Warm and cold

Warm and cold
Climate control system
Your vehicle has a deluxe automatic climate con-
trol system with four zones where the tempera-
ture, air distribution, and amount of air can be
adjusted separately at every seat.
The climate control system warms, cools, dehu-
midifies, and filters the air in the vehicle interior.
It is the most effective when the windows and
panoramic glass roof* are closed. If there is a
build-up of heat inside the vehicle, ventilation
can help to speed up the cooling process.
The deluxe climate control system automatically
maintains a temperature once it has been set. In
all heating mode functions except defrost, the
blower only switches to a higher speed once the
coolant has reached a certain temperature.
Pollutant filter
The pollutant filter removes pollutants such as
dust and pollen from the air.
@ For the sake of the environment
Energy can be saved by switching off the A/C
mode.
G) Tips
— To prevent interference with the heating or
cooling output and to prevent the windows
from fogging over, the air intake in front of
the windshield must be free of ice, snow,
and leaves.
— Condensation from the cooling system can
drip and form a puddle of water under the
vehicle. This is normal and does not mean
there is a leak.
— The energy management system may tem-
porarily switch off certain functions, such as
the seat heating” or rear window defogger.
These systems are available again as soon as
the energy supply has been restored.

start. Otherwise, the electronic systems in
the vehicle may be severely damaged.
— The jump start pins in the motor compart-
ment are designed specifically for qualified
technicians.
Towing
Teele ela)
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
— The maximum permitted towing speed is 30
mph (50 km/h).
274
— 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
—Ifthe |e} indicator light turns on, there is a
fault in the cooling circuit. The vehicle must
not be towed. The drive system can be se-
verely damaged.
— 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.
