Additional information
The engine will switch off in the P, D, N and S po­
sitions as well as in manual mode. In the P posi­
tion , the engine will also remain off if you take
your foot off the brake pedal. The eng ine starts
again when you select another selector lever po­
sition and take your foot off the brake pedal.
If you select the R position during a Stop phase,
the engine will start again.
Shift from D to P quickly to prevent the engine
from starting unintentionally when shifting
through R.
You can determine for yourself if the engine will
stop or not by reducing or increasing the amount
of force you use to press the brake pedal. For ex­
ample , if you only light ly press on the brake ped­
al in stop-and and-go traffic or when turning, the
engine will not switch off when the vehicle is sta-
86
tionary. As soon as you press the brake down
harder, the engine will switch off.

- The radar sensor's function and range can
be reduced by rain, snow and heavy spray.
Moving veh icles up ahead may not be
promptly detected or may not be detected
at all .
- Reflective surfaces including crash barriers
or tunnel entrances may impair the funct ion
of the radar sensor.

Hill descent control is activated when the selec­
tor lever is in D/S and you press the brake pedal.

conditions are unfavorable - particularly when
going downhill.
Red uce veh icle speed
imm ediatel y if the tra ile r
shows the s lightest sign of swaying.
Do not try
to stop the sway in g b y accele rating .
Observe speed lim its . In some areas, speeds for
ve hicl es towing tra ilers are lower than for reg ula r
veh icles.
A lways apply brakes early . When dr iving down­
h ill , sh ift into a lower gear to use the engine
b raking effect to slow the veh icle. Use of the
brakes a lone can cause them to overheat and fail.
Air suspension*
When driving with a tra iler, activate the trailer
mode of the air suspension . Switch the air sus­
pens ion tra iler mode on when you a re towing a
tra ile r. This will limit the regulat ion by the air
suspens ion while driving . Select in the MM I:

Coolant temperature
The coolan t temperature gauge¢ page 10 must
be observed carefully. The coo lant temperature
can increase if you drive on long inclines in a low

A WARNING
Anyone not properly restrained in a moving
vehicle is at a much greater risk in an acci­
dent. Never let anyone ride in your car who is
not properly wearing the restraints provided
by Audi.
Trailer mode notes
Important to know
Your vehicle hand les different ly when towing a
trai ler because of the additiona l weight and dif­
ferent weight distr ibut ion. Safety, performance
204
-
and economy will g reatly depend on how carefu l­
l y you load your trai ler and operate your rig .
Befo re yo u actually tow yo ur t railer, pract ice
turning, stopping and backing up in an area away
from traffic. Keep practicing unti l you have be ­
come complete ly familiar with the way your vehi­
cle-tra iler combination behaves and responds .
Backing up is diff icult and requ ires practice.
Backing up with a trailer genera lly req uires steer ­
ing action opposite to that when backing up your
vehicle witho ut a trailer .
Maintain a greater distance between yo ur vehicle
and the one in front of you. You will need more
room to stop . To compensate for the trailer, you
will need a larger than normal turning radius .
When passing, remember tha t you canno t accel­
erate as fast as you normally wou ld because of
the added load . Make sure you have enough room
to pass. After passing, allow p lenty of room for
your trailer before changing lanes again.
Avoid jerky starts, sharp turns or rapid lane changes.
(D Tips
- Do not tow a trailer du ring the break-i n pe ri­
od of your vehicle.
- If you tow a tr aile r, your A udi may requi re
more frequent ma intenance due to the ex­
tra load ¢
page 281.
Parking on a slope
Do not park on a slope with a trailer . If it cannot
be avoided, do so only after doing the following:
When parking:
.,. App ly the foot brake.
.,. Have someone p lace chocks unde r both the ve­
hicle and the trailer wheels .
.,. With chocks in place, slowly release the brakes
until the wheel chocks abso rb the load .
.,. Turn the whee ls towards the curb.
.,. App ly the parking brake .
.,. Select the P selector lever posit ion.
