> Select a gear.
> Release the parking brake.
> Release the brake pedal.
> Press the accelerator pedal to accelerate.
Always make sure that the vehicle does not
“creep” when starting to drive and maneuvering.
If you take your foot off the brake pedal, the ve-
hicle will not be set into motion by the drive sys-
tem.
Stopping and parking
> Bring the vehicle to a full stop and press and
hold the brake pedal.
> Set the parking brake.
> Select the “P” selector lever position to secure
the vehicle from rolling away.
» Turn the steering wheel when parking on in-
clines so that the wheels will roll into the curb
if the vehicle starts moving.
> Switch off the ignition before leaving the vehi-
cle.
On hills, activate the parking brake first and then
shift into the "P" selector lever position. This pre-
vents too much stress from being placed on the
locking mechanism.

Driving

“N” (Neutral) gear
In the “N” gear, power is not transmitted to the
driving wheels. Use the “N” gear in a car wash
(with conveyor belts), for example.
If you unintentionally select “N” while driving
(faster than 1 mph (2 km/h)), you can also shift
back to “D” without pressing the brake pedal.
For safety reasons, the vehicle cannot be locked
when the transmission is in the "N” gear.
“Pp” (Park) gear
The vehicle is secured from rolling away by the
parking lock when in the “P” gear.
— Bring the vehicle to a full stop and press the
brake pedal.
— Press the “P” button @ on the selector lever.
— The “P” next to the selector lever will light up.
“P” engages automatically if you switch the drive
system off while the “D” or “R” gear is selected.
If you switch the drive system off in “N”, “P” will
engage automatically after approximately 30 mi-
nutes.
If you want to switch from “P” to “D” or “R”, the
drive system must be active.
Selecting the driving program
Various driving programs can be selected when in
the “D” gear. The programs influence how the ac-
celerator pedal and drive system respond.
If you select the dynamic or offroad Audi drive
select* mode, the “S” driving program will be ac-
tivated. If you select efficiency, “E” will be acti-
vated. When the ignition is switched off, the driv-
ing program may be reset to “D”.
To switch between the current driving program
and “S”, push the selector lever toward the rear.

ZA WARNING
— Before you start driving, check if the label
for the desired selector lever position next
to the selector lever is lit up.
— Always secure your vehicle from rolling
away. Press the brake pedal or shift to “P”.
When leaving the vehicle, also set the park-

ing brake.


— To reduce the risk of an accident, do not
press the accelerator pedal when changing
gears if the vehicle is stationary and the
drive system is active.
— Never select the “R" or "P” gears while driv-
ing. Doing so could cause an accident.
—The vehicle can roll even if the ignition is
switched off.
(Gi) Tips
If you shift between “D” and “R” within one
second, you do not need to press the brake
pedal. This makes it possible to “rock” the ve-
hicle if it is stuck, for example.
Accelerator pedal
You can accelerate the vehicle using the accelera-
tor pedal.

Maximum acceleration
If you press the accelerator pedal all the way
down, the motor’s full power will be used and
you will reach maximum acceleration, also called
“kick-down”.
Applies to: vehicles with boost function: In the
“S” driving program, even more power is utilized
for a brief period of time via the boost function.
The availability of this function depends on the
charge level of the high-voltage battery and the
temperature of the drive system components,
among other things.

Z\ WARNING
The driving wheels could spin and the vehicle
could swerve on slick or slippery road surfaces
when using kick-down, which increases the
risk of an accident.
Launch Control
Applies to: vehicles with Launch Control

Launch Control provides the best possible accel-
eration when starting from a stop.

Driving

Requirements
— Driving program “S” > page 91 or the dynamic
Audi drive select* mode must be selected
=> page 101.
— The boost function is available > page 91.
Using Launch Control
— Press the brake pedal with your left foot and
hold it all the way down for at least one second.
— With the brake pedal pressed, press the accel-
erator pedal all the way down with your right
foot at the same time.
— As soon as the colored edge of the power meter
actively flashes, remove your foot from the
brake pedal.

ZA WARNING
Only use Launch Control when road and traffic
conditions allow it and other road users will
not be endangered or impacted by your driv-
ing and the vehicle's acceleration. The driving
wheels could spin and the vehicle could
swerve, especially on slick or slippery road
surfaces, which increases the risk of an acci-
dent.
@) Note
When accelerating using Launch Control, all
vehicle components are subject to heavy
loads. This can result in increased wear.
G) Tips
After accelerating using the Launch Control,
the temperature of some vehicle components
may increase greatly. If that happens, the
function will not be available for a few mi-
nutes to reduce the risk of damage. After a
cool-down period, Launch Control will be
available again.

Drive system
ada ee tee Tn)
Vehicles with an electric drive system are pow-
ered by an electric motor. The drive power de-
pends on the temperature and the charge level of
the high-voltage battery.
The vehicle is able to recover energy by using “re-
cuperation”. The electric drive system operates
like a generator and converts a large portion of
kinetic energy into electrical energy that is stored
in the high-voltage battery. The vehicle is braked
during recuperation, which is similar to the >

Driving

engine braking effect on a vehicle with a combus-
tion engine. This will happen automatically when
you press the brake pedal while driving in “D”
gear, or when you remove your foot from the ac-
celerator pedal.
When you press the brake pedal, recuperation is
used to brake the vehicle. The brakes will only be
activated if necessary. When driving normally,
this makes it possible to brake using only recu-
peration just before coming to stop and to lose
little energy and range from braking.
Setting options
You can set how strongly the vehicle should be
braked by recuperation while coasting.
> Applies to: MMI: Select on the home screen:
VEHICLE > Charging & Efficiency > Efficiency
assist > Recuperation.
Automatic: the recuperation braking effect is ad-
justed proactively* to the route or vehicles driv-
ing ahead, for example. You can temporarily ad-
just the braking effect by selecting a recuperation
level with the shift paddles.
Manual: the recuperation braking effect is con-
trolled manually. You can select a recuperation
level using the shift paddles.
Settings using the shift paddles:
> Select © for a stronger braking effect.
>» Select @ for a weaker braking effect.


Z\ WARNING
In certain situations, the recuperation may
brake proactively. However, the recuperation
braking effect is limited. Always be ready to
brake to reduce the risk of an accident.

@ Tips
If the ESC is limited or switched off, automat-
ic recuperation is not available and will not
brake.

Range potential: the value indicates an addition-
al amount of distance that can be gained by turn-
ing off certain convenience functions. The con-
venience functions with high energy usage are
listed on
the display.
Range mode: to maximize the current range, you
can use the button to switch the vehicle to a
mode with less energy consumption. This will re-
duce the drive system power and the maximum
speed. This can also turn off certain energy con-
sumers. You can exit this mode by either pressing
the button again, pressing the Audi drive select*
button, or switching off the ignition.
G) Tips
— The range can also be displayed in the in-
strument cluster in the on-board computer.
— The range that is indicated is based on the
previous and predicted consumption values.
For example, this may influence the naviga-
tion route guidance or activated conven-
ience functions.

Driving

Vehicle sound
The electric drive system generates considerably
less noise than a combustion engine. An artificial
engine sound is generated when driving electri-
cally so that the vehicle can be heard from the
outside when driving. The vehicle sound auto-
matically fades out at higher speeds when the
sounds from the tires and wind start increasing.

ZA WARNING
Other road users may not be able to defini-
tively hear electric vehicles when they are
driving. This increases the risk of an accident
particularly when driving in areas with little
traffic, when maneuvering, or when driving in
reverse.

IAT eMaL eLUN or da aCe

Your driving style greatly influences the amount
of fuel and energy consumed, the environmental
impact, and the wear on the motor, brakes, and
tires. Note the following information for efficient
and environmentally-conscious driving:
— Select the Audi drive select* efficiency mode.
— 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 drive with winter tires during the summ-
er.
— Brake early and evenly to use recuperation.

Brakes
General information
You can apply the vehicle's brakes using the brake
pedal.
Operating noise
Noises may occur when braking depending on the
speed, braking force, and outside conditions such
as temperature and humidity.
When the vehicle is stationary, the brake system
performs system tests at regular intervals. This
can cause brief noise and haptic feedback effects
on the brake pedal.
Braking effect
The response time from the brakes depends on
the weather and environmental conditions. To
ensure the optimal braking effect, the brake >

4KE012721BE
Driving

system is cleaned at regular intervals. This is
done by applying the brake pads to the brake ro-
tors for a short period of time when driving at
high speeds when the windshield wipers are
switched on.
If the brake system becomes damp, for example
after driving in heavy rain, the braking effect may
be delayed. Other factors that could temporarily
increase the response time of the brakes include:
— Wet conditions
— Low temperatures, ice, and snow
— Roads covered in salt
— Dirty brake pads
Corrosion
Corrosion may form on the brake rotors if there is
no heavy braking, if the vehicle is not driven for
long periods of time, or if the vehicle is not driv-
en
frequently or for long distances. In this case,
braking heavily several times while driving at
high speeds can clean the brake rotors > A\.
To do this, select the “N” gear so that recupera-
tion is not used for braking.
Brake pads
New brake pads do not achieve their full braking
effect during the first 500 miles (800 km). They
must be “broken in” first. However, you can com-
pensate for the slightly reduced braking force by
pressing firmly on the brake pedal. Avoid heavy
braking during the break-in period.
Because recuperation is also used for braking, the
break-in period for new brake pads is 500 miles
(800 km).
Brake pad wear depends largely on the way the
vehicle is driven and on operating conditions.
Brake pad wear increases when driving frequently
in the city or short distances or when using a very
sporty driving style.
Automatic post-collision braking system
The automatic post-collision braking system can
help to reduce the risk of sliding and of addition-
al collisions after an accident. If the airbag con-
trol module detects a collision, the vehicle is
braked by the ESC.
The vehicle does not brake automatically if one of
the following occurs:
— The driver presses the accelerator pedal, or
— The braking force generated by the pressed
brake pedal is greater than the braking force
that would be initiated by the system
—The ESC, the brake system, or the vehicle elec-
trical system is not functioning

Z\ WARNING
— Only apply the brakes for the purpose of
cleaning the brake system when road and
traffic conditions permit. You must not en-
danger other road users and increase the
risk of an accident.
— Due to the risk of injury, only have an au-
thorized Audi dealer or authorized Audi
Service Facility work on the brake system.
Incorrect repairs could impair the function.
— Never let the vehicle roll while the drive sys-
tem is switched off because this increases
the risk of an accident.
— During automatic braking maneuvers, the
brake pedal may move downward automati-
cally. To 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.

— Observe the important information for driv-
ing downhill > page 98. This especially ap-
plies
when towing a trailer.
@ 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 243.
