Malfunction in the brake system
If the brake warning light¢ page 14 and the ABS
warning illuminate
together there may be a mal­
function in the ABS, and there may also be a mal­
function in the brake system itself¢.&. .
The ABS
will not work and you will notice a change in
braking response and performance.

thorized Audi dealer as soon as possible.
A WARNING
- If the 9 (USA models)/ll] (Canada mod­

comes on while driving, the ABS system is
not working properly. The vehicle can then
be stopped only with the standard brakes
(without ABS). You will not have the protec­
tion ABS provides. Contact your Audi dealer
as soon as possible.
- USA models: If the 1111 warning light, the
DJ warning light and the 9warning light
come on together, the rear wheels could
lock up first under hard braking. Rear wheel
lock-up can cause loss of vehicle control and
an accident. Have your vehicle repaired im­
mediately by your authorized Audi dealer or
a qualified workshop. Drive slowly and avoid
sudden, hard brake applications.

_& WARNING
--Never rely exclusively on the outside tem­
perature display to determine if a road sur­
face is icy or not. Keep in mind that road
surfaces, especially bridges and overpasses,
could be ice covered and slippery even at an
outside temperat ure above 41 °F (+S °C).
- Always reduce your speed and dr ive with
special care in cold weather conditions when
the chance of encountering icy road surfaces increases .
(D Tips
-You can select the units used for tempera­
ture, speed and other measurements in the
MMI.
- If the vehicle is stationary, or if you are driv­
ing at a very low speed, the temperature
shown in the display might be slightly high­
er than the actual outside temperature . This
is caused by the heat being radiated from
the engine .

'SI: .... .... Starting off with a trailer
To prevent rolling back unintentionally on an in­
cline, do the following:
11-Keep the sw itch<®) pulled and depress the ac­
celerator. The parking brake stays applied and
prevents the vehicle from rolling backward .
11-You can release the switch© once you are su re
that you a re deve loping enough forwa rd mo­
mentum at the whee ls as you depress the ac­
celerator .
Depending on the weight of the rig (vehicle and
trailer) and the seve rity of the incline, you may
roll backwards as you start. You can prevent roll­
ing backwards by holding the parking brake
switch C®> pulled out and accelerating -just as
you would when starting on a hill with a conven­
tional hand brake.
Emergency braking
In the event that the conventional brake system
fails or locks.
11-In an emergency, pull the sw itch<®) and contin­
ue to pull it to s low your vehicle down with the
parking brake.
11-As soon as you release the switch © or acceler-
ate, the brak ing process stops.
If you pull the switch<®> and hold it above a
speed of about 5 mph (8 km/h), the emergency
braking function is in itiated. The vehicle is braked
at all four wheels by activating the hydrau lic
brake system . The brake performance is sim ilar
to making an emergency stop¢,& .
In order not to activate the emergency brak ing by
mistake, an audib le warning tone (bu zzer)
sounds when the sw itch(®) is pu lled . As soon as
the switch(®) is released, or the accelerator pedal
i s depressed, emergency braking stops .
A WARNING
Emergency braking should only be used in an
emergency, when the normal foot brake has
fai led or the brake pedal is obstructed. Using
t he parking brake to perform emergency
braking will slow your vehicle down as if you
D riving
had made a full brake applicat ion . The laws of
physics cannot be suspended even with ESC
and its associated components (ABS, ASR,
EDL). In corners and when road or weather
conditions are bad, a full brake application
can cause the vehicle to skid or the rear end to
b reak away -risking an acc ident.
Start/Stop system
Description
Applies to: vehicles with Start-Stop-System
The Start-Stop -System can help increase fuel
economy and reduce CO2 emissions.
In the Start-Stop-mode, the engine shuts off au­
tomatica lly when the vehicle is stopped, such as
at a traffic light . The ign ition remains switched
on during this stop phase. The eng ine will be au­
tomat ically restarted when needed.
The last Start-Stop-System setting (on/off using
the b utton
10 -I) will be restored when the igni­
t ion is turned on. The LED in the
10 ~1 button turns
on when the Start-Stop-System is switched off
manually .
Basic requirements for the Start-Stop mode
-The driver's door is closed.
- The driver' seat belt is latched .
- The hood is closed.
- The vehicle must have bee n driven faster than
2.5 mph (4 km/h) since the last stop.
- A trailer is not hitched to the vehicle .
A WARNING
-
-Never let the vehicle roll with the engine
switched off. You could lose contro l over the
veh icle. Th is can lead to a collision and seri­
ous injuries .
- The brake booster and the steering support
do not work while the engine is switched
off . More force is required to stop and to
steer the vehicle.
- To reduce the risk of injur ies, ma ke sure that
the Sta rt-Stop-System is turned off when
working in the engine compartment
¢page 87.
85

-Never place or install floor mats or other
floor coverings on top of already installed
floor mats. Additional floor mats and other
coverings will reduce the size of the pedal
area and interfere with the pedals .
- Always properly reinstall and secure floor
mats that have been taken out for cleaning.
- Always make sure that objects cannot fall
into the driver footwell while the vehicle is
moving . Objects can become trapped under
the brake pedal and accelerator pedal caus­ ing a loss of veh icle control.
Storing cargo correctly
Loading the luggage compartment
All luggage and other objects must be properly
stowed and secured in the luggage compart­
ment.
L oose items in the luggage compartment can
shift suddenly, changing vehicle handling charac­
teristics. Loose items can also increase the risk of
serious personal injury in a sudden vehicle ma­
neuver or in a collision.
.. Distribute the load evenly in the luggage com­
partment.
.. Always place and properly secure heavy items in
the luggage compartment as far forward as
possible.
.,. Secure luggage items using the tie-downs pro­
vided
¢ page 68, Luggage compartment .
A WARNING
Improperly stored luggage or other items can
fly through the vehicle causing serious per­
sonal injury in the event of hard braking or an
accident. To help reduce the risk of serious
personal injury:
- Always put objects, for example, luggage or
other heavy items in the luggage compart­
ment.
- Always secure objects in the luggage com­
partment using the tie-down hooks and
suitable straps .
Driving safety
A WARNING
Heavy loads will influence the way your vehi­
cle handles. To help reduce the risk of a loss
of control lead ing to serious personal injury:
- Always keep in m ind when transporting
heavy objects, that a change in the center of
gravity can also cause changes in vehicle handling:
- Always distribute the load as evenly as
possible .
- Place heavy objects as far forward in the
luggage compartment as possible.
- Never exceed the Gross Axle Weight Rating
or the Gross Vehicle Weight Rating specified
on the safety compliance sticker on the left
door jamb. Exceeding permissible weight
standards can cause the vehicle to slide and handle differently.
- Please observe information on safe driving
¢page 129.
A WARNING
To help prevent poisonous exhaust gas from
being drawn into the vehicle, always keep the
rear lid closed while driving .
- Never transport objects larger than those
f itting completely into the luggage area be­
cause the rear lid cannot be fully closed.
- If you absolutely must drive with the rear lid open, observe the following notes to reduce
the risk of poisoning:
- Close all windows,
- Close the power roof,
- Open all air outlets in the instrument pan-
el,
- Switch off the air recirculation
,
- Set the fresh air fan to the highest speed .
A WARNING
Always make sure that the doors, all win­
dows, the power roof and the rear lid are se­
curely closed and locked to reduce the r isk of
in jury when the vehicle is not being used.
- After closing the rear lid, always make sure
that it is properly closed and locked.
