You can determine for yourself if the engine
will stop or not by reducing or increasing the
amount of force you use to press the brake
pedal. For example, if you only lightly press
on the brake pedal in stop-and and-go traffic
or when turning, the engine will not switch off
when the vehicle is stationary. As soon as you
press the brake down harder, the engine will
switch off.

The Automatic Shift Lock only functions when
the vehicle is stationary or at speeds below
1 mph (2 km/h).
At speeds above about 1 mph (2 km/h) the
Automatic Shift Lock is automatically deacti­
vated in the N position.
A time delay element prevents the se lector
l eve r from locking when it is moved thro ugh
the N position (going from R to 0/5). The lock­
ing e lement will lock the selector lever if the
lever is left in N (Neutral) for more than ap­
prox imately 2 second, without the brake ped­
al being pressed.
R elease button
The release button on the selector lever pre ­
vents the lever from being accidenta lly shifted

110 Automatic Tran sm iss ion
multitronic transmission : Your vehicle is
equipped with
hill hold assist allowing you to
start while on an incline. The system is acti­
vated when the brake pedal is pressed down
and held
f o r a few s econds . The brake pres­
sure will hold for
a moment after the brake
pedal loosens to prevent the veh icle from roll­
ing backwards whi le starting up .
A WARNING
- The veh icle can also roll when the engine
is stopped.
- Unintended veh icle movement can cause
serious injury .
- Never leave your vehicle with the eng ine
running wh ile in gea r. If you must leave
yo ur vehicle when the engine is running,
act ivate the park ing brake and move the
selector lever to P .
- Power is st ill transmitted to the whee ls
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 pos ition
wh ile the vehicle is stat io nary and the
engine is running .
- Never shift into R or P wh ile driving .
- Before driv ing 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 dr iving
down a hill. Constant braking causes the
brakes to overheat and substant ially re­
duces b raking performance, inc reases
braking distance or causes comp lete fail­
ure of the brake system.
- T o prevent the veh icle from rolling back
when stoppi ng on incl ines, always hold it
in place with the brake peda l or parking
brake.
- Never hold the veh icle on an incl ine with
a slipping clutch. The clutch opens auto ­
matically when it becomes too hot from the overload. An indicato
r lamp
ml illu­
minates and a driver message appears
¢ page 112 when the clutch is overload­
ed.
- If the engine must remain running, never
have any driving posit io n engaged when
checking under the hood . Make sure the
selector lever has securely engaged and is locked in P w it h the park ing brake set
¢ page 222 . Otherwise, any increase in
eng ine 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 incl ine , do not try
t o hold the vehicle in place by pressing
the acce lerator pedal while a driving gear
is se lected. This can cause the transmis­
sion to overheat and can damage it. Acti­
vate the parking brake or press the brake
peda l to prevent the vehicle from roll ing.
- S tronic- and tiptronic transmission : A l­
lowing the vehicle to ro ll when the en­
gine is stopped and the selector lever is
in N will damage the transmission be­
cause it is not l ubricated unde r those cir­
cumstances.
{!) Tips
For safety reasons, the parking brake is re­
l eased automatically only when the d riv­
er's safety belt is engaged in the buckle.
Hill descent control
The hill descent control system assists the
driver when driving down declines.
Hill descent contro l is activated when these ­
lector lever is in D/S and you press the brake
pedal. The transmission automatically selects
a gear that is su itable fo r the incline. H ill de­
scent contro l tries to ma inta in the speed ach­
ieved at the time o f braking, within phys ica l
and technical limitations. If may sti ll be nec -
essary to adj ust the speed with the brakes . ..,..

Always apply brakes early. When driving
downhill, shift into a lower gear to use the en­
g ine braking effect to slow the vehicle . Use of
the brakes a lone can cause them to overheat
and fail.
Air suspension*
When driving with a trai ler, activate the trailer
mode of the air suspension. Switch the air
suspension trailer mode on when you are tow­
ing a trailer. This will limit the regulation by
the air suspension while driving. Select in the
MMI:
! CARI function button> (C ar) * systems
control button > Vehicle settings > Air susp.:
towing > On .
Coolant temperature
The coolant temperature gauge¢ page 11
must be observed carefully. The coolant tem­
perature can increase if you drive on long in­
clines in a low gear at high engine speeds . Re­
duce your speed immed iately if the LEDs in
the top pa rt of the display turn on.
For more information about indicator lights,
refer to. ¢
page 16 .
A WARNING
Anyone no t properly restrained in a mov­
ing veh icle is at a much greater ris k in an
accident . Never let anyone ride in your car
who is not properly wearing the restraints
provided by Audi .
Trailer towing tips
Important to know
Your vehicle handles differently when tow ing
a trailer because of the addit ional weight and
d ifferent weight distribution . Safety, perform­
ance and economy w ill greatly depend on how
carefully you load your trailer and operate
your rig.
Before you actually tow your trailer, practice
M N turning, stopping and backing up in an area 0
~ away from traffic. Keep practicing until you
~ have become comp lete ly fam iliar with the way 1.1'1 ,...., 1.1'1 ,....,
Trailer towing 207
your vehicle-trai ler combination behaves and
responds.
Backing up is difficult and requires practice .
Backing up with a trailer generally req uires
steering action opposite to that when backing
up your vehicle without a trai ler.
Maintain a greater distance between your ve­
hicle and the one in front of you. You will need
more room to stop. To compensate for the
trailer , you wi ll need a larger than normal
turning rad ius.
When passing, remember that you cannot ac­
ce lerate as fast as you norma lly would be­
cause of the added load. Make sure you have
enough room to pass . After passing, allow
plenty of room for your trailer before chang­
ing lanes again .
Avoid jerky starts, sharp turns or rapid lane changes.
(D Tips
- Do not tow a trailer during the break-in
period of your vehicle.
- If you tow a trailer, your Audi may re­
quire more frequent maintenance due to
the extra load ¢
page 292.
Parking on a slope
Do not park on a slope with a trailer. If it can­
not be avoided, do so only after doing the fol­ lowing:
When parking:
.,. App ly the foot brake .
.,. Have someone p lace chocks under both the
vehicle and the trailer wheels.
.,. With chocks in place, slowly release the
brakes until the wheel chocks absorb the
load .
.,. Turn the wheels towards the curb.
.,. Apply the parking brake .
.,. Select the P selector lever posit ion.
When re starting after parking:
.,. App ly the foot brake.
.,. Start the engine.
