Saving fuel
Energy-conscious driving
z
High fuel consumption is often a result of
failing to d riv e in an energy-conscious
manner.
z
You should therefore drive with energy in
mind – "more m iles with less fuel".
Fuel consump tion depends to a great
extent on your own personal driving style.
The following hints are intended to help
you consum e fuel at a rate tha t is a s close
as possible to the specified levels – see
page 220.
Check your v ehicle’s fuel consumption
every time you refuel. This facilitates early
detection of any irregularities causing
increased fuel consump tion.
Warming up
z
Driving at full throttle or idling while the
eng ine is still cold inc reases engine w ear
and fuel consumption.
z
Drive off immediately after starting.
Warm up the engine by running it at
moderate engine speeds.
Uniform speed
z
Hectic driving significantly increases fuel
consump tion.
z
Do not accelerate and brak e
unnecessarily.
Drive as often as possible in top gear.
The v ehicle c an often be d riv en in 4th or
5th gear from a speed of
30 mph (50 k m/h) in urban traffic.
In fourth gear fuel consumption in the
30 to 50 mp h (50 to 80 km/h) range is
around 25 % low er than in third gear.
In the 44 to 55 mph (70 to 90 km /h)
range, fuel consum ption in fifth gear is
roughly 15 % lower than in four gea r.
Select the next higher gear as soon as
possible, and only change d ow n when
the engine is no longer running perfectly
smoothly.
Idling
z
The eng ine also consumes fuel when
idling .
z
If you have to wait for more than one
minute, it is worthwhile switching off the
engine. Fiv e m inutes of idling
corresponds to approxima tely 0.62 miles
(1km )of d riv ing.
Overrun
z
The fuel supply is automatically cut off
during ov errun, e.g. when the vehicle is
being d riv en down long grad ients or
when braking – see page 141.
z
To enable the overrun cut-off to take
effect and sa ve fuel, during overrun do
not accelerate a nd if in manual
tra nsmission mode do not declutch.
Correct gear selection
z
High revs increa se engine wear and fuel
consumption.
z
Do not race your engine. Avoid driving at
hig h engine speeds.
Making use of the tachometer helps to
sav e fuel. Drive in a low eng ine speed
rang e for each gea r as much as possible
with uniform engine speeds.
