Electrical devices
GETTING TO KNOW
Only use electrical devices for the amount of time
YOUR CAR
needed. The heated rear window, additional
headlights, windscreen/rear window wipers and
heater fan need a considerable amount of energy,
therefore increasing fuel consumption (by up to 25%
SAFETY
in the urban cycle).
Climate control system
STARTING AND
The use of the climate control system leads to higher
DRIVING
fuel consumption. If the temperature outside
permits, try to use ventilation only.
WARNING LIGHTS
Devices for aerodynamic control
AND MESSAGES
The use of non-certified devices for aerodynamic
control may adversely affect air drag and fuel
consumption.
IN AN EMERGENCY
DRIVING STYLE
Starting
SERVICING AND
MAINTENANCE
Do not warm up the engine at low or high revs when
the car is stationary; this causes the engine to warm
up more slowly, thereby increasing fuel consumption
and emissions.
TECHNICAL
SPECIFICATIONS
It is advisable to set off immediately and slowly,
avoiding high revs: this allows the engine to warm up
more quickly.
INDEX

Unnecessary actions
Avoid revving up when at traffic lights or before
stopping the engine. This and also double declutching
is absolutely pointless on modern cars and also
increases consumption and pollution.
Gear selection
Use a higher gear as soon as traffic and road
conditions allow. Using a low gear for faster
acceleration will increase consumption.
In the same way improper use of a high gear
increases consumption, emissions and engine wear.
Maximum speed
Fuel consumption increases considerably with speed.
Keep speed as constant as possible, avoiding
unnecessary braking and acceleration, which have a
significant cost in terms of both fuel consumption
and emissions.
Acceleration
Sudden acceleration has a very negative effect on fuel
consumption and emissions: accelerate gradually.
