General information
Breaking in
A new vehicle must be broken in, and the break­
in distance should be 1,000 mi les ( 1,500 km). Do
not drive at speeds that w ill exceed
2/3 of the
maximum permitted engine speed
(RPM) for the
first 600 miles (1,000 km) , and avoid full accel­
eration 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
higher 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 per iod, part icularly 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 eng ine speeds are automati ­
cally reduced .
Avoid damaging the vehicle
When you are driving on poor roads, or over
curbs, steep ramps, etc., make certain that low­
lying parts such as spoilers and exhaust system
parts do not bottom out and get damaged.
This is especially true for vehicles with low-slung
chassis (sports chassis)* and fully loaded
vehicles.
Driving through water on roads
Note the following to reduce the risk of vehicle
damage when driving through water, for examp le
on flooded roads :
- The wate r must not be any higher than the bot­
tom of the vehicle body .
Driving
- Do not drive faster than walking speed.
A WARNING
After driv ing 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 .
(D Note
Vehicle components such as the engine,
transmission, suspension or electrical system
can be severely damaged by driving through
water.
(D 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 safely.
- Avoid dr iving through salt water, because
this can cause corrosion.
Economical and environmentally-friendly
driving
T he amount of fuel consumpt ion, the environ­
menta l 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 traff ic light is red . .,,.

Ass is t
Assist
Electronic speed Limiter
Your v ehicle may be factory equipped with tires
that are rated for a maximum speed of 130 mph (210 km/h). This is less than the maximum sp eed
of your vehicle . To reduce the risk of sudden tire
failure and loss of control if the vehicle is operat­ ed at excessive speeds, your vehicle also has an
electronic speed limiter . The electronic speed
lim iter prevents your vehicle from going faster
than the t ire speed rating. For mo re information
~ page 253.
If the engine control unit receives faulty vehicle
road speed s ignals , the Malfunction Indicator
L amp (MIL)
¢..ffi will illumina te . If this occurs,
con tact the nearest au thorized A ud i dealer for
assistance.
_& WARNING
Always observe the posted speed limits and
adjust you r speed to suit prevailing road, traf­
fic and weather conditions. Never drive your
vehicle faster than the maximum speed rating
of the tires installed .
Speed warning system
Applies to: vehicles with speed warning system
The speed warning system helps you to stay be­
low a specified maximum speed that can be set,
changed or deleted in the Infotainment system . -
The speed warning system warns you if you are
exceeding the maximum speed that you have set
.
A warni ng tone will sound as soon as you r speed
exceeds the sto red value s lightly . The
(OJ (USA
models)
I [OJ (Canada models) indicator light
and a message appear i n the ins trumen t cluster
d isp lay a t the same time. Th@
Hll (USA models)/
[O](Canada models) i ndicator light and the mes­
sage turn off when the vehicle speed drops be low
the stored maximum speed.
Se tting a threshold is rec om mended if you would
like to be reminded when yo u reach a certa in
maximum speed . Situations where you may want
to do so include driving in a country w it h a ge ne r-
72
al speed limit or if there is a spec ified maximum
speed for winter tires.
Setting the warning threshold
.,. Select in the Infotainment system: IM ENU ! but­

snow and ice. Always read and follow safety pre­
cautions
¢ & .
Winter tires
By using all wheel drive, your vehicle has good
forward motion with standard tires in winter con­
ditions. However, in winter we recommend using
winter or all season tires on
all four wheels, be­
cause this will improve the
broking effect.
Snow chains
If there are snow chain laws, snow chains must
also be used on vehicles with all wheel drive
¢ page 261, Snow chains.
Replacing tires
For vehicles with all wheel drive, only whee ls with
the same rolling circumference should be used .
Avoid using tires with different tread depths
¢ page 2 53, New tires or wheels.
Offroad vehicle?
Your Aud i is not an offroad vehicle - there is not
enough ground clearance. For this reason, avoid
difficult terrain.
_&. WARNING
-Also, in vehicles with all wheel drive, adapt
your driv ing style to the current road and
t ra ffic conditions. Do not let the increased
safety provided tempt you into taking risks,
because this increases the r isk of an acci­
dent.
- The braking ability of your vehicle is limited
to the traction of the wheels. In this way, it
is not different from a two wheel drive vehi­
cle. Do not be tempted to accelerate to a
high speed when the road is slippery, be­
cause this increases the risk of an accident.
- Note that on wet streets, the front wheels
can "hydroplane" if driving at speeds that
are too high. Unlike front whee l drive
vehicles, the eng ine does not rev highe r sud­
denly when the vehicle begins hydroplaning.
For this reason, pay attention to the road
conditions regardless o f your speed.

Rear spoiler
Appl ies to: vehicles with retractable rear spoile r
The extendoble rear spoiler increases driving sta ­
bility.
Fig. 96 Center conso le: button for the rear spoiler
The rear spoiler retracts and extends. It can be
activated in various operat ing modes (manua l
mode or automatic mode).
Automatic mode (normal operation)
- Automatic extension: the rear spoiler w ill auto-
mat ically extend when speeds exceed approxi­
mately 75 mph (120 km/h)
- Automatic retraction: the rear spoiler w ill auto­
matically retract when speeds decrease to un­
der approximately 50 mph (80 km/h).
Manual mode
-Extend ing manually : briefly tap the¢ fig. 96
button to fully extend the rear spoiler .
- Retracting manually: when driving at speeds
below approximately 10 mph (20 km/h), press
and hold the b utton to retract the rear spoiler .
When at speeds be tween 10 mph (20 km/h)
and 75 mph (120 km/h), the rea r spoi ler will
completely retract when you tap the button.
Indicator lights
IJ,. Rear spoiler: malfunction! Please con­
tact Service
The rear spoiler may not have extended due to a
malfunction. This could change the vehicle's driv­
ing characteristics at high speeds. Do not drive
faster than 85 mph (140 km/h) . Drive to an au-
thorized Audi dea ler or authorized Audi Service ..,.

Safe driving
_& WARNING
Heavy loads will influence the way your vehi­
cle handles. To help reduce the risk of a loss
of control leading to serious personal injury:
- Always keep in mind when transporting
heavy objects, that a change in the center of
gravity can also cause changes in vehicle
handling:
- Always distribute the load as evenly as
possible .
- Place heavy objects as far forward in the luggage compartment as possible.
- Never exceed the Gross Axle Weight Rating
or the Gross Vehicle Weight Rating specified
on the safety compliance sticker on the left
door jamb. Exceeding permissible weight
standards can cause the vehicle to slide and hand le differently .
- Please observe information on safe driving
c';> page 181.
_& WARNING
To help prevent poisonous exhaust gas from
being drawn into the vehicle, always keep the
rear lid closed while driving.
- Never transport objects larger than those
fitting completely into the luggage area be­ cause the rear lid cannot be fully closed .
- If you absolutely must drive with the rear lid open, observe the following notes to reduce
the risk of poisoning:
- Close all windows,
- Close the convertible top,
- Open all air outlets in the instrument pan-
el,
- Switch off the air recirculation,
- Set the fresh air fan to the highest speed .
_& WARNING
'
-
Always make sure that the doors, all win­
dows, the convertible top and the rear lid are
securely closed and locked to reduce the risk
of injury when the vehicle is not being used.
- After closing the rear lid, always make sure
that it is properly closed and locked.
186 -
Never leave your vehicle unattended espe­
cially with the rear lid left open. A child
could crawl into the vehicle through the lug­
gage compartment and close the rear lid be­
coming trapped and unable to get out . Be­
ing trapped in a vehicle can lead to serious
personal injury.
- Never let children play in or around the vehi­
cle.
- Never let passengers ride in the luggage compartment . Vehicle occupants must al­
ways be properly restrained in one of the ve­ hicle 's seating positions.
{1) Tips
- Air circulation helps to reduce window fog­
ging . Stale air escapes to the outside
through vents in the trim panel, on the left
side of the luggage compartment. Be sure
to keep these slots free and open.
- The tire pressure must correspond to the
load. The tire pressure is shown on the tire
pressure label. The tire pressure label is lo­
cated on the driver's side B-pillar. The tire
pressure label lists the recommended cold
tire inflation pressures for the vehicle at its
maximum capacity weight and the tires that
were on your vehicle at the time it was man­ ufactured. For recommended tire pressures
for normal load conditions, please see chap­
ter
c';> page 257.
Tie -downs
The luggage compartment is equipped with four
tie-downs to secure luggage and other items .

General information
.,. Check your tires regularly for
damage (punctures, cuts, cracks
and bulges). Remove foreign ob ­
jects from the tire tread.
.,. If driving over curbs or similar
obstacles, drive slowly and ap­ proach the curb at an angle.
.,.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 location
with as little exposure to light as
possible.
(D N ote
-Please note that summer and
winter tires are designed for
the conditions that are typical in those seasons . Audi recom­
mends using winter tires dur­
ing the winter months . Low
temperatures significantly de­ crease the elasticity of summ­
er tires, which affects traction
2 4 6
and b raking 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.
-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.
