- The hood must be closed .
- The vehicle must have driven faster than
2 mph
(3 km/h) since the last time it stopped .
- A trailer must not be hitched to the vehicle .
If you leave the vehicle during a stop phase, the
engine can be restarted within approximately 30
seconds if the following requirements are met:
- The driver's door must be closed , the driver
must be wearing the safety belt and the brake
pedal must be pressed . Or:
- The driver's door must be closed, the brake
pedal must be pressed and a gear must be se­
lected.

Driving
A WARNING
-Always adapt your driving to the traffic flow.
- Only use the Launch control program when
road and traffic conditions allow it and oth­
er drivers will not be endangered or both­
ered by your driving and the vehicle's accel­
eration.
- Please note that the drive wheels can spin
and the vehicle can break away when sport
mode is switched on, especially when the
road is slippery.
- Once the vehicle has started moving, press
the
1 .$ OFFI button briefly to turn the sport
mode off.
(D Tips
- The transmission temperature may increase
significantly after using the launch control
program. If that happens, the program may
not be available for a few minutes. It will be
available again after a cool-down period.
- When accelerating using the launch control
program, all vehicle parts are subject to
heavy loads. This can lead to increased
wear.

f late trai ler tires to trailer and tire manufactur­
ers' specifications.
Lights
The headlight settings should be checked with
the trailer attached before driving off. Check to
make sure both vehicle and trailer lights are
working properly.
Safety chains
Be sure trailer safety chains are properly connect­
ed from the tra iler to the hitch on the vehicle.
L eave enough slack in the chains to permit turn­
ing corners. When you install safety chains, make
sure they wi ll not drag on the road when you are
driving.
The chains shou ld cross under the trailer tongue
to prevent it from dropping in case of separation
from the hitch.
Driver messages
Driving with a trailer requires extra caution .
Weight distribution
Towing a loaded trailer w ith an empty car results
in a high ly unstable dist ribution of weight . If this
cannot be avo ided, drive at very low speeds only
to avoid the risk of losing steering control.
A "balanced" rig is easier to operate and cont rol.
This means that the tow vehicle should be loaded
to the extent possible and permissible, while
keeping th e trailer as light as possib le under the
circumstances . Whenever possib le, transfer
some cargo to the luggage compartment of the
tow vehicle whi le observing tong ue load require­
ments and vehicle loading considerations.
Speed
The higher the speed, the more difficult it be­
comes for the driver to contro l the rig. Do not
drive at the maximum permissible speed. Reduce
your speed even more if load, weather or wind
<( conditions are unfavorable -particularly when a,
;::; going downhill. ,....

3 a,
Trailer towing
Reduce vehicle speed immediately if the trailer
shows the slightest sign of swaying.
Do not try
to stop the swaying by accelerating.
Observe speed limits. In some areas, speeds for
vehicles towing trailers are lower than for regular
vehicles .
Always apply brakes early. When driving down­
hill, shift into a lower gear to use the eng ine
braking effect to slow the vehicle . Use of the
brakes alone can cause them to overheat and fail.
Coolant temperature
T he coolant temperature gauge~ page 11 must
be obse rved carefully. The coolant temperature
can increase if you drive on long inclines in a low
gear at high engine speeds . Reduce your speed
immediately if the LEDs in the top part of the dis­
play turn on.
For more information about indicator lights, re­
fer to.
~ page 31 .
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 Aud i.
Trailer towing
information
Important to know
Your vehicle handles differently when towing a
trailer because of the addit ional weight and dif­
ferent weight distribution . Safety, performance
and economy will greatly depend on how careful­
ly you load your trailer and operate you r rig.
Before you actually tow your trailer, pract ice
turning, stopping and backing up in an area away
from traffic . Keep pract ic ing until you have be­
come complete ly familiar w ith the way your vehi­
cle-trailer combination behaves and responds.

In a speed range under 40 mph (65 km/h), con­
gestion assist can he lp to keep the vehicle within
a lane calculated by the system. Within the limits
of the system, the system controls the steering
automat ica lly when adaptive cruise contro l is
switched on. Since congest ion assist is only a n
ass ist system, the driver must always keep his or
her hands on the steering wheel and be ready to
stee r. The driver can override the control at any
time by actively steering.
The system is designed for driving on express­
ways and highways .
