Control indicators
The control indicators described are
not present in all vehicles. The
description applies to all instrument
versions. When the ignition is
switched on, most control indicators
will illuminate briefly as a functionality
test.
The control indicator colours mean:
red=danger, important

Driving and operating131
When ESP®Plus
is deactivated the
control indicator v illuminates.
ESPoff also appears in the service
display.9 Warning
Do not deactivate ESP® Plus
if a
run-flat tyre has lost pressure.
ESP® Plus
is reactivated by pressing
the v button. ESPon appears in the
service display. ESP® Plus
is also
reactivated the next time the ignition is switched on.
Driver assistance
systems9 Warning
Driver assistance systems are
developed to support the driver
and not to replace the driver's
attention.
The driver accepts full
responsibility when driving the
vehicle.
When using driver assistance
systems, always take care
regarding the current traffic
situation.
Cruise control
The cruise control can store and
maintain speeds of approx. 20 to
120 mph.
Deviations from the stored speeds may occur when driving uphill or
downhill.
For safety reasons the cruise control cannot be activated until the foot
brake has been operated once.
Do not use the cruise control if it is not advisable to maintain a constant
speed.
With automatic transmission or
manual transmission automated, only
activate cruise control in automatic
mode.
Control indicator m 3 85.
174Vehicle careTyre pressure monitoring
system The vehicle may be fitted with a tyrepressure monitoring system or a tyre
deflation detection system 3 175.Caution
Modifications made to the tyre
pressure monitoring system
(TPMS) by anyone other than an
authorised service facility may
void authorisation to use the
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.
Winter tyres or additional wheel sets
have to be fitted with sensors,
otherwise the system will not work
and the control indicator A illuminates
continuously.
If A lights up, stop as soon as
possible and inflate the tyres as
recommended 3 217.
After inflating, driving may be
required to extinguish A.
If A lights up at lower temperatures
and extinguishes after some driving,
this could be an early indicator for getting low pressure. Check tyre
pressure.
The tyre pressure monitoring system
malfunction indicator is combined
with the low tyre pressure controlindicator. If the system detects a
malfunction, the control indicator will
flash for approx. 1 minute and then
remain continuously illuminated. This sequence will continue upon
subsequent vehicle start‐ups as long as the malfunction exists.
A temporary spare wheel is not
equipped with a pressure sensor. The
tyre pressure monitoring system is
not operational for these wheels.
Control indicator A illuminates.
Operating electronic devices or being
near facilities using radio wave
frequencies similar to the tyre
pressure monitoring system could
cause the tyre pressure monitoring
system sensors to malfunction.
Tyre pressure monitoring system malfunctions may occur for a variety
of reasons, including the installation
of replacement or alternate tyres or
wheels on the vehicle that prevent the tyre pressure monitoring system fromfunctioning properly. Always check
the tyre pressure monitoring system
malfunction control indicator after
replacing one or more tyres or wheels
Vehicle care175
on your vehicle to ensure that the
replacement or alternate tyres and wheels allow the tyre pressure
monitoring system to continue to
function properly.
The use of commercially available
liquid tyre repair kits can impair the
function of the system. Factory
approved repair kits can be used.
System initialisation After a wheel change or tyre pressure
adjustment the system must be
initialised: inflate the cold tyres to the
prescribed pressure according to the
tyre information label or this
document 3 217. Then switch on
ignition and press and hold the DDS
button for approx. 4 seconds. The
control indicator A flashes three
times.
If the tyre pressure difference
between the left and the right wheel
on one axle is more than 30 kPa, tyre
pressure monitoring system
malfunction will be indicated, as the
vehicle starts moving for the first time after initialisation. Adjust tyre
pressure and repeat initialisation.Notice
The system needs to be initialised
after tyre pressure change,
otherwise it will not be able to warn
properly.
Each time the tyres are replaced, the
tyre pressure monitoring system
sensors have to be dismounted and
serviced. For the screwed sensor
replace the valve core and sealing
ring, for the clipped sensor replace
complete rubber valve stem.
Auto learn function
After changing wheels the vehicle
must be stationary for approx.
20 minutes, before the system
recalculates. The following relearn
process takes up to 10 minutes of
driving with a minimum speed of
16 mph.
Tyre deflation detection
system The tyre deflation detection system
continually checks the rotation speed
of all four tyres.
If a tyre loses pressure the control
indicator w illuminates red. Stop
immediately and check tyre pressure.
Control indicator w 3 83.
