next traffic light is red. This produces an engine
braking effect, which helps to protect the brakes
and tires and reduces the emissions and fuel con­
sumption to zero (fuel shut-off during decelera­
tion).
Shift efficiently
An effective way to save fuel is to upshift earlier.
Staying in a gear too long uses fuel unnecessari­
ly .
Press down on the accelerator pedal slowly and
avoid "kick-down".
Avoid full acceleration
You should rarely travel at the maximum vehicle
speed. High speeds cause a disproportionately
high increase in fuel consumption, emissions and
traffic noise. Slower driving saves fuel.
Reduce idling time
The Start/Stop system* helps to reduce the idling
time automatically. In vehicles without the Start/
Stop system, it is efficient to switch the engine
off when stopped
at railroad crossings and long
red lights. Depending on the version of the en­
gine, stopping the engine for as little as five sec­
onds once it has reached operating temperature
still saves more fuel than leaving the engine run­ ning
-even when taking into account the amount
of extra fuel that is used to restart the engine.
It takes a very long time in idle to warm the en­
gine up to operating temperature. Wear and
emissions are especially high in the warm-up
phase. Therefore, you should begin driving im­
mediately after starting the engine. Avoid high
RPMs while doing this.
Have maintenance performed regularly
By having maintenance performed regularly on
your vehicle, you can help to reduce fuel con­
sumption before you even start to drive. The maintenance condition of your vehicle not only
affects traffic safety and long-term value but al­
so impacts
fuel consumption. A poorly main­
tained engine can lead to fuel consumption that
is 10% higher than normal.
Driving
Avoid short trips
The engine and emissions control system must
reach their optimal
operating temperature to ef­
fectively reduce consumption and emissions.
A cold engine uses a disproportionately high
amount of fuel. The engine reaches operating
temperature and consumption normalizes only
after approximately 2.5 miles (4 km).
Check the tire pressure
To save fuel, make sure the tires are always in­
flated to the correct pressure
r=;, page 33 5. The
fuel consumption can increase by S% if the pres­
sure is only 0.5 bar too low. Due to the increased
rolling resistance, low tire pressures will also
lead to greater tire
wear and will affect driving
behavior.
Do not drive on
winter tires year-round, as this
will consume up to 10% more fuel.
Eliminate unnecessary weight
Since every kilogram of extra weight increases
fuel consumption, a quick inspection of the lug­
gage compartment may be worth it to avoid un­
necessary weight.
When not being used, a roof rack should be re­
moved to decrease the wind resistance of the ve­
hicle. You will save approximately 12% of your
fuel when at speeds from 62-75 mph
(100-120 km/h).
Save energy
The engine drives the generator, which generates
electricity; the fuel consumption also increases
with the demand for electricity. Therefore, switch
electrical equipment off when you no longer
need it. Examples of equipment that uses a lot of
energy are air blowers at a high setting, the rear
window defogger and seat heating*.
(D Note
- Do not leave engine idling unattended after
starting. If warning lights should come on
to indicate improper operation, they would go unheeded. Extended idling also produces
heat, which could result in overheating or
