Opening and closing

Opening and closing
Central locking
You can lock and unlock the vehicle centrally. You
have the following options:
— Remote control key > page 21
— Sensors in the door handles* > page 22
— Lock cylinder on the driver's door > page 24,
or
— Interior central locking switch > page 23
Automatic locking function (Auto Lock)
The Auto Lock function locks all doors and the
luggage compartment lid once the speed has ex-
ceeded approximately 9 mph (15 km/h).
The vehicle can be unlocked if the opening func-
tion in the central locking system switch is used
or one of the door handles is pulled. The Auto
Lock function can be switched on and off in the
Infotainment system > page 23.
In the event of a crash with airbag deployment,
the doors will also automatically unlock to allow
access to the vehicle.
Selective door unlocking
The doors and luggage compartment lid will lock
when they close. You can set in the Infotainment
system whether only the driver's door or the en-
tire vehicle should be unlocked when unlocking
=> page 23.
Turn signals
The turn signals flash twice when you unlock the
vehicle and flash once when you lock the vehicle.
If they do not flash when locking, check if all
doors and lids are closed.
Unintentionally locking yourself out
Only lock your vehicle when all of the doors and
the luggage compartment lid are closed and the
remote control key is not in the vehicle. This re-
duces the risk of locking yourself out accidental-
ly.
18
The following conditions prevent you from lock-
ing your remote control key in the vehicle:
— If the driver's door is open, the vehicle cannot
be locked by pressing the & button on the re-
mote control key or by touching the locking
sensor* on a door.
— If the most recently used convenience key* is
inside the luggage compartment, the luggage
compartment lid will automatically open again
after closing it.
— If the convenience key* that was last used is de-
tected inside the vehicle, then the vehicle can-
not be locked from the outside > @.
@) Note
Applies to: vehicles with convenience key
The following applies when locking the vehi-
cle:
— If the vehicle key that was last used is de-
tected inside the passenger compartment,
then the vehicle cannot be locked from the
outside using the sensor. Take the vehicle
key with you and lock the vehicle again. Oth-
erwise, the vehicle will not be protected
against unauthorized access.
— If you try to lock the vehicle using the but-
ton on the vehicle key while the front pas-
senger's door is open, and you accidentally
place the vehicle key inside the passenger
compartment and close the door, the vehi-
cle will lock at first. But if the keyless sys-
tem detects a vehicle key inside the vehicle
after it locks, then the vehicle will unlock
again. The turn signals will flash several
times to indicate this. If you do not open the
vehicle to remove the vehicle key within a
brief period, then the vehicle will lock auto-
matically. This prevents the vehicle from be-
ing left unlocked for long periods of time.
The vehicle key will then be locked inside
the vehicle.
— If the luggage compartment lid closes and
the system detects that the last conven-
ience key* that was used is inside the lug-
gage compartment, then the luggage com-
partment lid will open again. The turn sig-
nals will flash several times to indicate this.
The doors will lock. Always take the vehicle >

Lights and Vision

if the mirrors fold in automatically when you lock
the vehicle > page 23.
Front passenger's exterior mirror tilt
function*
Requirement: the knob must be in the position
for the front passenger’s exterior mirror.
The mirror surfaces tilt slightly when reverse
gear is selected to provide a better view, for ex-
ample of the edge of the curb.
You can adjust the mirror surface by turning the
knob in the desired direction. When you move
out of reverse and into another gear, the new
mirror position is stored and assigned to the key
you are using.
The mirror goes back into its original position
once you drive forward faster than 9 mph
(15 km/h) or turn the ignition off.

Z\ WARNING
Curved mirror surfaces (convex) enlarge the
field of vision. However, they make objects in
the mirror appear smaller and farther away.
When using these mirrors to estimate your
distance to vehicles behind you when chang-
ing lanes, you could estimate incorrectly,
which increases the risk of an accident.

@) Note
If the mirror housing was moved by force (for
example, by running into an object when ma-
neuvering the vehicle), the mirror must be
folded all the way in using the power folding
function. The mirror housing must not be
moved back into place by hand because this
could impair the function of the mirror mech-
anism.
@ Tips
If the power adjusting function malfunctions,
the glass in both mirrors can be adjusted by
pressing on the edge of it by hand.

fluid can irritate skin, eyes and airways.
— Repeated or long-term exposure to electro-
lyte fluid can lead to irritation of the air-
ways, especially in people with asthma or
other respiratory conditions. Take deep
breaths immediately after leaving the vehi-
cle or, if this is not possible, open all of the
doors and windows as wide as possible.
— If electrolyte fluid comes into contact with
the eyes, flush them thoroughly with plenty
of clean water for at least 15 minutes and
then seek medical attention.
— If electrolyte fluid comes into contact with
the skin, flush the affected area with clean
water for at least 15 minutes, and then
clean with soap and water and seek medical
attention. Clean affected clothing and shoes
thoroughly before wearing again.
— If the fluid was swallowed and the person is
conscious, flush the mouth with water for at
least 15 minutes. Do not induce vomiting
unless this is recommended by medical pro-
fessionals. Seek medical attention immedi-
ately.
() Note
If the glass on an automatic dimming mirror
breaks, electrolyte can leak out. This liquid
damages plastic surfaces. Clean this liquid as
quickly as possible, for example with a wet
sponge.

Lights and Vision


— The windshield must not be treated with
water-repelling windshield coating agents.
Under unfavorable conditions, such as wet-
ness, darkness, and when the sun is low,
these coatings can cause increased glare,
which increases the risk of an accident. They
can also cause wiper blade chatter.
— Properly functioning windshield wiper
blades are required for a clear view and safe
driving > page 42, Replacing windshield
wiper blades.

> Place the windshield wiper arms in the service
position > page 42.
> Fold the windshield wiper arms away from the
windshield.

ZX WARNING
Dirty windshield wiper blades can impair vi-
sion, which increases the risk of an accident.
Replacing windshield wiper blades


@) Note
— If there is frost, make sure the windshield
wiper blades are not frozen to the wind-
shield. Switching on the windshield wipers
when the blades are frozen to the wind-
shield can damage the wiper blades.
— The windshield wiper system must be
switched off (lever in position 0) before us-
ing a car wash. This prevents the wipers
from switching on unintentionally and caus-
ing damage to the windshield wiper system.
@ Tips
— The windshield wipers switch off when the
ignition is switched off. You can activate the
windshield wipers after the ignition is
switched on again by moving the windshield
wiper lever to any position.
— Worn or dirty windshield wiper blades result
in streaking. This can affect the rain sensor*
function. Check your windshield wiper
blades regularly.
— The washer fluid nozzles in the windshield
washer system are heated* at low tempera-
tures when the ignition is on.
— When stopping temporarily, such as ata
traffic light, the speed of the windshield
wipers automatically reduces by one level.
Cleaning windshield wiper blades
Clean the wiper blades when you see wiper
streaks. Clean the wiper blades with a soft towel
and glass cleaner.

Sitting correctly and safely

Safety belts
Each seat is equipped with a three-point safety
belt. Safety belts that are worn correctly are the
most effective way to reduce the risk of serious or
fatal injuries in a collision. Therefore, wear your
safety belt correctly and make sure that all vehi-
cle passengers are also wearing their safety belts
correctly when the vehicle is moving.
Even though your vehicle is equipped with an air-
bag system, every vehicle passenger must still al-
ways wear the appropriate safety belt. In addition
to their normal protective function, safety belts
also hold vehicle occupants in the correct seating
position in the event of a collision so that the air-
bags can deploy correctly and provide additional
protection. Safety belts provide protection during
collisions when the airbags do not deploy or if
they have already deployed.

Z\ WARNING
The risk of serious or fatal injury increases if
the safety belt is not fastened, if it is worn in-
correctly, or if it is damaged.
— All vehicle occupants, including the driver,
must fasten their safety belts correctly be-
fore every trip and must always keep their
safety belts fastened during the trip, re-
gardless of whether the seat is equipped
with an airbag or not. This also applies to
children that are seated in a child safety
seat that is appropriate for their weight and
age and that is secured with a safety belt.
— In the event of a collision, vehicle occupants
that are not wearing safety belts could be
propelled through the vehicle interior and
collide with vehicle components, such as the
steering wheel, instrument panel, wind-
shield, or doors. In some situations, vehicle
occupants could also be ejected from the ve-
hicle. Vehicle occupants who do not wear
safety belts not only endanger themselves,
but also other people in the vehicle.
— Only one person may be fastened with a
safety belt at a time. Never secure more



than one person, including children, with a
single safety belt.
— Never allow children or infants to ride on an-
other person's lap and be belted into the
safety belt with them.
— Insert the belt buckle only in the belt latch
belonging to the corresponding seat, so that
the protective function is not impaired.
— To ensure the maximum protective function
of the safety belts, all vehicle passengers
must sit in the correct seating position
=> page 45.
— Check the condition of your vehicle’s safety
belts regularly > page 237. If you find dam-
age to the belt webbing, the belt connec-
tions, the retractor, or the buckle, have the
damaged safety belt replaced by an author-
ized Audi dealer or authorized Audi Service
Facility.
—The safety belts must not be removed or
modified in any way. Do not attempt to re-
pair the safety belts yourself.
— Safety belts that are strained during an acci-
dent must be replaced by an authorized
Audi dealer or authorized Audi Service Facili-
ty.

Sitting correctly and safely

The locations of the airbags are labeled with
“AIRBAG”. The following airbags are installed in
your vehicle:
Driver's airbag
Front passenger's airbag
Side airbags
Applies
to: Coupe: Head curtain airbag with
ejection mitigation
©
©0080
Knee airbags
Airbags offer the best possible protection in your
vehicle during an accident when they are used to-
gether with safety belts that are fastened cor-
rectly, and when passengers are sitting in the
correct seating position. Airbags are a supple-
mentary restraint system and do not replace
safety belts.
Applies to: Coupe: Airbags may deploy during
head-on, side-impact, or rollover collisions.
Applies to: Roadster: Airbags may deploy during
head-on or side-impact collisions.
The deployment area for the airbag system can-
not be defined for every situation, since the cir-
cumstances surrounding accidents can vary wide-
ly. Factors that play an important role include the
condition of the object that the vehicle hits (hard
or soft), the angle of impact, vehicle speed, etc.
The deciding factor for the deployment of the air-
bag system is the deceleration that occurs during
an accident. Sensors in the vehicle are designed
to detect the severity of an accident in conjunc-
tion with the control module, and to provide a
targeted and timely deployment of the restraint
system. If the vehicle deceleration that is meas-
ured during an accident is below the specified
reference values in the control module, then the
airbags will not deploy, even though the vehicle
may be severely damaged from the accident. In
these cases, the vehicle occupants will be pro-
tected by the safety belts if they are fastened and
worn correctly.
The deployment of the front passenger's airbag
will depend on the occupancy of the seat
=> page 55.
Each deployed airbag is filled with gas. When this
occurs, the airbag covers open and the airbags

unfold with great force into the deployment zone
within milliseconds. Inflated airbags reduce the
movement of passengers wearing safety belts in
the direction of the impact and thus help to re-
duce the risk of injury. They can help to protect
the head, upper body, and lap, for example. How-
ever, there is the possibility that airbag deploy-
ment can cause injuries.
The airbag system only works when the ignition
is turned on.
If you or other vehicle passengers have physical
limitations that prevent sitting in a correct posi-
tion, modifications to the vehicle may be neces-
sary. For more information, contact an author-
ized Audi dealer or authorized Audi Service Facili-
ty, or call Audi customer support at
1-800-822-2834.
) Tips
Applies to: Coupe
The side curtain airbags in your vehicle have
ejection mitigation functions. This reduces
the risk of being ejected from the vehicle inte-
rior during an accident, especially in the event
of a vehicle rollover.
Advanced airbag system

Fig. 62 Headliner: indicator light to display the status of
the front passenger's airbag
The Advanced Airbag System in your vehicle has
been certified to comply with the requirements
of the United States Federal Motor Vehicle Safety
Standard (FMVSS) 208, as well as Canada Motor
Vehicle Safety Standard (CMVSS) 208 as applica-
ble at the time your vehicle was manufactured.
According to these requirements, the front Ad-
vanced Airbag System on the passenger’s side

Storage and convenience


— Never drive with containers that contain hot
liquid such as coffee or tea. The hot liquid
could spill and cause burns during a colli-
sion, sudden braking or other vehicle move-
ment. Spilled hot liquid can also increase
the risk of accidents and injuries.
— Only use soft containers in the cup holders.
Hard cups and glasses can increase the risk
of injury during a collision.
— Never use the cup holder or the adapter as
an ashtray because this is a fire hazard.

@) Note
Beverage containers in the cup holders should
always
have a lid. Otherwise, the liquid inside
could spill and cause damage to vehicle
equipment.
Storage areas and
compartments
Depending on vehicle equipment, there are a va-
riety of storage areas, compartments, and retain-
ers, such as the glove compartment, for safely
storing and securing objects.

ZA\ WARNING
—To reduce the risk of injury, make sure all
storage compartments are always closed
while driving.
— Loose objects can be thrown around the ve-
hicle interior during sudden driving or brak-
ing maneuvers, which increases the risk of
an accident. Store objects securely while
driving.
— Only use the storage compartments in the
door trim panels to store small objects that
will not stick out of the compartment and
impair the function of the side airbags.
— Make sure your view toward the rear is not
blocked, for example by hanging clothing or
objects in the vehicle.
— Applies to: Coupe: No heavy or hard objects
may be placed on the storage compartment
behind the rear seat backrest. There is a risk
of
injuring the vehicle passengers when
braking suddenly.

64
— Applies to: Coupe: Only lightweight clothing
should be hung from the garment hooks in
the vehicle. Do not use clothes hangers to
hang clothing. The pockets of the clothing
must not contain any heavy, breakable, or
sharp-edged objects. This could impair the
effectiveness of the side curtain airbags.
() Note
Applies to: Coupe

Make sure that the heating grid strips for the
rear window defogger are not damaged by
abrasive objects.
Luggage compartment
General information
All pieces of luggage or objects must be securely
fastened in the luggage compartment. Note the
following to maintain good vehicle handling:
> Distribute the load evenly in the luggage com-
partment.
> Stow heavy luggage as far forward in the lug-
gage compartment as possible.
» Use non-elastic cords attached to the tie-downs
to secure objects.

ZX WARNING
— Loose objects can be thrown around the ve-
hicle interior during sudden driving or brak-
ing maneuvers, which increases the risk of
an accident. Always stow objects securely in
the luggage compartment and secure them
at the tie-downs. Use straps suitable for
heavy objects.
— If pieces of luggage or objects are secured to
the tie-downs with unsuitable or damaged
straps, this can increase the risk of injury
during braking maneuvers or accidents.
— When transporting heavy objects, the vehi-
cle characteristics will change due to the
shift in the center of gravity, which increases
the risk of an accident. You may need to
adapt your driving style and speed to the
current conditions.

Assist systems

General information
Applies to: vehicles with Audi side assist

BFV-0260


BFV-0082

Fig. 101 Rear of the vehicle: position of the sensors (exam-
ple)
Side assist functions at speeds above approxi-
mately 19 mph (30 km/h).
@ Approaching vehicles
In certain cases, a vehicle will be classified as crit-
ical for a lane change even if it is still somewhat
far away. The faster a vehicle approaches, the
sooner the display in the outside mirror will turn
on.
@ Vehicles traveling in the same direction as
your vehicle
Vehicles traveling in the same direction as your
vehicle are indicated in the exterior mirror if they
94
are classified as critical for a lane change. All
vehicles detected by side assist are indicated by
the time they enter your “blind spot”, at the lat-
est.
@ Vehicles you are passing
If you slowly pass a vehicle that side assist has
detected (the difference in speed between the ve-
hicle and your vehicle is less than 9 mph (15 km/
h)), the display in the exterior mirror turns on as
soon as the vehicle enters your blind spot.
The display will not turn on if you quickly pass a
vehicle that side assist has detected (the differ-
ence in speed is greater than 9 mph (15 km/h)).
Functional limitations
The radar sensors are designed to detect the left
and right adjacent lanes when the road lanes are
the normal width. In some situations, the display
in the exterior mirror may turn on even though
there is no vehicle located in the area that is criti-
cal for a lane change. For example:
— If the lanes are narrow or if you are driving on
the edge of your lane. If this is the case, the
system may have detected a vehicle in another
lane that is not adjacent to your current lane.
— If you are driving through a curve. Side assist
may react to a vehicle that is one lane over from
the adjacent lane.
—If side assist reacts to other objects (such as
high or displaced guard rails).
— In poor weather conditions. The side assist
functions are limited.
Do not cover the radar sensors > fig. 7107 with
stickers, deposits, bicycle wheels or other ob-
jects, because they will impair the function. For
information on cleaning, see > page 236.

ZA\ WARNING
— Always pay attention to traffic and to the
area around your vehicle. Side assist cannot
replace a driver's attention. The driver alone
is always responsible for lane changes and
similar driving maneuvers.
— In some situations, the system may not
function or its function may be limited. For
example: >
