2018 AUDI A3 SEDAN clutch

selector lever position is engaged. As soon as
you press the accelerator pedal, the parking brake releases automatically and your vehicle
starts to move
¢ page 83.
(D Tips
- Occasional noises when the parking brake is
set and re leased 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.
- 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
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.
~ 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 ¢.&. to pre­
vent the vehicle from rolling back when starting.
::li During this time, you can eas ily beg in to move .-<

Driving
A WARNING ,-
Applies to: ve hicles with h ill ho ld assist
- If you do not begin driving immediately or
the engine stalls after releasing the brake
pedal, your veh icle 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.
- Hill hold assist cannot hold the vehicle in
place on all hills (for example, if the ground
is slippery or icy).
- To reduce the risk of an accident, always
make sure the vehicle is situated safely
while stationary.
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
.,.

-Power is still transferred to the wheels
when the engine is running at idle. To pre­
vent the vehicle from "creeping", you must keep your foot on the brake when the en­
gine is running and the selector lever is in
the "D", "S" or "R" position or "tiptronic"
mode is selected.
- Do not inadvertently press the accelerator
peda l when the vehicle is stopped if a gear is
engaged. Otherwise the risk of an accident
increases because the vehicle will start to
move immediately, even if the parking brake
is set.
- To reduce the risk of an accident, do not
press the acce lerator pedal when changing
the selector lever position while the vehicle is stationary and the engine is running.
- Never engage the "R" or "P" selector leve l
positions while driving. It could cause a
crash.
- Before driving down a steep slope, reduce
your speed and shift into a lower gear with
"ti ptron i c".
- Do not ride the brakes or press the brake
pedal too often or too long when driving
downhill. Constant braking causes the
brakes to overheat and substantially re­
duces braking performance, increases brak­
ing distance or causes complete failure of
the brake system.
- If you must stop on an incline, always hold
the vehicle in p lace with the foot brake or
park ing brake to prevent it from rolling
back.
- Never hold the veh icle on an incline with a
sl ip ping clutch. The clutch opens automati­
cally when it becomes too hot from the
overload. The
ml indicator light turns on
and a message appears
¢ page 89 when
the clutch is over loaded .
{LlJ) Note
- When stopping on an incline, do not try to
ho ld the vehicle in place by pressing the ac­
ce lerator pedal while a driving gear is se ­
l ected. This can cause the automatic trans ­
mission to overheat and can damage it. Set
Driving
the parking brake or press the brake pedal
to prevent the vehicle from rolling.
- Allowing the vehicle to roll when the engine
is stopped while the selector lever is in the
"N" position will damage the automatic
transmission, because it is not lubricated
under those circumstances
¢ page 3 78,
Towing with a tow truck.
- The transmission can overheat and be dam­
aged under certain driving and traffic condi­
tions such as frequent starts, creeping for a
long time, or stop-and-go traffic. When the
ml or. indicator light turns on, stop the
vehicle at the next opportunity and let the
transmission cool¢
page 89.
(D Tips
For safety reasons, the park ing brake only re­
l eases automatically when the driver's door is
closed.
Hill descent control
App lies to : vehicles wi th automatic transmiss ions
The hill descent control system assists the driver
when driving down hills.
Hill descent control is act ivated when the selec­
tor lever is in the "D" or "S" posit ion and you
press the b rake pedal. The transmission auto ­
matically se lects a gear that is suitab le for the
hill. Hill descent contro l tries to ma inta in the
speed achieved at the time of braking, within
physical and technica l limitations. If may still be
necessary to adjust the speed with the brakes.
Because hill descent control cannot shift down
farther than 3rd gear, it may be necessary to
shift into tiptronic mode in very steep areas . In
th is case, shift into 2nd or 1st gear in t iptronic
mode to use the engine's braking force to rel ieve
the brakes.
Hill descent control switches
off once the hill lev­
els out or you press the accelerator pedal.
On vehicles with a cruise control system*
¢ page 120, hill descent control is also activated
when the speed is set .

Bulbs
Replacing light bulbs
For your safety, we recommend that you have
your authorized Audi dealer replace any bulbs for
you.
It is becom ing increasingly more and more diffi­
cu lt to replace vehicle light bulbs since in many
cases, other parts of the car must first be re­
moved before you are ab le to get to the bulb.
This applies especially to the light bulbs in the
