A WARNING
--- Never rely exclusively on the outside
temperature display to determine if a
road surface is icy or not. Keep in mind
that road surfaces, especially br idges
and overpasses, could be ice covered and
slippery even at an outside temperature
above 41 °F (+5 °C).

specia l care in cold weather cond itions
when the chance of encountering icy
road surfaces increases.
¢j) Tips
If the vehicle is stationary, or if you are
driving at a very low speed, the tempera­
ture shown in the display might be s light ly
higher than the actual outs ide tempera­
ture. This i.s caused by the heat being radi­
ated from the engine .

On the road
Steering
Manually adjustable steering wheel
The steering wheel position is fully adjustable
up and down and forward and back .
Fig. 87 Lever under the stee ring column
First, adjust the driver's seat correctly.
• Pull the lever
¢fig . 87 ¢ Lo,.
• Move the steering wheel to the desired po­
s it ion.
• Push the lever against the steering col umn
u ntil it locks.
There must be at least 10 inches (25 cm) be­
tween your chest and the center of the stee~
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 peda ls and increase the distance
from the steering wheel.
F or detailed information on how to adjust the
driver's seat, see
¢ page 62.
& WARNING
Improper use of steering wheel adjust­
ment and improper seating position can
cause serious personal injury .
- Adjust the steering whee l co lumn on ly
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¢
fig. 132. If you cannot
On th e road 7 5
maintain this minimum distance, the air­
bag system cannot protect you properly.
- If physical limitations prevent you from
sitting 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 aligned with your
face, the supplementa l driver's a irbag
cannot provide as much protection in an
accident . Always make sure that the
steer ing whee l is al igned w ith your
chest .
- Always hold the steer ing whee l w ith your
hands at the 9 o'clock and 3 o'clock posi­
tions to reduce the risk of persona l injury
if the driver's airbag dep loys .
- Never hold the stee ring wheel at the 12
o'clock position or wi th your hands inside
the stee rin g wheel rim or on the steering
wheel hub. Holding the steering wheel

tions by hand

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.
Vehicles with multitronic transmission : Your
vehicle is equipped with
hill hold assist allow­
ing you to start while on an incline. The sys­
tem is activated when the brake pedal is
pressed down and held
for a few seconds. The
brake p ressure will hold for a moment after
the brake pedal loosens to prevent the vehicle
from rolling backwards while starting up.
A WARNING
-The vehicle can also roll when the engine
is stopped.
- Unintended vehicle movement can cause
serious injury.
- Never leave your vehicle with the engine
running while in gear. If you must leave
your vehicle when the engine is running,
activate the parking brake 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 "creeping", you
must keep your foot on the brake when
the engine is running and the selector
lever is in D/S or R or "tiptronic" mode is
selected.
- Do not press the accelerator pedal when
changing the selector 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 brake
pedal too often or too long when driving
down a hill. Constant braking causes the
brakes to overheat and substantially re ­
duces braking performance, increases
Transmission 89
braking distance or causes complete fail­
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.
- 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 lamo
[O] illu­
minates and a driver message appears
¢ page 92 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 set
¢ page 205, Engine compartment. Oth­
erwise, any increase in engine speed may
set the vehicle in motion, even with the parking brake applied.
(D Note
- S tronic ®- and tiptronic transmission:
When stopping on an incline, do not try
to hold the vehicle in place by pressing
the accelerator pedal while a driving gear
is selected. This can cause the transmis ­
sion to overheat and can damage it. Acti­
vate the parking brake or press the brake
pedal to prevent the vehicle from rolling .
- S tronic ®- and tiptronic transmission: Al­
lowing the vehicle to roll when the en­
gine is stopped and the selector lever is
in N will damage the transmission be­
cause it is not lubricated under those cir­
cumstances.
(D Tips
For safety reasons, the parking brake is re­
leased automatically only when the driv­
er's safety belt is engaged in the buckle.
