140Driving and operatingParking assist
The parking assist makes parking
easier by measuring the distance between the vehicle and obstacles,
and giving acoustic signals. It is the
driver, however, who bears full
responsibility for the parking
manoeuvre.
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 85.
Activation
When reverse gear is engaged, the
system is activated automatically.
The front parking assist can also be activated at a low speed by pressing
the r button.
An illuminated LED in the parking assist button indicates that the
system is ready to operate.
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.
If the r button is pressed once
within an ignition cycle, the front
parking assist is always reactivated
when the vehicle speed goes below a certain value.
Deactivation
Deactivate the system by pressing
the r button.
The LED in the button will go out and
Park Assist Off will be displayed in the
Driver Information Centre.
The system is deactivated
automatically at a certain speed.
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

Functionality
The traffic sign assistant system
detects designated traffic signs via a
front camera and displays them in the Driver Information Centre.
Traffic signs, which will be detected,
are:
Limit and no passing signs ■ speed limit
■ no passing
■ end of speed limit
■ end of no passing

Traffic signs are displayed on the
page Traffic sign detection on the
Driver Information Centre, chosen via the adjuster wheel on the turn signal
lever 3 88.
When another function on the Driver
Information Centre menu was
selected and then Traffic sign
detection page is chosen again, the
last recognised traffic sign will be displayed.
After the traffic sign page is cleared
by the system, the following symbol is
indicated:The content of the traffic sign page is also cleared during driving by
pressing the SET/CLR button on the
turn signal lever for a longer time.
Pop-up function
Speed limits and no passing signs are
displayed as pop-ups on each page
of the Driver Information Centre.
The pop-up function can be
deactivated on the traffic sign page by
pressing the SET/CLR button on the
turn signal lever.

The system is only operable at
vehicle speeds above 35 mph and if
lane markings are available.
When the system recognises an
unintended lane change, the control

bleeding
If the tank has been run dry, the diesel
fuel system must be bled. Switch on
the ignition three times for
15 seconds at a time. Then crank the
engine for a maximum of
40 seconds. Repeat this process after
no less than 5 seconds. If the engine fails to start, seek the assistance of a
workshop.Wiper blade replacement

matching process. See "TPMS
Sensor Matching Process" later in
this section.
■ One or more TPMS sensors are missing or damaged. The warning
message or code and the
malfunction light should go off
when the TPMS sensors are
installed and the sensor matching
process is performed successfully.
Consult your workshop for service.
■ Replacement tyres or wheels do not match the original equipment
tyres or wheels. Tyres and wheels other than those recommended
could prevent the TPMS from
functioning properly.
■ Operating electronic devices or being near facilities using radio
wave frequencies similar to the
TPMS could cause the TPMS
sensors to malfunction.
If the TPMS is not functioning
properly, it cannot detect or signal
a low tyre condition. Consult your
workshop for service if the TPMS
malfunction light and a warningmessage or code come on and stay
on.
TPMS Sensor Matching
Process
Each TPMS sensor has a unique
identification code. The identification
code must be matched to a new tyre/
wheel position after rotating the tyres
or replacing one or more of the TPMS
sensors. The TPMS sensor matching process should also be performed
after replacing a spare tyre with a
road tyre containing the TPMS
sensor.
The malfunction light 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: driver side front tyre,
passenger side front tyre, passenger
side rear tyre, and driver side rear.
Consult your workshop for service or
to purchase a relearn tool. There are
two minutes to match the first tyre/
wheel position, and five minutes
overall to match all four tyre/wheelpositions. If it takes longer, the
matching process stops and must be
restarted.
The TPMS sensor matching process
is:
1. Apply the parking brake.
2. Turn the ignition on.
3. Use the MENU button on the turn
signal lever to select the Vehicle
Information Menu in the Driver
Information Centre (DIC).
4. Use the thumbwheel 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 driver 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 chirp

6.Unscrew valve cap from defective
tyre.
7. Screw the filler hose to the tyre valve.
8. The switch on the compressor must be set to J.
9. Connect the compressor plug to the power outlet or cigarette
lighter socket.
To avoid discharging the battery,
we recommend running the
engine.10. Set the rocker switch on the compressor to I. The tyre is filled
with sealant.
11. The compressor pressure gauge briefly indicates up to 6 bar whilstthe sealant bottle is emptying
(approx. 30 seconds). Then the
pressure starts to drop.
12. All of the sealant is pumped into the tyre. Then the tyre is inflated.
13. The prescribed tyre pressure should be obtained within
10 minutes. Tyre pressure
3 205 . When the correct pressure
is obtained, switch off the compressor.If the prescribed tyre pressure is
not obtained within 10 minutes,
remove the tyre repair kit. Move
the vehicle one tyre rotation.
Reattach the tyre repair kit and
continue the filling procedure for
10 minutes. If the prescribed tyre pressure is still not obtained, the
tyre is too badly damaged. Seek
the assistance of a workshop.
Drain excess tyre pressure with
the button over the pressure
indicator.
Do not run the compressor longer than 10 minutes.
