adjusted to the load and angle of the vehicle (for example, during
acce leration and brak ing) . This prevents oncoming tra ffic from
experienc ing unnecessa ry glare from your head lights .

another vehicle behind you .•

Starting and stopping the engine
Starting the engine
The engine can only be started with your original Audi
key.
- Set the parking brake.
- Move the selector lever to the neutral position (automatic
transmission: selector lever in P or N)
=> &.
- On vehicles with manual transmission, fully depress the
clutch pedal.
- Turn the ignition key to position
0 => page 119, fig. 136
- do not depress the gas pedal when starting the engine!
- Let go of the key as soon as the engine starts.
A cold engine may at first be loud after it has been started. This is
due to the hydraulic valves building up the oil pressure. This normal
and no need for concern.
If the engine does not start immediately, stop trying after 10
seconds and then try to restart the engine about 30 seconds later.
What to do if the engine does not start
• ~ page 304, "Starting with jumper cables"
• ~ page 306, "Emergency towing with commercial tow truck".
& WARNING
Never start or let the engine run in a confined or enclosed area .
Exhaust fumes from the engine contain carbon monoxide, a color­
less and odorless gas. Carbon monoxide can be fatal if inhaled.
• Never leave the engine idling unattended. An unattended
vehicle with a running engine poses a danger of personal injury or
theft.
0 Note
• Avoid high engine speeds, fast acceleration or heavy engine
loads while the engine is still cold. This could damage the engine.
• The engine cannot be started by pushing or towing the vehicle.
~ For the sake of the environment
To avoid unnecessary engine wear and to reduce exhaust emis­
sions, do not let your vehicle stand and warm up. Be ready to drive
off immediately after starting your vehicle. Maintain moderate
speed until the engine is completely warm. Remember, the engine
performs best at operating temperature.•
Stopping the engine
- Turn the ignition key to position (D => page 119, fig. 136.
& WARNING
• Never turn off the engine until the vehicle has come to a
complete stop.
• The brake booster and servotronic only work when the engine
is running . With the ignition turned off, you have to apply more
force when steering or braking. Since you cannot steer and stop
normally, this can lead to accidents and serious injuries.
• The radiator fan can continue to run for up to 10 minutes even
after you have turned off the engine and removed the ignition key.
The radiator fan can also turn on again if the engine coolant heats
up because of intense sunlight or heat build-up
in the engine
compartment. _,.

& WARNING (continued)
pressure table - risk of accident! Use the highest tire pressure in
the table.
• Do not drive faster than 50 mph (80 km/h) - risk of accident!
• Avoid full-throttle acceleration, sharp braking, and fast
cornering - risk of accident!
• Never drive using more than one space-saving spare wheel -
risk of accident!
• Normal summer or winter tires must not be fitted on the space­
saving spare wheel rim. •
Wheel change
Before changing a wheel
Follow these points for your own and your passenger's
safety when replacing a wheel.
-After you experience a tire failure, pull the car well away
from moving traffic and try to reach level ground before
you stop => & .
- All passengers should leave the car and move to a safe
location (for instance, behind the guardrail)=>& .
- Apply the parking brake firmly=>&.
- Move selector lever to position Pon an automatic trans-
mission; put manual transmission in first gear =>& .
- If you are towing a trailer: unhitch the trailer from your
vehicle.
- Take the tool case and the spare tire=>
page 290 out of
the luggage compartment.
& WARNING
You or your passengers could be injured while changing a wheel if
you do not follow these safety precautions:
• If you have a flat tire, move a safe distance off the road. Turn off
the engine, turn the emergency flasher on and use other warning devices to alert other motorists .
• Make sure that passengers wait in a safe place away from the
vehicle and well away from the roadway and traffic.
• To help prevent the vehicle from moving suddenly and possibly
slipping off the jack, always fully set the parking brake and block
the wheel diagonally opposite the wheel being changed. When one
front wheel is lifted off the ground, placing the Automatic Trans­
mission in "P" (Park), or engaging a gear in a manual transmission
will
not prevent the vehicle from moving .
• Before you change a wheel, be sure the ground is level and firm.
If necessary, use a sturdy board under the jack.
• After installing the spare wheel, make sure that you remount
the flat tire/wheel in its storage area properly and tighten the
knurled retaining screw securely. •
Changing a wheel
When you change a wheel, follow the sequence described
below step-by -step and exactly in that order.
1. Remove the decorative wheel cover*. For more details
see also =>
page 294, "Decorative wheel covers" or
=>
page 295, "Wheels with cap-covered wheel bolts".
2. Loosen the wheel bolts=>
page 295.
3. Locate the proper mounting point for the jack and align
the jack below that point=>
page 296.
4. Lift the car with the jack=> page 296. _,..

Starting with jumper cables
If n ece ssa ry, th e engin e ca n be sta rte d by conne cti ng it to
the battery of another veh ic le .
If the engin e should fai l to start because of a discharge d or weak
b at te ry, the batt ery can be con nected t o the batt er y of
another
ve hic le, using a pair of jumper cables to start the engine.
Jumper cables
Use
only jumper cables of suffici ently large cross section to safely
c arry the st ar ter curre nt. Refer to th e m anuf actu rer's sp ec ificati ons.
Use on ly j umper ca bles with
isolated termi na l clam ps and properly
marked fo r distinct ion :

& WARNING
Batteries contain electricity , acid, and gas. Any of these can cause
very serious or fatal injury. Follow the instructions below for safe
handling of your vehicle 's battery .
• Always shield your eyes and avoid leaning over the battery
whenever possible .
• A discharged battery can already freeze at temperatures just
below 32 °F (0 °C). Before connecting a jumper cable, the frozen
battery must be thawed completely, otherwise it could explode.
• Do not allow battery acid to contact eyes or skin . Flush any
contacted area with water immediately.
• Improper use of a booster battery to start a vehicle may cause
an explosion.
• Vehicle batteries generate e xplosive gases . Keep sparks , flame
and lighted cigarettes away from batteries.
• Do not try to jump start any vehicle with a low acid level in the
battery.
• The voltage of the booster battery must also have a 12-Volt
rating . The capacity (Ahl of the booster battery should not be
lower than that of the discharged battery . Use of batteries of
diffe rent voltage or substantially different "Ah " rating may cause
an explosion and personal injury .
• Never charge a frozen battery. Gas trapped in the ice may cau se
an explosion .
• Never charge or use a battery that has been frozen . The battery
case may have be weakened.
• Use of batteries of different voltage or substantially different
capacity (Ah ) rating may cause an explosion and injury . The
capacity (Ahl of the booster battery should not be lower than that of the discharged battery . ...
