Driving
next traffic light is red . This produces an engine
braking effect, which helps to protect the brakes
and tires and reduces the emissions and fue l con ­
sumpt ion to zero (fuel shut-off during decelera­
t ion).
Shift effici ently
An effective way to save fuel is to upshift earlier.
Staying in a gear too long uses fue l unnecessari ­
ly .
P ress down o n the acce lerator peda l slowly and
avoid "kick -down".
Avoid full acceleration
You shou ld rare ly t rave l at the maximum vehicle
speed. High speeds cause a disp roportiona tely
h igh inc rease in fuel consump tion, emissions and
traffic no ise . Slower driving saves fuel.
Reduce idling time
The Start/Stop system* he lps to reduce the idling
time automatically. In vehicles witho ut the Start/
S top system* , it is efficient to swit ch the eng ine
off when stopped at r,;1ilro,;1d crossi ngs and long
red lights . Stopping the engine for 30 -40 sec ­
onds already saves more fuel than the amount of
extra fuel needed to restart the engine.
It t akes a very long time in idle to war m the en ­
g ine up to opera ting tempera ture . Wea r and
emissions are especially high in the warm -up
p hase . Therefore, yo u should begin driving im ­
mediately after starting the engine. Avoid high
RPMs while do ing th is.
Have maintenance performed regularly
By having ma intenance performed regularly on
your vehicle, you can help to reduce f uel con­
sumpt ion befo re yo u even start to dr ive. The
maintenance condition of your vehicle not only
affects t raffic safety and long-term value but a l­
so impacts
fuel consumpt ion . A poorly main ­
tained engine can lead to f uel consumption that
is 10% higher than normal.
Avoid short trips
The engine and exhaust cleaning system m ust
reach the ir opt imal
operating temperature to ef­
fectively reduce consumption and em iss ions.
74
A cold engine uses a d isproportionately high
amount of fue l. The engine reaches operating
temperat ure and cons umption norma lizes on ly
after approximate ly
four ki lometers.
Check the tire pres sure
To save fue l, make sure the t ires are always in­
flated to the correct press ure
¢ page 32 7. The
fuel consumpt ion can increase by S% if the pres ­
s u re is only 0.5 bar too low. Due to the increased
roll ing resistance, low tire pressures w ill also
l ead to greater tire
wear and will affect dr iving
behavior.
Do not drive on
winter tires year-round, as this
will consume up to 10% more f uel.
Eliminate unnecessary we ight
Since eve ry kil og ram o f extra weight in creases
fuel consumption, a quick inspection of the lug­
gage compartment may be worth it to avoid un­
necessary we ight.
When no t be ing used, a roof rack sho uld be re ­
moved to decrease the wind resistance of the ve­
hicle . You will save approx imately
12% of your
fuel when at speeds from 62-75 mph (100-120 km/h).
Save energy
The eng ine drives the generator, which generates
electricity; the fuel consumption also inc reases
with the demand for e lectricity. Therefore, switch
e lectrical equ ipment off when you no longer
need it. Examples of eq uipment 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 shou ld come on to
i ndica te improper operation, they would go
unheeded . Extended idling also prod uces
h eat, w hic h could result i n overheating o r
o ther damage to the veh icle o r othe r prope r­
ty .

Driving
A WARNING
-Always switch th e ignit ion off and take the
vehicle key with you when leav ing the veh i­
cle, eve n for a short per iod of t ime . This ap­
plies particularly when chi ld ren remain in
the ve hicle. Othe rwi se, children coul d sta rt
the engine, re le ase the p arki ng bra ke o r op­
er ate ele ctrica l equipmen t such as power
windows, which increases the risk of an acci ­
dent.
- When the vehicle is loc ke d , no one -particu ­
larly not children -sho uld rema in in the ve­
hicle . Locked doors make it more difficult
f or eme rgency workers to get into the vehi­
cle, which p uts lives at risk.
Starting from a stop

If you do not react enough or no t at all to a dan­
gerous s ituation that was detected by the sys­
tem, p re sense front provides assis tance by ap ­
ply ing the b rakes .
If a collision is imminent, the system will fi rst
provide an

l)_ This reduces the vehicle speed in the
event of a collision. At low vehicle speeds, pre
sense front can initiate a complete deceleration
shortly before a collision with a vehicle driving
ahead
1>. If pre sense front determines that you
are not braking strongly enough when a collision
is imminent, it can increase the braking force .
The following functions trigger in conjunction
with pre sense basic/rear at corresponding vehi ­
cle speeds :
- Reversible tensioning of the front safety belts.
- Closing the windows and sunroof*.
- Inflating the side bolsters* in the seat backrest
and seat surface.
Audi drive select*: the reversible belt tensioner,
the closing of the windows and sunroof* as well
as the inflating of the side bolste rs* on the seat
backrest and seat surface are not active depend­
ing on the mode selected .
Collision avoidance assist
Collision avoidance assist helps you to steer the
vehicle around an obstacle in a critical situation.
If you avoid an obstacle after the acute warning,
then the collision avoidance supports you by ap­ plying slight steering adjustment to correct your
steering wheel angle as long as you are actively
steering. Collision avoidance assist is available at
speeds between approximately 20 mph (30 km/
h) and 90 mph (150 km/h).
Turn assist
When starting to drive and up to speeds of maxi­
mum 6 mph (10 km/h), the turn assist uses a
braking intervention to prevent your vehicle from
colliding with an oncoming vehicle when turning left or right (available in certain countries) . The
braking intervention causes your vehicle to stay
in its lane.
