2009 AUDI S4 CABRIOLET tow

Steps for Determining Correct Load Limit
1. Locate the statement "THE COMBINED
WEIGHT OF OCCUPANTS AND CARGO SHOULD NEVER EXCEED XXX KG OR XXX
LBS"on your vehicle's placard (tire infla­
tion pressure label)=>
page 271, fig. 207.
2. Determine the combined weight of the
driver and passengers that will be riding
in your vehicle.
3. Subtract the combined weight of the
driver and passengers from
"XXX" kilo­
grams or
"XXX" pounds shown on the
sticker=>
page 271, fig. 207.
4. The resulting figure equals the available
amount of cargo and luggage load
capacity. For example, if the
"XXX"
amount equals 1400 lbs. and there will
be five
150 lbs. passengers in your
vehicle, the amount of available cargo
and luggage load capacity is
650 lbs.
( 1400- 750 (5 x 150) = 650 I bs.)
Tires and wheels 1111111
5. Determine the combined weight of
luggage and cargo being loaded on the
vehicle. That weight may not safely exceed the available cargo and luggage
load capacity calculated in Step
4.
6. If your vehicle will be towing a trailer,
load from your trailer will be transferred
to your vehicle. Consult this manual to
determine how this reduces the avail­
able cargo and luggage load capacity of
your vehicle.
- Check the tire sidewall (=>
page 279,
fig. 211) to determine the designated
load rating for a specific tire. •

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. _,..

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

& 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 . ...
