Keys, doors and windows21Radio remote control
Used to operate:■ Central locking system
■ Anti-theft locking system
■ Anti-theft alarm system
■ Power windows
■ Sunroof
The radio remote control has a range of approx. 20 metres. It can be
restricted by external influences. The
hazard warning flashers confirm
operation.
Handle with care, protect from
moisture and high temperatures and
avoid unnecessary operation.
Fault
If the central locking system cannot
be operated with the radio remote
control, it may be due to the following:
■ Range exceeded
■ Battery voltage too low
■ Frequent, repeated operation of the
radio remote control while not in
range, which will require re-
synchronisation
■ Overload of the central locking system by operating at frequent
intervals, the power supply is
interrupted for a short time
■ Interference from higher-power radio waves from other sources
Unlocking 3 22.
Basic settings
Some settings can be changed in the Settings menu in the Info-Display.

Deactivation
Unlocking the vehicle deactivates the
anti-theft alarm system.
AlarmWhen triggered, the alarm sounds via
a separate battery-backed power
sounder, and the hazard warning
lights flash simultaneously. The
number and duration of alarm signals are stipulated by legislation.
The alarm can be silenced by

260Vehicle care
If w flashes for 60-90 seconds and
then illuminates continuously, there is a fault in the system. Consult a
workshop.
After inflating, driving may be
required to update the tyre pressure
values in the DIC. 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.
Vehicle messages 3 125.
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
illuminates continuously.
A temporary spare wheel is not
equipped with pressure sensors. The
tyre pressure monitoring system is
not operational for these wheels.
Control indicator w illuminates. For
the further three wheels the system
remains operational.The use of commercially available
liquid tyre repair kits can impair the
function of the system. Factory-
approved repair kits can be used.
External high-power radio equipment
could disrupt the tyre pressure
monitoring system.
Each time the tyres are replaced, tyre pressure monitoring system sensors
must be dismounted and serviced.
For the screwed sensor: replace
valve core and sealing ring. For
clipped sensor: replace complete
valve stem.
Vehicle loading status Adjust tyre pressure to load condition according to tyre information label or
tyre pressure chart 3 308, and select
the relevant setting in the menu Tire
Load in the DIC, Vehicle Information
Menu 3 118.
Select:
■ Light for comfort pressure up to
3 people
■ Eco for Eco pressure up to
3 people
■ Max for full loading
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 exchanging the complete wheel set
and if one or more TPMS sensors
were replaced. The TPMS sensor
