Cruise control
General information
The cruise control system allows you to maintain a
constant speed.
The cruise control system allows you to maintain and constant
driving speed when driving faster than 18 mph (30 km/h) -to the
extent this is possible with the given engine power and braking
characteristics. This allow you to take your foot off the "gas" and
rest it, especially on long trips .
The indicator light CRUISE (USA)/
•l'l (CDNl in the instrument cluster
illuminates when the system is on .
& WARNING
• To help keep the vehicle under control, do not use the cruise
control system when driving on winding or slippery roads (as
caused by heavy rain or loose gravel on the road surface), or in
heavy or varying traffic.
• Only use the cruise control when traffic, road and weather
co nd itions allow you to drive at a steady speed.
[ i] Tips
The cruise control cannot maintain a constant speed when driving
downhill. The vehicle will accelerate under its own weight. Down­
shift to a lower gear or use the brakes to slow down .•
Storing a speed
You must set and then store a vehicle speed using the
cruise control.

- Release the lever to store the new speed.

& WARNING (continued)
• If you must install a rearward-facing child safety seat on the
front passenger seat because of exceptional circumstances and
the PASSENGER AIR BAG OFF light does not appear and stay on ,
immediately install the rear -facing child safety seat in a rear
seating posit ion and have the airbag system inspected by your
Audi dealer .
• A tight tether or other strap on a rearward-facing child restraint
attached to the front passenger seat can put too much pressure
on the weight-sensing mat in the seat and register more weight
than is actually on the seat. The heavier weight registered can make the system work as though an adult were on the seat and
deploy the Advanced Airbag when it must be suppressed causing
serious or even fatal injury to the child.
• If , in exceptional circumstances , you must install a forward ­
facing child restraint on the front passenger seat , always move the
seat into its rearmost position in the seat 's fore and aft adjust­
ment range , as far away from the airbag as possible. The backrest
must be adjusted to an upright position . Make sure that the
PASSENGER AIR BAG OFF light comes on and stays on all the time
whenever the ignition is switched on .
& WARNING
• If the PASSENGER AIR BAG OFF light does not go out when an
adult is sitting on the front passenger seat after taking the steps
described above , make sure the adult is properly seated and
restrained at one of the rear seating positions .
• Have the airbag system inspected by your Audi dealer before
transporting anyone on the front passenger seat .

Improper care , servicing and repair pro cedures can increase the
risk of personal injury and death by preventing an airbag from
deploying when needed or deploying an airbag unexpectedly :
• Never cover, obstruct, or change the steering wheel horn pad
or airbag cover or the instrument panel or modify them in any way.
• Never attach any objects such as cup holders or telephone
mountings to the surfaces covering the airbag units .
• For cleaning the horn pad or instrument panel , use only a soft ,
dry cloth or one moistened with plain water . Solvents or cleaners
could damage the airbag cover or change the stiffness or strength
of the material so that the airbag cannot deploy and protect prop ­
erly .
• Never repair , adjust , or change any parts of the airbag system.

The correct tire pressure for the spore wheel is located on a label
either on the driver's side B-pillar or inside the fuel filler flap.
Because technical changes may be made to vehicle equipment
during the model year, always compare the tire size designation on
the tire pressure label on your vehicle with the tires on your vehicle.
Make sure that the tire size information on the vehicle label is the
same as the size of the tires on the vehicle. This is especially impor­
tant if the vehicle belongs to someone else or you bought the
vehicle with different rims/tires or you bought the vehicle as a previ­
ously owned vehicle .
Remember, your safety and that of your passengers also depends
on making sure that load limits are not exceeded. Vehicle load
includes everybody and everything in and on the vehicle. These load
limits are technically referred to as the vehicle's Gross Vehicle
Weight Rating ("GVWR"l. The Gross Axle Weight Rating ("GAWR"l is
the maximum load that can be applied at each of the vehicle's two
axles. The Gross Vehicle Weight Rating and the Gross Axle Weight
Rating are listed on the safety compliance sticker label located
either on the driver's side B-pillar or on the inside of the fuel filler
flap. The tire pressure label on your Audi lists the maximum
combined weight of all of the occupants and luggage or other cargo
that the vehicle can carry. For the location of the tire pressure label
=> page 297, fig. 217.
& WARNING
Overloading a vehicle can cause loss of vehicle control, a crash or
other accident, serious personal injury, and even death.
• Carrying more weight than your vehicle was designed to carry
will prevent the vehicle from handling properly and increase the risk of a loss of vehicle control.
• The brakes on a vehicle that has been overloaded may not be
able to stop the vehicle within a safe distance.
• Tires on a vehicle that has been overloaded can fail suddenly
causing loss of control and a crash.
& WARNING (continued)
• Always make sure that the total load being transported -
including the weight of a trailer hitch and the tongue weight of a
loaded trailer -does not make the vehicle heavier than the
vehicle's Gross Vehicle Weight Rating.
& WARNING
• Incorrect tire pressures and/or underinflation can lead to a
serious or fatal accident.
• Incorrect tire pressures and/or underinflation cause increased
tire wear and can affect the handling of the vehicle.
• Incorrect tire pressures and/or underinflation can also lead to
sudden tire failure, including a blowout and sudden deflation,
causing loss of vehicle control. •
Checking tire pressure
The correct tire pressure for the tires originally installed
on your vehicle is listed on the tire pressure label located
either on driver's side B-pillar or inside the fuel filler flap.
The recommended tire pressures are on the tire pressure label and
in the
table=> page 297, "Cold tire inflation pressure". This means
that the pressure must be checked and adjusted when the tire has
not been driven for more than a couple of miles (kilometers) at low
speeds during the previous three hours. Air in the tires expands
when the tire heats up as a result of internal friction as it flexes in
use. The tire pressure is higher when the tire has warmed up than
when it is "cold."
It is the inflation pressure in a "cold" tire that counts. Therefore, you
should never let air out of a warm tire to match "Cold tire inflation
pressure"
recommendations=> page 297. The tires would then be
underinflated and could fail suddenly. .,._

& W ARNING (continued )
• The driver is respon sible for the correct tire pre ssure s for all
tire s on the vehicle. The applicable pressure values are located on
a st icker on the driver 's side B-pillar or on the inside of the fuel
filler flap.
• Only when all tire s on the vehicle are filled to the correct pres­
sure , the tire pressure monitoring system * can work correctly .
• The use of incorrect tire pressure values can lead to accidents
or other damage. Therefore it is essential that the driver observe
the specified tire pressure values for the tires and the correct pres­
sures for the function of the tire pressure monitoring system*.
• Always inflate tires to the recommended and correct tire pres ­
sure before driving off.
• Driving with underinflated tires bend more , letting them get
too hot resulting in tread separation , sudden tire failure and loss
of control.
• Ex cessive speed and /overloading can cause heat build -up ,
sudden tire failure and loss of control .
• If the tire pressure is too low or too high, the tires will wear
prematurely and the vehicle will not handle well.
• If the tire is not flat and you do not have to change a wheel
immediately, drive at reduced speed to the nearest service station
to che ck the tire pressure and add air as required .
0 Note
Driving without valve stem caps can cause damage to the tire
valves. To preve nt th is, a lways make s ure th at f acto ry installed va lve
stem caps on al l whee ls are securely mounted on the va lve .
~ For the sake of the environment
Underinflated tires will a lso increase the fuel consumpt io n. •
Tires and vehicle load limits
There are limits to the amount of load or weight t hat any vehic le and
any tire can carry . A ve hicle that i s ove rloa ded will not handle well
and is more d iff icu lt to stop . Overload ing can not only lead to loss
o f vehi cle control, but can also damag e impor tan t p arts o f the
