Steering
Manually adjustable steering wheel
The steering wheel position is fully adjustable
up and down and forward and back.
Fig. 87 Lever under the steer ing column
First, adjust the driver's seat correctly.
• Pull the lever
Q fig . 87 <=> ,& .
• Move the steering wheel to the desired posi­
t ion.
• Push the lever against the steering column
until it locks.
There must be at least 10 inches (25 cm) be­
tween your chest and the center of the stee~
ing wheel.
If you cannot sit more than 10 in­
ches (25 cm) from the steering wheel, see if
adaptive equipment is available to help you
reach the pedals and increase the distance
from the steering wheel.
For detailed information on how to adjust the
driver's seat, see
<::)page 61.
& WARNING
Improper use of steering wheel adjust­
ment and improper seating position can
cause serious personal injury.
- Adjust the steering wheel column only
when the vehicle is not moving to pre­
vent loss of vehicle control.
- Adjust the driver's seat or steering wheel
so that there is a minimum of 10 inches
(25 cm) between your chest and the
steering wheel
c> page 113, fig . 131. If
you cannot maintain this minimum dis-
On the road 73
tance, the airbag system cannot protect
you properly.
- If physical limitations prevent you from
sitting 10 inches (25 cm) or more from
the steering wheel, check with your au­
thorized Audi dealer to see if adaptive
equipment is available.
- If the steering wheel is aligned with your
face, the supplemental driver's airbag
cannot provide as much protection in an
accident . Always make sure that the
steer ing whee l is aligned with your
chest.
- Always hold the steering whee l w ith your
hands at the 9 o'clock and 3 o'clock posi­
tions to reduce the risk of persona l injury
if the driver's airbag dep loys .
- Never hold the steering wheel at the 12
o'clock position or with your hands inside
the steeri ng wheel rim or on the steering
wheel hub. Holding the steering wheel
the wrong way can cause serious injuries
to the hands, arms and head if the driv­
er's airbag deploys.

Switching the ignition on/off
If you would like to switch the ignition on
without starting the engine, follow these
steps:
• Insert the key into the ignition lock .
• Press the key briefly
without pressing the
brake pedal.
• To switch the ignition off, press the key
again.
When starting the engine, major electrical
loads are switched off temporarily.
You can only remove the key with the ignition
switched off.
If the engine should not start immediately,
the starting process is automatically stopped
after a short time. Repeat starting procedure .
A WARNING
- Never allow the engine to run in confined
spaces -danger of asphyxiation.
- Never remove the ignition key from the
ignition look while the vehicle is moving.
Otherwise, the steering lock could sud­
denly engage and you would not be able
to steer the vehicle.
- Always take the key with you whenever
you leave your vehicle. Otherwise, the
engine could be started or electrical
equipment such as the power windows
could be operated. This can lead to seri­
ous injury.
- Never leave children or persons requiring
assistance unattended in the vehicle. The
doors can be locked using the remote
transmitter, preventing people from es­ caping from the vehicle on their own in
the event of an emergency . Depending
on the time of year, people inside the ve­
hicle can be exposed to very high or very
low temperatures.
(D Note
Avoid high engine rpm, full throttle and heavy engine loads until the engine has
reached operating temperature -other­
wise you risk engine damage.
@ For the sake of the environment
Do not let the engine run while parked to
warm up. Begin driving immediately. This
reduces unnecessary emissions.
(D Tips
- If the key cannot be removed from the
ignition lock, you have to pull the me­
chanical key out of the master key in or­
der to be able to lock the vehicle
¢page 33 .
-After starting a cold engine, there may
be a brief period of increased noise be­
cause the oil pressure must first build up
in the hydraulic valve adjusters. This is
normal and not a cause for concern.
- If you leave the vehicle with the ignition
switched on, the ignition will switch off
after a certain period of time. Please
note that electrical equipment such as
exterior lights will switch off as well
when that happens.

.., Pull on the switch @ c.> fig. 92 to apply the
parking brake. The indicator lights in the
switch and. (USA models)/. (Cana-
da models) in the instrument cluste r ill umi­
nate. ..,
With the ignition switched on, step on the
brake peda l or the accelerator pedal and
press the switch @ at the same time to re ­
lease the parking brake . The indicator lights
in the switch and. (USA mode ls)/ . (Can­
ada models) in the instrument cluster go

Your vehicle is equipped with an electrome­ chanical parking brake. The parking brake is
designed to prevent the veh icle from rolling
u nintentionally and replaces the hand brake.
In add ition to the normal functions of a tradi­
t ional hand brake, the electromechanical
parking brake provides various convenience
and safe ty funct ions .
When starting from rest
-The integral start ing ass ist helps you when
driving by automatically releasing the park­
ing brake
c> page 79, Starting from rest .
- When start ing o n inclines, the starting as­
sist prevents the vehicle from unintentional­
ly rolling back. The braking force of the
pa rking brake is not released until suffic ient
driving force has been bui lt up at the
wheels.
Emergency brake function
An emergency brake ensures that the veh icle
can be slowed down even i f the normal brakes
fail ¢ page 79, Emergency braking.
A WARNING
If a drive rang e is engaged with the vehicle
stationary and the engine running, yo u
must in no instance accelerate carelessly.
Otherwise the vehi cle wi ll start to move
immediately -risk of an accident.
(0 Tips
-If the parking brake is applied with the
ign ition switched off, the ind icator lights
in the switch and - (USA models) .
(Canada mode ls) in the instrument clus­
ter will go out after a certain period of

Transmission S tronic
Introduction
The automat ic transm iss ion is controlled elec­
tronically. The transmiss ion upshifts or down­
shifts automatically depend ing on which drive
p rogram is se lected.
When a
moderate driving sty le is used, the
transmission selects the most econom ica l
d riving mode.
It w ill then change up early and
de lay the downshifts to g ive better f uel econ ­
omy .
The transmis sion swi tches to a sporty mode
after a k ick-down or when the dr iver uses a
sporty driving sty le characterized by quick ac­
celerator peda l movements, heavy accelera­
tion, frequent changes in speed and traveling
at the maximum speed.
If desired, the drive r can a lso se lect the gears
manually ( tiptronic mode ) ~ page 87.
The S tronic is a dual-clut ch tra nsmission.
P ower is transfe rred using two clutches that
work independently from one another . They
rep lace the torq ue converter used in conven­
tional automatic transmiss ions and allow the
vehicle to accelerate without a noticeable in­
terruption in traction.
