•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 au-
thorized dealer.
Refer to “Jump Starting Procedures” in “What To Do In
Emergencies” if jump starting is required. •
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 shift lever is
placed 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 autho-
rized 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 engine stall and your vehicle may
require towing.

•Engine Temperature Warning Light
This light warns of an overheated engine condi-
tion. As temperatures rise and the gauge ap-
proaches H,this indicator will illuminate and a single
chime will sound after reaching a set threshold. Further
overheating will cause the temperature gauge to pass H,
a continuous chime will occur until the engine is allowed
to cool.
If the light turns on while driving, safely pull over and
stop the vehicle. If the A/C system is on, turn it off. Also,
shift the transmission into NEUTRAL and idle the ve-
hicle. If the temperature reading does not return to
normal, turn the engine off immediately and call for
service. Refer to “If Your Engine Overheats” in “What To
Do In Emergencies” for further information.
NOTE: When the transmission is shifted to Neutral,
activate the parking brake to prevent the vehicle from
