System limits
Information
WARNING
The system can react incorrectly or not at
all due to the system limits. There is risk of acci‐
dents or risk of property damage. Observe the
system limits and actively interfere if needed.◀
Speed range
The system is best used on well-constructed
roads. The system is functional at speeds be‐
ginning at approx. 20 mph/30 km/h.
The max. speed that can be set is
85 mph/140 km/h.
Comply with the legal speed limit and safety
distance in every situation when using the sys‐
tem.
Detection range
The detection capacity of the system and the
automatic braking capacity are limited.
Two-wheeled vehicles for instance might not
be detected.
WARNING
The system does not relieve from the per‐
sonal responsibility to correctly assess the traf‐
fic situation. Based on the limits of the system,
it cannot independently react to all traffic situa‐
tions. There is risk of an accident. Adjust the
driving style to the traffic conditions. Watch
traffic closely and actively interfere in the re‐
spective situations.◀
Deceleration
The system also does not decelerate in the fol‐
lowing situations:
▷In case of pedestrians, cyclists or similar
slow road users.
▷For red traffic lights.▷For cross traffic.▷For oncoming traffic.▷Unlit vehicles or vehicles with nonworking
lighting at night.

Malfunction
A Check Control message is displayed if the sys‐
tem fails or was automatically deactivated.
The system may not be fully functional in the
following situations:
▷When an object was not correctly detected.▷In heavy fog, rain, sprayed water or snow‐
fall.
▷In tight curves.▷If the field of view of the camera or the
front windshield are dirty or covered.
▷When driving toward bright lights.▷Up to 20 seconds after the start of the en‐
gine, via the Start/Stop button.
▷During calibration of the camera immedi‐
ately after vehicle delivery.
Cruise control
The concept
The system is functional at speeds beginning at
approx. 20 mph/30 km/h.
It maintains the speed that was set using the
control elements on the steering wheel.
The system brakes on downhill gradients if en‐
gine braking is insufficient.

WARNING
The system does not relieve from the per‐
sonal responsibility to correctly assess the traf‐
fic situation. Based on the limits of the system,
it cannot independently react to all traffic situa‐
tions. There is risk of an accident. Adjust the
driving style to the traffic conditions. Watch
traffic closely and actively interfere in the re‐
spective situations.◀
WARNING
The use of the system can lead to an in‐
creased risk of accidents in the following situa‐
tions:
▷On winding roads.▷In heavy traffic.▷On slippery roads, in fog, snow or rain, or
on a loose road surface.
There is risk of accidents or risk of property
damage. Only use the system if driving at con‐
stant speed is possible.◀

rent speed.
▷If selector lever position N is set.▷When DTC is activated or DSC is deacti‐
vated.
▷When DSC is actively controlling stability.

Information
WARNING
The desired speed can be incorrectly ad‐
justed or called up by mistake. There is risk of
an accident. Adjust the desired speed to the
traffic conditions. Watch traffic closely and ac‐
tively interfere in the respective situations.◀
Maintaining/storing the speed

mum of 5 mph/10 km/h.
The maximum speed that can be set de‐
pends on the vehicle.
▷ or button: pressing it to the resist‐
ance point and holding it there accelerates

PDC Park Distance Con‐
trol
The concept
PDC is a support when parking. When you
slowly approach an object in the rear - or also
in the front of the vehicle if the feature is avail‐
able - then the object is reported through:
▷Signal tones.▷Visual display.
General information
Ultrasound sensors in the bumpers measure
the distances from objects.
The maneuvering range, depending on obsta‐
cles and environmental conditions, is approx.
6 ft/2 m.
An acoustic warning is first given with the fol‐
lowing circumstances:
▷By the front middle sensors and the two
corner sensors at approx. 24 inches/60 cm.
▷By the rear middle sensors at approx.
5 ft/1.50 m.
▷When a collision is imminent
Information
Loud noises from outside and inside the vehicle
may prevent you from hearing the PDC's signal
tone.
WARNING
The system does not relieve from the per‐
sonal responsibility to correctly assess the traf‐
fic situation. There is risk of an accident. Adjust
the driving style to the traffic conditions. Watch
traffic and vehicle surroundings closely and ac‐
tively interfere in the respective situations.◀
WARNING
Due to high speeds when PDC is acti‐
vated, the warning can be delayed due to phys‐
ical circumstances. There is risk of injuries or
risk of property damage. Avoid approaching an
object too fast. Avoid driving off fast while PDC
is not yet active.◀

trol Display before a signal sounds.
A display appears as soon as Park Distance

Information
WARNING
The system can react incorrectly or not at
all due to the system limits. There is risk of acci‐
dents or risk of property damage. Observe the
system limits and actively interfere if needed.◀
Limits of ultrasonic measurement
Ultrasonic measuring might not function under
the following circumstances:
▷For small children and animals.▷For persons with certain clothing, for exam‐
ple coats.
▷With external interference of the ultra‐
sound, for example from passing vehicles
or loud machines.
▷When sensors are dirty, iced over, damaged
or out of position.
▷If cargo protrudes.▷Under certain weather conditions such as
high relative humidity, rain, snowfall, ex‐
treme heat or strong wind.
▷With tow bars and trailer couplings of other
vehicles.
▷With thin or wedge-shaped objects.▷With moving objects.▷With elevated, protruding objects such as
ledges or cargo.
▷With objects with corners and sharp edges.▷With objects with a fine surface structure
such as fences.
▷For objects with porous surfaces.
Low objects already displayed, for example,
curbs, can move into the blind area of the sen‐
sors before or after a continuous tone sounds.
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 with
ice.
▷When sensors are covered in snow.▷On rough road surfaces.▷On uneven surfaces, such as speed bumps.▷In large buildings with right angles and
smooth walls, for example, in underground
garages.
▷In automatic car washes.▷Through heavy pollution.▷Due to other ultrasound sources, for exam‐
ple, sweeping machines, high pressure
steam cleaners or neon lights.
The malfunction is signaled by a continuous
tone alternating between the front and rear
speakers. As soon as the malfunction due
to other ultrasound sources is no longer
present, the system is again fully functional.

Socket for OBD Onboard
Diagnosis
Information
CAUTION
The socket for Onboard Diagnosis is an
intricate component intended to be used in
conjunction with specialized equipment to
check the vehicle’s primary emissions system.
Improper use of the socket for Onboard Diag‐
nosis, or contact with the socket for Onboard
Diagnosis for other than its intended purpose,
can cause vehicle malfunctions and creates
risks of personal and property damage. Given
the foregoing, the manufacture of your vehicle
strongly recommends that access to the socket
for Onboard Diagnosis be limited to a dealer's
service center or another qualified service cen‐
ter or repair shop or other persons that have
the specialized training and equipment for pur‐
poses of properly utilizing the socket for On‐
board Diagnosis.◀
Position
There is an OBD socket on the driver's side for
checking the primary components in the vehi‐
cle's emissions.
Emissions▷The warning lamp lights up:
Emissions are deteriorating. Have
the vehicle checked as soon as pos‐
sible.
▷The warning lamp flashes under certain cir‐
cumstances:
This indicates that there is excessive misfir‐
ing in the engine.
Reduce the vehicle speed and have the sys‐
tem checked immediately; otherwise, seri‐
ous engine misfiring within a brief period
can seriously damage emission control
components, in particular the catalytic con‐
verter.
