Economical and environmentally-friendly
driving
The amount of fue l cons umption, the env iron­
men tal impact and the wear to the engine,
b rakes and t ires dep ends mostly on your dr iv ing
style. W ith an anticipatory and economic driv ing
s tyle, f ue l consumption can be reduced by ap­
p roximate ly 10-15% . The following tips will help
you conserve the environment and your money at
the same time .
Anticipatory dr iving
A veh icle uses the mos t fu el when a cce le ra ting.
W hen you dr ive wi th ant icipat ion, you do not
need to brake as often and so you ac celerate less .
When possib le, let your ve hicle coast wit h a
gear
engaged ,
for example, when you notice that the
next traffic light is red. This produces an engine
braking effect, which helps to protect the brakes
and tires and reduces the emissions a nd fuel con­
sumpt io n to ze ro (f uel shut-off dur ing decelera­
tion) .
Shift efficiently
An effective way to save fuel is to upshift earlier.
Staying in a gear too long uses fue l unnecessari­
ly .
Press down on the acce le rator peda l slowly and
avoid "k ick -down" .
66
Avoid full acceleration
You should rarely travel at the maxim um vehicle
speed. Hig h speeds cause a disproportionate ly
high increase in fue l cons umption, emissions and
traffic noise. Slowe r driving saves fue l.
Reduce idling time
The Start-S top system * helps to re du ce the idling
time automat ic all y. In ve hicles withou t the Star t­
Stop system *, i t is efficient to sw itch the engine
off when stopped at railroad crossings and long
red lights. Stopping the engine for 30-40 sec­
onds a lready saves more fue l than the amo unt of
extra fue l needed to restart the engine.
It takes a very long time in id le to warm the en­
gine up to operating temperature. Wear and
emissions are especially high in the warm- up
phase . Therefore, you shou ld begin driving im­
med iate ly after starting the engi ne. Avoid high
RPMs wh ile doing this.
Have maintenance performed regul arly
By having maintenance pe rformed reg ula rly on
your vehicle, you can help to reduce fuel con­
sumption before you even start to drive. The
mainte nance condition of your vehicle not on ly
affects traffic safety and long- term value but al­
so im pacts
fuel consumption . A poorly main­
ta ined engine can lead to fuel consump tio n t hat
i s 1 0% hig he r th an no rm al.
Avoid short trips
The eng ine and exhaust clean ing system must
r each their op tima l
operating temperature to ef­
fect ively reduce consump tion a nd emissions.
A cold engine uses a d isproportionately high
amount of fuel. T he eng ine reaches operat ing
temperat ure and cons umption no rma lizes only
af ter approximate ly
2.5 miles (4 km).
Check the tire pressu re
To save fue l, make sure the t ires are always in­
flated to t he correct press ure
r=':>page 221. The
fuel consumpt ion can increase by 5% if the pres­
s ur e is only 0 .5 bar too low . Due to t he i ncreased

eco nomy and reduce CO2 emissions.
In Start/Stop mode, the engine shuts off auto­
matically when the vehicle is stopped, such as at
a traffic ligh t. The ignition rema ins switched o n
dur ing this stop phase. The engine w ill restart
automat ica lly when needed.
Applies to A7 Sportback: the Start/Stop system
activates automatically once the ignit ion is
switched on.
Applies to 57 Sportback: the last Start/Stop sys­
tem setting is restored when the ignit ion is
switched on.
Ba sic requirements for Start /Stop m ode
- The driver's door must be closed .
- The driver's seat belt much be fastened.
- The hood must be closed.
- The vehicle must have dr iven faster than
2.5 mph (4 km/h) since the last time it stop­

If you select the R position dur ing a stop phase,
the engine will start again.
Shift to P quick ly to prevent the engine from
starting unintent ionally when shifting through R.
You can determ ine fo r you rself if the engine will
stop or not by reducing or increasing the amo unt
of force you use to press the brake pedal. For ex­
ample, if you only lightly press on the brake ped­

example in the following situat ions:
- The engine has not reached the minim um re­
quired temperature for Start/Stop mode.
- The interior temperature selected by the A/C
system has not been reached.
- The outside tempe ra tu re is extremely high/low.
- The windsh ield is being defrosted® .
- The parking system* is be switched on .
- The vehicle battery charge level is too low.
- The steering wheel is turned at a sharp angle or
is moving.
- After engaging the reverse gear.
- On sharp inclines.
Engine automatically restarts
The standard S tart/Stop mode w ill be canceled
d uring a stop p hase in the following si tuations.
The eng ine restarts without any action by the
driver.
- The vehicle ro lls, fo r example while on a slope .
- The inte rior tempe rature differs from the tem-

\.J ' During emergency braking, your vehicle will
brake similar to heavy braking. ESC and the
associated components (ABS, ASR, EDL)
cannot overcome the laws of physics . In cor­
ners and when road or weather conditions
are bad, a full brake application can cause
the vehicle to skid or the rear end to swerve,
which increases the risk of an accident.
- If the power supply fails, you cannot set the
parking brake if it is released. In this case,
park the vehicle on level ground and secure
it by placing the selector lever in the P posi­
tion. See an authorized Audi dealer or au­
thorized Audi Service Facility for assistance.
- Always take the vehicle key with you when leaving your vehicle, even for a short period
of time. This applies particularly when chil­
dren remain in the vehicle. Otherwise chil­
dren could start the engine, release the
parking brake or operate electrical equip­
ment such as power windows, which in­
creases the risk of an accident.
- No one should remain in the vehicle when it
is locked -especially children. Locked doors
make it more difficult for emergency work­
ers to get into the vehicle, which puts lives
at risk.
(D) Tips
When stopping at a traffic signal or stopping
in city traffic, you can set the parking brake
manually. The vehicle does not have to be
held with the brake pedal. The parking brake
eliminates the tendency to creep when a se­
lector lever position is engaged. As soon as
you press the accelerator pedal, the parking
brake releases automatically and your vehicle
starts to move
c::> page 75.
(D Tips
- Occasional noises when the parking brake is
set and released are normal and are not a
cause for concern.
- The parking brake goes through a self-test
cycle at regular intervals when the vehicle is
stopped. Any noises associated with this are normal.
Driving
- 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
c::> &. . See an authorized
Audi dealer or authorized Audi Service Fa­
cility for assistance.
Starting from a stop
Various convenience and safety functions may be
available when the vehicle begins driving, de­
pending on vehicle equipment .
Starting on hills with the parking brake set
Requirement: the driver's door must be closed
and the driver's safety belt must be fastened.
.,. To start driving comfortably when on a hill, set
the parking brake and begin driving as usual.
The braking force of the parking brake does not
release automatically until the wheels build up
enough driving force.
Starting on hills with hill hold assist
Hill hold assist makes it easier to start on hills.
Requirement: the driver's door must be closed
and the engine must be running.
.. To activate hill hold assist, press and hold the
brake pedal for several seconds. The vehicle
must be in an uphill direction of travel.
After releasing the brake pedal, the braking pow­ er is maintained for a brief moment
c::> ..&. to pre ­
vent the vehicle from rolling back when starting .
During this time, you can easily begin to move
your vehicle.
_& WARNING
A ppl ies to: ve hicles with hill hold assist
- If you do not begin driving immediately or
the engine stalls after releasing the brake
pedal, your vehicle may begin to roll back­
ward. Press the brake pedal or set the park­
ing brake immediately .
- The intelligent technology of hill hold assist
cannot overcome the limitations imposed by
natural physical laws. The increased comfort
offered by hill hold assist should not cause
you to take safety risks.
