Driving information
Applies to: vehicles with offroad mode
T here is only one right way to drive in difficult
conditions: slo wly and with caution!
Observe the following when driving on unpaved
roads :
.,. On ly driv e in terrain that is suitable for the ve­
hicle and your driving ability. Never take any
unnecessary risks!
.,. Dr ive slowly and caut iously!
.,. Pay attent ion to the
g round cl earan ce of your
veh icle . The clearance may va ry depending on
the load, ground compos ition and the environ­
ment. The g round clearance is reduced for spe­
cial suspension systems, such as sport s uspen­
sion. The dr iver is therefore responsible for de ­
ciding whether a vehicle can handle a specif ic
situation .
.,. Activate the
ESC offroad mode as needed
r=>page90 .
.,. Use the hill de sce nt ass ist when driving down
steep hills
r=> page 91 .
Difficult terrain
When driving in unfamiliar areas and offroad,
drive slowly and keep on the watch for unexpect­
ed obstacles (such as potholes, rocks, tree
stumps , etc .) .
T o prevent th e vehicl e from bottoming out and to
reduce the risk of underbody damage, you should
drive across uneven ground on only one side of
the veh icle so that only two of your wheels cross
the uneven area, instead of driving across the cente r of the uneven area with all four wheels .
Drive quickly through sandy or marshy off-ro ad
sections and do not stop, if at all possible.

Intelligent Technology
-Press the accelerator pedal carefully when
accelerating on even, slippery surfaces such
as ice and snow. The drive wheels can spin
even when these control systems are instal­
led and this can affect driving stability and
increase the risk of a collision.
{D) Tips
-The ABS and ASR only function correctly

The following examples are unusual situations
where it may make sense to switch offroad mode
on to allow the wheels to spin:
- Rocking the vehicle to free it when it is stuck
- Driving in deep snow or on loose ground
- Driv ing on rough terrain when much of the car's
we ight is lifted off the wheels (axle artic ula­
tion)
- Dr iv ing downh ill wh ile braking on loose g round
The ESC is designed to function in levels. Depend­

dea ler o r autho rized Aud i Serv ice Facility fo r as ­
sis tance.
If the indicator light turns on, the steering wheel may be more diff icult to move or more sensitive
than usual. The steering wheel may also be at an
angle when dr iving straight .
Drive s low ly to an author ized Audi dealer or au­
thor ized Audi Se rvice Fac ility to have the mal­
function co rrected.
kr-ij Steering lock: System fault ! Please contact
dealer.
There is a malfunction in the electronic steering
l ock.
Drive to an authorized Aud i dea ler o r aut horized
Audi Service Facility immediately to have the
malfunction corrected.
A WARNING
-
Have the system malfunction corrected as
soon as possible by an author ized Audi dealer
or authorized Aud i Service Fac ility, as this in­
creases the risk of a n accident .
(D Tips
If the . or i1:.ij indicator light only stays on
for a short time, you may continue dr iv ing.
Intellig ent Technology
All wheel drive (quattro)
Applies to: vehicles with all wheel drive
In all wheel drive, all four wheels are powered.
General information
In all whee l drive, the dr iving power is div ided be­
tween all fou r wheels . This happens automatical­
ly depending on yo ur driving behavior as we ll as
the cur rent road conditions . A lso see ¢
page 89 .
The all whee l dr ive concept is des igned for high
engine power. Yo ur vehicle is except iona lly pow­
erfu l and has excellent driving characteristics
both under normal driving conditions and on
snow and ice. Always read and follow safety pre­ cautions
q .&, .
Winter ti res
By using all whee l drive, your veh icle has good
forward motion w ith standard tires in winter con­
ditions . However, using winter or all season tires
on
all four wheels in the winter is recommended,
because th is w ill improve the
braking effect.
Snow chains
If there a re snow chain laws, snow cha ins m ust
also be used on ve hicles with all wheel drive
¢ page 181, Snow chains .
Replacing tires
For vehicle s wi th a ll wheel d rive, o nly wheels wi th
the same roll ing ci rcumfe rence sho uld be used.
Avoid using tires with di fferen t tread depths
¢ page 173, New tires or wheels.
A WARNING
- Also, in vehicles with all whee l drive, adapt
your driving style to the current road and traffic cond itions. Do not let the increased
safety prov ided tempt you into taking r isks,
because this increases the risk of an acc i­
dent.
- The braking ab ility of your vehicle is limited
to the trac tion of the wheels. I n this way, it
is not different from a two w heel d rive vehi ­
cle. Do no t be tempte d to accelerate to a
h igh speed when the ro ad is s lippery, be -
cause t his increases t he risk of an acci den t. ...,

What impairs driving safety?
Safe driving is directly related to the condition of
the vehicle , the driver as well as the driver's abili­
ty to concentrate on the road without being dis­
tracted.
The driver is responsible for the safety of the ve­
hicle and all of its occupants. If your ability to
drive is impaired, safety risks for everybody in the
vehicle increase and you also become a hazard to
everyone else on the road
¢ _&. . Therefore:
.. Do not let yourself be distracted by passengers
or by using a cellular telephone .
.. NEVER drive when your driving ability is im­
paired (by med ications, alcohol, drugs, etc .) .
.. Observe all traffic laws, rules of the road and
speed limits and plain common sense . .,.

Using the prope r engine oil is important for the
functionality and s ervice life of the engine. Your
engine was factory-filled with a high -quality oil
which can usually be used throughout the entire
year .
Note
Your Limited New Vehicle Warranty does not
cover damage or malfunctions due to failure
to follow recommended maintenance and use
requirements as set forth in the Audi Owner's Manual and Warranty & Maintenance booklet .
- Use only a high quality engine oil that ex-
pressly complies with the Aud i oil quality
standard specified for your vehicle's engine.
Using any o ther oil can cause serious engine
damage.
- Do not mix any lubricants o r other additives
into the engine oil. Doing so can cause en­
gine damage.
@ Tips
If you need to add oil and there is none availa­
ble that meets the Audi o il quality standard
your eng ine requ ires, you may add a total of
no more than 0 .5 quart/li ter of a h igh-quality
"synthet ic"oil that meets the following speci ­
fications.
- ACEA A3 or API SM with a v iscosity grade o f
SAE OW-30, SAE SW -30 or SAE SW-40.
- Fo r more information abou t engine o il t ha t
has been approved for your vehicle, please

www .audiusa.com or www .aud icanada .ca.
Engine oil consumption
T he engine in your vehicle depends on an ade­
qua te amoun t of oil to lubricate and cool all of
i t s moving par ts.
In order to provide effective lub rication and coo l­
ing of in te rnal engine components, a ll internal
combustion engines consume a cer tain amount
of oil. Oil consumption varies from engine to en ­
g ine and may change sign ificantly over the life of
the eng ine . Typically, eng ines with a spec ified
Ch eck ing and Filling
break-in period (see ¢ page 57) consume more
oi l during th e break-in period than they consume
after oil consumption has stabilized.
Under normal cond itions, the rate of oil con­
sumption depends on the q uality and viscos ity o f
the oil , the RPM (revolutions per minut e) at
which the engine is operated, the amb ient tem­
perature and road condit ions. Further factors are
the amount of oil dilution from w ater condensa­
tion or fuel resid ue and the oxidation level of the
o il. As any engine is subject to wear as mileage
builds up, the oi l consumption may increase ove r
t ime unt il repla cement of worn components may
become necessary.
With al l these variables coming into play, no
standard rate of o il consumption can be estab­
l ished or spec ified . T he re is no alte rnative to reg­
u la r and fre quent chec king of the o il level , see
Note .
If the yellow engine oil level warning symbo l II
in the instrument cluster lights up , you sho uld
check the o il level as soon as possible
¢ page 160. Top off the o il at your earliest con­
venience.
A WARNING
Before you check anything in the engine com­
partment, always read and heed all WARN ­
INGS¢ .&.
in Working in the engine compart­
ment on page 155.
(D Note
D riving wit h an insufficient oil level is likely to
cause severe damage to the engine .
(D Tips
- The oil pressure warn ing display. i s not
an indicato r of the o il le vel. Do not rely on
it . Instead, check the oil level in your en ­
gine at regular intervals , pre fe rabl y each
time you refuel, and alw ays befo re go ing
on a long trip .
-If you have the impression your engine con­
sumes excessive amounts of oi l, we recom­
mend that you consult an author ized Audi
dea ler to have the cause of your concern

The tire pressures must be stored in the Infotain­
ment system again each time the pressures
change (switch ing between partial and full load
pressure) or after changing or replacing a tire on
your vehicle
c:::> page 184. The tire pressure moni­
toring system only monitors the tire pressure you have stored . Refer to the tire pressure label for
the recommended tire pressure for your vehicle
c:::> page 176, fig. 147.
Tire tread circumference and vibration character­ istics can change and cause a t ire pressure warn­
ing if:
- the tire pressure in one or more tires is too low
- the tire has structural damage
- the tire was replaced or the tire pressure was
changed and it was not stored

Replacing light bulbs
For your safety, we recommend that you have
your authorized Audi dealer replace any bulbs for
you .
It is becoming increasingly more and more diffi­
cult to replace vehicle light bulbs since in many
cases, other parts of the car must first be re­
moved before you are able to get to the bulb .
T his applies especially to the light bulbs in the
front of your car which you can only reach
through the engine compartment .
Sheet metal and bu lb holders can have sharp
edges that can cause serious cuts, pa rts must be
correctly taken apart and then properly put back
together to help prevent breakage o f parts and
long term damage from water that can enter
housings that have not been properly resealed.
For your safety, we recommend that you have
your authorized Aud i dea ler rep lace any bulbs fo r
you, since your dealer has the proper tools, the
correct bulbs and the expertise.
Gas di schar ge la mps (Xe no n ligh ts):
Due to the high electr ical voltage, have the bulbs
rep laced by a qualified technician. Headlights
with Xenon light are identified by the hig h volt­
age st icker.
LED headlights* require no maintenance . Please
contact your authorized Audi dea ler if a bulb
needs to be replaced.
_&. WARNING
Changing Xenon lamps wi thout the necessary
equipment can cause serious personal injury .
- Bulbs are pressu rized and can explode when
be ing changed. Potent ial ris k of injury!
- On veh icles equipped with gas disc harge
bu lbs (Xenon light) life-threatening injuries
can resu lt from improper handling of the
high-vo ltage portions of such lamps!
- Only your authorized A udi dealer or quali­
f ied workshop sho uld change the bulbs in
gas discharge lamps. There are parts with
sharp edges on the openings and on the
