towing AUDI Q3 2019 User Guide

Trailer towing

Tongue weight
The maximum permitted tongue weight of the
trailer drawbar on the trailer hitch ball head may
not be exceeded.
If the tongue weight is too low, this affects the
trailer's handling. For driving safety, we recom-
mend to always utilize the maximum permitted
tongue weight, but not exceed it. You can reach
it, for example, by distributing the cargo in the
trailer correctly.
You can determine the tongue weight using a
tongue weight scale, a bathroom scale, or a pub-
lic weigh station, for example.
The permitted tongue weight of your vehicle can
be found in the vehicle documentation or in
=> page 264.
Load distribution
Poor cargo load and distribution can negatively
impact vehicle handling. Load the trailer based
on the following criteria as much as possible:
— Store objects preferably in the vehicle luggage
compartment. The vehicle should always carry
the heaviest possible load and the trailer
should have the lightest possible load.
— Distribute the load in the trailer so that the
heavy objects are as close to the axle as possi-
ble.
— Secure objects from sliding out of place.
— Utilize the maximum permitted tongue weight
if possible.
Tires
Set the tire pressure on your vehicle for a “full
load”; see the tire pressure sticker > page 226. If
necessary, also adjust the tire pressure on the
trailer according to the manufacturer's recom-
mendation.
Winter tires should be mounted on the vehicle
and on the trailer during winter temperatures.
Outside mirrors
If you cannot see the traffic behind the trailer
with the standard exterior mirrors, then you
must attach additional exterior mirrors. Adjust
102
them so you have a sufficient visibility behind
you.
Exterior lighting
Follow the legal regulations for lighting on your
trailer that are applicable in the country where
you are operating the vehicle. Contact an author-
ized Audi dealer or authorized Audi Service Facili-
ty for more information.
Before starting to drive, check all lighting equip-
ment on the hitched trailer.
The headlight range control adjusts automatical-
ly to the light range of the headlights.
Safety chains
Make sure the safety chains are correctly applied
when pulling a trailer. The chains should hang
enough so that the trailer can drive around
curves. However, they must not touch the
ground.
@) Note
Attachments retrofitted on the vehicle may
cause damage, especially on the trailer hitch
ball head. In cases of damage, have the func-
tion checked by an authorized Audi dealer or
authorized Audi Service Facility.
G) Tips
— Use chocks when parking on inclines if the
trailer is loaded.
—We recommend also having the vehicle in-
spected between the inspection intervals if
you are towing a trailer frequently.
— Avoid driving with a trailer during the vehi-
cle break-in period.
Driving with a trailer
Driving with a trailer requires extra caution.
Speed
Adhere to the legal speed limits. Follow the legal
regulations that are applicable in the country
where you are operating the vehicle.

83A012721BA
Trailer towing

As the speed increases, the driving stability of
the trailer decreases. Therefore you should not
exceed the maximum legal speed limit when
there are unfavorable road, weather and/or wind
conditions. This especially applies when driving
downhill.
Hill
When transitioning to hills, trailers may tilt or
sway sooner than when driving on a level surface.
If small swaying movements have already occur-
red, you can stabilize the trailer by firmly braking
immediately. Never try to “straighten out” the
trailer by accelerating.
Downshift before driving on hills to utilize the en-
gine braking effect > A\.
Brakes
When using a trailer with overrun brakes, first
brake gently then quickly. This reduces the risk of
jerking while braking if the trailer wheels lock up.
Engine coolant temperature
Pay attention specifically to the coolant tempera-
ture display when there are high outside temper-
atures, and when driving on long inclines
=> page 13. Shift to a higher gear in a timely man-
ner.

ZA WARNING
Constant braking causes the brakes to over-
heat and substantially reduces braking per-
formance, increases braking distance or caus-

es complete failure of the brake system.

Assist systems

Assist systems
General information
Safety precautions

ZA WARNING
— As the driver, you are always completely re-
sponsible for all driving tasks. The assist
systems cannot replace the driver's atten-
tion. Give your full attention to driving the
vehicle, and be ready to intervene in the
traffic situation at all times.
— Activate the assist systems only if the sur-
rounding conditions permit it. Always adapt
your driving style to the current visual,
weather, road, and traffic conditions.
— Loose objects can be thrown around the ve-
hicle interior during sudden driving or brak-
ing maneuvers, which increases the risk of
an accident. Store objects securely while
driving.
— For the assist systems to be able to react
correctly, the function of the sensors and
cameras must not be restricted. Note the in-
formation on sensors and cameras
=> page 105 or > page 106.

@ Tips
— Pay attention to applicable local regulations
relating to driving tasks, leaving space for
emergency vehicles, vehicle distance, speed,
parking location, wheel placement, etc. The
driver is always responsible for following
the laws that are applicable in the location
where the vehicle is being operated.
— You can cancel a steering or braking inter-
vention by the system, by braking or accel-
erating noticeably, steering, or deactivating
the respective assist system.
— Always check the assist systems settings be-
fore driving.
104
System limitations
ZA WARNING
— The use of an assist system cannot over-
come the natural laws of physics. A collision
cannot be prevented in certain circumstan-
ces.

— Warnings, messages, or indicator lights may
not be displayed or initiated on time or cor-
rectly, for example, if vehicles are approach-
ing very fast.
— Corrective interventions by the assist sys-
tems, such as steering or braking interven-
tions, may not be sufficient or they may not
occur. Always be ready to intervene.
G) Tips
— Due to the system limitations when detect-
ing the surrounding area, the systems may
warn or intervene unexpectedly or too late
in certain situations. The assist systems may
also interpret a driving maneuver incorrectly
and then warn the driver unexpectedly.


— The systems may not function as expected
in unusual driving situations, such as driving
offroad, on unpaved roads, on loose ground,
on inclines, or on grooves in the road.
— The systems may not function correctly in
unclear traffic situations, such as turning
lanes, exit ramps, construction zones, rises
or dips that obstruct visibility, intersections,
toll stations, or city traffic.
—In trailer mode, some assist systems may be
limited, may not react as usual, or may be
unavailable. Please refer to the instructions
for towing a trailer located in > page 101.
— If accessories have been mounted on the
steering wheel, the ability for the steering
systems to react may be limited.

Driver assistance

Warning stage
If the display in a mirror blinks brightly when you
activate a turn signal, side assist is warning you
about detected objects classified as critical.
Depending on the vehicle equipment and other
driver assistance systems, the display on the re-
spective mirror may also flash if you have not
turned on the turn signal: If you are approaching
a detected lane marker line and it appears you
will be leaving the lane, the display on the mirror
will warn you about detected vehicles that it has
classified as critical. You can also be warned with
corrective steering > page 119, Lane departure
warning.
Detection range
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 you 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).

ZA\ WARNING
— Follow the safety precautions and note the
limits of the assist systems, sensors, and
cameras > page 104.
— The display may not appear on time when
vehicles are approaching or being passed
very quickly.

@ Tips
— The system is not available when towing a
trailer. There is no guarantee the system
will switch off when using a retrofitted trail-
er hitch. Do not use these functions when
towing a trailer.
— For an explanation on conformity with the
FCC regulations in the United States and the
Industry Canada regulations, see

Parking and maneuvering



— Sensors and cameras have spots in which
the surrounding area cannot be detected.
Objects, animals, and people may only be
detected with limitations may not be detect-
ed at all. Always monitor the traffic and the
vehicle's surroundings directly and do not
become distracted.

@) Note
— Keep enough distance from the curb to
avoid damage to the rims.
— Applies to: vehicles with park assist: If you
park in short parking spaces using park as-
sist, a continuous tone sounds from the
parking system when the distance to an ob-
ject is less than approximately 0.7 ft
(0.20 m). Do not continue driving farther.
G) Tips
— The segments in the side area* are detected
and analyzed when passing. There may have
been changes to the surrounding area after
switching the ignition off and on again, af-
ter opening the doors, or if the vehicle is left
stationary for a long period of time. In this
scenario, the side area* will appear black
until the area has been detected and evalu-
ated.
— If the distance to an obstacle remains con-
stant, the volume of the distance warning
gradually lowers after a few seconds until it
is muted (this does not apply to the continu-
ous tone). If the obstacle comes closer than
it was before the sound was muted, the
tone will sound again. If the obstacle be-
comes farther away than it was before the
sound was muted, no tone will sound. Pay
attention to the vehicle's surroundings
when you start to drive.
— There is no distance warning for the rear
and the sides* when trailer towing mode is
detected. The front sensors remain activat-
ed. The visual display switches to trailer
mode. There is no guarantee the functions
will switch off when using a retrofitted trail-
er hitch.

@) Note
— The orange orientation lines @ show the di-
rection the rear of the vehicle will be travel-
ing, based on the steering wheel angle. The
front of the vehicle swings out more than
the rear of the vehicle. Maintain plenty of
distance so that an exterior mirror or a cor-
ner of the vehicle does not collide with any
obstacles.
— Keep enough distance from the curb to
avoid damage to the rims.
— Only use the images provided by the camera
on the rear of the vehicle when the luggage
compartment lid is completely closed. Make
sure any objects you may have mounted on
the luggage compartment lid do not block
the rearview camera.

Assisted parking
(er eee)
Applies to: vehicles with park assist
If your vehicle is equipped with park assist, this
system helps you find suitable parking spaces.
Parking spaces are measured using ultrasonic
sensors on the sides of the vehicle.
If a parking space is found, the system helps you
to park while the driver monitors the vehicle's
surroundings with the parking aids, cameras”,
and direct eye contact. The vehicle moves the
steering wheel autonomously.

Follow the safety precautions and note the
limits of the assist systems, sensors, and
cameras > page 104.

Options for exiting parking spaces
@ Exiting parallel parking spaces

You can also drive into a perpendicular park-
ing space yourself and then activate the sys-
tem. If this is the case, the front of the vehi-
cle should already be in the space (4) so that
the sensors can measure the space.

Parking and maneuvering

The driver must decide if the parking space
displayed is suitable for the vehicle.
— Certain conditions near the parking space
may cause the parking process to fail, such
as if the parking space is near trees or posts,
or if the ground is covered, for example,
with gravel, snow, or ice.
G) Tips
— If you did not drive past a suitable parking
space too quickly, you can also select Pe to
activate the system afterwards.
— The Electronic Stabilization Control (ESC)
must not be switched off during the parking
process. If the ESC intervenes, the parking
process
will be canceled.
— You can also drive into a perpendicular park-
ing space yourself and then activate the sys-
tem. If this is the case, the front of the vehi-
cle should already be in the space (4)
= page 134, fig. 116 so that the sensors
can measure the space.
— You cannot park with the parking assist sys-
tems when you are towing a trailer or have
the connector inserted in the trailer socket.
— The system is not available when certain as-
sist systems are switched on.
— If there are suitable parking spaces on both
sides of the street, for example on a one-
way street, you can change the side where
the system is searching for parking spaces
by activating the turn signal for the other
side or by pressing on that side in the center
display.
— The park systems do not provide support for
assisted parking on tight curves.
Park assist
(eT eeeeue lela)
Applies to: vehicles with park assist
The park assist helps you when parking and exit-
ing parking spaces after the parking space
search. The park assist takes over the steering of
the vehicle while the driver accelerates, brakes,
and
monitors the vehicle's surroundings. Park as-
sist can be interrupted at any time.
136

Z\ WARNING
— Follow the safety precautions and note the
limits of the assist systems, sensors, and
cameras > page 104.
— The driver is always responsible when enter-
ing or exiting a parking space and during
similar maneuvers.
— Do not use this function if the vehicle cannot
move freely, for example when on a vehicle
jack.
— Sensors and cameras have spots in which
the surrounding area cannot be detected.
Objects, animals, and people may only be
detected with limitations may not be detect-
ed at all. Always monitor the traffic and the
vehicle's surroundings directly and do not
become distracted.
@) Note
— Do not use the park assist systems when
transporting cargo that extends out of the
vehicle, when snow chains are mounted, or
when the parking space is on a hill or in-
cline.

— Park assist guides the vehicle either away
from curbs or onto them if other vehicles
are parked on the curb. Make sure that your
vehicle's tires and rims are not damaged.
Resume control of the vehicle in time or
stop the parking process if needed to pre-
vent damage.
G) Tips
Follow the legal regulations in the country
where you are located when using Park assist.

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 make 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 placard
(tire inflation pressure label)
=> page 226, fig. 152.
2. Determine the combined
weight of the driver and pas-
sengers that will be riding in
your vehicle.
3. Subtract the combined weight
of the driver and passengers
from “XXX” kilograms or “XXX”
pounds shown on the sticker
=> page 226, fig. 152.
4. The resulting figure equals the
available amount of cargo and
luggage load capacity. For ex-
ample, if the “XXX” amount
equals 1400 lbs. and there will
230
be five 150 lbs. passengers in
your vehicle, the amount of
available cargo and luggage
oad capacity is 650 lbs.
(1400-750 (5 x 150) = 650
bs.)
5. Determine the combined
weight of luggage and cargo
being loaded on the vehicle.
That weight may not safely ex-
ceed the available cargo and
uggage load capacity calculat-
ed in Step 4.
6. If your vehicle will be towing a
trailer, load from your trailer
will be transferred to your vehi-
cle. Consult this manual to de-
termine how this reduces the
available cargo and luggage
load capacity of your vehicle.
>Check the tire sidewall
(=> page 217, fig. 149) to deter-
mine the designated load rating
for a specific tire.
Wheel bolts and rims
Wheel bolts

Wheel bolts must be clean and loosen/tighten
easily. You will need a special adapter to loosen
the anti-theft wheel bolts* > page 243.
Rims
Rims with a bolted rim ring* or with bolted wheel
covers* consist of multiple pieces. These compo-
nents were bolted together using special bolts
and a special procedure. You must not repair or
disassemble them > A\.

Emergency assistance
