2012 AUDI Q7 engine

-The brake booster and servotronic only
work when the engine is running. With
the ignition turned off, you have to apply
more force when steering or braking .
S ince you cannot steer and stop normal­
ly, this can lead to accidents and ser ious
injuries.
- The rad iator fan can continue to run for
up to 10 min utes even after you have
turned off the engine and removed the ign ition key. The radiator fan can also
turn on again if the engine coolant heats
up because of intense sunlight or heat
build -up in the engine compartment.
«I) Note
Do not stop the engine immed iate ly after
hard or extended dr iving. Keep the engine
running for approximately two minutes to
prevent excessive heat build-up .

The parking brake warning light. (USA)/ .
(CON) illuminates when the parking brake is
set and you switch on the ignition.
_& 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
To prevent a parked vehicle from rolling
away, there are a few things you should do .
When you park your vehicle, do the
following
• Stop the vehicle using the brake pedal.
• Apply the parking brake firmly .
• Move the selector lever into the
P position
~ &.
• Switch off the engine and remove the igni-
tion key from the ignition lock.
When you park your vehicle on hills, do
the following
• Stop the vehicle using the brake pedal.
• Apply the parking brake firmly.
• If you are parking headed downhill, turn
the front wheels
toward the curb.
• If you are parking headed uphill, turn the
front wheels
away from the curb.
• Move the selector lever into the
P position.
• Switch off the engine and remove the igni­
tion key from the ignition lock.
_& 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.
@ 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 the 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
veh icle 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
brake pedal immediately or engage the
parking brake.
- Should the engine stall, depress the
brake pedal immediately or engage the
parking brake.
- In order to prevent the vehicle from roll­ ing back unintentionally when starting in
stop-and -go traffic, keep the brake pedal
depressed for a few seconds before driv­
ing
off.
- When you leave the vehicle -even if only
briefly -, switch
off the ignition and
make sure to remove the ignition key. Al­
so engage the
parking brake to prevent
your vehicle from rolling unintentionally. This particularly applies if ch ildren are
left in the veh icle -danger of acc ident!
