JUMP STARTING
WARNING!
•To prevent personal injury or damage to clothing,
do not allow battery fluid to contact eyes, skin or
fabrics. Do not lean over a battery when connecting
jumper cables or allow cable clamps to touch each
other. Keep open flames or sparks away from
battery vent holes. Always wear eye protection
when working with batteries.
• Do not use a booster battery or any other booster
source that has a greater than 12 Volt system, i.e., do
not use a 24 Volt power source.
NOTE: Replacement batteries should both be of equal
size to prevent damage to the vehicle’s charging system.
Your vehicle is equipped with two 12 Volt batteries. If it
becomes necessary to use a booster battery with jumper cables to start a vehicle’s engine because its batteries are
discharged, the following procedure should be used:
Set the parking brake and place an automatic transmis-
sion in PARK (or NEUTRAL for a manual transmission).
Turn off lights, heater and other electrical loads. Observe
charge indicator (if equipped) in both batteries. If the
indicator (if equipped) is light or yellow on either battery,
replace that battery.
CAUTION!
Use the jump start procedure only when the charge
indicator (if equipped) in both batteries is dark in the
center. Do not attempt jump starting when either
battery charge indicator (if equipped) is bright or
yellow. If the charge indicator (if equipped) has a
green dot in the center, failure to start is not due to a
discharged battery and cranking system should be
checked.

2. Connect one end of the other jumper cable to negative(-) post of booster battery. Connect the other end of the
jumper cable to a good ground on the engine block of
the vehicle with the discharged battery. Make sure a
good connection is made, free of dirt and grease.
WARNING!
•Do not connect the cable to the negative post of the
discharge battery. The resulting electrical spark
could cause the battery to explode.
• During cold weather when temperatures are below
freezing point, electrolyte in a discharged battery
may freeze. Do not attempt jump starting because
the battery could rupture or explode. The battery
temperature must be brought up above freezing
point before attempting to jump start. 3. Take care that the clamps from one cable do not
inadvertently touch clamps from the other cable. Do
not lean over the battery when making connection.
The negative connection must provide good electrical
conductivity and current carrying capacity.
4. After the engine is started or if the engine fails to start, cables must be disconnected in the following order:
• Disconnect the negative cable at the engine ground.
• Disconnect the negative cable at the negative post on
booster battery.
• Disconnect the cable from the positive post of both
batteries.

MAINTENANCE PROCEDURES
The pages that follow contain therequiredmaintenance
services determined by the engineers who designed your
vehicle.
Besides those maintenance items specified in the fixed
maintenance schedule, there are other components which
may require servicing or replacement in the future.
CAUTION!
• Failure to properly maintain your vehicle or per-
form repairs and service when necessary could
result in more costly repairs, damage to other
components or negatively impact vehicle perfor-
mance. Immediately have potential malfunctions
examined by an authorized dealership or qualified
repair center.
(Continued)
CAUTION! (Continued)
•Your vehicle has been built with improved fluids
that protect the performance and durability of your
vehicle and also allow extended maintenance inter-
vals. Do not use chemical flushes in these compo-
nents as the chemicals can damage your engine,
transmission, power steering or air conditioning.
Such damage is not covered by the New Vehicle
Limited Warranty. If a flush is needed because of
component malfunction, use only the specified
fluid for the flushing procedure.

Engine Oil
Checking Oil Level
To assure proper lubrication of your vehicle’s engine, the
engine oil must be maintained at the correct level. Check
the oil level at regular intervals. The best time to check
the oil level is before starting the engine after it has been
parked overnight. When checking oil after operating the
engine, first ensure the engine is at full operating tem-
perature, then wait for 30 minutes after engine shutdown
to check the oil.
