Changing the engine oil
We recommend that have your oil changed by an
authorized Audi dealer or a qualified service sta­ tion.
Before you check anything in the engine compart ­
ment,
always r ead and heed all WARNINGS Q .&.
in Working in the engine compartment on
page 233.
The eng ine o il must be changed according to the
i nterva ls spec ified in your Warranty
& Ma inte­
nance boo klet . This is ve ry importa nt because the
.,..

Cl 00 .-< N r-­N .-< 0 r-­Vl 00
lubricating properties of oil diminish gradually
during normal vehicle use.
Unde r some c ircu mstances the eng ine o il should
be changed more frequently . Change oil mo re of­
ten if you drive most ly short distances, ope rate
the vehicle in dusty areas or under predominant ly
stop-and -go traffic condit ions, or have your vehi­
cle where temperatures remain below free zing
for extended periods.
Detergent additives in the oil will make fresh oil
l ook dark after the engine has been running for a
short time. Th is is normal and is not a reason to
change the oil more often than recommended.
Because of the problem of proper disposa l, along
with the special tools and necessary expertise re­
qu ired, we strongly recommend that you have
your oil changed by an authorized
A ud i de ale r or
a qualified service station .
If you c hoo se to change your o il y our self , please
note the following important information:
A WARNING
To reduce the risk of personal injury if you
must change the engine oil in your veh icle
yourself:
- Wear eye protection .
- To reduce the risk of burns from hot engine oil, let the eng ine cool down to the touch.
-
- When removing the o il drain plug with your
fingers, stay as far away as poss ible. A lways
keep your forearm paralle l to the ground to
help prevent hot o il from runn ing down your
arm .
- Drai n the oil into a container designed for
this pu rpose, one large enough to hold at
least the total amount of oil in your e ng ine .
- Engine oil is poisonous . Keep it well out of
the reach of ch ild ren .
- Cont inuous contact w ith used eng ine oi l is
harmful to your sk in. A lways protect your
sk in by washing oil off thoroug hly w ith soap

To reduce the risk of lime sca le deposits on the
spray nozzles, use clean water with low amounts
of calc ium. A lways add window cleaner to the wa­
ter. When the outs ide temperatures are cold, an
anti -freezing agent should be added to the water
so that it does not freeze.
@ Note
-The concentration of anti-freezing agent
must be adjusted to the vehicle operating
cond itions in the respective climate. A con­
ce ntrat ion that is too high can lead to vehi­
cl e damage.
- Never add radiator anti-freeze or other addi­
tives to the washer fluid.
Checking and Filling
- Do not use a glass cleaner that contains
paint so lvents, because t his could damage
the paint.

-The tire must flex more if the
tire pressure is too low or if
the vehicle speed or load are
too high. This heats the tire up
too much. This increases the
risk of an accident because it
can cause the tire to burst and result in loss of vehicle con ­

Please note that the TPMS is not a substitute for
proper tire maintenance, and it is the driver's re­
sponsibility to maintain correct tire pressure,
even if under-inflation has not reached the level
to trigger illumination of the TPMS low tire pres­
sure telltale .
Your vehicle has also been equipped with a TPMS malfunction indicator to indicate when the sys­
tem is not operating properly. The TPMS mal­
function indicator is combined with the low tire pressure telltale. When the system detects a
malfunction, the telltale will flash for approxi­
mately one minute and then remain continuously
illuminated. This sequence will continue upon
subsequent vehicle start-ups as long as the mal­
function exists.
When the malfunction indicator is illuminated,
the system may not be able to detect or signal
low tire pressure as intended. TPMS malfunctions
may occur for a variety of reasons, including the
installation of replacement or alternate tires or
wheels on the vehicle that prevent the TPMS
from functioning properly . Always check the
TPMS malfunction telltale after replacing one or
more tires or wheels on your vehicle to ensure
that the replacement or alternate tires and
wheels allow the TPMS to continue to function
properly.
Description
Applies to: vehicles with tire pressure monitor ing system
The tire pressure monitoring system monitors
the pressure in the four tires when driving.
T he system uses sensors that measure the tem ­
perature and pressure in the tires . The data is
sent from these sensors to the control module by radio frequency.
T he tire pressure monitoring system shows the
current pressures and temperatures of the tires
in the Infotainment system while driving
¢ page 264. It also compares the current tire
pressures with the stored tire pressures and
gives a warning if the tire pressure is different
from what is stored
¢ page 264 .
Wheels
The system does not detect if the stored tire
pressures match the recommended tire pres­
sures. You must store the tire pressures again
¢ page 264:
- every time the tire pressures change, for exam­
ple when the load in the vehicle changes,
- after replacing a tire, or
- if wheels with new wheel sensors are used.
_& WARNING
- The tire pressure monitoring system assists
the driver in monitoring tire pressures. The
driver is responsible for having the tires in­
flated to the correct pressure.
- Do not change the tire pressure when the
temperature of the tire is extremely high.
This could result in serious damage to the
tire and even cause the tire to burst, in­
creasing the risk of an accident.
- A tire with low pressure flexes more. This heats the tire up too much. This could cause
the tread to separate and even cause the
tire to burst, increasing the risk of an acci­
dent.
- The tire pressure monitoring system does not warn about damage or defects in the
tire construction that could cause the tire to
burst, for example. Inspect your tires regu­
larly.
(D Tips
- If tires are replaced, the sensors/valves do
not need to be removed or replaced . Just re­
placed the valve stem and, if necessary, the
valve and the wheel electronics. If you have questions, see an authorized Audi dealer or
authorized Audi Service Facility.
- An incorrect display or a malfunction in the
tire pressure monitoring system can occur
after using the tire mobility kit. Have the
sensors replaced by an authorized Audi
dealer or authori zed Audi Service Facility.
- For an explanation on conformity with the
FCC regulations in the United States and the
Industry Canada regulations, see
