General information
Breaking in
A new vehicle must be broken in for the first 1,000 mi les (1,500 km). Do not drive at speeds
that will exceed 2/3 of the maximum perm itted
engine speed (RPM) for the first 600 miles
(1,000 km), and avoid full acceleration during
this period . You may gradually start increasing
the RPM and the speed between 600 miles (1,000 km) and 1,000 miles (1,500 km) .
During the first hours of use, the engine has a
h igher internal friction than later on when all
moving parts have settled into place with each
other.
How the vehicle is driven during the first 1,000
miles (1,500 km) also affects the engine quality.
Drive at moderate engine speeds after the initial
break-in period, particularly when running a cold
engine. This will reduce engine wear and improve
the mileage .
Do not drive at too low of an engine speed (RPM) .
Shift down if the engine stops running "smooth­ ly". Extremely high engine speeds are automati­
cally reduced .
Reducing the risk of vehicle damage
(D Note
When driving on poor roads, by curbs and on
steep ramps, make su re that low-hang ing
components such as the spoi ler and exhaust
system do not come into contact with these
or they could be damaged. This especially ap­
plies to vehicles with low ground clearance
and vehicles that are heavily loaded.
Driving through water on roads
Note the following to reduce the risk of vehicle
damage when driv ing through water, for example
on flooded roads:
-The water must not be any higher than the bot­
tom of the vehicle body .
86
-Do not drive faster than walking speed .
A WARNING
After driving through water or mud, the effec­
tiveness of the brakes may be reduced due to
moisture on the brake rotors and brake pads.
A few careful brake applications should dry
off the brakes and restore the full braking ef­
fect .
{CT) Note
-Vehicle components such as the engine,
transmission, suspension or electrical sys-
tem can be severely damaged by driving
through water .
-Always switch the Start/Stop system* off
when driving through water <=:>page
91.
@ Tips
-Determine the depth before driving through
water.
-Do not stop the vehicle, drive in reverse or
switch the engine off when driving through
water .
'
-Keep in mind that oncoming vehicles may
create waves that raise the water level and
make it too deep for your vehicle to drive
through safe ly .
-Avoid driving through salt water, because
this can cause corrosion .
Economical and environmentally -friendly
dr iving
The amount of fuel consumption, the environ­
mental impact and the wear to the engine,
brakes and tires depends mostly on your driving
style. With an anticipatory and economic driving
style, fuel consumption can be reduced by ap­ proximately 10-15%. The following tips will help
you conserve the environment and your money at the same time .
Anticipatory driving
A vehicle uses the most fuel when accelerating.
When you drive with anticipation, you do not need to brake as often and so you accelerate less.
When possible, let your vehicle coast with a gear

Assistance systems
General information
Applies to: ve hicles w ith Aud i adapt ive cruise co ntro l
Fig. 112 Fro nt of th e ve hicle: senso rs an d video camera
The areas with the radar and ultrasonic sensors
and the video camera ¢
fig. 112 must not be cov ­
ered by stickers, deposits or any other objects ,
because this can interfere with the adaptive
cruise control function. For information on clean­
ing, see
c::> page 362 . The same applies for any
modifications made in the front area .
In some driving situations , the adaptive cruise
control function is restricted :
-Vehicles can only be detected when they are
within the sensor detection zones
<:;> page 113,
fig. 111 .
-The system has a limited ability to detect
vehicles that are a short distance ahead, off to
the side of your vehicle or moving into your
lane.
-Objects that are difficu lt to detect such as mo­
torcycles, vehicles with high ground clearance
or an overhanging load are detected late or not
detected at all.
-When driving through curves
c::>page 115 .
-When the vehicle is stationary <:;> page 115.
_& WARNING
Always pay attention to the traffic around you
when adaptive cruise control is switched on.
As the driver, you are still responsible for your
own speed and the distance to other vehicles.
The adaptive cruise control is used to assist
you. The driver must always take action to
avoid a collision. The driver is always responsi­
ble for braking at the correct time.
114
-For safety reasons, do not use adaptive
cruise control when the road surface is in
poor condition and/or in bad weather condi­
tions (such as ice, fog, gravel, heavy rain and
hydroplaning) . Using the system under
these conditions increases the risk of an ac­
cident.
- Switch adaptive cruise control off tempora­
rily when driving in turning lanes, on ex­
pressway exits (except if predictive control
is switched on) or in construction zones.
This prevents the vehicle from accelerating
to the stored speed when in these situa­
tions.
-The adaptive cruise control system will not
brake by itself if you put your foot on the ac­
celerator pedal. Doing so can override the
speed and distance regulation.
-When approaching stationary obstacles
such as stopped traffic, adaptive cruise con­
trol will respond with limited function .
- Adaptive cruise control does not respond to
people, animals, or crossing or oncoming
objects.
-The function of the radar sensors can be af­
fected by reflective objects such as guard rails, the entrance to a tunnel, heavy rain or
ice .
(D Note
The sensors can be displaced by impacts or damage to the bumper, wheel housing and underbody. This can impair the adaptive
cruise control. Have an authorized Audi dealer
or authorized Audi Service Facility check their
funct ion.
@ Tips
For an explanation on conformity with the
FCC regulations in the United States and the
Industry Canada regulations, see

snow and ice. Always read and follow safety
precautions¢.&. .
Winter tires
By using all wheel drive, your vehicle has good
forward motion with standard tires in winter con­
ditions. However, using winter or all season tires
on
all four wheels in the winter is recommended,
because this will improve the
braking effect.
Snow chains
If there are snow chain laws, snow chains must
also be used on vehicles with all wheel drive
¢ page 358, Snow chains.
Replacing tires
For vehicles with all wheel drive, only wheels with
the same rolling circumference should be used.
Avoid using tires with different tread depths
¢ page 348, New tires or wheels.
Offroad vehicle?
Your Audi is not an offroad vehicle -there is not
enough ground clearance. For this reason, avoid
difficult terrain .
A WARNING
-Also, in vehicles with all wheel drive, adapt
your driving style to the current road and
traffic conditions. Do not let the increased
safety provided tempt you into taking risks,
because this increases the risk of an acci­
dent .
- The braking ability of your vehicle is limited
to the traction of the wheels. In this way, it
is not different from a two wheel drive vehi­
cle. Do not be tempted to accelerate to a
high speed when the road is slippery, be­
cause this increases the risk of an accident .
- Note that on wet streets, the front wheels
can "hydroplane" if driving at speeds that
are too high. Unlike front wheel drive
vehicles, the engine does not rev higher sud­
denly when the vehicle begins hydroplaning.
For this reason, adapt your speed to the
road conditions to reduce the risk of an acci­
dent.
Intelligent Technology
Energy management
The starting ability is optimized
T he energy management system manages the
electrical energy distribution and optimizes the
availability of electrical energy for starting the
engtne.
When a vehicle with a conventional energy sys­
tem is not driven for a long time, the vehicle bat­
tery is drained by equipment (for example, the
immobilizer). In certain circumstances , there
could may not be enough energy to start the en­
gine.
Your vehicle is equipped with an intelligent ener­
gy management system for distributing electrici­
ty. This significantly improves the starting ability
and increases the vehicle battery life.
The energy management system Is made up of
battery diagnosis, idling current management,
and dynamic energy management.
Battery diagnosis
The battery diagnosis determines the vehicle bat­
tery charge level. The sensors determine the bat­
tery voltage, the battery current, and the battery
temperature. The current charge level and the
performance of the vehicle battery are deter­
mined based on this.
Idling current management
The idling current management decreases the
energy used while parked. With the engine
switched off, it manages the energy distribution
to the different electrical components . Data from
the battery diagnosis is taken into account for
this.
Depending on the vehicle battery charge level,
electrical equipment is switched off one item af­
ter the other to prevent the vehicle battery from draining and to maintain the starting ability.
Dynamic energy management
While driving, dynamic energy management dis­
tributes the appropriate amount of energy to the
electrical equipment.
It controls the battery
charge level so that the amount of energy is not
