_& WARNING
Improper use of the veh icle jack can cause se­
rious pe rsonal injuries.
- Never use the screw driver hex head to
tighten wheel bolts, since the bo lts cannot
attain the necessa ry tightening torque if yo u
use the hex head, potentially causing an ac ­
cide nt.
- The factory-supplied jack is intended only
for your vehicle mode l. Under no circum­
stances should it be used to lift heavy
vehicles or other loads; you risk injuring
yourse lf.
- Never start the engine when the vehicle is
raised , which cou ld cause an accident .
- Support the vehicle securely with appropri ­
ate stands if work is to be performed under­ neath the vehicle; otherwise, there is a po­
tential risk for injury.
- Never use the jack supplied with your Aud i
on another vehicle, particularly on a heavier
one. The jack is only su itab le for use on the
vehicle it came with .

Loosening the wheel bolts
Fig. 199 Changing a tire: loosen the wheel bolts
• Slide the wheel wrench (from the vehicle tool
kit) all the way onto the wheel bolt.
• Turn the wheel bolt approximately one turn to
the left -arrow-. To reach the required torque,
hold the end of the wheel wrench. If the wheel
bolt will not loosen, press carefully on the
whee l wrench with your foot. Hold onto the ve­
hicle securely while during this and make sure
your stance is stable .
A WARNING
To reduce the risk of an accident, only loosen
the wheel bolts gently (one turn) before rais­
ing the vehicle with the veh icle jack*.

Fig. 201 Sill: positio ning the vehicle jack
• Place the veh icle jack* (vehicle tool kit) on a
firm s urface. Use a flat, stable support if neces­
sary. On a slippery surface such as tile, you
should use a non-slip pad (such as a rubber
mat)
c:> & .
• Find the marking on the sill that is closest to
the tire that will be changed
c:> fig. 200. Behind
the marking, there is a lifting point on the side
sill for the vehicle jack*.
• Tu rn the vehicle jack* located u nder the mount­
ing point on the sill to raise the jack until its
arm
(D c:> fig. 201 i s located under the desig­
nated mou nting point .
• Align the vehicle jack* so the arm @engages in
the designated mounting point in the side sill
and the base @lies flat on the ground. The
base @must be direct ly under the mounting
point @.
• Continue raising the vehicle jack* until the
wheel lifts off the ground slightly.
A WARNING
- Make sure the vehicle jack* is stable. There
is a risk of injury when the ground is slick or
soft, because the vehicle jack* could slide or
sink.
- Only raise your vehicle w ith the vehicle jack*
provided by the factory. If you use a vehicle
jack designed for another vehicle, your vehi­
cle can slide and cause injury .
- Pos ition the vehicle jack* only at the desig­
nated mounting points on the side sill and
align the jack . Otherwise, the vehicle jack*
co uld slip and cause an injury if it does not
have sufficient hold on the vehicle.
- To reduce the risk of an accident, never start
the engine when the vehicle is raised.
