& WARNING
• Failure to heed warning light s and other important vehicle
information may result
in serious personal injury or vehicle
damage.
• Whenever stalled or stopped for repair, move the vehicle a safe
d istance off the road, stop the engine, and turn on the emergency
fla sher ~
page 59.
• The engine compartment of any motor vehicle i s a potentially
hazardous area. Before you check anything in the engine compart­
ment , stop the engine and let it cool down. Always exercise
extreme caution when working under the engine hood

Instruments and warning /indicator lights
Electronic Stabilization Program (ESP}
r /
The warning/indicator light monitors the electronic
stabili zation program.
The warning/ind icator light ,., has the following functions:
• it flashes wh ile you are drivi ng, when the ESP or the ASR (Ant i-Slip
Regulation) is working .
• it ill um ina tes when yo u sw itc h on the ignition for app rox imately 2
seconds as a funct ion check .
• it illum inates w hen there is a malfunction in the ESP .
• it illum inates after the battery has been disconnected.
• it illum inates continuously when the ESP is switched off.
• it illumi nates if the re is a malfunct ion in t he ABS, s ince the ESP is
part of the ABS system.
If the ESP warning/ind icator light ill umina tes and stays on after you
have started the engine, this may mean that the co ntro l system has
tempo rari ly switched off the ESP. If this is case , you can reactivate
the ES P by sw itch ing t he ig nit ion off and the n on agai n. The
warning/indicator light should go out to show that the system is fu lly
fu nctional again .
The ESP warn ing/ind icator light will illuminate when the ignition is
switched on if th e ve hicle bat tery has been disconnected and the n
reconnected aga in . The light should go ou t after dr iv ing a short
dis tance if the steer ing whee l is turned s lig htly.

turned on and w ill tu rn off after the eng ine has star ted and has sett
led at constant idle speed . This i nd icates that the MIL is work ing

application
• If the brake warn ing/indicator light does not go out after a few
se cond s and the parking brake rel eased, or light s up while you are
driving , the fluid level in the brake fluid reservoir is too low. If you
believe that it i s safe to do so, proceed immediately at low speed
to the nearest authorized Audi dealer or qualified workshop and
have the brake system in spe cted.
• Please be very careful and always keep
in mind that after
s everal brake application s, you will need greater pressure on the
brake pedal to stop your vehicle. Consequently, you must allow
for increased braking distances. Trying to brake a s quickly a s usual
could lead to an accident. •

& WARNING (conti nu ed )
• Never tran sport object s larger than those fitting completely
into the luggage are a because the rear lid cannot be fully clos ed.
• If you absolutely must dri ve with the rear lid open , observe the
following note s to reduce the risk of po isoning:
- Clo se 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 h ighest speed.
& WARNING
Always make sure that the doors , all windows, the power roof*
and the read lid are securely closed and lo cked to redu ce the ri sk
of inju ry when the vehicle is not being used.
• After closing the r ear 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 . Vehicl e
occupants must alway s be properly restrained in one of the
vehicle 's seating positions.
00 Tips
• The tire pressu re mus t cor respond to the load - see the tire pres­
sure st icker on th e fuel filler doo r. •
The tire pressure must correspo nd to the load . The tire p ressure is
shown on t he tire press ure label. O n USA ve hicl es, t he tire press ure
label is located on the d river's s ide B-pillar. On Canada vehicles, the
tire press ure label is located either on the driver 's side B -pillar or
inside the fuel fille r flap . The t ire pressure labe l lists the recom­
mended co ld ti re inflation pressures for t he ve hicle at its maximum
c apacity weight and the tires that were on yo ur vehicle at the ti me it
was manufactured. For recommended tire pressures for normal load
c ondi tions, p le ase see cha pte r=>

Tie-downs
The lugg ag e co mportment is equipped with four tie­
downs to secure lugga ge and other items.
Use the t ie-downs to sec ure your ca rgo prope rly=> page 131,
"Loading the luggage compartment" .
In a co lli sion, t he laws of phys ics mean tha t even sma ller i tems th at
are loose in the vehicle will become heavy m issi les t hat can cause
ser ious injury. Items in the vehicle pos sess energy whi ch v ary wi th
vehicle speed and t he weight of the item. Vehicle speed is the most
significant factor .
For exampl e, in a fron tal col lis io n at a speed of 30 mp h (4 8 k m/h),
the forces actin g on a 10 -lb (4.S kg) o bject are about 20 times t he
normal weight o f the item. This means that the weig ht of the item
wou ld suddenly be abo ut 200 lbs. (90 kg) . You can imagine the inju­
r ies tha t a 200 lbs. (90 kg) i tem flying freely thro ugh t he p assenge r
compartment could cause in a collision like this.
& WARNING
Weak , damaged or improper straps used to secure items to t ie­
downs can fail during hard braking or in a collision and cause
ser ious personal injury.

-Safety belts pn, _______________ _
-Make sure that your passengers also buckle up a nd prop ­
erly wear their safety belts .
- Protect c hildren with a child rest raint system appropria te
fo r the size and ag e.
The warn ing light ~ in the instrument cluster lights up when the igni­
tion is sw itched on as a reminder to fasten the safety belts. In addi­
tion, you w ill hear a wa rning tone for a certa in period of t im e.
Fasten your safety belt and ma ke sure that your passenge rs also
properly put on their safety belt s.
& WARNING
• Safety belts are the singl e most effective means available to
reduce the risk of serious injury and death in automobile a cci­
dents . For your protection and that of your pas senger s, always
co rrectly wear safety belts when the vehicle is mo ving .
• Failure to pay attention to the warning light that come on,
could lead to personal injur y.

T he p hys ica l pr inc iples are simple. Both the vehicle and the passen­
gers possess energy which var ies wit h veh icle speed and body weight.
Enginee rs ca ll t his ene rgy "kinetic energy."
The higher the speed of the veh icle and the greater the vehicle's
we ight, the more energy that has to be "absorbed" in the crash .
Vehicle speed is the most sig nifican t fa ctor. If t he speed doubles
from 15 to 30 mph (25 to 50 km/h), the energy increases 4 times! .,
