injury .
• Never let children play in or around the vehicle.
• Never l et passengers ride in the luggage compartment. Vehicl e
occupants must alwa ys be p roperl y res trained in one of the
vehicle 's seat ing posi tions.
(I) Tips
• Air circula tion helps to reduce window fogging. Sta le air escapes
to the outside thro ugh vents in the tr im panel. Be sure to keep these
slots free and ope n.
• Th e tire p ressure m ust co rrespon d to the load . The tire pressure is
show n on the tire p ressu re label. O n USA v ehicles, the tire p ress ure
label is located on the driver's side 8-p illar. On Canada veh icles, the
ti re pressu re lab el is locat ed either on the driver' s sid e B-pillar or
inside the fuel fi lle r flap . The t ire pressure labe l lists the recom ­
mended co ld tire in flati on press ures f or th e ve hicle at its max imum
capacity weight and the tires that were on yo ur vehicle at the time it

I n a co llision, t he laws of physics mean that ev en sma ller items that
are loose i n the vehicle will become heavy missiles t hat can cause
serious injury. Items in the vehicle possess e nergy wh ich vary w ith
vehicle speed and the we ight of the item. Vehicle spee d is t he most
signifi cant factor.
Controls and equip­
ment Safety first Vehicle operation
For example,
in a frontal collis io n at a speed of 30 mph (48 km/ h),
t he forces a ctin g o n a 1 0-lb (4 .5 kg) objec t are ab out 20 times the
normal weight of the item . T his means that the weight of the item
wou ld s udden ly be abo ut 200 lbs . (90 kg). You can imagine the inju­
ries that a 200 lbs . (90 kg) item fly ing freely through the passenger
compartment could cause in a collision like this .
& WARNING
Weak, damaged or improper straps used to secure item s to tie­
downs can fail during hard braking or in a collision and cause
serious personal injury.
• Always use suitable mounting straps and properly secure items
to the tie -downs in the luggage compartment to help prevent
items from shifting or flying forward as dangerous missiles.
• When the rear seat backrest is folded down, always us e suit­
able mounting straps and properly secure items to the tie-downs
in the luggage compartment to help prevent items from flying
forward as dangerous missiles into the passenger compartment .
• Never attach a child safety seat tether strap to a tie-down .•

Trailer towing
"-------------------------------------------------
Trailer load distribution
Be sure the load in the trailer is held securely in pla ce to prevent it
from shifting forward, backward or s ideways.
Never allow a passenger to ride in a trailer => & in "Driving instruc­
tions" on
page 256.
Engine cooling system
Towing a trailer makes the eng ine work harde r. It is important that
the cooling system's performance 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 cold tire
pressure listed under "Full load" on the label located either on the
dr iver's side B-pillar (visible when the door is open) or inside the fuel
filler flap . Inflate trailer tires to trailer and tire manufacturers' spec­
ifications.
Lights
The headl ight settings should be checked w ith the trailer attached
before driving off. Check to make sure both vehicle and trai ler lights
are working properly.
Safety chains
Be sure trailer safety cha ins are properly connected from the trailer
to the hitch on the vehicle. Leave enough s lack in the chains to permit
turning corners. When you install safety chains, make sure they will
not drag on the road when you are driving.
T he chains should cross under the trailer tongue to p revent it from
dropping in case of separation from the hitch.
Driving instruct!ons
Driving with a trailer always requires extra care and
consideration.
To obtain the best possible handling of vehicle and trailer,
please note the following:
- Do not tow a loaded trailer when your car itself is not
loaded.
- Be especially careful when passing other veh icles .
- Observe speed limits.
- Do not drive at the maximum permissible speed.
- Always apply brakes early.
- Monitor the temperature gauge .
Weight distribution
Towing a loaded trailer w ith an empty car results in a highly unstable
distr ibution of weight. If this cannot be avoided, drive at very low
speeds only to avo id the r isk of losing steer ing control.
A "balanced" rig is easier to operate and control. Th is means that the
tow vehicle should be loaded to the extent possible and permissible,
wh ile keeping the trailer as light as possible under the c ircumstances.
Whenever possible, trans fer some cargo to the luggage compart ­
ment of the tow vehicle while observing tongue load requirements
and vehicle loading considerations.
Speed
Th e higher the speed, the more difficult it becomes for the driver to
control the r ig . Do not drive at the maximum permiss ible speed.
Reduce your speed even more if load, weather or wind conditions are
unfavorable -part icularly when go ing downhill.
Reduce vehicle speed
immediately i f the trailer shows the slightest
sign of swaying.
Do not try to stop the swaying by accelerating. _,

-Checking and filling
-------=------=---------------------------------------------------
Closing the engine hood
-Pull the hood down until the pressure from the struts is
reduced.
- Let the hood
drop down and latch in place . Do not try to
push it shut;
it may fail to engage=> &.
& WARNING
A hood that is not completely latched could fly up and block your
view while driving.
• When you close the engine hood, check it to make sure the
safety catch has properly engaged. The hood should be flush with
the surrounding vehicle body parts.
• If you notice while driving that the hood is not secured prop­
erly, stop at once and close it. •
Working in the engine compartment
Be especially careful whenever you work in the engine
compartment.
Whenever you must perform any work in the engine compartment,
for example checking and filling different fluids, there is a risk of
injury, burns and accidents. To prevent personal injury always
observe the following WARNINGS. The engine compartment of any
vehicle is a hazardous area
=> & .
& WARNING
To help avoid injury, before you check anything under the hood :
• Turn off the engine.
• Remove the ignition key.
• Apply the parking brake.
& WARNING (continued)
• Move selector lever of automatic transmission to "P" (Park).
• Always let the engine cool down. Hot components will burn
skin on contact.
• To reduce the risk of being burned, never open the hood if you
see or hear steam or coolant escaping from the engine compart­
ment. Wait until no steam or coolant can be seen or heard before
carefully opening the hood.
• Keep children away from the engine compartment.
• Never spill fluids on hot engine components. They can cause a
fire.
• Never touch the radiator fan. The auxiliary electric fan is
temperature controlled and can switch on suddenly.
• Never open the coolant reservoir cap when the engine is still
warm. The coolant system is pressurized and hot coolant could
spray out.
• Protect your face, hands and arm from steam or hot engine
coolant by placing a thick rag over the cap when you open the
coolant reservoir.
• If work on the fuel system or the electrical system is necessary:
-Always disconnect the battery.
- Never smoke or work near heaters or open flames. Fluids in
the engine compartment could start a fire.
- Keep an approved fire extinguisher immediately available.
• To avoid electrical shock and personal injury while the engine is
running or being started, never touch: -Ignition cables
- Other components of the high voltage electronic ignition system.
• If you must perform a check or repair with the engine running: -First, fully apply the parking brake, move selector lever of
automatic transmission to "P" (Park). ..,

Driv ing with an i nsufficient o il level is likely to cause severe damage
to the engine .
[I) Tips
• The oil pressure warning display 'e:r. is not an ind icator of the oil
level. Do not rely on it . Instead, check the oil level in your engine at
regular intervals, preferably each time you refuel, and always
before going on a long trip.
• If you have the impression your eng ine consumes excessive
amo unts of o il, we re commen d that yo u cons ult an aut ho riz ed Aud i
dealer to have the cause of your concern properly diagnosed . Keep in
m ind th at the accurate measure ment o f oil consumption re quires
great care and may take some time. An author ized Audi dealer has
ins truc tions about how to meas ure o il consumption acc ura tely .•

& WARNING (conti nu ed )
• If the tire i s not flat and you do not ha ve to change a wheel
immediately, drive at reduced speed to the nearest service station
to check the tire pressure and add air as required.
0 Note
Driv ing without valve stem caps can cause damage to the tire valves.
T o preven t this, a lways make sure that fac tory ins talle d valve stem
caps on all wheels are securely mo unted on the valve.
<£> For the sake of the environment
Under inflated t ires will also increase the fuel consumption .•
Tires and vehicle load limits
There are limits to the amo unt of load or weig ht that any vehicle and
any t ire ca n carry. A veh icle th at is overlo ade d w ill n ot handle well and
is more difficult to stop . Overload ing can not on ly lead to loss of
vehicle co ntro l, bu t can also d amage important pa rts of the vehi cle
and can lead to sudden t ire failure, including a b lowo ut and sudden
deflation that can ca use the vehicle to c rash.
Yo ur safety and t hat of your passengers also depends o n mak ing s ure
that load limits are not e xceeded. Vehicle load incl udes eve rybody
and everyth ing in and on the ve hicle. These load limits are tech nically
refer red to as the veh icle's
Gross Vehicle We ight Rating ("GVWR").
T he "GVWR" includes t he weight of the basic vehi cle, all factory
installed accessories, a fu ll tank of fue l, o il, coo la nt and other fluids
plus maxim um load . The maxim um load includes the number of
passenge rs that the vehi cle is intended to car ry ("seating capacity ")
w ith an ass umed we ight of 150 lbs (68 kg) for each pa ssenger at a
designat ed seating position and the tota l w eight of any l uggage in
the vehicle. If you tow a trai le r, the weight o f the t railer hitch and the tongue weight of the
loaded tra ile r must be included as part of the
veh icle lo ad .
T he
Gross Axle Weight Rating ("GAWR ") is the max imum load t hat
can be a pplied at each of the ve hicle's two axles .
Th e Gross Vehicle Weight Rat ing and the Gro ss Axle Weight Ra ting
are listed on the safety compliance s ticker label located on the
dr iver 's s ide B-pillar. Audi h as 4 seat ing pos it ions, 2 in t he fro nt and
2 in the rear for total seating capacity of 4 . Each seating pos it io n has
a seat belt =>
page 19 0, "Safety belts" .
Th e fa ct t hat there is an upper lim it to your veh icle 's Gross Vehicle
We ight Rating means that the total weight of whatever is being
c arrie d in t he ve hicle (incl uding t he weight o f a trail er hi tch and the
tongue weig ht of the loaded tra iler) is limited . The more passengers
in the veh icle or p assenge rs who are he avier than the st anda rd
we ights assumed mean that less we ight can be carried as luggage.
Th e tire pressure labe l o n yo ur Audi a lso lists the max imum combine d
we ight of alt of the o ccupants and l uggage or o ther cargo that the
vehicle ca n carry . For t he locat ion of the label=>

& 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 de signed to carry
will prevent the vehicle from handling properly and increase the
risk of the loss of vehicle control.
• The brakes on a vehicle that has been overloaded may not be
able to stop the vehicle within a safe di stan ce.
• Tires on a vehicle that has been o verloaded can fail suddenly ,
including a blowout and sudden deflation, causing loss of control
and a crash .
• Always make sure that the total load being transported -
