S tronic transmission
Applies to vehicles: w ith S tronic®
Introduction
Your vehicle is equipped with a S tronic transmission, also called a
double -clutch system/transmission.
Power is transferred between the engine and the transmission by means of two independent clutches. They replace the torque
converter of conventional automatic transmissions and al low the
vehic le to accelerate without a noticeable break in the power flow .
With the aid of
ti pt ronic, the gears can optionally be shifted manu­
ally => page 118 . •

& WARNING
• Never place the selector lever in the R or P po sition while the
vehicle is moving -risk of an accident !
• W ith the engine running , it is necessary to hold the vehicle with
the foot brake in all selector lever positions (except P and Nl,
because even at idle speed the transfer of power is never
c ompletely interrupted -the vehicle ''creeps ". If the vehicle is
stationary and the transmission is engaged , the engine should
never be speeded up unintentionally (e.g . manually from under the
hood). Otherwi se the vehicle will immediately start to move -
sometimes even if the parking brake is firmly applied - risk of an
accident!
• Before you or other persons open the hood and work on a
running engine , the selector lever must be moved to P and the
parking brake applied firmly - risk of an accident! Follow the
warning stickers~

The selector lever lock is effective only when the vehicle is
stationary and at speeds below 5 km/h. At higher speeds, the lock in
the N position is automatically switched off.
The selector lever is not locked when rapid shifts are made through
t he N position (e.g . from R to Dl. This allows you to "rock" the vehicle
if it becomes stuck . If the lever is in the N position for more than
1 second with the brake pedal not depressed, the selector lock
engages automatically.
Release b utt o n
The release button in the selector lever handle prevents accidental
shifts in to certain selector lever positions. When you press the
re lease button, the selector lever lock is cancelled. In the illustra ­
t ion, the positions in which the release button has to be pressed are
highlighted in color=>

The ignition key can only be remove after the ignition is switched off
if the selector lever is in P . As long as the ignition key is removed, the
selector lever is locked in P.
[ i J Tip s
If the selector lever does not engage, there is a malfunction . The
engine is disabled to prevent the vehicle from driving off uninten­
tiona lly. To a llow the selector lever to engage again, proceed as
follows: Press and release the brake pedal. •

pa ge 107. At low ambient temperatures (14 °F / -10 °C), it is only
po ss ible to star t the eng ine with the se lec tor lever in P .
Whe n par king on leve l ground, it is su ff ic ient to place the selec to r
lever in P. On a steeply s loping road, you should first apply the
p ark ing bra ke fi rmly and th en place the s elec tor lev er in P . T hi s way,
you do not overload the paw l mechanis m and it is easier to move
t h e s elector lever out of P.
& WARNING
• Never leave your vehicle with the engine running while in gear.
If you must leave your vehicle with the engine running, set the
parking brake and engage the park lock .
• When the engine is running and the transmission is in gear (0 ,
S or R l or in "tiptronic " mode , it is essential that you stop the
vehicle w ith the footbrake . When idl ing , the transmission of power
does not stop completely -the vehicle "creeps ".
• Do not accelerate when you change the selector lever position
with the vehicle stationary and the engine running -risk of an acci ­
dent!
• Never place the selector lever in the R or N position while the
vehicle is moving - risk of an accident !
Controls and equip ­
ment
& WARNING (continued )
• If you have to bring your vehicle to a stop while on an incline,
keep the foot brake depressed all the way down so that the vehicle
does not start to roll backward . You should never hold the vehicle
using the clutch pedal if you are going to be stopped on an incline .
If you do , the clutch will start to slip when it overheats caused by
the constant overload. This is dangerous because if the vehicle starts to roll backward , you could cause an accident . If the clutch
should start to slip , you will feel the vehicle "jerk" and the selector
lever display will start blinking .
• Before driving down a steep slope , reduce your speed and shift
into a lower gear w ith "tiptronic ".
• Do not ride the brake s or apply the brake pedal too often or too
long . Constant brak ing causes the brakes to overheat and
substantially reduces braking performance , increases braking
distance or causes complete failure of the brake system . •

Why safety belts?
Frontal co11isions and the law of physics
Front al crashes create very strong forces for pe ople riding
in vehicles.

The physical principles are simple. Both the vehicle and the passen­
gers possess energy which varies with vehicle speed and body
we ight . Engineers cal l this energy "kinetic energy ."
T he higher the speed of the vehicle and the greater the vehic le's
we ight, the more energy that has to be "absorbed" in the crash .
Vehicle speed is the most significan t factor. If the speed doubles
from 15 to 30 mph (25 to 50 km/h), the energy increases 4 times! .,

Safety belts protect
People think it's possible to use the hands to brace the
body in a minor collision. It's simply not true!
Fi g. 133 Driver is

m an euver
Safety belts used properly can make a big difference . Safety belts
help to keep passengers in their seats, gradually reduce energy
levels applied to the body in an accident , and help prevent the
uncontrolled movement that can cause serious injuries. In addition,
safety be lts reduce the danger of being thrown out of the vehic le.
Safety belts attach passengers to the car and g ive them the benefit
of being s lowed down more gently or "softly" through the "give" in
the safety belts, crush zones and other safety features engineered
into today's vehicles . By "absorbing" the kinetic energy
over a
longer period of time, the safety belts make the forces on the body
more "tolerable" and less like ly to cause injury.
Although these examples are based on a frontal collision , safety
belts can also substantially reduce the risk of injury in other kinds
of crashes. So, whether you're on a long trip or just going to the
corner store, always buckle up and make sure others do, too. Acci ­
dent statistics show that vehicle occupants proper ly wearing safety
bel ts have a lower risk of being injured and a much better chance o f
surviving an accident . Proper ly using safety belts also greatly
increases the abi lity of the supplementa l airbags to do their job in a
collision. For this reason, wearing a safety be lt is legally required in
most countries including much of the United States and Canada . Although your Audi is equipped with airbags, you sti
ll have to wear
the safety belts provided . Fron t airbags, for example, are activated
only in some frontal collisions . T he front airbags are not activated in
all frontal col lisions, in side and rear collisions, in roll overs or in
cases where there is not enough dece leration through impact to the
front of the vehicle . The same goes for the other airbag systems in
your Audi . So, always wear your safety belt and make sure
every ­
body in your vehic le is properly restrained! •
Important safety instructions about safety
belts
Safety belts must always be correctly positioned across
t he strongest bones of your body.
Always wear safety belts as illustrated and described in
this chapter.
Make sure tha t your safe ty belts are a lways ready for use
and are not damaged .
& WARNING
