wheel AUDI Q7 2011 Owner´s Manual

_________________________________________ I_ n_ t_ e_ ll_,igent technology ,__E~-
If an individual wheel begins to rotate too slowly in relation to vehicle
speed and tends to lock, the ABS automatically reduces brake pres­
sure to prevent that wheel from locking .
Thi s automatic adjustment process wi ll cause a
slight vibration of
the brake pedal and some noises to alert you that vehicle speed must
be adapted to existing road and traffic conditions.
_& WARNING
Although the ABS is very effective, always remember that braking
capability is limited by tire traction. Always adjust your driving
speed according to the road and traffic conditions. Do not let the
extra safety afforded by the ABS tempt you into taking extra risks.
The ABS cannot overcome the laws of physics .
(I) Tips
• If ABS is not funct ioning properly, a warning light will come on .
See ~
page 19.
• If a fault occurs in the ABS, the EDL is also not functioning. This is
ind icat ed by the ABS warning light. •
Brake assistant
The brake assistant is designed to achieve the optimum
braking effect.
The brake assistant helps to increase the effective braking power and
thus to achieve a shorter stopping distance.
If the driver presses the
brake peda l very qu ickly , the brake assistant automatically boosts the
braking force to the maximum level, up to the point where the anti­
lock brake function (ABS) intervenes to stop the whee ls from locking.
You should then keep the brake pedal pressed until the vehicle has
braked to the required speed. The brake assistant switches itself off
as soon as you release the brake pedal.
Controls and equip­ ment Safety first Vehicle operation
Automatic full braking
assist
This function allows full braking in spite of high brake pedal forces
(e .g . when the brakes are severely stressed because the veh icle is fully
loaded). The driver notices this function through a reduction of pedal
force and increased pedal travel. When the brake pedal is released,
full braking assist switches off again automatically.
If there is an ABS failure, the brak e assistant and automatic full
braking assist are not available.
Th e brake assistant will not be operative if there is a ma lfunction in
the ABS .
_& 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 the vehicle ahead of you too closely. Increased risk of an
accident cannot be compensated for even by the brake assistant ,
so always maintain a safe speed.•
Servotronic® -advanced power
steering system
The power steering systems uses the power of the
running engine to allow precise steering with little effort.
The advanced Servotronic ® power steering system senses the road
speed and electronically adjusts power assistance to provide
comfortable and safe steering response exactly matched to the
vehicle speed .
Power steering will not work if the engine is off. As a result , the
steering wheel will be hard to turn .
Th e power steering fluid level is checked during the scheduled main­
tenance services.

Note
If t he re is an elect ro n ic malfunc tion, servotroni c will still funct io n
like a conventional power steering system, provid ing a constant
steer ing suppo rt force tha t is no longer proportiona te to the vehi cle
speed. This is most noticeable when t urning the steer ing wheel at low
speeds (for ex ample when p arki ng), -m ore effo rt will be req uire d
than usua l.
• Be aw are of the d iffe ren t than usual steeri ng respo nse and adjust
your steering force accord ingly.
• Have t he pr oblem chec ked and set r igh t by a n Audi dea ler as soo n
as possib le .
[I) Tips
• When the engine is runni ng, neve r hold t he steering wheel turned
a ll the way to the r ig ht o r to t he left fo r longe r th an 1 5 seco nd s. The
powe r steering pump will over heat the hydraulic fluid if yo u keep
holding t he s teering w heel turne d all the w ay. This is likely to damage
the power steer ing system.
• If the powe r stee ring sys tem s ho uld fail entire ly, or if the engine
is not running (for examp le, while be ing towed), you will still be able
t o steer the vehicle. Howeve r,
considerably more effo rt will be
required to do so.
• If the powe r stee ring sys tem s ho uld have a leak, or is not func ­
tioning properly, contact your author ized Audi dealer immediately.
• Th e power s teeri ng system re quir es a specially fo rm ulated
hydraulic fluid. The power stee ring reservoir is the one located
f ar the st to the rea r on t he left side of the eng ine compa rtment
=> page 302. The correct fluid level in the reservo ir is important for
pr op er f unctio ning o f the power steer ing.•

Winter tires
When d riving in the win ter, your vehicle with A ll Whee l Dr ive has an
advantage, even w ith regula r tir es. In w inter road con ditions i t may
be advisable to mou nt wi nte r ti res (or all-seaso n tires) for improve d
dr iveability and b raking: these tires m ust be mounted on
all four

& WARNING
Always adjust your driving to road and traffic conditions . Do not
let the extra safety afforded by All Wheel Drive tempt you into
taking extra risks.
• Although the All Wheel Drive is very effective, always
remember that braking capacity is limited by tire traction. You
should therefore not drive at excessive speeds on icy or slippery
road surfaces.
• On wet road surfaces, be careful not to drive too fast because
the front wheel s could begin to slide on top of the water (aqua- ...

sudden in crease in e ngine speed as with a front -wheel drive
veh icle. Always drive at speeds which are suited to the road condi ­
tions - risk of crash .•
Energy management
Starting ability is optimized
E nergy ma nagement co ntr ols the distribution of elec­
trical energy and thus optimizes the availa bility of elec ­
trical energy for s tarting the engine.
If a vehicle with a convention al ene rgy sys tem is not driven fo r a lo ng
pe riod of time, the battery is d ischarged by idling cu rr ent consumers
(e.g. immo bilizer) . In ce rtain c ircumstances it can result i n there
being insufficien t energy avai lab le to start the engine .
Inte llige nt ene rgy management in your ve hicl e han dles the dist ribu ­

General information
T he ope ra ti on of the Ele ctro nic Stabilization P rogr am ( ESP ) is
expanded for operation away from paved roads. In s ituations where
slip or a different ia l lock in g f unct io n is requ ired, t he ESP offroa d
mode can be activated~
page 256. Hill descent control is also avail­
able in the ESP offro ad mode, wh ich a utomatically bra kes the vehicle
and thereby keeps speed consta nt when d ifferent whee l speeds are
de te cted when descend ing a hill~
page 257. Your Audi also has
permanent all-wheel drive in add ition.
However , your Audi is not a pure offroad ve hicle.
It was not bui lt for
dr iv ing un der extreme cond it ions, e.g. for t rips that ar e in th e natur e
of an exped it io n.
Drive only on road s and offroad sections which match the design of
your vehicle and your abilities as a driver. Never take risks!
Before driving offroad
• Check the eng ine oi l level, tire pressure, coolant level, and the
fluid level in the w indshiel d wa sher rese rvoir.
• Stow luggage items and other objects in the luggage compart ­
me nt, and sec ure t hem agains t slid ing ar ound.
After driving offroad
• After tr ips offroad, remove a ny tw igs and other foreign objects
from the gr ill, the underbody an d the whee ls. Pay special attention to
fore ign obje cts (sto nes) wh ich have be come lodge d in the tire tr ead.
• Clean the body and the vehicle unde rside, and ins pect t he vehicle
for possib le dam age. •
Clean dirty w indows, headlamp lenses, rear lights, and lic ense
plates.
• Perform a bra ke check (pa rticul arly afte r travell ing t hrough
wate r).
& WARNING
• Drive especially attentively and plan ahead in difficult road
condit ions and when offroad. E xcessive speed or incorrect maneu­
vers can cau se injurie s and damage to the vehicle .
• Always adapt your speed and driving style to road, offroad,
traffic, and weather condition s. Drive especially slowl y offroad
when your view is restricted.
• Please be aware that in ESP offroad mode, particularly on a
smooth and slippery road, the wheels may have an increased
tendency to spin and the vehicle may break away - danger of skid­ ding!
• Stability i s limited in the ESP offroad mode.
Avoid dama ge to t he e nvir onment and respect nature .

Driving off road
- Use the hill descent control~ page 257 when dr iving
down steep sections on hills .
Unpaved roads and offroad
Drive slowly on unfamiliar roads and unknown offroad sections, and
loo k ou t for unexpec ted obsta cles (e.g. potho les, rocks, t ree st umps,
etc.).
T o prevent the vehicle from bottoming and avoid damage to the
unde rbody, you should d rive st raight ac ross severe b umps in the
ground with on ly one s ide of the vehicle so that on ly two of your
w heels cross the bumps.
Drive brisk ly throug h sandy or marshy offroad sections and do not
stop, if at all possible.
Driv ing th rough water
N ote the following to avoid vehicle dam age when driving throug h
water, for example on flooded roads:
• T he wate r must not be any higher than the bottom of the ve hicle
body .
• Do not drive faste r th an wal king speed .
Driving on a slope
If yo u ever find you rsel f not able to climb a slope, do not t ry to turn
around, drive back down in
re verse . Otherw ise, you run t he risk of
t ipping over .
If the vehicle threatens to t ip over when driving across a slope, you
must immediately steer downhill in the direction of the slope.
Do not park yo ur vehicle o n steep s lopes o r gr ad es.
To red uce the risk of tipp ing over, drive on s lopes in the di rect io n of
t he downward slo pe (fa ll line) -
not crosswi se .
Driv ing on snow-covered ground
T he s tandard tires fi tted to yo ur vehi cle are not snow t ires. So yo u
should mount wheels with snow t ires in good t ime where winter road
conditions p revail. Befo re dr iv ing on unp lowed stretches o f deep snow, install tire chains
. For tech nica l reasons, t ire chains may only
be ins talle d on the re a r wheels -never on the front whee ls.
& WARNING
After driving through water , mud, slush, etc. , the brakes may be
slow to take effect because of wet brake rotors and pads.
Dry the
brake s first by braking carefully to re store the full braking effe ct.
0 Note
Vehicle components such as the engine, trans mission, s uspension or
electrical system can be severely damaged by dr iv ing through water.
(I) Tips
• Check the dept h of the water before dr iv in g through it.
• Do not stop the vehicle, dr ive in reverse or sw itch the e ngine off
when driving through water.
• K eep in m ind th at on coming vehicles m ay cre ate w aves t hat ra ise
the water level and make it too deep for your vehicle to drive through
safe ly.
• Avoid dr iving through sa lt water because it ca n cause corrosion .•

Trailer towing
"---------------------------------------------------
in. WARNING
Anyone not properly restrained in a moving vehicle is at a much
greater risk in an a ccident . Never let an yone ride in y our car who i s
not prop erly wearing the re straints provided by Audi. •
Trailer towing tips
Important to know
Your vehicle handles differe ntly when tow ing a tra iler because of the
additiona l weight and different we ight distribution. Safety, perfor­
man ce and economy w ill greatly depend on how ca refu lly yo u load
your trailer and operate your rig.
Be fore you actua lly tow your tra ile r, prac tice turning, stopp ing and
back ing u p in a n area away from traffic. Keep pract ic in g until you have
become completely familiar with the way your vehicle -trailer combi­
nation behaves and responds .
Backing up is diff icult and requ ires pract ice. Backing up w ith a trailer
gene rally requires s teer ing a ction opposi te to th at when ba cki ng up
your vehicle witho ut a trailer.
Maintain a greate r d istance between your ve hicl e and the one in front
of yo u. You will need more room to stop . T o compensate fo r the
trai ler, you will need a larger than normal turning radius .
W hen p assing, remember that you c annot acceler ate as fast as yo u
normally wou ld because of the added load. Make sure yo u have
enoug h room to pass. After passi ng, allow plen ty of room fo r yo ur
tra iler before changing lanes again .
Avoid jerky starts, sharp turns or rapid lane changes .
[ i ] Tips
• Do not tow a trai ler d uring the brea k-in perio d of your vehicle. •
If you tow a tra iler, your Aud i may require more frequent mai nte­
n an ce due to the ex tra load:::::>

Parking on a slope
Do not park on a slope with a trailer. If it cannot be
av oided, do so only after doing the following:
When parking:
- Apply the foot brak e.
- Have someone p lac e chocks un der bo th the vehicle and t he
traile r w he els .
- With c hoc ks i n place, slowly release the brakes u ntil the
