Driving
General information
Breaking in
A new vehicle must be broken in, and the break­ in distance should be 1,000 miles (1,500 km).
For the first 600 miles (1,000 km), do not drive
at speeds that are more than 2/3 of the maxi­
mum permitted RPM, avoid full acceleration and
do not tow a trailer. You may gradually start in­
creasing 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
higher 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 .
Avoid damaging the vehicle
When you are driving on poor roads, or over
curbs, steep ramps , etc., make certain that low­
lying parts such as spoilers and exhaust system
parts do not bottom out and get damaged.
This is especially true for vehicles with low-slung
chassis (sports chassis)* and fully loaded
vehicles.
Driving through water on roads
Note the following to reduce the risk of vehicle
damage when driving through water, for example
on flooded roads:
- The water must not be any higher than the bot­
tom of the vehicle body.
- Do not drive faster than walking speed.
58
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.
([) Note
Vehicle components such as the engine,
transmission, suspension or electrical system
can be severely damaged by driving through
water.
(D 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 safely.
-Avoid driving through salt water, because
this can cause corrosion.
Economical and environmentally-friendly
driving
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
engaged, for example, when you notice that the
next traffic light is red. This produces an engine
braking effect, which helps to protect the brakes
and tires and reduces the emissions and fuel

Fig. 79 Perm itted ball pos itio n of th e t rail er hitch
Trailer towing weights
With a
factory-installed or an aftermarket trailer
hitch, the maximum permissible trailer weight is
2,200 lbs (1,000 kg) . The maximum permissible
unbraked trailer weight is 1,650 lbs (750 kg) .
These specifications apply when driving on roads having an incline of less than 12%.
Permissible tongue load
For best vehicle handling under these changed
conditions, adjust the trailer load so that the
tongue load is at the maximum allowable or
slightly lower. You can get an approximation of
the tongue load with a bathroom scale or you can
measure the load at a trucking company or
weighing station.
With a
factory-installed or an aftermarket trailer
hitch, the maximum permissible load on the ball
hitch may not exceed 220 lbs (100 kg) .
It is rec­
ommended to use the maximum permissible
load.
Trailer load distribution Be sure the load in the trailer is held securely in
place to prevent it from shifting forward, back­
ward or sideways.
Never allow a passenger to ride in a trailer ¢.&.
in Driving instructions on page 76 .
Ball mount
The trailer hitch may only be used with suitable ball mount and ball¢
fig. 79. Installation of the
hitch ball must be carried out in accordance with
the manufacturer's instructions .
Trailer towing
Engine cooling system
Towing a trailer makes the engine work harder. It
is important that the cooling system's perform­
ance is up to the additional load. Make sure that
the cooling system has enough fluid.
Tire pressure
When towing a trailer, inflate the tires of your
vehicle to the tire pressure listed under "Full
load" on the tire pressure label
¢page 181. In­
flate trailer 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 trailer to the hitch on the vehicle .
Leave enough slack in the chains to permit turn­
ing corners. When you install safety chains, make
sure they will not drag on the road when you are
driving.
The chains should cross under the trailer tongue
to prevent it from dropping in case of separation
from the hitch.
· Driving instructions
Driving with a trailer always requires extra care
ond consideration.
Weight distribution
Towing a loaded trailer with an empty car results
in a highly unstable distribution of weight. If this
cannot be avoided, drive at very low speeds only
to avoid the risk of losing steering control.
A "balanced " rig is easier to operate and control.
This means that the tow vehicle should be loaded
to the extent possible and permissible, while
keeping the trailer as light as possible under the
circumstances. Whenever possible, transfer
some cargo to the luggage compartment of the
tow vehicle while observing tongue load require-
ments and vehicle loading considerations. .,.

All wheel drive (quattro)
A ppl ies to: ve hicles wit h all wheel drive
In oil wheel drive, oil four wheels ore powered.
General info rmation
I n all wheel drive, t he driving power is divided be­
tween all four wheels . This happens automatical­
ly depending on your driving behavior as well as
the current road conditions. Also see
¢ page 92.
The a ll wheel d rive concept is designed for h igh
engine powe r. Your vehicle is exceptionally pow­
erful and has excellent driving characteristics both under norma l driving conditions and on
snow and ice. Always read and fo llow safety pre­
cautions ¢.&. .
Winter t ires
By using all wheel drive, yo ur vehicle has good
forward motion with standard tires in w inter con­
ditions. However, we recommend using winter or
all season tires on
all four whee ls in the winter,
because this will improve the
broking effect.
Snow cha in s
If there are snow chain laws, snow chains must
a lso be used on vehicles with a ll wheel drive
¢ page 186, Snow chains.
Replacing t ires
F or vehicles w ith all wheel dr ive, only wheels w ith
the same ro lling circumference shou ld be used .
Avoid using tires with different tread depths
¢ page 178, New tires or wheels .
A WARNING
-Also, in vehicles with a ll wheel drive, adapt
your dr iv ing style to the current road and
traff ic conditions. Do not let the increased
safety provided tempt you into tak ing risks,
because th is increases the r is k of an acci­
dent.
- The braking ability of your veh icle is limited
to the tract ion of the wheels . In this way, it
is not diffe rent from a two whee l dr ive vehi­
cl e. Do not be tempted to accelerate to a
high speed when the road is slippe ry, be­
cause this increases the risk of an accident .
Intellig ent Technology
- Note that on wet streets, the front wheels
can "hydrop lane" if dr iv ing at speeds that
are too high . Un like front wheel drive
veh icles, the engine does not rev higher sud­
denly when the vehicle begins hydroplan ing .
For this reason, adapt yo ur speed to the
road conditions to red uce the risk of an acci­
dent.
Energy management
The starting ability is optimized
The energy management system manages the
electrical energy distribution and optimizes the
availability of electrical energy for starting the
engine.
When a vehicle with a conventiona l energy sys­
tem is not driven for a long time , the vehicle bat­
tery is drained by equipment (for example, the
immobilizer). In certa in circumstances, there
could may not be enough energy to start the en ­
gine.
Yo ur vehicle is equipped with an intel ligent ener ­
gy management system for distributing electrici­
ty . Th is sign ificantly improves the start ing ability
and increases the vehicle battery life .
The energy management system Is made up of
battery diagnosis , idling current manag em en t,
and dynamic energy manag ement .
Battery diagn osis
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 a re 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 dis tribution
to the d ifferent e lectr ica l components. Data from
the battery d iagnosis is taken into account for
t hi s.

Driving safety
-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 eyelets and
suitable straps.
A WARNING
Heavy loads will influence the way your vehi­
cle handles. To help reduce the risk of a loss
of control leading to serious personal injury:
- Always keep in mind 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 100.
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 fitting 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 Panoramic sliding sunroof*,
- Open all air outlets in the instrument pan-
el,
- Switch off the air recirculation,
- Set the fresh air fan to the highest speed .
106
A WARNING
,--
Always make sure that the doors, all win­
dows, the Panoramic sliding sunroof* and the
rear lid are securely closed and locked to re­
duce the risk of injury when the vehicle is not
being used .
-After closing the rear lid, always make sure
that it is properly closed and locked.
- Never leave your vehicle unattended espe­
cially with the rear lid left open. A child
could crawl into the vehicle through the lug­
gage compartment and close the rear lid be­
coming trapped and unable to get out. Be­
ing trapped in a vehicle can lead to serious
personal injury.
- Never let children play in or around the vehi­
cle.
- Never let passengers ride in the luggage
compartment. Vehicle occupants must al­
ways be properly restrained in one of the ve­
hicle's seating positions.
(D Tips
- Air circulation helps to reduce window fog­
ging. Stale air escapes to the outside
through vents in the trim panel. Be sure to keep these slots free and open .
- The tire pressure must correspond to the
load. The tire pressure is shown on the tire
pressure label. The tire pressure label is lo­
cated on the driver's side B-pillar . The tire
pressure label lists the recommended cold
tire inflation pressures for the vehicle at its
maximum capacity weight and the tires that
were on your vehicle at the time it was man­
ufactured. For recommended tire pressures
for normal load conditions, please see chap­
ter
¢ page 181.
Tie-downs
The luggage compartment is equipped with four
tie-downs to secure luggage and other items.
Use the tie-downs to secure your cargo properly

Wheels and Tires
General information
.,.Check your tires regularly for
damage (punctures, cuts, cracks
and bulges). Remove foreign ob­
jects from the tire tread.
.,. If driving over curbs or similar
obstacles, drive slowly and ap­
proach the curb at an angle.
.,.Have faulty tires or rims re­
placed immediately.
"'Protect your tires from oil,
grease and fuel.
.,.M ark tires before removing
them so that the same running
direction can be maintained if
they are reinstalled.
"'Lay tires flat when storing and
store them in a cool, dry location
with as little exposure to light as
possible.
(D Note
-Please note that summer and
winter tires are designed for
the conditions that are typical in those seasons. Audi recom­
mends using winter tires dur­
ing the winter months. Low
temperatures significantly de­ crease the elasticity of summ­
er tires, which affects traction
Wheels
and braking ability. If summer
tires are used in very cold
temperatures, cracks can form
on the tread bars, resulting in
permanent tire damage that
can cause loud driving noise
and unbalanced tires.
-Burnished, polished or
chromed rims must not be
used in winter driving condi­
tions. The surface of the rims
does not have sufficient corro­
sion protection for this and
could be permanently dam­ aged by road salt or similar
substances.
