page 31.▷When the car's inclination changes, for in‐
stance if an attempt is made to jack it up and
steal the wheels or to raise it prior to towing
away.▷Interruptions in battery voltage.
The alarm system signals unauthorized entry
attempts for a short time by means of:
▷By sounding an acoustic alarm.▷By switching on the hazard warning system.▷By flashing the high beams.Arming and disarming the alarm
system

Tilt alarm sensor
The tilt of the vehicle is monitored.
The alarm system responds in situations such
as attempts to steal a wheel or tow the car.
Interior motion sensor
The interior of the car is monitored up to the
height of the seat cushions. Thus the alarm sys‐
tem is activated together with the interior motion
sensor even if the hardtop is open. An alarm can
be triggered unintentionally by falling objects
such as leaves, refer to Avoiding unintentional
alarms.

High-beam Assistant
The concept
When the lights are switched on, this system
automatically switches the high beams on and
off. The procedure is controlled by a sensor on
the front of the interior rearview mirror. The as‐
sistant ensures that the high beams are
switched on whenever the traffic situation al‐
lows. The driver can intervene at any time and
switch the high beams on and off as usual.
Activating the High-beam Assistant1.Turn the light switch to .2.With the low beams switched on, briefly
push the turn indicator lever in the direction
of the high beam.
The indicator lamp in the instrument
cluster lights up.
When the lights are switched on, the
high beams are switched on and off automati‐
cally.
The system responds to light from oncoming
traffic and traffic driving ahead of you, and to ad‐
equate illumination, e.g., in towns and cities.
Switching the high beams on and off
manually
▷High beams on, arrow 1.▷High beams off/headlamp flasher, arrow 2.
To reactivate the High-beam Assistant, briefly
push the turn indicator lever toward the high
beams.
System limits
Personal responsibility
The High-beam Assistant cannot serve as
a substitute for the driver's personal judgment
of when to use the high beams. Therefore, man‐
ually switch off the high beams in situations
where this is required to avoid a safety risk.◀
The system is not fully functional in situations
such as the following, and driver intervention
may be necessary:▷In very unfavorable weather conditions,
such as fog or heavy precipitation.▷In detecting poorly-lit road users, such as
pedestrians, cyclists, horseback riders and
wagons; when driving close to train or ship
traffic; and at animal crossings.▷In tight curves, on hilltops or in depressions,
in cross traffic or half-obscured oncoming
traffic on freeways.▷In poorly-lit towns and cities and in the pres‐
ence of highly reflective signs.▷At low speeds.▷When the windshield in front of the interior
rearview mirror is fogged over, dirty or cov‐
ered with stickers, etc.
Sensor view field
The view field of the sensor is located on the
front of the interior rearview mirror.
Do not cover this area with stickers, etc.
Clean the view field, refer to page 185.
Instrument lighting
The parking lamps or low beams must be
switched on to adjust the brightness.

Park Distance Control PDC
The concept
PDC supports you when parking.
Objects in front of or behind your vehicle that
you are approaching slowly are indicated by
acoustic signals.
Measurement
Measurements are made by ultrasound sensors
in the bumpers.
The range is approx. 6 ft/2 m.
An acoustic warning is first given:▷By the front sensors and two rear corner
sensors at approx. 24 in/60 cm.▷By the rear middle sensors at approx. 5 ft/
1.50 m.
System limits
Check the traffic situation as well
PDC cannot serve as a substitute for the
driver's personal judgment of the traffic situa‐
tion. Check the traffic situation around the vehi‐
cle with your own eyes. Otherwise, an accident
could result from road users or objects located
outside of the PDC detection range.
Loud noises from outside and inside the vehicle
may prevent you from hearing the PDC's signal
tone.◀
Avoid driving quickly with PDC
Avoid approaching an object quickly.
Avoid driving away quickly while PDC is not yet
active.
For technical reasons, the system may other‐
wise be too late in issuing a warning.◀
Limits of ultrasonic measurement
The detection of objects can reach the physical
limits of ultrasonic measurement, for instance:▷With tow bars and trailer hitches.▷With thin or wedge-shaped objects.▷With low objects.▷With objects with corners and sharp edges.
Low objects already displayed, e.g., curbs, can
move into the blind area of the sensors before or
after a continuous tone sounds.
High, protruding objects such as ledges may not
be detected.
False warnings
PDC may issue a warning under the following
conditions even though there is no obstacle
within the detection range:
▷In heavy rain.▷When sensors are very dirty or covered in
ice.▷When sensors are covered in snow.▷On rough road surfaces.▷In large buildings with right angles and
smooth walls, e.g., in underground garages.▷In heavy exhaust.▷Due to other ultrasound sources, e.g.,
sweeping machines, high pressure steam
cleaners or neon lights.
Switching on automatically
Engage reverse gear with the engine running or
the ignition switched on.
Switching off automatically when
driving forward
The system switches off when a certain distance
or speed is exceeded.
Switch on the system again if necessary.

Signal tones
When approaching an object, an intermittent
tone is sounded that indicates the position of the
object. For example, if an object is detected to
the left rear of the vehicle, a signal tone sounds
from the left rear speaker.
The shorter the distance to the object becomes,
the shorter the intervals.
If the distance to a detected object is less than
approx. 12 in/30 cm, a continuous tone is
sounded.
If objects are located both in front of and behind
the vehicle, an alternating continuous signal is
sounded.
The intermittent tone is interrupted after approx.
3 seconds:▷If the vehicle stops in front of an object that
is detected by only one of the corner sen‐
sors.▷If moving parallel to a wall.
The signal tone is switched off:
▷When the vehicle moves away from an ob‐
ject by more than approx. 4 in/10 cm.▷When transmission position P is engaged.
Malfunction
The indicator lamp in the instrument
cluster comes on. PDC has failed.
Have the system checked.
To ensure full operability:
▷Keep the sensors clean and free of ice.▷When using high-pressure washers, do not
spray the sensors for long periods and main‐
tain a distance of at least 12 in/30 cm.Seite 88ControlsDriving comfort88

Residual heat
The heat stored in the engine is used to heat the
interior.
This function can be switched on
using the right-hand button under
the following conditions:▷Up to 15 minutes after switching off the en‐
gine.▷When the engine is warm.▷With sufficient battery voltage.▷At an external temperature under 77 ℉/

recirculated air mode
Switch on the desired operating
mode by pressing this button re‐
peatedly:
▷LED off: outside air flows in
continuously.▷Left LED on, automatic recirculated air con‐
trol: a sensor detects pollutants in the out‐
side air. If necessary, the system blocks the
supply of outside air and recirculates the in‐
side air. As soon as the concentration of pol‐
lutants in the outside air has decreased suf‐
ficiently, the system automatically switches
back to outside air supply.▷Right LED on, recirculated air mode: the
supply of outside air into the vehicle is per‐
manently blocked. The system then recir‐
culates the air currently within the vehicle.
Only use recirculated air mode for a limited
period
If condensation starts to form on the inside win‐
dow surfaces during operation in the recircu‐
lated air mode, you should switch it off while also
increasing the air flow rate as required. The re‐
circulated air mode should not be used for an
extended period of time, as the air quality inside
the vehicle deteriorates steadily.◀
