7. Mount the spare tire.

Mounting Spare Tire

NOTE:
For vehicles so equipped, do not attempt to install
a
center cap or wheel cover on the compact spare
Ú page 236.
8. I nstall the lug nuts with the cone shaped end
of
the lug nut toward the wheel. Lightly tighten
the lug nuts. 9. Low
er the vehicle to the ground by turning the
j
ack handle counterclockwise.
10. Finish tightening the wheel bolts. Push down on
the wrench while at the end of the handle
for increased leverage. Tighten the wheel bolts
in a star pattern until each wheel bolt has been
tightened twice. If in doubt about the correct
tightness, have them checked with a torque
wrench by an authorized dealer or at a service
station
Ú page 245.
11. S tow the jack, tools and flat tire. Make sure the
b
ase of the jack faces the front of the vehicle
before tightening down the fastener.
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.
NOTE:
When using a portable battery booster pack, follow
t h
e manufacturer's operating instructions and
precautions.
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.
WARNING!
To avoid the risk of forcing the vehicle off the
jack, do not tighten the wheel nuts fully until the
vehicle has been lowered. Failure to follow this
warning may result in serious injury.
WARNING!
A loose tire or jack thrown forward in a collision
or hard stop could endanger the occupants of
the vehicle. Always stow the jack parts and the
spare tire in the places provided. Have the
deflated (flat) tire repaired or replaced
immediately.
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.

VEHICLE IDENTIFICATION NUMBER (VIN)
The VIN is on the left front corner of the instrument
panel. The VIN is visible from outside of the vehicle
through the windshield.

Windshield VIN Location

NOTE:
It is illegal to remove or alter the VIN.
BRAKE SYSTEM
Your vehicle is equipped with dual hydraulic brake
systems. If either of the two hydraulic systems
loses normal capability, the remaining system will
still function. There will be some loss of overall
braking effectiveness. This may be evident by increased pedal travel during application, greater
pedal force required to slow or stop, and potential
activation of the Brake Warning Light.
In the event power assist is lost for any reason (for
ex

ample, repeated brake applications with the
engine OFF), the brakes will still function. The
effort required to brake the vehicle will be much
greater than that required with the power system
operating.
WHEEL AND TIRE TORQUE SPECIFICATIONS
Proper lug nut/bolt torque is very important to
ensure that the wheel is properly mounted to the
vehicle. Any time a wheel has been removed and
reinstalled on the vehicle, the lug nuts/bolts
should be torqued using a properly calibrated
torque wrench using a high quality six sided (hex)
deep wall socket.
TORQUE SPECIFICATIONS
**Use only authorized dealer recommended lug nuts/
bolts and clean or remove any dirt or oil before tightening.
Inspect the wheel mounting surface prior to
mounting the tire and remove any corrosion or
loose particles.

Wheel Mounting Surface

Tighten the lug nuts/bolts in a star pattern until
ea
ch nut/bolt has been tightened twice. Ensure
that the socket is fully engaged on the lug nut/bolt
(do not insert it halfway).
NOTE:
If in doubt about the correct tightness, have them
c h
ecked with a torque wrench by an authorized
dealer or service station.
After 25 miles (40 km), check the lug nut/bolt
t or

que to be sure that all the lug nuts/bolts are
properly seated against the wheel.

FUEL REQUIREMENTS
While operating on gasoline with the required
octane number, 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 a dealer immediately. Use of
gasoline with a lower than recommended octane
number can cause engine failure and may void the
New Vehicle Limited Warranty. Poor quality gasoline can cause problems such as
h
a

rd starting, stalling, and hesitations. If you
experience these symptoms, try another brand of
gasoline before considering service for the vehicle.
3.6L ENGINE
This engine is designed to meet all
emissions regulations and provide
e x
cellent 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
pr

emium gasoline will not provide any benefit over
regular gasoline in these engines.
5.7L ENGINE
Do not use E-85 flex fuel or ethanol blends greater
than 15% in this engine.
This engine is designed to meet all
emissions regulations and provide
sa

tisfactory fuel economy and
performance when using high-quality
unleaded gasoline having an octane range of 87 to
89 as specified by the (R+M)/2 method. The use of
89

octane plus gasoline is recommended for
optimum performance and fuel economy.
REFORMULATED GASOLINE
Many areas of the country require the use of
cleaner burning gasoline referred to as “reformulated gasoline”. Reformulated gasoline
contains oxygenates and are specifically blended
to reduce vehicle emissions and improve air
quality.
The use of reformulated gasoline is recommended.
P
r

operly blended reformulated gasoline will
provide improved performance and durability of
engine and fuel system components.
MATERIALS ADDED TO FUEL
Besides using unleaded gasoline with the proper
octane rating, gasolines that contain detergents,
corrosion and stability additives are
recommended. Using gasolines that have these
additives will help improve fuel economy, reduce
emissions, and maintain vehicle performance.
Designated TOP TIER Detergent Gasoline
contains a higher level of detergents to
fu

rther aide in minimizing engine and
fuel system deposits. When available,
the usage of TOP TIER Detergent Gasoline is
recommended. Visit www.toptiergas.com for a list
of TOP TIER Detergent Gasoline Retailers.
Indiscriminate use of fuel system cleaning agents
s h

ould be avoided. Many of these materials
intended for gum and varnish removal may contain
active solvents or similar ingredients. These can
harm fuel system gasket and diaphragm materials.
WARNING!
To avoid the risk of forcing the vehicle off the
jack, do not tighten the lug nuts/bolts fully until
the vehicle has been lowered. Failure to follow
this warning may result in personal injury.
