Displays the fuel level in the tank.
Control indicator Y illuminates if the
level in the tank is low. Refuel
immediately 3 144.
Never run the tank dry. Erratic fuel
supply can cause catalytic converter
to overheat 3 128.

Service display
The engine oil life system lets you
know when to change the engine oil
and filter. Based on driving
conditions, the interval at which an
engine oil and filter change will be
indicated can vary considerably.

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

Interrupt your journey immediately.
Remove key and check drive belt
condition and tensioning before
seeking the assistance of a
workshop.
Malfunction indicator light
Z illuminates or flashes yellow.
Illuminates when the ignition is
switched on and extinguishes shortly
after the engine starts. If it does not
illuminate, seek the assistance of a
workshop.
Can illuminate briefly when driving;
this is normal and does not indicate a system fault.
Illuminates when the engine is
running
Fault in the emission control system. The permitted emission limits may be exceeded. Fuel economy and vehicle
driveability may be impaired. Seek
the assistance of a workshop
immediately.Control indicator Z also illuminates if
there is a fault in the diesel particle
filter 3 127 or with the automatic
transmission 3 131. Seek the
assistance of a workshop as soon as
possible.
Ensure the fuel filler cap is screwed in completely 3 144.
Flashes when the engine is
running
Fault that could lead to catalytic
converter damage 3 128 . Ease up on
the accelerator until the flashing
stops. Seek the assistance of a
workshop immediately.
Service vehicle soon
g illuminates yellow.
Illuminates when the engine is
running to indicate a fault in the
engine or transmission electronics. The electronics switch to an
emergency running programme, fuel
consumption may be increased and
vehicle handling may be impaired.In some cases, the fault can be
eliminated by switching the engine off and back on again. If g illuminates
again after restarting the engine, the
vehicle may need a service.
Have the cause of the fault eliminated
by a workshop.
Brake system R illuminates red.
Illuminates when the ignition is switched on and extinguishes shortly
after the engine starts. If it does not
illuminate, stop and seek the
assistance of a workshop.
If it stays lit while the engine is
running, the brakes do not operate as
normal, or leaks are found in the
brake system, do not attempt to drive
the vehicle. Have the vehicle towed to a workshop for inspection and repair.9 Warning
Stop. Do not continue your
journey. Consult a workshop.

178Vehicle care
If the tyre pressure is to be reduced orincreased, switch off the ignition. Tyre
pressures 3 176, 3 207.
External high-power radio equipment
could disrupt the tyre pressure
monitoring system.
The tyre pressure monitoring system
valve cores and sealing rings must be
replaced each time the tyres are
changed.
Temperature compensation
Tyre pressure depends on the
temperature of the tyre. During
driving, tyre temperature and
pressure increase.
The tyre pressure value shown in the
display is the actual tyre pressure.
Therefore it is important to check tyre pressure with cold tyres.
Tread depth
Check 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).For safety reasons it is recommended that the tread depth of the tyres on
one axle should not vary by more than
2 mm.
The legally permissible minimum
tread depth (1.6 mm) has been
reached when the tread has worn
down as far as one of the tread wear
indicators (TWI). Their position is
indicated by markings on the
sidewall.
If there is more wear at the front than
the rear, swap round front wheels and
rear wheels. Ensure that the direction
of rotation of the wheels is the same
as before.
Tyres age, even if they are not used.
We recommend tyre replacement
every 6 years.
Changing tyre and wheel
size
If tyres of a different size than those
fitted at the factory are used, it may be necessary to reprogramme the
speedometer as well as the nominal tyre pressure and make other vehicle modifications.
After converting to a different tyre
size, have the label with tyre
pressures replaced.9 Warning
Use of unsuitable tyres or wheels
may lead to accidents and will
invalidate the vehicle type
approval.
If wheel rims of a different type are to
be installed, the wheel nuts may also
need to be changed. We recommend you consult your service partner.
