– Do not use a glass cleaner that contains

paint solvents, because this could damage

the paint.

Windshield washer

system

Service interval display

The service interval display detects when your ve-

hicle is due for service.

The service interval display works in two stages:

– Inspection or oil change reminder: after driv-

ing a certain distance, a message appears in the

instrument cluster display each time the igni-

tion is turned on or off. The remaining distance

or time is displayed briefly.

Fig. 174 Engine compartment: washer fluid reservoir cap

Observe the safety precautions ðpage 250, Gen-

eral information.

– Inspection or oil change due: if your vehicle

has reached an inspection or oil change interval

or both intervals at the same time, the mes-

sage Inspection due! or Oil change due! or Oil

change and inspection due! appears briefly af-

ter turning the ignition on or off.

The windshield washer reservoir  contains the

cleaning solution for the windshield, rear win-

dow, and the headlight washer system*

ðpage 253. The reservoir capacity can be found

in ðpage 320.

Checking service intervals

To reduce the risk of lime scale deposits on the

spray nozzles, use clean water with low amounts

of calcium. Always add window cleaner to the wa-

ter. When the outside temperatures are cold, an

anti-freezing agent should be added to the water

so that it does not freeze.

You can check the remaining distance or time un-

til the next oil change or next inspection in the

Infotainment system.

Applies to MMI: Select on the home screen: VEHI-

CLE > Settings & Service > Service intervals.

Messages

Resetting the indicator

The following messages may appear, depending

on the vehicle equipment:

An authorized Audi dealer or authorized Audi

Service Facility will reset the service interval dis-

play after performing service.



Please add washer fluid

If you have changed the oil yourself, you must re-

set the oil change interval.

Fill the washer fluid for the windshield washer

system and the headlight washer system* when

the ignition is turned off.

Applies to: MMI: To reset the display, select on

the home screen: VEHICLE > Settings & Service >

Service intervals.

Note

– The concentration of anti-freezing agent

must be adjusted to the vehicle operating

conditions and the climate. A concentration

that is too high can result in vehicle dam-

age.

WARNING

Inadequate service, a lack of service, or failing

to adhere to the service intervals can result in

the vehicle breaking down in traffic, acci-

dents, and serious injuries.

– Never add radiator anti-freeze or other addi-

tives to the washer fluid.

Checking and Filling

Note

– Only reset the oil change indicator if the oil

was changed.

– Regular service work on the vehicle is not

only beneficial for sustainable use of the ve-

hicle and retention of its value, but also for

operational and traffic safety. For this rea-

son, always have service work performed ac-

cording to the Audi guidelines.

– Even if the mileage on the vehicle is low, do

not exceed the time for the next service.

– Audi is not responsible for damage to the

vehicle that occurred due to inadequate

service or insufficient part availability.

Wheels

WARNING

Tires and rims

–Never drive faster than the

maximum permitted speed for

your tires. This could cause

the tires to heat up too much.

This increases the risk of an

accident because it can cause

the tire to burst.

General information

The combination of a rim and tire

will be referred to as a wheel in

the Owner’s Manual. If only one

of the components is referred to,

then the term tire or rim will be

used.

–Always adapt your driving to

the road and traffic condi-

tions. Drive carefully and re-

duce your speed on icy or slip-

pery roads. Even winter tires

can lose traction on black ice.

►

Check your tires regularly for

damage, such as punctures,

cuts, cracks, and bulges. Re-

move foreign objects from the

tire tread.

►

If driving over curbs or similar

Note

obstacles, drive slowly and ap-

proach the curb at an angle.

–Please note that summer and

winter tires are designed for

the conditions that are typical

in those seasons. Audi recom-

mends winter tires during the

winter months. Low tempera-

tures significantly decrease

the elasticity of summer tires,

which affects traction and

braking ability. If summer

tires are used in very cold

temperatures, cracks can form

on the tread bars, resulting in

permanent tire damage that

can cause loud driving noise

and unbalanced tires.

►

Have faulty tires or rims re-

placed immediately.

►

Protect your tires from oil,

grease, and fuel.

►

Mark tires before removing

them so that the same running

direction can be maintained if

they are reinstalled.

►

Lay tires flat when storing and

store them in a cool, dry loca-

tion with as little exposure to

light as possible.

1 Tires for passenger vehicles

(if applicable)

–Burnished, polished, or

chromed rims must not be

used in winter driving condi-

tions. The surface of the rims

does not have sufficient corro-

sion protection for this and

could be permanently dam-

aged by road salt or similar

substances. The exception to

this are rims that are part of

complete winter wheels pro-

vided by the factory.

carefully when doing so.

–Inflation pressure that is too low

or high can increase tire wear

considerably.

–Driving quickly through curves,

rapid acceleration, and heavy

Treadwear indicator

For unidirectional tires, make

sure the tires are installed accord-

ing to the running direction indi-

cated on the tire sidewall

ðpage 302.

Original equipment tires contain

treadwear indicators in the tread

pattern, which are bars that are

1/16 inch (1.6 mm) high and are

spaced evenly around the tire per-

pendicular to the running direc-

tion ðfig. 176. The letters “TWI”

or triangles on the tire sidewall

indicate the location of the tread-

wear indicators.

Hidden damage

Damage to tires and rims can of-

ten occur in locations that are

hidden. Unusual vibrations in the

vehicle or pulling to one side may

indicate that there is tire damage.

Reduce your speed immediately.

Check the tires for damage. If no

damage is visible from the out-

side, drive slowly and carefully to

the nearest authorized Audi deal-

er or authorized Audi Service Fa-

cility to have the vehicle inspect-

ed.

When checking tread depth, you

must check the wear indicators

across the entire width of the tire

and on all four tires.

This can increase the risk of an

accident because it has a nega-

tive effect on handling, driving

through curves, and braking,

and because it increases the

Tires and vehicle load limits

WARNING

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.

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.

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

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 Gross Vehicle Weight Rating

are listed on the safety compli-

ance sticker label located on the

driver’s side B-pillar.

WARNING

Overloading a vehicle can cause

loss of vehicle control, a crash

or other accident, serious per-

sonal injury, and even death.

Steps for Determining Correct

Load Limit

carry will prevent the vehicle

from handling properly and in-

crease the risk of the loss of

vehicle control.

1. Locate the statement “THE

COMBINED WEIGHT OF OCCU-

PANTS AND CARGO SHOULD

NEVER EXCEED XXX KG OR XXX

LBS” on your vehicle’s placard

(tire inflation pressure label)

ðpage 279, fig. 178.

2. Determine the combined

weight of the driver and pas-

sengers that will be riding in

your vehicle.

–The brakes on a vehicle that

has been overloaded may not

be able to stop the vehicle

within a safe distance.

–Tires on a vehicle that has

been overloaded can fail sud-

denly, including a blowout and

sudden deflation, causing loss

of control and a crash.

3. Subtract the combined weight

of the driver and passengers

from “XXX” kilograms or “XXX”

pounds shown on the sticker

ðpage 279, fig. 178.

4. The resulting figure equals the

available amount of cargo and

luggage load capacity. For ex-

ample, if the “XXX” amount

equals 1400 lbs. and there will

be five 150 lbs. passengers in

your vehicle, the amount of

available cargo and luggage

load capacity is 650 lbs.

(1400-750 (5 x 150) = 650

lbs.)

5. Determine the combined

weight of luggage and cargo

being loaded on the vehicle.

That weight may not safely

–Always make sure that the to-

tal load being transported –

including the weight of a trail-

er hitch and the tongue

weight of a loaded trailer –

does not make the vehicle

heavier than the vehicle’s

exceed the available cargo and

luggage load capacity calculat-

ed in Step 4.

Winter tires

6. If your vehicle will be towing a

trailer, load from your trailer

will be transferred to your ve-

hicle. Consult this manual to

determine how this reduces

the available cargo and lug-

gage load capacity of your ve-

hicle.

Winter tires significantly improve the vehicle's

handling when driving in winter conditions. Be-

cause of their construction (width, compound,

tread pattern), summer tires provide less traction

on ice and snow.

►

Use winter tires on all four wheels.

►

Only use winter tires that are approved for your

vehicle.

►

Please note that the maximum permitted

speed may be lower with winter tires ð

in

General information on page 268. An author-

ized Audi dealer or authorized Audi Service Fa-

cility can inform you about the maximum per-

mitted speed for your tires.

►

Check the tire sidewall

(ðpage 269, fig. 175) to deter-

mine the designated load rating

for a specific tire.

►

Check the tire pressure after installing a wheel

ðpage 279.

The effectiveness of winter tires is reduced great-

ly when the tread is worn down to a depth of

0.16 in (4 mm). The characteristics of winter

tires also decrease greatly as the tire ages, re-

gardless of the remaining tread.

Wheel bolts and rims

Wheel bolts

Wheel bolts must be clean and must loosen and

tighten easily.

For the sake of the environment

Rims

Reinstall summer tires at the appropriate

time, because they provide better handling

when roads are free of snow and ice. Summer

tires cause less road noise, tire wear, and fuel

consumption.

Rims with a bolted rim ring* or with bolted wheel

covers* consist of multiple pieces. These compo-

nents were bolted together using special bolts

and a special procedure. You must not repair or

disassemble them ð

.

Tips

WARNING

You can also use all season tires instead of

winter tires. Please note that in some coun-

tries where winter tires are required, only

winter tires with the  symbol may be per-

mitted.

Wheel bolts that are tightened or repaired in-

correctly can become loose and result in loss

of vehicle control, which increases the risk of

an accident. For the correct tightening specifi-

cation, see ðpage 302, Finishing.

– Always keep the wheel bolts and the threads

in the wheel hub clean and free of grease.

– Only use wheel bolts that fit the rim.

Snow chains

Snow chains improve both driving and braking in

winter road conditions.

– Always have damaged rims repaired by an

authorized Audi dealer or authorized Audi

Service Facility. Never repair or disassemble

►

Only install snow chains on the rear wheels.
