Driving with an insufficient oil level is likely to
cause severe damage to the engine.
@ Tips
-The oil pressure warning display. is not
an indicator of the oil level. Do not rely on
it. Instead, check the oil level in your en­
gine at regular intervals, preferably each
time you refuel, and always before going
on a long trip.
-If you have the impression your engine con­
sumes excessive amounts of oil, we recom­
mend that you consult an authorized Audi
dealer to have the cause of your concern
properly diagnosed. Keep in mind that the
accurate measurement of oil consumption
requires great care and may take some
time. An authorized Audi dealer has instruc­
tions about how to measure oil consump­
tion accurately.
Checking the engine oil level and adding
engine oil
The engine oil level can be checked in the Info ­
tainment system
Fig. 269 Engine compa rtment: eng ine oil filler opening
cove r
Checking the engine oil level
- Park the vehicle on a level surface.
- Shut the engine off when it is warm.
0 N
-N
" 00 IX)
-Switch only the ignition back on. Wait approxi-
mately two minutes so that the engine oil can
flow back into the oil pan .
Checking and Filling
- Select in the Infotainment system: the !MENUI
button > Vehicle > left control button > Service
& checks > Oil level.
-Check the oil level in the Infotainment system
display. Add engine oil if the bar in the oil level
indicator is just before "min".
Adding engine oil Follow the safety precautions
~&. in Working in
the engine compartment on page 323.
- Stop the engine and open the hood
~page 324 .
-Unscrew the cap~ on the engine oil filling
opening
~ fig. 269, Qpage 325.
- Carefully add O .S quart (O .S liter) of the correct
oil
~ page 325.
- Close the engine oil filler opening cap.
- Close the hood, restart the ignition after two
minutes and read the current oil level in the In ­
fotainment system.
A WARNING ...__ --When adding oil, do not let oil drip onto hot
engine components. This increases the risk
of afire.
-You must secure the cap on the oil filler
opening correctly so that oil does not leak
out onto the hot engine and exhaust system
when the engine is running, because this is
a fire hazard.
-Always clean skin thoroughly if it comes into
contact with engine oil.
0 Note
- The engine oil level must not be under the
"min" marking, because this increases the
risk of engine damage.
- If the message II Please reduce oil level
appears, there is too much oil in the engine
and there is a risk of damaging the catalytic
converter and engine. Do not start the en­
gine. Contact an authorized Audi dealer or
authorized Audi Service Facility to have ex­
cess engine oil extracted if necessary.
- Do not mix any additional lubricants into
the engine oil. Damage caused by such addi-
tives is not covered by the warranty.

Bead separa tion
means a breakdown of the bond
between components in the bead.
Cord
means the strands forming the
plies in the tire .
Cold tire inflation pressure
means the tire pressure recom­
mended by the vehicle manufac­
turer for a tire of a designated size that has not been driven for
more than a couple of miles (kilo­
meters) at low speeds in the
three hour period before the tire
pressure is measured or adjusted .
Curb weight
means the weight of a motor ve­
hicle with standard equipment in­
c luding the maximum capac ity of
fuel, oi l, and coolant, a ir condi­
tioning and add itional weight of
optional equipment.
E xtra load tire
means a tire designed to operate
at higher loads and at h igher in ­
flation pressures than the corre­ sponding standard tire. Extra load
tires may be identified as
"X L",
"xl", "E XTRA LOAD" , or "RF" on
the s idewal l.

Gross Axle Weight Rating

of a single axle system, measured

Gross Vehicle Weight Rating
(" GVWR ")
means the max imum total loaded
weight of the vehicle.
Groove
means the space between two ad­
jacent tread ribs .
Load rating (code)
means the maxim um load that a
tire is rated to carry for a given in­

cause it is not required by law.
Maximum load rating
means the load rating for a tire at
the maximum permissible infla­

-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
trol.
-Incorrect tire pressure in­
creases tire wear and has a
negative effect on driving and
braking behavior, which in­
creases the risk of an accident .
(D Note
Replace lost valve caps to re­
duce the risk of damage to the
tire valves.
Tire pressure table
Please note that the information
contained in the following table
was correct at the time of print­ ing, and the information is sub­
ject to change. If there are differ­
ences between this information
and the tire pressures specified
on the label on the driver's side B­
pillar, always follow the specifica­
tion on the B -pillar label

'® For the sake of the environment
-Tire pressure that is too low
increases fuel consumption.
-Fuel consumption may also in­
crease when driving with the
comfort tire pressure is se­
lected.
Audi recommends using the
tire pressure specified for a
normal load
¢ table on
page 346
or for a full load
when the vehicle is partially
loaded.
Make sure that the tire designa­
tion on your tire matches the des­ ignation on the tire pressure label
and the tire pressure table.
The following table lists recom­ mended tire pressures in cold
tires according to the load and
the size of the tires installed .

Please note the important safe­

pressure

Tires and vehicle load limits
There are limits to the amount of
load or weight that any vehicle
and any tire can carry. A vehicle
that is overloaded will not handle
well and is more difficult to stop.
Overloading can not only lead to
loss of vehicle control, but can al­
so damage important parts of the
vehicle and can lead to sudden
tire failure, including a blowout and sudden deflation that can
cause the vehicle to crash.
Your safety and that of your pas­ sengers also depends on making
sure that load limits are not ex ­
ceeded. Vehicle load includes ev­
erybody and everything in and on
the vehicle. These load limits are
technically referred to as the vehi­ cle's
Gross Vehicle Weight Rat­
ing
("GVWR").
The "GVWR" includes the weight
of the basic vehicle, all factory in­
stalled accessories , a full tank of
fuel, oil, coolant and other fluids
Wheels
plus maximum load. The maxi­
mum load includes the number of
passengers that the vehicle is in­
tended to carry ("seating capaci­
ty") with an assumed weight of
150 lbs (68 kg) for each passen­
ger at a designated seating posi­
tion and the total weight of any
luggage in the vehicle. If you tow
a trailer, the weight of the trailer
hitch and the tongue weight of
the loaded trailer must be includ­ ed as part of the vehicle load .
The
Gross Axle Weight Rating
( " GAWR ") is the maximum load
that can be applied at each of the
vehicle's two axles.
The fact that there is an upper
limit to your vehicle 's Gross Vehi­
cle Weight Rating means that the
total weight of whatever is being
carried in the vehicle (including
the weight of a trailer hitch and
the tongue weight of the loaded
trailer) is limited. The more pas­
sengers in the vehicle or passen­
gers who are heavier than the
standard weights assumed mean
that less weight can be carried as luggage.

load that can be applied at each axle of the vehi­
cle¢&_ .
Vehicle c apacity w eight
The vehicle capacity we ight (max . load) is listed
on the driver 's side B -p ill ar respectively on the
front end of the driver's door.
_& WARNING
-The actual Gross Axle Weight Rating at the
front and rear axles should not exceed the
permissible weights, and their comb inat ion
must not exceed the Gross Veh icle Weight
Rating.
- Exceeding permiss ible weight ratings can
result in veh icle damage, acc idents and pe r­
sonal i njury .
Dimensions
(D Note
-The veh icle capacity weight figures apply
when the load is d istr ibuted evenly in the
vehicle (passengers and luggage). When
transport ing a heavy load in the luggage
compartment, carry the load as near to the
rea r axle as possible so that the ve hicle's
hand ling is not impaired .
- Do not exceed the maximum perm iss ible
axle loads or the maximum gross veh icle
we ight. Always remember that the ve hicle's
hand ling will be affected by the extra load.
Th erefore, a djust your speed acco rdingly.
- Always observe local regulations.
