Parking aid
General notes
The rear parking aid uses an acoustic signal
to indicate the distance between your vehicle
and an obstacle. If you engage reverse gear
while the engine is running, the parking aid is activated automatically.
The parking aid uses three sensors 0043in the
rear bumper to monitor the area behind your
vehicle. The sensors must be free from dirt,
ice or slush. They can otherwise not function
correctly. Clean the sensors regularly, tak-
ing care not to scratch or damage them.
When reverse gear is engaged the system
measures the distance between your vehicle
and an object. If the proximity to the object
behind the vehicle is less than 4.0 ft (1.20 m)
a beeping sound is issued. As the distance to
the object decreases the frequency increa-
ses. When the object is a maximum of 1.0 ft
(30 cm) a continuous tone is issued.
Important safety notes
The parking aid feature is only intended as an
aid. It is not a replacement for your attention
to your immediate surroundings. You are
always responsible for safe maneuvering,
parking and exiting a parking space. When
maneuvering, parking or pulling out of a
parking space, make sure that there are no
persons, animals or objects in the area in
which you are maneuvering.
!When parking, pay particular attention to
objects above or below the sensors, such as
flower pots or trailer drawbars. The park-
ing aid does not detect such objects if they
are in the immediate vicinity of the vehi-
cle. You could damage the vehicle or the
objects.
The sensors may not detect snow and other
objects that absorb ultrasonic waves.
Ultrasonic sources such as an automatic car
wash, the compressed-air brakes of a truck
or a pneumatic drill could cause the park-
ing aid to malfunction.
The parking aid may not function correctly
on uneven terrain.

^
The yellow distance
warning function warn-
ing lamp comes on
while the vehicle is
moving.The distance warning function is malfunctioning or temporarily
inoperative. Possible causes are:
Rthe smart logo in the radiator trim is dirty.
Rfunction is impaired due to heavy rain or snow.
Rthe radar sensor system is temporarily inoperative, e.g. due to
electromagnetic radiation emitted by nearby TV or radio sta-
tions or other sources of electromagnetic radiation.
Rthe system is outside the operating temperature range.
RThe on-board voltage is too low.
If the causes listed above no longer apply, the distance warning
function is operational again.
If the distance warning lamp continues to light up, the distance
warning function electronics are malfunctioning.
