Instrument cluster

Reducing the display
Depending on the vehicle equipment, you can
hide the central area in the instrument cluster.
> Select on the instrument cluster: vehicle func-
tions tab > E] button > Reduced display.
Coolant temperature
display
Applies to: vehicles with a coolant temperature indicator
The coolant temperature display @ > page 12
only functions when the ignition is switched on.
To reduce the risk of engine damage, please ob-
serve the following notes about the temperature
ranges.
Cold range
If only the LEDs at the bottom of the gauge turn
on, the engine has not reached operating tem-
perature yet. Avoid high engine speeds, full accel-
eration, and heavy engine loads.
Normal range
The engine has reached its operating tempera-
ture once the LEDs up to the center of the gauge
turn on. If the | indicator light in the instru-
ment cluster display turns on, the coolant tem-
perature is too high > page 281.
@) Note
— Auxiliary headlights and other accessories in
front of the air intake impair the cooling ef-
fect of the coolant. This increases the risk of
the engine overheating during high outside
temperatures and heavy engine load.
— The front spoiler also helps to distribute
cooling air correctly while driving. If the
spoiler is damaged, the cooling effect will
be impaired and the risk of the engine over-
heating will increase. See an authorized
Audi dealer or authorized Audi Service Fa-
cility for assistance.
Tachometer
The tachometer (@) 9 page 12 displays the engine
speed in revolutions per minute (RPM). The be-
ginning of the red zone in the tachometer indi-
14
cates the maximum permissible engine speed for
all gears once the engine has been broken in. Be-
fore reaching the red zone, you should shift into
the next higher gear, select the "D" or "S" selec-
tor lever position, or remove your foot from the
accelerator pedal.
Displaying the tachometer
Applies to: vehicles with plug-in hybrid drive
> Applies to: MMI: Select on the home screen:
SETTINGS > Display & brightness > Audi virtu-
al cockpit > Left dial > Tachometer or Com-
bined.
Engine speed limitation
If the Bw indicator light turns on, the engine will
be automatically limited to the RPM displayed in
the instrument cluster. This will protect the en-
gine components, for example during a cold start
or from overheating.
The engine speed limitation is deactivated if you
release the accelerator pedal while the engine is
at normal operating temperature.
If the engine speed limitation was activated by
an engine control malfunction, the indicator
light also turns on. Make sure the engine speed
does not go above the speed displayed, for exam-
ple when downshifting. Drive to an authorized
Audi dealer or authorized Audi Service Facility im-
mediately to have the malfunction corrected.
C) Note
The needle in the tachometer may only be in
the red area of the gauge for a short period of
time before there is a risk of damaging the
engine. The location where the red zone be-
gins varies depending on the engine.

ous or fatal injury.




RAZ.0089)



The locations of the airbags are labeled with
“AIRBAG”. The following airbags are installed in
your vehicle:
@ Driver's airbag
@ Front passenger's airbag
@® Front and rear side airbags
@ Head curtain airbag with ejection mitigation
Fig. 73 Airbag overview image (enlarged section: deployed airbags)
© Front and rear central airbags in some mod-
els
© 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
8s

Sitting correctly and safely

correct seating position. Airbags are a supple-
mentary restraint system and do not replace
safety belts.
Airbags may deploy during front-impact, side-im-
pact, or rollover accidents.
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 86.
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-
86
ty, or call Audi customer support at
1-800-822-2834.
G) Tips
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. 74 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
has been certified for “suppression” for infants
approximately 12 months old and younger, and
for “low risk deployment” for children aged 3 to
6 years old (as defined in the standard).
The advanced airbag system will activate or deac-
tivate the front passenger's airbag based on the
occupancy of the seat. If a front airbag deploys
during an accident, the deployment force will
adapt to the passenger.
Components
The advanced airbag system consists of the fol-
lowing components:
— Front airbags in the steering wheel and in the
instrument panel on the front passenger's side: >
