23. Electronic Stability Control (ESC) OFF
Indicator Light — If EquippedThis light indicates the Electronic
Stability Control (ESC) is off.
24. Vehicle Security Light This light will flash rapidly for ap-
proximately 15 seconds when the
vehicle theft alarm is arming. The
light will flash at a slower speed
continuously after the alarm is set.
The security light will also come on
for about three seconds when the ignition is first
turned on.
25. Temperature Gauge
The temperature gauge shows engine coolant
temperature. Any reading within the normal
range indicates that the engine cooling system
is operating satisfactorily.
The gauge pointer will likely indicate a higher
temperature when driving in hot weather, up
mountain grades, or when towing a trailer. It should not be allowed to exceed the upper
limits of the normal operating range.
CAUTION!
Driving with a hot engine cooling system could
damage your vehicle. If the temperature
gauge reads “H” pull over and stop the ve-
hicle. Idle the vehicle with the air conditioner
turned off until the pointer drops back into the
normal range. If the pointer remains on the “H”
and you hear continuous chimes, turn the
engine off immediately and call an authorized
dealership for service.
WARNING!
A hot engine cooling system is dangerous.
You or others could be badly burned by steam
or boiling coolant. You may want to call an
authorized dealership for service if your ve-
hicle overheats. If you decide to look under
the hood yourself, see “Maintaining Your Ve-
hicle”. Follow the warnings under the Cooling
System Pressure Cap paragraph.26. Rear Fog Light Indicator
This indicator will illuminate when the
rear fog lights are on.

EVIC Red Telltale LightsThis area will show reconfigurable red telltales.
These telltales include:
•Door Ajar
This light will turn on to indicate
that one or more doors may be
ajar.
• Liftgate Ajar
This light will turn on to indicate
that liftgate may be ajar.
• Liftgate Flipper Glass Ajar
This light will turn on to indicate
that liftgate flipper glass may be
ajar. •
Oil Pressure Warning Light
This light indicates low engine oil pres-
sure. The light should turn on momen-
tarily when the engine is started. If the
light turns on while driving, stop the vehicle and
shut off the engine as soon as possible. A
chime will sound when this light turns on.
Do not operate the vehicle until the cause is
corrected. This light does not show how much
oil is in the engine. The engine oil level must be
checked under the hood.
• Charging System Light
This light shows the status of the elec-
trical charging system. The light
should come on when the ignition
switch is first turned ON and remain on briefly
as a bulb check. If the light stays on or comes
on while driving, turn off some of the vehicle’s
non-essential electrical devices or increase en-
gine speed (if at idle). If the charging system
light remains on, it means that the vehicle is
experiencing a problem with the charging sys-
tem. Obtain SERVICE IMMEDIATELY. See an
authorized dealer. If jump starting is required, refer to “Jump
Starting Procedures” in “What To Do In Emer-
gencies”.
•
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 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 engine stall and your
vehicle may require towing.

•Engine Temperature Warning Light
This light warns of an overheated en-
gine condition. As temperatures rise
and the gauge approaches 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 vehicle. If the tempera-
ture 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 more information.
• Transmission Temperature Light
This light indicates that there is
excessive transmission fluid tem-
perature that might occur with se-
vere usage such as trailer towing.
It may also occur when operating
the vehicle in a high torque con-
verter slip condition, such as 4-wheel-drive
operation (e.g., snow plowing, off- road opera- tion). If this light comes on, stop the vehicle and
run the engine at idle or faster, with the trans-
mission in NEUTRAL until the light goes off.
CAUTION!
Continuous driving with the Transmission
Temperature Indicator illuminated will eventu-
ally cause severe transmission damage or
transmission failure.
WARNING!
If the Transmission Temperature Warning
Light is illuminated and you continue operat-
ing the vehicle, in some circumstances you
could cause the fluid to boil over, come in
contact with hot engine or exhaust compo-
nents and cause a fire.
Engine Oil Change Indicator System
Oil Change Due
Your vehicle is equipped with an engine oil
change indicator system. The “Oil Change
Due” message will flash in the EVIC display for
approximately 10 seconds after a single chime
has sounded, to indicate the next scheduled oil
change interval. The engine oil change indica-
tor system is duty cycle based, which means
the engine oil change interval may fluctuate,
dependent upon your personal driving style.
Unless reset, this message will continue to
display each time you turn the ignition switch to
the ON/RUN position or cycle the ignition to the
ON/RUN position if equipped with Keyless
Enter-N-Go. To turn off the message temporar-
ily, press and release the MENU button. To
reset the oil change indicator system (after
performing the scheduled maintenance) refer
to the following procedure.
Vehicles Equipped With Keyless
Enter-N-Go
1. Without pressing the brake pedal, push the
ENGINE START/STOP button and cycle the
ignition to the ON/RUN position (Do not start
the engine.)
2. Fully depress the accelerator pedal, slowly,
three times within 10 seconds.

Summer Operation
NOTE:
In some cases during high temperature
trailer tow operation the Air Conditioning
system performance may be reduced. This
is to help protect the engine from overheat-
ing during the high load condition.
Your air conditioning system is also equipped
with an automatic recirculation system. Whenthe system senses a heavy load or high heat
conditions, it may use partial Recirculation A/C
mode to provide additional comfort.
Winter Operation
When operating the system during the winter
months, make sure the air intake, located di-
rectly in front of the windshield, is free of ice,
slush, snow, or other obstructions.
Vacation Storage
Anytime you store your vehicle, or keep it out of
service (i.e. vacation) for two weeks or more,
run the air conditioning system at idle for about
five minutes in the fresh air and high blower
setting. This will ensure adequate system lubri-
cation to minimize the possibility of compressor
damage when the system is started again.
