78 On the road
& WARNING
-When you leave your vehi cle -even if on­
ly brief ly -always take the ignition key
with yo u. This applies par ticu larly when
children remain in the veh icle. Otherw ise
the ch ildren could start the engine, re­
lease the parking brake or operate elec­
trical equipment (e.g. power windows) .
There is the risk of an accident.
- When the vehicle is locked, no one -par­
t icularly not children should remain in
the vehicle. Loc ked doors make it more
difficult for emergency wor kers to get in­
to the vehicle - putt ing lives at risk.
Starting from rest
The starting assist function ensures that the
parking brake is released automatically upon starting.
Stopping and applying parking brake
" Pull the switch ID to apply the park ing
brake.
St arting and automa tically relea sing the
parking brake
.. When you start to drive as usua l, the park­
ing brake is automatically released and you r
vehicle begins to move.
When stopp ing at a traff ic signa l or stopp ing
in city traffic, the parking brake can be ap­
plied . The veh icle does not have to be held
with the footbrake. The par king brake elimi­
nates the tendency to c reep with a drive range
engaged. As soon as you dr ive
off as usua l,
the park ing brake is released automatically
and the vehicle starts to move.
Starting on slopes
When sta rt ing on in cl ines, the starting ass ist
p revents the veh icle from uninten tionally ro ll­
ing bac k. The braking force o f the parking
brake is not released un til sufficient dr iving
force has been b uilt up at the whee ls.
(D Tips
For safety reasons, the parking bra ke is re­
l eased automatically only when the driv­
er's safety belt is engaged in the buckle.
Starting off with a trailer
To prevent rolling back unintentionally on an
incline, do the following:
.. Keep the sw itch(®) pulled and depress the
accelerator. The pa rking bra ke stays applied
and prevents the vehicle from roll ing back­
ward.
" You can release the switch© once you are
sure that you are developing enough for­
wa rd momentum at the wheels as you de­
press the acce lerator.
Depend ing on the we ight of the rig (vehicle
and trailer) and the severity of the incline, you
may roll backwards as you start. You can p re­
vent rolling backwa rds by holdi ng the par king
brake switch (®) pulled o ut and ac celera ting -
j u st as you wou ld w hen s tarti ng on a hill wi th
a conventiona l hand brake.
Emergency braking
In the event that the conven tional brake sys­
tem fails or locks.
"I n an emergency, pull the switch(®) and
cont inue to pull it to slow your ve hicl e down
w ith the par king b rake.
" As soon as you re lease the swi tch (®) or ac -
celerate, the braking process stops.
If you p ull the swi tc h (®) a nd hold it above a
speed of about 5 mph (8 km/h), the emergen­
cy braking f unction is initiated. The ve hicle is
braked at all four whee ls by activating the hy­
draulic brake system. The brake performance
is similar to making an emergency stop¢&..
In order not to activate the emergency brak-
ing by mistake, an audib le warning tone (buz ­
zer) sounds when the switch(®) is pulled. As ..,.

194 Intelligent technology
vehicles with adaptive cruise control*, the
brake assist system is more sensitive if the
d istance detected to the vehicle ahead is too
smal l.
Anti -slip regulati on (ASR )
ASR reduces engine power when the drive
wheels begin to spin and adapts the force to
the road conditions. This makes it easier to
start, accelerate and drive up hills.
Electronic diffe rential lock (EDL )
The EDL brakes wheels that are spinn ing and
transfers the drive power to the other wheels .
This function is available up to abo ut 75 mph
(120 km/h) .
I n extreme cases , ED L automat ic all y switches
off to help keep the brake on the braked whee l
from overheating . EDL will switch on again au­
tomatically when conditions have returned to normal.
Dynamic st eering*
On vehicles with dynamic steering* , ESC helps
stabilize the steering in critical situations .
Electronic interaxle differential lock */
s elective whe el torque control *
The electronic in teraxle d iffe ren tial lock (fro nt
wheel drive) or the select ive whee l torq ue
control (a ll-wheel drive) operates when driv­
ing throug h curves . The front whee l on the in­
side of the curve or both wheels on the inside
of the curve are braked selectively as needed.
T his minimizes sliding in the front wheels and
allows for more precise driving through
curves . The applicable system may not acti­
vate when d rivi ng in wet or snowy conditions.
_& WARNING
- E SC, ABS, ASR, EDL, dynamic steering*
and the E lec tronic interaxle differentia l lock
*/se lective whee l torque control*
cannot overcome the laws of physics.
This is especially important on slippery
or wet roads .
If the systems beg in acting
to stabilize your veh icle, you should im­
mediately chang e you r speed to match
the road and t raffi c conditions. Do not
let the increased safety provided by
these systems temp t you to take risks.
Doing so will increase the risk of a loss of
veh icle cont ro l, collision and serio us per­
sonal injur ies.
- Always adapt your speed to road, traffic
and weather conditions . The risk of los­
ing control of the vehicle increases when
driving too fast, espec ially through
curves and o n slippery or wet roads, and
when dr iv ing too close to vehicles up
a head . ESC, ABS, the brake ass ist sys­
tem, ED L, ASR, dynam ic steeri ng* and
the Electronic in terax le different ial
loc k*/se lective whee l torque control*
cannot prevent collisions .
- Always accelerate wi th spe cial care on
even, smooth s urfaces such as those that
are wet or covered with ice and snow.
The drive wheels can spin even with
these assistance systems that cannot al ­
ways he lp to reduce the risk of loss of ve­
hicle control.
(D Tips
- ABS and ASR only wo rk correctly when
all four wheels are equipped with identi­
cal tires . D ifferent tire si zes can lead to a
reduction in engine powe r.
- You may hear noises when the systems descr ibed are working.
- If the ind icator light

-If the brake booster is not working, the
brake pedal must be pressed considera­
bly harder to make up for the lack of
booster assistance.
Electromechanical

The electromechanical power assist helps the
driver when steering .
Power steering adapts electronically based on
the vehicle speed.
Indicator lights and messages
• Steering defective! Stop the vehicle
If this indicator light turns on and stays on
and this message appears, the power steering
may have failed.
Do
not continue driving. See your authorized
Audi dealer or other qualified repair facility
for assistance .

driving
If the indicator light turns on and the mes­
sage appears, the steering may be more diffi­
cult to move or more sensitive than usual. The
steering wheel may also be at an angle when
driving straight .
Drive slow ly to your authorized Audi dealer or
qualified workshop to have the malfunction
corrected.

With all-wheel drive, all four wheels are driv­
en.
General information
With all-wheel drive, power is distr ibuted to
all four wheels. This happens automatically
depending on your driving style and the road
cond it ions at the time. See also
Qpage 193.
A center differential distributes the driving
power variably to the front and rear axle.
It
works together with selective wheel torque
control, wh ich activates when driving through
curves ¢

tia l*, power distribution to the rear wheels is
variable and can be adjusted with drive se lect
¢ page 100.
The all-whee l drive concept is des igned for
high engine power. Your vehicle is exception­
ally powerful and has excellent driving charac­
teristics both under normal driving conditions
and on snow and ice. Always read and follow
safety precautions ¢

Winter tires
When dr iv ing in the w inter, your ve hicl e w ith
a ll-whee l drive has an advantage,
even with
regular ti res . In winter road conditions it may
be advisable to mount winter tires (o r all-sea­
son t ires) for improved driveability and brak­
ing: these tires must be mounted on
all four
whe els .
See also c:> page 264, Winter tires.
Tire chains
Where tire cha ins are mandatory on certa in
roads, th is normally a lso applies to vehicles
with a ll-wheel drive
c:> page 265, Snow
chains.
Replacing wheel s/tir es
Vehicles w ith all-wheel drive must a lways
have tires of the same size . Also avoid tires
with d ifferent tread depths. For details see
page
c:> page 257, New tires and replacing
tires and wheels.
Off-Road driv ing?
Your Audi does not have enough ground clear ­
ance to be used as an off-road ve hicle . It is
therefore best to avoid rough tracks and un ­
even terrain as much as possible. Also refer to
c:> page 201.
A WARNING
Always adjust your driving to road and traf­
fic conditions . Do not let the ext ra safety
afforded by all-wheel dr ive tempt you into
taking extra risks.
- Alt hough the all-whee l dr ive is
very ef­
fec tive, a lways remember that b raking
c ap aci ty is limited by tire traction. Yo u
sho uld the re fo re not dr ive at excessive
speeds on icy or slippery road su rfaces.
- O n wet road s urfa ces, be c areful not to
drive too fast because the front wheels
cou ld begin to sli de on top of the water
(aq uaplaning) . If this sho uld occ ur, you
will have no warn ing from a sudden in­
crease in engine speed as with a front­
w heel d rive vehicle. A lways drive at
speeds w hich are suited to the road con­
ditions -risk of c rash.
Energy management
Starting ability is optimized
Energy management controls the distribution
of electrical energy and thus optimizes the
availability of electrical energy for starting the engine.
If a vehicle with a conventiona l energy system
is not driven for a long period of t ime, t he bat­
te ry is discharged by idling current consume rs
(e .g. immobili ze r). In certa in circumstan ces it
ca n res ult in the re be ing insu ffic ien t energy

Intelligent energy management in your vehi­
cl e ha ndles the dist rib ution o f electr ica l ene r­
gy. Start ing abili ty is m arke dly improved and
the life of the battery is extended .
Bas ica lly, energy management consists of
battery diagnosis , idling current manage­
ment
and dynamic energy management .
Battery diagnosis
Battery diagnosis continuously determines
the state of the batte ry. Sensors determine
batte ry voltage, batt ery cu rr e nt and battery
tempe ratu re. This de termines the cur ren t
sta te o f cha rge and t he power o f th e battery.
Idling current management
Idli ng cur rent management reduces energy
consumpt ion while the vehicle is standing .
With the ig nition sw itched off, it controls the
energy supp ly to the variou s ele ctri ca l compo ­
nen ts. Da ta from ba ttery d iagnos is is co nsid­
