Vehicle care209If w illuminates at lower temperatures
and extinguishes after driving, this
could be an indicator for approaching
a low tyre pressure condition. Check
tyre pressure.
Vehicle messages 3 103.
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 spare wheel or temporary spare
wheel is not equipped with pressure
sensors. The tyre pressure
monitoring system is not operational
for these tyres. 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.
Operating electronic devices or being close to facilities using similar wave
frequencies could disrupt the tyre
pressure monitoring system.Each time the tyres are replaced, tyre pressure 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 the tyre information label or tyre pressure chart 3 242, and
select the appropriate setting in the Tyre load menu in the Driver
Information Centre 3 96. This setting
is the reference for the tyre pressure
warnings.
The menu Tyre Load only appears if
the vehicle is at a standstill and the
parking brake is applied. On vehicles
with automatic transmission, the
selector lever must be in P.
Select:
● Light for comfort pressure up to
3 people
● Eco for Eco pressure up to
3 people
● Max for full loading
Tyre pressure sensor matching
process
Each tyre pressure sensor has a
unique identification code. The
identification code must be matched
to a new wheel position after rotating
the wheels or exchanging the
complete wheel set and if one or more
tyre pressure sensors were replaced.
210Vehicle careThe tyre pressure sensor matchingprocess should also be performed
after replacing a spare wheel with a
road wheel containing a tyre pressure sensor.
The malfunction light w and the
warning message or code should extinguish at the next ignition cycle. The sensors are matched to the
wheel positions using a relearn tool,
in the following order: left side front
wheel, right side front wheel, right
side rear wheel and left side rear
wheel. The turn signal light at the
current active position is illuminated
until the sensor is matched.
Consult your workshop for service.
There are two minutes to match the first wheel position, and five minutes
overall to match all four wheel
positions. If it takes longer, the
matching process stops and must be restarted.
The tyre pressure sensor matching
process is as follows:
1. Apply the parking brake.
2. Turn the ignition on.3. On vehicles with automatic transmission: set the selector
lever to P.
On vehicles with manual
transmission: select neutral.
4. Use MENU on the turn signal
lever to select the Vehicle
Information Menu in the Driver
Information Centre.
5. Turn the adjuster wheel to scroll to
the tyre pressure menu.
6. Press SET/CLR to begin the
sensor matching process. A
message requesting acceptance
of the process should be
displayed.
7. Press SET/CLR again to confirm
the selection. The horn sounds
twice to indicate that the receiver
is in relearn mode.
8. Start with the left side front wheel.
9. Place the relearn tool against the tyre sidewall, near the valve stem.Then press the button to activatethe tyre pressure sensor. A horn
chirp confirms that the sensor
identification code has been
matched to this wheel position.10. Proceed to the right side front wheel, and repeat the procedure
in Step 9.
11. Proceed to the right side rear wheel, and repeat the procedure
in Step 9.
12. Proceed to the left side rear wheel, and repeat the procedure
in Step 9. The horn sounds twice
to indicate the sensor
identification code has been
matched to the left side rear tyre,
and the tyre pressure sensor
matching process is no longer
active.
13. Turn off the ignition.
14. Set all four tyres to the recommended tyre pressure as
indicated on the tyre pressure
information label.
15. Ensure the tyre loading status is set according to the selected
pressure 3 96.
Vehicle care225
Screw in the towing eye anticlockwise
as far as it will go until it stops in a
horizontal position.
Attach a tow rope – or better still a tow
rod – to the towing eye.
The towing eye must only be used for
towing and not for recovering the
vehicle.
Switch on ignition to release steering
wheel lock and to permit operation of
brake lights, horn and windscreen
wiper.
Switch the selector lever to neutral.
Release the parking brake.
Caution
Drive slowly. Do not drive jerkily.
Excessive tractive force can
damage the vehicle.
When the engine is not running,
considerably more force is needed to
brake and steer.
To prevent the entry of exhaust gases from the towing vehicle, switch on the
air recirculation and close the
windows, when soft top is closed.
Vehicles with automatic transmission: The vehicle must be towed facing
forwards, not faster than 80 km/h nor further than 100 km. In all other cases
and when the transmission is
defective, the front axle must be
raised off the ground.
Seek the assistance of a workshop.
After towing, unscrew the towing eye
clockwise.
Insert cap at the top and engage
downwards.
Towing another vehicle
Wrap a cloth around the tip of a flat
screwdriver to prevent paint damage. Insert the screwdriver in the slot at the
lower bend of the cap. Release the
cap by carefully moving the
screwdriver downwards.
The towing eye is stowed with the
vehicle tools 3 206.
250Customer informationOperating data in the vehicleControl units process data for
operation of the vehicle.
This data includes, e.g.: ● vehicle status information (e.g. speed, movement delay, lateral
acceleration, wheel rotation rate, "seat belts fastened" display)
● ambient conditions (e.g. temperature, rain sensor,
distance sensor)
As a rule such data is transient, not
stored for longer than an operational
cycle, and only processed on board the vehicle itself. Control units often
include data storage (including the
vehicle key). This is used to allow
information to be documented
temporarily or permanently on vehicle
condition, component stress,
maintenance requirements and
technical events and errors.Depending on technical equipment
level, the data stored is as follows:
● system component operating states (e.g. fill level, tyre
pressure, battery status)
● faults and defects in important system components (e.g. lights,
brakes)
● system reactions in special driving situations (e.g. triggering
of an airbag, actuation of the
stability control systems)
● information on events damaging the vehicle
● for electric vehicles the amount of
charge in the high-voltage
battery, estimated range
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 (e.g. repairs,
maintenance), the operating data
saved can be read together with the
vehicle identification number and
used where necessary. Staff working
for the service network ( e.g. garages,
manufacturers) or third parties (e.g.breakdown services) can read the
data from the vehicle. The same
applies to warranty work 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 is read out,
documents the technical condition of
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 uses operating data
from vehicles for product recalls. This
data can also be used to check
customer warranty and guarantee
claims.
Fault memories in the vehicle can be
reset by a service company when
carrying out servicing or repairs or at
your request.
