lecting gear
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 selector lever from locking when it is moved through
the N position (going from R to D/S). The lock­
ing element will lock the selector lever if the
lever is left in N (Neutral) for more than ap­
proximately 2 seconds, without the brake ped­
al being pressed.
Release button
The release button on the selector lever pre­
vents the lever from be ing accidentally shifted
into certain positions. Depending on the direc­
tion of the shift, the selector lever locks at dif­
ferent positions. The positions are highlighted

der to adjust the gears to the driving condi­
tions by hand ¢
page 96.
On s lopes, 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 yo u to start while on an incline. The sys ­
tem is activated when the brake pedal is
pressed down and he ld
for a few seconds . The
brake pressure will hold for
a moment after
the brake pedal loosens to prevent the vehicle
from roll ing backwards w hile 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
r un ning while in gear. If you must leave
your veh icle 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 runn ing 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 0/5 or R or "t iptronic" mode is
selected .
- Do not press the accelerator pedal when changing the selector lever position
while the veh icle is stationary and the
engine is running.
- Never shift into R or P while driving.
- Before driving down a steep s lope, 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
[O] illu­
minates and a driver message appears
¢ page 9 7 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 213, Engine compartment . Oth­
erwise, any increase in engine speed may
set the vehicle in motion, even with the
parking brake applied .
0 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 .

The hill descent control system assists the
driver when driving down declines .
Hill descent control is activated when these­
lector lever is in D/S and you press the brake
pedal. The transmission automatically selects
a gear that is suitable for the incline. Hill de­ scent control tries to maintain the speed ach­
ieved at the time of braking, within physical
and technical limitations. It may still be nec­
essary to adjust the speed with the brakes.
Hill descent control switches off once the de­
cline levels out or you press the accelerator
pedal.
On vehicles with the cruise control system*
¢ page 89 , hill descent control is also activat­
ed when the speed is set.
.&_ WARNING
-
Hill descent control cannot overcome
physical limitations, so it may not be able
to maintain a constant speed under all
conditions. Always be ready to apply the brakes.

Audi drive select Driving settings
Introduction
Appl ies to vehicles: wit h Audi drive select
Drive select provides the possibility to experi­
ence different types of vehicle settings in one
veh icle. For instance, using the three
Com­
fort, Auto and Dynamic modes, the driver can
switch from a sporty to a comfortab le driving
mode with the press of a button.
Addit ionally, in vehicles with
MM I*, the vehi ­
cle setup for
Individual* mode can be cus­
tomized by you. This makes it possib le to
combine settings such as a sporty engine tun­
ing with comfortable steering.
A WARNING
Improper use of the Audi drive select can
cause collisions, other acc idents and seri­
ous personal injury.
Description
Applies to vehicles: w it h Audi drive select
The vehicle setup in each mode depends on
the vehicle's features. However, the engine,
automatic t ransmission* and steering are al­
ways involved.
-
Engine and automatic transmission*
Depending on the mode, the engine and the
automatic transmission respond quicker or in
a more ba lanced manner to accelerator pedal
movements. In the sporty dynamic mode, the
automatic transmission shifts at higher RPMs .
Steering
The steering adapts in terms of steering effort
and steering ratios. Indirect steer ing that
moves easily, like the steering in comfort
mode, is best su ited to long dr ives on a high­
way. In contrast, dynamic mode prov ides
sporty, direct steering.
The follow ing applies to vehicles with dynam ic
steer ing*: the steering ratio changes based on
veh icle speed in order to maintain optimum
Audi drive select 113
steering effort for the driver at all times. This
sets the steering to be less sensitive at higher
speeds in order to provide improved vehicle
control. At reduced speeds, however, steering
is more direct in order to keep the steering ef­
fort as minimal as possible when the driver is
maneuveri ng the vehicle . At low and average
speeds, dynamic steering addit iona lly pro­
vides more responsive steering performance.
Adaptive dampers*
The adaptive dampers* use sensors to record
information regarding steering movements,
braking and acceleration operations by the
drive r, road surface, driving speed, and load.
T his makes it possible to adapt damp ing to
the driving situation virtually i n rea l time.
Drive select also makes it possible to satisfy
the desire for sporty suspension (Dynamic)
and comfortab le suspension (Comfort) with­
out giving up balanced tuning (Auto) .
Sport differential*
As a component of the all wheel dr ive system
(quattro ®)
q poge 191, the sport differential*
distributes the driving power to the rear axle
depending on the situation . The distribution
of power varies depending on the mode se­ lected. The goal is a high level of agility and
ability to accelerate on curves . The vehicle is
very respons ive to steering .
Audi adaptive cru ise control*
The behavior when accelerating can be adjust­
ed from comfortab le to sporty, depending on
the drive select mode. Adaptive cruise control
also responds to the driving behavior of the
vehicle ahead in a more conservative or sporty
manner .
Engine sound*
The sound of the engine is adapted to the se­
lected mode and ranges from subtle to sporty.
0) Tips
-In some models, the maximum vehicle
speed can only be reached in the
Auto
and Dynamic modes.

220 Checking and filling
-To reduce the risk of being burned, never
open the hood if you see or hear steam
or coolant escaping from the engine
compartment . Wait until no steam or
coolant can be seen or heard before care­
fully opening the hood .
- Keep children away from the engine com ­
partment .
- Never spill fluids on hot engine compo­
nents. They can cause a fire.
- Never touch the radiator fan. The auxili­
ary electric fan is temperature controlled
and can switch on suddenly.
- Never open the coolant reservoir cap
when the engine is still warm. The cool­
ant system is pressurized and hot cool­
ant could spray out.
- Protect your face, hands and arm from
steam or hot engine coolant by placing a
thick rag over the cap when you open the
coolant reservoir .
- Do not remove the engine cover under
any circumstances. This increases the
risk of burns.
- If work on the fuel system or the electri­
cal system is necessary:
- Always disconnect the battery.
- Never smoke or work near heaters or
open flames. Fluids in the engine com­ partment could start a fire.
- Keep an approved fire extinguisher im­
mediately available.
- To avoid electrical shock and personal in­
jury while the engine is running or being
started, never touch:
- Ignition cables
- Other components of the high voltage
electronic ignition system.
- If you must perform a check or repair
with the engine running:
- First, fully apply the parking brake,
move selector lever of automatic trans- mission to
"P" (Park); put manual
transmission in Neutral.
- Always use extreme caution to prevent
clothing, jewelry, or long hair from get­
ting caught in the radiator fan, V-belts
or other moving parts, or from contact­ ing hot parts . Tie back hair before
starting, and do not wear clothing that
will hang or droop into the engine .
- Minimize exposure to emission and
chemical hazards

A WARNING
You or your passengers could be injured
while changing a wheel if you do not fol­
low these safety precautions:
- If you have a flat tire, move a safe dis­
tance off the road. Turn off the engine,
turn the emergency flashers on and use
other warning devices to alert other mo­
torists.
- Make sure that passengers wait in a safe
place away from the vehicle and well
away from the road and traffic.
- To help prevent the vehicle from moving
suddenly and possibly slipping off the
jack, always fully set the parking brake
and block the wheel diagonally opposite
the wheel being changed with the fold­
ing chocks or other objects. When one
front wheel is lifted off the ground, plac­ ing the Automatic Transmission in "P"
(Park) will
not prevent the vehicle from
moving .
- Before you change a wheel, be sure the
ground is level and firm. If necessary,
use a sturdy board under the jack.
- Always store the vehicle tool kit, the
jack* and the replaced tire in the luggage compartment

Emergency situations
General
This chapter is intended for trained emer­
gency crews and working personnel who
have the necessary tools and equipment to
perform these operations.
Starting by pushing or
towing
(D Note
Vehicles with an automatic transmission
cannot be started by pushing or towing .
Starting with jumper
cables
If necessary, the engine can be started by
connecting it to the battery of another vehi­
cle.
If the engine should fail to start because of a
discharged or weak battery, the battery can be
connected to the battery of
another vehicle,
using a
pair of jumper cables to start the en­
g ine.
Jumper cables
Use only jumper cables of sufficiently
largecross section to carry the starter current
safe ly. Refer to the manufacturer's specifica­
tions.
Use only jumper cables with
insulated termi­
na l clamps which are distinctly marked:
plus(+) cable in most cases colored red
