emergency situation, or if the standard brakes
are malfunctioning or the pedal is obstructed.
> Pull and hold the ©) switch.
>» As soon as you release the (©) switch or acceler-
ate, the braking stops.
Pulling and holding the ©) switch while driving
the vehicle activates the emergency braking func-
tion. The hydraulic brake system will brake all
four wheels. The braking effect is similar to heavy
braking > A\.

ZA WARNING
— If a gear is engaged while the vehicle is sta-
tionary and the engine is running, do not
press the accelerator pedal inadvertently.
Otherwise, the vehicle will start to move im-
mediately and this could result in an acci-
dent.
— Emergency braking should only be used in
an emergency, when the when the standard
brake pedal is malfunctioning or obstructed.
During emergency braking, your vehicle will
brake similar to heavy braking. ESC and the
associated components (ABS, ASR, EDL) can-
not overcome the laws of physics. In corners

reduce the risk of injury, do not place your
foot under the brake pedal.
@) Note
— Never let the brakes “rub” by pressing the
pedal lightly when braking is not actually
necessary. This can cause the brakes to over-
heat and increases braking distance and
causes wear.

— Before driving on long stretches with steep
hills, reduce the vehicle speed and shift to a
lower gear to use the engine braking effect.
This reduces the load on the brakes. If you
need to brake additionally, brake in intervals
and not continuously.
G) Tips
— If you retrofit your vehicle with a front spoil-
er, wheel covers or similar items, make sure
that the air flow to the brakes is not ob-
structed. Otherwise the brake system can
overheat.
— Also refer to the information about brake
fluid > page 239.
Steering
Electromechanical steering supports the driver's
steering movements by electronically adapting
the power steering depending on the vehicle
speed. The settings depend on the selected Audi
drive select* mode.
Dynamic steering
Applies to: vehicles with dynamic steering
The driving dynamic and driving stability are in-
creased by the steering ratio based on the speed.
At reduced speeds, steering is direct in order to
provide agile steering behavior and keep the
steering effort as minimal as possible when the
driver is maneuvering the vehicle. This sets the
steering to be less sensitive at higher speeds in
order to provide improved vehicle control.
Messages
a Steering: malfunction! Please stop vehicle
The power steering may have failed. Adapt your
driving style immediately to compensate for the
fact that it may be more difficult to turn the
steering wheel, and stop your vehicle in a safe lo-
cation as soon as possible. Do not continue driv-
ing. See an authorized Audi dealer or authorized
Audi Service Facility for assistance.
a Steering: malfunction! You can continue
driving
There is a malfunction. Steering may be more dif-
ficult or more sensitive. Adapt your driving style.
Have the steering system checked immediately
by an authorized Audi dealer or authorized Audi
Service Facility. Please note that the red indicator
light may turn on after restarting the engine. Do
not continue driving if it does.
Dynamic steering: correcting steering wheel
Position
The steering is reinitializing. The steering wheel
will move easily after starting the vehicle. Reiniti-
alization might be necessary if the steering wheel
was moved while the engine was switched off.
The display turns off if the initialization was suc-
cessful.
@) Tips
— If there is a malfunction, the steering wheel
may be crooked when driving straight.
—Ifthe a or Ee indicator light only stays on
for a short time, you may continue driving.
All wheel drive (quattro)
Applies to: vehicles with all wheel drive
In all wheel drive, all four wheels are powered.
General information
In all wheel drive, the driving power is divided be-
tween all four wheels. This happens automatical-
ly depending on your driving behavior as well as
the current road conditions. Also see > page 86,
Electronic stabilization control (ESC).
The all wheel drive concept is designed for high
engine power. Your vehicle is exceptionally pow-
erful and has excellent driving characteristics
both under normal driving conditions and on >

snow and ice. Always read and follow safety pre-
cautions > A\.
Winter tires
By using all wheel drive, your vehicle has good
forward motion with standard tires in winter con-
ditions. However, in winter we recommend using
winter or all season tires on all four wheels, be-
cause this will improve the braking effect.
Snow chains
If there are snow chain laws, snow chains must
also be used on vehicles with all wheel drive
= page 259, Snow chains.

ZA WARNING
— Also, in vehicles with all wheel drive, adapt
your driving style to the current road and
traffic conditions. Do not let the increased
safety provided tempt you into taking risks,
because this increases the risk of an acci-
dent.
— The braking ability of your vehicle is limited
to the traction of the wheels. In this way, it
is not different from a two wheel drive vehi-
cle. Do not be tempted to accelerate toa
high speed when the road is slippery, be-
cause this increases the risk of an accident.
— Note that on wet streets, the front wheels
can “hydroplane” if driving at speeds that
are too high. Unlike front wheel drive vehi-
cles, the engine RPM does not increase sud-
denly when the vehicle begins hydroplaning.
For this reason, adapt your speed to the
road conditions to reduce the risk of an acci-
dent.

The rear spoiler retracts and extends. It can be
activated in various operating modes (manual
mode or automatic mode).
Automatic mode (normal operation)
— Automatic extension: this occurs when driving
faster than approximately 75 mph (120 km/h)
or at a certain engine compartment tempera-
ture.
— Automatic retraction: this occurs when driving
slower than approximately 22 mph (35 km/h)
or at a certain engine compartment tempera-
ture.
Manual mode
— Extending manually: briefly tap the > fig. 92
button to fully extend the rear spoiler.
— Retracting manually: when driving at speeds
below approximately 10 mph (20 km/h), press
and hold the button to retract the rear spoiler.
At speeds between 10 mph (20 km/h) and 62
mph (100 km/h), the rear spoiler will com-
pletely retract when you tap the button. You
cannot retract the rear spoiler if it extended
due to the engine compartment temperature.

faster than 85 mph (140 km/h). Drive immedi-
ately to an authorized Audi dealer or authorized
Audi Service Facility to have the malfunction re-
paired. The color of the indicator light depends
on the vehicle speed.

ZA WARNING
Driving at higher speeds without the rear
spoiler deployed can impair handling charac-
teristics, making the vehicle harder to control.
— Always make sure that the spoiler is de-
ployed when driving at speeds over 85 mph
(140 km/h). If the rear spoiler warning/indi-
cator light in the instrument cluster comes
on, the rear spoiler may not have deployed.
— Never drive at speeds higher than 85 mph
(140 km/h) if the spoiler is not deployed.
Have the spoiler inspected as soon as possi-
ble by an authorized Audi dealer or qualified
workshop.
— Always obey speed limits and other traffic
laws.
— Hot air from the engine compartment can
escape through the rear spoiler when it is
open and it could burn you.

ZA\ WARNING
Improper operation of the rear spoiler can
cause crushing injuries.
— Always make sure that nobody, especially
children, is in the way when the rear spoiler
is deployed or retracted.

©) Note
— Never push on the vehicle on the rear spoil-
er. This could cause damage.
— To prevent damage to the rear spoiler do
not lean or place anything on it.
—To reduce the risk of damage, only operate
the rear spoiler manually when the engine
compartment lid is closed and the moving
parts for the rear spoiler are not blocked.
G@) Tips
Clean the rear spoiler compartment every 2 to
3 months. To function correctly, the rear
spoiler must be free of ice, snow and leaves.
Energy management
Your vehicle is equipped with an intelligent ener-
gy management system for distributing electrici-
ty. This significantly improves the starting ability
and increases the vehicle battery life.
(i) Tips
— If you drive short distances frequently, the
vehicle battery may not charge enough
while driving. As a result, convenience func-
tions for electrical equipment may be tem-
porarily unavailable.
— The vehicle battery will gradually drain if
the vehicle is not driven for long periods of
time, or if electrical equipment is used
when the engine is not running. To ensure
that the vehicle can still be started, the
electrical equipment will be limited or
switched off.
Notice about data
recorded by the Event
Data Recorder and
vehicle control modules
Event Data Recorder
This vehicle is equipped with an Event Data Re-
corder (EDR). The main purpose of an EDR is to
record, in certain crash or near crash-like situa-
tions, such as an airbag deployment or hitting a
road obstacle, data that will assist in understand-
ing how a vehicle's systems performed. The EDR
is designed to record data related to vehicle dy-
namics and safety systems for a short period of
time, typically 30 seconds or less. The EDR in this
vehicle is designed to record such data as:
— How various systems in your vehicle were oper-
ating;
— Whether or not the driver and passenger safety
belts were buckled/fastened;
— How far (if at all) the driver was depressing the
accelerator and/or brake pedal; and,
— How fast the vehicle was traveling.
These data can help provide a better understand-
ing of the circumstances in which crashes and

Fuel has entered the engine oil, either due to low
outside temperatures or frequent short drives.
Drive until the engine is warm so that the fuel in
the engine oil will evaporate. Avoid high engine
speeds, full accelerating, and heavy engine loads
when doing this.
G) Tips
The oil pressure warning & is not an oil level
indicator. Always check the oil level regularly.
Checking the engine oil level
The engine oil level can be checked in the Info-
tainment system
Observe the safety precautions > A\ in General
information on page 229.
> Park your vehicle on a level surface.
> Let the engine run at idle.
> Wait approximately two minutes.
> Select in the Infotainment system: the [MENU
button > left control button > Service & checks
> Oil level


234
> Read the oil level in the display. Add engine oil
if the bar in the oil level indicator is just below
“min” > page 235.
C) Note
If the engine oil level is too low or too high,
there is a risk of engine damage.
G) Tips
The oil level indicator in the display is only an
informational display. If the oil level is too
low, a minimum oil warning appears in the in-
strument cluster. Add oil and close the engine
compartment lid. The current oil level is dis-
played in the Infotainment system the next
time the ignition is switched on.
G) Tips
— The engine oil consumption may be up to
1 quart per 600 miles (0.8 liter/1,000 km),
depending on driving style and operating
conditions. Consumption may be higher dur-
ing the first 3,000 miles (5,000 km). The
engine oil level must be checked regularly.
It is best to check each time you refuel your
vehicle and before long drives.
— Because of the lubrication and cooling of
the engine, combustion engines consume
oil. The oil consumption varies depending
on the engine and may change during the
service life of the engine. Engines generally
consume more oil at the beginning during
the break-in period. Then oil consumption
stabilizes after the break-in period.
— Under normal conditions, oil consumption
depends on the quality and viscosity of the
oil, the engine RPM, the climate conditions,
and the road conditions. The dilution of oil
from condensation or fuel residue as well as
the age of the oil also play a role. Because
engine wear increases with mileage, oil con-
sumption will increase again over time until
it may be necessary to replace worn compo-
nents.
— Because all these variables play a role, it is
not possible to define an oil consumption
standard. Therefore, the oil level must be
checked regularly.

Service Facility for assistance.
— If the brake fluid is old, bubbles may form in
the brake system during heavy braking. This
could impair braking performance and driv-
ing safety, which increases the risk of an ac-
cident.
— The brake fluid in your vehicle must meet
the standard VW 501 14 and is available at
an authorized Audi dealer or authorized Au-
di Service Facility. If this brake fluid is not
available, another high-grade brake fluid of
equivalent quality may be used, and it must
meet the U.S. Federal Motor Vehicle Stand-
ard (FMVSS) 116 DOT 4, Class 6.

@) Note
— If the brake fluid level is above the MAX
marking, brake fluid may leak out over the
edge of the reservoir and result in damage
to the vehicle.
— Do not allow any brake fluid to come into
contact with the vehicle paint, because it
will corrode the paint.

Wheels

Tire wear
Check the tires regularly for wear.
—Inflation pressure that is too low
or high can increase tire wear
considerably.
—Driving quickly through curves,
rapid acceleration, and heavy
braking increase tire wear.
—Have an authorized Audi dealer
or authorized Audi Service Facili-
ty check the wheel alignment if
there is unusual wear.
—Have the wheels rebalanced if an
imbalance is causing noticeable
vibration in the steering wheel.
If you do not, the tires and other
vehicle components could wear
more quickly.
Treadwear indicator
Original equipment tires contain
treadwear indicators in the tread
pattern, which are bars that are
1/16 in (1.6 mm) high and are
spaced evenly around the tire per-
pendicular to the running direc-
tion > fig. 192. The letters “TWI”
or triangles on the tire sidewall
indicate the location of the tread-
wear indicators.

D Obey any applicable regulations in the
country where the vehicle is being oper-
ated.
The tires have reached the mini-
mum tread depth ) when they
have worn down to the treadwear
indicators. Replace the tires with
new ones > A.
Hidden damage
Damage to tires and rims can of-
ten occur in locations that are hid-
den. Unusual vibrations in the ve-
hicle or pulling to one side may
indicate that there is tire damage.
Reduce your speed immediately.
Check the tires for damage. If no
damage is visible from the out-
side, drive slowly and carefully to
the nearest authorized Audi deal-
er or authorized Audi Service Fa-
cility to have the vehicle inspect-
ed.

AN WARNING
Tread that has worn too low or
uneven tread depths on the
