-Some noise after starting the engine is nor­
mal and is no cause for concern.
- If you leave the vehicle with the ignition
switched on, the ignition will switch off af­
ter a certain amount of time. Make sure that
electrical equipment such as the exterior
lights are switched off.
Stopping the engine
"'Bring the vehicle to a full stop.
"'Select the P or N selector lever position.
"'Press the
I START ENGINE STOPI button

Steering lock
The steering locks when you turn the engine off
using the
I START ENGINE STOPI button and
open the driver's door. The locked steering helps
prevent vehicle theft.
Emergency off function
If it is absolutely necessary, the engine can also
be turned off while driving in the R, Dor S selec­
tor lever position at speeds below 6 mph (10 km/
h). To stop the engine, press and hold the
I START ENGINE STOPI button and also press the
brake pedal.
& WARNING
-Never turn off the engine before the vehicle
has come to a complete stop. The full func­
tion of the brake booster and the power
steering is not guaranteed. You must use
more force to turn or brake. Because you
cannot steer and brake as you usually
would, this could lead to accidents and seri­
ous injuries .
- Always take the key with you whenever you
leave your vehicle. Otherwise, the engine
could be started or electrical equipment
such as the power windows could be operat­
ed. This can lead to serious injury.
- For safety reasons, always park the vehicle
with the selector lever in the P position.
Driving
Otherwise, there is the risk that the vehicle
could roll unintentionally.
@ Note
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 damaging
the engine. For this reason, let the engine run
at idle for approximately two minutes before
shutting it off.
(D Tips
After the engine has been switched off, the
radiator fan can continue to run for up to 10
minutes -even with the ignition switched off .
It can also switch on again after some time if
the coolant temperature rises as the result of
heat buildup or if the engine is already warm
and the engine compartment is also heated
by the sun's rays.

Trailer mode
Trailer load distribution
Be s ure the load in the trailer is held securely in
p lace to prevent it from shifting forward, back­
ward or sideways .
Never allow a passenger to ride in a trailer¢.&.
in Driving instructions on page 91.
Engine cooling system
Towing a trailer makes the eng ine work harder . It
is important that the cooling system's perform­
ance is up to the additional load. Make sure that
the cooling system has eno ugh fluid.
Tire pressure
When tow ing a tra iler, inflate the tires of your
veh icle to the tire pressure listed under "Full
load " on the label ¢
page 293 . Inflate trailer
tires to trailer and tir e manufacturers' specifica­
tions.
Lights
Check to make sure both vehicle and trailer lights
are working properly .
Safety chains
Be sure trailer safety chains are properly connect­
ed from the trailer to the hitch on the vehicle. Leave enough slack in the chains to permit turn­
ing corners . When you install safety cha ins, make
sure they w ill not drag on the road when you are
driving.
The chains should cross under the trailer tongue to prevent it from dropping in case of separation
from the hitch.
Adjusting the Audi drive select
Make sure the vehicle is on a level surface before
hitching up the trailer and before adjust ing the
tongue weight. The vehicle must be in
auto or
comfort driving mode and not raised
o:,;, page 110, o:,;, 0 .
Make sure that the vehicle is lowered. In Info­
tainment, select:
ICARI function button> Lower
control button.

If you must drive under poor road conditions, you
can raise the vehicle
after coupling the trailer or
after adjust ing the tongue we ight ¢ page 112.
([) Note
-Changes in temperature or load can affect
the height of the vehicle.
- Always select auto or comfort mode. Other­
wise, the tongue load specified for your ve­
hicle will no longer be app licab le .
Driving instructions
Driving with a trailer always requires extra care
and consideration.
Weight distribution
Towing a loaded trailer with an empty car results
i n a high ly unstable distribution of we ight . If this
cannot be avoided, drive at very low speeds only
to avoid t he risk of losing steering contro l.
A "balanced " rig is easier to operate and control.
This means that the tow vehicle should be loaded
to the extent possible and permissib le, wh ile
keeping the trailer as light as possible under the
circumstances. Whenever possible, transfer
some cargo to the luggage compartment of the
tow veh icle while observing tongue load require­
ments and vehicle loading considerations.
Speed
The higher the speed, the more difficult it be­
comes for the driver to control the rig . Do not
drive at the maximum permissible speed. Reduce
your speed even more if load, weather or wind cond it ions are unfavorable - particularly when
go ing downh ill.
Reduce vehicle speed
immediately if the trailer
shows the slightest sign of sway ing.
Do not try
to stop the swaying by accelerating.
Observe speed limits. In some areas, speeds for
vehicles towing trailers are lower than for regular
vehicles.
Always apply brakes early. When driving down­
hill, shift into a lower gear to use the engine
braking effect to slow the vehicle. Use of the
brakes alone can cause them to overheat and fail. ..,.

Audi active Lane assist
(Lane departure assist)
Description
A ppl ies to: ve hicles w ith Audi active lane assist
Active lane ass ist detects lane marker lines with­
in the l imits of the system us ing a camera in the
windshie ld. If you are approaching a detected
lane marker line and it appears likely t hat you
will leave the lane , the system will warn you with
correct ive steering . You can override t his steer ing
at any time. If you pass over a line, the steering
wheel will vibrate lightly . In order for this warn­
ing vibration to occur, it must first be sw itched
on in the Infotainment system. Act ive lane assist
is ready for operation when the lane marker line
is detected on at least one side of the vehicle.
The system is designed for driving on express­
ways and h ighways and therefore only activates
at speeds above approximately 40 mph (65 km/
h) .
App lies to veh icles with side assist
If you activate a turn signa l when active lane as­
sist is ready and it class ifies a lane change as crit­
ical because of veh icles traveling alongside you or
approaching you, there will be noticeable correc ­
tive steering shortly before you leave the lane .
This will attempt to keep your vehicle in the lane.
A pp lies to veh icles witho ut s ide ass ist
The system will not warn you before crossing a
lane marker line if you have activated the turn
signal. In this case, it assumes that you are
changing lanes intent io nally.
102
App lies to: vehicles wi th adap tive cruise contro l
The corrective steering is targeted based on the
driving situation. In addition to the lane marker
li nes, the system can also take into account other
ob jects such as guard rails. If they are detected in
close prox imity to the ve hicle, active lane assist
helps prevent the vehicle from dr iving too close
to them . There is also pass ing ass istance. The
system does not provide any corrective steering if
i t detects that you are pass ing anothe r vehicle.
.&_ WARNING
- The system warns the drive r that the vehicle
is leaving the lane us ing correct ive steering.
The drive r is always responsible for keeping
the vehicle within the lane.
- The system can assist the dr iver in keeping
the vehicle in the lane, but it does not drive
by itself. A lways keep your hands on the
steer ing whee l.
- Corrective steering may not occur in certain
situations, such as during heavy braking.
- There may be cases where the camera does
not recognize all lane marker lines . Cor rec­
tive stee ring can only take place on the side
of the vehicle where lane marker lines are
detected.
- Other road structures or objects could poss i­
bly be identified un intent ionally as lane
marker lines. As a result, corrective steering
may be unexpected o r may not occ ur.
- The camera view can be restricted, for ex­
ample by vehicles driving ahead or by ra in,
snow, heavy spray or lig ht shining into the
camera. This can resul t in active lane ass ist
no t de tecting the lane marker lines or de­
tect ing them in co rrectly .
- Unde r ce rtain cond it ions su ch as r uts in the
ro ad, a ban ke d roadway or crosswin ds, the
corrective s teer ing alone may not be enough
to keep the vehicle in the m iddle of the lane.
- For safety reasons, a ct ive lane assis t must
no t be use d when there are poor road and/
or weather conditions such as slippery
roads, fog, gravel, heavy rain, snow and the potential for hydrop laning. Using active lane
assist under these cond it ions may increase
the r isk of a crash.

0 co .... N ,..... N .... 0 0 :c ' depends on the driving mode selected, steering
movements, the driver's braking and accelera­
tion, and as the road surface, vehicle speed and load. A sporty setting is generally used in vehicles
with adaptive air suspension sport*.
The vehicle ground clearance depends on the
mode selected and the speed. When you are in
the auto or dynamic mode, the highway setting is
activated when you drive above 75 mph (120 km/
h) for more than 30 seconds. The ground clear­
ance is increased automatically if the speed
drops below 44 mph (70 km/h) for more than 120 seconds .
Steering
The power steering adapts. Indirect steering that
moves easily as in comfort mode is especially
suited to long drives on a highway. The dynamic
mode provides sporty, direct steering .
Applies to: vehicles with dynamic steering
The steering ratio changes based on vehicle
speed in order to maintain optimum steering ef ­
fort for the driver at all times . This sets the steer­
ing to be less sensitive at higher speeds in order
to provide improved vehicle control. At reduced
speeds, steering is more direct in order to keep
the steering effort as minimal as possible when
the driver is maneuvering the vehicle. At low and
average speeds, dynamic steering* additionally
provides more responsive steering performance.
Sport differential*
As a component of the all wheel drive system
(quattro)
~ page 130, the sport differential dis­
tributes the driving power to the rear axle de­
pending on the situation. The distribution of
power varies from balanced (comfort) to sporty
(dynamic) depending on the selected mode. The
goal is a high level of agility and ability to accel ­
erate on curves. The vehicle is very responsive to
steering .
Cornering light*
The cornering light adapts the high beams to the
direction of the curve depending on the speed.
The pivoting action and the lighting also adapt to
the mode .
Assist
Adaptive cruise control*
The behavior when accelerating can be adjusted
from comfortable to sporty, depending on the
drive select mode. Adaptive cruise control also
responds to the driving behavior of the vehicle
ahead in a more conservative or sporty manner.
Engine sound*
The engine sound adapts to the current mode
and can be subtle to sporty.
(D Note
- Make sure there is enough clearance above
and below the vehicle when parking. The
height of the vehicle can change once it is
parked due to temperature fluctuations,
changes to the load conditions and changes
to the driving modes, which can affect clear­
ance.
- When transporting the vehicle on a car car­
rier, train, ship or by other means, only tie
the vehicle down at the running surface of
the tires, which is the outer circumference.
Securing the vehicle at the axle compo­
nents, suspension struts or towing eyes is
not permitted because the pressure in the
air suspension struts can change during
transport. The vehicle may not be secured
sufficiently if this happens.
@ Tips
- In some models, the maximum vehicle
speed can only be reached in the auto and
dynamic modes.
- The S selector lever position automatically
engages if the dynamic mode is selected.
- In vehicles that have dynamic steering*, op­
erating noise is heard when starting or stop­
ping the engine. This does not indicate a
problem.
