Vehicle care209In this case reduce speed, avoid
sharp cornering and strong braking. Stop at next safe opportunity and
check tyre pressure.
Control indicator w 3 92.
After adjusting tyre pressure initialise
system to extinguish the control
indicator and restart system.Caution
Deflation detection system warns
just about low tyre pressure
condition and does not replace
regular tyre maintenance by the
driver.
In case of a system malfunction a
message is displayed in the Driver
Information Centre. Set correct tyre
pressure and reinitialise system. If the
failure continues to be displayed,
contact a workshop. The system is
inoperable when ABS or ESC has a
malfunction or a temporary spare
wheel is used. Once the road tyre has
been refitted, check the tyre pressure with cold tyres and initialise the
system.
System initialisation
After tyre pressure correction or
wheel change, the system must be
initialised to learn new circumference reference values:
1. Always ensure that all four tyres have correct tyre pressure3 241.
2. Apply manual parking brake.
3. Press w to reset deflation
detection system.
4. Reset is confirmed by pop-up indication.
After initialisation system
automatically calibrates to new tyre
pressures during driving. After longer
drive the system will adopt and
monitor new pressures.
Always check tyre pressure with cold
tyres.
System has to be reinitialised when: ● Tyre pressure has been changed
● Load condition has been changed
● Wheels have been swapped or exchanged
The system will not warn instantaneously on a tyre blow out or
a rapid deflation. This is due to
required calculation time.
Tread depthCheck tread depth at regular
intervals.
Tyres should be replaced for safety
reasons at a tread depth of 2-3 mm
(4 mm for winter tyres).
250Customer information● Faults and defects in importantsystem components (e.g. lights,
brakes),
● System reactions in special driving situations (e.g. triggeringof an airbag, actuation of the
stability control systems),
● Information on events damaging the vehicle.
In special cases (e.g. if the vehicle
has detected a malfunction), it may be
necessary to save data that would
otherwise just be volatile.
When you use services, the operating data saved can be read together with
the vehicle identification number and
used if necessary. Staff working for
the service net-work (e.g. garages,
manufacturers) or third parties (e.g.
breakdown services) can read the
data from the vehicle. Services
include repair services, maintenance processes, warranty cases and
quality assurance measures.
Data is generally read via the OBD
(On-Board Diagnostics) port
prescribed by law in the vehicle. The operating data which has been read
out documents the technical conditionof the vehicle or individual
components and assists with fault
diagnosis, compliance with warranty
obligations and quality improvement.
This data, in particular information on component stress, technical events,
operator errors and other faults, is
transmitted to the manufacturer
where appropriate, together with the
vehicle identification number. The
manufacturer is also subject to
product liability. The manufacturer
potentially also needs operating data
from vehicles for product recalls.
Fault memories in the vehicle can be
reset by a service company when
carrying out servicing or repairs.
