on poor and sandy road surfaces,  
increased air pollution, presence of  
airborne sand and high dust content,  
driving at high altitude and large  
variations of temperature. Under  
these severe operating conditions,  
certain service work may be required  
more frequently than the regular  
service interval.  
The international service intervals are  
valid for the countries which are not  
listed in the European service  
intervals.  
Select the appropriate engine oil  
based on its quality and on the  
minimum ambient temperature

Caution  
Only use products that meet the  
recommended specifications.  
In case of any spilled oil, wipe it up  
and dispose it properly.  
9 Warning  
Operating materials are  
hazardous and could be  
poisonous. Handle with care. Pay  
attention to information given on  
the containers.  
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 oils for all petrol  
engines with only ACEA quality is  
prohibited, since it can cause engine  
damage under certain operating  
conditions.  
Select the appropriate engine oil  
based on its quality and on the  
minimum ambient temperature  
3 275.  
Service display 3 106.  
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. It is also  
a benefit when selling the vehicle.  
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.  
Additional engine oil additives  
The use of additional engine oil  
additives could cause damage and  
invalidate the warranty.  
272  
Service and maintenance  
Engine oil viscosity grades  
should be maintained all year round.  
The use of additional coolant  
The SAE viscosity grade gives  
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.  
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 3 275.  
Washer fluid  
Use only washer fluid approved for  
the vehicle to prevent damage of  
wiper blades, paintwork, plastic and  
rubber parts. Consult a workshop.  
All of the recommended viscosity  
grades are suitable for high ambient  
temperatures.  
Brake and clutch fluid  
Over time, brake fluid absorbs  
moisture which will reduce braking  
effectiveness. The brake fluid should  
therefore be replaced at the specified  
interval.  
Coolant and antifreeze  
Use only organic acid type-long life  
coolant (LLC) antifreeze approved for  
the vehicle. Consult a workshop.  
The system is factory filled with  
coolant designed for excellent  
corrosion protection and frost  
protection down to approx. -28 °C. In  
cold regions with very low  
temperatures the factory filled coolant  
provides frost protection down to  
approx. -37 °C. This concentration

Technical data  
Information on identification label:  
1 : manufacturer  
Specifications in the vehicle  
documents always have priority over  
those given in this manual.  
Identification plate  
2 : type approval number  
3 : vehicle identification number  
4 : permissible gross vehicle weight  
rating in kg  
Engine identification  
The technical data tables use the  
engine identifier code. The engine  
data table additionally shows the  
engineering code.  
5 : permissible gross train weight  
in kg  
6 : maximum permissible front axle  
load in kg  
Engine data 3 278.  
7 : maximum permissible rear axle  
load in kg  
To identify the respective engine,  
refer to the EEC Certificate of  
Conformity provided with your vehicle  
or other national registration  
documents.  
The Certificate of Conformity shows  
the engine identifier code, other  
national publications may show the  
engineering code. Check piston  
displacement and engine power to  
identify the respective engine.  
8 : vehicle-specific or country-  
specific data  
The identification plate is located on  
the front left or right door frame.  
The combined total of front and rear  
axle loads must not exceed the  
permissible gross vehicle weight.  
Vehicle's kerb weight depends on the  
specification of the vehicle, e.g.  
optional equipment and accessories.  
Refer to the EEC Certificate of  
Conformity provided with your vehicle  
or other national registration  
documents.
