Start/Stop system
Description
Applies to: vehicles with Start/Stop syste m
The Start/Stop system can help increase fuel
economy and reduce CO2 emissions.
In Start/Stop mode, the eng ine s hut s 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 w hen needed.
The last Start/Stop system setting is restored
when the ignition is switched on.
Basic requirements for Start/Stop mode
- Th e 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 t ime it stop ­
ped .
- A trailer must not be hitched to the vehicle .
A WARNING
-Never turn off the eng ine 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

Drivin g
During emergency braking, your vehicle will
brake sim ilar to heavy brak ing. ESC and the
associated components (ABS, ASR, EDL)
cannot overcome the laws of physics . In cor­
ners and when road or weather cond it ions
are bad, a full b rake applicat ion ca n cause
the vehicle to skid o r the rear end to swerve,
wh ic h increases the r is k of an accident.
- If the powe r supply fa ils, you cannot set the
par king b rake if it is re leased. In th is case,
par k the vehicle on level ground and secure
it by placing the selector lever in the P posi­
tion . See an authorized Audi dea ler or a u­
thorized Audi Service Facility for assistance .
- Always take the vehicle key with you when
leaving your vehicle, even fo r a short period
of time . This applies particular ly w hen ch il­
dren rema in in the vehicle. Otherwise ch il­
dren could start the engine, release the
park ing brake or operate electrical eq uip­
ment such as powe r windows, which in­
c reases the risk of an acc ident.
- No one sho uld rema in in the vehicle when it
is locked - especially ch ild ren. Locked doo rs
make it mo re diff icu lt fo r eme rgency wor k­
ers to get into the vehicle, which puts lives
at r is k .
0) Tips
When stopping at a traffic s ignal or stopping
in c ity traffic, you can set the parking b rake
manually. The vehicle does no t have to be
he ld w it h t he br ake peda l. The parking b rake
elim ina tes the tendency to creep when a se ­
lecto r lever position is engaged . As soon as
you p ress t he accelerator pedal, the parking
brake releases automat ica lly and your vehicle
starts to move
c::, page 82.
(D Tips
- Occasiona l noises when the parking brake is
set and re leased a re normal and a re not a
cause for concer n.
- The park ing bra ke goes thro ugh a se lf-test
cycle at regular intervals when the ve hicle is
stopped. Any noises associated w ith this a re
normal.
82
- If there is a powe r fail ure, the par king b rake
wi ll not set if it is released, and it wi ll not
re lease if it is
set ~.&. . See an a uth orized
Audi dealer or author ized Audi Se rvice Fa­
cility for assistance.
