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.
— 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 con-
tain any heavy, breakable, or sharp-edged
objects. This could impair the effectiveness
of the side curtain airbags.
— Make sure your view toward the rear is not
blocked, for example by hanging clothing or
objects in the vehicle.

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.

A WARNING
— Applies to: vehicles with luggage compart-
ment cover: The luggage compartment >

Storage and convenience


cover is not a surface for storing objects. Ob-
jects placed on the cover increase the risk of
injury to all vehicle occupants during sudden
driving or braking maneuvers or in the event
of an accident.
— Applies to: vehicles with luggage compart-
ment cover: The luggage compartment cov-
er must always be securely fastened when in
use to reduce the risk of an accident.
— 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 dam-
aged straps, this can increase the risk of in-
jury 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.
— The cargo net* is only strong enough to se-
cure light objects. Heavy objects are not ade-
quately secured. Attempting to secure heavy
objects increases the risk of injury.
— Never exceed the permitted axle and load
and vehicle weight > page 291.
— Never secure a child safety seat to the tie-
downs.
— Never leave your vehicle unattended, espe-
cially if the luggage compartment lid is
open. Children could enter the luggage com-
partment and close the luggage compart-
ment lid from the inside. This creates the
risk of fatal injury, since the children would
be locked in and may not be able to escape
by themselves.
— Do not allow children to play in or on the ve-
hicle. Close and lock the luggage compart-
ment lid as well as all other doors when you
leave
the vehicle.
— Never transport passengers in the luggage
compartment. Every passenger must be cor-


rectly secured with the safety belts in the
vehicle > page 64.
— Be careful when releasing the backrest and
folding
it forward. To reduce the risk of be-
ing pinched, pay attention and check when
folding backrests forward.
— The backrest must be securely latched so
objects cannot slide forward out of the lug-
gage compartment during sudden braking.
— The backrest must be latched securely to en-
sure that the safety belt is protecting the
center seating position.
— Always pull forward on the backrest to make
sure it is check if it is correctly locked in
place.

@) Note
—To reduce the risk of damage, move the rear
head restraints down > page 63 before fold-
ing the rear backrests forward.
— When folding the backrest forward, make
sure the outer safety belts are in the belt
guide recess so that they do not get pinched
in the backrest lock and damaged. Other ob-
jects should be removed from the rear
bench seat to protect the backrest from
damage.
— If you move the front seat back when the
rear seat backrest is folded forward, you
could damage the head restraints on the
rear seat.
— Make sure that the heating grid strips for
the rear window defogger are not damaged
by abrasive objects.
— Applies to: vehicles with manual luggage
compartment cover: Let the luggage com-
partment cover roll up slowly to reduce the
risk of damage.
@ Tips
— The tire pressure must be adapted to the
load > page 251.
— You can purchase straps at specialty stores.

Roof rack
General information
Applies to: vehicles with roof rack mount




Fig. 77 Roof rail: mounting points
If luggage or cargo is to be carried on the roof,
you must observe the following:
— These roof racks are the basis for a complete
roof rack system. Only roof racks that are suita-
ble for your vehicle may be used. Audi recom-
mends roof racks and attachments from the
Audi Genuine Accessories program.
— Make sure the roof rack is mounted on the vehi-
cle only at the specified locations @.
— Note the permitted axle load, permitted total
weight, and permitted roof load of your vehicle
= page 291. The roof load is the total of the
weight of the roof rack, the attachments and
the cargo you are carrying. However, you must
also note the permitted load of the carrier sys-
tem being used.

Z\ WARNING
— Follow the installation instructions provided
with the roof rack system. If you do not se-
cure the roof rack system and objects on the
roof correctly, they could come loose from
the vehicle and cause an accident.
—The risk of an accident increases when using
a roof rack system, because it changes the
driving characteristics by shifting the center
of gravity and/or the increasing the surface
area exposed to wind. You may need to
adapt your driving style and speed to the
current conditions.
® Note
Make sure that the luggage compartment lid
and the panoramic glass roof* do not come in-
to contact with objects on the roof when they
are open.

(@) For the sake of the environment
Energy usage will increase because of the in-
creased wind resistance. Remove the roof rack
when you are no longer using it.

Fig. 79 Center console: switching on the drive system
Your vehicle is powered by electricity. Similar to a
vehicle with a combustion engine, the ignition
and drive system can be switched on separately.
When only the ignition is switched on, electronic
systems such as the MMI are available. However,
the vehicle is not ready to drive. Electric power is
able to move the vehicle once the drive system is
switched on and becomes active.
Requirement: the key must be in the vehicle.
Switching the drive system on
> Press and hold the brake pedal.
> Press the [START STOP] button. The drive sys-
tem switches on.


It is indicated in the power meter whether the
drive system is switched on > page 13.
Switching the drive system off
> Bring the vehicle to a full stop.
> Press the [START STOP] button. The drive sys-
tem switches off.


The steering is locked when you switch off the
drive
system in “P” and open the driver's door.
The steering lock helps prevent vehicle theft.
Switching the drive system off in an
emergency
If necessary in an emergency, the drive system
can also be switched off while driving using the
emergency off function*.
90

> Press the [START STOP] button twice in a row or
press and hold it one time.

Switching on and off
If you would like to switch the ignition on or off
without switching on the drive system, follow
these steps:

> Press the [START STOP] button without pressing
the brake pedal.

Switching the ignition off automatically
To prevent the vehicle battery from draining, the
ignition and possibly the exterior lighting may
switch off automatically.
Requirements:
— You must have driven the vehicle.
— You must have left the vehicle for longer than
30 seconds.
— The ignition must be switched on.
Among other indicators, the system detects that
you have left the vehicle based on the following
factors:
— The driver's door has been opened.
— The driver's safety belt has been unbuckled.
— The brake pedal is not being pressed.
— The driver's seat is not occupied.
The ignition will also be switched off after 30 mi-
nutes or if you lock the vehicle from the outside.

ZA WARNING
— Never switch off the drive system before the
vehicle has come to a complete stop.
Switching it off before the vehicle has stop-
ped may impair the function of the brake
booster and power steering. You would then
need to use more force to steer and brake
the vehicle. The fact that you cannot steer
and brake as usual may increase the risk of
accidents and serious injuries.
— Secure the vehicle against rolling before ex-
iting the vehicle > page 91. >

Starting from a stop
> Press and hold the brake pedal.
> Switch on the drive system.
> 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.
Securing the vehicle against rolling
Secure your vehicle to prevent it from rolling be-
fore exiting the vehicle.
>» Set the parking brake.
> Select the “P” selector lever position.
> If parking on a steep road, turn the steering
wheel so that your vehicle will roll against the
curb in case it should start to move.
If one of these measures is not possible, for ex-
ample because there is no vehicle power, you
must secure your vehicle against rolling using ad-
ditional measures.
> Only park the vehicle on a level surface.
> Use suitable objects to block the front and rear
wheels.
Set the parking brake before selecting the “P” se-
lector lever position. This prevents too much
stress from being placed on the locking mecha-
nism when parking on a steep surface.

ZA WARNING
— Always set the parking brake when leaving
your vehicle, even if for a short period of
time. If the parking brake is not set, the ve-
hicle could roll away, increasing the risk of
an accident.
— Do not leave your vehicle unattended while
the drive system is active, because this in-
creases the risk of an accident. >

“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.
— Secure the vehicle against rolling before ex-

iting the vehicle > page 91.

— 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” 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.
