Operation
Remove optional equipment and unnecessa-
r
y
ac
cessories
The more aerodynamic the vehicle, the lower
the fuel consumption. Optional equipment
and accessories (such as roof racks or bike
carriers) reduce the aerodynamic benefits of
the vehicle.
Therefore, we recommend you remove all op-
tional and unnecessary equipment and racks,
especially if you intend to drive at high
speeds.
Other factors which increase fuel consump-
tion (examples):
●
Fault in engine management.
●
Driving on hills.
●
Trailer towing.
WARNING
Always adapt your speed and the distance to
the vehic
les ahead in line with visibility,
weather conditions, the condition of the road
and the traffic situation.
