Cockpit overview
On-Board Diagnostics
Fig. 19 Location of Data Link Connector (DLC)
On-Board Diagnostics monitors the components
of your emission control system. Each monitored
component in your engine system has been as­
signed a code . In case of a malfunction, the com­
ponent will be identified and the fault stored as a
code in the control module memory.
The MIL light may also illuminate if there is a
leak in the on-board fuel vapor recovery system.
If the light illuminates after a refueling, stop the
vehicle and make sure the fuel filler cap is prop­
erly closed
¢ page 269.
In order to make an accurate diagnosis, the stor­
ed data can only be displayed using special diag­
nostic equipment (generic scan tool for OBD).
In order to connect the special diagnostic equip­ ment, push the plug into the Data Link Connector
(DLC). The DLC is located to the right of the hood
release
¢ fig. 19.
Your authorized Audi dealer or a qualified service
station can interpret the code and perform the
necessary repair.
A WARNING
Do not use the diagnostic connector for per­
sonal use. Incorrect usage can cause malfunc­
tions, which can increase the risk of a colli­
sion!
Electronic speed limiter
-
Your vehicle may be factory equipped with tires
that are rated for a maximum speed of 130 mph (210 km/h). This is less than the maximum speed
of your vehicle . To reduce the risk of sudden tire
26
failure and loss of control if the vehicle is operat­
ed at excessive speeds, your vehicle also has an
electronic speed limiter. The electronic speed
limiter prevents your vehicle from going faster
than the tire speed rating. For more information
¢ page 290.
If the engine control unit receives faulty vehicle
road speed signals, the Malfunction Indicator
Lamp (MIL)
¢'4 will illuminate. If this occurs,
contact the nearest authorized Audi dealer for
ass istance.
58
Your vehicle's top speed is electronically limited
to 155 mph (250 km/h).
If the engine control unit receives faulty vehicle
roadspeed signals, the Malfunction Indicator
Lamp (MIL)
¢'4 will illuminate. If this occurs,
contact the nearest authorized Audi dealer for
assistance.
A WARNING
Always observe the posted speed limits and
adjust your speed to suit prevailing road, traf­
fic and weather conditions. Never drive your vehicle faster than the maximum speed rating
of the ti res installed.

General information
Breaking in
A new vehicle must be broken in, and the break­
in distance should be 1,000 mi les ( 1,500 km). Do
not drive at speeds that w ill exceed
2/3 of the
maximum permitted engine speed
(RPM) for the
first 600 miles (1,000 km) , and avoid full accel­
eration during this period . You may gradually
start increasing the
RPM and the speed between
600 miles (1,000 km) and 1,000 miles (1,500
km).
During the first hours of use, the engine has a
higher internal friction than later on when all
moving parts have settled into place with each
other.
How the vehicle is driven during the first 1,000
miles (1,500 km) also affects the engine quality.
Drive at moderate engine speeds after the initial
break-in per iod, part icularly when running a cold
engine . This will reduce engine wear and improve
the mileage .
Do not drive at too low of an engine speed (rpm).
Shift down if the engine stops running "smooth­
ly" . Extremely high eng ine speeds are automati ­
cally reduced .
New tires
If your vehicle is running on new tires, drive pa r­
ticularly careful for the first 350 miles (500 kilo­
meters) after fitting .
.&_ WARNING
-
New tires tend to be slippery and must also
be "broken-in". Be sure to remember this dur­
ing the first 350 miles (500 kilometers).
Brake gently . Avo id following closely behind
other vehicles or other situations that might
require sudden, hard brak ing.
Avoid damaging the vehicle
When you are driving on poor roads, or over
curbs, steep ramps, etc., make certain that low-
Driving
lying parts such as spoilers and exhaust system
parts do not bottom out and get damaged .
T h is is espec ially true for veh icles with low-s lung
chass is (sports chassis)* and fully loaded
vehicles .
Driving through water on roads
Note the following to reduce the risk of vehicle
damage when driving through water, for example
on flooded roads:
- The water must not be any higher than the bot­
tom of the vehicle body.
- Do not drive faste r than walk ing speed.
.&_ WARNING
=
After driving through water or m ud, the effec-
tiveness of the brakes may be reduced due to moisture on the brake rotors and brake pads.
A few careful brake applications should dry
off the brakes .
(D Note
-Vehicle components such as the engine,
transmission, suspension or electrical sys­
tem can be severely damaged by driving
through water.
- Always switch off the Start/Stop system
when driving through water r::;,page
78.
{i) Tips
- Determine the depth before driving through
water.
- Do not stop the vehicle, drive in reverse or
switch the engine off when driving through
water.
- Keep in mind that oncom ing vehicles may
create waves that raise the water level and
make it too deep for your vehicle to drive
through safely.
- Avoid dr iving through salt water, because
this can cause corrosion .

Driving
Economical and environmentally-friendly
driving
The amount of fue l consumption, the environ ­
mental impact and the wear to the engine,
brak es and tir es d epends mostly on your driving
style. W ith an anticipatory and economic driv ing
style, fuel consumption can be reduced by ap­ proximately 10-15% . The following tips will help
you conserve the environment and your money at the same time .
Anticip atory d riving
A vehicle uses the most fuel when acce lerating.
When you drive with ant ic ipat ion , you do not
need to brake as often and so you accelerate less .
When possible, let your ve hicle coast w ith a
g ear
e ngag ed ,
for example , when you notice that the
next traffic light is red. This produ ces a n eng ine
b raking effect, which helps to protect the brakes
and tires and reduces the emissions and fuel con­
sumption to zero (f uel shut-off during decelera ­
tion).
Shift effici ently
An effective way to save f uel is to upshift earlie r.
Staying in a gear too long uses fue l unnecessari ­
ly. Press down on the accelerator pedal slowly
and avoid "k ick-down".
Avoid full acceleration
You sho uld rare ly t ravel at the maximum vehicle
speed. High speeds cause a disp roportiona tely
h igh increase in fuel consumption, emissions and
traffic noise . Slower driving saves fuel.
Reduce idling time
The Start-Stop system * helps to reduce the id ling
time automatically . In vehicles witho ut the Start­
S top sys tem* , it is efficient to switch the eng ine
off when stopped at ra ilroad cross ings a nd long
red lights . Stopping t he engine for 30 -40 sec ­
onds already saves more fuel than the amount of
extra fuel needed to restart the eng ine .
It takes a very long time in idle to wa rm the en­
gine up to operating temperature . Wea r and
emissions are especially high in the warm -up
phase. Therefore, yo u should begin driving im-
74
mediate ly after s tarting the engine . Avoid high
RPMs whi le doing this.
Have maintenance performed regularly
By having maintenance pe rformed regu la rly on
you r vehicle, you can help to reduce fuel con ­
s u mption before you even sta rt to drive. The
maintenance condition of your vehicle not on ly
affects traffic safety and long-term value but al ­
so impacts fuel consumption. A poorly main­
ta ined engine can lead to fuel consumption that
i s 10% higher than normal.
Avo id short trip s
The engine and exha ust cleaning system must
reach their optima l operating temperature to ef­
fect ive ly reduce consumpt ion and emissions.
A cold engine uses a d isproportionately high
amount of fue l. The engine reaches operating
temperat ure and cons umption no rmalizes on ly
after approximate ly four kilometers.
Check the tire pre ssure
To save fuel, ma ke sure the tires are always in­
flated to t he corre ct pressure
¢ page 291 . The
fuel consumption can increase by 5% if the pres­
sure is only 0 .5 bar too low. Due to the increased
roll ing resistance, low tire pressures w ill also
lead to greater tire wear and will affect driving
behavior.
D rive with summer tires when possib le because
th is can increase fue l economy by up to 10%.
Eliminate unnecessary we ight
Since eve ry po und of extra weight increases f uel
consump tion, it pays to remove any unnecessa ry
weight .
A roof rac k increases the w ind resis tan ce on the
vehicle and shou ld be removed when it is not
needed . You will save approximately 12% o f you r
fuel when at speeds from 62-75 mph (100-120 km/h) .
Save energy
The eng ine d rives the genera tor , which gene rates
e lectric ity; the fuel consumpt ion also increases
with t he demand for e lec tricity . T he refore, switch ..,_

Trailer mode
Trailer load distribution
Be s ure the load in the trailer is held securely in
p lace to prevent it from shifting forward, back­
ward or sideways .
Never allow a passenger to ride in a trailer¢.&.
in Driving instructions on page 91.
Engine cooling system
Towing a trailer makes the eng ine work harder . It
is important that the cooling system's perform­
ance is up to the additional load. Make sure that
the cooling system has eno ugh fluid.
Tire pressure
When tow ing a tra iler, inflate the tires of your
veh icle to the tire pressure listed under "Full
load " on the label ¢
page 293 . Inflate trailer
tires to trailer and tir e manufacturers' specifica­
tions.
Lights
Check to make sure both vehicle and trailer lights
are working properly .
Safety chains
Be sure trailer safety chains are properly connect­
ed from the trailer to the hitch on the vehicle. Leave enough slack in the chains to permit turn­
ing corners . When you install safety cha ins, make
sure they w ill not drag on the road when you are
driving.
The chains should cross under the trailer tongue to prevent it from dropping in case of separation
from the hitch.
Adjusting the Audi drive select
Make sure the vehicle is on a level surface before
hitching up the trailer and before adjust ing the
tongue weight. The vehicle must be in
auto or
comfort driving mode and not raised
o:,;, page 110, o:,;, 0 .
Make sure that the vehicle is lowered. In Info­
tainment, select:
ICARI function button> Lower
control button.
90
If you must drive under poor road conditions, you
can raise the vehicle
after coupling the trailer or
after adjust ing the tongue we ight ¢ page 112.
([) Note
-Changes in temperature or load can affect
the height of the vehicle.
- Always select auto or comfort mode. Other­
wise, the tongue load specified for your ve­
hicle will no longer be app licab le .
Driving instructions
Driving with a trailer always requires extra care
and consideration.
Weight distribution
Towing a loaded trailer with an empty car results
i n a high ly unstable distribution of we ight . If this
cannot be avoided, drive at very low speeds only
to avoid t he risk of losing steering contro l.
A "balanced " rig is easier to operate and control.
This means that the tow vehicle should be loaded
to the extent possible and permissib le, wh ile
keeping the trailer as light as possible under the
circumstances. Whenever possible, transfer
some cargo to the luggage compartment of the
tow veh icle while observing tongue load require­
ments and vehicle loading considerations.
Speed
The higher the speed, the more difficult it be­
comes for the driver to control the rig . Do not
drive at the maximum permissible speed. Reduce
your speed even more if load, weather or wind cond it ions are unfavorable - particularly when
go ing downh ill.
Reduce vehicle speed
immediately if the trailer
shows the slightest sign of sway ing.
Do not try
to stop the swaying by accelerating.
Observe speed limits. In some areas, speeds for
vehicles towing trailers are lower than for regular
vehicles.
Always apply brakes early. When driving down­
hill, shift into a lower gear to use the engine
braking effect to slow the vehicle. Use of the
brakes alone can cause them to overheat and fail. ..,.

Ass is t
Assist
Speed warning system
The speed warning system helps you to stay un­
der a specified maximum speed.
The speed warning system warns you if you are
exceeding the maximum speed that you have set.
A warning tone will sound as soon as your speed
exceeds the stored value slightly.
The . (USA models)
I. (Canada models) indi ­
cator light and a message appear in the instru­
ment cluster display at the same time. The./
• indicator light and the message turn off if the
speed falls back below the stored maximum
speed.
Setting a threshold is recommended if you would
like to be reminded when you reach a certain
maximum speed. Situations where you may want
to do so include driving in a country with a ge ner ­
al speed limit or if the re is a specified max imum
speed for winter tires.
Setting the warning threshold
The warning threshold is set in the Infotainment
system .

Regardless of the speed wa rning system, you
should always monitor yo ur speed using the
speedometer and make sure you are following
the legal speed limit.

_& WARNING
-Always pay atten tion to the traffic around
you when the cruise contro l system is in op­
erat ion. You are always respons ible for your
speed and the distance between your ve hi­
cle and other vehicles.
- For safety reasons, cruise control should not
be used in the city, in stop-and-go traff ic, on
w inding roads and when road conditions are
poor (such as ice, fog, gravel, heavy rain and
hydroplaning), because this increases the
r is k of an a ccident.
- Switch t he cruise control off temporarily
when dr iving in turning lanes, highway exits
or in construction zones.

0 co .... N ,..... N .... 0 0 :c ' depends on the driving mode selected, steering
movements, the driver's braking and accelera­
tion, and as the road surface, vehicle speed and load. A sporty setting is generally used in vehicles
with adaptive air suspension sport*.
The vehicle ground clearance depends on the
mode selected and the speed. When you are in
the auto or dynamic mode, the highway setting is
activated when you drive above 75 mph (120 km/
h) for more than 30 seconds. The ground clear­
ance is increased automatically if the speed
drops below 44 mph (70 km/h) for more than 120 seconds .
Steering
The power steering adapts. Indirect steering that
moves easily as in comfort mode is especially
suited to long drives on a highway. The dynamic
mode provides sporty, direct steering .
Applies to: vehicles with dynamic steering
The steering ratio changes based on vehicle
speed in order to maintain optimum steering ef ­
fort for the driver at all times . This sets the steer­
ing to be less sensitive at higher speeds in order
to provide improved vehicle control. At reduced
speeds, steering is more direct in order to keep
the steering effort as minimal as possible when
the driver is maneuvering the vehicle. At low and
average speeds, dynamic steering* additionally
provides more responsive steering performance.
Sport differential*
As a component of the all wheel drive system
(quattro)
~ page 130, the sport differential dis­
tributes the driving power to the rear axle de­
pending on the situation. The distribution of
power varies from balanced (comfort) to sporty
(dynamic) depending on the selected mode. The
goal is a high level of agility and ability to accel ­
erate on curves. The vehicle is very responsive to
steering .
Cornering light*
The cornering light adapts the high beams to the
direction of the curve depending on the speed.
The pivoting action and the lighting also adapt to
the mode .
Assist
Adaptive cruise control*
The behavior when accelerating can be adjusted
from comfortable 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 engine sound adapts to the current mode
and can be subtle to sporty.
(D Note
- Make sure there is enough clearance above
and below the vehicle when parking. The
height of the vehicle can change once it is
parked due to temperature fluctuations,
changes to the load conditions and changes
to the driving modes, which can affect clear­
ance.
- When transporting the vehicle on a car car­
rier, train, ship or by other means, only tie
the vehicle down at the running surface of
the tires, which is the outer circumference.
Securing the vehicle at the axle compo­
nents, suspension struts or towing eyes is
not permitted because the pressure in the
air suspension struts can change during
transport. The vehicle may not be secured
sufficiently if this happens.
@ Tips
- In some models, the maximum vehicle
speed can only be reached in the auto and
dynamic modes.
- The S selector lever position automatically
engages if the dynamic mode is selected.
- In vehicles that have dynamic steering*, op­
erating noise is heard when starting or stop­
ping the engine. This does not indicate a
problem.

Intelligent Technology
The stee ring wheel will be easy to move after
starting the engine . Re-initialization might be
necessary if the steering whee l was moved hard
t o the lef t and right wh ile the vehicle was not
mov ing. The display turns off if the initialization
was successful.
(D Tips
- If the. or
1;:r- ij ind icator light only stays on
for a short time, you may continue driving.
- The dynamic steering stability systems
c> page 126 are not available in the event of
a system ma lfunction.
- For additional informat ion on dynamic
steering, refer to
c> page 110.
All wheel drive (quattro)
In all wheel drive, all four wheels are powered .
General information
In a ll wheel drive, the driving power is divided be­
tween a ll four wheels . T his happens automatical ­
ly depending on your driving behavior as well as
t he current road cond itions. Also see
c> page 126, Electronic Stabilization Control
(ESC) .
With the sport differential*, power distri­
bution to the rear whee ls is variable and can be
ad ju sted using the dr ive select
c> page 110.
The all wheel drive concept is designed for h igh
eng ine power. Your ve hicle is exceptionally pow­
erful and has excellent driving characterist ics
both under norma l dr iv ing condit ions and on
snow a nd ice. Always read and fo llow safety pre­
cautions
c> .&. .
Winter tires
By us ing all w heel d rive , yo ur vehicle has good
forward mot ion w ith standa rd t ires in winter con­
d itions . However, in winter we recommend us ing
w in ter o r all season t ires o n all fo ur wheels, be ­
cause this will improve the b raking effect .
Snow chains
If there are snow chai n laws, snow chains must
a lso be used on vehicles with all w heel d rive
c> page 298, Snow chains .
130 Replacing tires
Fo
r vehicles wi th a ll wheel d rive, o nly wheels with
the same ro ll ing circ umfe rence sho uld be used .
Avo id using tires with different tread depths
c> page 290, New tires or wheels .
Offroad vehicle?
You r A udi is not an off road vehicle -there is not
enough ground clearance. For th is reason, avoid
difficult terrain .
A WARNING
- Also, in ve hicles with all wheel drive, adapt
your driving sty le to the current road and
traffic conditions. Do not let the increased
safety provided tempt you into taking r isks,
because this increases the risk of an acc i­
dent.
- The braking ab ility of your vehicle is limited
to the traction of the wheels . In this way, it
is not different from a two wheel d rive vehi­
cle. Do not be tempted to accelerate to a high speed when the road is s lippery, be ­
c a use th is i ncreases the r is k of an accident.
- Note that on wet st reets, the front wheels
c a n " hydroplane " if driv ing at speed s tha t
are too high. Unlike front wheel drive
vehicles, t he engine does not rev higher sud ­
de nly when the vehicle begins hydroplan ing.
For this reason, adapt yo ur speed to the
road conditions to reduce the risk of an acci­
dent.
Energy management
The starting ability is optimized
The energy management system manages the
electrical energy distribution and optimizes the
availability of electrical energy for starting the
engine.
When a vehicle with a conventiona l energy sys­
tem is no t drive n for a long t ime, the veh icle bat­
te ry is drained by equ ipment (fo r example, the
i mmob ilizer). In certa in circ umstances, there
could may not be enough energy to start the en ­
gine.
