2. Pull the jumping vehicle (with the good bat-
tery) into a position so the jumper cables can reach
the dead battery and that vehicle’s engine. Make sure
that the vehicles do NOT touch.
3. Place the transmissions/transaxles of both ve-
hicles in Neutral (MT) or P (AT), as applicable, then
firmly set their parking brakes.
*ff necessary for safety reasons, the hazard
lights on both vehicles may be operated
throughout the entire procedure without sig-
nificantiy increasing the diff icuity of jumping
the dead battery.
4. Turn all lights and accessories OFF on both
vehicles. Make sure the ignition switches on both ve-
hicles are turned to the OFF position.
5. Cover the battery cell caps with a rag, but do
not cover the terminals.
6. Make sure the terminals on both batteries are
clean and free of corrosion or proper electrical con-
nection will be impeded. If necessary, clean the bat-
tery terminals before proceeding.
7. Identify the positive (+) and negative (-) termi-
nals on both batteries.
8. Connect the first jumper cable to the positive
(t) terminal of the dead battery, then connect the
other end of that cable to the positive (t) terminal of
the booster (good) battery.
9. Connect one end of the other jumper cable to
the negative (−) terminal on the booster bat-
tery and the final cable clamp to an engine bolt head,
alternator bracket or other solid, metallic point on the
engine with the dead battery. Try to pick a ground on
the engine that is positioned away from the battery in
order to minimize the possibility of the 2 clamps
touching should one loosen during the procedure.
DO NOT connect this clamp to the negative (-) termi-
nal of the bad battery. cable on the donor battery. Disconnect the positive
cable from the donor battery and finally, disconnect
the positive cable from the formerly dead battery. Be
careful when disconnecting the cables from the posi-
tive terminals not to allow the alligator clips to touch
any metal on either vehicle or a short and sparks will
occur.

Your vehicle was supplied with a jack for emer-
gency road repairs. This jack is fine for changing a
flat tire or other short term procedures not requiring
you to go beneath the vehicle. If it is used in an emergency situation, carefully follow the instructions
provided either with the jack or in your owners man-
ual. Do not attempt to use the jack on any portions of
the vehicle other than specified by the vehicle manu-
facturer. Always block the diagonally opposite wheel
when using a jack.
A more convenient way of jacking is the use of a
garage or floor jack. You may use the floor jack to
raise the front of the vehicle by placing it under the
front subframe. The rear of the vehicle is most easily
raised by using the lift points on the drip rail. All
models are equipped with lift points located on the
mid- crossmember in the front and a bracket located
on the floorpan underneath the trunk.
Never place the jack under the radiator, engine or
transaxle components. Severe and expensive damage
will result when the jack is raised. Additionally, never
jack under the floorpan or
bodywork; the
metal will
Whenever you plan to work under the vehicle, you
must support it on jackstands or ramps. Never use
cinder blocks or stacks of wood to support the vehi-
cle, even if you’re only going to be under it for a few
minutes. Never crawl under the vehicle when it is
supported only by the tire-changing jack or other
*Always position a block of wood or small
rubber pad on top of the jack or jackstand to
protect the lifting point’s finish when lifting
or supporting the vehicle.
Small hydraulic, screw, or scissors jacks are satis-
factory for raising the vehicle. Drive-on trestles or
Be very careful to keep the jumper cables
away from moving parts (cooling fan, belts,
etc.) on both engines.
10. Check to make sure that the cables are routed
away from any moving parts, then start the donor ve-
hicle’s engine. Run the engine at moderate speed for
several minutes to allow the dead battery a chance to
receive some initial charge.
11. With the donor vehicle’s engine still running
slightly above idle, try to start the vehicle with the
dead battery. Crank the engine for no more than 10 &stands also on the
Fig. 225 The most practical place to place
front of the vehicle is
seconds at a time and let the starter cool for at least
20 seconds between tries. If the vehicle does not start
in 3 tries, it is likely thatsomething else is also
wrong or that the battery needs additional time to
charge.
12. Once the vehicle is started, allow it to run at
idle for a few seconds to make sure that it is operat-
ing properly.
13. Turn ON the headlights, heater blower and, if
equipped, the rear defroster of both vehicles in order
to reduce the severity of voltage spikes and subse-
quent risk of damage to the vehicles’ electrical sys-
tems when the cables are disconnected. This step is
especially important to any vehicle equipped with
computer control modules.
14. Carefully disconnect the cables in the’reverse
order of connection. Start with the negative cable that
is attached to the engine ground, then the negative Fig. 226 Place the jackstands also
