WARNING!(Continued)
• To assure that spare tires, flat or inflated, are securely stowed,
spares must be stowed with the valve stem facing the ground.
• Raising the vehicle higher than necessary can make the vehicle less
stable and cause a collision. 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.
• A loose tire or jack, thrown forward in a collision or hard stop, could
endanger the occupants of the vehicle. Always stow thejack parts
and the spare tire in the places provided.
• To avoid the risk of forcing the vehicle off the jack, do not tighten
the lug nuts fully until the vehicle is lowered to the ground.
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 the
manufacturer’s operating instructions
and precautions.
Preparations for Jump-Start
• The battery in your vehicle is located in the right rear of the engine
compartment.
• 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.
• 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 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 a good
engine ground (exposed metal part of the discharged vehicle’s engine)
away from the battery and the fuel injection system.
• 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 engine ground 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
positive (+) post of the booster battery.
• Disconnect the positive (+) end of the jumper cable from the positive (+)
post of the discharged vehicle.
• If frequent jump-starting is required to start your vehicle you should have
the battery and charging system inspected at your authorized dealer.
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.
• 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 a
discharged 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.
