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

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.

reached operating temperature yet. You
could damage the engine.
— If the engine has been under heavy load for
an extended period of time, heat builds up
in the engine compartment after the engine
is switched off and there is a risk of damag-
ing the engine. For this reason, let the en-
gine run at idle for approximately two mi-
nutes before shutting it off.
@ Tips
— Brief noises are normal when starting and
stopping the vehicle and are no cause for
concern.
— For up to 10 minutes after stopping the en-
gine, the radiator fan may turn on again au-
tomatically or it may continue to run, even if
the ignition is switched off.
— It may not be possible to start the vehicle in
extremely low temperatures.
— Power will be fully available once the engine
is at operating temperature.

When driving

Starting to drive, stopping, and parking
Starting from a stop
>» Press and hold the brake pedal.
> Start the engine.
> Select a gear.
> Release the parking brake.
> Release the brake pedal. The vehicle may roll.
> Press the accelerator pedal to accelerate.
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.

vents too much stress from being placed on the
locking mechanism.

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

8W1012721BB
Driving

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
Requirement: the ignition must be switched on.
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 (2) on the selector lever.
— The “P” next to the selector lever will light up.
“P” engages automatically if you switch the en-
gine off while the “D” or “R” gear is selected. If
you switch the engine off in “N”, “P” will engage
automatically after approximately 30 minutes.
If you want to switch from “P” to “D” or “R”, the
engine must be running.
If you cannot shift out of “P”, for example be-
cause the vehicle has no power, you may need to
use the emergency release for the parking lock
=> page 97.
Selecting a driving program
Various driving programs can be selected when in
the “D” gear. The programs influence when the
transmission shifts and how the accelerator ped-
al responds.
The selected driving program is displayed in the
instrument cluster.
— D (Drive): normal driving mode
—S (Sport): sporty driving mode
If you select the Dynamic mode in Audi drive se-
lect*, the “S” driving program will be activated.
When the ignition is switched off, the driving pro-
gram may be reset to “D”.
To switch between the current driving program
and “S”, push the selector lever toward the rear.

ZX WARNING
— Before starting to drive, check if the desired
gear is displayed next to the selector lever.
— 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.
— Power is still transmitted to the wheels
when the engine is running at idle. To pre-
vent the vehicle from “creeping”, you must
keep your foot on the brake in all selector
lever positions (except "P" and "N") when
the engine is running.
—To reduce the risk of an accident, do not
press the accelerator pedal when changing
gears if the vehicle is stationary and the en-
gine is running.
— 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.

G) 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.
