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 252.
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. _,

0 Note
• Never try to remove dirt, mud or dust if the surface of the vehicle
is dry. Never use a dry cloth or sponge, since this could scratch your
vehicle's paint or windows.
• Never wash your car in bright sunlight. Drops of water act as
magnifying lenses and may damage your paint.
• When you wash your car in the winter: if you rinse your vehicle with
a hose, be careful not to aim the stream of water directly at locks, or
at door or hatch openings -they can freeze shut.
• Never use sponges designed to remove insects, or any kitchen
scouring sponges or similar products. They can damage your paint
finish.
• You should remove debris (such as insects) from the headlight
lenses on a regular basis, for example when refueling your vehicle .
Never use a dry cloth or sponge to clean the headlights. Only use wet
cloths or sponges to prevent scratches .
It is best to use soapy water.
<£> For the sake of the environment
In the interest of the environment, the vehicle should only be washed
in special wash bays. •
Washing your vehicle with a power washer
Cleaning the exterior of your car with a high-pressure
power washer is safe as long as you observe a few simple
rules.
- Before using the power washer, make sure you have read
and understood the WARNINGS=>
& in "General infor­
mation" on
page 256 .
- Always follow the operating instructions for the power
washer. -
Make sure that the jet on the spray hose produces a "fan
shaped spray".
- Do
not hold the spray nozzle too close to soft materials.
When cleaning the vehicle with a power washer always follow the
operating instructions. This applies particularly to the
operating
pressure
and the spraying distance . Maintain a sufficient distance to
soft materials such as rubber hoses and sound/vibration deadening
materials (particularly on the underside of the engine hood). Do not
use a jet which sprays water in a
direct stream or one that has a
rotating jet.
Water temperature should not exceed 140
°F (60 °() .
& WARNING
Never wash tires with a jet that sprays water in a direct stream.
This could cause invisible damage to the tires and weaken them,
even if the spray is from a relatively long distance and for a short
time. Damaged and weakened tires can fail and cause accidents
and personal injury.
0 Note
To avoid damaging your vehicle, always make sure that there is suffi­cient distance between the spray head and soft materials like rubber
hoses , plastic parts and sound-deadening materials. Never aim the
spray head at the same point for a long time. This also applies to
cleaning headlights and painted bumpers. Remember: the closer the
nozzle is to the surface of the material, the greater the stress on the
material. •

Checking and filling Ill
-------------~--
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.
Safety first
& WARNING (continued)
• Move selector lever of automatic transmission to "P" (Park);
put manual transmission in Neutral.
• 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: ..,

Dr iv ing with an insufficient oil level is likely to cause severe damage
to the engine .
[ i ] Tips
• The oil pressure warning display~ is not an indicator 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 engine consumes excessive
amounts of oil, we recommend that you consult an authorized Audi
dealer to have the cause of your concern properly diagnosed. Keep in
m ind that the accurate measurement of o il consumption requires
great care and may take some time. An authorized Audi dealer has
instructions about how to measure oil consumption accurately .•
Checking the engine oil level
Fig. 206 MMI Display:
