Vehicle functions
On-board computer
Depending on the vehicle equipment, you may be
able to access the following information in this
order on the on-board computer > page 70,
fig. 3@:
—Time and date > page 189
— Average consumption
— Short-term memory overview
— Long-term memory overview
— Energy consumers > page 15
— Driver assistance
The short-term memory collects driving informa-
tion from the time the ignition is switched on un-
til it is switched off. If you continue driving within
two hours after switching the ignition off, the
new values are included when calculating the cur-
rent trip information.
Unlike the short-term memory, the long-term
memory is not erased automatically. You can se-
lect the time period for evaluating trip informa-
tion yourself.
Energy consumers*
The Energy consumers view lists other equip-
ment that is currently affecting fuel consump-
tion. The display shows up to three equipment
items. The equipment using the most power is
listed first. If more than three items using power
are switched on, the equipment that is currently
using the most power is displayed. A chart also
shows you the current total of all other consum-
ers.
Fuel consumption
The current fuel consumption can be shown us-
ing a bar graph. The average consumption stored
in the short-term memory is also displayed. If the
bar is green, your vehicle is saving fuel (for exam-
ple, using recuperation).
Engine oil temperature display and boost
indicator
Applies to: vehicles with engine oil temperature display/boost
indicator
The
engine oil temperature display and boost in-
dicator are only shown in the enhanced view or in
the sport view > page 73.
Engine oil temperature indicator
The engine has reached its operating tempera-
ture when the engine oil temperature is between
176 °F (80 °C) and 248 °F (120 °C) under normal
driving conditions. The engine oil temperature
may be higher if there is heavy engine load and
high temperatures outside. This is not a cause for
concern as long as the B or 2 indicator lights
do not turn on.
Boost indicator
The current engine load (meaning the current
boost pressure) is indicated by a bar.
Siam emcees
Applies to: vehicles with shift light indicator
The
shift light indicator informs the driver when
the RPM limit is reached.
Accessing the shift light indicator
Requirement: tiptronic mode must be activated
=> page 85.
> Select the sport view > page 13. The shift light
indicator is displayed with green, yellow and
red ranges in the upper areas of the tachome-
ter.
The shift light indicator will blink red when ap-
proaching the engine speed limit. Shift to the
next highest gear at the right time.
Syme ENT
Applies to: vehicles with Sport displays
Depending on the vehicle equipment, the sport
displays may include the G-meter, the engine da-
ta and the tire pressure monitoring system. You
can access the sport displays in the central area
or in the additional display in the driver informa-
tion system. >

Driving

Driving
General information
Breaking in
A new vehicle must be broken in within the first
1,000 miles (1,500 km) so that all moving parts
work smoothly together, which helps to increase
the service life of the engine and other drive com-
ponents.
Do not drive higher than two-thirds of the maxi-
mum permitted engine RPM during the first 600
miles (1,000 km) and do not use full accelera-
tion. The engine can be increased RPM gradually
during the next 300 miles (S00 km).
Trailer mode
® Note
Your Audi is not designed for towing a trailer.
Damage caused by towing a trailer is not cov-
ered by the warranty.
Reducing the risk of vehicle damage
@) Note
When driving on poor roads, over curbs, and
on steep ramps, make sure that components
that hang below the vehicle, such as the spoil-
er and exhaust system, are not struck because
they could be damaged. This especially ap-
plies
to vehicles with low ground clearance
and vehicles that are heavily loaded.
Driving through water
If you must drive through water, follow these in-
structions:
— Check the stability of the ground, the current,
and the water depth. If the ground is unstable,
there is a strong current, or there are waves,
the water must only reach up to the lower edge
of the body at the most.
— Deactivate the Start/Stop system*.
— Drive carefully and no faster than at walking
speeds to prevent the front of the vehicle from
creating waves, because they could splash
above the lower edge of the body. Oncoming
vehicles could also create waves.
— Do not stop the vehicle while in the water.
— Drive in reverse.
— Do not turn the engine off.

ZA WARNING
After driving through water, press the brake
pedal carefully to dry the brakes so that the
full braking effect will be restored.
@) Note
Vehicle components such as the motor, drive
system, suspension, or electrical system can
be severely damaged by driving through wa-
ter
Gi) Tips
If possible, avoid driving through salt water
because it increases the risk of corrosion. Use
fresh water to clean any vehicle components
that come into contact with salt water.
Efficient and environmentally-friendly
driving
The amount of fuel consumption, the environ-
mental impact, and the wear to the engine,
brakes, and tires depends mostly on your driving
style. Note the following information for efficient
and environmentally-conscious driving:

— Turn off electrical equipment that is not need-
ed, for example seat heating*.
— Anticipate upcoming traffic situations while
driving to avoid unnecessary acceleration and
braking.
— Avoid driving at high speeds.
— Avoid adding extra weight to the vehicle if pos-
sible, for example by not leaving roof racks or
bike racks installed when they are not needed.
— Make sure the tire pressure is correct.
— Have maintenance performed regularly on the
vehicle.
— Do not let the engine run while the vehicle
parked.

pressed. To reduce the risk of an accident,
do not inadvertently press the accelerator
pedal and always shift into “P” when the ve-
hicle is stopped.
— If the power supply fails, you cannot set the
parking brake once it is released, or release
it if it is set. In this case, park the vehicle on
level ground and secure it by engaging the
"P” gear. Contact an authorized Audi dealer
or authorized Audi Service Facility for assis-
tance.

ZA WARNING
— If you do not begin driving immediately after
releasing the brake pedal, your vehicle may
begin to roll backward. Press the brake ped-
al or set the parking brake immediately.
— The hill hold assist cannot hold the vehicle
on inclines in every scenario (for example,

on slippery or icy ground).

Sporty driving
Applies to: RS models
When driving in a sporty style, the wear on all ve-
hicle components is greatly increased, especially
on the engine, transmission, tires, brakes, and
suspension. This can result in increased wear. Al-
so
note the following points:
— Make sure the vehicle is in good condition.
Make sure to check the brake pads, tire tread,
and tire pressure (when tires are warm).
— Beforehand, warm up the engine by driving no
higher than two-thirds of the maximum permit-
ted engine RPM. The engine oil must be
brought to a minimum temperature of 158 °F
(60 °C).
— Before stopping the vehicle, allow the engine
and brakes to cool back down to a regular oper-
ating temperature by driving normally.
If necessary, use the following functions:
— Dynamic Audi drive select mode* > page 96
— Launch Control > page 86
— Limit ESC > page 105
@) Tips
Wear caused by load does not constitute a ve-
hicle fault as defined by the terms of the war-
ranty.
Automatic transmission
Introduction
Your vehicle is equipped with an electronically-
controlled DSG transmission called S tronic. Two
independent clutches transfer the power be-
tween the engine and transmission. It allows the
vehicle to accelerate without a noticeable inter-
ruption in traction.
The transmission shifts up or down automatically
depending on which drive program is selected.
When a moderate driving style is used, the
transmission selects the most economical driving
mode. The transmission upshifts at a lower RPM
and downshifts at a higher RPM to improve fuel
efficiency.
The transmission switches to a sporty mode after
a kick-down or when the driver uses a sporty driv-
ing style characterized by quick accelerator pedal
movements, heavy acceleration, frequent
changes in speed, and traveling at the maximum
speed.
If desired, the driver can also select the gears
manually (tiptronic mode) > page 85.

— Set the parking brake.
— Select the “P” (Park) selector lever position.
— Allow the engine to cool.
— Keep children away from the motor com-
partment.
— Never spill fluids on a hot engine. These flu-
ids (such as the freeze protection contained
in the coolant) can catch fire.
— Avoid short circuits in the electrical system.
— Never reach into the radiator fan. The fan is
temperature-controlled and can turn on
suddenly, even when the ignition is switched
off.
— Never open the hood when there is steam or
coolant escaping from the motor compart-
ment, because there is a risk that you could
be burned. Wait until no steam or coolant is
escaping.
—The cap on the coolant expansion tank must
never be opened when the coolant is hot.
The cooling system is under pressure. There
is a risk of burns
— To protect your face, hands, and arms from
hot steam or coolant, cover the cap with a
thick cloth when opening.
— Do not remove the engine cover under any
circumstances. This increases the risk of
burns.
— Due to the risk of electric shock, never touch
the ignition cable or other components in
the electronic high-voltage ignition system
when the engine is running or is starting.
— If a gear is engaged while the vehicle is sta-
tionary and the engine is running, do not
press the accelerator pedal inadvertently.
Pressing the accelerator pedal will cause the
vehicle to move, and this could result in an
accident.
— If inspections or repairs must be performed
while the engine is running, moving compo-
nents (such as the ribbed belt, generator,
and radiator fan) pose an additional risk.
— Set the parking brake first and select the
“P” (Park) selector lever position.
— Always make sure that no parts of the
body, jewelry, ties, loose clothing, and
long hair can be caught in moving engine
components. Before any work, always re-
move any jewelry and/or ties, tie back long
hair, and make sure all clothing fits close
to the body to reduce the risk of anything
becoming caught in engine components.
— Pay attention to the following warnings list-
ed when work on the fuel system or on the
electrical equipment is required.
— Do not smoke.
— Never work near open flames.
— Always have a working fire extinguisher
nearby.

Glossary of tire and loading
terminology
Accessory weight
means the combined weight (in
excess of those standard items
which may be replaced) of auto-
matic transmission, power steer-
ing, power brakes, power win-
dows, power Seats, radio, and
heater, to the extent that these
items are available as factory-in-
stalled equipment (whether in-
stalled or not).
Aspect ratio
means the ratio of the height to
the width of the tire in percent.
Numbers of 55 or lower indicate a
low sidewall for improved steer-
ing response and better overall
handling on dry pavement.
Bead
means the part of the tire that is
made of steel wires, wrapped or
reinforced by ply cords and that is
shaped to fit the rim.
Bead separation
means a breakdown of the bond
between components in the bead.
Cord
means the strands forming the
plies in the tire.
Cold tire inflation pressure
means the tire pressure recom-
mended by the vehicle manufac-
turer for a tire of a designated
size that has not been driven for
more than a couple of miles (kilo-
meters) at low speeds in the three
hour period before the tire pres-
sure is measured or adjusted.
Curb weight
means the weight of a motor ve-
hicle with standard equipment in-
cluding the maximum capacity of
fuel, oil, and coolant, air condi-
tioning and additional weight of
optional equipment.
Extra load tire
means a tire designed to operate
at higher loads and at higher in-
flation pressures than the corre-
sponding standard tire. Extra load
tires may be identified as “XL”,
“xl”, “EXTRA LOAD”, or “RF” on
the sidewall.

Use the tire pressure specified for
a normal vehicle load when the
vehicle is partially loaded > table
on page 226. If driving the vehicle
when fully loaded, you must in-
crease the tire pressure to the
maximum specified pressure > A.
Checking and correcting tire
pressure
>Check the tire pressure at least
once per month and also check it
before every long drive.
> Always check the tire pressure
when the tires are cold. Do not
reduce the pressure if it increas-
es when the tires are warm.
>Refer to the sticker > fig. 178
for the correct tire pressure.
>Correct the tire pressure if nec-
esSary.
> Store the new tire pressure in
the Infotainment system
=> page 232 or > page 235.
> Check the pressure in the emer-
gency
tire*/spare tire*. Always
maintain the maximum temper-
ature that is specified for the
tire.


Z\ WARNING
Always adapt the tire pressure
to your driving style and the ve-
hicle load.


—Overloading can lead to loss of
vehicle control and increase
the risk of an accident. Read
and follow the important safe-
ty precautions in > page 227.
—The tire must flex more if the
tire pressure is too low or if
the vehicle speed or load are
too high. This heats the tire up
too much. This increases the
risk of an accident because it
can cause the tire to burst and
result in loss of vehicle con-
trol.
—Incorrect tire pressure increas-
es tire wear and has a negative
effect on driving and braking
behavior, which increases the
risk of an accident.

@) Note
Replace lost valve caps to re-
duce the risk of damage to the
tire valves.
© For the sake of the envi-
ronment
Tire pressure that is too low in-
creases fuel consumption.

Wheel bolts and rims
Wheel bolts
Wheel bolts must be clean and loosen/tighten
easily.
Rims
Rims with a bolted rim ring* or with bolted wheel
covers* consist of multiple pieces. These compo-
nents were bolted together using special bolts
and a special procedure. You must not repair or
disassemble them > A\.

ZA\ WARNING
Wheel bolts that are tightened or repaired in-
correctly can become loose and result in loss
of vehicle control, which increases the risk of
an accident. For the correct tightening specifi-
cation, see > page 248, Finishing.
— Always keep the wheel bolts and the threads
in the wheel hub clean and free of grease.
— Only use wheel bolts that fit the rim.
— Always have damaged rims repaired by an
authorized Audi dealer or authorized Audi
Service Facility. Never repair or disassemble
rims yourself, because this increases the risk
of an accident.
Winter tires significantly improve the vehicle's
handling when driving in winter conditions. Be-
cause of their construction (width, compound,

tread pattern), summer tires provide less traction
on ice and snow.
> Use winter tires on all four wheels.
> Only use winter tires that are approved for your
vehicle.
> Please note that the maximum permitted
speed may be lower with winter tires > /A\ in
General information on page 214. An author-
ized Audi dealer or authorized Audi Service Fa-
cility can inform you about the maximum per-
mitted speed for your tires.
> Check the tire pressure after installing wheels
=> page 224.
The effectiveness of winter tires is reduced great-
ly when the tread is worn down to a depth of
0.16 in (4 mm). The characteristics of winter
tires also decrease greatly as the tire ages, re-
gardless of the remaining tread.
@ For the sake of the environment
Reinstall summer tires at the appropriate
time, because they provide better handling
when roads are free of snow and ice. Summer
tires cause less road noise, tire wear, and fuel
consumption.
@® Tips
You can also use all season tires instead of
winter tires. Please note that in some coun-
tries where winter tires are required, only
winter tires with the 44 symbol may be per-
mitted.
Snow chains improve both driving and braking in
winter road conditions.
> Only install snow chains on the front wheels.
> Check and correct the seating of the snow
chains after driving a few feet, if necessary. Fol-
low the instructions from the manufacturer.
> Note the maximum speed of 30 mph
(50 km/h). Observe the local regulations.
Use of snow chains is only permitted with certain
rim/tire combinations due to technical reasons.

generation of heat and its ability to dissipate
heat when tested under controlled conditions on
a specified indoor laboratory test wheel.
Sustained high temperature can cause the mate-
rial of the tire to degenerate and reduce tire life,
and excessive temperature can lead to sudden
tire failure > A.
The grade C corresponds to a level of perform-
ance which all passenger car tires must meet un-
der the Federal Motor Vehicle Safety Standard
No. 109. Grades B and A represent higher levels
of performance on the laboratory test wheel than
the minimum required by law.

ZA\ WARNING
The traction grade assigned to this tire is
based on straight-ahead braking traction
tests, and does not include acceleration, cor-
nering, hydroplaning or peak traction charac-
teristics.

ZA\ WARNING
The temperature grade for this tire is estab-
lished for a tire that is properly inflated and
not overloaded. Excessive speed, underinfla-
tion, or excessive loading, either separately or
in combination, can cause heat buildup and
possible tire failure.

Z\ WARNING
Temperature grades apply to tires that are
properly inflated and not over or underinflat-
ed.

Tire pressure monitoring
system
(1) General notes
Each tire, including the spare (if provided),
should be checked monthly when cold and inflat-
ed to the inflation pressure recommended by the
vehicle manufacturer on the vehicle placard or
tire
inflation pressure label. (If your vehicle has
tires of a different size than the size indicated on
the vehicle placard or tire inflation pressure la-
bel, you should determine the proper tire infla-
tion pressure for those tires).
As an added safety feature, your vehicle has been
equipped with a tire pressure monitoring system
(TPMS) that illuminates a low tire pressure tell-
tale when one or more of your tires is significant-
ly under-inflated. Accordingly, when the low tire
pressure telltale illuminates, you should stop and
check your tires as soon as possible, and inflate
them to the proper pressure. Driving on a signifi-
cantly under-inflated tire causes the tire to over-
heat and can lead to tire failure. Under-inflation
also reduces fuel efficiency and tire tread life,
and may affect the vehicle's handling and stop-
ping ability.
Please note that the TPMS is not a substitute for
proper tire maintenance, and it is the driver's re-
sponsibility to maintain correct tire pressure,
even if under-inflation has not reached the level
to trigger illumination of the TPMS low tire pres-
sure telltale.
Your vehicle has also been equipped with a TPMS
malfunction indicator to indicate when the sys-
tem is not operating properly. The TPMS mal-
function indicator is combined with the low tire
pressure telltale. When the system detects a
malfunction, the telltale will flash for approxi-
mately one minute and then remain continuously
illuminated. This sequence will continue upon
subsequent vehicle start-ups as long as the mal-
function exists.
When the malfunction indicator is illuminated,
the system may not be able to detect or signal
low tire pressure as intended. TPMS malfunctions
may occur for a variety of reasons, including the
installation of replacement or alternate tires or
wheels on the vehicle that prevent the TPMS
from functioning properly. Always check the
TPMS malfunction telltale after replacing one or
more tires or wheels on your vehicle to ensure
that the replacement or alternate tires and
wheels allow the TPMS to continue to function
properly.
