Requirement: the light switch must be in the AU-
TO or ZO position.
The headlights automatically adjust so that there
will be less glare, for example when the road sur-
face is wet.
Automatic headlight range control
Your vehicle is equipped with automatic head-
light range control. It reduces glare for oncoming
traffic if the vehicle load changes. The headlight
range adjusts automatically.
Audi adaptive light
Applies to: vehicles with adaptive light
Audi adaptive light provides better visibility when
driving in the dark. The lights are adapted to the
48

road conditions based on speed, such as when
driving on expressways, rural roads, at intersec-
tions, and around curves. The adaptive lights only
function when the light switch is in the AUTO po-
sition and the all-weather lights are switched off.

ZX WARNING
— Follow the safety precautions and note the
limits of the assist systems, sensors, and
cameras > page 114.
— Automatic headlights are only intended to
assist the driver. They do not relieve the
driver of responsibility to check the head-
lights and to turn them on manually based
on the current light and visibility conditions.
For example, fog cannot be detected by the
light sensors. So always switch on the low
beams ZO under these weather conditions

and when driving in the dark.

@) Tips
— If the vehicle battery has been discharging
for a while, the parking light may switch off
automatically. Avoid using the parking
lights for several hours.
— Follow the regulations applicable to the
country where you are operating the vehicle
when stopping the vehicle and when using
the lighting systems.
—Awarning tone will sound if you open the
door when the exterior lights are switched
on.
— Only the front headlights turn on when the
daytime running lights are switched on*. In
vehicles in certain markets, the tail lights
will also turn on.
—Incool or damp weather, the inside of the
headlights, turn signals, and tail lights can
fog
over due to the temperature difference
between the inside and outside. They will
clear shortly after switching them on. This
does not affect the service life of the light-
ing.

Z\ 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.
— Due to strength reasons, only secure objects
up to 11 lbs (5 kg) with the tie-downs*.
Heavier objects are not adequately secured.
There is risk of personal injury.
— Applies to: vehicles with garment hooks: On-
ly lightweight clothing should be hung from
the garment hooks in the vehicle. Do not use
clothes hangers to hang clothing. The pock-
ets of the clothing must not contain 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.
— Applies to: vehicles with storage areas be-
hind the rear head restraints: Do not store
any
heavy or hard objects or use to transport
animals. Such objects endanger vehicle oc-
cupants and increase the risk of injury dur-
ing sudden driving or braking maneuvers or
in an accident.
@) Note
Applies to: vehicles with storage areas behind
the rear head restraints: Make sure the heat-
ing grid strips for the rear window defogger
are not damaged by abrasive objects.
@) Tips
Applies to: vehicles with storage areas behind
the rear head restraints: To ensure the venti-
lation functions correctly, the ventilation slots
between the rear window and the storage
area must not be covered.

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.

ZA\ WARNING
— Applies to: vehicles with luggage compart-
ment cover: The luggage compartment cov-
er 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. >

Stowing and using


— 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 278.
— 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 before folding the rear
backrests forward > page 63.
— 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.
— To reduce the risk of damaging the front
seats, make sure there is enough space be-
tween the front seat and the rear seat
equipment when folding the center backrest
forward.
— 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.
— Applies to: vehicles with partition net: Let
the partition net roll up slowly to reduce the
risk of damage.
(i) Tips
— The tire pressure must be adapted to the
load > page 237.
— You can purchase straps at specialty stores.

Warm and cold
Climate control system
Your vehicle has a deluxe automatic climate con-
trol system with 3 zones where the temperature,
air distribution, and air supply can be set sepa-
rately on the left front side, the right front side,
and in the rear.
The climate control system warms, cools and re-
moves humidity from the air in the vehicle interi-
or. It is the most effective when the windows and
panoramic glass roof* are closed. If there is a
build-up of heat inside the vehicle, ventilation
can help to speed up the cooling process.
In all heating mode functions, except for defrost,
the blower only switches to a higher speed once
the refrigerant has reached a sufficient tempera-
ture.
Pollutant filter
The pollutant filter removes pollutants such as
dust and pollen from the air.
(@) For the sake of the environment
Energy can be saved by switching off the A/C
mode.
@) Tips
—To prevent interference with the heating
and cooling output and to prevent the win-
dows from fogging over, the air intake in
front of the windshield must be free of ice,
snow, and leaves.
— Condensation from the cooling system can
drip and form a puddle of water under the
vehicle. This is normal and does not mean
there is a leak.
— The energy management system may tem-
porarily switch off certain functions, such as
the seat heating* or rear window defogger.
These systems are available again as soon as
the energy supply has been restored.
—The climate control settings are automati-
cally stored and assigned to the vehicle key
that is in use.

Driving information

Driving information
Speed warning system
Applies to: vehicles with speed warning system
The speed warning system helps the driver to
stay below a specified maximum speed. A warn-
ing threshold can be set in the MMI for this pur-
pose.
Once the speed slightly exceeds the stored
threshold, the speed warning system will alert
the driver with an indicator in the instrument
cluster and a warning tone. Once the speed drops
below the stored maximum speed, the indicator
will turn off.
Setting a threshold is recommended if you would
like to be reminded when you reach a certain
maximum speed. Situations where you may want
to do so include driving in a country with a gener-
al speed limit or if there is a specified maximum
speed for winter tires.
@ Tips
Regardless of the speed warning system, you
should always monitor your speed using the
speedometer and make sure you are adhering
to the legal speed limit.

Driver assistance

Driver assistance
Cruise control system
Applies to: vehicles with cruise control system
The cruise control system assists the driver in
maintaining a constant speed above approxi-
mately 15 mph (20 km/h). The system maintains
the desired speed by braking and accelerating.

ZA\ WARNING
— Always pay attention to the traffic around
your vehicle when the cruise control system
is in operation. As the driver, you are always
responsible for controlling your vehicle
speed and the distance between your vehicle
and
other vehicles.
— For safety reasons, cruise control should not
be used in the city, in stop-and-go traffic, on
winding roads, and when road conditions are
poor (such as ice, fog, gravel, heavy rain,
and conditions that could lead to hydroplan-
ing), because this increases the risk of an ac-
cident.
— Switch the cruise control off temporarily
when driving in turning lanes, highway exits,
or in construction zones.
—To reduce the risk of an accident, you should
only resume the stored speed if it is suitable
for the current traffic conditions.


() Note
Before driving downhill a long distance ona
steep hill, decrease your speed and select a
lower gear. This makes use of the engine brak-
ing effect and reduces the load placed on the
brakes.
