Remote Vehicle Start
Your vehicle may have this feature
which allows you to start the
engine from outside the vehicle.
/(Remote Vehicle Start):This
button will be on the RKE transmitter
if you have remote start.
To enable and disable remote start,
see “Remote Start” underDIC
Vehicle Customization on page 4-32.
Vehicles with an automatic climate
control system will default to a
heating or cooling mode depending
on the outside temperature during
a remote start. When the key
is turned to ON/RUN, the climate
control system will turn on at
the setting the vehicle was set to
when the vehicle was last turned off.Laws in some local communities
may restrict the use of remote
starters. For example, some laws
may require a person using remote
start to have the vehicle in view
when doing so. Check local
regulations for any requirements on
remote starting of vehicles.
If your vehicle is low on fuel, do not
use the remote start feature. The
vehicle may run out of fuel.
If your vehicle has the remote start
feature, the RKE transmitter
functions will have an increased
range of operation. However,
the range may be less while the
vehicle is running.
There are other conditions which
can affect the performance of
the transmitter, seeRemote Keyless
Entry (RKE) System on page 2-3
for additional information.Starting the Engine Using
Remote Start
To start the engine using the remote
start feature:
1. PressQon the RKE transmitter.
2. Press and hold
/for about
two seconds. The turn signal
lamps will briey ash to conrm
the vehicle has been started.
The parking lamps will turn
on and remain on as long as the

doors will be locked.
3. After entering the vehicle during
a remote start, insert and turn
the key to ON/RUN to drive
the vehicle.
After a remote start, the engine
will automatically shut off
after 10 minutes unless a time
extension has been done or

the right lane, you could hit a
vehicle on your right. Check
your inside mirror or glance
over your shoulder before
changing lanes.
The passenger side mirror is convex
shaped. A convex mirror’s surface
is curved so more can be seen from
the driver seat. It also makes
things, like other vehicles, look
farther away than they really are.

Warning Lights,
Gages, and Indicators
This section describes the warning
lights and gages on the vehicle.
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
prevent injury.
Warning lights come on when there
may be or is a problem with one
of the vehicle’s functions. Some
warning lights come on briey when
the engine is started to indicate
they are working.Gages can indicate when there may
be or is a problem with one of the
vehicle’s functions. Often gages and
warning lights work together to
indicate a problem with the vehicle.
When one of the warning lights
comes on and stays on while
driving, or when one of the gages
shows there may be a problem,
check the section that explains what
to do. Follow this manual’s advice.
Waiting to do repairs can be
costly and even dangerous.

{CAUTION
Even though the passenger
sensing system is designed to
turn off the right front
passenger’s frontal airbag 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 the rear seat, even if
the airbag is 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
frontal airbag. SeePassenger
Sensing System on page 1-26for
more information, including
important safety information.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 4-13for more on this,
including important safety
information.
Voltmeter Gage
The voltmeter shows the voltage
output of your battery.
It is located in the center of the
instrument panel.
Charging System Light
This light will come on briey when
you turn on the ignition, and the
engine is not running, as a check to
show it is working. Then it should
go out when the engine is started.
If the light comes on and an
Alternator message on the Driver
Information Center (DIC) stays
on, you may have a problem with
the electrical charging system. Have
it checked by your dealer/retailer.

Antilock Brake System
(ABS) Warning Light
For vehicles with the Antilock Brake
System (ABS), this light will come
on briey, as a check, when
you start your vehicle.
If it does not, have your vehicle
serviced so that the light works
properly when it needs to.
If the light and a message in the
DIC stays on longer than a few
seconds after you start your engine,
or comes on and stays on while
you are driving, try resetting
the system. To reset the system:
1. If you are driving, pull over when
it is safe to do so.
2. Place the vehicle in PARK (P).
3. Turn off the ignition.
4. Then restart the engine.If the light remains on after resetting
the system or comes on again
while driving, your vehicle needs
service. If the ABS light is on,
but the regular brake system
warning light is not on, the antilock
brakes are not working properly,
but the regular brakes are still
functioning. Have your vehicle
serviced right away. If both brake
lights are on, you do not have
antilock brakes, and there’s a
problem with your regular brakes as
well. Have your vehicle towed for
service. SeeTowing Your Vehicle
on page 9-84.
The ABS Fault message will remain
until
3(Trip/Fuel) or8(Enter)
are pressed, but the warning
light will remain until the problem is
xed. SeeDIC Warnings and
Messages on page 4-27for more
information.
Engine Coolant
Temperature Gage
This gage shows the engine coolant
temperature. If the gage pointer
moves into the red area, the engine
is too hot. It means that the engine
has overheated. Pull off the road,
stop the vehicle, and turn off the
engine as soon as possible. See
Engine Overheating on page 9-16.

engine is started and provides
information about tire pressures and
the Tire Pressure Monitoring System.
When the Light is Solid
This light will also come on when
one or more of your tires are
signicantly underinated. A CHECK
TIRE PRESSURE DIC message
will accompany the light.
SeeDIC Warnings and Messages
on page 4-27for more information.Stop and check your tires as soon as
it is safe to do so. If underinated,
inate to the proper pressure. See
Tires on page 9-39for more
information.
When the Light Flashes First and
Then is Solid
This indicates that there may be a
problem with the Tire Pressure
Monitor System.
The light ashes for about a minute
and stays on solid for the
remainder of the ignition cycle. This
sequence will repeat with every
ignition cycle. SeeTire Pressure
Monitor System on page 9-49
andTire Pressure Monitor Operation
on page 9-51for more information.
Malfunction
Indicator Lamp
Check Engine Light
A computer system called OBD II
(On-Board Diagnostics-Second
Generation) monitors operation of
the fuel, ignition, and emission
control systems. It makes sure that
emissions are at acceptable
levels for the life of the vehicle,
helping to produce a cleaner
environment.
This light comes on briey, as a
check to show it is working,
when the ignition is turned to
ON/RUN. If the light does not come
on, see your dealer/retailer.
If the light stays on it indicates that
there is an OBD II problem and
service is required.

If you just drove through a deep
puddle of water, your vehicle’s
electrical system might be
wet. The condition is usually
corrected when the electrical
system dries out. A few driving
trips should turn the light off.
If you recently changed brands of
fuel, be sure to fuel your vehicle
with quality fuel. SeeGasoline
Octane on page 8-33. Poor
fuel quality causes the engine
not to run as efficiently as
designed. You might notice this
as stalling after start-up,
stalling when you put the vehicle
into gear, misring, hesitation
on acceleration, or stumbling on
acceleration — these conditions
might go away once the
engine is warmed up.
If you experience one or more of
these conditions, change the
fuel brand you use. It will require
at least one full tank of the
proper fuel to turn the light off.If none of the above have made
the light turn off, your dealer/retailer
can check the vehicle. Your
dealer/retailer has the proper test
equipment and diagnostic tools to
x any mechanical or electrical
problems that might have
developed.
Emissions Inspection and
Maintenance Programs
Some state/provincial and local
governments have or might begin
programs to inspect the emission
control equipment on your vehicle.
Failure to pass this inspection
could prevent getting a vehicle
registration.Here are some things to know to
help your vehicle pass an
inspection:
Your vehicle will not pass this
inspection if the check engine
light is on or not working properly.
Your vehicle will not pass
this inspection if the OBD
(on-board diagnostic) system
determines that critical emission
control systems have not
been completely diagnosed by
the system. The vehicle would be
considered not ready for
inspection. This can happen if
you have recently replaced
the battery or if the battery has
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 you have done this and
your vehicle still does not pass
the inspection for lack of
OBD system readiness, your
dealer/retailer can prepare
the vehicle for inspection.

Oil Pressure Gage
The gage shows the engine oil
pressure.
It is located in the center of the
instrument panel.
{CAUTION
Do not keep driving if the oil
pressure is low. If you do, your
engine can become so hot that
it catches re. You or others

Notice:Lack of proper engine oil
maintenance may damage the
engine. The repairs would not be
covered by the vehicle warranty.
Always follow the maintenance
schedule in this manual for
changing engine oil.
Fuel Gage
The fuel gage shows about how
much fuel you have left, when the
ignition is on.
When the indicator nears empty, the
low fuel warning light will come
on and along with a chime. There is
still a little fuel left, but you should
refuel soon.Here are four things that some
owners ask about. These are normal
and do not indicate a problem
with your fuel gage:
At the service station, the gas
pump shuts off before the
gage reads full.
It takes a little more or less fuel
to ll up than the gage indicated.
The indicator moves a little when
you turn a corner or speed up.
The gage will continue to show
the remaining fuel when the
ignition is turned off.
