::r ' engaged, for example when you notice that t he
next traffic light is red . This produces an engine
b raking effect, wh ich he lps to protect the brakes
and tires and reduces the emissions and f uel con­
sumpt ion to zero (fuel shut-off dur ing decelera­
tion) .
Shift efficientl y
Upshifting earlier is an effective way to save fue l.
Staying in a gear too long uses fue l unnecessari­
ly .
Press down on the acce lerator peda l slowly and
avoid "kick -down".
Avoid full acceleration
You sho uld rare ly t rave l at the maxim um vehicle
speed. High speeds cause a d isp roportiona tely
hi gh increase in fuel consump tion, emissions and
traffic noise . Driving more slowly saves f uel.
Reduce idling time
The Start/Stop system* he lps to reduce the id ling
time automatically. In vehicles wi thout the Sta rt/
Stop system*, it is efficient to switch the engine
off when stopped at ra ilroad crossings and long
red lights . Stopping the engine for
30 -40 sec­
onds already saves more fuel than the amount of
extra fuel needed to restart the eng ine.
I t takes a very long time in idle to wa rm the en­
gine up to operating temperature . Wear and
emissions are especially high in the warm -up
phase. Therefore, you should begin driving im­
mediately after starting the engine. Avoid high
RPMs while do ing th is .
Have maintenance perf ormed regularly
By having maintenance performed regu larly on
your ve hicle, you can he lp to reduce fuel con ­
sumpt ion before you even start to drive. The
maintenance condition of your vehicle not only
affects traffic safety and long-term value but a l­
so impacts fuel consumption . A poorly main­
tained engine can lead to fuel consumpt ion that
i s
1 0% hi gher tha n normal.
Driving
Avoid short trips
T he eng ine and exh aust cleaning system mus t
r each their optima l operat ing temperatu re to ef ­
fectively reduce consumption and emissions.
A cold engine uses a d isp roportionately high
amoun t of fue l. The engine re ac h es operat ing
temperat ure and cons umption norma lizes on ly
after approximate ly 2.5 mi les (4 km) .
Check the tire pressure
To save fuel, ma ke sure the t ires are always i n­
flated to t he correct pressure~
page 340. The
fuel consumpt io n can increase by
5% if the pres ­
s u re is on ly
0 .5 bar too low. Due to the increased
rolling resistance, low tire pressures wi ll also
l ead to greater tire wear and will affect driving
behavior.
Do not drive on winter tires year -round, as this
will consume up to
10% more fuel.
Eliminate unnecessary weight
S ince eve ry po und of ext ra weight increases f uel
co nsump tion , a quick inspect io n of the luggage
compartment may be worth it to avoid unneces ­
sary weight .
When not be ing used , a roof rac k sho uld be re­
moved to decrease the w ind resis tance of the ve ­
hicle . This will save you approximately
12% fu el
at speeds from
62 -75 mph (100 -120 km/h) .
Save energy
The eng ine d rives the generator, which generates
electric ity; the fuel consumpt io n also increases
wi th the dema nd for e lec tric ity . T he refore, sw itch
electrical eq uipment off when you no longer
need it . Examples of eq uipment that uses a lot of
energy are air blowers at a high setting, the rear
window defogger and seat heating* .
@ Note
Do not leave engine idling unattended after
starting. If warning lights sho uld come on to
i ndicate improper operation, they would go
unheeded. Extended idling also produces
heat, which could resu lt in overheating or
other damage to the veh icle or other proper ­
ty .

other debris from the radiator gri lle, under­
body, and whee ls. Look especia lly for foreign
obj ects (such as stones) that may be stuck in
the tire tread.
- Clean th e ve hicle body and underbody and in ­
spect the vehicle for possib le damage.
- Clean t he windows, headlights, tail lights and
the license plate if they are dirty.
- Perform a brake test (especia lly after driving
through water) .
A WARNING
-Be especia lly cautious and aware when driv­
ing under d ifficult conditions and when off­
road. Vehicle damage and injuries may occur
when driving at excessively high speeds or
with incorrect dr iv ing ma neuvers .
- Always adjust your speed and driving style
to the roads, terra in, traffic and weather
cond it ions. Dr ive espec ially slowly if there is
low v is ib ility when offroad.
- Please note that the wheels can spin more
and the vehicle can swerve when in off road
mode, especially whe n the road is s lippery
o r has loose su rface material.
- Driv ing stab ility is reduced w hen in off road
mode.

weather conditions.
~ Take frequent breaks on long trips. Do not drive
for more than two hours at a stretch.
~ Do NOT drive when you are tired, under pres­
sure or when you are stressed .
A WARNING
Impaired driv ing safety increases the risk of
ser ious personal inju ry and death whenever a
vehicle is being used .
Correct passenger
seating positions
Proper seating position for the driver
The proper driver seating position is important
for safe, relaxed driving .
Fig. 219 Correc t seating pos ition
F or your own s afety and to reduce the risk of in­
jury in the event of an accident, we recommend
that you adjust the driver 's seat to the following
position:
~ Adjust the dr iver's seat so tha t you can easily
push the pedals all the way to the f loor wh ile
keeping your knee(s) s light ly bent
c::> _& .
~ Adjust the ang le of the seatback so that it is in
an upright position so that your back comes in
full contact w ith it when you drive.
~ Adjust the steering wheel so that there is a dis­
tance of at least 10 inches (25 cm) between the
stee ring wheel and you r breast bone

If no t possib le, see you r autho riz ed Aud i dea le r
abo ut adapt ive eq uipment.
Dri ving safety
~ Adjust the steering wheel so that the steering
wheel and airbag
cover points at your chest and
not at yo ur face.
~ Grasp the top of the steering wheel with your
elbow(s) slightly bent.
~ Adjust the head restra int so the upper edge is
as
even as possible w ith the top of your head . If
that is not possib le, t ry to adjust the head re­
straint so that it is as close to this posit ion as
possible .
~ Fasten and wear safety belts correctly

A WARNING
-
Drivers who are unbelted, out of position or
too close to the airbag can be seriously in­
jured by an airbag as it unfolds. To help re­ d uce the risk of serious personal injury:
- Always ad just the driver's seat and the
steer ing whee l so that there are at least
10 inc hes (25 cm) between you r breastbone
and the steering wheel.
- Always hold the steering wheel on the out­
side of the steering wheel r im with your
hands at the 9 o'clock and 3 o' clock posi­
tions to help reduce the risk of personal in­
ju ry if the driver's airbag inflates.
- Never hold the stee ring wheel at the
12 o' clock position o r with you r hands at
o ther posi tions ins ide the s teer ing whee l
rim or on the steering wheel hub. Holding
the steering wheel the wrong way can cause
serio us injuries to the hands, arms and head
if the dr iver's airbag dep loys.
- Pointing the steering wheel toward your
face decreases the ability of the supplemen­ tal driver's airbag to protect you in a coll i­
sion.
- Always sit in an upright position and never
lean aga inst or place any part of your body
too close to the area where the airbags are located .

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 341 .
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 257, 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 . ..,.

:E ' -For safety reasons in severe accidents, the
alternator and starter are separated from
the vehicle battery with a pyrotechnic circuit
interrupter.
- Work on the pyrotechnic circuit interrupt­
er must only be performed by a qualified
technicians who have the experience, in ­
formation and special tools necessary to
perform the work safely.
- If the vehicle or the circuit interrupter is
scrapped, all applicable safety precautions
must be followed .
@ For the sake of the environment
Undeployed airbag modules and pretension­
ers might be classified as Perchlorate Materi­
al -special handling may apply, see
www.dtsc.ca.gov/hazardouswaste/perchlo­ rate. When the vehicle or parts of the re­
straint system including airbag modules and
safety belts with pretensioners are scrapped,
all applicable laws and regulations must be
observed. Your authorized Audi dealer is fa­
miliar with these requirements and we recom­
mend that you have your dealer perform this
service for you.
Other things that can affect Advanced
Airbag performance
Changing the vehicle's suspension system can
change the way that the Advanced Airbag System
performs in a crash . For example, using tire-rim
combinations not approved by Audi, lowering the
veh icle, chang ing the stiffness of the suspens ion,
including the springs, suspension struts, shock
absorbers etc. can change the forces that are
measured by the airbag sensors and sent to the
electronic contro l unit. Some suspension changes
can, for example, increase the force levels meas­
ured by the sensors and make the airbag system
deploy in crashes in which it would not deploy if
the changes had not been made. Other kinds of changes may reduce the force levels measured by
the sensors and prevent the airbag from deploy­
ing when it should .
Airbag system
A WARNING
Changing the vehicle's suspension including
use of unapproved tire-rim combinations can
change Advanced Airbag performance and in­
crease the risk of serious personal injury in a
crash.
- Never install suspension components that
do not have the same performance charac­
teristics as the components originally instal­
led on your vehicle.
- Never use tire-rim combinations that have
not been approved by Audi.
Side airbags
· Description of side airbags
The airbag system can provide supplemental
protection to properly restrained occupants.
Fig. 237 Side a irbag locatio n in the driver's seat
The side airbags are located in the sides of the
front seat backrests ¢
fig. 23 7 and the rear back­
rest* facing the doors.
The side airbags installed for the front seating
pos itions have been des igned and certified to
help reduce the risk of injury that can be caused
by airbags when they inflate, particularly when
the occupant s itting next to it is not seated prop­
erly. The side airbag for the front passenger seat
can be used w ith proper ly installed chi ld re­
straints . Please be sure to read the important in­
formation and warnings whenever using a child
restraint in a vehicle: Safety belts¢

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.
_&. WARNING -
-Never drive faster than the maximum permitted speed
for your tires. This could cause
the tires to heat up too much.
This increases the risk of an
accident because it can cause
the tire to burst .
-Always adapt your driving to the road and traffic condi-
330
tions . Drive carefully and re­
duce your speed on icy or slip­
pery roads . Even winter tires
can lose traction on black ice.
(@ Note
-Please note that summer and
winter tires are designed for
the conditions that are typical
i n those seasons . Aud i recom­
mends using winter tires dur­
ing the winter months . Low
temperatures significantly de­
crease the elasticity of summ­
er tires, which affects traction
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
t ions. The surface of the r ims
does not have sufficient corro­
sion protection for this and
could be permanently dam ­
aged by road salt or similar
substances.
