Fault
Fault messages are displayed with a 9 on the top line of the Info-Display.
The rear view camera may not
operate properly when:
● The surrounding area is dark.● The sun or the beam of headlights is shining directly into
the camera lens.● Ice, snow, mud, or anything else covers the camera lens. Clean
the lens, rinse it with water, and
wipe it with a soft cloth.
● The vehicle had a rear-end accident.
● There are extreme temperature changes.

After having changed defective fuses,
close the fuse box cover and press
until it engages.
If the fuse box cover is not closed
correctly, malfunctions may occur.
Instrument panel fuse box
In left-hand drive vehicles, the fuse
box is behind the storage
compartment in the instrument panel.
Open the compartment and push it to the left to unlock. Fold the
compartment down and remove it.
Vehicle care207Wheels and tyres
Tyre condition, wheel condition
Drive over edges slowly and at right
angles if possible. Driving over sharp
edges can cause tyre and wheel
damage. Do not trap tyres on the kerb when parking.
Regularly check the wheels for
damage. Seek the assistance of a
workshop in the event of damage or
unusual wear.
Winter tyres
Winter tyres improve driving safety at temperatures below 7 °C and should
therefore be fitted on all wheels.
All tyre sizes are permitted as winter
tyres 3 242.
In accordance with country-specific
regulations, affix the speed sticker in
the driver's field of view.Tyre designations

Choose a tyre appropriate for the
maximum speed of your vehicle.
The maximum speed is achievable at kerb weight with driver (75 kg) plus
125 kg payload. Optional equipment
could reduce the maximum speed of
the vehicle.
Performance 3 239.
Directional tyres
Fit directional tyres such that they rollin the direction of travel. The rolling
direction is indicated by a symbol
(e.g. an arrow) on the sidewall.
Tyre pressure monitoringsystem
The tyre pressure monitoring system
checks the pressure of all four tyres
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.
208Vehicle careNote
In countries where the tyre pressure monitoring system is legally
required, the use of wheels without
pressure sensors will invalidate the
vehicle operating permit.
The current tyre pressures can be
shown in the Vehicle Information
Menu in the Driver Information
Centre.
The menu can be selected by the
buttons on the turn signal lever.
Press MENU to select the Vehicle
Information Menu X.
Turn the adjuster wheel to select the
tyre pressure monitoring system.
System status and pressure warnings
are displayed by a message
indicating the corresponding tyre in
the Driver Information Centre.
The system considers the tyre
temperature for the warnings.
Temperature dependency 3 211.A detected low tyre pressure
condition is indicated by illumination
of control indicator w 3 94.
If w illuminates, stop as soon as
possible and inflate the tyres as
recommended 3 242.
If w flashes for 60-90 seconds 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 Driver Information
Centre. During this time w may
illuminate.
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.
