Vehicle care I I Technical data

-Contact your authorized Audi dealer for assistance if
necessary.
If the engine coolant level is correct, then the radiator fan may be
the cause of the malfunction.
If the generator warning/indicator light should also illuminate
=> page 19 , then the fan belt may be damaged.
& WARNING
• If your vehicle should break down for mechanical or other
reasons, park at a safe distance from moving traffic, turn off the
engine and turn on the hazard warning lights
=> page 75, "Emer­
gency flasher A".
• Never open the hood if you see or hear steam or coolant
escaping from the engine compartment -you risk being scalded.
Wait until you can no longer see or hear steam or coolant
escaping.
• The engine compartment of any vehicle is a dangerous area.
Before you perform any work in the engine compartment, turn of
the engine and allow it to cool. Follow the warning stickers
=> page 212, "Engine compartment".
0 Note
Do not continue driving if the _F_ symbol illuminates. There is a
malfunction in the engine cooling system -you could damage your
engine. •

Engine oil pressure malfunction 'l=;:f.
The red engine oil pressure warning symbol requires
immediate service or repair. Driving with a low-oil-pres­
sure indication is likely to result in serious damage to the
engine.
If the ~ symbol appears in the display and flashes, the oil
pressure is too low. In addition to the symbol, the following
message also appears in the display:
SWITCH OFF ENGINE AND CHECK OIL LEVEL
Immediate actions
- Pull off the road and stop the vehicle.
- Shut the engine down.
- Check the engine oil level with the dipstick=> page 224.
Dipstick reading checks too low
- Top off oil to the proper level
=> page 225.
- Make sure that the oil pressure warning symbol ~
appears no longer in the display before you start driving
again.
Dipstick reading checks OK
- If the ~ symbol starts flashing again even though the
engine oil level checks OK on the dipstick ,
do not start
driving again and do not let the engine run at idle .
Instead, contact your authorized Audi dealer for assis­
tance.

Acoustic parking system
A pplies to veh ic les : wit h 4 -ch anne l a cou stic park ass is t
Rear acoustic park assist
Acoustic park assist gives a warning a bout o bstacles
behind the vehicle.
Description
The rear acoustic park assist (4 -channel acoustic park assist) deter ­
mines the d istance of the vehic le from an obstac le using u ltrasonic
sensors. The sensors are in the rear bumper. The volume and the
pitch of the chimes can be adjusted through the menu display
=> page 27.
The range at which the sensors start to m easure is about :
To the side
Center rear
Acti v atio n
2 feet (0 .60 m)
5 feet (1.60 ml
The pa rking assist is activated when rever se ge ar is engaged . A brief
tone confirms that the system is activated .
Backing up
Distance warning when backing up starts when an obstacle is
detec ted in the range of the park ass ist system . As the distance
decreases, the time interval between the aud ible tones becomes
shorter .
When the distance is less than 1 foot (0.30 m) , the tone becomes
continuous . At this point you should stop backing up.
Please note that low objects a lready signalled by a warning can
disappear from the sys tem's detection range and wil l not continue
t o be signa lled . ..,

Pote nt ial malf un cti ons
If a warning buzzer sounds for a few seconds when the ign ition is
switched on, there is a system malfunction with the acoustic park
assist. If the malfunction persists until the ignition is switched off,
there will be no acoustic warning at the next attempt to activate the system. Have the problem corrected.
There is no confirmation tone when reverse gea r is engaged if there
is a system malfunction .
For the parking assist to operate, the sensors must be kept clean
and free of ice.
& WARNING
• Sen sor s hav e blind spots in w hic h obj ec ts can not b e dete cted.
P ay s pecial attenti on to small childr en and anim als . They cannot

(D Note
Low obstacles a lready signa lled by a warn ing can disappear from
the system's detection range as they are approached and wi ll not
continue to be signalled. Objects such as barrier chains, trailer draw
bars, thin pa inted vertical poles , or fences may not be detected by
the system -risk of damage.
[ i J Tip s
For the parking assist to operate, the sensors must be kept clean

Emergency release for selector lever
If the vehicle's power supply fails, the selector lever can
be released in an emergency.

Fig. 114 Selector lever:
emergency release
from the Park position
The emergency release mechanism is located on the right
front under the selector lever shift gate. The release proce­
dure requires professional dexterity. We recommend that
you seek assistance.
Removing the selector lever boot
- Engage the parking brake. -
Carefully pry the selector lever boot out of the trim using
a small screwdriver @.
- Pull both sides of the boot upward in the direct ion of the
arrows @.
- Fold the boot upward.
Emergency release for selector lever
- Press the release lever toward the center of the vehicle
with the screwdriver ~ fig. 114
© and hold it in this
position.
- Now press the lock button on the selector lever@ and
move the selector lever to the N position.
- Clip the shift boot back into the shift gate.
If the vehicle has to be pushed or towed if the power supply fails
(e.g. battery is discharged), the selector lever must be moved to the
N position using the emergency locking device .
& WARNING
The selector must only be shifted from the P position if the hand­
brake is firmly applied. Otherwise the vehicle would start moving
unexpectedly on a grade when the selector lever is shifted from
the P position · increasing the risk of an accident. •

(ABS control range). In order for ABS to be ab le to operate optima lly
in th is range, you m ust keep the brake pe dal depressed -do not
"pump the brakes" .
Brake ass istant
T he brake power assist unit increases the pressure that you
ge nera te wi th the brake pedal. I t wo rks only whe n the e ngine is
running .
Automatic full braking
This function al lows fu ll braking in spite of high brake pedal forces
(e .g. whe n the b rakes are seve rely s tresse d beca use the veh ic le is
ful ly loaded). The driver notices this function through a reduction of
pedal force a nd i ncrease d pe dal trave l. W hen the brake peda l is
released, fu ll braking assist switches off again automatically .
If there is an ABS fail ure , the brake assistant and automatic fu ll
brak in g ass ist are not ava ilable.
& WARNING
• ABS cannot suspend the la ws of physics . You should keep this
in mind in particular on an icy or wet road . If ABS control of braking
intervenes , you should adjust your speed immediately to road and
traffic condit ions. Do not be tempted by the increased safety
provided to t ake risks -danger of an accident.
• Please keep in mind that the risk of an accident is increased by
dri ving too fast, pa rticularly in bends and on icy or wet roads , and
by driving too close to the vehicle ahead . The increased risk of an
accident cannot be reduced by the brake as sistant - danger of an
accident .
[ i ] Tips
If a ma lfunction occurs in the ABS, this is signa lled by an indicator
lig ht, see
