Driving Safely ---------------------"~'---
Important things to do before driving
Safety is everybody's job! Vehicle and occupant safety
always depends on the informed and careful driver.
For your safety and the safety of your passengers, before
driving always:
- Make sure that all lights and signals are operating
correctly.
- Make sure that the tire pressure is correct.
- Make sure that all windows are clean and afford good visi-
bility to the outside.
- Secure all luggage and other items carefully::::>
page 93.
-Make sure that nothing can interfere with the pedals.
- Adjust front seat, head restraint and mirrors correctly for your height .
- Instruct passengers to adjust the head restraints according to their height.
- Make sure to use the right child restraint correctly to
protect children ::::,
page 215, "Child Safety".
- Sit properly in your seat and make sure that your passen­ gers do the same::::,
page 73, "General recommenda­
tions".
- Fasten your safety belt and wear it properly. Also instruct
your passengers to fasten their safety belts properly

What impairs driving safety?
Safe driving is directly related to the condition of the
vehicle, the driver as well as the driver's ability to concen­
trate on the road without being distracted .
The driver is responsible for the safety of the vehicle and all
of its occupants. If your ability to drive is impaired, safety
risks for everybody in the vehicle increase and you also
become a hazard to everyone else on the road::::,,& . There­
fore:
Do not let yourself be distracted by passengers or by using
a cellular telephone.
NEVER drive when your driving ability is impaired (by
medications, alcohol, drugs, etc.).
- Observe all traffic laws, rules of the road and speed limits
and plain common sense .
- ALWAYS adjust your speed to road, traffic and 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 pressure or when
you are stressed .
& WARNING
Impaired driving safety increases the risk of serious personal
injury and death whenever a vehicle is being used.•
Vehicle care Do-it-yourself service Technical data

in. WARNING
Improperly stored luggage or other items can fly through the
vehicle causing serious personal injury in the event of hard braking
or an accident. To help reduce the risk of serious personal injury:
• Always put objects, for example, luggage or other heavy items
in the luggage compartment .
• Always secure objects in the luggage compartment using the
tie-down eyelets and suitable straps.
& WARNING
Heavy loads will influence the way your vehicle 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 compart-
ment 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 handle differently.
• Please observe information on safe driving=>
page 170.
in. 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.
& WARNING (continued)
• 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 panoramic tilting sunroof*,
- Open all air outlets in the instrument panel,
- Switch off the air recirculation,
- Set the fresh air fan to the highest speed.
in. WARNING
Always make sure that the doors, all windows, the panoramic
tilting sunroof* 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 especially with the rear lid
left open. A child could crawl into the vehicle through the luggage
compartment 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 .
(I) Tips
• Air circulation helps to re du ce win dow fogging. Stale air escap es
to the outside th rough vents in the trim panel. Be sure to keep t hese
slots free and open.
• Th e tire pressure must correspond to the load . The tire pressure is
shown on the tire pressure label. On USA vehicles, the tire pressure .,_

label is located on the driver's side 8-p illar . On Canada veh icles, the
ti re pressu re lab el is loca ted ei ther on the d river's s ide 8-pillar or
inside the fuel fille r flap . The tire pressure label lists the recom­
mended co ld tire inflatio n pressures fo r the ve hicle at its maximum
capacity weight and the tires that were on yo ur vehicle at the t ime it
was manufactured . For recommended tire pressures for normal loa d
c ondi tions, p lease see chapte r=>

Tie-downs
The luggage compartment is equippe d with four tie­
d o w ns to secu re lu ggage and other i tems.
Use the t ie-downs to sec ure yo ur ca rgo prope rly=> page 177 ,
"Load ing the luggage compartment" .
In a c oll ision, t he laws of physics mean that eve n small er item s tha t
are loose in the vehicle will become heavy missiles that can cause
s er iou s injury. Ite ms i n t he vehi cle p osses s ene rgy w hich vary w it h
vehicle speed and the weight of the item. Vehicle speed is th e most
sig nifi ca nt fa ctor.
For examp le, in a frontal collis ion at a speed of 30 mph (4 8 km/h) ,
the forces acting on a 10- lb (4.5 kg) object are a bout 20 times the
normal weig ht o f th e ite m. Th is mea ns that t he weight of t he ite m
wou ld s uddenly be abo ut 200 lbs. (90 kg) . You can imagine the inju­
r ies tha t a 200 lbs . (9 0 kg) item fly ing freely throug h the pa ssenge r
compartment could cause in a collision like this.
& WARNING
Weak , damaged or improper straps used to secure items to tie­
downs can fail during hard braking or in a collision and cause
serious personal inju ry.
• Always use suitable mounting straps and properly secure items
to the tie-downs in the luggage compartment to help prevent
items from shifting or flying forward as dangerous missiles.
Controls and equip­ ment Safety first Vehicle operation
& WARNING
(co ntinued )
• When the rear seat backrest is folded down, always u se suit­
able mounting straps and properly secure items to the tie-downs
in the luggage compartment to help p revent items from flying
forward as dangerous missiles into the passenger compartment .
• Never attach a child safety seat tether strap to a tie-down. •

The system operates across the entire speed range in combination
w ith the ABS sys tem. If the A nti-L o ck Brak e System (A BS) mal fun c­
tions, the ESP will also shut down.
How the system works
The Anti-Lock Brake System (ABS), Elect ronic D ifferential Lock (EDL)
and the Anti-Slip Regul ation System (AS R) are in teg rated in the e lec ­
tronic stab ilizat ion program . In addition to the data prov ided by
th ese fun ctions, the ESP control unit re quires addi tional meas ure ­
ment data provided by hig h pe rformance senso rs . The ro tat ional
speed of the vehicle about its vertical axis, veh icle acceleration in the
fore-and-a ft and lateral d irect ions, the brake pressure , a nd the
steerin g ang le are all measured .
Th e d irec tion in whi ch the driver w ishes to tra ve l is d ete rm ined wi th
the a id of the steering a ngle and ve hicle speed and is con tinually
c omp ared wi th the a ctu al b ehavior o f the ve hicl e. If t he two do no t
match, for example, when the vehicle starts hydroplani ng on a wet
roa d, E SP w ill automatica lly bra ke the approp riate whee l to correct
the problem.
Th e ve hicle is t hen stab ilized by the fo rces acting on the whee l during
bra king .
If the ve hicl e is oversteering (the vehicle tu rns too s harp ly
and the rear whee ls slide toward the outside of a curve), the brakes
a re mainly a pplied on the whee l tha t is o n the o uts ide of t he curve. In
the case of a vehicle that is
understeering (the vehicle does not turn
shar ply enough and push es out o f a curve), the b rakes are ap plied as
needed on the whee l th at is on the inside of the curve or additionally
on the ot her wheels . An acoustic s ignal indicates w hen ESP bra ke

Corrosion
T he re may be a te ndency fo r d irt to build u p on the bra ke pads and
co rrosion to form on the d iscs if the car is not dr iven reg ularly o r only
for short trips with litt le use of the bra kes .
If the brakes a re not used freq uen tly, or if co rrosion has formed o n
the discs, it is advisable to clean off the pads and discs by braking
fir mly a few times from a mode rat ely h igh spee d~ & .
Faults in the brake system
If yo u sh ou ld noti ce a sudden increase in b rake peda l trave l, then one
of the two brake circu its may have failed~& .
Low brake fluid level
Ma lfunctions can occ ur in t he brake system if the brake fluid level is
t oo low. The bra ke f lu id level is moni tore d elec tron ically.
Brake lin ing wear status
Brake lin ing wear may be checked by v isua l inspect ion of the condi­

& WARNING
• You should perform braking maneuvers for the purpose of
cleaning the brake system only if road conditions permit. Other
road users must not be put at risk - you may cau se an accident!
• Before descending a steep grade, reduce speed and shift trans­
mission into a lower gear or lower driving range. Do not ride the
brakes or hold the pedal down too long or too often . This could
cause the brakes to get hot and diminish braking efficiency.
• Do not "ride the brakes " by resting your foot on the pedal when
you do not intend to brake . This may cause the brakes to overheat ,
premature wear and increased stopping distance.
• Under certain climatic and operating condition s such as
passing through water , driving in heavy rain or after washing the
& WARNING (co ntinued )
vehicle, the effectiveness of the brakes can be reduced . In winter,
ice can ac cumulate on the brake pads, linings, dis cs and drums.
Carefully apply brakes for a test. Brakes will dry and ice coatings
will be cleaned off after a few careful brake appli cations.
• Driving for an extended period of time on salt-covered roads
without u sing your brakes can also affect braking efficiency . Clean
off accumulated salt coating from b rake discs and pads with a few
careful brake applic ations.
• If you damage the front spoiler, or if you install a different
spoiler, be sure the air flow to the front brakes i s not obstructed .
Otherwise the brake system could overheat reducing the effective­
ness of the entire brake system.
• Failure of one brake circuit will impair the braking capability
resulting in an increased stopping di stance. Avoid driving the
vehicle and have it towed to the nearest authorized Audi dealer or
qualified workshop.
