2014 AUDI Q7 brakes

Driving off road
Driving in difficult road
conditions and offroad
General information
The operation of the E lectronic Stabilization
Control (ESC) is expanded fo r operation away
from paved roads. In situations where slip or a
differential lock ing funct ion is required, the
offroad mode can be activated
c:::> page 224.
Hill descent control is a lso ava ilable in the off ­
road mode, which automat ically brakes the
ve hicl e and thereby keeps speed consta nt
when differe nt w heel speeds a re detected
when descending a hill
c:::> page 226. Your A ud i
a lso has permanent a ll-wheel drive in addi­
tion.
H oweve r, your Aud i is not a pure off road ve hi­
cle . It was not built for d riving unde r extreme
conditions, e.g. for trips that are in the nat ure
of an expedition .
Drive only on road s and offro ad sections
which match the de sign of y our vehicl e and
you r abilitie s as a dri ver. Ne ver t ake ri sks!
Before driving offroad
- Check the eng ine oi l level, t ire pressu re ,
coolant level , and the fluid level in the w ind­
shield washe r reservo ir.
- Stow luggage items a nd other objects in the
l uggage compartment, and sec ure t hem
against s lid ing aro und .
After driving offroad
- After trips off road, remove any twigs and
othe r foreign objects from the grill , the un­
derbody and the wheels. Pay spec ia l atten­
t ion to fore ign ob jects (stones) which have
become lodged in t he tire tre ad.
- Clean t he body and the vehicle unders ide,
and inspect the veh icle for possible damage.
- Clean dirty w indows , headlamp lenses, rear
li gh ts, and license plates .
- Perfo rm a brake check (particularly after
t ravell ing throug h water) .

- Always adapt your speed and driving
style to road, offroad, t raff ic, and weath­
e r condition s. D rive e spe cially slowly off­
road when yo ur view is restricted.
- Please be aware that in offroad mode,
pa rti cularly on a smoo th and s lippery
road, the whee ls may have an increased
tendency to spin and the vehicle may
break away -danger of skidding!
- Stability is limited in the offroad mode .

If the vehicle threaten s to tip o ver when
d riv ing across a slope , you mu st imm ediate­
ly steer downhill in the di rection of the
slope.
D o not park your vehicle on steep slopes or
grades .
To reduce the risk of t ipping over, dr ive on
slopes in the d irection o f the downward slope
(fa ll line) -
not cro sswi se.
~ WARNING
After driving through water, m ud, slush,
etc., the brakes may be slow to take effect
because of wet brake rotors and pads. Dry
the brakes first by braking carefully to re­
store the full braking effect.
(D Note
-
Vehicle components such as the engine,
transmiss ion, suspension or electrical sys­
tem can be severely damaged by driving
through water.
{l) Tips
- Check the depth of the wate r before dr iv­
i ng through it.
- Do not stop the veh icle, dr ive in reverse
or switc h the engine off when driving
t h rough water.
- Keep in mind that oncoming vehicles may create waves that raise the water
leve l and make it too deep for your vehi­
cle to drive through safely.
- Avoid dr iving through sa lt water because
i t can cause corrosion.

240 Trailer towing
Trailer towing
Driving with a trailer
General information
Your Audi was designed primarily for passen­
ger transportation .
If you plan to tow a trailer, p lease remember
that the additional load will affect durability,
economy and performance .
Trailer towing not on ly places more stress on
the vehicle, it also calls for more concentra­
tion from the driver.
For this reason, always fo llow the operating
and driving instructions provided and use
common sense.
@ Note
If you are going to tow a trai ler, you must
activate the trailer operation mode
c:::> page 159, Towing a trailer.
Technical requirements
Trailer hitch
Use a weight-carrying hitch conforming to the
gross trailer weight. The hitch must be suita­ ble for your vehicle and trailer and must be
mounted securely on the veh icle's chassis at a
technically sound location . Use only a trailer
hitch with a removable ball mount. Always
check with the trailer hitch manufacturer to
make sure that you are using the cor rect
hitch.
Do not use a bumper hitch.
The hitch must be installed in such a way that
it does not interfere with the impact-absorb­
ing bumper system. No modifications should
be made to the vehicle exhaust and brake sys­
tems. From time to time, check that all hitch
mounting bolts remain securely fastened.
When you are not towing a trailer, remove the
trai ler hitch ball mount. This prevents the
hitch from causing damage should your vehi­
cle be struck from behind
c:::> A.
Trailer brakes
If your trailer is equipped with a brakin g sys­
tem, check to be sure that it conforms to all
regulations.
T he trailer hydraulic brake system must not be
directly connected to the vehicle's hydraulic
brake system
c:::> A .
Safety chains
Always use safety chains between your veh icle
and the tra iler.
Trailer lights
Trailer lights must meet all regulations. Be
sure to check with your authorized Audi dealer
for correct wiring, sw itches, and relays.
Mirrors
If you are unable to see the traffic behind you
using the regular outside mirrors, then you
must install extended mirrors.
It is important
that you always have clear v is ion to the rear .
A WARNING ,-
- If a trailer has electrical brakes please
note that these brakes are not activated
by the factory-fitted control unit -risk of
accident!
- Afte r removing the trailer hitch, do not
store it in yo ur vehicle. In case of sudden
braking, the hitch could fly forward and
injure you or your passengers.
- Never install a "weight distributing" or
"load equalizing" trailer hitch on your ve­
hicle. The vehicle was not designed for
these kinds of trailer hitches. The hitch
attachment can fail, causing the trailer
to tear loose from the vehicle.
- The Gross Vehicle Weight Rating for your
veh icle, found on the safety compliance
label on the driver's side B-pillar, must
never be exceeded under any c ircumstan­
ces. Exceeding the Gross Vehicle Weight
Rating of your vehicle is likely to damage
your vehicle, and such damage will not
be covered by your Limited New Vehicle
-
Warranty. Exceeding the Gross Vehicle ~

chains, make sure they wi ll not drag on the
road when you are driving .
The cha ins shou ld cross under the tra ile r
tongue to prevent it from dropping in case of
separation from the hitch.
0 Note
If you are going to tow a tra ile r, you must
activa te the trailer operation mode
~ page 159, Towing a trailer.
Driving instructions
Driving with a trailer always requires extra
cor e and consid eration.
To obta in the best poss ible handling of vehicle
and tra ile r, p le ase no te the following:
.. Do not tow a loaded tra iler when your car it­
self is not loaded.
.,. Be especia lly careful when pass ing othe r
vehicles .
.. Observe speed limits.
.. Do not driv e at the maximum p ermissible
speed.
.. Always apply brakes early.
.. Monitor the temperature gauge.
Weight di stributio n
Towing a loaded trai ler with an empty ca r re­
sults in a high ly unstable distribution of
weight . If this cannot be avoided, drive at very
l ow speeds only to avoid the risk of los ing
steering control.
A "balanced" rig is eas ier to operate and con ­
trol. This means that the tow vehicle should
be loaded to the extent possible and permiss i­
ble, while keeping the trailer as light as possi­
b le under the circumstances. Whenever possi­
b le, transfer some cargo to the luggage com­
pa rtment of the tow veh icle wh ile observing
tongue load requirements and vehicle loading
considerations .
Speed
The higher the speed, the more difficult it be­
comes for the driver to control the rig . Do not
drive at the maximum permiss ible speed . Re- duce your speed even more i
f load, weather or
wind conditions are unfavorable - particularly
when going downhill.
Red uce veh icle speed
immediately if the trail­
er shows the slightest s ign of sway ing.
Do not
t ry to stop the swa ying by acceleratin g.
Observe speed limits. In some a reas, speeds
f or vehicles tow ing tra ile rs are lower than for
r egular vehicles.
Always apply brakes early. When driving down hill, shift into a lowe r gear to use the en­
gine braking effect to s low the vehicle . U se o f
the brakes alone can cause them to overheat
and fail.
Coolant temperature
T he coo lant tempe ratu re gauge ~ page 10
must be observed caref ully. If the need le
moves close to the upper end of the scale, re­
duce speed immediately and/or turn off the
air conditioner.
If the coolant temperature warn ing light in
the instr ume nt cluster starts flashing., pull
off the road , stop and let the engine
idle for
about two min utes to prevent heat build -up .
A WARNING "--
Anyone not proper ly restrained in a mov-
ing vehicle is at a much greater risk in an
accident. Never let anyone ride in your car
who is not properly wearing the restraints
p rov ided by A udi .
Trailer towing tips
Important to know
Your vehicle handles d ifferently when towing
-
a trai ler because of the additional weight and
different weight distr ibut ion. Safety, perform­
ance and economy will great ly depend on how
ca refully you load your tra iler and operate
yo ur rig .
Before you act ua lly tow your tra iler, practice
turning, stopping and backing up in an area
away from traffic. Keep pract ic ing unt il you

have become completely familiar with the way
your vehicle-trailer combination behaves and responds.
Backing up is difficu lt and requires practice.
Backing up with a trai ler genera lly requires
steering action opposite to that when backing up your vehicle without a trailer .
Maintain a greater distance between your ve­
hicle and the one in front of you. You will need
more room to stop . To compensate for the
trai ler, you will need a larger than norma l
turning radius.
When passing, remember that you cannot ac ­
celerate as fast as you normally would be ­
cause of the added load . Make sure you have
enough room to pass. After passing, allow plenty of room for your tra iler before chang­
ing lanes again .
Avoid jerky starts, sharp turns or rapid lane
changes.
@ Tips
- Do not tow a traile r during the break-in
period of your vehicle.
- If you tow a trailer, your A udi may re­
quire more frequent maintenance due to
the extra load
<=> page 316.
Parking on a slope
Do not park on a slope with a trailer. If it can­
not be avoided, do so only after doing the fol­
lowing:
When parking:
.. Apply the foot brake .
.. Have someone place chocks under both the
vehicle and the trai ler wheels .
.. With chocks in place, slowly re lease the
brakes until the wheel chocks absorb the
load .
.. Turn the wheels towards the curb .
.. Apply the parking brake .
.. Move the selector lever to P.
When restarting after parking:
.. Apply the foot brake.
Trailer towing 243
.. Start the engine.
.. Move the selector lever to D.
.. Release the parking brake and s low ly pull
out and away from the wheel chocks.
.. Stop and have someone retr ieve the wheel
chocks.
(D Tips
If you move the selector lever of the auto­
matic transmission to P before applying
the parking brake and before blocking the
whee ls, you may have to use more force
l ater to move the lever out of the
P posi­
tion.

A WARNING
-Only wash the vehicle when the ignition
is off and follow the instructions from
the car wash operator to reduce the risk of accidents .
- To reduce the r isk of cuts, protect your­
self from sharp metal components when
wash ing the underbody or the inside of
t he wheel housings.
- After washing the vehicle, the braking ef­
fec t may be delayed due to mo isture on
the brake rotors or ice in the winter. The
brakes must be dried first with a few
careful brake applications.
Q) Note
- If you wash t he vehicle in an automatic
car wash, yo u must fold the exterior m ir­
rors in to reduce the r is k of damage to
the mirrors. Power folding exterior mir ­
rors* must only be folded in and out us­
ing the power folding function.
- Compare the track of your vehicle with
the distance between the guide rails of
the facility -there is a risk of damage to
the wheels and tires .
- Compare the height and width of your
vehicle with the he ight and width of the
tunnel at the fac ility. -
To prevent paint damage, do not wash
the vehicle in direct sunlight.
- T o reduce the r isk o f damage to the sur­
face, do not use insect removing spong­
es, kitchen sponges or similar items.
- Matte finish painted vehicle compo­ nents:
- To reduce the risk of damage to the
surface, do not use polishing agents or
ha rd wax .
- Never use car wash cycles that apply protective wax.
It can destroy the
matte fin ish effect .
- Do not place any stickers or magnet ic
signs on vehicle parts painted w ith
matte fin ish paint. The paint cou ld be
damaged when the stickers o r magnets
a re removed.
@ For the sake of the environment
Only wash the ve hicl e in facilities spec ially
designed for that purpose . This will red uce
the r is k of dirty water contam inated with
oil from entering the sewer system.

268 Check ing and filling
If the brake fluid level falls considerably be­
low the "MIN" mark, the brake warning/indi­
cator light (U .S . mode ls:
1111 , Canadian
models: .) will come on
<::> page 19 and
<::> page 32. Do not continue to operate the ve­
h icle . The complete brake system should be
thoroughly checked by an authorized Aud i
dea ler or qualified workshop and the cause
corrected. If the brake fluid level is too low,
the brake warning/indicator light will illum i­
nate . Contact an authorized Aud i dealer
im­
m ediatel y.
@ Tips
The brake fluid rese rvoir is located unde r­
neath the cove r.
Changing brake fluid
Hove the broke fluid changed by on experi­
enced technician.
Brake fluid absorbs moisture from the a ir . If
the water content in the brake fluid is too
h igh , corrosion in the brake system may result
after a per iod of t ime. The bo iling po int of the
brake fluid wi ll also decrease considerably and
decrease braking performance.
Therefore, the brake flu id must be changed
e ver y tw o year s. Always use new b rake fluid
which conforms to Federal Motor Vehicle
Standard "FMVSS 1 16 DO T 4".
The brake flu id reservo ir can be difficult to
reach, therefore, we recommend that yo u
have the brake f luid changed by you r author­
ized
Audi dea ler. Your dea ler has the correct
too ls, the right brake fluid and the know -how
to do this for you.
A WARNING
- Brake fluid is poisonous . It must be stor­
ed only i n the closed orig inal container
o ut of the reach of children!
- Brake fa ilure can result from old or inap­
propriate b rake fluid. Observe these pre­
caut ions: -
Use only brake fluid that meets SAE
specification
J 1703 and conforms to
Federa l Motor Vehicle Standard 116.
Always check with your authorized Audi
dealer to make sure you are using the
correct brake fluid . The correct type of
brake f lu id is also ind icated on the
brake flu id reservoir.
- T he brake fluid must be new. Heavy use
of the bra kes ca n cau se a vapo r lock if
the b rake fluid is left in the system too
l ong . This can seriously affect the effi ­
c iency of the brakes as well as your
safety. This co uld resu lt in an accident.
(D Note
Bra ke fluid will damage the paint of you r
vehicle .
(® For the sake of the environment
Because of the p rob lem of p roper disposal
of b ra ke fluid as well as the spec ial too ls
r equired and the necessary expertise, we
re commend that yo u have the brake fluid
changed by yo ur authorized Aud i dea ler.
Battery
General information
U nder normal ope rat ing cond itions, the bat­
tery in yo ur Audi does not need any ma inte­
nance. With
high o utside tempe ra tur es or
l ong dai ly drives we recommend that you have
the e lectrolyte level checked by an authorized
Audi dealer or qualif ied workshop. The elec­
trolyte level should also be checked each time
the battery is charged
<::> page 2 70.
Have the battery checked when yo u take your
vehicle in for service. You are well advised to replace a battery that is o lder than 5 years .
With certain types of airbag deployment, the batte ry is disconnected from the veh icle elec­
trical system for safety reasons¢.&

274 T ire s and wheel s
-Never mount used tires on yo ur vehicle if
you are not sure of their "previous histo­
ry." Old used tires may have been dam­
aged even though the damage cannot be
seen that can lead to sudden t ire failure
and loss of vehicle control.
- If you notice unusual vibration or if the
vehicle pulls to one side when driving, al­
ways stop as soon as it is safe to do so
and check the wheels and tires for dam­
age.

are designed for the cond itions that are
Glossary of tire and loading terminology
Accessory weight
means t he comb ined we ight (in excess of
those sta ndard items which may be rep laced)
of au toma tic tra nsmission, power steer ing,
power brakes, power windows, power seats,
radio, and heater, to the extent that th ese
items are availab le as factory -installed equip­
ment (whether installed or not) .
Aspect ratio
means t he ratio of the he ight to the w idth of
the tire in percent . Numbers of 55 or lower in ­
dicate a low sidewall for improved steering re­
sponse and better overall handling on dry pavement .
Bead
means the part of the ti re that is made of
steel wires, wrapped or reinforced by ply cords
