nuts with the cone-shaped end
toward the wheel. Lightly tighten
the nuts.
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 wheel nut
tightness is 110 ft lbs (150 N·m).
If in doubt about the correct
tightness, have them checked
with a torque wrench by your
authorized dealer or at a service
station.
11. Lower the jack to the fully closed position and return it and the tools to the proper positions in the foam tray.
12. Remove the small center cap and securely store the road wheel in the cargo area.
13. Have the aluminum road wheeland 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),

each lug nut is 110 ft/lbs (150 N·m). If in doubt about the correct
tightness, have them checked with a torque wrench by your authorized
dealer or service station.
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.
CAUTION!
• Do not attempt to raise the vehicle by jacking on locations otherthan those indicated in the Jacking Instructions for this vehicle.
• 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!
• Do not attempt to change a tire on the side of the vehicle close tomoving traffic. Pull far enough off the road to avoid the danger of
being hit when operating the jack or changing the wheel.
• Being under a jacked-up vehicle is dangerous. The vehicle could slip off the jack and fall on you. You could be crushed. Never put any
part of your body under a vehicle that is on a jack. If you need to
get under a raised vehicle, take it to a service center where it can be
raised on a lift.
• Never start or run the engine while the vehicle is on a jack.
• The jack is designed to be used as a tool for changing tires only. The jack should not be used to lift the vehicle for service purposes. The
vehicle should be jacked on a firm level surface only. Avoid ice or
slippery areas.
• Always park on a firm, level surface as far from the edge of the
roadway as possible before raising the vehicle.
• Turn on the Hazard Warning flasher.
• Block the wheel diagonally opposite the wheel to be raised.
• Set the parking brake firmly and set an automatic transmission in PARK.

WARNING!(Continued)
• Do not let anyone sit in the vehicle when it is on a jack.
• Do not get under the vehicle when it is on a jack.
• Only use the jack in the positions indicated and for lifting thisvehicle during a tire change.
• If working on or near a roadway, be extremely careful of motor traffic.
• To assure that spare tires, flat or inflated, are securely stowed, spares must be stowed with the valve stem facing the ground.
• Carefully follow these tire changing warnings to help prevent personal injury or damage to your vehicle:
• Raising the vehicle higher than necessary can make the vehicle less stable. It could slip off the jack and hurt someone near it. Raise the
vehicle only enough to remove the tire.
• 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 personal injury.
• 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.

• Set the parking brake, shift the automatic transmission into PARK
and turn the ignition to LOCK.
• Turn off the heater, radio, and all unnecessary electrical accessories.
• Remove the protective cover over the remote positive (+) battery
post. Pull upward on the cover to
remove it.
• If using another vehicle to jump-start the battery, park the vehicle within the jumper cables reach, set the parking brake and make sure the
ignition is OFF.
Jump-Starting Procedure
• Connect the positive (+)end of the jumper cable to the remote positive
(+) post of the discharged vehicle.
• Connect the opposite end of the positive (+)jumper cable to the positive
(+) post of the booster battery.
• Connect the negative end (-)of the jumper cable to the negative (-)post
of the booster battery.
• Connect the opposite end of the negative (-)jumper cable to the remote
negative (-)post of the vehicle with the discharged battery.
• Start the engine in the vehicle that has the booster battery, let the engine idle a few minutes, and then start the engine in the vehicle with the
discharged battery.
Once the engine is started, remove the jumper cables in the reverse
sequence:
• Disconnect the negative (-)jumper cable from the remote negative (-)
post of the vehicle with the discharged battery.
• Disconnect the negative end (-)of the jumper cable from the negative
(-) post of the booster battery.
• Disconnect the opposite end of the positive (+)jumper cable from the

• If frequent jump-starting is required to start your vehicle you should havethe battery and charging system inspected at your authorized dealer.
CAUTION!
• Do not use a portable battery booster pack or any other boostersource with a system voltage greater than 12 Volts or damage to the
battery, starter motor, alternator or electrical system may occur.
• Failure to follow these procedures could result in damage to the charging system of the booster vehicle or the discharged vehicle.
• Accessories that can be plugged into the vehicle power outlets draw power from the vehicle’s battery, even when not in use (i.e.,
cellular phones, etc.). Eventually, if plugged in long enough, the
vehicle’s battery will discharge sufficiently to degrade battery life
and/or prevent the engine from starting.
WARNING!
• When temperatures are below the freezing point, electrolyte in adischarged battery may freeze. Do not attempt jump-starting
because the battery could rupture or explode and cause personal
injury. Battery temperature must be brought above freezing point
before attempting a jump-start.
• Take care to avoid the radiator cooling fan whenever the hood is raised. It can start anytime the ignition switch is on. You can be
injured by moving fan blades.
• Remove any metal jewelry, such as watch bands or bracelets, that might make an inadvertent electrical contact. You could be severely
injured.
• Batteries contain sulfuric acid that can burn your skin or eyes and generate hydrogen gas which is flammable and explosive. Keep
open flames or sparks away from the battery.
• Do not allow vehicles to touch each other as this could establish a ground connection and personal injury could result.
• Failure to follow this procedure could result in personal injury or property damage due to battery explosion.
• Do not connect the cable to the negative post (-)of the discharged
battery. The resulting electrical spark could cause the battery to
explode and could result in personal injury.
