Anticipatory driving
A vehicle uses the mos t fu el when a ccele ra tin g.
W hen yo u dr ive wi th a ntici pat ion, you do not
need to brake as ofte n an d so yo u acceler ate less .
W hen possi ble, let your vehi cle coast w it h a
gear
engaged ,
for example when you notice that the
next tra ffic light is red . This p roduces an engine
b raking effect, wh ich helps to protect the brakes
a n d tires a nd reduces t he emissions a nd f uel con­
sumpt io n to zero (fuel shut-off dur ing decelera­
tion) .
Shift efficiently
Upshift ing earlier is an effective way to save fue l.
Staying in a gear too long uses fue l unnecessari­
l y .
Press down on the acce le rato r peda l slowly and
avoid "k ic k-dow n".
Avoid full acceleration
You s hould rare ly tr ave l a t t he m axim um ve hicle
speed . High speeds cause a d isp roportionately
h ig h inc rease in fuel consumption, emissions an d
traffic no ise . Slower driving saves fuel.
Reduce idling time
T h e St art /S top system * he lps t o redu ce the i dlin g
time autom atically . In vehicles wi tho ut the Start /
Sto p system, it is eff ic ient to sw itch t he engine
off w hen stopped at ra ilroad cross ings a nd long
red lights . Depending on t he ve rsion of the en­
g ine, stopping the eng ine for as litt le as five sec­
onds once it has reached ope rat ing tempe rature
Driving
st ill saves mo re fue l th an leav ing t he en gine run ­
ning -even when taking into acco unt the amount
of ext ra fuel t hat is use d to restart t he e ngi ne.
It tak es a ve ry long time in idl e to warm the en ­
gine up to o peratin g tem perature . Wear an d
emissions are especially high in the warm -up
phase. The refore, you s hould begin drivi ng im ­
med iate ly after starting the eng ine. Avoid h igh
RPMs wh ile doing this.
Have maintenance performed regularly
By hav ing maintenance pe rformed reg ularly o n
yo ur vehicle, you can help to reduce fue l con ­
s u mption before you even sta rt to drive. The
maintenance cond ition of your vehicle not on ly
affects traffic safety and long-term va lue b ut al­
so impacts
fuel consumption . A poorly ma in­
ta ined engi ne ca n lead to fue l co nsump tion that
i s 1 0% hig her th an no rmal.
Avoid short trips
The eng ine and emissions contro l system must
r each their optima l
operating temperature to ef­
fec tively reduce consump tion and emissions .
A cold engine uses a disp roportionately high
amount of fue l. The e ngine reac hes operat ing
temperat ure and cons umption no rma lizes on ly
after app roxima tely 2 .5 m iles (4 km).
Check the tire pressure
To save f ue l, ma ke sure the ti res are always i n­
f lated to t he correct press ure
c> page 339. The
fuel consumpt io n can increase by 5% if the pres­
s ur e is on ly 0 .5 bar too low . Due to t he increased
r oll ing resis tance, low tire pressures w ill also
l ead to greate r tire
wear an d will affect dr iving
behav ior.
Do not d rive on
winter tires year- ro und , as this
will consume u p to 10% more f uel.
Eliminate unnecessary weight
S ince eve ry pou nd of ext ra weight inc reases fuel
consumption, a quick inspect io n of the luggage
compartment may be wo rth it to avoid un neces-
sary we ight .
