Start and driving
During its first few hours of running, the inter-
nal friction in the engine is gr eat
er than l
ater
on when all the moving parts have bedded
down.
How the vehicle is driven for the first 1,500 km
influences the future engine performance.
Subsequently, also drive at a moderate rate,
especially when the engine is still cold: this
will lead to less engine wear and tear and will
prolong its useful life.
You should also avoid driving with the engine
speed too low. Change down to a lower gear
when the engine no longer runs “smoothly”. If
the engine revs too much, cut fuel injection to
protect the engine.

Constructive measures to encourage re-
cycling

Driving
Foresight when driving
Accel er
ation causes the v
ehicle to consume
more fuel. If you think ahead when driving,
you will need to brake less and thus acceler-
ate less. Wherever possible, let the car roll
slowly to a stop, with a gear engaged (for in-
stance when you can see that the next traffic
lights are red). This takes advantage of the
engine braking effect, reducing wear on the
brakes and tyres. Emissions and fuel con-
sumption will drop to zero due to the overrun
fuel cut-off.
Changing gear to save energy
An effective way of saving is to change in ad-
vance to a higher gear. Running the engine at
high rpm in the lower gears uses an unneces-
sary amount of fuel.
Manual transmission: shift up from first to
second gear as soon as possible. In any case,
we recommend that you change to a higher
gear upon reaching 2,000 rpm. Choosing the
right gear enables fuel savings. Select the
highest possible gear appropriate for the
driving situation (the engine should continue
functioning with cyclical regularity).
Automatic transmission: accelerate gradu-
ally and without reaching the “kick-down”
position. Avoid driving at high speed
Avoid trav
elling at top speed, whenever pos-
sible. Fuel consumption, emission of harmful
gases and noise pollution multiply dispropor-
tionately as speed is increased. Driving at
moderate speeds will help to save fuel.
Reduce idling time
In vehicles with the Start-Stop system idling is
automatically reduced. In vehicles without
the Start-Stop system it is worth switching off
the engine, for example, at level crossings
and at traffic lights that remain red for long
periods of time. When an engine has reached
operating temperature, and depending on
the cylinder capacity, keeping it switched off
for a minimum of about 5 seconds already
saves more than the amount of fuel necessa-
ry for restarting.
The engine takes a long time to warm up
when it is idling. Mechanical wear and pollu-
tant emissions are also especially high during
this initial warm-up phase. It is therefore best
to drive off immediately after starting the en-
gine. Avoid running the engine at high speed.
Regular maintenance
Regular servicing helps in saving fuel even
before the engine is started. A well-serviced
engine gives you the benefit of improved fuel
efficiency as well as maximum reliability and
an enhanced resale value. A badly serviced engine can consume up to 10% more fuel
than necessary.
Avoid short journeys
The engine and cat
alytic converter need to
reach their optimal operating temperature
in order to minimise fuel consumption and
emissions.
A cold engine consumes a disproportionate
amount of fuel. The engine reaches its work-
ing temperature after about four kilometres
(2.5 miles), when fuel consumption will return
to a normal level.
Check tyre pressure
Always make sure the tyres are inflated to the
correct pressures

Start and driving
Since the luggage rack increases the aer o-
dynamic dr ag
of the vehicle, you should re-
move it when not needed. At speeds of
100-120 km/h (62-75 mph), this will save 12%
of fuel.
Save electrical energy
The engine drives the alternator, thereby
generating electricity. This implies that any
increase in power consumption also increa-
ses fuel consumption! For this reason, switch
off any unneeded electrical devices. Devices
that use a lot of electricity includes the blow-
er at a high setting, the rear window heating
or the seat heating*.
Power management
This system helps to ensur
e relia-
ble starting The power management controls the distri-
bution of el
ectrical ener
gy and thus helps t

o
ensure that there is always enough power
available to start the engine.
If a vehicle with a conventional electrical sys-
tem is left parked for a long time, the battery
will gradually lose its charge because certain
electrical devices, such as the electronic
gearbox lock continues to draw current even
when the ignition is off. In some cases there may not be enough power available to start
the engine.
Your v

ehicle is equipped with an intelligent
power management system to control the
distribution of electrical energy. This signifi-
cantly improves reliability when starting the
engine, and also prolongs the useful life of the
battery.
The main functions incorporated in the power
management system are battery diagnosis,
residual current management and dynam-
ic power management.
Battery diagnosis
The battery diagnosis function constantly
registers the condition of the battery. Sensors
detect the battery voltage, battery current
and battery temperature. This enables the
system to calculate the current power level
and charge condition of the battery.
Residual current management
The residual current management reduces
power consumption while the vehicle is
parked. It controls the supply of power to the
various electrical devices while the ignition is
switched off. The system takes the battery di-
agnosis data into consideration.
Depending on the power level of the battery,
switch off the individual electrical devices
one after the other to prevent the battery from losing too much charge and to ensure
that the engine can be started r
eliably.
Dynamic power management
While the vehicle is moving, this function dis-
tributes the available power to the various
electrical devices and systems according to
their requirements. The power management
ensures that on-board systems do not con-
sume more electrical power than the alterna-
tor can supply, and thus maintains the maxi-
mum possible battery power level. Note
