mode, the airow in the rear will be approximately
the same direction, temperature, and fan speed
as the front. Pressing the AUX button again
will turn the rear system and the indicator off.
If the rear controls are adjusted, the system turns
on in a rear independent mode. Airow in the
rear will then be directed according to the settings
of the rear controls. The rear system can be

Warning Lights, Gages,
and Indicators
This part describes the warning lights and
gages on your vehicle. The pictures help to
locate them.
Warning lights and gages can signal that
something is wrong before it becomes serious
enough to cause an expensive repair or
replacement. Paying attention to the warning
lights and gages could also save you or others
from injury.
Warning lights come on when there may be or
is a problem with one of your vehicle’s functions.
As the details show on the next few pages,
some warning lights come on briey when you
start the engine just to let you know they are
working. If you are familiar with this section, you
should not be alarmed when this happens.Gages can indicate when there may be or is a
problem with one of your vehicle’s functions.
Often gages and warning lights work together
to let you know when there is a problem with
your vehicle.
When one of the warning lights comes on and
stays on as you are driving, or when one of
the gages shows there may be a problem, check
the section that tells you what to do about it.
Please follow this manual’s advice. Waiting to
do repairs can be costly and even dangerous.
So please get to know your vehicle’s warning
lights and gages. They can be a big help.
214

Instrument Panel Cluster
The instrument cluster is designed to let you know at a glance how the vehicle is running. You will know
how fast you are going, about how much fuel you have used, and many other things you will need to
know to drive safely and economically.
United States version shown, Canada similar
215

Speedometer and Odometer
The speedometer lets you see your speed in
both miles per hour (mph) and kilometers per
hour (km/h).
The odometer shows how far your vehicle has
been driven, in either miles or kilometers.
Your vehicle has a tamper-resistant odometer.
If your vehicle needs a new odometer installed,
the new one will be set to the mileage total of the
old odometer. If this is not possible, it will be
set at zero and a label must be put on the driver’s
door to show the old mileage reading when the
new odometer was installed. If the mileage
is unknown, the label should then indicate
“previous mileage unknown”.
Tachometer
The tachometer displays the engine speed in
revolutions per minute (rpm).
Safety Belt Reminder Light
When the key is turned to ON or START, a chime
will come on for several seconds to remind
people to fasten their safety belts, unless the
driver’s safety belt is already buckled.
The safety belt light
will also come on
and stay on for
several seconds,
then it will ash for
several more.
This chime and light is repeated if the driver
remains unbuckled and the vehicle is in motion.
If the driver’s belt is already buckled, neither
the chime nor the light will come on.
216

Passenger Safety Belt
Reminder Light
Several seconds after the key is turned to ON or
START, a chime will sound for several seconds
to remind the front passenger to buckle their
safety belt. This would only occur if the passenger
airbag is enabled. SeePassenger Sensing
System on page 85for more information. The
passenger safety belt light will also come on
and stay on for several seconds, then it will ash
for several more.
This chime and light
are repeated if the
passenger remains
unbuckled and
the vehicle is
in motion.
If the passenger’s safety belt is buckled,
neither the chime nor the light will come on.
Airbag Readiness Light
There is an airbag readiness light on the
instrument panel cluster, which shows the
airbag symbol. The system checks the airbag’s
electrical system for malfunctions. The light
tells you if there is an electrical problem.
The system check includes the airbag sensor,
the pretensioners, the airbag modules, the wiring
and the crash sensing and diagnostic module.
For more information on the airbag system,
seeAirbag System on page 76.
This light will come on
when you start your
vehicle, and it will ash
for a few seconds.
Then the light should
go out. This means
the system is ready.
217

If the airbag readiness light stays on after you
start the vehicle or comes on when you are driving,
your airbag system may not work properly.
Have your vehicle serviced right away.
{CAUTION:
If the airbag readiness light stays on after
you start your vehicle, it means the airbag
system may not be working properly. The
airbags in your vehicle may not inate in
a crash, or they could even inate without
a crash. To help avoid injury to yourself
or others, have your vehicle serviced right
away if the airbag readiness light stays
on after you start your vehicle.
The airbag readiness light should ash for a
few seconds when you turn the ignition key to ON.
If the light does not come on then, have it xed
so it will be ready to warn you if there is a problem.
Passenger Airbag Status Indicator
Your vehicle has the passenger sensing system.
Your instrument panel has a passenger airbag
status indicator.
When you start the vehicle, the passenger airbag
status indicator will light ON and OFF, or the
symbol for on and off, for several seconds as a
system check. If you use remote start to start your
vehicle from a distance, if your vehicle has this
feature, you may not see the 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
right front passenger’s frontal and seat-mounted
side impact airbags.
United StatesCanada
218

If the word ON or the on symbol is lit on the
passenger airbag status indicator, it means that
the right front passenger’s frontal airbag and
seat-mounted side impact airbag are enabled
(may inate).
{CAUTION:
If the on indicator comes on when you have
a rear-facing child restraint installed in the
right front passenger’s seat, it means that
the passenger sensing system has not
turned off the passenger’s frontal airbag
and seat-mounted side impact airbag
(if equipped). A child in a rear-facing child
restraint can be seriously injured or killed if
the right front passenger’s airbag inates.
This is because the back of the rear-facing
child restraint would be very close to the
inating airbag. Do not use a rear-facing
child restraint in the right front passenger’s
seat if the airbag is turned on.
{CAUTION:
Even though the passenger sensing
system is designed to turn off the right
front passenger’s frontal airbag and
seat-mounted side impact airbag
(if equipped) if the system detects a
rear-facing child restraint, no system is
fail-safe, and no one can guarantee that
an airbag will not deploy under some
unusual circumstance, even though it is
turned off. We recommend that rear-facing
child restraints be secured in a rear seat,
even if the airbag is or airbags are off.
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 right front passenger’s frontal airbag and
seat-mounted side impact airbag. SeePassenger
Sensing System on page 85for more on this,
including important safety information.
219

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/retailer for service.
{CAUTION:
If the airbag readiness light in the
instrument panel cluster ever comes on
and stays on, it means that something may
be wrong with the airbag system. If this
ever happens, have the vehicle serviced
promptly, because an adult-size person
sitting in the right front passenger’s
seat may not have the protection of the
airbag(s). SeeAirbag Readiness Light
on page 217for more on this, including
important safety information.
Charging System Light
The charging system
light will come on briey
when you turn on the
ignition, but the engine is
not running, as a check
to show you it is working.
It should go out once the engine is running. If it
stays on, or comes on while you are driving, you
may have a problem with the charging system.
It could indicate that you have problems with a
generator drive belt, or another electrical problem.
Have it checked right away. Driving while this light
is on could drain your battery.
When this light comes on, the Driver Information
Center (DIC) will also display the SERVICE
BATTERY CHARGING SYSTEM message. See
DIC Warnings and Messages on page 244for more
information.
If you must drive a short distance with the light on,
be certain to turn off all your accessories, such as
the radio and air conditioner.
