To switch off, select x in the menu bar
again and confirm.
Programming P
Up to 3 preset departure times can be
programmed, either during one day or over one week.
■ Select P in the menu bar and
confirm
■ Select desired preset memory number 1, 2 or 3 and confirm
■ Select day and confirm
■ Select hour and confirm
■ Select minutes and confirm
■ Select Y or x and confirm
■ If necessary, adjust the runtime duration prior to departure and
confirm
The next preset memory number to
be activated is underlined and the
weekday is displayed. Repeat the
procedure to programme the other
preset memory numbers.
Pressing button X during the
procedure will exit without storing
programme adjustments.To delete a preset departure time,
follow the steps for programming until
heating symbol Y flashes. Press
button q or r until oFF appears in
the display and confirm.
Heating stops automatically
5 minutes after the programmed
departure time.
Notice
The remote control system features
a temperature sensor which
calculates the runtime according to
the ambient temperature and the desired heating level (ECO or
HIGH). The system starts
automatically between 5 and
60 minutes prior to the programmed
departure time.
Set weekday, time and heating

If the vehicle battery is disconnected
or its voltage is too low, the unit will
need to be reset.

The preferred heating level for
programmed departure times can be
set to either ECO or HIGH.
Select Y and confirm. ECO or HIGH
flashes in the display. Adjust using the q or r button and confirm.

124Driving and operating
Deviations from the maximum speed
limit may occur briefly when driving
downhill, for physical reasons.
Vehicles also equipped with cruise
control speed limiter: the maximum
speed cannot be exceeded by
depressing the accelerator pedal firmly beyond the point of resistance.
Cruise control speed limiter 3 120.
Parking assist
The parking assist makes reverse
parking easier by measuring the
distance between the rear of the
vehicle and obstacles. It is the driver,
however, who bears full responsibility for parking.
The system consists of four ultrasonic
parking sensors in the rear bumper.
Notice
Attached parts in the detection area
cause system malfunction.
Activation
When reverse gear is engaged, the
system switches itself on
automatically. Readiness for
operation is indicated by a brief
acoustic signal.
An obstacle is indicated by buzzers
and, depending on vehicle, is also
indicated in the Info-Display. The
interval between the buzzers
becomes shorter as the vehicle gets
closer to the obstacle. When the
distance is less than 30 cm, the
buzzer is continuous.
Notice
In versions with Info-Display
indication, the volume of the buzzer
can be adjusted via the Infotainmentsystem. Refer to Infotainment
system manual for further
information.9 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.

150Vehicle care
Incorrect tyre pressures will impair
safety, vehicle handling, comfort and
fuel economy and will increase tyre
wear.
The tyre pressure tables show all
possible tyre combinations 3 178.
For the tyres approved for your
vehicle, refer to the EEC Certificate of Conformity provided with your vehicle
or other national registration
documents.
The driver is responsible for correct
adjustment of tyre pressure.9 Warning
If the pressure is too low, this can
result in considerable tyre warm-
up and internal damage, leading to tread separation and even to tyre
blow-out at high speeds.
Tyre pressure monitoring
system
The tyre pressure monitoring system
checks the pressure of all four wheels once a minute when vehicle speed
exceeds a certain limit.Caution
Tyre pressure monitoring system
warns only about low tyre pressure
condition and does not replace
regular tyre maintenance by the
driver.
All wheels must be equipped with pressure sensors and the tyres must
have the prescribed pressure.
Notice
In countries where the tyre pressure
monitoring system is legally
required, the use of wheels without
pressure sensors will invalidate the
vehicle type approval.
Tyre pressures in display
The current tyre pressures can be
shown in the Driver Information
Centre 3 86.
With the vehicle stationary, press
button on end of wiper lever
repeatedly until the tyre pressure
menu is displayed.

Vehicle care151
Low tyre pressure condition
A detected low tyre pressure
condition is indicated by illumination
of control indicator w 3 84 and a
corresponding message appears in
the Driver Information Centre.
If w illuminates, stop as soon as
possible and inflate the tyres as
recommended 3 178.
After inflating, driving may be
required to update the tyre pressure
values in the Driver Information
Centre. During this time w may
illuminate.
If w illuminates at lower temperatures
and extinguishes after some driving,
this could be an indicator for getting low pressure. Check tyre pressure.
If the tyre pressure must be reduced
or increased, switch off ignition.
Only mount wheels with pressure
sensors, otherwise the tyre pressure
will not be displayed and w flashes for
several seconds then illuminates continuously together with a
corresponding message in the Driver
Information Centre.
A spare wheel or temporary spare
wheel is not equipped with pressure
sensors. The tyre pressure
monitoring system is not operational
for these wheels. For the further three wheels, the system remains
operational.
Control indicator w and the
corresponding message appears at
each ignition cycle until the tyres are
inflated to the correct tyre pressure.
Driver Information Centre 3 86.
Vehicle messages 3 87.Puncture
A puncture or severely under-inflated
tyre is indicated by illumination of
control indicator w together with F
3 82 and a corresponding message
appears in the Driver Information
Centre.
Tyre pressure 3 178, Tyre repair kit
3 154, Spare wheel 3 158, Wheel
changing 3 157.
Temperature dependency
Tyre pressure depends on the
temperature of the tyre. During
driving, tyre temperature and
pressure increase.
The tyre pressure value displayed in
the Driver Information Centre shows
the actual tyre pressure. Therefore it
is important to check tyre pressure
with cold tyres.
