Parking assist9 Warning
The driver bears full responsibility
for the parking manoeuvre.
Always check the surrounding
area when driving backwards or
forwards while using parking
assist system.
The parking assist makes parking easier by measuring the distance
between the vehicle and obstacles,
and giving acoustic signals.
The system consists of four ultrasonic parking sensors in the rear bumper. If
the vehicle is equipped with a front
parking assist, the system consists of
four additional ultrasonic parking
sensors in the front bumper.
Control indicator r 3 97.
Operation
When reverse gear is engaged, the
front and rear parking assist is ready
to operate.
An illuminated LED in the parking
assist button r indicates that the
system is ready to operate.
The front parking assist can also be activated at a speed up to 7 mph with
a brief press of the parking assist
button.
If r is pressed once within an
ignition cycle, the front parking assist
is deactivated at a speed above
7 mph. It will be reactivated if vehicle
Driving and operating153
speed has not exceeded 16 mph
beforehand. If vehicle speed has
exceeded 16 mph beforehand, front
parking assist remains deactivated
when speed drops below 7 mph.
When the system is deactivated, the
LED in the button extinguishes and
Park Assist Off pops-up in the Driver
Information Centre.
The system is deactivated
automatically when exceeding
16 mph.
If the vehicle is equipped with rear
parking assist only, the system
automatically switches off when
reverse gear is disengaged. Manual
deactivation is also possible by
pressing r.
Indication An obstacle is indicated by a buzzing
sound. The interval between the
sounds becomes shorter as the
vehicle gets closer to the obstacle. When the distance is less than
30 cm, the buzzing is continuous.Fault
In the event of a fault in the system,
r illuminates or a vehicle message
is displayed in the Driver Information
Centre.
Additionally, r illuminates or a
vehicle message is displayed in the Driver Information Centre if a
malfunction of the system due to
temporary conditions like snow
covered sensors is detected.
Vehicle messages 3 105.
Important hints for using the parking assist systems9 Warning
Under certain circumstances,
various reflective surfaces on
objects or clothing as well as
external noise sources may cause the system to fail to detect
obstacles.
Special attention must be paid to
low obstacles which can damage
the lower part of the bumper. If
such obstacles leave the detection area of the sensors during
approach of the vehicle, a
continuous warning tone will
sound.Caution
Performance of the sensors can
be reduced when sensors are
covered, e.g. by ice or snow.
Performance of the parking assist
systems can be reduced due to
heavy loading.
Special conditions apply if there
are taller vehicles involved (e.g.
off-road vehicles, mini vans,
vans). Object identification in the
upper part of these vehicles
cannot be guaranteed.
Objects with a very small reflection
cross-section, e.g. objects of
narrow size or soft materials, may
not be detected by the system.
154Driving and operatingThe parking assist system will not
avoid a collision with objects which are out of the detection range of
the sensors.
Notice
The parking assist system
automatically detects factory-fitted
towing equipment. It is deactivated
when the connector is plugged in.
The sensor may detect a non-
existent object (echo disturbance)
caused by external acoustic or
mechanical disturbances.
Notice
If engaging a forward gear and
exceeding a certain speed, the rear
parking assist will be deactivated
when the rear carrier system is
extended.
If engaging reverse at first, the
parking assist will detect the rear
carrier system and provide a buzzing
sound. Press r briefly to
deactivate the parking assist.
Rear view camera
The rear view camera assists the
driver when reversing by displaying a
view of the area behind the vehicle.
The view of the camera is displayed
in the Colour-Info-Display.9 Warning
The rear view camera does not
replace driver vision. Note that
objects that are outside the
camera's field of view and the
advanced parking assist sensors,
e.g. below the bumper or
underneath the vehicle, are not
displayed.
Do not reverse the vehicle by only looking at the Info-Display and
check the surrounding behind and
around the vehicle before
reversing.
Activation
Rear view camera is automatically
activated when reverse gear is
engaged.
Functionality
The camera is mounted in the tailgate handle and has a viewing angle of
130°.
Driving and operating155
Due to the high position of the camera
the rear bumper can be seen on the
display as a guide to position.
The area displayed by the camera is
limited. The distance of the image that appears on the display differs from
the actual distance.
Guiding lines
Dynamic guiding lines are horizontal
lines in 1 metre intervals projected on
the picture to define the distance to
shown objects.Trajectory lane of the vehicle is
shown in accordance with the
steering angle.
The function can be deactivated in the
menu Settings in the Info-Display.
Vehicle personalisation 3 112.
Warning symbols
Warning symbols are indicated as
triangles 9 on the picture which show
obstacles detected by the rear
sensors of the advanced parking
assist.
Display settings
Navi 650 /Navi 950 : Brightness can be
set with the up/down buttons of the
multifunction knob.
CD 600 : Brightness can be set by first
pressing and then turning the
multifunction knob.
Deactivation
The camera is deactivated when a
certain forward speed is exceeded or
if reverse gear is not engaged for
approx. 10 seconds.
Vehicle care197
matching process should also be
performed after replacing a spare tyre with a road tyre containing the TPMS
sensor.
The malfunction light w and the
warning message or code should go
off at the next ignition cycle. The
sensors are matched to the tyre/
wheel positions, using a TPMS
relearn tool, in the following order: left
side front tyre, right side front tyre,
right side rear tyre and left side rear
tyre. The turn light at the current
active position is illuminated until
sensor is matched.
Consult your workshop for service or
to purchase a relearn tool. There are
2 minutes to match the first tyre/wheel position, and 5 minutes overall to
match all four tyre/wheel positions. If
it takes longer, the matching process
stops and must be restarted.The TPMS sensor matching process is:
1. Apply the parking brake; on vehicles with automatic
transmission set the selector lever
to P.
2. Turn the ignition on.
3. Press MENU on the turn signal
lever to select the Vehicle
Information Menu in the Driver
Information Centre (DIC).
4. Turn the adjuster wheel to scroll to
the tyre pressure menu.
5. Press the SET/CLR button to
begin the sensor matching
process. A message requesting
acceptance of the process should
display.
6. Press the SET/CLR button again
to confirm the selection. The horn sounds twice to signal the
receiver is in relearn mode.
7. Start with the left side front tyre.
8. Place the relearn tool against the tyre sidewall, near the valve stem.Then press the button to activate
the TPMS sensor. A horn chirpconfirms that the sensor
identification code has been
matched to this tyre and wheel
position.
9. Proceed to the right side front tyre,
and repeat the procedure in Step 8.
10. Proceed to the right side rear tyre,
and repeat the procedure in
Step 8.
11. Proceed to the left side rear tyre, and repeat the procedure in
Step 8. The horn sounds twice to
indicate the sensor identification
code has been matched to the left side rear tyre, and the TPMS
sensor matching process is no
longer active.
12. Turn off the ignition.
13. Set all four tyres to the recommended air pressure level
as indicated on the tyre pressure
label.
14. Ensure the tyre loading status is set according selected pressure
