Refrigerator
Introduction
Applies to: vehicles with refrigerator
Clean the refrigerator before the first use ~ table
on page 308.
You can only switch the refrigerator on, if :
- the temperature in the luggage compartment
is less than 131
° F (55 °(). If the refrigerator is
switched on , it will automatically switch off if
the temperature in the luggage compartment
exceeds 131
° F (55 °(). If the temperature
goes back below 131
° F (55 °(), the refrigera­
tor will automatically switch on again.
- The charge level of the vehicle battery is suffi.
cient. The refrigerator is automatically switch­
ed off if the electrical system voltage falls be­
low the spec ified minimum value. This prevents
the vehicle battery from discharging . The re­
frigerator automatically switches back on if th e
electrical system voltage increases again, for
example after starting the vehicle.
When the cooling function is working optimally,
the cooling function reaches 43° F
(+6 °C) and
the free zing function reaches 21 ° F
(-6 °C). The
cooling temperature in the refrigerator also de­
pends on the luggage compartment tempera­
ture. When the temperature in the luggage com­
partment is high, there may only be a limited
cooling effect.
.&, WARNING
-
To avoid any injury risks to the passengers
caused by the refrigerator, the following safe­
ty precautions must be followed:
Seats and storage
-The maximum load capacity for the freezer
is
5.5 lbs (2 .5 kg).
- Never overload the refrigerator. There is a
risk of injury in the event of a collision or
sudden braking.
- The refrigerator cover must always be
closed and locked while driving. The refrig­
erator contents could enter the vehicle inte­
rior during a collision or sudden braking ma­
neuver, which increases the risk of injury.
- Never store flammable fluids, gas contain­
ers and similar objects in the refrigerator
due to the risk of an explosion . This also ap­
plies to goods and products that can emit
volatile or flammable gases.
-At temperatures of 32° F
(0 °() and lower,
frozen liquid inside glass containers can
cause the containers to burst.
(D Note
- The ventilation openings for the refrigerator
are at the rear panel trim panel in the lug­
gage compartment and must not be cov­
ered.
- If the refrigerator is not functioning correct­
ly, turn it off to prevent any damage. Have it
checked by an authorized Audi dealer or au­
thorized Audi Service Facility.

Description
The climate con trol system warms, coo ls and re ­
moves humidity from the air in the vehicle inte ri­
or. It is the most effective when the w indows and
sunroof* are closed. If there is a bu ild-up of heat
i n side the veh icle, ven tilat ion can he lp to speed
up the cooling process .
In a ll heating mode functions, except for defrost,
the blower on ly switches to a higher speed once
the eng ine coolant has reached a sufficient tem­
perature.
Pollutant filt er
The po llutant filter removes pollutants such as
d ust and pollen from the air.

Adjusting the temperature
Temperatures between 60 °F ( +16 °C) and 84 °F
(+28 °C) can be set . Outside of this range,
LO or
HI will appear in the climate control system dis­
p lay . At both of these settings, the climate con ­
trol system runs continuously at maximum cool­
ing or heating power. There is no temperature
regulation.
~ Adjusting the amount of air
You can adjust the airf low manually to su it your
needs. The blower should always run at a low set ­
ting to prevent the windows from fogging and to
ensure a continuous exchange of air inside the
vehicle. To have the airflow regulated automat i­
cally, press the

General information
Breaking in
A new vehicle must be broken in, and the break­
in distance should be 1,000 mi les ( 1,500 km). Do
not drive at speeds that w ill exceed
2/3 of the
maximum permitted engine speed
(RPM) for the
first 600 miles (1,000 km) , and avoid full accel­
eration during this period . You may gradually
start increasing the
RPM and the speed between
600 miles (1,000 km) and 1,000 miles (1,500
km).
During the first hours of use, the engine has a
higher internal friction than later on when all
moving parts have settled into place with each
other.
How the vehicle is driven during the first 1,000
miles (1,500 km) also affects the engine quality.
Drive at moderate engine speeds after the initial
break-in per iod, part icularly when running a cold
engine . This will reduce engine wear and improve
the mileage .
Do not drive at too low of an engine speed (rpm).
Shift down if the engine stops running "smooth­
ly" . Extremely high eng ine speeds are automati ­
cally reduced .
New tires
If your vehicle is running on new tires, drive pa r­
ticularly careful for the first 350 miles (500 kilo­
meters) after fitting .
.&_ WARNING
-
New tires tend to be slippery and must also
be "broken-in". Be sure to remember this dur­
ing the first 350 miles (500 kilometers).
Brake gently . Avo id following closely behind
other vehicles or other situations that might
require sudden, hard brak ing.
Avoid damaging the vehicle
When you are driving on poor roads, or over
curbs, steep ramps, etc., make certain that low-
Driving
lying parts such as spoilers and exhaust system
parts do not bottom out and get damaged .
T h is is espec ially true for veh icles with low-s lung
chass is (sports chassis)* and fully loaded
vehicles .
Driving through water on roads
Note the following to reduce the risk of vehicle
damage when driving through water, for example
on flooded roads:
- The water must not be any higher than the bot­
tom of the vehicle body.
- Do not drive faste r than walk ing speed.
.&_ WARNING
=
After driving through water or m ud, the effec-
tiveness of the brakes may be reduced due to moisture on the brake rotors and brake pads.
A few careful brake applications should dry
off the brakes .
(D Note
-Vehicle components such as the engine,
transmission, suspension or electrical sys­
tem can be severely damaged by driving
through water.
- Always switch off the Start/Stop system
when driving through water r::;,page
78.
{i) Tips
- Determine the depth before driving through
water.
- Do not stop the vehicle, drive in reverse or
switch the engine off when driving through
water.
- Keep in mind that oncom ing vehicles may
create waves that raise the water level and
make it too deep for your vehicle to drive
through safely.
- Avoid dr iving through salt water, because
this can cause corrosion .

CD Note
Do not leave engine idling unattended after
starting . If warning lights should come on to
ind icate improper ope ration, they wou ld go
unheeded. Extended idling also produces
heat, wh ich could result in overheat ing or
other damage to the vehicle or other proper­
ty .
CD Note
- Have your vehicle maintained properly and
in accordance with the service recommenda­
tions in you r War ranty
& Ma intenance book­
l et. Lack of p roper maintena nce as well as
i mproper use of the vehicle will imp air the
funct ion of the emission contro l system and
could lead to damage.
- Do not alter or remove any component of
the Em ission Control System un less ap­
proved by the manufacturer .
- Do no t alt er or remove any devi ce, such as
heat shie lds, switches, ignition wires,
valves, which are designed to protect your
vehicle's Em ission Control System and other
i mportant veh icle components .

could be started or electrical equipment
such as the power windows could be operat­
ed. This can lead to serious injury.
- For safety reasons, always park the vehicle
with the selector lever in the P position.
Driving
Otherwise, there is the risk that the vehicle
could roll unintentionally.
@ Note
If the engine has been under heavy load for
an extended period of time, heat builds up in
the engine compartment after the engine is
switched off and there is a risk of damaging
the engine. For this reason, let the engine run
at idle for approximately two minutes before
shutting it off.
(D Tips
After the engine has been switched off, the
radiator fan can continue to run for up to 10
minutes -even with the ignition switched off .
It can also switch on again after some time if
the coolant temperature rises as the result of
heat buildup or if the engine is already warm
and the engine compartment is also heated
by the sun's rays.
