Charging System Warning Light
Red TelltaleLight What It Means
Charging System Warning Light
This light shows the status of the electrical charging system. If the light stays on or comes
on while driving, turn off some of the vehicle’s nonessential electrical devices or increase
engine speed (if at idle). If the charging system light remains on, it means that the vehicle is
experiencing a problem with the charging system. Obtain SERVICE IMMEDIATELY. See an
authorized dealer.
If jump starting is required, refer to “Jump Starting Procedures” in “What To Do In Emer-
gencies.”

•Oil Temperature Warning Light
This telltale indicates engine oil temperature is
high. If the light turns on while driving, stop
the vehicle and shut off the engine as soon as
possible.
• Charging System Light
This light shows the status of the electrical charg-
ing system. If the light stays on or comes on while
driving, turn off some of the vehicle’s non-essential
electrical devices or increase engine speed (if at idle). If
the charging system light remains on, it means that the
vehicle is experiencing a problem with the charging
system. Obtain SERVICE IMMEDIATELY. See an autho-
rized dealer.
If jump starting is required, refer to “Jump Starting
Procedures” in “What To Do In Emergencies”. •
Electronic Throttle Control (ETC) Light
This light informs you of a problem with the
Electronic Throttle Control (ETC) system. The
light will come on when the ignition is first
turned ON and remain on briefly as a bulb
check. If the light does not come on during starting, have
the system checked by an authorized dealer.
If a problem is detected, the light will come on while
the engine is running. Cycle the ignition key when
the vehicle has completely stopped and the transmis-
sion is in the PARK position. The light should turn
off.
If the light remains lit with the engine running, your
vehicle will usually be drivable. However, see an
authorized dealer for service as soon as possible. If
the light is flashing when the engine is running,
immediate service is required. You may experience
reduced performance, an elevated/rough idle or en-
gine stall and your vehicle may require towing.

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.
