(1) Note
Never drive with the tan k completely emp­
ty. An irregu la r fuel supp ly can ca use the
eng ine to misfire. This leads to uncom­
busted fuel in the exhaust system. This
can cause overheating and damage to the
catalyt ic converter.
Engine coolant temperature gauge
The engine coolant temperature gauge@
¢
page 10 , fig . 3 only functions when the ig­
n ition is switched on . To prevent engine dam ­
age, observe the follow ing important points
concerning the temperature ranges.
Cold r ange
If only the LEDs at the bottom of the gauge
turn on, the engine has not reached operat ing
temperature yet . Avoid high eng ine speed, full
throttle, and heavy eng ine load.
Norm al ra nge
The engine has reached its operating temper­
ature once the LEDs up to the center of the
gauge turn on under normal driving condi­
tions . The LEDs higher up may turn on when
the eng ine is under heavy load or the exter ior
temperature is high . Thi s is not a cause for
concern as long as the. indicator light in
the disp lay does not turn on .
Hot range
If the LEDs in the upper area of the display
and the. indicator light in the instrument
cluster display turn on, the coolant tempera­
ture is too h igh ¢
page 20.
A WARNING
-Always observe the warn ing in
¢
page 210 before opening the hood
a nd checking the engine coolant level.
- Never open the eng ine hood if you see or
hear steam, or if you see engine coolant
dripping from the engine compartment .
You could bur n yourself. Let the engine
coo l off first u ntil yo u can no longer see
or hear steam or coolant escaping.
([) Note
-Add itional headlights and other compo­
nents in front of the a ir intake reduces
affect of the eff iciency of the coolant. At
hig h ou tside air temperat ures and wi th
heavy eng ine load, there is a ris k of the
eng ine overheating .
- T he front spoiler ensures the correct dis­
tribution of cooling air while driving . If
the spoi ler is damaged, the effect of the
coolant can be reduced and there is a risk
of the engine overheating. See your au­
thorized Audi dealer or qualified repair
facility .

loading the roof rack
Always distribute loads evenly . Make sure
anything on the roof rack is securely tied
down.
,. Always distribute the loads on the roof rack
evenly .
,. Always attach items to the roof rack securely
before you d rive off.
The maximum perm iss ible roof we ight is
165 lb (75 kg ). The roof weight is the total of
the we ight of the roof rack, the attachments
and the cargo you are carry ing. You m ust also
not exceed the maximum load weight for the
roof rack you are using.
When us ing a roof rack system which has a
l owe r load carry ing capac ity, you must not use
up the total max imum pe rm issib le load carry ­
i ng capac ity specified above. Instead, you
should load the roof rack system only to the
maximum capacity specified by the manufac­
turer of the roof rack system.
A WARNING
Weak, damaged or improper straps used
to secure items to the roof rack can fail
during hard braking or in a collision and
cause se rious personal injury .
- Make sure the roof rack is insta lled exact­
ly as specified above¢
page 59.
-Always use suitable mounting straps for
securing items to the roof rack to help
prevent items from shift ing o r fly ing for­
ward.
- Items on the roof rack must always be sec urely mounted.
- The use of a roof rack can negative ly af­
fect the way a vehicle handles . Ca rgo
that is larg e, heavy, bulky, long o r flat
will have a g reater negative influence on
the vehicle's aerodynamics, center of
gravity and overal l handling. Always
dr ive slowly, avo id sudden braking and
maneuvers when transporting cargo on
the roof of your vehicle.
- Never exceed the maxim um permissible
load carrying capacity of the roof of your
veh icle, the permissible axle weights and
the permissible total weight of your vehi­ cle ¢
page 265, Weights.
@ For the sake of the env ironment
As a result of the increased wind resist­
ance created by a roof rack, your vehicle is
us ing fuel unnecessarily . So
remove the
r oof rack after using it .

128 Driving safety
-Place heavy objects as far forward in
the luggage compartment as possible.
- Never exceed the Gross Axle Weight Rat­
ing or the Gross Vehicle Weight Rating
specified on the safety compliance stick­
er on the left door jamb. Exceeding per­
missible weight standards can cause the
vehicle to slide and handle differently .
- Please observe information on safe driv­
ing
~ page 121.
A 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 because 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 power roof",
- Open all air outlets in the instrument
panel,
- Switch off the air recirculation,
- Set the fresh air fan to the highest
speed.
A WARNING
Always make sure that the doors, all win­
dows, the power roof* 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.
- Never leave your vehicle unattended, es­
pecially with the luggage compartment
lid left open. A child could crawl into the
vehicle through the luggage compart­
ment and close the rear lid becoming
trapped and unable to get out. Being
trapped in a vehicle can lead to serious
personal injury.
-
'
- Never let children play in or around the
vehicle.
- Never let passengers ride in the luggage
compartment. Vehicle occupants must
always be properly restrained in one of
the vehicle's seating positions .
(D Tips
-Air circulation helps to reduce window
fogging. Stale air escapes to the outside
through vents in the trim panel. 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 la­
bel is located on the driver's side B-pillar.
The tire pressure label lists the recom­
mended 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 manufactured.
For recommended tire pressures for nor­
mal load conditions, please see chapter
~ page 229.
Tie-downs
The luggage compartment is equipped with
four tie-downs to secure luggage and other
items.
Use the tie-downs to secure your cargo prop­
erly ~
page 12 7, Loading th e luggage com­
par tment.
In a collision, the laws of physics mean that
even smaller items that are loose in the vehi­
cle will become heavy missiles that can cause
serious injury. Items in the vehicle possess en­
ergy which vary with vehicle speed and the
weight of the item . Vehicle speed is the most
significant factor.
For example, in a frontal collision at a speed
of 30 mph (48 km/h), the forces acting on a 10-lb (4 .S kg) object are about 20 times the
normal weight of the item . This means that
the weight of the item would suddenly be about 200 lbs. (90 kg). You can imagine the
injuries that a 200 lbs. (90 kg) item flying ..,_

Smart Technology Notice about data
recorded by vehicle
control modules
Your veh icle is not equipped with an Event Da­
ta Recorde r (EO R), installed by some manu­
facture rs fo r the express purpose o f capturing
data for retr ieval after an accident or cras h
event . EDR's a re sometimes called "crash re ­
corders".
Some state laws res trict the retr ieval or down ­
l oadi ng of data stored by E DR's that were in ­
stalled in a veh icle for the exp ress purpose of
retrieving data after an accide nt or crash
event w ithout the owner's consent.
A lthough yo ur vehicle is no t equ ipped w it h an
EDR, it is equipped with a number of elect ron­
ic control modules fo r various vehicle systems
such as, for examp le, eng ine f unction, em is­
sion control, as well as for the airbags and
safety belt s.
These electronic contro l modules also record
veh icle -re lated data dur ing no rma l veh icle op­
erat ion for d iagnostic and repa ir purposes .
T he recording capacity of the electronic con­
trol modules is limited to data (no sound is re ­
corded) and only a small amount of data is ac­
tually recorded ove r a ve ry limited pe riod of
time and stored when a sys tem faul t or o ther
condition is se nse d by a cont rol u nit. Some o f
the data then stored may re la te to vehicle
speed, dir ect io n, bra king as we ll as restra int

Electronic stabilization
control (ESC)
Description
The ESC reinforces driver safety. It reduces
the r isk of slipp ing and improves driving sta ­
b ili ty . E SC detects cr itical s it u ations such as

Anti-lock braking system (ABS)
ABS prevents the whee ls from locking when
braking . The vehicle ca n still be steered even
dur ing ha rd braking. App ly steady pressure to
the b rake peda l. Do not pump the p edal. A
puls ing in the bra ke peda l indicates t hat the
system is acting to st abil ize the ve hicle.
Brake assist system
The brake ass ist system can decrease braking
dis tance. It increases bra king power when the
drive r presses the bra ke peda l quickly in emer­
gency s ituations. Yo u m ust pres s and hol d the
brake pedal unt il the dangerous s it u at ion is
ove r. In vehicles with adap tive c ruise control *,
the b rake assist system is more sensitive if the
distance detected to the vehicle ahead is too
small.
Anti-slip regulation (ASR )
ASR reduces eng ine power when the drive
whee ls beg in spi nning and adapts the fo rce to
the road conditions . This makes it easier to
start, accelerate and dr ive up inclines.

226 Tire s and wheel s
-Never mount used tires on yo ur vehicle if
you are not sure of their "previous histo­
ry." Old used tires may have been dam­
aged even though the damage cannot be
seen that can lead to sudden t ire failure

Cold tire inflation pressure
Tire pressure affects the overall handling, performance and safety of a vehicle.
Fig. 156 Tir e p ress ure la bel: located on driver 's s ide B·
p ill ar
Tire pressure generally refers to the amount
of air in a tire that it needs it to do its job and
safely carry the combined load of the entire
vehicle and its contents . Tire pressure is
measured in kilopasca ls (kPa), the interna­
tional measuring unit and in pounds pe r
squa re inch (PSI). Tire pressure is based in
part on the vehicles design and Load limit -
the greatest amount of weight that the vehi­
cle can carry safe ly and the t ire size . The prop­
er tire pressure is frequent ly referred to as the
"recommended cold tire inflation pressure."
Air in the tires expands when the tire heats up
because of internal friction when it flexes in
use . The tire pressure is higher when the tire
has warmed up than when it is "cold ."
It is the
in flat ion pressure i n a "cold " tire that counts.
Therefore, you shou ld neve r let air out of a
warm tire to ma tch "cold tire inflation pres­
sure" recommendations. The tir es wo uld then
be underinflated and could fail suddenly .
Maintaining prop er t ire pressure is one of the
most impor tant things you can do to help
avoid sudden tire failure. Underinflated tires
are a ma jor cause of s udden tire failure . Keep·
ing tires at the right pressure is also impor­
tant for safe and responsive vehicle handling,

sures are particularly important when the
vehicle is being driven at higher speeds, and
then especially when heavily loaded even
within the permissible load-carrying capaci­

If you wish to improve comfort when operat­

pants), you can adjust tire pressures to those
specified for normal vehicle load. Before op­
erating the vehicle at maximum load, you
must increase the tire pressures to those

ways compa re the tire size designation on the
tire pressure label on your vehicle wit h the
tires on your vehicle . Make s ure that the tire
size information on the veh icle label is the
same as the s ize of the tires on the vehicle.
This is especially important if the vehicle be ­
longs to someone else or you bought the veh i­
cle with different rims/tires or you boug ht the
ve hicle as a previously owned vehicle.
Remember, your safety and that of your pas­
sengers also depends on mak ing su re that
l oad limits are not exceeded. Vehicle load in­
cludes everybody and everything in and on the
veh icle. These load limits are technically refer­
red to as the vehicle's Gross Vehicle We ight
Rating ("GVWR") . The Gross Ax le Weight Rat ­
ing ("GAWR") is the maximum load that can
be app lied at each of the veh icle's two axles.
The Gross Vehicle Weight Rating and the
Gross Axle Weight Rating are listed on the
safety compliance st icker label located on the
driver's side B-p illa r. The t ire pressure label o n
your Aud i lists the maximum combined
weight of a ll of the occupants and luggage or
other cargo that the vehicle can carry. For the
l ocation of the tire pressure labe l~
fig. 156.
A WARNING
Overloading a vehicle can cause loss of ve­
hicle control, a crash or other accident, se­
rious personal injury, and even death.
- Carrying more weight than yo ur vehicle
was designed to carry will prevent the
vehicle from handling properly and in­ crease the risk of a loss of veh icle con­
trol.
- The brakes on a veh icle that has been
overloaded may not be able to stop the
vehicle within a safe distance .
- Tires on a vehicle that has been overload­
ed can fail suddenly causing loss of con­
t rol and a crash.

-Always make sure that the total load be­
ing transported - includ ing the weight of
a trailer hitch and the tongue we ight of a
loaded trailer -does not make the vehi­

A WARNING
- Inco rrect tire pressures and/or underin­
flation can lead to a ser ious or fatal acci­
dent.
- Inco rrect tire pressures and/or underin­
flation cause increased tire wear and can
affect the handling of the vehicle.
- Inco rrect tire pressures and/or underin­
flation can a lso lead to sudden t ire fail­
ure, including a blowou t and sudden de­
flation, caus ing loss of veh icle contro l.
Checking tire pressure
The correct tire pressure for the tires original­
ly installed on your vehicle is listed on the tire
pressvre label located on driver's side 8-pil ­
lar.
T he recommended tire pressures are on the
ti re pressure label and in the table
~ page 229, Cold tire inflation pressure . This
means that the pressure m ust be checked and
adjusted when the tire has not been dr iven for
more than a couple of miles (kilometers) at
low speeds during the previous three hours.
Air in the tires expands when the tire heats up
as a result of internal frict ion as it flexes in
use. The tire pressure is h igher when the tire
has warmed up t han when it is "cold."
It is the inflation pressure in a "cold" t ire that
counts. Therefore, you should never let a ir out
of a warm tire to match "Cold tire inflat ion
pressure" recommendat io ns ~
page 229 . Th e
ti res wo uld then be unde rinfl ated and co uld
fail suddenly.
T he tire pressure label on your Audi lists the
recommended co ld tire inflation pressures at
max imum capacity for the new, or ig inal
equipment tires that were on your vehi cle at
