The Ad Blue filler t ube is located near the d iesel
filler t ube. Add at least 1.5 gallons (5.7 lite rs) of
AdBl ue. This is the min imum amount required to
ensure the system detects the refilling and to
sta rt the eng ine . You can add a maxim um of ap­
prox imately 4 . 5 gallons ( 17 li ters) .
Requirement: The request to add Ad Blue must
appear in the instrument cluster display.

CJ) Note
-Only use Ad Blue that conforms to the
standard ISO 22241-1. Do not mix any addi­
tives with the AdBlue and do not dilute it
with water.
- Do not add Ad Blue to the diesel tank or add diesel fuel to the AdBlue tank. Mixing can
lead to damage to the engine and the Ad Bl­
ue tank system .
- AdBlue attacks surfaces such as painted ve­
hicle components, plastic and carpet. Re­
move the fluid as quickly as poss ible with a
damp cloth and plenty of cold water . If the
Ad Blue has already crysta llized, use warm
water and a sponge. Ad Blue residue that is
not removed will crysta llize and can damage
the affected surface.
- Do not store refill bott les or canisters per­
manently in the vehicle. If the container
l eaks, the escaping AdBlue could damage
the vehicle interior.
- Do not allow Ad Blue to come into contact
with clothing. If there is contact with the
fluid, flush immediately with plenty of wa­
ter.
{D) Tips
Follow the Ad Blue manufacturer's instruc­
tions for use and storage .

Checking and Filling
@ 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 consu Lt your Audi dealer to
have the cause of your concern properly di­
agnosed . Keep in mind that the accurate
measurement of oil consumption requires
great care and may take some time. Your
Audi dealer has instructions about how to
measure oil consumption accurately.
Checking the engine oil level
The engine oil level can be checked in the Info­
tainment system
Fig. 187 I n fo tai nme nt: oil level indic a to r
• Park your vehicle on a level surface.
" Shut the engine off when it is warm .
.. Switch only the ignition back on.
.. Wait approximately two minutes.
" Select : the
ICAR I function button > (Car)* Sys­
tems
control button > Service & control > Oil
level.
.. Check the oil level in the Infotainment system
display ¢
fig. 187. Add engine oil if the bar of
the oil level indicator is near "min"
¢page 220.
Depending on the way the vehicle is driven and
the operating conditions, oil consumption can be
up to 1/2 quart per 600 miles (0 .5 liter per
220
1,000 km). Consumption may be higher within
the first 3,000 miles (5,000 km).
Because of this, the engine oil level must be
checked regularly. It would be best to check each
time you refuel your vehicle and before long
drives.
{!) Tips
The oil level indicator in the instrument clus­
ter display is only an informational display. If
the oil level is too low, a minimum oil warning
appears in the instrument cluster. Add oil. If
the hood was opened, the current oil level is
shown in the instrument cluster the next time
the ignition is switched on.

and follow the important safe­
ty precautions in

Tires and vehicle load limits.
-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

Please note that the information

ject to change. If there are differ­

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.
@ For the sake of the environment
Tire pressure that is too low in­
creases fuel consumption.
(D Tips
Audi recommends using the
tire pressure specified for a normal load
q table on
page 243
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. ..,

Wheels
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
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 1 SO 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-
244
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.
The Gross Vehicle Weight Rating
and the Gross Axle Weight Rating
are listed on the safety compli­
ance sticker label located on the
driver's side B-pillar
¢ page 241,
fig. 195.
&_ WARNING ~
Overloading a vehicle can cause
loss of vehicle control, a crash
or other accident, serious per­
sonal injury, and even death.
-Carrying more weight than your vehicle was designed to carry will prevent the vehicle
from handling properly and increase the risk of the loss of
vehicle control.
-The brakes on a vehicle that has been overloaded may not
be able to stop the vehicle
within a safe distance.

Winter tires
Winte r ti re s s ignificantly improve the veh icle's
h a ndling when d riving in w inte r condi tions. Be­
c a use of the ir cons tru ction (width, compound,
tread pattern), summe r tires provide less trac­
tion o n ice and snow.
246
.,. Use win ter tires on a ll four wheels .
.. On ly use winter tires that are approved for yo ur
veh icle.
.,. Please note that the maximum permitted
speed may be lower with winter tires¢&_ .
Your authorized Audi dealer or authorized re ­
pa ir fac ility can inform you about the maxim um
permitted speed for your t ires .
.,. Check t he tire p ressure afte r insta lling wheels
~ page 241.
The effectiveness of wi nter tires is reduced g reat­
l y when the tread is wo rn down to a depth of
0.157 inch ( 4 mm). The chara cte ris tic s of winter
ti res a lso decrease g rea tly as the t ire ages, re­
gard less o f the remaining t read.
_&. WARNING
- Never drive faster than the maximum pe r­
m itted speed for your tires . This could cause
the t ires to heat up too much. This increases
the risk of an accident because it can cause
the t ire to burst .
- Always adapt your driving to the road and
traffic conditions . Drive carefully and reduce
your speed on icy or slippery roads . Even
winter t ires can lose t ract io n on black ice .
@ For the sake of the environment
Reinstall summer tires at the appropr iate
time, because they prov ide better handling
when roads are free of snow and ice. Summer
tires cause less road no ise, tire wear and fuel
consumpt ion.
(i_) Tips
You can also use all season tires instead of
winter tires . Please note that in some coun­
tries where wint er tires are required, o nly
winter tires w it h t he
& symbol may be per­
mi tted.
Snow chains
Snow chains improve trac tion in the snow.
