\.J ' Driving
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 .
New tires
If your vehicle is running on new tires, drive pa r­
ticularly careful for the first 350 miles (500 kilo­
meters) after fitting .
.&_ WARNING
-
New tires tend to be slippery and must also
be "broken-in". Be sure to remember this dur­
ing the first 350 miles (500 kilometers).
Brake gently . Avo id following closely behind
other vehicles or other situations that might
require sudden, hard brak ing.
Avoid damaging the vehicle
When you are driving on poor roads, or over
curbs, steep ramps, etc., make certain that low-
D riving
lying parts such as spoilers and exhaust system
parts do not bottom out and get damaged .
T h is is espec ially true for veh icles with low-slung
chass is (sports chassis)* and fully loaded
vehicles.
Warming up/cooling down
Appl ies to: Sand RS models
By warming up/cooling down the engine careful­
ly, you can he lp reduce unnecessary strain on
your vehicle when driving in a sporty style.
The engine speed is limited when the engine is
cold -the full engine output is not available.
When the engine is at operat ing temperature,
the engine speed limitation moves to a higher
RPM range. The tires also only reach their full
road holding capab ility once they have warmed
up .
Your vehicle also has an after-run cooling fea­
ture . However, cooling down is still important.
The engine and the brakes as well as the exhaust
system and the transmission become very hot
when driving in a spo rty style . Before you shut
the vehicle off, you should cool down the vehicle
by driving a few miles at low speeds with light ac­
celeration.
Driving through water on roads
Note the following to reduce the risk of vehicle
damage when driving through water, for example
on flooded roads:
- The water must not be any higher than the bot­
tom of the vehicle body .
- Do not drive faste r than walking speed.
.&_ 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 .
(D Note

- Do not s to p the veh icle, dr ive in reverse or
swi tc h t he eng ine off when dr iv ing t hrough

Economical and environmentally-friendly
driving
The amount of fue l cons umption, the env iron­
men tal impact and the wear to the engine,
b rakes and t ires dep ends mostly on your dr iv ing
style. W ith an anticipatory and economic driv ing
s tyle, f ue l consumption can be reduced by ap­
p roximate ly 10-15% . The following tips will help
you conserve the environment and your money at
the same time .
Anticipatory dr iving
A veh icle uses the mos t fu el when a cce le ra ting.
W hen you dr ive wi th ant icipat ion, you do not
need to brake as often and so you ac celerate less .
When possib le, let your ve hicle coast wit h 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 a nd fuel con­
sumpt io n to ze ro (f uel shut-off dur ing decelera­
tion) .
Shift efficiently
An effective way to save fuel is to upshift earlier.
Staying in a gear too long uses fue l unnecessari­
ly .
Press down on the acce le rator peda l slowly and
avoid "k ick -down" .
66
Avoid full acceleration
You should rarely travel at the maxim um vehicle
speed. Hig h speeds cause a disproportionate ly
high increase in fue l cons umption, emissions and
traffic noise. Slowe r driving saves fue l.
Reduce idling time
The Start-S top system * helps to re du ce the idling
time automat ic all y. In ve hicles withou t the Star t­
Stop system *, i t is efficient to sw itch the engine
off when stopped at railroad crossings and long
red lights. Stopping the engine for 30-40 sec­
onds a lready saves more fue l than the amo unt of
extra fue l needed to restart the engine.
It takes a very long time in id le to warm the en­
gine up to operating temperature. Wear and
emissions are especially high in the warm- up
phase . Therefore, you shou ld begin driving im­
med iate ly after starting the engi ne. Avoid high
RPMs wh ile doing this.
Have maintenance performed regul arly
By having maintenance pe rformed reg ula rly on
your vehicle, you can help to reduce fuel con­
sumption before you even start to drive. The
mainte nance condition of your vehicle not on ly
affects traffic safety and long- term value but al­
so im pacts
fuel consumption . A poorly main­
ta ined engine can lead to fuel consump tio n t hat
i s 1 0% hig he r th an no rm al.
Avoid short trips
The eng ine and exhaust clean ing system must
r each their op tima l
operating temperature to ef­
fect ively reduce consump tion a nd emissions.
A cold engine uses a d isproportionately high
amount of fuel. T he eng ine reaches operat ing
temperat ure and cons umption no rma lizes only
af ter approximate ly
2.5 miles (4 km).
Check the tire pressu re
To save fue l, make sure the t ires are always in­
flated to t he correct press ure
r=':>page 221. The
fuel consumpt ion can increase by 5% if the pres­
s ur e is only 0 .5 bar too low . Due to t he i ncreased
r oll ing resis tance, low tire p ressures w ill also

lead to greater tire wear and will affect driving
behav ior.
Do not drive on
winter tires year-round , as this
will consume up to 10% more fuel.
Eliminate unnecessary weight
Since every kilogram of extra weight increases
fuel consumption, a quick inspection of the lug­
gage compartment may be worth it to avoid un­
necessary weight.
When not being used, a roof rack should be re­ moved to decrease the wind resistance of the ve­
hicle. You will save approximately 12% of your
fuel when at speeds from 62-75 mph (100-120 km/h).
Save energy
The engine drives the generator, which generates
electricity; the fuel consumption also increases
with the demand for electricity. Therefore, switch
electrical equipment off when you no longer
need it. Examples of equipment that uses a lot of
energy are air blowers at a high setting, the rear
window defogger and seat heating*.
CD Note
Do not leave engine idling unattended after
starting. If warning lights should come on to
indicate improper operation, they would go
unheeded. Extended idling also produces
heat, which could result in overheating or
other damage to the vehicle or other proper­
ty .
CD Note
-Have your vehicle maintained properly and
in accordance with the service recommenda­
tions in your Warranty
& Maintenance book ­
let. Lack of proper maintenance as well as
improper use of the vehicle will impair the
function of the emission control system and
could lead to damage .
- Do not alter or remove any component of
the Emission Control System unless ap­
proved by the manufacturer.
- Do not alter or remove any device, such as
heat shields, switches, ignition wires,
Driving
valves , which are designed to protect your
vehicle's Emission Control System and other
important vehicle components.
(D Tips
The consumption estimates as published by
ENVIRONMENTAL PROTECTION AGENCY
(EPA) and Transport Canada may not corre­
spond to your actual consumption on the
road, which will vary depending upon vehicle
load and speed, road and weather conditions,
trip length, etc .
Steering
Manual steering wheel position adjustment
Applies to: vehicles with manual steering wheel adjustment
The steering wheel position is adjustable up and
down and forward and back.

\.J ' Tire pressure
When towing a trailer, inflate the tires of your
vehicle to the tire pressure listed under "Full
load" on the label
¢page 221. Inflate trailer
tires to trailer and tire manufacturers' specifica­
tions .
Lights
Check to make sure both vehicle and trailer lights
are working properly.
Safety chains
Be sure trailer safety chains are properly connect­
ed from the trailer to the hitch on the vehicle. Leave enough slack in the chains to permit turn­
ing corners. When you install safety chains, make
sure they will not drag on the road when you are
driving.
The chains should cross under the trailer tongue
to prevent it from dropping in case of separation
from the hitch.
Adjusting the Audi drive select
Make sure the vehicle is on a level surface before
hitching up the trailer and before adjusting the
tongue weight. The vehicle must be in
auto or
comfort driving mode and not raised
¢page 105, ¢0 .
Make sure that the vehicle is lowered. In Info­
tainment , select:
ICARI function button> Lower
control button.
If you must drive under poor road conditions , you
can raise the vehicle
after coupling the trailer or
after adjusting the tongue weight ¢page 107.
0 Note
-Changes in temperature or load can affect
the height of the vehicle.
- Always select
auto or comfort mode. Other­
wise, the tongue load specified for your ve­
hicle will no longer be applicable.
Trailer towing
Driving instructions
Driving with a trailer always requires extra care
and consideration .
Weight distribution
Towing a loaded trailer with an empty car results
in a highly unstable distribution of weight. If this
cannot be avoided, drive at very low speeds only
to avoid the risk of losing steering control.
A "balanced" rig is easier to operate and control.
This means that the tow vehicle should be loaded
to the extent possible and permissible, while keeping the trailer as light as possible under the
circumstances . Whenever possible, transfer
some cargo to the luggage compartment of the
tow vehicle while observing tongue load require­
ments and vehicle loading considerations.
Speed
The higher the speed, the more difficult it be­
comes for the driver to control the rig . Do not
drive at the maximum permissible speed. Reduce
your speed even more if load, weather or wind
conditions are unfavorable -particularly when
going downhill.
Reduce vehicle speed
immediately if the trailer
shows the slightest sign of swaying .
Do not try
to stop the swaying by accelerating.
Observe speed limits. In some areas, speeds for
vehicles towing trailers are lower than for regular
vehicles.
Always apply brakes early . When driving down ­
hill, shift into a lower gear to use the engine
braking effect to slow the vehicle. Use of the
brakes alone can cause them to overheat and fail.
Air suspension*
When driving with a trailer, activate the trailer
mode of the air suspension. Switch the air sus ­
pension trailer mode on when you are towing a
trailer. This will limit the regulation by the air
suspension while driving . Select in the MMI:

Assist Speed warning system
Applies to: vehicles with speed warning system
The speed warning system helps you to stay un­
der a specified maximum speed.
The speed warning system warns you if you are
exceeding the maximum speed that you have set.
A warning tone will sound as soon as your speed
exceeds the stored value slightly.
The . (USA models)/ . (Canada models) indi­
cator light and a message appear in the instru­
ment cluster display at the same time. The./
• indicator light and the message turn off if the
speed falls back below the stored maximum
speed .
Setting a threshold is recommended if you would
like to be reminded when you reach a certain
maximum speed. Situations where you may want
to do so include driving in a country with a gener­
al speed limit or if there is a specified maximum
speed for winter tires.
Setting the warning threshold
The warning threshold is set in the Infotainment
system.
.. Select: the
ICARI function button > (Car)* Sys­
tems control button > Driver assistance >
Speed warning.
@ Tips
Regardless of the speed warning system, you
should always monitor your speed using the
speedometer and make sure you are following
the legal speed limit.
Assist
Cruise control system

The speed is maintained by modifying engine
power or through an active brake intervention.
A WARNING
-Always pay attention to the traffic around
you when the cruise control system is in op­
eration . You are always responsible for your
speed and the distance between your vehi­
cle and other vehicles.
- For safety reasons, cruise control should not
be used in the city, in stop-and-go traffic, on
winding roads and when road conditions are poor (such as ice, fog, gravel, heavy ra in and
hydroplaning), because this inc reases the
risk of an accident.
- Switch the cruise control off temporarily

depending on the s ituation. The distr ibution of
power varies from balanced (comfort) to sporty
(dynamic) depending on the selected mode. The
goal is a high leve l of agility and ability to accel­
erate on curves. The veh icle is very responsive to
steer ing .
Cornering light*
The cornering light adapts the high beams to the
direction of the curve depending on the speed.
The pivot ing action and the lighting also adapt to
the mode.
Adaptive c ru ise contr ol*
The behavior when acce le rating can be adjusted
from comfortable to sporty, depending on the
drive select mode. Adaptive cruise control a lso
responds to the driving behavior of the veh icle
ahead in a more conservative or sporty manner.
Engine sound *
The engine sound adapts to the current mode
and can be subtle to sporty .
(D Note
Applies to: vehicles with adaptive air suspension
- Make sure there is enough clearance above
and below the veh icle when parking. The
height of the vehicle (ground clearance) can
change once it is parked due to tempera ture
fluctuations, changes to the load condit ions
and c hanges to the d riving modes.
- When transporting the veh icle on a car car­
r ier, tra in, ship or by other means, only tie
the veh icle dow n at the running surfa ce of
the tires, w hic h is the outer circ umference .
Securing the vehicle at the axle compo ­
nents, suspension st ruts or towing eyes is
not permitted because the pressure in the
air suspension struts can change dur ing
transport . The vehicle may not be secured
sufficiently if this happens.
(D Tips
- In some models, the maximum vehicle
speed can only be reached in the auto and
dynam ic modes.
106
- The S se lector lever position a utomat ica lly
engages if the dynamic mode is selected.
- Applies to: vehicles with dynamic steering:
operating noise is heard when starting or
stopp ing the engine. Th is does not indicate
a problem.

you into taking risks. This could increase
your risk of a collision.
- Please note the risk of a co llision increases
when driving fast, especially through curves
and on slippery or wet roads, and when driv­
ing too close to objects ahead. The ESC and
its integrated systems cannot always pre­
vent collisions -there is still a r isk of acci­
dents!
- 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
- ABS and ASR only function correctly when
all four wheels are equipped with identical
tires. Different tire s izes can lead to a reduc­
tion in engine power.
- You may hear noises when the systems de­
scribed are working.
ESC turns on automatically when you start the engine .

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 braking effect.
Snow chains
If there are snow chain laws, snow chains must
also be used on vehicles with all wheel drive
¢ page 227, Snow chains.
Replacing tires
For vehicles w ith all whee l dr ive, only whee ls w ith
the same rolling circumference should be used .
Avoid using tires with different tread depths
¢ page 218, New tires or wheels.
Offroad vehicle?
Your Audi is not an offroad vehicle -there is not
enough ground clearance. For this reason, avoid
difficult terrain.
_& WARNING
-Also, in vehicles with a ll wheel drive, adapt
your dr iving style to the current road and
traff ic conditions. Do not let the increased
safety provided tempt you into taking risks,
because this increases the risk 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 dr ive 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 wheel drive
vehicles, the engine does not rev higher sud­
denly when the vehicle begins hydroplaning .
For this reason, adapt your speed to the
road conditions to reduce the risk of an acci­
dent.

Rear spoiler
The extendable rear spoiler increases driving sta­
bility.
Fig. 141 Center console: button for the rear spoiler
T he rear spo iler retracts and extends. Var ious op­
erating modes (automatic o r manua l mode) can
be activated .
Automatic mode (normal operation)
-Extends automatically: when the vehicle speed
exceeds approx imately 80 mph (130 km/h) .
- Retracts automat ically: when the vehicle speed
drops below approx imately SO mph (80 km/h).
Manual mode
- Extending manually: briefly tap the button to
fully extend the rear spoiler.
- Retracting manually: when driving at speeds
below approximately 10 mph (20 km/h), press
and hold the button to retract the rear spoiler.
When at speeds between 10 mph (20 km/h)
and 80 mph (130 km/h), the rear spoiler will
completely retract when you tap the button.
Indicator lights
lfa /. Rear spoiler: System fault!
The rear spoiler may not have extended due to a
malfunction . This cou ld 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 dealer or authorized Audi Service Facility immed iately to have the malfunction cor ­
rected . The color of the indicator light depends
on the vehicle speed .

Wheels and Tires
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.
.,.M ark 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 Note
-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
Wheels
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.
-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.
