The fuel consumption figures in accordance with directive 93/116/CE have been defined during the course of homologation tests which include:

-	an urban cycle which includes a cold start followed by a simulated urban cycle.
-	an extra-urban cycle which includes frequent acceleration in all gears simulating normal out of town usage of the vehi-
	cle. The speed varies between 0 and 120 km/h.
-	the average combined consumption includes 37% of the urban cycle and 63% of the extra-urban cycle.

The type of route, traffic conditions, driving style, weather conditions, trim level/equipment/accessories, presence of special equipment and the state of the vehicle in general can lead to different fuel consumption figures from those established using the above mentioned procedures.

The C 0 2 exhaust emissions (in g/km) are measured during the average combined cycle.
