The combust ion eng ine tu rns on and inter­
rupts
the enhanced electric d rive mode when
the vehicle is accelerated. The gray indicator
light
l!I also turns on in the disp lay. The en­
hanced electric drive mode resumes automati ­
cally once acceleration stops.
The enhanced e lectric drive mode is
deactivat­
ed if at least one of the following conditions is
met :
- The ign ition is turned
off.
- Th e 1.:1"1 button is pressed again.
- The high voltage battery charge level is low .
- The vehicle speed is higher than approxi -
mately 62 mph (100 km/h).
- The S selector lever position or tiptronic
mode is selected .
- ESC offroad mode or hill descent assist is
switched on .
T he
ld" I button must be pressed to reactivate
it .
Start-Stop function
The combustion engine is operated on ly as
needed. Generally, the combustion engine
turns
off when the vehicle is stationary and
the high voltage battery powers the electrical
vehicle systems.
The purpose of automatica lly shutting the
combustion engine
off in hybrid drive mode is
to save fuel. All of the important veh icle sys­
tems, such as steering, brakes and the A/C
system, cont inue to remain active. In some
cases , systems may require the combustion
engine to cont inue running when the vehicle
is stationary. When dr iv ing in congested traf­
fic for long per iods of time, the comb ustion
engine w ill cycle on when the vehicle is sta­
tionary to keep the high voltage battery
charged.
Gliding
I f the gas pedal is not pressed and the D posi­
tion is selec ted, the combustion engine re-
Hybrid 101
mains turned off up to speeds of approxi ­
mately 99 mph (160 km/h). Driving conserva­
tive ly like this can reduce fuel consumption.
Energy recovery (recuperation)
When braking, the electric motor will act as a
generator creating e lectric energy that is then
stored in the high voltage battery. This also
occurs when the ve hicle is coasting or driving
downhi ll. The combustion engine is automati­
cally turned
off i n this case.
The vehicle is braked with the electric motor
by applying ear ly and even pressure to the
brakes and using short pedal movements
¢
page 98, fig. 108 @. By doing this, a large
amount of the kinetic energy is recovered and
may be stored as electric energy in the high
voltage battery . During heavy braking, the
convent ional brakes are also act ivated
¢ page 98, fig. 108 @.
The energy recovery is shown in the MMI dis­
play ¢
page 104.
Automatic start of the combustion engine
Various operating conditions cause the com­
bust ion engine to start automat ically :
- The high voltage battery charge leve l is low.
- The temperature of the combustion engine
is low.
- The temperature of the catalytic converter is
low .
- The power output needed for the A/C sys-
t em is high.
- The vehicle speed is high.
- The vehicle acceleration is high.
- The inclin e is steep.
- High charge level for the high voltage bat-
tery when coasting. In th is case, the h igh
voltage battery cannot absorb any more en ­
ergy and so the electric motor cannot slow
down the veh icle. The combustion engine
tu rns on (engine brake). In this situation the
h igh voltage battery will show a Max charge.

Intelligent technology Notice about data
recorded by vehicle
control modules
Your vehicle is not equipped with an Event Da­
ta Recorder (EDR), installed by some manu­
facturers for the express purpose of capturing
data for retrieval after an accident or crash
event. EDR's are sometimes called "crash re­
corders".
Some state laws restrict the retr ieval or down­
loading of data stored by EDR's that were in­
stalled in a vehicle for the express purpose of
retrieving data after an accident or crash
event without the owner's consent.
Although your vehicle is not equipped with an
EDR, it is equipped with a number of electron­
ic control modules for various vehicle systems
such as, for examp le, engine function, emis­
sion control, as well as for the airbags and
safety belts.
These electronic control modules also record
vehicle-related data during norma l vehicle op­
eration for diagnostic and repair purposes.
The recording capacity of the electronic con­
trol modules is limited to data (no sound is re­
corded) and only a small amount of data is ac­
tually recorded over a very limited period of
time and stored when a system fault or other
condition is sensed by a control unit. Some of
the data then stored may relate to vehicle
speed, direction, braking as we ll as restraint
system use and performance in the event of a
crash or other condition. Stored data can only be read and downloaded with special equip­
ment.
Electronic Stabilization
Control (ESC)
Description
The Electronic Stabilization Control (ESC) rein­
forces driver safety. It reduces the risk of slip ­
ping and improves driving stability. ESC de­
tects critical s ituations such as the vehicle
Intelligent technology 197
oversteering and understeering or the whee ls
spinning . The vehicle is stabilized by applying
the brakes or reducing eng ine torque . Once
the ESC is active, the indicator light
G1 blinks
in the instrument cluster.
ESC includes the anti-lock brake system (ABS),
brake assist system, anti-slip regulation
(ASR), electronic differential lock (EDL), dy­
namic steering*, hill descent assist and selec­
tive wheel torque control.
Anti-lock braking system (ABS)
ABS prevents the whee ls from locking up
when braking . The vehicle can still be steered
even during hard braking. App ly steady pres­
sure to the brake pedal. Do not pump the ped­
al. A pulsing in the brake pedal indicates that
the system is helping you to brake the vehicle .
Brake assist system
The brake assist system can decrease braking
distance. It increases braking power when the
driver presses the brake pedal quickly in emer­
gency situations . You must press and hold the
brake pedal until the situation is over . In
vehicles with adaptive cruise control*, the
brake assist system is more sensitive if the
distance detected to the vehicle ahead is too
small.
Anti-slip regulation (ASR)
ASR reduces engine power when the drive
wheels beg in to sp in and adapts the force to
the road conditions. This makes it easier to
start, accelerate and drive up hill s.
Electronic differential lock (EDL)
The EDL brakes wheels that are spinning and
transfers the drive power to the othe r whee ls .
T his function is available up to about 78 mph
(125 km/h) .
In extreme cases, EDL automatically switches
off to help keep the brake on the braked wheel
from overheat ing. EDL will switch on again au­
tomatically when conditions have returned to
normal.

Dynamic ste ering *
On vehicles with dynamic stee ring* , ES C helps
stabilize the st eering in critical s ituations .
Selective wh eel torque c ontrol
The selective whee l torque control operates
when dr iv ing through curves . T he front wheel
on the inside of the curve or both wheels on
the inside of the curv e are braked selective ly
as needed. This m inimizes sliding in the front
wheels and allows for more pr ecise driving
through curves . T he system may not act ivate
when driving in wet or snowy cond itions .
A WARNING
-ESC, ABS, ASR, EDL dynamic steering"
and the se lective wheel torque control
cannot overcome the laws of physics .
Th is is especially important on slippery
or wet roads.
If the systems begin act ing
to stabilize yo ur vehicle , you sho uld im­
med iately change your speed to ma tch
the road and traffic condit ions. Do not
let the increased safety provided by
these systems tempt you to take risks. Do ing so wi ll increase the risk of a loss of
vehicle control, collision and serious per­
sonal injuries .
- Always adapt your speed to road, traff ic
and weather condit ions. The risk of Los-
-
ing cont ro l of the veh icle increases when
dr iv ing too fast, especially th rough
c u rves and on slippery o r wet roads, and
when d riving too close to vehi cles up
ahead. ESC, A BS, the brake assis t sys­
tem, AS R, EDL, dynamic steering* and
the se lective wheel torque control can­
not prevent collis ions.
-Always acce lerate with specia l care on
even, smooth surfaces s uch as those that
are wet or covered with ice and snow.
The drive wheels can spin even with
these ass istance systems that cannot al­
ways help to reduce the risk of loss of ve ­
hicle control.
(D Tips
- ABS and ASR only wo rk correctly when
all four wheels are equipped with identi­
cal tires. Different tire si zes can lead to a
reduction in engine power .
- Yo u may hear noises when the systems
described are working.
- If the ind icator light
DJ or E (USA
mode ls)/ m] (Canada models) appears,
there may be a malfunction
q page 15 ,
q page 17.
-When i nstalling a factory -supplied roof
rack system on the roof railing, the ESC
will adapt itse lf to a different center of
gravity .
Switching on/off
ESC turns on automatically when you start
the engine.

Brake lining wear may be checked by visual in ­
spection of the condition of the brake pads
through the openings in the whee l. If neces­
sa ry, the wheel may be removed for this in­
spection

.&_ WARNING
=
- You should perform braking maneuvers
for the purpose of clean ing the brake
system on ly if road conditions permit.
Other road users must not be put at risk -
you may cause an acc ident!
- Before descending a steep grade, reduce
speed and shift transmiss ion into a lower
gear or lower driving range . Do not ride
the brakes or hold the pedal down too long or too often . This could cause the
brakes to get hot and dimin ish b raking
efficiency .
- Do not "ride the brakes" by resting your
foot on the pedal when you do not intend
to brake . Th is may cause the b rakes to
overheat, premat ure wear and increased
stopping distance .
- Under certain climat ic and operating
condit ions such as passing through wa­
ter , driving in heavy rain or after wash ing
the vehicle, the effectiveness of the brakes can be reduced. In winter, ice can
accumulate on the brake pads, linings,
discs and drums . Carefully apply brakes
Int ellig ent technolog y 201
for a test. Brakes will dry and ice coat­
ings w ill be cleaned off after a few care­
ful brake applicat ions.
- Driving for an extended period of time on
salt-covered roads without using your
brakes can also affect braking efficiency.
Clean off accumulated salt coating from
brake discs and pads with a few careful
brake applications.
- If you damage the front spoiler, or if you install a different spoiler, be sure the air
f low to the front brakes is not obst ruct­
ed. Otherw ise the brake system could
overhea t reducing the effectiveness of
the entire brake system .
- Failure of one brake circuit will impair
the braking capability resulting in an in­
creased stopping distance . Avoid driving
the vehicle and have it towed to the near­
est a uthori zed Audi dea ler or qualified
workshop.
- Never let the vehicle roll to a stop with
the engine shut off .
- If the brake booster is not working, for
examp le when towing your vehicle, or
because the brake booster has somehow
been damaged, the brake pedal must be
pressed considerably harder to make up
for the lack of booster assistance .

engine after this is finished, the steering
wheel will be easy to move. Re-initialization might be necessary if the steering wheel was
moved hard to the left and right while the ve­
hicle was not moving. The display turns off if
the initialization was successfu l.

Driving with your
quattro ®
With all-wheel drive, all four wheels are driv ­
en .
General information
With all-wheel dr ive, power is distributed to
all four wheels. This happens automatically
depending on your dr iving style and the road
conditions at the time . See also ¢
page 197.
A center different ial distr ibutes the dr iv ing
power var iably to the front and rear axle.
It
works together with selective wheel torque
control, which activates when driving through
curves
¢ page 198.
The all-wheel drive concept is des igned for
high engine power. Your veh icle is exception ­
ally powerfu l and has excellent driving charac­
teristics both under normal driving conditions
and on snow and ice. Always read and follow
safety precaut ions¢ &.
Winter tires
When driving in the winter, yo ur vehicle with
all -wheel drive has an advantage, even with
regular tires. In winter road conditions it may
be advisable to mount winter tires (or all-sea­
son tires) for improved driveability and brak­
ing: these tires must be mounted o n
all four
wheels .
See also¢ page 263, Winter tires.
Tire chains
Where tire chains are mandatory on certain
roads, this normally also app lies to veh icles
with all-wheel drive¢
page 264, Snow
chains.
Replacing wheels/tires
Vehicles with all -wheel drive must always
have tires of the same s ize. A lso avoid tires
with different tread depths. For deta ils see
page
o page 2 59, New tires and replacing
tires and wheels.
A WARNING
-Always adjust your dr iv ing to road and traf-
fic conditions. Do not let the extra safety
afforded by all-wheel drive tempt you into
taking extra risks.
- Altho ugh the all-wheel drive is very ef­
fective, always remember that braking
capacity is limited by tire traction. You
should therefore not d rive at excessive
speeds on icy or slippery road surfaces.
- On wet road surfaces, be careful not to
drive too fast because the front wheels
could begin to slide on top of the water
(aquaplaning). If this should occur, you

-Never mount used tires on yo ur vehicle if
yo u are not sure of their "previous histo­
ry." Old used tires may have been dam­
aged even though the damage cannot be
seen that can lead to sudden tire failure
and loss of vehicle control.
- If you notice unusual vibration or if the
vehicle pulls to one side when d riving, al­
ways stop as soon as it is safe to do so
and check the wheels and tires for dam­
age .
