Rear view camera
The rear view camera is located above the rear
license plate bracket. Make sure that the lens
for the parking system
c:> fig. 132 is not cov­
ered by deposits or any other obstructions be­
cause this can affect the function of the park­
ing system. For information on clean ing, refer
to
c:> page 214.
The rear view camera coverage area includes
(D ¢fig . 131. Only this area is shown in the
Infotainment display. Objects that are outside
of this area @are not displayed.
The accuracy of the orientation lines and the
blue surfaces is reduced if the adaptive air
suspens ion* is faulty, if the vehicle is lifted or
if the

A WARNING
-Always read and follow the applicable
warnings
c:> &. in General information on
page 120.
- If the position and the installation angle
of the rear view camera was changed, for
example, after a collision, do not contin­
ue to use the system for safety reasons.
Have it checked by your authorized Audi
dealership or authorized repair facility.
- Only use the rear view camera to assist
you if it shows a good, clear picture. For example, the image may be affected by
the sun shining into the lens, dirt on the
lens or if there is a system fault.
- Use the rear view camera only if the lug­
gage compartment lid is completely
closed. Make sure any objects you may
have mounted on the luggage compart­
ment lid do not block the rear view cam­
era.

incline , or a downward slope.
- If driven toward protruding objects.
-If the vehicle is carrying too much load
in the rear.

222 Fuel su ppl y and fillin g yo ur fu el t an k
Cold diesel engines normally produce louder
noises during winter conditions than during
warmer periods . In addition, the exhaust gas ­
es may be light blue in color until the engine has warmed up.
.&_ WARNING
Never use starting assist fluids. They may
be potentially explos ive or cause a "run­
away" engine condition . Th is could resu lt
in ser ious persona l injury and eng ine dam­
age.
- Your vehicle's diesel engine was de­ signed so ley for use with ULSD No. 2.
Therefo re, never use gaso line, heat ing
oi l or other fuels. These fuels contain
substances that will severely damage the
fuel system and the engine. Such dam­
age will not be covered by your New Ve­ hicle limited Warranty.
- If you put any amount of incorrect fue l in
the fue l tank, do not start the engine un­
der any circumstances. Immediately con­
tact the nearest authorized Audi dealer
or authorized Audi Service Facility for as­
s istance. These fuels contain substances
that can severely damage the fuel sys­
tem and the engine if the engine is start­
ed .
- Do not mix additives such as "flow im­
provers", gasoline or other substances
with ULSD No. 2.
Fuel tank
Fuel filler neck
The fuel filler neck is located on the right rear
side panel behind the fuel filler flap .
If the power locking system should fail, you
can still open the flap manually- for detailed instructions see
c> page 2 2 4 .
You can f ind the fue l tank ca pa city of your ve­
hicle in
<=> page 288.
The label on the inside of the fuel f iller flap
te lls you the correct fue l for your vehicle. For
more information about fuel specifications,
see
c> page 220.
Your vehicle fuel tank has an on board refuel­ ling vapor recovery system. This feature helps
to prevent fuel vapors from escaping from the
tank and polluting the environment while you
refuel your vehicle. In order to fill the tank
proper ly while protecting the environment,
please follow this refueling procedure careful­
ly .
.&_ WARNING
Under normal operating cond itions , never
ca rry addit ional fue l conta iners in your car .
Gas canisters and other containers used to
transport fuel can be dangerous. Such con­
tainers, fu ll or empty, may leak and could
cause a fire in a collision. If you must
transport fuel to use for your lawn mower,
snow b lower, etc ., be very careful and al­
ways observe local and state laws regard­
i ng the use, transportation and storage of
such fuel containers. Make certa in the con­
tainer meets industry standards (ANSI/
ASTM
F852 -86).
{(y Note
Never drive your veh icle until the fuel tank
i s completely empty. The irregula r supply
of fue l can cause misfir ing. Gasoline cou ld
enter the exhaust system and damage the
catalytic converter.
