2014 AUDI A5 CABRIOLET clutch

Transmission multitronic, S tronic,
tiptronic
Introduction
Appl ies to vehicles: with multitronic/5 tronic/tiptronic
The automatic transmission is controlled elec­
tronically. The transmission upshifts or down­
shifts automatically depending on which drive
program is se lected.
When a
moderate driving style is used, the
transmission se lects the most economica l
driving mode.
It wi ll then change up early and
de lay the downshifts to give better fuel econ­
omy.
The transmission switches to a sporty mode after a kick -down or when the driver uses a
sporty driving style characteri zed by quick ac­
celerator pedal movements, heavy accelera­
tion, frequent changes in speed and traveling
at the maximum speed.
If desired, the driver can also se lect the gears
manually (tiptronic mode) q page 85.
Various a utomatic transmissions may be in­
stalled, depending on the mode l:
multitronic transmission
The multitronic transmission is a continuously
variab le transmission. Power is trans ferred us­
ing a mu ltidisk clutch. In contrast to conven­
tional automatic transmissions using shifting
operations, the transmission ratio in the con­
t inuously variab le transm iss ion is changed
continuously. This opt imizes the comfort level
and conserves fuel.
S tronic transmission
The 5 tronic is a dual-clutch transmission.
Power is transferred using two clutches that
work independently from one another. They
replace the torque converter used in conven­
tional automat ic transmissions and allow the
ve hicle to accelerate without a noticeable in­
terruption in traction .

tiptronic transmission
In the tiptronic transm ission , power is trans­
f erred by a torque converter.

The selector lever position engaged appears
next to the se lector lever as well as in the in­
strument cluster display.
P -Park
In this se lector lever position the transmis­
sion is mechanica lly locked. Engage P on ly
when the vehicle is
completely stopped q .&.
in Driving the automatic transmission on
page 88.
To shift in or out of position P, you must first
press and hold the brake pedal and then press
the re lease button in the selector lever handle
while moving the selector lever to or from P.
You can shift out of th is position only with the
ignition on .
R • Reverse
Select R only when the vehicle is at a full stop
and the engine is running at idle speed q &. in

Before you move the se lector lever to R, press
both the release button in the hand le of the
selector lever
and the brake pedal at the same
time .
When the ignition is on, th e backup lights illu­
minate when the selector lever is moved into
R.

tions by hand
¢page 89.
On slopes, activate the parking brake first and
then move the selector lever to the P position.
This prevents too much stress from being placed on the locking mechanism.
Vehicles with multitronic transmission : Your
vehicle is equipped with
hill hold assist allow­
ing you to start while on an incline. The sys­
tem is activated when the brake pedal is pressed down and held
for a few seconds. The
br ake pre ssure will hold for
a moment after
the brake pedal loosens to preven t the vehicle
from rolling backwards while starting up.
A WARNING
- The vehicle can also roll when the engine
is stopped .
- Unintended vehicle movement can cause serious injury .
- Never leave your vehicle with the engine
running while in gear . If you must leave
your vehicle when the engine is running,
activate the parking brake and move the
selector lever to P.
- Power is still transmitted to the wheels
when the engine is running at idle. To
prevent the vehicle from "creeping", you
must keep your foot on the brake when
the engine is running and the selector
lever is in D/S or R or "tiptronic" mode is
selected.
- Do not press the accelerator pedal when
changing the selector lever position
while the vehicle is stationary and the
engine is running.
- Never shift into R or P while driving.
- Before driving down a steep slope, re-
duce your speed and shift into a lower
gear with "tiptronic".
- Do not ride the brakes or press the brake
pedal too often or too long when driving
down a hill . Constant braking causes the
brakes to overheat and substantially re­
duces braking performance, increases
braking distance or causes complete fail­
ure of the brake system. -
To prevent the vehicle from rolling back
when stopping on inclines, always hold it
in place with the brake pedal or parking
brake .
- Never hold the vehicle on an incline with
a slipping clutch. The clutch opens auto­
matically when it becomes too hot from
the overload . An indicator lamp
mJ illu­
minates and a driver message appears
¢ page 91 when the clutch is overload­
ed.
- If the engine must remain running, never
have any driving position engaged when
checking under the hood. Make sure the
selector lever has securely engaged and
is locked in P with the parking brake set
¢ page 206. Otherwise, any increase in
engine speed may set the vehicle in mo­
tion, even with the parking brake ap­
plied .
(D Note
-S tronic- and tiptronic transmission :
When stopping on an incline, do not try
to hold the vehicle in place by pressing the accelerator pedal while a driving gear
is selected . This can cause the transmis­
sion to overheat and can damage it. Acti­
vate the parking brake or press the brake pedal to prevent the vehicle from rolling .
- S tronic- and tiptronic transmission : Al­
lowing the vehicle to roll when the en­
gine is stopped and the selector lever is
in N will damage the transmission be­
cause it is not lubricated under those cir­
cumstances.
(D Tips
For safety reasons, the parking brake is re­
leased automatically only when the driv­
er's safety belt is engaged in the buckle.

Do not fill coolant above the "MAX" mark. Ex­
cess coolant will be forced out through the pressure relief valve in the cap when the en­
gine becomes hot .
_& WARNING
-The cooling system is under pressure and
can get very hot. Reduce the risk of
scalding from hot coolant by following
these steps .
- Turn
off the engine and allow itto cool
down.
- Protect your face, hands and arms from escaping fluid and steam by covering
the cap with a large, thick rag.
- Turn the cap slowly and very carefully in a counter-clockwise direction while
applying light, downward pressure on
the top of the cap .
- To avoid being burned, do not spill an­
tifreeze or coolant on the exhaust sys­
tem or hot engine parts . Under certain
conditions, the ethylene glycol in en­
gine coolant can catch fire.
- Antifreeze is poisonous. Always store an­
tifreeze in its original container and well
out of the reach of children.
- If you drain the coolant, it must be
caught and safely stored in a proper con ­
tainer clearly marked "poison".
(D Note
- Do not add coolant if the expansion tank
is empty. Air could enter the cooling sys­
tem and damage the engine. If this is
the case, do not continue driving . Seek
professional assistance.
- Coolant pollutes the environment and
could cause an engine fire . Excess cool­
ant will be forced out through the pres­
sure relief valve in the cap when the en­
gine becomes hot.
- If, in an emergency, only water can be
added, the correct ratio between water
and antifreeze
¢ page 213 must be re­
stored as soon as possible.
Checking and filling 215
'
@) For the sake of the environment
Drained coolant should not be reused. Al­
ways dispose of used coolant while observ­
ing all environmental regulations.
Radiator fan
The radiator fan switches on automatically by
itself .
The radiator fan is driven by the engine via the
V-belt. The viscous clutch regulates the speed
of the fan according to the temperature of the coolant.
An auxiliary electric radiator fan* switches on
and
off depending on coolant temperature
and other vehicle operating conditions.
After you switch the engine
off, the auxiliary
fan can continue running for up to 10 minutes
- even with the ignition
off. It can even switch
on again later by itself ¢.&. , if
- the temperature of the engine coolant rises
du e to the h eat build-up from th e engin e in
the engine compartment, or
- the engine compartment heats up because
the vehicle is parked in intense sunlight.
_& WARNING ~
-To reduce the risk of personal injury nev-
er touch the radiator fan .
- The auxiliary electric fan is temperature
controlled and can switch on suddenly
even when the engine is not running.
- The auxiliary radiator fan switches on au­
tomatically when the engine coolant reaches a certain temperature and will
continue to run until the coolant temper­
ature drops. •
