larly not children should remain in the vehi­
cle. Locked doors make it more diff icu lt for
emergency workers to get into the vehicle -
putt ing lives at risk.
Starting from rest
The starting assist function ensures that the
parking brake is released automatically upon
starting .
Stopping and applying parking brake
~ Pull the switch @9 page 76, fig. 91 to apply
the parking brake.
Starting and automatically releasing the
parking brake
~ When you start to drive as usual, the parking
brake is automatica lly released and your vehicle
begins to move.
When stopping at a traffic signal or stopping in
city traffic on vehicles w ith an automatic trans­
miss ion, the park ing brake can be applied. The
vehicle does not have to be held with the foot­ brake . The park ing brake eliminates the tendency
to creep with a drive range engaged. As soo n as
you dr ive off as usual, the parking brake is re­
leased automatically and the veh icle starts to
move.
Starting on slopes
When starting on inclines, the start ing assist pre ­
vents the vehicle from unintentionally rolling
back. The braking force of the parking brake is
not released until sufficient driving force has
been built up at the wheels.
(D Tips
For safety reasons, the parking brake is re­
leased automatically only when the driver's
safety belt is engaged in the buckle.
Driving
Starting off with a trailer
To prevent rolling back unintentionally on an in­
cline, do the following:
~ Keep the switch @9 page 76, fig. 91 pulled
and depress the accelerator. The parking brake
stays applied and prevents the vehicle from
rolling backwa rd .
~ You ca n release the sw itch @once you a re sure
that you are develop ing enough dr iv in g force at
t he wheels by depressing the accelerator.
Depending on the weight of the rig (vehicle and
trailer) and the severity of the incline, you may
roll backwards as you start. You can prevent roll­
i ng backwards by holding the pa rking brake
swi tch @ pulled out and accelerating -just as
you wou ld when starting on a hill with a conven­
t iona l hand brake .
Emergency braking
In the event that the conventional broke system
foils or locks.
~ I n an emergency, pull the switch@Q page 76,
fig. 91 and continue to pull it to slow your vehi ­
cle down with the parking brake.
~ As soon as you re lease the switch @or acceler-
ate, the braking process stops .
If you pull the switch @and hold it above a
speed of about 5 mph (8 km/h), the emergency
braking f unction is init iated. The vehicle is braked
at all four whee ls by activating the hydraulic
brake system . The brake performance is s imilar
to making an emergency stop
Q .& .
In order not to activate the emergency braking by
mistake, an audible warning tone (buzzer)
sounds when the switch @is pulled . 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 bra ke has
failed or the brake pedal is obstructed. Using
the parking brake to perform emergency
braking w ill slow your vehicle down as if you

Winter tires
When dr iving in the winter, yo ur vehicle with all­
whee l dr ive has a n advantage, even with regu la r
t ir es. In w inte r road cond it ions i t may be advisa­
ble to mo unt win ter tires (o r all-se ason tires) for
i mproved driveability an d braking: these ti res
must be mo unted on
all four whee ls. See also

Tire chains
Where tire ch ains are mandatory on certain
r oads, t his normally also applies to vehicles wi th

h icle normal load.
New tires or wheels
Audi recommends having all work
on tires or wheels performed by
an authorized Audi dealer or au­
thor ized Audi Service Facility.
These facilit ies have the proper
knowledge and are equipped with
the required tools and replace­ ment parts.
.,. New tires do not yet have the
optimum gripping properties .
Drive carefully and at moderate
speeds for the first 350 miles
(500 km) with new tires.
1>-Use ti res of the same construc­
tion , size (rolling circumference)
and as close to the same tread
pattern as possible on all four
wheels.
1>-0o not replace tires individually.
At least replace both tires on the
same axle at the same time.
1>-Audi recommends that you use
Audi Original Tires. If you would like to use different tires, please
note that the tires may perform
differently even if they are the
same size ¢
.&..

1>-Ifyou would like to equip your
vehicle with a tire/rim combina­
tion that is different from what
was installed at the factory, con­
sult with an authorized Audi
dealer or authorized Audi Service Facility before making a pur­
chase ¢,&. .
The spare tire* is different from
the regular tires installed on the
vehicle -for example, if winter
tires or wide tires are installed -
so only use the spare tire* tempo­
rarily in case of emergency and
drive carefully while it is in use. It
should be replaced with a regular
tire as soon as possible.
On
all wheel drive vehicles, all
four wheels must be equipped
with tires that are the same brand and have the same construction
and tread pattern so that the
drive system is not damaged by
different tire speeds . For this rea­
son, in case of emergency , only
use a spare tire* that is the same
circumference as the regular
tires.
! WARNING
- Only use tire/rim combina­
tions and suitable wheel bolts
that have been approved by .,.

Wheels
and a special procedure. You must not repair or
disassemble them¢&. .
A WARNING
Wheel bolts that are tightened or repaired in­
correctly can become loose and result in loss
of vehicle control, which increases the risk of
an accident. For the correct t ightening specifi ­
cation, see ¢
page 229, After changing a
wheel .
-Always keep the wheel bolts and the
threads in the wheel hub clean and free of
grease.
- Only use wheel bolts that fit the rim .
- Always have damaged rims repaired by an
authorized Audi dealer or authorized Aud i
Service Facility . Never repair or disassemble
rims yourself, because this inc reases the risk
of an accident.
Winter tires
Winter tires s ignificantly improve the vehicle's
handling when driving in winter conditions . Be­
cause of their construction (width, compound,
tread pattern), summer tires provide l ess trac­
tion on ice and snow.
.,. Use winter tires on all four wheels.
.,. Only use winter tires that are approved for your
vehicle.
.,. Please note that the maximum permitted
speed may be lower with winter tires
q .&,. . An
authori zed Audi dealer or authori zed Audi Serv­
ice Facility can inform you about the maximum
permitted speed for your tires .
.,. Check the tire pressure after install ing wheels
q page 217.
The effectiveness of winter tires is reduced great­
ly when the tread is worn down to a depth of
0 .157 inch (4 mm). The character istics of winter
tires also decrease greatly as the tire ages, re­
gardless of the remaining tread.
A WARNING
- Never drive faster than the maximum per­
mitted speed for your tires. This could cause
the tires to heat up too much. This increases
222
-
the risk of an accident because it can cause
the tire to burst.
- Always adapt your driving to the road and
traffic conditions . Drive carefully and reduce
your speed on icy or slippery roads . Even
winter tires can lose traction on black ice .
@ For the sake of the environment
Reinstall summer tires at the appropriate
time, because they prov ide better handling
when roads are free of snow and ice. Summer
tires cause less road noise, tire wear and fuel
consumpt ion .
(D Tips
You can also use all season tires instead of
winter tires. Please note that in some coun­
tries where winter tires are required, only
winter tires w ith the ~ symbol may be per­
mitted.
Snow chains
Snow chains improve traction in the snow .
.,. Only install snow chains on the front wheels.
This applies also to vehicles with all wheel
drive* .
.,. Check and correct the seating of the snow
chains if necessary after driving a few feet. Fol­
low the instructions from the manufacturer.
.,. Note the maximum permitted speed when dr iv­
ing with snow chains. Do not exceed 30 mph (SO km/h).
Snow cha ins not only improve the
driving in win­
ter road conditions, but also the
braking .
Use of snow chains is only permitted with certain
rim/tire combinat ions due to technical reasons .
Check with an author ized Audi dealer or author­
ized Audi Service Facility to see if you may use
snow chains.
Use
fine-mesh snow chains. They must not add
more than 0.53 inch (13.5 mm) in height, includ­
ing the chain lock.
You must remove the chains when driving on
roads that are
free of snow . When roads are free ..,.
