2012 AUDI A8 ignition

- the temperature in the luggage compart­
ment is below 131 °f (55 °C). The cooler
switches off automatically if the tempera­
ture in the luggage compartment exceeds
131 °f (55 °C) . Once the temperature falls
below 131 °f (55 °C) again, the cooler
switches on aga in automatically .
- the battery is adequately charged . The cool­
er switches off automatically if the vehicle
battery voltage falls below a minimum lev­
el. This prevents the battery from discha rg­
i ng . The cooler switches back on again auto­
matically when the battery voltage increases
again (e.g . after starting the engine).
The cooler cools to 42.8 °f
(+ 6 °C) and the
freezer cools to 21.2 °f (-6 °C) in opt imum
cooling cond itions . Th e cooling performance
is affected by the temperature in the luggage
compartment. The temperature inside the
cooler will be higher if the luggage compart­
ment is hot.
A WARNING
To avoid putting the occupants at any risk,
please observe the following safety rules:
- The maximum capacity is 2.5 kg (5.5
lbs.).
- Never overload the cooler. This could
cause injury in the event of a collision or
sudden braking.
- The coo ler lid must always be kept closed
while you are driving. Make sure the re­
taining catch is securely engaged. The
contents of the coo ler could be thrown
forward into the passenger compart­
ment in the event of a collision or under
sudden braking - risk of injury!
- Inflammable liquids, gas canisters, etc.
must not be stored in the cooler -risk of
exp losion! This also includes any prod­
ucts that might emit volatile or inflam­
mable gases.
- Liquids will freeze at temperatures at or
below 32 °f (0 °C) and may cause glass
bottles to burst!

On the road
Steering
Adjusting steering wheel position
The steering wheel position can be adjusted
for height and reach .
Fig. 80 Switch for steer ing w heel adjustment
First, adjust the driver's seat correctly.
• To adjust the height, press the switch up/
down . The steering column will continue
moving as long as you are pressing the
switch.
• To move the steering wheel forward or
back, press the switch forward/back. The
steering column will continue moving as long as you are pressing the switch.
There must be at least 10 inches (25 cm) be­
tween your chest and the center of the steer­ ing wheel. If you cannot sit more than 10 in­
ches (25 cm) from the steering wheel, see if
adaptive equipment is available to help you
reach the pedals and increase the distance
from the steering wheel.
For detailed information on how to adjust the
driver's sea t, see
Q page 55.
In vehicles with the memory function*, the
steering column settings are stored together
with the seat position .
A WARNING
Improper use of steering wheel adjust­
ment and improper seating position can
cause serious personal injury.
-
On the road 79
-Adjust the steering wheel column only
when the vehicle is not moving to pre­
vent loss of vehicle control.
- Adjust the driver 's seat or steering wheel
so that there is a minimum of 10 inches (25 cm) between your chest and the
steering wheel
~ page 125, fig . 133 . If
you cannot maintain th is m inimum dis­
tance, the airbag system cannot protect
you properly.
- If physical limitations prevent you from
sitt ing 10 inches (25 cm) or more from
the steering wheel, check with your au­
thorized Audi dealer to see if adaptive
equipment is available .
- If the steering wheel is al igned with yo ur
face, the supplementa l driver's airbag
cannot provide as much protection in an
accident. Always make sure that the
steering whee l is aligned with your
chest.
- Always hold the steering whee l with your
hands at the 9 o'clock and 3 o'clock posi­
tions to reduce the risk of personal injury
if the driver's airbag deploys.
- Never hold the steering wheel at the 12
o'clock position or with your hands inside
the steering wheel rim or on the steering
wheel hub. Holding the steering wheel
the wrong way can cause serious injuries
to the hands, arms and head if the driv­
er's airbag deploys.

@ Tips
-You can apply the parking brake at any
time - even w ith the ignition switched
off. The ignit ion must be on in order to
release the parking brake.
- Occasiona l noises when the park ing

brake goes through a self-test cycle at
regular intervals. Any assoc iated noises
are norma l.

hicle from rolling away accidentally.
P a rking
~ Stop the vehicle w ith the foot brake.
~ Pu ll the switch© to apply the parking

nates the tendency to creep w ith a dr ive range
engaged. As soon as you drive off as usua l,
the parking brake is released automatically
and the vehicle starts to move.
St arting on slope s
When starting on inclines, the sta rting assist
prevents the vehicle from unintentionally roll­
ing back. The braking force of the parking
brake is not re leased until suff ic ient driving
force has been built up at the wheels.
(D Tips
For safety reasons, the parking brake is re­
l eased automatically on ly when the driv­
er's safety belt is engaged in the buckle.
