General information
Within system limits, the exit warning system
can detect traffic approaching from behind such
as vehicles, and provide assistance based on this
information when you are exiting the vehicle
> fig. 127. The system uses the data from the ra-
dar sensors at the rear corners of the vehicle.
Displays and warnings
If a door is opened while the vehicle is stationary,
the warning strip @ on that door and the display
@ on that side of the vehicle will blink if another
road user is detected in a critical situation, If an-
other road user that is classified as critical is ap-
proaching while a door is already open, the dis-
plays on that door will turn on.
The same messages apply for the exit warning
system and side assist > page 145.

-Z\ WARNING
— Follow the safety precautions and note the
limits of the assist systems, sensors, and
cameras > page 114.
— Always pay attention to traffic and to the
area around your vehicle. The exit warning
system does not replace the attention of the
vehicle occupants. The vehicle occupants are
always responsible for opening the doors
and exiting the vehicle.
— The exit warning system does not respond
to people and cannot warn you about every
type of approaching objects, such as cyclists.
Always monitor the traffic as well as the ve-
hicle's surroundings with direct eye contact.
— The display may not appear in time when
vehicles are approaching very quickly.
— The exit warning system does not react to
stationary objects or pedestrians.
— The exit warning system will not provide
alerts if your vehicle is pulled too far into
the parking space so that it is hidden by ad-
jacent vehicles.

Introduction
Depending on the vehicle equipment, various
parking aids will help you when parking and ma-
neuvering.
Parking aid
The parking aid plus assists you while parking
using audio and visual signals to warn you about
objects detected in front of, behind, and next to*
the vehicle > page 147.
The rearview camera shows the area behind the
vehicle in the center display. The lines in the rear-
view camera image help you to park and maneu-
ver > page 149.
The peripheral cameras are an addition to the
rearview camera and help you to see various
areas around the vehicle while parking and ma-
neuvering > page 149.
The rear cross-traffic assist can warn you of ap-
proaching cross traffic when driving in reverse or
exiting a parking space > page 152.
Assisted parking
Park assist helps you to find suitable parking
spaces and to park in and exit these spaces while
the driver monitors the area around the vehicle
and
controls the parking process. Park assist con-
trols the steering movements when parking in
free parking spaces. The driver is still responsible
for accelerating, braking, and shifting gears
=> page 154.
Settings options
You can adjust parking aid functions individually.
The adjustment options depend on the vehicle
equipment.

Fig. 129 Center display: distance display
If the sensors detect an obstacle, audible and vis-
ual signals will warn you.
Visual warnings
The visual warnings in the center display help you
to detect the critical vehicle area and to estimate
the distance to an obstacle.
Red segments (2) show detected obstacles that
are in your vehicle's path. The red lines 2) mark
the expected direction of travel based on the
steering angle. A white segment (8) indicates a
detected obstacle that is outside of the vehicle's
148
path. The closer your vehicle comes to the obsta-
cle, the closer the segments will move to the ve-
hicle. The collision area has been reached when
the next to last segment is displayed. Obstacles
in the collision area, including those outside of
the vehicle's path, are shown in red. Do not con-
tinue driving farther.
Audio signals
The closer your vehicle gets to a detected obsta-
cle, the shorter the time between the audible sig-
nals. A continuous tone sounds when an obstacle
is less than approximately 1 foot (0.30 m) away
from the front or rear of the vehicle. A continu-
ous tone sounds when an obstacle is less than
approximately 0.7 feet (0.20 m) away from the
sides* of the vehicle. Do not continue driving for-
ward or in reverse >@).

stant, the volume of the distance warning
gradually lowers after a few seconds until it
is muted (this does not apply to the continu-
ous tone). If the obstacle comes closer than
it was before the sound was muted, the
tone will sound again. If the obstacle be-
comes farther away than it was before the
sound was muted, no tone will sound. Pay
