To lessen the risk of
personal injury, do not put
any part of your body under the
vehicle while changing a tire. Do
not start the engine when your
vehicle is on the jack. The jack is
only meant for changing the tire.
•Never use the front or rear
differential as a jacking point.

9. Replace the flat tire with the spare tire, making sure the valve stem is
facing outward. Reinstall the lug nuts, cone side in, until the wheel is
snug against the hub. Do not fully tighten the lug nuts until the wheel
has been lowered.
10. Lower the wheel by turning the jack handle counterclockwise.
11. Remove the jack and fully
tighten the lug nuts in the order
shown.
12. Replace beauty cap, stow the
jack and tools in their respective
locations, making sure they are fully
secured so they do not rattle when
you drive.

2. Slide the wheel under the vehicle
and install the retainer through the
wheel center.
3. Turn the lug wrench clockwise
until the tire is raised to its original
position underneath the vehicle. The
lug wrench will click when the tire
is raised to the stowed position. It
will not allow you to overtighten.
JUMP STARTING YOUR VEHICLE
The gases around the battery can explode if exposed to flames,
sparks, or lit cigarettes. An explosion could result in injury or
vehicle damage.
Batteries contain sulfuric acid which can burn skin, eyes and
clothing, if contacted.
Do not attempt to push-start your vehicle. Automatic
transmissions do not have push-start capability; also, the
catalytic converter may become damaged.
Preparing your vehicle
When the battery is disconnected or a new battery is installed, the
transmission must relearn its shift strategy. As a result, the transmission
may have firm and/or soft shifts. This operation is considered normal and
will not affect function or durability of the transmission. Over time, the
adaptive learning process will fully update transmission operation.
1.Use only a 12–volt supply to start your vehicle.
2. Do not disconnect the battery of the disabled vehicle as this could
damage the vehicle’s electrical system.
3. Park the booster vehicle close to the hood of the disabled vehicle
making sure the two vehiclesdo nottouch. Set the parking brake on
both vehicles and stay clear of the engine cooling fan and other moving
parts.

assisting battery.
4. Make the final connection of the negative (-) cable to the provided
jumpstarting bolt ONLY. Connecting to any other exposed component
may cause an explosion.
Do notuse fuel lines, engine rocker covers or the intake manifold as
groundingpoints.
Do not connect the end of the second cable to the negative (-)
terminal of the battery to be jumped. A spark may cause an
explosion of the gases that surround the battery.
