DRIVING TIPS
Avoid high engine speeds
Driving at low engine speeds lowers fuel con‐
sumption and reduces wear.
If necessary, observe the vehicle's gear shift indi‐
cator.
Use coasting conditions
When approaching a red light, take your foot off
the accelerator and let the vehicle coast to a halt.
For going downhill take your foot off the acceler‐
ator and let the vehicle roll.
The flow of fuel is interrupted while coasting.
Switch off the engine during
longer stops
Switching off the engine
Switch off the engine during longer stops, for in‐
stance at traffic lights, railroad crossings or in
traffic congestion.
Auto Start/Stop function
The Auto Start/Stop function of the vehicle auto‐
matically switches off the engine during a stop.
If the engine is switched off and then restarted
rather than leaving the engine running con‐
stantly, fuel consumption and emissions are re‐
duced. Savings can begin within a few seconds
of switching off the engine.
In addition, fuel consumption is also determined
by other factors, such as driving style, road con‐
ditions, maintenance or environmental factors.
Switch off any functions that are
not currently needed
Functions such as seat heating and the rear win‐
dow defroster require a lot of energy and in‐
crease fuel consumption, especially in city and
stop-and-go traffic.
Switch off these functions if they are not needed.
