Driving safety
A 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 th e driv­
er's side B-pillar. Exceeding permissible
weight standards can cause the vehicle to
slide and handle differently .
- Please observe information on safe driving
<=) page 252.
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 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 sunroof*,
-Open all air outlets in the instrument pan-
el,
- 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 sunroof* and the rear lid are se­
curely 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.
258
-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.
@ Note
If you are transporting large items with the
backrest folded down*, you should remove
the Rear Seat Entertainment (RSE)* and its
holder* to avoid damage.
© Tips
-Air circulation helps to reduce window fog­
ging. 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 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 recommend­ ed tire pressures for normal load condi­
tions, please see chapter
Q page 336 .
Tie-downs
The luggage compartmen t is equipped with four
t ie-downs to secure luggage and o ther i tems.
Use the tie-downs to secure your cargo properly
Qpage 25 7, L oading the luggage compartment.
In a collision , the laws of physics mean that even
smaller items that are loose in the vehicle will
become heavy missiles that can cause serious in­
jury. Items in the vehicle possess ene rgy which
vary with vehicle speed and the weight of the
item . Vehicle speed is the mos t significant fac tor .

Wheels
not permitted can lead to ve­
hicle damage or accidents.
-If you install wheel covers on
the vehicle, make sure they al­
low enough air circulation to
cool the brake system. If they
do not, this could increase the risk of an accident.
Tire wear/damage
Fig. 267 Tire profile: treadwear indica­
tor
Tire wear
Check the tires regularly for wear.
-Inflation pressure that is too low
or high can increase tire wear
considerably.
-Driving quickly through curves ,
rapid acceleration and heavy
braking increase tire wear.
-Have an authorized Audi dealer
or authorized Audi Service Facili-
l) Obey any applicable regulations in your
country.
334
ty check the wheel alignment if
there is unusual wear.
-Have the wheels rebalanced if an imbalance is causing noticeable
vibration in the steering wheel.
If you do not, the tires and other
vehicle components could wear more quickly .
Treadwear indicator
Original equipment tires contain
treadwear indicators in the tread pattern, which are bars that are 1/16 in (1.6 mm) high and are
spaced evenly around the tire per­ pendicular to the running direc­
tion
¢ fig. 267. The letters "TWI"
or tr iangles on the tire sidewall
indicate the location of the tread­
wear indicators.
The t ires have reached the mini ­
mum tread depth

have worn down to the treadwear
indicators. Replace the tires with
new ones

Determining correct load
limit
Use the example below to calcu­
late the total weight of the pas ­
sengers and luggage or other
things that you plan to transport
so that you can make sure that
your vehic le w ill not be over load­
ed .
Steps for Determining Correct
Load Limit
1. L ocate the statement "TH E
COMBINED WEIGH T OF OCCU­
PANTS AND CARGO SHOULD
NEVER EXCEED XXX KG OR XXX
L BS" on your vehicle's placard
(tire inflation pressure label)
¢ page 335, fig . 269 .
2. Determine the combined
weight of the driver and pas ­
sengers that w ill be riding in
your vehic le .
3. Subt ract the combined weight
of the driver and passengers
from "XXX" kilograms or "XXX"
Wheels
pounds shown on the stick­
er ¢ page 335, fig. 269 .
4. The resulting figure equals the
available amount of cargo and
luggage load capacity . For ex­
ample , if the
"XXX" amount
equa ls
1400 lbs . and there will
be five
150 l bs . passengers in
your vehicle, the amount of
available cargo and luggage
load capacity is
650 lbs .
(1 400- 750 (5 X 1 50) = 650
lbs .)
5. Determine the comb ined
weight of luggage and cargo
being loaded on the vehicle .
T hat weight may not safely ex­
ceed the availab le cargo and
luggage load capacity calculat­
ed in Step 4 .
6 . If your vehicle will be towing a
tra iler, load from your tra iler
w ill be transferred to your ve ­
hicle. Consult this manual to
determine how this reduces
the availab le cargo and lug­
gage load capacity of your veh i­
c le .
.,. Check the tire sidewall
(¢ page 326, fig . 266) to deter ­
mine the designated load rat ing
for a specific t ire .

Wheels
The grade C corresponds to a leve l of perform ­
ance which all passenger car tires must meet un­
der the Federa l Motor Vehicle Safety Standard
No.
109. Grades Band A represent higher levels
of performance on the laboratory test wheel than
the minimum required by law.
A WARNING -
The traction grade ass igned to this tire is
based on straight-ahead braking traction
tests, and does not include acce le rat ion, cor­
ne ring, hydroplaning or peak traction charac­
teristics.
A WARNING
Th e temperatu re grade for this tire is estab­
lished for a tire that is properly inflated and
not overloaded. Excessive speed, underinfla­
tion, or excessive loading, either separate ly or
in combination, can cause heat buildup and
possible tire failure.
A WARNING
-
-
Temperature grades apply to tires that are properly inflated and not over or underinflat­
ed.
Tire pressure monitoring system
(l) General notes
Each t ire, including the spare (if provided),
should be checked monthly when cold and inflat­
ed to the inflation pressure recommended by the
ve hicl e manufacturer on the vehicle placard or
tire in flatio n press ure label. ( If yo ur vehicle has
t ires of a different siz e than the size indicated on
the vehicle placard or tire inflation pressure la­
be l, you should determine the proper tire infla­
tion pressure for those t ires) .
As an added safety feature, your veh icle has been
equipped with a tire pressure monitoring system
(TPMS) that illuminates a low tire pressure te ll­
tale when one or more of your t ires is significant­
ly under-inflated. Accordingly, when the low tire
pressure tellta le illuminates, you should stop and
342
check your tires as soon as possible, and inflate
them to the proper pressure . Driving on a signifi ­
cant ly under-inflated t ire causes the t ire to over­
heat and can lead to tire fa ilure . Under-inflation
also reduces fue l eff iciency and tire tread life,
and may affect the vehicle's handling and stop ­
ping ability .
Please note that the TPMS is not a substitute for
proper tire maintenance, and it is the dr iver's re­
spons ibility to maintain correct tire pressure,
even if under-inflation has not reached the level
to trigger illumination of the TPMS low tire pres­
su re te lltale .
Your vehicle has also been equipped with a TPMS
malfunction indicator to indicate when the sys­
tem is not operating prope rly . The TPMS mal­
function indicat or is combined with the low tire
pressure telltale. When the system detects a
malfunction, the telltale will flash for approxi ­
mately one minute and then remain continuously
illuminated. This sequence wi ll continue upon
s ub sequent vehicle start-ups as long as the mal­
funct ion exists.
When the malfunction indicator is illuminated,
the system may not be able to detect or signal
l ow tire pressure as intended. TPMS malfunctions
may occur for a variety of reasons, including the
i nstallation of replacement or alternate tires or
wheels on the veh icle that prevent the TPMS
from functioning properly. Always check the
TPMS ma lfunction telltale after replac ing one or
more tires or wheels on you r vehicle to ens ure
that the rep lacement or alternate tires and
whee ls allow the TPMS to continue to function
properly.
