Economical and environmentally-friendly

s tyle. W it h an anticipatory and econom ic dr iv ing
s tyle, f uel consum ption can be re du ced by ap­
p roximate ly 1 0-15% . The followi ng tips will help
you conse rve the environment and you r money at
the same time .
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 .

Drivin g
~ Brake the vehicle to a stop . The engine stops
shortly before the vehicle comes to a stop or if
the ve hicle is stationary

Add ition al informa tion
The engine stops in the "P", "N" and "D" selector
lever positions .
If you select the "R" selector lever position during
a Stop phase, the engine will start again.
Shift to "P" quickly to prevent the engine from
starting unintentiona lly when shifting t hrough
IIRII.
You can determ ine for you rself if the engine will
stop or not by reducing or increasing the amount
of force you use to press the brake pedal. For ex­
ample, if you only light ly press on the brake ped­
al in stop-and-go traff ic or when turning, the en­
g ine will not switch off when the vehicle is sta­
tionary . As soon as you press the brake down
harder, the eng ine will switch off .
(D Tips
-Press the brake pedal during a Stop phase
to keep the veh icle from roll ing.
- The ignition will turn off if you press the
I STAR T ENGINE ST OP ! button* during a
stop phase . The needle in the tachometer
moves into the
OFF pos it ion .
General information

- The vehicle battery charge level is too low.
- Power consumption is hig h.
The eng ine ca n tur n off aga in when the cond i­

- The Start/Stop system has stopped the engine .
- The vehicle is stationary.
- You exited the vehicle .
In this case, the activated low beam is rep laced
by the pa rking light . The parking lights wi ll
switch off after approximately 30 minutes or
when you lock the veh icle.
