Beca use techn ica l changes may be made to vehicle equipment during
the model year, always compare the tire size designation o n the tire
pressure labe l on yo ur vehi cle w it h the tires on your ve hicle. Make
sure that the tire size information on the ve hicle labe l is the same as
t he s ize of the tires on the vehicle. This is especia lly im portant if the
vehicle belongs to someone e lse or you boug ht the vehicle w it h
different r ims/ tires or you bo ugh t the vehicle as a prev iously owne d
veh icle .
Remember, your safety and that of your passengers also depends on
ma king sure that load limits are not exceeded. Vehicle load includes
everybody and everything in an d on the vehicle . These load limits are
t echnically refer red to as the veh icle's G ross Ve hicle Weig ht Ra ting
("GVWR"). The Gross Axle Weight Rating ("GAWR") is the max imum
load that ca n be applied at ea ch of the vehi cle's two axles. The G ross
Vehicle Weight Rating and the Gross Ax le Weight Rating are listed on
t he safety compliance sticke r label lo cated ei ther on the d river 's side
B-pil lar or o n the inside of the fuel filler flap. T he tire pressure label
on yo ur A udi lists the maximum comb ined weight o f all of the occu -pa
nts and luggage or other ca rgo that the ve hicle can carry . For the

& WARNING
Overloading a vehicle can cause loss of vehicle control, a crash or
other accident, serious personal injury, and even death.
• Carry ing more weight than your vehicle was designed to carry
will prevent the vehicle from handling prope rly and increase the
ri sk of a lo ss of vehicle control.
• The brakes on a vehicle that has been overloaded may not be
able to stop the vehicl e within a safe distance.
• Tires on a vehicle that ha s been overloaded can fail suddenly
causing lo ss of control and a crash .
• Always make sure that the total load being transported -
i ncluding the weight of a trailer hitch and the tongue weight of a
loaded trailer -does not make the vehicle heavier than the
vehicle 's Gro ss Vehicle Weight Rating .

It is becoming increasingly more and more difficult to replace veh icle
light bu lbs since in many cases, other parts of the car must first be
removed before you are able to get to the bulb. This applies especially
to the light bulbs in the front of your car which you can only reach
through the engine compartment.
•
Sheet metal and bu lb holders can have sharp edges that can cause
serious cuts, and parts must be correctly taken apart and then prop- .,

32 °F (0 °C ). Before connecting a jumper cable, you must thaw the
frozen battery completely, otherwise it could explode.
• Do not allow battery acid to contact eyes or sk in . Flush any
contacted area with water immedi ately .
• Improper use of a booste r battery to start a vehicle may cause
an explosion .
• Vehicle batteries generate e xplosive gases. Keep sparks, flame
and lighted cigarettes away from batterie s.
• 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 (Ah) of the booster battery should not be
lower than that of the discharged battery . Use of batteries of
different voltage or substantially different "Ah " rating may cau se
an e xplosion and personal injury.
• Never charge a frozen battery . Gas trapped in the ice may cause
an explosion.
• Never charge or use a battery that has been frozen. The battery
c ase may have be weakened .
• Use of batteries of different voltage or substantially different
