If engine coolant temperature is
too high, stop vehicle, switch off
engine. Danger to engine. Check
coolant level.
For physical reasons, the coolant temperature gauge shows the coolant temperature only if the coolant level is adequate.
Engine oil level monitor
The engine oil level monitor is correct
only if the vehicle is parked on a level
surface with a cold engine.
If the engine oil level is correct when
the ignition is switched on OIL LEVEL
CORRECT appears briefly in the
Driver Information Centre.
If the engine oil is above the minimum level, press the trip computer button
on the end of the wiper lever within
30 seconds of switching on the
ignition. The message OIL LEVEL is
displayed in combination with the
squares that correspond to the oil
level.
As the oil level diminishes, the
squares in the display are replaced
with dashes.▢▢▢▢▢▢:maximum level▢▢▢- - -:intermediate level- - - - - -:minimum level
If the minimum engine oil level is

Service display When the ignition is switched on, the
remaining distance before the next
service is due may be shown briefly in the Driver Information Centre. Based
on driving conditions, the interval at
which a service will be indicated can
vary considerably.
When the remaining distance before
the next service is less than
3000 km or two months, SERVICE
IN appears in the Driver Information
Centre.
When the distance reaches 0 km or the service date is due, control
indicators o and A illuminate in the
instrument cluster and SERVICE
DUE appears in the Driver
Information Centre.
The vehicle needs a service. Seek the
assistance of a workshop.
Resetting the service displayAfter a service, the service display
must be reset: if available, select the
distance before service display in the
Driver Information Centre, then press
and hold button on end of wiper lever
for approx. ten seconds until the
distance before service is displayed
continuously.

Vehicle care203After a puncture has been repaired
and the driver has inflated the tyres to
the correct tyre pressure, the tyre
pressure monitoring system needs to
recalculate.
Tyre pressure 3 246, Tyre repair kit
3 204.
During driving, select the tyre
pressure menu in the Driver
Information Centre by pressing button on end of wiper lever. Press and holdbutton for approx. five seconds to
initialise recalculation. A
corresponding message appears in
the Driver Information Centre.
Several minutes of driving at a speed
above 40 km/h may be required to
complete the relearn process. The system can only provide limited
information during this time.
If problems occur during the relearn
process, control indicator w remains
illuminated and a warning message is displayed in the Driver Information
Centre.

Vehicle messages 3 103.General information
The use of tyre chains or
commercially available liquid tyre
repair kits can impair the function of
the system. Factory-approved tyre
repair kits can be used.
Tyre repair kit 3 204, Tyre chains
3 204.
External high-power radio equipment
could disrupt the tyre pressure
monitoring system.
Each time the tyres are replaced, the
tyre pressure monitoring system
sensors must be dismounted and
serviced by a workshop.
Tread depth Check tread depth at regular
intervals.
Tyres should be replaced for safety
reasons at a tread depth of two-
three mm (four 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 two 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.
Tyres age, even if they are not used.
We recommend tyre replacement
every six years.
Changing tyre and wheelsize
If tyres of a different size than those fitted at the factory are used, it may be necessary to reprogramme the

Engine oil
Engine oil is identified by its quality
and its viscosity. Quality is more
important than viscosity when
selecting which engine oil to use. The oil quality ensures e.g. engine
cleanliness, wear protection and oil
aging control, whereas viscosity
grade gives information on the oil's
thickness over a temperature range.
Service and maintenance223Dexos is the newest engine oil quality
that provides optimum protection for
diesel engines. If it is unavailable,
engine oils of other listed qualities
must be used.
Select the appropriate engine oil
based on its quality and on the
minimum ambient temperature
3 226.
Topping up engine oil
Engine oils of different manufacturers
and brands can be mixed as long as
they comply with the required engine
oil quality and viscosity.
Use of engine oil with only
ACEA A1/B1 or only A5/B5 quality is
prohibited, since it can cause long-
term engine damage under certain
operating conditions.
Select the appropriate engine oil
based on its quality and on the
minimum ambient temperature
3 226.
Additional engine oil additives
The use of additional engine oil
additives could cause damage and
invalidate the warranty.Engine oil viscosity grades
The SAE viscosity grade gives
information of the thickness of the oil.
Multigrade oil is indicated by two
figures, e.g. SAE 5W-30. The first
figure, followed by a W, indicates the
low temperature viscosity and the
second figure the high temperature viscosity.
Select the appropriate viscosity grade depending on the minimum ambient
temperature 3 226.
All of the recommended viscosity
grades are suitable for high ambient
temperatures.
Coolant and antifreeze
Use only silicate-free long life coolant (LLC) antifreeze approved for thevehicle. Consult a workshop.
The system is factory filled with
coolant designed for excellent
corrosion protection and frost
protection down to approx. -28 °C.
This concentration should be
maintained all year round. The use of
additional coolant additives that
intend to give additional corrosionprotection or seal against minor leaks
can cause function problems. Liability for consequences resulting from the
use of additional coolant additives will
be rejected.
Washer fluid
Use only washer fluid approved for
the vehicle to prevent damage of wiper blades, paintwork, plastic and
rubber parts. Consult a workshop.
Brake fluid
Over time, brake fluid absorbs
moisture which will reduce braking
effectiveness. The brake fluid should therefore be replaced at the specified interval.
AdBlue Only use AdBlue to reduce the
nitrogen oxides in the exhaust
emission 3 143.
