Backing up is difficult and requires pract ice .
Backing up with a trailer generally requires steer­
i ng action oppos ite to that when backing up your
ve hicle w ithout a trailer.
M ain tain a greater d istance between your vehicle
and the one in front of you. Yo u wi ll nee d more
room to stop. To compensate fo r th e tra iler, yo u
will need a larger than no rmal turn ing rad ius.
When pass ing, remembe r th at you ca nnot accel ­
erate as fast as you norma lly wou ld because of
the added load. Make s ure yo u have eno ugh room

The rear cross -traffic assis t can warn the drive r of
a po tential collis ion with approaching cross -traf­
f ic when driv ing i n reverse . Within its limits, the
system monitors the areas beh ind and n ext to
the vehicle using the radar sensors when leaving
a park ing space

If the system detects cr itical cross traffic when
ba cking out of a parking space, it will react as fol­
lows :
-Visual indicator : an indicator appea rs in the In­
fotainment system display with a red arrow
symbol. The arrow points in the direction from
which the object is approach ing
c::> fig. 134 .
-Audible warning signal : a continuous tone may
sound as an additional indicator when driving in reverse .

-Please note that the rear cross-traff ic assist
may activate the brakes unexpected ly. Se­
cure any cargo that you are transporting to
reduce the ris k of damage or injury .
-An add itiona l brake activation may be trig­
ge red w ith in 20 seconds after an automatic
brake activation .
-If there is an acoust ic warning signal from
the rea r cross-traffic assist, then the park­
ing system may no t warn you of detected
obs tacles under certain circumstances.

_& WARNING
- T urn the engine off.
- Switch the ign ition off .
- Set the parking brake .
- Shift the gearshift lever to neutral in vehicles with a manual transm ission and se­
lect the P selector lever posit ion in vehicles
with an automatic transmission .
- Let the engine coo l down.
- Never open the hood when there is steam or coolant escaping from the eng ine compart­
ment, because there is a risk that you cou ld
be burned . Wait until no steam or coolant is
escaping.
- Keep children away from the engine com­
partment.
- Never spill flu ids on a hot engine. These flu­
ids (such as the anti-freezing agent con­
tained in the coolant) can ignite.
- Avoid sho rt circu its in the e lectrical system.
- When working in the engine compartment,
remember that the radiator fan can sw itch
on even if the ign ition is switched off , which
increases the risk of inj ury .
- Never open the cap on the coolant expan­
sion tank when the eng ine is warm. The
cooling system is under press ure.
- T o protect your face, hands, and arms from
hot steam or coolant, cover the cap with a
large cloth when opening.
- Do not remove the eng ine cover under any
c ircumstances . This increases the risk of
burns .
Check ing and Filling
-If tests need to be performed with the en­
gine running, there is add itiona l danger due
to mov ing components (such as the ribbed
belt, alternator and radiator fan) and from
the high-voltage ignition system.
-Do not under any circumstances activate the
throttle inadvertently (for example, by hand
from the engine compartment) if the veh i­
cle is stat ionary but the eng ine is running
and a gea r is engaged. Otherwise, the veh i­
cle will start to move immed iate ly and this
could result in an accident.
- Pay attent ion to the following warn ings
when wor k on the fue l system is required :
- Do not smoke.
- Never work near open flames.
-Always have a working fi re extinguisher
nearby.
-All work on the battery or electrical system in your vehicle can result in injuries, chemi­
cal burns, accidents or burns. Because of
this, all work must be performed
o nly by an
author iz ed Audi dealer or author iz ed Audi
Serv ice Facility.
-To reduce the r isk of electric shock and in­
jury, never touch the following components
when the engine is runn ing or is being start­
ed:
- Ign ition cable
- Other components in the e lectronic high-
vo ltage ign ition system
-I f you must check or perform wo rk on the
engine wh ile it is running:
-First, set the parking brake and and move
the gearshift lever to neutral (for manual
transm issions) or select the P selector lev­
er position (for automatic transm iss ions).
- Always proceed w ith extreme caution so
that clothing, jewelry or long hair do not become caught in the radiator fan, fan
belt or other moving components or do
not come into contact with hot compo­
nents. Tie bac k long hair befo re beginning
work and do not wear clothing that can hang down into the engine.
-Lim it your exposure to exhaust and chemi­
cals to as short a time as possible
