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 .

-Always hold the steering whee l with your
hands in the 9 o'clock and 3 o'clock posi­
tions to reduce the risk of injury if the airbag
deploys.
- Never hold the steer ing wheel in the 12
o'clock position or with both hands on the
rim or the center of the steer ing wheel.
Holding the steering wheel incorrectly s ig­
nificantly increases the risk of in jury to the
hands, arms and head if t he a irbag dep loys.

,.. Turn the steering wheel until you hear the
steering wheel lock.
The locked steering helps prevent vehicle theft.
A WARNING
- Never turn off the engine before the vehicle
has come to a complete stop. The full func­
tion of the brake booster and the power
steering is not guaranteed. You must use more force to turn or brake . Because you
cannot steer and brake as you usually
would, this co uld lead to accidents and seri-
. . . ous mJunes .
-Never remove the ignit ion key from the ign i­
t ion loc k while the vehicle is moving. Other­
wise, the steering lock could suddenly en­
gage and you would not be able to steer the
vehicle.
- If you leave the veh icle, switch the ignit ion
off and take the vehicle key with you. Other­
wise, the engine could be started or electri­
cal equipment such as the power windows
could be operated. This can lead to serious
injury.
- For safety reasons, always park the vehicle
with the selector lever in the P position.
Otherwise, there is the risk that the vehicle
could roll unintentionally .
(D Note
If the engine has been under heavy load for
an extended period of t ime, heat builds up in
the engine compartment after the engine is
switched off and there is a risk of damaging
the engine . For this reason, let the engine run
for at idle
for approximately two minutes be­
fore shutting it
off.
@ Tips
For up to 10 minutes after stopping the en­
gine, the radiator fan may turn on again auto­
matically or it may continue to run (even if
the ignition is sw itched
off) for the following
reasons:

- The coolant temperature is increasing due
to trapped heat.
- If the engine is warm and the engine com­
partment also heats up from strong sun­

Start/Stop system
Description
Applies to: vehicles wit h Start/Stop system
The Start/Stop system can help increase fuel
economy and reduce CO2 emissions.
In Start/Stop mode, the engine shuts off auto ­
matically when the vehicle is stopped, such as at
a traffic light. The ignition remains switched on
during this stop phase. The engine w ill restart
automat ically when needed.
The Start/Stop system is automatically activated
as soon as the ignition is switched on.
Basic requirements for Start/Stop mode
-The driver's door must be closed .
- The driver's seat belt much be fastened.
- The hood must be closed.
- The vehicle must have driven faster than
2 mph
(3 km/h) since the last time it stopped.
(D Note
Always switch the Start/Stop system off when
driving through water
c> page 81.
(D Tips
The engine stops shortly before the vehicle
comes to a stop
ll. The full function of the
brake booster and the power steering is still
available.

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

set and re leased are normal and are not a
cause for concern.

cycle at regular intervals when the vehicle is
stopped. Any noises associated with this are normal.
- If there is a power failure, the parking brake will not set if it is released, and it will not
release if it is
set¢&. See an authorized

Automatic transmission
Introduction
Applies to: vehicles with automatic transmiss ions
T he automatic transmission is controlled elec­
tronically . Upshifting and downshifting occur au­
tomatically.
When a
moderate driving style is used, the
transm ission selects the most economica l dr iv ing
mode. The transmission upshifts at a lower RPM
and downshifts at a higher RPM to improve fuel
efficiency.
In the "S" selector lever position, the transm is­
sion switches to a sporty mode after a kick-down
or when the driver uses a
sporty driving style
characterized by quick accelerator pedal move­
ments, heavy acce leration, frequent changes in
speed and traveling at the maximum speed.
If desired, the driver can also select the gears
manually (tiptronic mode) ¢ page 88, Manual
shifting (tiptronic mode).
The S tronic is a dual-clutch transmission. Power
is transferred using two clutches that work inde­
pendently from one another. They replace the
torque converter used in conventional automatic
.,.
