¢ Q Turn signals
The indicator light blinks when you use either
turn signal .
Whenever you use the left . or the right 1B
turn s ignal, the indicator light blinks. When
you use the emergency flashers, both indica­
tor lights flash .
If one of the turn signa l light bulbs burn out,
the turn signal will blink twice as fast as nor­
mal. Carefully dr ive to your authorized Audi
dealer immed iately to have the malfunction
corrected. The ind icator light does not indi­
cate a malfunction if a turn signal on the trail­
er or on the vehicle fails in trailer towing
mode.
(D Tips
For more information on the turn signals,
refer to
q page 45.
CRUISE/' (-) Cruise control
The warning/indicator light Ill (USA models)/
l'I (Canada mode ls) illuminates when the
cruise control is activated
q page 82.

44 Clear vision
& WARNING
- Automatic headlights are only intended
to assist the driver . They do not relieve
the driver of his responsibility to check
the headlights and to turn them on man­
ually according to the current light and
visibility conditions. For example, fog
cannot be detected by the light sensors.
So always switch on the headlights
io
under these weather conditions and
when driving in the dark.
- Crashes can happen when you cannot see
the road ahead and when you cannot be
seen by other motorists. Always turn on
theheadlightssothatyoucanseeahead and so that others can see your car from
the back .
- The rear fog lights should only be turned
on in accordance with traffic regulation,
as the lights are bright for following traf­
fic.
- Please observe legal regulations when using the lighting systems described .
@ Tips
-The light sensor* for automatic head­
light range control* is located in the rear
view mirror mount . You should therefore
not apply any st ickers to the windshield
in this area in order to prevent malfunc­
tions or failures.
- In the event of a light sensor malfunc­
tion, the driver is notified in the instru­
ment cluster display
Q page 2 3 .
-You will hear a warning tone if you open
the driver door when the exterior lights
are switched on.
- In cool or damp weather, the inside of
the headlights, turn signa ls and tail
lights can fog over due to the tempera­
ture difference between the inside and
outside. They will clear shortly after
switching them on. This does not affect
the service life of the lighting.
Emergency flasher
T he emergency flasher makes other motorists
aware that you or your vehicle are in an emer­
gency situation .
Fig. 37 C ente r co nso le: em erg en cy flash er sw it ch
.. Press the switch ~ Q fig. 3 7 to turn the
emergency flashers on or off.
When the emergency flasher is on, all four
turn s ignals blink at the same time. The turn
signal indicator lights
11111 in the instru­
ment cluster, as well as the light in the emer­
gency flasher switch~ blink likewise. The
emergency flashers also work when the igni­
tion is turned off.
The emergency flashers will turn on automati­
cally if you are in an accident where the airbag
has deployed.
@ Tips
You should turn on the emergency flashers
when:
- you are the last vehicle standing in a traf­
fic jam so that any other vehicles coming
can see you, or when
- your vehicle has broken down or you are
in an emergency situation, or when
-your vehicle is being towed by a tow
truck or if you are towing another vehicle
behind you.
Adjusting the exterior lighting
The settings are adjusted in the MMI.

Tie-downs and cargo net
The cargo net* prevents small objects from
sliding .
Fig. 67 Location of th e tie -downs in the luggage com­
partment
Fig. 68 Lugg age compartment: cargo net•
.. To secure objects with the luggage com part·
ment net*, fold the tie-dow n bracket up­
ward
cc> fig. 67.
.. Insert the hooks on the luggage compart­
ment net* into the tie-downs ¢
fig. 68 .
.. Read and heed all WARNINGS ¢ page 132,
Stowing luggage.
In a collis ion, the laws of phys ics mean that
even smaller items that are loose in the vehi­
cle will turn into heavy missiles that can cause
serious injury. Items in the veh icle pick up ki­
netic energy which varies with the vehicle and
the weight of the item. Vehicle speed is the
most significant factor.
F or example, in a frontal coll is ion at a speed
of 30 mph (48 km/h), the forces acting on a
10- lb (5 kg) object are about
20 times the
normal weight of th e item. This means that
the weight of the item would suddenly be the
equivalent of about 200 lbs (90 kg). One can
easi ly imagine the injuries that an item of that
weight flying freely through the passenger
Seats and storage 65
compartment can cause in a collision at a
speed considered relatively low.
A WARNING
Weak, damaged or improper straps used
to secure items to tie-down s can fail dur­
ing hard braking or in a collision and cause
serious personal injury.
- Always use suitable retaining straps and
properly secure items to the tie-downs in
the luggage compartment to help pre­
vent items from shifting or flying for­
ward.
- Never attach a child seat tether strap to
a t ie-down .
- For strength-related reasons, the mount­
ing hooks can only be used to secure ob­
jects weigh ing up to 10 lb. (5 kg). Heavi­
er objects will not be adequately secured
- there is a risk of injury.
Pass-through with ski
sack
Pass-through with ski sack
App lies to vehicles : wi th ski sack
Long objects such as skis can be transported
in the ski sack* .
Fig. 69 Rear bench seat: opening the pass -through
Fig. 70 Sk i sack: secu ring with rea r seat safety belt

66 Seats and storage
Opening the trunk pass-through
.. Fold the center armrest in the rear forward
and out .
.. Pull the release handle ¢
fig. 69 and fold
down the cover of the pass -through in the
vehicle interior .
.. Open the rear lid .
.. Push the ski sack* through the opening from
the luggage compartment .
Securing the ski sack*
.. Insert the ski sack strap @¢ fig. 70 in the
center buck le @ .
.. Pull the safety belt taut on the free end of
the belt @.
A WARNING
-The ski sack is intended only for the
t ransportation of skis and other light ob­
jects . To reduce the risk of serious per­
sonal inj ury never t ransport heavy o r
pointed objects in the ski sack .
- When brak ing rapidly or during an acci­
dent the load could be displaced and
cause injury to occupants .
- Sharp edges on the load must be covered
for protection . Always fasten the belt
tightly around the sack and its contents
¢ fig. 70.
(D Tips
- Never stow the ski sack away when it is
still wet or damp (for example, snow
melting from skis). Allow it to dry com­
pletely before stowing it away.
- Position skis in the ski sack with the
pointed ends facing the front and ski
poles with the pointed ends facing the
rear.

Starting the engine
"'Press the brake pedal c::> _&..
"'Pr ess the !START ENGINE STOPI button
c::> fig. 77. The engi ne will start.
"' It is possible that there will be a slight delay
when starting the engine for diesel vehicles
in colder temperatures. Therefore, you must
hold the brake pedal down until the engine
starts. The indicator lamp
Ii illuminates
when the engine is preheated.
If the engine should not start immedi ately,
the starting process is automatically stopped
after a short time . Repeat starting procedure.
Start-Stop-System*:
Note the information on c::> page 79, Start­
Stop-System.
A WARNING
- Never allow the engine to run in confined
spaces -danger of asphyxiation .
- Never turn off the engine until the vehi­
cle has come to a complete stop.
- The brake booster and power steering
only work when the engine is running.
If
the engine is off, you have to use more
force when steering or braking. Because
you cannot steer and brake as you usual­
ly would, this could lead to crashes and
serious injuries.
-Avoid high engine rpm, full throttle and
heavy engine loads until the engine has
reached operating temperature - other­
wise you risk engine damage.
- The engine cannot be started by pushing
or towing the vehicle.
(D Tips
-After a cold engine is started, there may
be a brief period of increased noise be­
cause oil pressure must first build up in
the hydraulic valve adjusters. This is nor­ mal and not a cause for concern.
- If you leave the vehicle with the ignition
switched on, the ignition will switch off
On the road 75
after a certain period of time. Please
note that electrical equipment such as
exterior lights will switch off as well
when that happens.
Stopping the engine
"'Bring your vehicle to a complete stop.
"' Move the selector lever to the P or N posi ­
tion .
"'Press the
I STAR T ENGINE ST OP I button
c::> page 7 4, fig. 77.
Steering lock
The steer ing locks when you turn the engine
off using the
I STAR T ENGINE STOP I button
and open the driver's door. The locked steer­ ing helps prevent vehicle theft.
Emergency off
If necessary, the engine can be switched off
with the selector lever in the R or D/S posi ­
tion. The engine stops if you press the
I START ENGINE STOPI button at speeds below
6 mph (10 km/h).
A WARNING
-Never turn off the engine until the vehi­
cle has come to a complete stop.
- The brake booster and power steering
only work when the engine is running. If
the engine is off, you have to use more
force when steering or braking. Because
you cannot steer and brake as you usual­
ly would, this could lead to crashes and
serious injuries.
- For safety reasons, you should always
park your vehicle with the selector lever
in P. Otherwise, the vehicle could inad­
vertently roll away.
- 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 tempera­
ture rises as the result of a heat buildup
.
or if the engine is hot and the engine .,..

General information
Applies to vehicles: with side assist
®
©
Fig . 102 Dr iving situations
AUDI
Fig. 103 Rear of t he ve hicle: positio n of t he se nsors
Side assist functions at speeds above approx i­
mately 19 mph (30 km/h).
@ Vehicl es th at ar e approaching
In certain cases, a vehicle will be classified as
cr itical for a lane change even if it is still
somewhat far away. The faster a vehicle ap­
p roaches, the sooner the display in the exteri­
or m irror will t urn on.
@ V ehicles traveling with you
Vehicles traveling w ith you are indicated in the
exterior m irror if they are classified as cr itical
for a lane change. All vehicles detec ted by
side assist are indicated by the time they en­
ter your "blind spot", at the latest.
Audi side assist 9 7
© Vehicle s left behind
If you s low ly pass a vehi cle that s ide assist has
detected (the difference in speed between the
vehicle and you r vehicle is less than 9 mph or
15 km/h), the display in the exterior mirror
turns on as soon as the vehicle enters your blind spot.
The disp lay will not t urn on if you quickly pass
a vehicle that side assist has detected (the dif­
ference in speed between the vehicle and your
vehicle is greater than 9 mph or 15 km/h).
Functi onal limitation s
The radar sensors are designed to detect the
left and right adjacent lanes when the road
lanes are the normal width. In certain situa­
tions, the d isp lay in the exterior mirror may
turn on even though there is no veh icle locat­
ed in the area that is cr itical for a lane change.
For example:
- if the lanes are narrow or if your are dr iving
on the edge of your lane.
If this is the case,
the system may have detected the vehicle in
another lane that is
not adjacent to your
current lane .
- if you a re driving through a curve. Side assist
may react to a vehicle that is one lane ove r
from the adjacent lane.
- if side assist reacts to other objects (such as
high or d isp laced guard rails) .
- In poor weather conditions. The side assist
functions are l imited .
Do not cover the radar sensors
c> fig. 103 with
stickers, depos its, bicycle wheels or other ob­
jects, because this will affect the funct ion. Do
not use s ide ass ist when towing a trailer. For
i nformation on cleaning, refer to
c> page 209 .
_&. WARNING
-Always pay attention to traffic and to t he
area around your ve hicl e. S ide assist can­
not replace a driver's attention. The driv­
er a lone is always responsible for lane
changes and similar driving mane uvers.
