_& WARNING
You or your passengers could be injured while
changing a wheel if you do not follow these
safety precautions:
- If you have a flat tire, move a safe distance
off the road. Turn off the engine, turn the emergency flashers on and use other warn­
ing devices to alert other motorists.
- Make sure that passengers wait in a safe
place away from the vehicle and well away
from the road and traffic.
- To help prevent the vehicle from moving
suddenly and possibly slipping off the jack,
always fully set the parking brake and block
the wheel diagonally opposite the wheel be­
ing changed. When one front wheel is lifted
off the ground, placing the Automatic
Transmission in P (Park) will
not prevent the
vehicle from moving.
- Before you change a wheel, be sure the
ground is level and firm. If necessary, use a
sturdy board under the jack.
- Always store the vehicle tool kit, the jack
and the replaced tire in the luggage com­
partment

.. Always store the vehicle tool kit, the jack* and
the replaced tire in the lugg age compartment
c:> page 253.
.. Check the tire pressure on the spare wheel im­
mediately after mounting it .
.. As soon as possible, have the tightening tor­
ques
on all wheel bolts checked with a torque
wrench. The correct tightening torque is
90 ft lb (120 Nm).
.. Have the flat tire replaced as soon as possible.
@ Tips
-If you notice that the wheel bolts are cor­
roded and difficult to turn while changing a
tire, they should be replaced before you
check the tightening torque.
- Drive at reduced speed until you have the tightening torques checked.
- After changing a wheel, the tire pressure in
all four tires must be checked/corrected and
the tire pressure monitoring indicator must
be stored in the MMI

Replacing light bulbs
For your safety, we recommend that you have
your authorized Audi dealer replace any bulbs for you.
It is becoming increasingly more and more diffi­
cu lt to replace vehicle light bulbs since in many
cases, other parts of the car must first be re­
moved before you are able to get to the bulb.
This applies especially to the light bulbs in the
front of your car which you can only reach
through the engine compartment.
Sheet meta l and bulb holders can have sharp
edges that can cause serious cuts, parts must be
correctly taken apa rt and then properly put back
together to help prevent breakage of parts and

(D Note
-Applying a higher voltage booster battery
will cause expensive damage to sensitive electronic components, such as control
units, relays, radio, etc.
- There must be no electrical contact between the vehicles as otherwise current could al­
ready start to flow as soon as the positive
(+) terminals are connected .
@ Tips
The discharged battery must be properly con­
nected to the vehicle's electrical system.
When jump starting or charging the battery,
never connect the negative ground cable to
the battery negative post because the battery
manager system must be able to detect the
battery's state of charge. Always connect the
negative ground cable to the negative ground
post of the battery manager control unit.
Using jump start cables
Connect the jump start cables in the exact order
described below.

Emergency situations
Plug-in hybrid drive*: The connection points for
the jump start cables
vary ¢ page 104.
The battery is located to the left in the engine
compartment. The procedure for connecting
jump start cables that is described next is de­
signed to help jump start your vehicle.
Vehicle with drained battery:
.. Read the following carefully 9 page 368
.. Set the parking brake and place the se lector
lever in the P position .
.. Turn the ignition and electrical equipment off
in both vehicles .
Connecting positive terminal(+) to positive
terminal (+)
.. To reach the battery terminals, flip the battery
cover cap to the side¢ fig. 303 .
l. Clamp the end of the red jump start cab le to
the terminal
(D c> fig. 304 on the dead bat­
tery @¢ 0 in Starting with jumper cables
on page 369 .
2. Clamp the other end of the red jump start ca­
ble to the terminal @on the charging bat­
te ry @ .
Connecting negative terminal(-) to negative
terminal (-)
3. Clamp the black end of the jump start cab le
preferably at the ground point, or on the
negative terminal @ on the charging battery
®·
4. Clamp the other end of the black jump start
cable
only to the ground point @ on your
vehicle @c>(D.
5. Route the jump start cables so they cannot
get caught in the moving parts in the engine
compartment.
Starting the engine
6. Start the engine in the vehicle giving the
charge and let it run at idle .
7. Now start the engine in the vehicle with the
dead battery and wait two to three m inutes
until it "runs smoothly" .

today's automobiles, have steadily reduced the
scope of maintenance and repairs which can be
carried out by vehicle owners.
Also, safety and
environmental
concerns place very strict limits
on the nature of repairs and adjustments to en­
gine and transmission parts which an owner can perform .
Maintenance, adjustments and repairs usually re­
quire special tools, testing devices and other
equipment available to specially trained work ­
shop personnel in order to assure proper per­
formance, reliability and safety of the vehicle and its many systems.
Improper maintenance, adjustments and repairs
can impair the operation and reliability of your
vehicle and even void your vehicle warranty .
Therefore, proof of servicing in accordance with
the maintenance schedule may be a condition for upholding a possible warranty claim made within
the warranty period.
Above all , operational safety can be adversely af­
fected, creating unnecessary risks for you and
your passengers.
If in doubt about any servicing, have it done by
your authorized Audi dealer or any other properly equipped and qualified workshop. We strongly urge you to give your authorized Audi dealer the
opportunity to perform all scheduled mainte­ nance and necessary repairs. Your dealer has the
facilities, original parts and trained specialists to keep your vehicle running properly .
Performing limited maintenance yourself
The following pages describe a limited number of
procedures which can be performed on your vehi­
cle with ordinary tools, should the need arise and
trained personnel be unavailable. Before per­
forming any of these procedures, always thor­
oughly read all of the applicable text and careful­ ly follow the instructions given . Always rigorously
observe the
WARNINGS provided .
Before you check anything in the engine com­
partment, always read and heed all WARNINGS
c::> .&. and c::> page 316 .
Consumer information
A WARNING
-Serious personal injury may occur as a result
of improperly performed maintenance, ad­
justments or repairs .
- Always be extremely careful when working
on the vehicle. Always follow commonly ac­
cepted safety practices and general com­ mon sense. Never risk personal injury.
- Do not attempt any of the maintenance,
checks or repairs described on the following pages if you are not fully familiar with these
or other procedures with respect to the ve­ hicle, or are uncertain how to proceed.
- Do not do any work without the proper tools
and equipment. Have the necessary work
done by your authorized Audi dealer or an­
other properly equipped and qualified work­
shop.
- The engine compartment of any motor vehi­ cle is a potentially hazardous area. Never
reach into the area around or touch the radi­
ator fan.
It is temperature controlled and
can switch on suddenly - even when the en­
gine is off . The radiator fan switches on au ­
tomatically when the coolant reaches a cer­
tain temperature and will continue to run
until the coolant temperature drops.
- Always switch off the ignition before anyone
gets under the vehicle.
-Always support your vehicle with safety
stands if it is necessary to work underneath
the vehicle . The jack supplied with the vehi­
cle is not adequate for this purpose and
could collapse causing serious personal in­
jury.
- If you must work underneath the vehicle
with the wheels on the ground, always make
sure the vehicle is on level ground, that the
wheels are always securely blocked and that
the engine cannot be started.
- Always make sure the transmission selector
lever (automatic transmission) is in P (Park
position) and the park brake is applied .
