& WARN ING (con tinu ed)
• Never allow anyone - e speciall y small children - to remain in
the vehicle when it is locked . Locked doors make it more d ifficult
for rescuers to acces s the passenger compa rtment in the e vent of
an emergency. Danger to life!
• Never leave children unsupervi sed in the vehicle . Children
could release the parking brake or mo ve the gearshift leve r out of
gear . The vehicle could start to roll away and cause an accident.
• No matter what the season is, the temperature in a park ed
vehicle can reach dangerous levels. •
Applie s to vehicles : w it h h ill h old ass is t
Starting on hills
H ill hold assist makes it easier to s tart on hill s.
T he system is activated whe n the brake peda l is depressed for a few
s econd s.
After releasing the b rake pedal, the bra ke power is held fo r a
brief
moment to prevent the vehicle from rolling back when star ting. At
t his time , you can eas ily begin to move your veh icle .
& WARNING
• If you did not beg in moving immediately after releasing the
brake pedal , under certain circumstances , the vehicle would begin
to roll backward. Depre ss the brake pedal immediately or engage
the hand brake.
• Should the engine st all , depress the brake pedal immed iately
or engage the hand brake.
• In order to prevent the veh icle from rolling back unintention ­
ally when starting in stop-and-go traffi c, keep the brake pedal
depressed for a few seconds before d riving off.
[I] Tips
You can find out if your vehicle is equipped with "H ill hold as sist " at
an authorized Audi dea lersh ip. •

Stopping on an incline
- Always
hold t he vehicle with the footbrake or parking
b rake in order to preve nt "ro llback "=> & . Do not try to
p reve nt t he v ehicle from ro lli ng back by re vving th e e ngine
whi le it is in gea r.
Starting on a hill
- Apply the hand bra ke fi rmly.
- With t he eng ine in gear , gra dually acce lerate a nd release
the hand bra ke.
T he eng ine c an only be started with the selector leve r in P or N
=>
page 107 . At low amb ient temperatures (14 °F /-10 °(), it i s only
possible to start the engine with the selector lever in P.
W hen pa rking on leve l grou nd , it is suff ic ient to p lace the se lector
lever in P. On a steeply sloping road, you shou ld f irst app ly the
par king brake firmly and then p lace t he selecto r leve r in P. T his way,
you do not overload the paw l mechanism and it is easier to move the
selector lever out of P.
& WARNING
• Never leave your vehicle with the engine running while in ge ar.
If you must lea ve your vehicle with the engine running, set the
parking brake and engage the park lo ck .
• When the eng ine i s running and the transmi ssio n is in gear (D ,
Sor R ) or in "tiptronic " mode, it is ess ential that you stop the
v ehicle with the footbrake. When idling , the transmiss ion of
power doe s not stop completely -the vehicle "creeps".
• Do not a ccelerate when you change the selector leve r position
with th e vehicle stationary and the engine runn ing -risk of an acci­
dent!
• Never place the selector lever in the R or N position wh ile the
v ehicle is moving -risk of a n accident!
& WARNING (continued )
• If you have to bring your vehicle to a stop while on an incline ,
keep the foot brake depressed all the way down so that the vehicle
does not start to roll backward. You should never hold the veh icle
using the clutch if you are going to b e stopped on an incline. If you
do , the clutch will start to slip when it o verheats c aused by the
c onstant overload . Thi s is danger ous be cau se if the vehicl e start s
to roll backward , you could cause an accident. If the clutch should
s tart to slip, you will fee l the vehicle "jerk " and the selector lever
d isplay w ill start blinking.
• Befor e driving down a st eep slope, reduc e your speed and shift
i nto a lower gear w ith "tipt ronic ".
• Do not ride the brakes or apply the brake pedal too often or too
long . Constant b raking causes the brakes to overheat and
s ub stantially reduces braking performan ce, in creases braking
d istance or causes complete failure of the b rake system . •

Hill Descent Assist
Hill Descent Assist helps the driver when driving down
inclines.
H ill Descent Assist is activated by pressing the brake while
descending when the se lector lever is in
D /S . The S tronic transmis­
sion a utomat ically s hifts down to a gear s uitable fo r the in cl ine. H ill
Descent Assist attempts to mainta in the cu rrent vehicle speed when
t he br aking oc curs, as far as physical and technical l imi ts allow.
It
may be necessary to adjust the speed using the brakes .
Hi ll Descent Assist switches off w hen the incline levels out or when
the gas pedal is pressed.
On vehicles with cruise control*=>
page 110, Hill Descent Assist is
also activa ted when the speed is set.

speed acco rding to the road and traffic conditions. Do not let the
e xtra safety afforded by th e ABS tempt you into taking extra risk s.
The ABS cannot overcome the laws of physics .
[ i J Tips
• If ABS is not funct ioning properly, a warning light will come on .
See ~
page 16 .
• If a fault occurs in the ABS, the EDL is also not functioning. This is
ind ic at ed by t he A BS w arni ng light. •
Brake assistant
The broke assistant is designed to achieve the optimum
br oking effect.
Th e b rake ass istant he lps to inc rease t he effective brak ing powe r and
thus to ac hieve a shorter stopping distance.
If the driver presses the
bra ke ped al ve ry qu ickly, the b rake assistant au toma tically bo osts the
brak ing force to the max imum level, up to the point where the anti­
lo ck brak e function (ABS) in tervenes to stop the whee ls from l ocking.
You should then keep the brake pedal pressed unti l the vehicle has
bra ke d to t he require d spee d. T he bra ke ass istan t swi tches itse lf off
as soon as you re lease the b rake pedal.
Th e brake assistant will not be operative if there is a ma lfu nctio n in
t he A BS .
& WARNING
Please remember that the accident risk always increases if you
drive too fast , especially in corners or on a slippery road , or if you
follow th e vehicle ahead of you too closely. An increased accident
risk cannot be compensated even by the brake assistant, so always
maintain a safe speed .•
