In certain cases, a vehicle will be classified as
critical for a lane change even if it is still some­
what far away. The faste r a veh icle approaches,
t he sooner the display in the exterio r mirror w ill
turn on.
@ Vehicles traveling with you
Vehicles traveli ng with you are ind icated in the
exte rior mi rror if they are classified as critical for
a lane change. All vehicles detected by side assist
Assistance systems
are indicated by the time they ente r your "blind
spot", at the latest.
© Vehicles you are passing
If you s low ly pass a vehi cle that side assist has
de tected (the difference in speed between the
vehicle and your vehicle is less than approximate­
ly 9 mph (15 km/h)), the disp lay in the exterior
mirror turns on as soon as the vehicle enters your
blind spot.
T he display w ill not turn on if you quickly pass a
vehicle that side assist has detected (the differ­ ence in speed is greater than approximate ly 9
mph (15 km/h)) .
Functional limitations
The radar sensors are designed to detect the left
and right adjacent lanes when the road lanes are
the normal width. In some situations, the display
in the exterior mirror may turn on even though
there is no veh icle located in the area that is criti­
cal for a lane change. For example :
- If the lanes are narrow or if your are driving on
the edge of your lane. If this is the case, the
system may have detected a vehicle in another lane that is
not adjacent to your current lane .
- If you are driving through a curve . Side assist
may react to a vehicle that is in the same lane
or one lane over from the adjacent lane .
- If side assist reacts to other objects (such as
roadside structures like guard rails).
- In poor weather conditions. The side assist
functions are limited.
Do not cover the radar sensors
c:> fig. 122 with
stickers, deposits, bicycle wheels or other ob­
jects, because th is will impair the function . Do
not use s ide assist when towing a trai ler. For in ­
formation on cleaning, see
c:> page 354.
A WARNING
-- Always pay attention to traffic and to the
area around your vehicle . S ide assist cannot
replace a driver's attention. The driver alone
is always responsible for lane changes and
-
similar driving maneuvers . IJI,

system warns the passengers of a possible colli­
sion when opening the door . Within the limits of
the system, the system monitors the areas be­
hind and next to the vehicle using the radar sen­
sors
~ page 127, fig. 122 . Moving objects that
are approaching from behind, such as cars, are
detected
~ fig. 123.
When you open the door, the warning strip on
the affected door blinks ¢
fig. 124 if another
road us er is detected and the situation is classi­
f ied as critical. The display in the exterior mirror
on the affected s ide flashes at the same time . If
the door is already open and another road user is
detected and the situation is classified as critical,
then the corresponding displays turn on.
A WARNING
-A lways pay attention to traffic and to the
area around your vehicle. The exit warning
system does not replace the attention of the
passengers. The vehicle passengers are al-

:E Air suspension*
The air suspension* is an electronically-control­
l ed air suspens ion and damping sys tem . The ad­
justment depends on the driving mode selected, steer ing movements, the driver's braking and ac­
celeration, and as the road surface, vehicle speed
and load. The vehicle ground clearance depends
on the mode selected and the speed .
The ground clearance increases s ignificantly
when the vehicle is in the
Allroad mode . At
speeds from approximately 50 mph (80 km/h) to
75 mph (120 km/h), the ground clearance re­
duces in stages. When the speed decreases, the
ground clearance increases again automat ically .
The ground clearance is the lowest in
Dynamic
mode.
Steering
The power steering adapts. Ind irect steer ing that
moves easily as in
Comfort mode is especially
suited to long drives on highways. The
Dynamic
mode provides sporty, direct steering.
All-wheel steering*
All-wheel steer ing increases driving comfort by
providing addit ional steering ability at the rear
axle . Steer ing in the opposite d irection at low
speeds decreases the turning rad ius. Steering in
the same d irect io n at high speeds improves the
response time while increasing driving stability at
the same time .
Sport differential*
As a component of the all wheel drive system
(quattro)
~ page 152, the sport diffe rential dis­
tributes the dr iv ing power to the rear axle de­
pending on the situation. The distribution of
power varies depending on the selected mode
from moderate
( Comfort ) to sporty (Dynamic ).
The goal is a high level of agility and ability to ac ­
celerate on curves . The vehicle is very responsive
to steering.
Adaptive cruise control (ACC)*
The behavior when accelerating can be adjusted
from comfortab le to sporty, depending on the
drive select mode. Adaptive cruise control also
Assistance systems
responds to the driving behavior of the vehicle
ahead in a more conservative or sporty manner.
Engine sound*
T he eng ine sound adapts to the current mode
and can be subtle to sporty .
(D Note
Applies to: vehicles wi th air suspensio n
-Make sure there is enough clearance above
and below the vehicle when parking. The
height of the ve hicle (gro und clearance) can
change once it is parked due to temperature
fluctuations, changes to the load conditions
and changes to the dr iving modes.
- 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 c ircumference.
Sec uring the vehicle at the axle compo­
nents, suspension struts o r towing eyes is
not permitted because the pressure in the
air suspens ion struts can change during
transport. The vehicle may not be secured
sufficiently if this happens.

General information
A ppl ies to: ve hicles w ith a rea r parking sys te m /pa rking sys ­
tem p lus/rearv iew camera/peripheral ca meras
Depending on your vehicle's equipment , various
parking aids will help you when parking and ma­
neuvering.
The
rear parking system is an audible parking aid
that warns you of obstacles
behind the vehicle
¢ page 139.
The
parking system plus assists you when park ­
ing by audibly and visually indicating objects de­
tected
in front of and behind the veh icle
¢ page 139.
The
rearview camera shows the area behind the
vehicle in the Infotainment system display . The
lines in the rearview camera image help you to
park or maneuver
¢ page 140. The parking sys­
tem plus functions are also available
¢ page 139.
The
peripheral cameras give various views to
help you when parking or maneuvering
¢ page 143. The parking system plus functions
are also available
¢page 139.
A WARNING i-==
- Always look for traffic and check the area
around your vehicle by looking at it directly
as well. The parking system cannot replace
the driver's attention. The driver is always
responsible when entering or leaving a park­
ing space and during similar maneuvers.
-
- Please note that some surfaces , such as
clothing, are not detected by the system .
- Sensors and cameras have blind spots in
which people and objects cannot be detect­
ed . Be especially cautious of small children
and animals .
- Always keep your eyes on the vehicle's sur ­
roundings, using the rearview mirror as
well.
- The sensors can be displaced by impacts or
damage to the radiator grille, bumper,
wheel housing and the underbody. The park­ ing system may be impa ired as a result.
138
Have an authorized Audi dealer or author­
ized Audi Service Facility check their func­
tion.
(D Note
- Some objects are not detected or displayed
by the system under certain circumstances:
- objects such as barrier chains, trailer draw
bars, vertical poles or fences
- objects above the sensors such as wall ex ­
tensions
- objects with certain surfaces or structures
such as chain link fences or powder snow
- If you continue driving closer to a low ob­
ject, it may disappear from the sensor
range. Note that you will no longer be
warned about this obstacle.
- Keep enough distance from the curb to re ­
duce the risk of damage to the rims.
{i) Tips
- The system may provide a warning even
though there are no obstacles in the cover ­
age area in some situations, such as:
- certain road surfaces or when there is tall
grass
- external ultrasonic sources such as from
cleaning vehicles
- in heavy rain, snow, or thick vehicle ex­
haust
- We recommend that you practice parking in
a traffic-free location or parking lot to be­
come familiar with the system . When doing
this, there should be good light and weath­
er conditions.
- You can change the volume of the signals
and the display ¢
page 146.
- Please refer to the instructions for towing a
trailer located in
¢page 147.
- What appears in the infotainment display is
somewhat time-delayed.
- Th e sensors must be kept clean and free of
snow and ice for the parking aid to operate .

Wheel bolts and rims
Wheel bolts
Wheel bolts must be clean and loosen/t ighten
easi ly .
Rims
Rims with a bolted rim ring* or w ith bolted whee l
covers* consist of mu ltiple pieces . These compo­
nents we re bolted together using special bolts
348
and a spec ia l proced ure. Yo u must no t repair or
disassemb le them
c:::> .&. .
A WARNING
Wheel bo lts that are tightened or repaired in­
correct ly can become loose and resu lt in loss
of vehicle contro l, wh ich increases the risk of
an accident. For the correct tighten ing spec ifi ­
cation, see
c:::> page 365, Finishing.
- Always keep the wheel bolts and the
threads in the wheel h ub clean and free of
grease .
- Only use wheel bolts that fit the rim.
- Always have damaged rims repaired by an
author ized Audi dealer or authorized Audi
Serv ice Facility . Never repa ir or disassemb le
rims yourself, because this increases the risk
of an accident.
Winter tires
Winter tires significant ly improve the vehicle's
hand ling when dr iv ing in winter conditions. Be­
cause of their construct ion (w idth, compound,
tread pattern), summer tires provide less t rac ­
tion on ice and snow .
.,. Use win ter tires on all four wheels.
.,. On ly use winter tires that a re approved for your
veh icle.
.,. Please note that the maximum permitted
speed may be lower with winter tires
c::> &_ . An
authorized Audi dealer or authorized Audi Serv­
ice Facility can inform you about the maximum
permitted speed for your tires .
.,. Check the tire p ressure after installing wheels
c::> page 343 .
The effectiveness of winter tires is reduced great­
ly when the tread is worn down to a depth of
0 .16 in (4 mm). The cha racteristics of winte r
t ir es a lso decrease g reatly as the t ire ages , re­
gard less of the rema ining t read.
.&_ WARNING
-
- Never d rive fas ter than the max imum pe r­
mitted speed for your tires . This could cause
the tires to heat up too much . This increases
~

Emergency assistance
-If a tire pressure of 29 psi (200 kPA) cannot
reached after inflating for 6 minutes, then
the tire is too severely damaged. Do not
continue driving.
- If the tire cannot be repaired with the tire
sealant, see an authorized Audi dealer or au­
thorized Audi Service Facility for ass istance.
(D} Tips
Do not operate the compressor for more than
six minutes continuously, or it can overheat.
Once the compressor has cooled, you can con­
tinue to use it .
Completing
"' Adhere the sticke r that says "max . SO mph
(max. 80 km/h)" that is provided w ith the tir e
mobility kit within the driver's fie ld of vision.
"'S top the vehicle after driving for about 10 mi­
nutes and check the tire pressure .
"' If the tire pressure is lower than 19 psi (130
kPA), then the tire is too severely damaged. Do
not continue driving.
A WARNING
Pay attention to the following after repairing
the tire :
- Do not drive faster than SO mph (80 km/h).
- Avoid hard acceleration, braking sharply, and fast cornering.
- The vehicle may become more difficult to
control.
- If the tire is too severely damaged, see an
authorized Audi dealer or authorized Aud i
Service Facility for assistance .
@ For the sake of the environment
You can give the used tire sealant bottle to an
authorized Audi dealer or authorized Audi
Service Facility for disposal.
@ Tips
Remember to obtain a new bottle of sealant
from an authorized Audi dea ler or authorized
Audi Service Facility after repairing a tire.

Emergency situations
Emergency situations
General
This chapter is intended for trained emergency crews and working personnel who have the nec­
essary tools and equipment to perform these
operations.
Starting by pushing or
towing
(D Note
Vehicles with an automatic transmission
cannot be started by pushing or towing.
Starting with jumper
cables
If necessary, the engine con be started by con­
necting it to the battery of another vehicle.
If the engine should fail to start because of a dis­
charged or weak battery, the battery can be con­
nected to the battery of
another vehicle, using a
pair of jumper cables to start the engine.
Jumper cables
Use only jumper cables of sufficiently large cross
section
to carry the starter current safely. Refer
to the manufacturer's specifications.
Use only jumper cables with
insulated terminal
clamps which are distinctly marked :
plus(+) cable in most cases colored red
minus(-) cable
in most cases colored black.
A WARNING
Batteries contain electricity, acid, and gas.
Any of these can cause very serious or fatal in­
jury. Follow the instructions below for
safe
handling of your vehicle's battery.
-Always shield your eyes and avoid leaning
over the battery whenever possible.
-A dead battery can freeze at temperatures
around 32 °F (0 °C) . If the vehicle battery is
frozen, you must thaw it before connecting
the jump start cables.
If you do not, this in-
372
creases the risk of an explosion and chemi­
cal burns. After jump starting the vehicle,
drive to an authorized Audi dealer or author­
ized Audi Service Facility immediately to
have the vehicle battery checked.
- Do not allow battery acid to contact eyes or
skin . Flush any contacted area with water
immediately.
- Improper use of a booster battery to start a
vehicle may cause an explosion .
- Vehicle batteries generate explosive gases.
Keep sparks, flame and lighted cigarettes
away from batteries.
- Do not try to jump start any vehicle with a
low acid level in the battery.
- The voltage of the booster battery must also
have a 12-Volt rating. The capacity (Ah) of
the booster battery should not be lower
than that of the discharged battery. Use of
batteries of different voltage or substantial­
ly different "Ah" rating may cause an explo­
sion and personal injury.
- Never charge a frozen battery. Gas trapped
in the ice may cause an explosion.
- Never charge or use a battery that has been
frozen. The battery case may have be weak­
ened.
- Use of batteries of different voltage or sub­
stantially different capacity (Ah) rating may
cause an explosion and injury. The capacity (Ah) of the booster battery should not be
lower than that of the discharged battery.
- Before you check anything in the engine
compartment, always read and heed all
WARNINGS
r=:> poge 322.
([) Note
-Applying a higher voltage booster battery
will cause expensive damage to sensitive electronic components, such as control
units, relays, radio, etc.
- There must be no electrical contact between
the vehicles as otherwise current could al­
ready start to flow as soon as the positive
(+) terminals are connected.

Emergency situations
-When connecting jumper cables, make sure
that they cannot get caught in any moving
parts in the engine compartment.
- Do not bend over the batteries -danger of
chemical burns!
- The battery cell locking screws must be
tightened securely.
- Before you check anything in the engine
compartment, always read and heed all
WARNINGS
i=> page 322.
(D Note
Improper hook-up of jumper cables can ruin
the generator.
- Always connect POSITIVE(+) to POSITIVE
(+), and NEGATIVE(-) to NEGATIVE(-)
ground post of the battery manager control
unit.
- Check that all screw p lugs on the battery
cells are screwed in firmly. If not, tighten
plugs prior to connect ing clamp on negative
battery terminal.
- Please note that the procedure for connect ­
i ng a jumper cable as described above ap­
plies specifically to the case of your vehicle
being jump started . When you are giving a
ju mp start to another vehicle, do
