80Instruments and controlsCaution
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 (DIC).
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
reached TOP-UP OIL LEVEL is
displayed in combination with control
indicator A after the ignition is
switched on for 30 seconds. Check
and top up engine oil 3 156.
To exit the oil level monitor display,
press either trip computer button.

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 (DIC).
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
1800 miles or 2 months, SERVICE
IN appears in the DIC.
When the distance reaches 0 miles or
the service date is due, control
indicators o and A illuminate in the
instrument cluster and SERVICE
DUE appears in the DIC.
The vehicle needs a service. Seek the assistance of a workshop.
Resetting the service display After a service, the service display
must be reset: if available, select the
distance before service display in the
DIC, then press and hold button on
end of wiper lever for approx.
10 seconds until the distance before
service is displayed continuously.

Several minutes of driving at a speed
above 25 mph may be required to
complete the relearn process. The

If problems occur during the relearn

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 3 180, Tyre chains
3 180.
External high-power radio equipment
could disrupt the TPMS.
Each time the tyres are replaced,
TPMS 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 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.
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.

Service information In order to ensure economical and
safe vehicle operation and to
maintain the value of your vehicle, it
is of vital importance that all
maintenance work is carried out at the proper intervals as specified.
The detailed, up-to-date service
schedule for the vehicle is available at
the workshop.
Service display 3 80.
Engine identification 3 199.
Service intervals - except Bus Maintenance of your vehicle is
required every 25,000 miles or after 2 years, whichever occurs first,
unless otherwise indicated by the
service display.
A shorter service interval can be valid
for severe driving behaviour, e.g. for
taxis and police vehicles.Service intervals - Bus only
Maintenance of your vehicle is
required every 20,000 miles or after 1 year , whichever occurs first, unless
otherwise indicated by the service
display.
Confirmations
Confirmation of service is recorded in the Service and Warranty Booklet.The date and mileage is completed
with the stamp and signature of the
servicing workshop.
Make sure that the Service and
Warranty Booklet is completed
correctly as continuous proof of
service is essential if any warranty or
goodwill claims are to be met, and is
also a benefit when selling the
vehicle.
Service display The service interval is based on
several parameters depending on
usage.

Service and maintenance197Additional 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 3 200.
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 corrosion
protection or seal against minor leaks
can cause function problems. Liability
for consequences resulting from the
use of additional coolant additives will be rejected.
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 3 125.
