tank was half full, but it actually
took a little more or less than
half the tank's capacity to fill
the tank.
.The gauge goes back to empty
when the ignition is turned off.
Engine Coolant
Temperature Gauge
Metric
English
This gauge shows the engine
coolant temperature. Under normal
driving conditions the gauge will
read approximately 100°C (210°F)
or less. If the gauge pointer is near
125°C (260°F), the engine is
too hot.
It means that the engine coolant has
overheated. If the vehicle has been
operating under normal driving
conditions, pull off the road, stop the
vehicle, and turn off the engine as
soon as possible. See
Engine Overheating on
page 10-16 for more information.
Voltmeter Gauge
When the engine is not running, but
the ignition is turned on, this gauge
shows the battery's state of charge
in DC volts.
When the engine is running, this
gauge shows the condition of the
charging system. The vehicle's
charging system regulates voltage
based on the state of charge of the
battery. The voltmeter may fluctuate.

as a system check. Then, after
several more seconds, the status
indicator will light either ON or OFF,
or either the on or off symbol to let
you know the status of the front
outboard passenger frontal airbag.
If the word ON or the on symbol is
lit on the passenger airbag status
indicator, it means that the front
outboard passenger frontal airbag is
allowed to inflate.
If the word OFF or the off symbol is
lit on the passenger airbag status
indicator, it means that the
passenger sensing system has
turned off the front outboard
passenger frontal airbag.
If, after several seconds, both status
indicator lights remain on, or if there
are no lights at all, there may be a
problem with the lights or the
passenger sensing system. See
your dealer for service.{Warning
If the airbag readiness light ever
comes on and stays on, it means
that something may be wrong
with the airbag system. To help
avoid injury to yourself or others,
have the vehicle serviced right
away. SeeAirbag Readiness
Light on page 5-14 for more
information, including important
safety information.
Charging System Light
The charging system light comes on
briefly when the ignition is turned
on, but the engine is not running, as a check to show the light is working.
It should go out when the engine is
started.
If the light stays on, or comes on
while driving, there may be a
problem with the electrical charging
system. Have it checked by your
dealer. Driving while this light is on
could drain the battery.
When this light comes on, the Driver
Information Center (DIC) also
displays the SERVICE BATTERY
CHARGING SYSTEM message.

Malfunction
Indicator Lamp
A computer system called OBD II
(On-Board Diagnostics-Second
Generation) monitors the operation
of the vehicle to ensure emissions

Mexico-7576030) - 2015 - CRC - 8/18/14
5-18 Instruments and Controls
The vehicle may not pass
inspection if:
.The malfunction indicator lamp is
on with the engine running, or if
the light does not come on when
the ignition is turned to ON/RUN
while the engine is off. See your
dealer for assistance in verifying
proper operation of the
malfunction indicator lamp.
.The OBD II (On-Board
Diagnostics) system determines
that critical emission control
systems have not been
completely diagnosed. The
vehicle would be considered not
ready for inspection. This can
happen if the 12-volt battery has
recently been replaced or
run down.
The diagnostic system is designed
to evaluate critical emission control
systems during normal driving. This
can take several days of routine
driving. If this has been done and
the vehicle still does not pass the inspection for lack of OBD II system
readiness, your dealer can prepare
the vehicle for inspection.
Brake System Warning
Light
The vehicle brake system consists
of two hydraulic circuits. If one
circuit is not working, the remaining
circuit can still work to stop the
vehicle. For normal braking
performance, both circuits need to
be working.
If the warning light comes on, there
is a brake problem. Have the brake
system inspected right away.
MetricEnglish
This light should come on briefly
when the ignition key is turned to
ON/RUN. If it does not come on
then, have it fixed so it will be ready
to warn if there is a problem.
This light may also come on due to
low brake fluid. See
Brake Fluid on
page 10-21.
When the ignition is on, the brake
system warning light will also come
on when the parking brake is set.
The light will stay on if the parking
brake does not release fully. If it
stays on after the parking brake is
fully released, it means there is a
brake problem.
If the light comes on while driving,
pull off the road and stop carefully.
Make sure the parking brake is fully
released. The pedal may be harder
to push or, the pedal may go closer
to the floor. It may take longer to
stop. If the light is still on, have the
vehicle towed for service. See
Towing the Vehicle on page 10-72.

Battery Load
Management
The vehicle has Electric Power
Management (EPM) that estimates
the battery's temperature and state
of charge. It then adjusts the voltage
for best performance and extended
life of the battery.
When the battery's state of charge
is low, the voltage is raised slightly
to quickly bring the charge back up.
When the state of charge is high,
the voltage is lowered slightly to
prevent overcharging. If the vehicle
has a voltmeter gauge or a voltage
display on the Driver Information
Center (DIC), you may see the
