Defensive driving and “flowing” with traffic
Frequent braking and acceleration increases fuel consumption significantly. Just by driving defensively and keeping a sufficiently large distance away from the vehicle in front of you can make up for the speed fluctuations caused by taking your foot off the accelerator. Active braking and accelerating is then not necessarily required.
Calm and smooth driving
Consistency is more important than speed. The more smoothly you drive, the less fuel the vehicle consumes.
When driving on the highway or freeway, a constant, moderate speed is more efficient and economical than constantly accelerating and braking. Usually you can reach your destination just as quickly by driving at a moderate, but steady speed.
The cruise control system can assist in maintaining a uniform driving style.
Moderate use of extra electrical loads
Comfort inside the vehicle is nice and important, but it is important to use them in an environmentally conscious manner.
Some devices can increase fuel consumption when activated (examples):
x Climate control system (air conditioner): If the climate control system has to produce starkly con-trasting temperatures, it requires a large amount of energy, which is generated by the engine. The temperature in the vehicle should therefore not be extremely different from that of the outside tempera-ture. It may be helpful to ventilate the vehicle before driving and then to drive a short distance with the windows open. After that, switch on the air conditioner with the windows closed. Keep the windows closed when driving at high speeds. Open windows increase fuel consumption.
x Switch off seat heating once it has served its purpose.
x Switch off the windshield and rear window defroster as soon as the windows are free of fog and ice.
Additional factors that increase fuel consumption (examples):
x Malfunctioning engine control.
x Driving in the mountains.
x Towing a trailer.
NOTICE
Never let the vehicle coast or roll down a hill in Neutral (N), especially when the engine is not running. The transmission will not be lubricated and will be damaged.

Driving situa-
tions
Requirements and
conditions Vehicle behavior
– Avoid speeds of over
about 160 km/h
(99 mph).
Efficient sailing is possible with
a speed of about 160 km/h
(99 mph).
– Careful selection of
gear (S).
Sporty driving style with acti-
vated sport program increases
fuel consumption. Efficient
sailing in sport program with
combustion engine automati-
cally switched off is possible
with a speed of about 70 km/h
(43 mph).
Driving in cold
months.
– Do not warm up the
combustion engine by
running it with the vehi-
cle stationary.
The temperature of the com-
bustion engine increases very
slowly, but fuel consumption
increases considerably.
– Careful use of heating
for the rear window,
outside mirror, steering
wheel and front seats.
This prevents energy from
being lost and saves energy
for the electric motor.
– Leave the vehicle in a
garage overnight.
This prevents the high-voltage
battery and the vehicle interior
from cooling down too much.
The optimal temperature of the
high-voltage battery is reached
quicker at the beginning of the
journey and the combustion
engine can be switched off
quicker when the vehicle inte-
rior is sufficiently heated.
