2014 AUDI Q7 engine overheat

Instrument s and warning /indicator lights 11
too high, or the coolant level is too low
¢ page 32.
If the needle is well in the upper area of the
ga uge , the coolant temperature is too high.
Stop the vehicle , switch the eng ine off and
allow the engine to cool.
If the warning light
comes on again after driving a short distance,
contact an authorized dealer.
A WARNING
- Always observe the warning in
¢
page 257, before opening the hood
and checking the engine coolant level.
- Never open the engine hood if you see or
hear steam, or if you see engine coolant
dr ipping from the engine compartment.
You could bu rn yourself. Let the engine
cool off first until you can no longer see
or hear steam or coolant escaping.
0 Note
- Mount ing additional lights or accessories
i n front of the a ir inlets reduces the cool­
i ng effect of the radiator. At h igh outside
temperatures or high eng ine load , the
engine could overheat.
- The front spo iler has been designed to
properly distribute the cooling air when
the veh icle is moving. If the spoiler is
damaged, this cou ld reduce the cooling
effect and the engine could then over­ heat. Ask your authorized Audi dealer for
ass istance.
Tachometer (engine rev counter)
The tachometer indicates the engine RPM
(revolutions per minutes).
The tachometer @¢ page 10, fig. 3 is the left
of the two large clock-type displays.
The engine turns at a speed 1,000
times the
single digit in the display, e.g . if the needle is
pointing at the "2" the engine is turning at
2,000 RPM.
If engine RPM drops be low 1,500, you should
downshift to the next lower gear. The red area at
the end of the scale indicates maximum
permissible engine RPM after the break-in pe­
riod. Before reaching this area , move these­
lector lever to position D (Drive) or ease your
foot off the accelerator pedal.
(D Note
The tachometer needle should not move
into the red range. If it does, then only for
a very short per iod of t i me. You could
damage your engine by driving at high RPM .
@) For the sake of the environment
Upshifting early saves fuel and reduces en­
gine noise .

You can switch the display from miles to kilo­ meters and vice versa via the MMI. You can
find out more in the MMI manual.
Lower odometer
The lower odometer shows the total number
of mi les (kilometers) driven.
Upper odometer (trip odometer)
The upper odometer shows the tota l number
of mi les (kilometers) driven since you last re­
set the odometer to zero. You can use this od­
ometer when you want to keep track of how many miles (k ilometers) you have driven for a
single trip or errand. The last digit indicates
1/10 of a mile (100 meters).
You can reset the trip odometer to zero by

The parking brake warning light. (USA)/ .
(CON) illuminates when the parking brake is
set and you switch on the ignition.
A WARNING
-
Always release the parking brake com­
pletely. A partially engaged brake will
overheat the rear brakes, reduce their ef­
fectiveness and cause excessive wear. This could lead to brake failure and an accident .
(D Note
Only after the vehicle has come to com­
plete stop, should you firmly set the park­
ing brake and
move the selector lever into
P.
Parking
• Press the brake pedal to stop the vehicle .
• Apply the parking brake firmly
r=,> page 109,
fig. 123 @.
• Move the selector lever to P.
.. Turn the engine off~_& .
.. When on inclines or declines, turn the steer­
ing wheel so that the vehicle will roll into
the curb if it begins to
move.
A WARNING
This is how you can reduce the risk of in­
jury when leaving your vehicle.
- Never park the vehicle where it can come
in contact with dry grass, spilled fuel or
any other flammable materials.
- When parking on hills, always turn the
wheels so that the front wheels will first
roll into the curb, if the vehicle should
start to roll.
- Never allow anyone - especially small
children - to remain in the vehicle when
it is locked. Locked doors make it more
difficult for rescuers to access the pas­
senger compartment in the event of an
emergency. Danger to life!
- Never leave children unsupervised in the
vehicle. Children could release the park­
ing brake or
move the gearshift lever out
-
of gear. The vehicle could start to roll
away and cause an accident.
- No matter what the season is, the tem­
perature in a parked vehicle can reach
dangerous levels.
Q) Note
- Please exercise care when you park your
vehicle in parking areas with parking bar­
riers or curbs. Parking barriers and curbs
vary in height and could damage your
bumper and related components as the
front of your vehicle
moves over a barrier
or curb that is too high, as you park or as
you back out of a parking spot. In order
to be sure that no such damage can oc­
cur, you may wish to stop short of having
the front tires of your car touch the park­
ing barrier or curb.
- Please also exercise exceptional care
when you drive up or down steep ramps
or drive
over curbs or other obstacles, for
which the vehicle is not designed, be­
cause components of th@ vehicle close to
the ground, such as bumper covers,
spoilers and suspension and exhaust sys­
tem components, may become dam­
aged.
Starting on hills
Hill Hold makes it easier to start on hills.
The system is activated when the brake pedal
is depressed
for a few seconds . For this, the
vehicle must be standing in uphill driving di­ rection.
After releasing the brake pedal, the brake power is held for a
brief moment to prevent
the vehicle from rolling back when starting. At
this time, you can easily begin to
move your
vehicle.
A WARNING
- If you did not begin moving immediately
after releasing the brake pedal, under
certain circumstances, the vehicle would
begin to roll backward. Depress the ..,.

Under certain circumstances, such as driving
in the mountains, it may be usefu l to switch
temporarily to the manual shift program in or­
der to adjust the gears to the driving condi­
tions by hand
c::> page 140 .
On slopes, activate the parking brake first and
then move the selector lever to the P position.
This prevents too much stress from being
placed on the locking mechanism.
A WARNING
- Unintended vehicle movement can cause
serious injury.
- Never leave your vehicle with the engine
running while in gear.
If you must leave
your veh icle when the engine is running,
apply the park ing brake firmly and move
the selector lever to P.
- Power is still transmitted to the wheels
when the engine is running at idle. To
prevent the vehicle from "c reeping ", you
must keep your foot on the brake when
the engine is running and the selector
lever is in D, Sor R or "tiptronic" mode is
selected.
- Do not press the accelerator pedal when
changing the se lector lever position
while the vehicle is stationary and the engine is running.
- Never shift into R or P while driving.
- Before driving down a steep slope, re-
duce your speed and shift into a lower
gear with "tiptronic".
- Do not ride the brakes or press the bra ke
pedal too often or too long when driving
down a hi ll. Constant braking causes the
brakes to overheat and substantially re­
duces braking performance, increases braking distance or causes complete fa il·
ure of the brake system.
- To prevent the vehicle from rolling back
when stopping on inclines, always hold it
in place with the brake pedal or parking
brake . .,..

140 Automatic transmission
-Never hold the vehicle on an incline with
a slipping clutch. The clutch opens auto­
matically when it becomes too hot from
the overload. An indicator lamp
[O] illu­
minates and a driver message appears
c!;> page 141 when the clutch is overload­
ed.
- If the engine must remain running, never
have any driving position engaged when
checking under the hood. Make sure the
selector lever has securely engaged and
is locked in P with the parking brake
firmly set¢
page 257. Otherwise, any
increase in engine speed may set the ve­
hicle in motion, even with the parking
brake applied.
(D Note
- When stopping on an incline, do not try
to hold the vehicle in place by pressing
the accelerator peda l while a driving gear
is selected. This can cause the transmis­
sion to overheat and can damage it. Acti­
vate the park ing brake or press the brake
pedal to prevent the vehicle from rolling.
- Allowing the vehicle to roll when the en­
gine is stopped and the selector lever is
in
N will damage the transmiss ion be­
cause it is not lubricated under those cir­
cumstances.
Hill descent control
The hill descent control system assists the
driver when driving down declines.
H ill descent control is activated when these­
lector lever is in D/S and you press the brake
pedal. The transmission automatically selects
a gear that is suitab le for the incline. Hill de­
scent control tries to maintain the speed ach­
ieved at the time of braking, within physical
and technical limitations . It may st ill be nec­
essary to adjust the speed with the brakes.
Hill descent control switches off once the de ­
cline levels out or you press the accelerator pedal. When the speed
is set in the cruise control
system
c!;>page 111, hill descent control is al­
so activated.
A WARNING
--
Hill descent control cannot overcome
physical limitations, so it may not be able
to maintain a constant speed under all
conditions. Always be ready to apply the brakes.

Homelink
Universal remote
control
Description
Applies to vehicles: with Home link
The HomeLink universal remote control can
be programmed with the remote control for
devices that are already present.
With Home Link, you can control devices such
as the garage door, security systems, house
lights , etc. comfortably from the inside of you
vehicle.
Homelink makes it possible for you to rep lace
three different remote controls from devices
in your home with one universal remote. This
feature works for most garage door and exte­
rior door motor signals. Programming the in­
dividual remote control for your remote con ­
trol takes place on the left side of the front bumper. There is a control module attached at
this location .
A one-time programming of the sensor must be performed before you are able to use sys­
tems with Homelink. If the system does not activate after performing the one-time pro­
gramming, check whether the system uses a rolling code
¢ page 163 .
A WARNING
-Never use the Homelink transmitter
with any garage door opener that does
have not the safety stop and reverse fea­
ture as required by federa l safety stand­
ards. This includes any garage door open­
er model manufactured before April 1,
1982.
- A garage door opener which cannot de­
tect an object, signaling the door to stop
and reverse does not meet current feder­
al safety standards . Using a garage door
opener without these features increases
risk of serious injury or death.
Homelink 161
- For safety reasons never release the
parking brake or start the engine while
anyone is standing in front of the vehicle .
- A garage door or an estate gate may
sometimes be set in motion when the
Homelink remote control is being pro­
grammed. If the device is repeatedly ac­
tivated, th is can overstrain motor and
damage its electrical components - an
overheated mo to r i s a fire hazard!
- To avoid possib le injuries or property
damage, please always make abso lutely
certa in that no persons or objects are lo­
cated in the range of motion of any
equipment being operated.

Notice about data
recorded by vehicle
control modules
Your vehicle is not equipped with an Event Da­
ta Recorder (EDR), installed by some manu­
facturers fo r the express purpose of capturing
data for retrieval after an accident or crash
event . EDRs are sometimes ca lled "crash re­
corders".
Some state laws restrict the retr ieval or down­
loading of data stored by EDRs that were in­
stalled in a vehicle for the express purpose of
retrieving data after an accident or crash
event without the owner's consent.
A lthough your vehicle is not equipped with an
EDR, it is equipped with a number of electron­
ic control modules for various vehicle systems
such as, for examp le, engine function, emis­
sion control, as well as for the airbags and
safety belts .
These electronic contro l modules also record
vehicle-related data during normal vehicle op­
eration for diagnostic and repair purposes.
The recording capacity of the electronic con­
trol modules is limited to data (no sound is re­
corded) and only a small amount of data is ac­
tually recorded over a very limited period of
time and stored when a system fault or other
condition is sensed by a control unit. Some of
the data then stored may relate to vehicle
speed, direction, braking as we ll as restraint
system use and performance in the event of a
crash or other condition. Stored data can only
be read and downloaded with special equip­
ment.
Electronic Stabilization
Control (ESC)
Description
The Electronic Stabilization Control (ESC) rein­
forces driver safety. It reduces the risk of slip ­
p ing and improves driving stability. ESC de­
tects cr itical s ituations such as the vehicle oversteering and
understeering or the wheels
spinning . The vehicle is stabilized by applying
the brakes or reducing engine torque . Once
the ESC is active, the indicator light
G1 blinks
in the instrument cluster.
ESC includes the anti-lock brake system (ABS),
brake assist system, anti-slip regulation
(ASR), electronic differential lock (EDL) and
hill descent control.
Anti-lock brake system (ABS)
ABS prevents the whee ls from locking up
when braking. The vehicle can still be steered
even during hard braking. App ly steady pres­
sure to the brake pedal. Do not pump the ped­ al. A pulsing in the brake pedal indicates that
the system is helping you to brake the vehicle .
Brake assist system
The brake assist system can decrease braking
distance. It increases braking power when the
driver presses the brake pedal quickly in emer­
gency situations. You must press and hold the
brake pedal until the situation is over . In
vehicles with adaptive cruise control*, the
brake assist system is more sensitive if the
distance detected to the vehicle ahead is too
small.
Anti-slip regulation (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
sta rt, accelerate and drive up hills.
Electronic differential lock (EDL)
The EDL brakes wheels that are spinning and
transfers the drive power to the other wheels .
This function is available up to about 60 mph
(100 km/h) .
In extreme cases, EDL automatically switches
off to help keep the brake on the braked wheel
from overheat ing. EDL will switch on again au­
tomat ically when conditions have returned to
normal.

228 Intellig ent technol ogy
- Never let the vehicle ro ll to a stop with
the engine shut off.
- 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.
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 sys­
tem senses the road speed and electronically
adjusts powe r assistance to provide comforta­
b le and safe steering response exact ly match­
ed to the vehicle speed.
Power steering w ill not work if the eng ine is
off. As a result, the steering wheel w ill be hard
to turn.
The power steering fluid level is checked dur­
ing the scheduled ma intenance serv ices .
@ Note
If the re is an electronic malfunct ion, ser­
votronic
w ill still function like a conven­
tional power steer ing system, p roviding a
constant steer ing support force that is no
longer proportionate to the vehicle speed .
This is most noticeab le when turning the
steering whee l at low speeds (for examp le
when parking), -more effort will be re­
quired than usual.
- Be aware of the different than usua l
steering response and adjust your steer­ i ng force accord ingly.
- Have the prob lem checked and set right
by an Aud i dealer as soon as possible.
- When the engine is running , never hold
the steering whee l turned all the way to
the right or to the left for longer than
15
seconds . The power steer ing pump w ill
overheat the hydraulic flu id if you keep holding the steering wheel turned all the
way . This is likely to damage the power
steering system.
- If the powe r stee ring system sho uld fail
entirely, or if the engine is not running
(for example, whi le be ing towed), you
will still be able to steer the ve hicle.
However,
considerably more effort will
be required to do so .
- If the power steering system should
have a leak, or is not functioning proper­
ly, contact your author ized Audi dealer
immediately .
- The power steering system requ ires a
specially formulated hyd ra ulic fluid . The
powe r stee ring reservoir is the one locat­
ed farthest to the rear on the left s ide of
the engine comp artment r=;,
page 259.
T he correct fluid level in the reservoir is
important for proper functioning of the
power steering .
Driving with your
quattro
With all-wheel drive , all four wheels are driv­
en .
Gen eral information
With all-wheel drive, power is distributed to
all four wheels. This happens au toma tically
depending on your driving style and the road
condit ions at the time . See also r=;,
page 224 .
Winter tire s
When driving in the winter, yo ur vehicle with
a ll-wheel drive has an advantage, even wi th
regular tires . In winter road conditions it may
be advisable to mount winter tires (or all -sea ­
son tires) for improved dr iveability and brak­
ing : these tires must be mounted o n
all four
wheels. See also r=;, page 288, Winter tires.
Tire chains
Where tire chains are mandatory on certain
roads, this normally also appl ies to veh icles
with all-wheel driver=;,
page 289, Snow
chains .
