Hazard Warning Flashers
The hazard warning ashers warn others.
They also let police know you have a problem.
Your front and rear turn signal lamps will
ash on and off.
The hazard warning
asher button is
located on top of the
steering column.
The hazard warning ashers work no matter what
ignition position the key is in, and even if the
key is not in the ignition.Press the button to make the front and rear turn
signal lamps ash on and off. Press the button
again to turn the ashers off.
When the hazard warning ashers are on, your
turn signals will not work.
Other Warning Devices
If you carry reective triangles, you can set
them up at the side of the road about
300 feet (100 m) behind your vehicle.
Horn
To sound the horn, press the horn symbols on
the steering wheel pad.

Electric Power 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 put the charge
back in. When the state of charge is high, the
voltage is lowered slightly to prevent overcharging.
If the vehicle has a voltmeter gage or voltage
display on the Driver Information Center (DIC),
you may see the voltage move up or down.
This is normal. If there is a problem, an alert will
be displayed.
The battery can be discharged at idle if the
electrical loads are very high. This is true for all
vehicles. This is because the generator (alternator)
may not be spinning fast enough at idle to
produce all the power that is needed for very
high electrical loads.A high electrical load occurs when several of the
following loads are on: headlamps, high beams,
fog lamps, rear window defogger, climate
control fan at high speed, heated seats, engine
cooling fans, trailer loads, and loads plugged
into accessory power outlets.
EPM works to prevent excessive discharge
of the battery. It does this by balancing the
generator’s output and the vehicle’s electrical
needs. It can increase engine idle speed to
generate more power, whenever needed.
It can temporarily reduce the power demands
of some accessories.
Normally, these actions occur in steps or levels,
without being noticeable. In rare cases at the
highest levels of corrective action, this action
may be noticeable to the driver. If so, a Driver
Information Center (DIC) message might be
displayed, such as Battery Saver Active or
Service Battery Charging System. If this message
is displayed, it is recommended that the driver
reduce the electrical loads as much as possible.
SeeDIC Warnings and Messages on page 224.

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.
Your vehicle may also have a Driver Information
Center (DIC) that works along with the warning
lights and gages. SeeDriver Information
Center (DIC) on page 220for more information.

Voltmeter Gage
When your engine is
not running, but the
ignition is in RUN,
this gage displays
the battery voltage
in DC volts.
When the engine is running, the gage shows the
condition of the charging system. The gage may
transition from a higher to lower or a lower to higher
reading. This is normal. Readings between the
low and high warning zones indicate the normal
operating range. The voltmeter gage may also read
lower when in fuel economy mode. This is normal.Readings in the low warning zone may occur
when a large number of electrical accessories
are operating in the vehicle and the engine is
left idling for an extended period. This condition
is normal since the charging system is not able
to provide full power at engine idle. As engine
speeds are increased, this condition should correct
itself as higher engine speeds allow the charging
system to create maximum power.
You can only drive for a short time with the
reading in either warning zone. If you must drive,
turn off all unnecessary accessories.
Readings in either warning zone indicate a
possible problem in the electrical system.
Have the vehicle serviced as soon as possible.

Brake System Warning Light
When the ignition is on, the brake system warning
light will come on when you set your parking
brake. The light will stay on if your parking brake
does not release fully. If it stays on after your
parking brake is fully released, it means your
vehicle has a brake problem. A chime may
also sound when the light comes on.
Your vehicle’s hydraulic brake system is divided
into two parts. If one part is not working, the
other part can still work and stop you. For good
braking, though, you need both parts working well.
If the warning light comes on, there could be
a brake problem. Have your brake system
inspected right away.This light should come on briey when you
turn the ignition key to RUN. If it does not
come on then, have it xed so it will be ready
to warn you if there is a problem.

If the light comes on while you are driving, pull
off the road and stop carefully. You may notice
that the pedal is harder to push or the pedal
may go closer to the oor. It may take longer
to stop. If the light is still on, have the vehicle
towed for service. SeeTowing Your Vehicle
on page 362.
{CAUTION:
Your brake system may not be working
properly if the brake system warning light
is on. Driving with the brake system
warning light on can lead to an accident.
If the light is still on after you have pulled
off the road and stopped carefully, have
the vehicle towed for service.
Anti-Lock Brake System
Warning Light
With the Anti-Lock
Brake System (ABS),
this light will come
on when you start
your engine and may
stay on for several
seconds, that is normal.
A chime may also sound when the light comes on.
If the light stays on, or comes on when you are
driving, your vehicle needs service. If the regular
brake system warning light is not on, you still
have brakes, but you do not have anti-lock brakes.
If the regular brake system warning light is also
on, you do not have anti-lock brakes and there
is a problem with your regular brakes. See
Brake System Warning Light on page 208earlier
in this section.
The ABS warning light should come on briey
when you turn the ignition key to RUN. If the
light does not come on then, have it xed so
it will be ready to warn you if there is a problem.

StabiliTrak®Service Light
This light will come
on briey when the
engine is started.
This light will come on if a problem is detected
in the StabiliTrak
®system.
For more information seeStabiliTrak
®System
on page 313.
StabiliTrak®Indicator Light
This warning light
should come on
briey when the
engine is started.
During most driving conditions, this light will not
come on. If the StabiliTrak
®System is actively
controlling the stability and/or traction of the
vehicle, this light will ash. This is normal.
This light will come on if any portion of the system
has been manually turned off or a problem is
detected in the system.
If your vehicle has a Driver Information Center,
a message will appear also, seeDIC Warnings
and Messages on page 224andStabiliTrak
®
System on page 313for more information.
