Z\ WARNING
— Observe the safety precautions and note the
limits of the assist systems, sensors, and
cameras > page 121.
— The rear cross-traffic assist will not provide
alerts about people and cannot warn you
about every type of approaching objects,
such as cyclists. Always monitor the traffic
as well as the vehicle's surroundings with di-
rect eye contact.
— The system may not react if objects are ap-
proaching very quickly.
— The rear cross-traffic assist will not provide
alerts if your vehicle is parallel parked or if
your vehicle is pulled too far into the park-
ing space so that it is hidden by adjacent
vehicles.

@) Tips
— Once an automatic brake activation occurs,
the system cannot initiate another activa-
tion for several seconds.
— System functions may not be available if the
ESC is limited or switched off, or if there is a
malfunction.
— If there is an acoustic warning signal from
the rear cross-traffic assist, then the park-
ing aid may not warn you of detected obsta-
cles under certain circumstances.
— The system is not available when the vehicle
detects that you are towing a trailer. There
is no guarantee the functions will be deacti-
vated when using a retrofitted trailer hitch.
Do not use these functions when towing a
trailer.
— The coverage areas of the sensors > fig. 124
are diagrams and do not represent a true-
to-scale image of the sensor ranges.
— The system complies with United States FCC
regulations and ISED regulations
=> page 311.
Assisted parking
Applies to: vehicles with assisted parking
If your vehicle is equipped with park assist plus
or remote park assist plus, these systems will
help you to find suitable parking spaces. Parking
spaces are measured using ultrasonic sensors on
the sides of the vehicle. Depending on vehicle
equipment, the laser scanner may also improve
the measurement.
If a parking space is found, the systems will help
you to park while the driver monitors the vehi-
cle's surroundings with the parking aids, cam-
eras*, and direct eye contact.

ZA WARNING
Observe the safety precautions and note the
limits of the assist systems, sensors, and
cameras > page 121.

Parking and maneuvering

@) Tips
— If you did not drive past a suitable parking
space too quickly, the system can also be ac-
tivated afterward by pressing Pe.
— 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 168, fig. 126 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 upper
display.
— The park systems do not provide support for
assisted parking on tight curves.
Park assist plus!)2)
General information
Applies to: vehicles with park assist plus
Park assist plus parks the vehicle after the park-
ing space search and also exits the parking space.
While the driver presses and holds the [>>P] but-
ton and monitors the vehicle's surroundings, park
assist plus controls the steering, gear selection,
acceleration, and braking.

ZA WARNING
— Observe the safety precautions and note the
limits of the assist systems, sensors, and
cameras > page 121.
— 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 park assist plus when transport-
ing cargo that extends outside of the vehicle
or when snow chains are mounted.
— Park assist plus and remote controlled park-
ing guides the vehicle either away from
curbs or onto them if other vehicles are
parked on the curb. Make sure that your ve-
hicle's tires and rims are not damaged. Re-
sume control of the vehicle in time or stop
the parking process if needed to prevent
damage.
— In parking spaces without curbs, maintain a
distance of at least 19 inches (50 cm) from
walls and buildings in order to reduce the
risk of vehicle damage.
G) Tips
Follow the legal regulations in the country
where you are operating the vehicle when us-
ing park assist plus. Park assist plus may be
prohibited in some countries. The system may
be unavailable in countries where it has been
deactivated in order to comply with legal reg-
ulations. Data will not be transmitted to Audi. >

Wheels

Determining correct load
Talis
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 266, fig. 168.
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 266, fig. 168.
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
be five 150 lbs. passengers in
your vehicle, the amount of
available cargo and luggage
load capacity is 650 lbs.
(1400-750 (5 x 150) = 650
lbs.)
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
luggage 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 257, fig. 165) 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.
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

Inflating a tire
> Move the switch (8) > fig. 172 on the compres-
sor into position I.
> Inflate the tire to between 29 psi (200 kPA)
and 36 psi (250 kPA) and read the pressure on
the gauge.
> If this tire pressure is not reached, remove the
filler hose. Drive slowly approximately 33 feet
(10 m) forward or in reverse so that the sealant
can be distributed in the tire. Inflate the tire
again > A\.
Z\ WARNING
— Read and follow the manufacturer's safety
precautions on the compressor and in the in-
structions on the bottle of sealant.
— Ifa tire pressure of 29 psi (200 kPA) cannot
reached after inflating for 6 minutes, then
the tire is too severely damaged. Do not con-
tinue driving.
— If the tire cannot be repaired with the tire
sealant, see an authorized Audi dealer or au-
thorized Audi Service Facility for assistance.
G) 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.

> Affix the sticker that says "max. 50 mph (max.
80 km/h)" that is provided with the tire mobili-
ty kit within the driver's field of vision.
> Stop 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.

ZA WARNING
Pay attention to the following after repairing
the tire:
— Do not drive faster than 50 mph (80 km/h).


— Avoid hard acceleration or braking and driv-
ing fast around curves.
— The vehicle may become more difficult to
control.
— If the tire is too severely damaged, see an
authorized Audi dealer or authorized Audi

@) Tips
Make sure that the connected jump start ca-
bles have sufficient contact with metal.
Towing
General information
You should only perform the steps that follow if
you have the necessary tools and technical ex-
pertise.
Towing requires a certain amount of practice.
Audi recommends contacting a towing company
to have the vehicle transported.
You should only have your vehicle towed by an-
other vehicle when disabled in exceptional cir-
cumstances. Inexperienced drivers should not
tow.
Notes on towing
When the engine is stopped, the transmission
will not be sufficiently lubricated if traveling at
high speeds and long distances:
— The maximum permitted towing speed is 30
mph (50 km/h).
— The maximum permitted towing distance is 30
miles (50 km).
Additional information on towing with a tow
truck
The vehicle may only be towed with the front axle
raised. Do not wrap any chains or cables around
the brake lines.
Tow bar and towing cable
The vehicle can be towed with a tow bar or tow-
ing cable. Both drivers should be familiar with
the special considerations when towing, especial-
ly when using a towing cable.
Always make sure the traction force does not ex-
ceed the permitted level and there are no shock
loading conditions. There is always the risk of the
coupling becoming overloaded when driving off-
road.
For the most safety and security, drive with a tow
bar. You should use a towing cable only if a tow
bar is not available. Use a towing cable made of
synthetic elastic cable similar elastic material.

ZA WARNING
— Towing highly increases the risk of an acci-
dent, for example from colliding with the
towing vehicle.
— To reduce the risk of an accident, do not al-
low anyone to remain inside the vehicle
when it is being transported by a tow truck
or a special transporter.
@) Note
— If normal towing is not possible, for exam-
ple if the transmission is faulty or if the
towing distance is greater than 30 miles
(50 km), then transport the vehicle on a
special carrier.
— If the vehicle is towed by a tow truck at the
axle that is not permitted, this can cause se-
vere damage to the transmission.
— The vehicle must not be tow started for
technical reasons.
@) Tips
— If the power supply is interrupted, then it
will not be possible to move the selector
lever out of the "P" position. The parking
lock must be released using the emergency
release before towing the vehicle
=> page 100.
— Switch Audi pre sense* off > page 152 when
loading the vehicle onto a vehicle carrier,
train, ship, or other type of transportation,
or when towing the vehicle. This can prevent
an undesired intervention from the pre
sense* system.
— Follow the local legal regulations for tow-
ing.
Read and follow the important information under
=> page 295. >

Emergency assistance

Preparations
> Only secure the towing cable or tow bar at the
designated towing loops > page 296,
=> page 297.
> Make sure the towing cable is not twisted. Oth-
erwise it could disconnect from the towing loop
while towing.
> Switch the emergency flashers on in both
vehicles > page 53. However, do not do this if it
prohibited by law.
Towing vehicle (front)
> Only start to drive when the towing cable is
taut.
> Press the brake pedal very carefully.
> Avoid sudden braking or driving maneuvers.
Vehicle being towed (rear)
> Make sure the ignition is switched on so that
the steering wheel is not locked and so that you
can use the turn signals, the horn, and the
windshield wipers if needed > /\.
> Switching it off before the vehicle has stopped
may impair the function of the brake booster
and power steering. You would then need to
use more force to steer and brake the vehicle.
> Release the parking brake > page 106.
> Select the “N” selector lever position.
> Make sure the towing cable is always taut.


Z\ WARNING
— Never tow a vehicle using a tow bar or tow-
ing cable if the vehicle does not have electri-
cal power.
