Highway light function*
(vehicles with LED
headlights) -this function adapts the lighting
for highway driving based on vehicle speed.
.&_ 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 §,0
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
the headlights so that you can see ahead
and so that others can see your car from
the back .
(D Note
The rear fog lights should only be turned
on in accordance with traffic regulation, as
the lights are bright for following traffic.
(D Tips
- In the event of a light sensor malfunc­
tion, the driver is notified in the instru­
ment cluster display
q page 21 .
-You will hear a warning tone if you open
the driver door when the exterior lights
are switched on.
- Please observe legal regulations when
using the lighting systems described .
Emergency flasher
The emergency flasher makes other motorists
aware that you or your vehicle ore in on emer­
gency situation .
Fig. 36 Ce nte r co nso le: em erg en cy flash er sw itch
.,. Press the switch~ c:> fig. 36 to turn the
emergency flashers on or off.
When the emergency flasher is on, all four
turn signals blink at the same time. The turn
signal indicator lights¢¢ in the instrument
cluster, as well as the light in the emergency
flasher switch
~ blink likewise.
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.

Luggage compartment
Tie-downs and luggage compartment net
The Luggage compartment net prevents small
objects from sliding .

compartment
Fig. 64 Luggage compartment net unhooked
~ To secure objects with the luggage compart­
ment net*, fold the tie-down bracket up­
ward ¢
fig. 63 .
~ Insert the hooks on the luggage compart­
ment net* into the tie-downs ¢
fig. 64.
~ Read and heed all WARNINGS¢ page 133,
Stowing Luggage.
In a coll is 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 vehicle 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 collis ion at a speed
of 30 mph (48 km/h), the forces acting on a
10-lb (4.5 kg) object are about
20 times the
normal weight of the item. This means that
the we ight of the item would suddenly be the
Seats and storage 65
equivalent of about 200 lbs (90 kg). One can
easily imagine the injuries that an item of that
weight flying freely through the passenger
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-downs can fail dur­ ing hard braking or in a collision and cause
serious personal injury.
-Al ways use su itable 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 tie-down.
- For strength-related reasons, the mount­
ing hooks can only be used to secure ob­
jects weighing up to 10 lb. (5 kg) . Heavi­
er objects will not be adequately secured
- there is a risk of injury.

A WARNING
-The ski sack is intended only for the
transportation of skis and other light ob­
jects. To reduce the risk of serious per­
sonal injury, never transport heavy or pointed objects in the ski sack.
- When brak ing rapidly or during an acci­
dent, the load could be displaced and
cause i njury to occupants.
- Sharp edges on the load must be covered
for protect ion. Always fasten the belt
ti ghtly around the sack and its contents
~fig. 68.
-For safety reasons, do not t ransport
more than two pairs of skis in the ski
sack .
- You must secure the ski sack with the
strap after loading.
- Make sure all objects tha t you are trans­
porting in the pass-th rough a re secured.
Otherwise they cou ld slide around during
s u dden braking maneuvers and cause in­
jury.
(D Tips
- Never stow the sk i sack away when it is
still wet or damp ( for example, snow
melting from skis). Allow it to dry com­
plete ly before stowing it away.
- Position skis in the ski sack w ith the
pointed ends facing the front and ski
po les w ith the pointed ends facing the
rear.

(D Note
-Avoid hig h engine rpm, fu ll throttle and
heavy engine loads unti l the engine has
reached operating temperat ure -other­
wise you risk eng ine damage.
- The engine cannot be started by pushing
or towing the vehicle.
- If the engine has been under heavy load
for an extended period, heat b uilds up in
the engine compartment after the en­
gine is switched off - there is a risk of
damaging the engine . Allow the eng ine
to run at idle for about 2 minutes before
switching it off.
@ Tips
If you open the driver's door with the igni­
tion on, a buzzer sounds and the message
Igniti on is on appears in the instrument
cluster display. Sw itch the ignition off .

tions . The engine stops if you press the
I S TAR T ENGINE ST OP ! button at speeds be low
6 mph (10 km/h).
A WARNING
- Never turn off the eng ine unti l the vehi­
cle has come to a complete stop.
- The brake booster and power steer ing
only work when the engine is runn ing .
If
the engine is off, you have to use more
force when steering or braking. Because
you cannot steer and brake as you usua l­
ly wo uld, this could lead to crashes and
serious injuries. -
For safety reasons, you should a lways
park your vehicle w ith the selector lever
in P . Otherwise, the vehicle could inad­
vertently roll away .
- After the engine has been switched off,
the radiator fan can cont inue to run for
up to 10 minutes -even with the ignition
sw itched off. It can also sw itch on again
after some time if the coolant tempera­
ture rises as the result ofa heat bu ildup
or if the engine is hot and the engine
compartment is additionally heated by
the sun's rays .
(D Note
Do not stop the eng ine immedia tely after

104 Audi side assist
right of your travel lane, depending on wheth­
er you drive in the center of your lane or closer
to the edge.
If you drive in narrow lanes, s ide ass ist's de­
tection a rea may a lso include other lanes -es­
pecia lly if you tend to drive on the edge of
your lane¢
fig. 108. Under these cond it ions ,
vehicles can also be detected that are two lanes away, and side assist then could switch
between the informat ional and warn ing stage
signals .
When driving in very w ide lanes, vehicles in
the adjacent lane may not be detected be­
cause they are not inside the detection area.
Notes
Messages in instrument cluster display
Applies to vehicles: with side assis t
If side assist turns off automatically, the indi­
cator light on the button wi ll go out and you
will see a message in the instrument cluster
d isplay:
Audi side assist: not available. sensors
blocked
The side assist sensors are built into the rear
bumper on the left and right (not visible on
the outside)
¢ page 98, fig. 99 . To ensure that
you do not adversely affect the way side assist
functions, foreign objects (such as stickers or
b icycle racks) should not be attached to the
a rea on the rear bumper where the sensors
are located. If side assist functions are ad­
ve rsely affected, you will see this message in
the instrument cluster display. Remove any ­
thing that may be blocking the sensors .
If no vehicl e is detected for a longer period of
time while driving, side assist will also switc h
off a utomatica lly.
Audi side assist currently not available
If there is a temporary problem (such as the
ve hicl e's battery charge being low), s ide ass ist
cannot be activated tempo rari ly.
Audi side assist: system fault
Have the system checked by an authorized Au­
di dealer or qualified workshop.
Audi side assist: not available when
towing
The radar senso r's view is limited when tow ­
ing a trai le r. F or vehicles with a factory instal­
l ed towing hitch or a trailer hitch that was in­
sta lled later according to factory specifica­
tions, side assist is automatically deactivated as soon as the electrical connection to the
trailer's electrical socket is made, and this sta­
tus message appears in the instrument clus ­
ter display . Deactivation cannot be guaran­
teed when using a retrofitted towing hitch
that was
not installed acco rding to facto ry
specifications.
Safety tips
Appl ies to vehicles : wi th side assist
The side assist detection may be limited when
driv ing aro und narrow street corners, on hilly
streets, and under poor weather cond itions.
It is possible that the radar sensors may also
detect other objects, such as high or stag­
gered guardrails .
Side assist does not measure actual lane
width. The system assumes a fixed lane width.
Detection in the left and right lanes is based
o n this ass umed lane width . When driving on
narrow roads or when driv ing to the left or
right of the center of a trave l lane, it is poss i­
ble that vehicles will be detected that are
not
in the lane next to the lane you are using.
A WARNING
- Improper reliance on the side assist sys­
tem can cause collis ions and serious per­
sonal injury:
- Never rely on ly on side assist when
changing lanes .
- Always check rear view mirrors to make
sure that it is sa fe to change lanes.
- Side assist cannot detect all vehicles un-
der all conditions- danger of accident! ..,.
