General information
Breaking in
A new vehicle must be broken in for the first 1,000 mi les (1,500 km). Do not drive at speeds
that will exceed 2/3 of the maximum perm itted
engine speed (RPM) for the first 600 miles
(1,000 km), and avoid full acceleration during
this period . You may gradually start increasing
the RPM and the speed between 600 miles (1,000 km) and 1,000 miles (1,500 km) .
During the first hours of use, the engine has a
h igher internal friction than later on when all
moving parts have settled into place with each
other.
How the vehicle is driven during the first 1,000
miles (1,500 km) also affects the engine quality.
Drive at moderate engine speeds after the initial
break-in period, particularly when running a cold
engine. This will reduce engine wear and improve
the mileage .
Do not drive at too low of an engine speed (RPM) .
Shift down if the engine stops running "smooth­ ly". Extremely high engine speeds are automati­
cally reduced .
Reducing the risk of vehicle damage
(D Note
When driving on poor roads, by curbs and on
steep ramps, make su re that low-hang ing
components such as the spoi ler and exhaust
system do not come into contact with these
or they could be damaged. This especially ap­
plies to vehicles with low ground clearance
and vehicles that are heavily loaded.
Driving through water on roads
Note the following to reduce the risk of vehicle
damage when driv ing through water, for example
on flooded roads:
-The water must not be any higher than the bot­
tom of the vehicle body .
80
-Do not drive faster than walking speed .
A WARNING
After driving through water or mud, the effec­
tiveness of the brakes may be reduced due to
moisture on the brake rotors and brake pads.
A few careful brake applications should dry
off the brakes and restore the full braking ef­
fect .
{CT) Note
-Vehicle components such as the engine,
transmission, suspension or electrical sys-
tem can be severely damaged by driving
through water .
-Always switch the Start/Stop system* off
when driving through water <=:>page
85.
@ Tips
-Determine the depth before driving through
water.
-Do not stop the vehicle, drive in reverse or
switch the engine off when driving through
water .
'
-Keep in mind that oncoming vehicles may
create waves that raise the water level and
make it too deep for your vehicle to drive
through safe ly .
-Avoid driving through salt water, because
this can cause corrosion .
Economical and environmentally -friendly
dr iving
The amount of fuel consumption, the environ­
mental impact and the wear to the engine,
brakes and tires depends mostly on your driving
style. With an anticipatory and economic driving
style, fuel consumption can be reduced by ap­ proximately 10-15%. The following tips will help
you conserve the environment and your money at the same time .
Anticipatory driving
A vehicle uses the most fuel when accelerating.
When you drive with anticipation, you do not need to brake as often and so you accelerate less.
When possible, let your vehicle coast with a gear
..,.

engaged, for example when you notice that the next traffic light is red . This produces an engine
braking effect, which helps to protect the brakes
and tires and reduces the emissions and fuel con ­
sumpt ion to zero (fuel shut-off dur ing decelera­
tion) .
Shift efficiently
Upshifting earlier is an effective way to save fuel.
Staying in a gear too long uses fuel unnecessari­
ly.
Applies to: vehicles with manual transmission
Shift as soon as possible from first to second
gear. S hifting to the next highest gear at approxi­
mately 2,000 RPMs if poss ible is recommended.
Applies to: vehicles with automatic transmissions
Press down on the acce le rator peda l slowly and
avoid "kick -down".
Avoid full acceleration
You should rarely travel at the maximum vehicle
speed. High speeds cause a disproportionately
high increase in fuel consumption, emissions and
traffic noise. Driving more slowly saves fuel.
Reduce idling time
The Start/Stop system* he lps to reduce the idling
time automatically. In vehicles without the Start/
Stop system*, it is efficient to switch the engine
off when stopped at railroad cross ings and long
r ed lights. Stopping the engine for 30-40 sec­
onds already saves more fuel than the amount of
extra fuel needed to restart the eng ine.
It takes a very long time in idle to warm the en­
g ine up to operating temperature. Wear and
emissions are especially h igh in the wa rm-up
phase . Therefore, you should begi n driving im­
mediately a fter starting the engine . Avoid high
RPMs while do ing this .
Have maintenance performed regularly
By having maintenance performed regu larly on
your veh icle, yo u ca n he lp to reduce f uel con­
sumption before yo u even start to drive. The
maintenance condition of your vehicle not only
affects traffic safety and long-term value but a l-
Driving
so impacts fuel consumption . A poorly main ­
tained engine can lead to fuel consumption that is 10% higher than norma l.
Avoid short trips
The eng ine and exhaust cleaning system must
reach their optimal operat ing temperatu re to ef­
f ectively reduce consumption and emissions.
A cold engine uses a disproportionately high
amount of fue l. The engine reaches operating
temperat ure and consumption normalizes on ly
after approximate ly 2.5 miles (4 km).
Check the tire pressure
To save fuel, make sure the tires are always in­
flated to the correct press ure
~ page 344. The
fuel consumption can increase by 5% if the pres­
s u re is only 0.5 bar too low. Due to the increased
rolling resistance, low tire pressures wi ll also
l ead to greater tire wear and will affect driving
behavior.
Do not drive on winter tires year-round, as this
will consume up to 10% more fuel.
Eliminate unnecessary weight
S in ce eve ry po und of ext ra weight increases f uel
consumption , a quick inspection of the luggage
compartment may be worth it to avoid unneces ­
sary weight .
When not be ing used , a roof rack should be re­
moved to decrease the wind resistance of the ve­
hicle. This will save you approximately 12% fuel
at speeds from 62 -75 mph (100 - 120 km/h) .
Save energy
The eng ine drives the generator, which generates
electric ity; the fuel consumpt io n also incr eases
with the demand for electr icity. The refore, switch
electrical eq uipment off when you no longer
need it . Examples of equipment that uses a lo t of
energy are air blowers at a high setting, the rear
window defogger and seat heating* .
@ Note
Do not leave engine idling unattended after
starting. If warning lights shou ld come on to
indicate improper operation, they would go

(D Note
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.

" 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.

-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.

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

the risk of a n acc ident beca use it can cause
the tire to burst.
- Always adapt your driving to the road and
traff ic conditions. Drive carefully and red uce
yo ur speed on icy or slippery roads. Even
winter tires can lose traction on b lack ice.
@ For the sake of the environment
Reinstall summe r tires at the approp riate
time, because they provide better hand ling
when roads are free of snow and ice. S ummer
tires cause less road noise, tire wear and fuel
consumption.
(D Tips
You can also use all season tires instead of
w inter t ires. Please note that in some coun­
tries w here w inte r ti res are req uired, only
w inter t ires with the
& symbol may be per ­
m itted.
Snow chains
Snow ch ains not only i mprove the d riving in win ­
t er ro ad cond itions, b ut also the brak ing.
... Only insta ll snow chains o n the front wheels .
T h is applies also to ve hicles w ith all wheel
drive* .
... Check an d cor rect the sea ting of the snow
c h ains a fte r dr iv ing a few feet, i f necessary. Fo l­
l ow the instructions from the manufacturer .
... Note the maximum permitted speed when d riv ­
ing with snow chains . Do not exceed 30 mp h
(SO km/h).
Use of snow chains is on ly pe rmitted with certain
rim/t ire combinations due to technical reasons.
Check with an authorized Audi dealer o r autho r­
ized Aud i Service Fac ility to see if yo u may use
snow chains.
Use
fine -mesh snow chains . They must not add
more t han 0.53 in (13.5 mm) in height, includ ing
the chain lock .
You must remove the snow c hains on roads wit h­
out snow. Othe rw ise, you could impa ir dr iv ing
ab ility and damage the tires.

A WARNING ~
Using incorrect snow chains or installing snow
cha ins i ncor rectly can result in loss of veh icle
con trol, which increases the risk of a n acci­
d ent.
(D Note
Snow chains can damage the rims/whee l cov­
e rs* if the chains come into direct contact
wi th them . Remove the whee l covers* first.

Low-profile tires
Applies to: vehicles with low-profile tires
Your vehicle is equip ped wi th low -profi le t ires* at
t h e factory. Compa re d t o o ther tire/r im com bina ­
tions, low -profi le tires offer a w ider tread surface
and a larger rim diameter with shorter tire side­
walls . This results in an agile dr iv ing style. How­
ever, it may reduce the leve l of com fort and in­
crease road noise whe n driving on roads in poor
cond it ion.
Low-p rofile ti res can become damaged mo re
q uick ly than standard tires when dr iv ing ove r
l a rge bumps, potholes, manhole covers, speed
bumps and curbs . Therefore, it is particularly im­
po rtan t to maintain the correct tire pressure
<:;> page 344.
To reduce the risk of damage to the tires and
rims, drive very caref ully on poor roads.
Check your wheels regu larly eve ry 2,000 mi
(3,000 km) for damage. For example, check for
bulges/cracks on the tires or deformations/
cracks on the rims .
After a heavy impact o r damage, have the tires
and rims inspected or replaced immediately by
an authorized Audi dea ler or authorized Audi
Service Facility .
