CAUTION!
Be sure to mount the spare tire with the
valve stem facing outward. The vehicle
could be damaged if the spare tire is
mounted incorrectly.
9. Lower the vehicle by turning the jack screw counterclockwise, and remove the
jack and wheel blocks. 10. Finish tightening the lug nuts. Push
down on the wrench while at the end of
the handle for increased leverage.
Tighten the lug nuts in a star pattern
until each nut has been tightened twice.
The correct tightness of each lug nut is
130 ft-lbs (176 N·m). If in doubt about
the correct tightness, have them
checked with a torque wrench by your
authorized dealer or service station.
NOTE:
For the SRT model the correct wheel nut
tightness is 110 ft lbs (149 N·m).
11. Lower the jack to the fully closed posi- tion and return it and the tools to the
proper positions in the foam tray.
12. Remove the small center cap and se- curely store the road wheel in the cargo
area. 13. Have the aluminum road wheel and tire
repaired as soon as possible, properly
secure the spare tire with the special
wing nut torqued to 3.7 ft-lbs (5 N·m),
reinstall the jack and tool kit foam tray,
and latch the rear load floor cover.
NOTE:
Do not drive with the spare tire installed for
more than 50 miles (80 km) at a max speed
of 50 mph (80 km/h).

2. Install the remaining lug nuts with thecone shaped end of the nut toward the
wheel. Lightly tighten the lug nuts.
WARNING!
To avoid the risk of forcing the vehicle off
the jack, do not tighten the lug nuts fully
until the vehicle has been lowered. Failure
to follow this warning may result in per-
sonal injury.
3. Lower the vehicle to the ground by turning the jack handle counterclockwise.
4. Finish tightening the lug nuts. Push down on the wrench while at the end of the handle for increased leverage. Tighten the
lug nuts in a star pattern until each nut
has been tightened twice. The correct
tightness of each lug nut is 130 ft-lbs
(176 N·m). If in doubt about the correct
tightness, have them checked with a
torque wrench by your authorized dealer
or service station.
NOTE:
For the SRT model the correct wheel nut
tightness is 110 ft lbs (149 N·m).
5. After 25 miles (40 km) check the lug nut torque with a torque wrench to ensure that
all lug nuts are properly seated against the
wheel.JUMP-STARTING
If your vehicle has a discharged battery it can
be jump-started using a set of jumper cables
and a battery in another vehicle or by using a
portable battery booster pack. Jump-starting
can be dangerous if done improperly so
please follow the procedures in this section
carefully.
WARNING!
Do not attempt jump-starting if the battery
is frozen. It could rupture or explode and
cause personal injury.
CAUTION!
Do not use a portable battery booster pack
or any other booster source with a system
voltage greater than 12 Volts or damage to
the battery, starter motor, alternator or
electrical system may occur.
NOTE:
When using a portable battery booster pack
follow the manufacturer's operating instruc-
tions and precautions.
Preparations For Jump-Starting
The battery in your vehicle is located under
the passenger's front seat. There are remote
locations located under the hood to assist in
jump-starting.

FUEL REQUIREMENTS –
GASOLINE ENGINE
3.6L Engine
This engine is designed to
meet all emissions regula-
tions and provide excel-
lent fuel economy and
performance when using
high-quality unleaded
“Regular” gasoline having
an octane rating of 87 as specified by the
(R+M)/2 method. The use of higher octane
“Premium” gasoline will not provide any ben-
efit over “Regular” gasoline in these engines.
While operating on gasoline with an octane
number of 87, hearing a light knocking sound
from the engine is not a cause for concern.
However, if the engine is heard making a
heavy knocking sound, see your dealer imme-
diately. Use of gasoline with an octane num-
ber lower than 87 can cause engine failure
and may void or not be covered by the New
Vehicle Limited Warranty.
