Audi active Lane assist
Description
Applies to: veh icles w ith Audi active lane assist
Active lane assist (lane departure warning) de­
tects lane ma rker lines withi n the l imits of the
system using a camera in the windshield. If you
are approaching a detected lane marker line and it appears likely that you will leave the lane, the
system will warn you w ith corrective stee ring .
You can override this steering at any time . If you
112
pass over a line, the steering wheel will vibrate
lightly. In order for this warning vibration to oc­
cur, it must first be switched on in the Infotain­
ment system. Active lane ass ist is ready for oper­
a tion when the lane marker line is detected on at
least one side of the vehicle .
T he system is des igned for driving on express­
ways and highways and therefore on ly activates
a t speeds above approximately 40 mph (65 km/
h) .
Applies to vehicles with s ide ass ist*: if you acti­
vate a turn signa l when active lane assist is ready
a nd it classifies a lane change as critical bec ause
of veh icles traveling a longside you or approach ­
i ng you, there will be noticeable corrective steer­
i ng shortly before you leave the lane. This will at­
tempt to keep your vehicle in the lane.
Applies to vehicles without side assist* : the sys ­
tem does not warn when it is ready if you act ivate
the turn signal before crossing the lane marker
lin e. In this case, it assumes that you are chang­
in g lanes intent ionally.
Applies to vehicles with adaptive cruise contro l*:
there is no corrective steer ing or warnings if the
system recognizes a distinct passing maneuver.
If the conditions are met, congestion assist
switches on at speeds under approximately
40 mph (65 km/h)
¢page 104.
_& WARNING
-The system warns the driver that the vehicle
is leaving the lane using correct ive steering.
The driver is always responsible for keeping
the vehicle within the lane.
- The system can help you keep the vehicle in
the lane, but it does not drive by itself. Al­
ways keep your hands on the steering
wheel.
- 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. Correc­
tive steering can only take place on the side
of the vehicle where lane marker lines are
detected.

are indicated, at the latest, by the time they en­
ter your "blind spot".
© Vehicles you are passing
If you slowly pass a vehicle that side assist has
detected (the difference in speed between the
veh icle and your vehicle is less than approximate­
ly 9 mph (15 km/h)), the display in the exterior
mirror turns on as soon as the vehicle enters your
blind spot.
The display will not turn on if you quickly pass a
vehicle that side assist has detected (the differ­
ence in speed is greater than approximately 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 vehicle 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 ¢
fig. 112 with
stickers, deposits, bicycle racks or other objects,
because this will impair their function. Do not
use side assist when towing a trailer. For infor­
mation on cleaning, refer to¢
page 33 7.
A WARNING
- Always pay attention to traffic and to the
area around your vehicle. Side assist cannot
replace a driver's attention. The driver alone
is a lways responsible for lane changes and
similar driving maneuvers.
Assist
-In some situations, the system may not
function or its function may be limited. For
example:
- If vehicles are approaching or being left
behind very quickly. The display may not
turn on in time.
- In poor weather conditions such as heavy
rain, snow or heavy m ist.
- On very wide lanes, in tight curves, or if
there is a rise in the road surface. Vehicles
in the adjacent lane may not be detected
because they are outside of the sensor
range.
(D Note
The sensors can be displaced by impacts or
damage to the bumper, wheel housing and
underbody. This can adversely affect the sys­
tem. Have an authorized Audi dealer or au­
thorized Audi Service Facility check their func­
tion.
(D Tips
If the window glass in the driver's door or
front passenger's door has been tinted, the
display in the exterior mirror may be incor­
rect.
Switching on and off
App lies to : vehicles wi th Audi sid e ass ist

A WARNING
- 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 impaired as a result.
Have an authorized Audi dealer or author-
124
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 th is obstacle .
- Keep enough distance from the curb to
avoid damage to the rims.
(D 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 131.
-Please refer to the instructions for trailer
towing in
¢page 132.
- What appears in the infotainment display is
somewhat time-delayed.
- Th e sensors must be kept clean and free of
snow and ice for park assist to operate.

Determining correct load
limit
Use the example below to calcu­
late the total weight of the pas­
sengers and luggage or other
things that you plan to transport
so that you can ma ke sure that
your vehicle will not be overload­ ed .
Steps for Determining Correct
Load Limit
1 . Locate the statement "THE
COMBINED WEIGHT OF OCCU­ PANTS AND CARGO SHOULD
NEVER EXCEED XXX KG OR XXX
LBS"on your vehicle 's pla card
(tire inflation pre ssure l abel)
¢ page 327, fig. 256.
2 . Determine the combined
weight of the drive r and pas­
s engers that will be riding in
your vehicle.
3 . Subtra ct the combined weight
of the driver and passengers
from
" XXX" kilograms or "XXX"
pounds shown on the stick­
er ¢
page 32 7, fig . 256.
4. The re sulting figure equals the
available amount of cargo and
luggage load capacity. For ex-
; ample, if the
"XXX" amount
N
~ equals 1400 lbs. and there will 0 0
3 Wheels
be five 1 SO lbs. pa ssengers in
your vehicle, the amount of available cargo and luggage load capacity i s 650 lb s.
(1400-750 (5 X 150) = 650
lbs.)
5. Determin e the combined
weight of luggage and cargo
being loaded on the vehicle.
That weight may not safely ex­
ceed the available cargo and luggage load capa city cal culat­
ed in Step

If your vehi cle will be towing a
trailer, load from your trailer
will be transferred to your ve­
hicle. Con sult thi s manual to
determine how this reduces
the available cargo and lug­ gage load capacity of your vehi­
cle.

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
CD Note
Vehicles with an automatic transmission
cannot be started by pushing or towing.
Starting with jumper
cables
If necessary, the engin e 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 discharged battery can freeze at tempera­
tures just below 32 °F (0 °C). Before con­
necting a jumper cable, you must thaw the
356
frozen battery completely, otherwise it could explode.
- 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
~page 304.
CD 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.
@ Tips
The discharged battery must be properly con-
nected to the vehicle's electrical system. .,..

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
c> page 304.
(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
not con­
nect the negative (-) cable to the negative
(-) terminal on the discharged batte ry @
c> fig. 2 75. Instead, securely connect the
negative( -) cab le to either a solid metal
component that is firm ly bolted to the en­
gine block or to the engine block itself. If
the battery that is being charged does not
vent to the outside, escap ing battery gas
could ignite and explode!
