On slopes, activate the parking brake first and
then move the selector lever to the P posit ion.
Aut omatic transm issio n
This prevents too much stress from being placed
on the locking mechanism .
A WARNING ,-
-The vehicle can also roll when the engine is
stopped.
- Unintended vehicle movement can cause se­
rio us injury.
- Never leave your vehicle with the engine
running while in gear . If you must leave your
veh icle when the engine is running, activate
the park ing brake and move the selector lev­
er to P .
- Power is still transmitted to the wheels
when the engine is runn ing at idle . To pre­
vent the vehicle from "creep ing", you must
keep your foot on the brake when the eng ine
is running and the se lector lever is in D/S or
R or "tiptronic" mode is selected.
- Do not press the accelerator pedal when
changing the se lector lever position while
the vehicle is stationary and the eng ine is
r u nning .
- Never sh ift into R or P while driving ,
- Before driving down a steep s lope, reduce
your speed and sh ift into a lower gear with
" t ipt ronic ".
- Do not ride the brakes or press the brake pedal too ofte n or too long whe n driving
down a hi ll. Constant brak ing causes the
b rakes to overhea t and substantially re­
duces braking performance, increases brak­ ing distance or causes comp lete fai lure of
the brake system.
- To prevent the vehicle from ro lling back
when stopping on inclines, always ho ld it in
p lace with the brake pedal or parking brake.
- Never hold the vehicle on an incline with a
slipping clutch. The clutch opens automati­
cally when it becomes too hot from the
overload. An ind icator lamp@] illuminates
and a driver message appears¢
page 87
when the clutch is overloaded .
-If the engine must remain running, never
have any dr iving posit ion engaged when
checking under the hood . Make sure these­
lecto r lever has secu rely engaged and is
locked in P with the parking brake set

using the shift paddles, move the s elector lever
to the right out of the 0/5 position.
The t ransmission automatically shifts up o r down
before critica l engine speed is reached.
The transmission only allows manua l shift ing
when the engine speed is within the permitted range .
@ Tips
-When you sh ift into the next lower gear, the
transmission will downshift only when there i s no poss ibility of over -revving the engine.
- When the kick-down comes on, the trans­
mission will sh ift down to a lower gear, de­
pending on vehicle and engine speeds .
- Tiptronic is inoperat ive when the transmis­
s ion is in the fa il-safe mode .
Kick-down
Appl ies to vehicles: with S tro nic/t iptronic
Kick-down enables maximum acceleration.
When you depress the accelerato r pedal beyond
the resistance po int, the automatic transm iss ion
downshifts into a lower gear, depend ing o n ve hi­
cle speed and engine speed. The upsh ift into the
nex t higher gear ta kes place once the maximum
specified engine speed is reached .
A WARNING
Please note that the drive wheels can spin if
kick-down is used on a smooth slippery road -
there is a risk of sk idding.

Audi adaptive cruise control and braking guard
Audi braking guard
Description
Applies to vehicles: with Audi adaptive cruise co ntrol
F ig. 103 Instrument cluste r: app roac h warn ing
Braking guard uses a radar sensor. It also func­
tions within the limits of the system when adap­
tive cruise control is switched off .
What can Audi braking guard do?
When detected in time, the system can assess
situations when a vehicle ahead brakes suddenly
or if your own vehicle is traveling at a high speed
and approaching a vehicle up ahead that is mov ­
ing more slowly . Braking guard does not react if it
cannot detect the s ituation .
The system advises you of various situations:
- The
distance warning is given if you are too
close to the vehicle ahead for a long time. If the
vehicle ahead brakes sharply, you will not be
able to avoid a collision. The indicator light.
in the d isplay comes on .
- The
approach warning is given when a detected
vehicle up ahead in your lane is moving much
more slowly than you are or if it brakes sharply .
When this warning is g iven, it may only be pos­
s ible to avoid a co llision by swerving or braki ng
sharply. The indicator light . and indicator in
the display will warn yo u about the danger
c> fig. 103. You wi ll also hear an acoust ic signa l.
If you do not react fast enough or do not react at
all to the situation, Braking guard will intervene
by braking and the message
braking guard inter-
~ vention will appear.

This is not available in som e count ries. rl
- If a collision is imminent, the system wi ll first
provide an
acute warning by briefly and sharply
app ly ing the brakes.
- If you do not react to the acute warning, brak­
ing guard can brake within the limits of the sys­
tem. This reduces the vehicle speed in the event
of a collision.
- At speeds under 20 mph (30 km/h), the system
can initiate a complete deceleration shortly be­
fore a collisionl).
- If the braking guard senses that you are not
braking hard enough when a collision is immi­
nent, it can increase the braking force.
Which functions can be controlled?
You can switch braking guard and the distance/
approach warning on or off in the radio or MMI
c> page 96, Settings in the radio/MM! .
A WARNING
-
Lack of attention can cause collisions, other
accidents and serious personal injuries. The b raking guard is an ass ist system and cannot
prevent a collis ion by itself. The driver must
always intervene. The driver is always respon­
sib le for b ra kin g at the correct time.
- Always pay close attent ion to traffic, even
when the braking guard is switched on. Be
ready to intervene and be ready to take com­
p lete control whenever necessary. Always
keep t he safe a nd legal distance between
your vehicle and vehicles up ahead.
- Braking guard works within limits and will
not respond outside the system limits, for
examp le when approaching a stopped vehi­
cle or stationary obstacle (end of a traffic
jam or vehicle that has broken down in traf­
f ic).
- Always remember that the radar sensor for
the braking guard works on ly w ithin defined
detection and range limits that may prevent
the proper detection of other vehicles.
- The radar sensor's funct ion and range can
be reduced by ra in, snow and heavy spray.
Moving vehicles up ahead may not be

Electronic Stabilization
Control (ESC)
Description
ESC helps to improve road holding and vehicle
dynamics to help reduce the probability of sk id­
d ing and loss of veh icle control.
It works only
when the engine is runn ing . ESC detects certain
d ifficult driving situations, including when the ve­
h icle is beginn ing to sp in (yaw) out of control and
he lps you to ge t the vehicle back u nder cont rol by
selectively braking the wheels, and/or reducing
engine power and providing steering assistance
to help hold the vehicle on the driver's intended
course. The indicator light
liJ in the instrument
cluster blinks when ESC is taking action to help
you control the veh icle.
ESC has limitations. It is important to remember
that ESC cannot overcome the laws of physics. It
will not always be able to help out under all con­
d itions you may come up against. For example,
ESC may not always be able to help you master
situations where there is a sudden change in the
coefficient of friction of the road surface. Whe n
there is a section of d ry road that is s uddenly cov ­
ered wi th wa ter, s lush or snow, ESC cannot per­
form the same way it wou ld on the d ry surface . If
the vehicle hydroplanes (rides on a cushion of wa ­
ter instead of the road surface), ESC wi ll not be
ab le to he lp you steer the veh icle because contact
with the pavement has been i nterrupted and the
ve hicle cannot be braked or steered. Dur ing fast
cornering, particula rly on w inding roads, ESC
cannot a lways deal as effect ively with d iff icu lt
d riving situat ions than at lower speeds. When
towing a trailer, ESC is not able to he lp yo u regain
con trol as it wou ld if yo u were not towing a trail­
er .
A lways adjust you r speed and dr iving style to
road, traffic and weather conditions. ESC cannot
override the vehicle's physical limi ts, increase the
170
available traction, or keep a vehicle on the road if
road departure is a result of driver inattention .
Instead, ESC improves the possibility of keeping
the ve hicle under control and on the road dur ing
extreme maneuvers by using the dr iver's steering
i nputs to help keep the vehicle going in the in­
tended direction. If you are traveling at a speed
that causes you to run off the road before ESC
can p rov ide any assistance, you may not expe ri­
ence the benefi ts of ESC.
ESC is switched o n all the time. In ce rtain s itua­
tions when you need less traction, you can switch
off ASR by p ress ing the button [!]¢
page 171,
fig. 153 or ¢page 171, fig. 154. Be s ure to
swi tch ASR on again when you no longe r need
l ess traction .
The following system s are integrated in the ESC:
Anti- lock braking s ystem (ABS )
ABS prevents the wheels from locki ng up when
braking. The vehicle ca n still be steered even dur­
i ng hard braki ng . Apply steady pressure to the
brake pedal. Do not pump t he pedal. A pu lsing in
t h e b ra ke peda l ind icates that the system is he lp­
i ng yo u to b ra ke the vehicle.
Brake assist system
The brake ass ist system can decrease brak ing dis ­
ta nce. It increases braking power when the d river
presses the bra ke peda l quickly in emergency sit­
u at ions. You must press and hold t he b ra ke peda l
u nt il t he s ituation is ove r. In vehicles with adap­
tive cru ise contro l*, the bra ke assist system is
more sensitive if the distance detected to the ve ­
hicle ahead is too sma ll.
Anti-slip regulation (ASR )
ASR reduces eng ine power when the d rive wheels
begin to spi n and adap ts the force to the ro ad
cond it ions . This makes it eas ie r to start, acce le r­
ate and drive up hills.
Electronic differential lock (EDL)
The EDL bra kes whee ls that a re spinn ing and
t ransfers the dr ive power to the othe r drive wheel
o r whee ls if the ve hicle is equippe d wi th a ll-wheel
drive*. T his function is not available at higher
speeds .

Braking
What affects broking efficiency?
New brake pads
During the first 250 miles (400 km), new brake
pads do not possess their full braking effect, they
have to be "broken in" first¢,&. . You can com­
pensate for this slightly reduced braking power
by pushing harder on the brake pedal. Avoid
heavy braking loads during the break-in period.
Operating conditions and driving habits
The brakes on today's automobiles are still sub­
ject to wear, depending largely on operating con­
ditions and driving habits~,&. . On vehicles that
are either driven most ly in stop-and -go city traf­
fic or are driven hard, the brake pads should be
checked by your authorized Audi dealer more of­
ten than specified in the
Warranty & Mainte­
nance booklet .
Failure to have your brake pads
i nspected can result in reduced brake perform­
ance .
On steep slopes, you should use the braking ef­
fect of the engine . This way, you prevent unnec­
essary wear on the brake system. If you must use
your brakes, do not hold the brakes down contin­
uously. Pump the brakes at intervals.

Smart Technolog y
Clean off accumulated salt coating from
brake discs and pads w ith a few carefu l
brake applications .
- If you damage the front spoiler, or if you in­
stall a d ifferent spoiler, be sure the air flow
to the front brakes is not obstructed. Other­
wise the brake system could overheat reduc ­
ing the effectiveness of the entire brake sys­
tem.
- Failure of one brake c ircuit will impair the
braking capab ility result ing in an increased
stopp ing distance. Avoid driving the veh icle
and have it towed to the nearest autho rized
Audi dealer or qualified workshop.
- Never let the vehicle ro ll to a stop with the
engine shut off .
- If the brake booster is not work ing, the
brake pedal must be pressed considerably
harder to make up for the lack of booste r as­
sistance .

Economical and environ­
mentally-friendly driving
General
Your personal style of driving will determine the
economy of your vehicle, as well as exhaust and
noise levels.
Fu el economy, environmental impact , and wear
on your engine, brakes and tires largely depend
on three factors:
- your persona l dr iving style
- operating conditions
- technical limitations
If you anticipate what you need to do next and
drive economically, you can easily cut your fuel
consumption by 10-15 percen t. This sec tion will
give you some tips on how you can help the envi ­
ronment and your pocketbook .
(!) Tips
The consumpt ion estimates as published by
ENVIRONMENTAL PROTECTION AGENCY (EPA)
and Transport Canada may not correspond to
your actual consumption on the road, which
w ill vary depending upon vehicle load and
speed, road and weather conditions, trip
length, etc.
Drive smoothly and keep a lookout ahead
Vehicles use the most fuel when they are acceler­
ating.
" Avoid unnecessary accelerating and braking.
Vehicles use the most fuel when they are acceler ­
ating . If you anticipate what is going to happen
next, you will need to brake less and, thus, accel­
e rate less. Let the vehicle coast whenever possi­
ble - for example when yo u see that the next traf­
fic light is red .
Driving and the environment
Avoid full throttle
Driving at moderate speeds saves fuel and im­
proves your mileage .
"Try and keep well below your car's maximum
speed.
Acce lerat ing gently reduces fue l consumption,
engine wear, and does not disturb the environ­
ment .
Fuel consumption, exhaust emissions and engine
noise increase disproportionately at high speeds.
If you drive at approximate ly three quarters of
top speed, fuel consump tion will be reduced by
one half. Never drive faster than the posted
speed l imit and weather cond itions permit .
Reducing unnecessary idling
Even when your car is jus t idling it burns up fuel.
" Shut the eng ine off when you are not driving
the vehicle.
" Do not warm up the vehicle by lett ing the en-
gine run at idle.
It makes sense to shut off the engine in traffic
jams, when wa iting for tra ins to pass a t railroad
crossings, or at traffic lights that have long waits
on red . Turning the engine
off for just 30-40 sec ­
onds saves more fue l than is burned starting the
. . engine again.
It takes a long t ime for the engine to warm up
fully when it is running at idle. However, wear
and noxious emissions are especially high when
the engine is warming up. So you should drive
away as soon as you sta rt the engine and avoid
running at high rpms wh ile the engine is st ill
warming up.
(D Note
Do not leave engine idling unatt ended afte r
starting .
If warning lights should come on to
indicate improper operation, they would go
un heeded . Extended idling also produces
heat, which could result in overheating or oth­
er damage to the vehicle or other property.
