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.

!Do not drive in the overrevving range, as
this could damage the engine.
HEnvironmental note
Avoid driving at high engine speeds. This
unnecessarily increases the fuel consump-
tion of your vehicle and harms the envi-
ronment as a result of increased emissions.
The overrevving range of the engine is shown with dashed lines in the orange marking of
rev counter 0043. The fuel supply is interrupted
to protect the engine when the overrevving
range is reached.
Dashboard clock 0044is synchronized with the
clock in the on-board computer.
Rev counter 0043, together with dashboard
clock 0044, can be rotated approximately 60° on

els (

fuel consumption.
The display shows the fuel consumption over
the previous 15 minutes as a bar chart. The
display additionally shows the current fuel
consumption as a numeric value in the upper
right section of the display.
If you switch off the ignition, or change the
distance unit, the fuel consumption data is
deleted automatically.
You can change the distance unit in the Dis‐
playsubmenu (Ypage 116).
Coolant temperature menu
Under normal operating conditions and with
the specified coolant level, the coolant tem-
perature may rise to 230‡(110 †).
Example: coolant temperature
XPress the 0063or0064 button on the steer-
ing wheel to select the coolant temperature
display.
The display shows the current coolant tem-
perature as a bar in the range between 50
and 110 †.
If the coolant temperature rises above
110 †, then the display shows a display
message (

message. You could otherwise damage the
engine.

Stop Switch OffEngine
The coolant temperature has exceeded 230 ‡(110 †). The airflow to
the engine radiator may be blocked or the coolant level may be too
low.
GWARNING
The engine is not being cooled sufficiently and may be damaged.
Do not drive when your engine is overheated. This can cause some
fluids which may have leaked into the engine compartment to catch
fire.
Steam from an overheated engine can cause serious burns, which
can occur just by opening the engine compartment cover.
There is a risk of injury.
XPull over and stop the vehicle safely and switch off the engine,
paying attention to road and traffic conditions.
XSecure the vehicle against rolling away (Ypage 100).
XLeave the vehicle and keep a safe distance from the vehicle until
the engine has cooled down.
XCheck the coolant level and top up the coolant. Observe the notes
as you do so (Ypage 210).
XIf you need to add coolant more often than usual, have the engine coolant system checked.
XMake sure that the air supply to the engine radiator is not
blocked, e.g. by snow, slush or ice.
XDo not start the engine again until the coolant temperature is
