A light sensor on top of the
instrument panel makes the DRL
work, so be sure it is not covered.
The DRL system makes the
low-beam headlamps come on at a
reduced brightness or for vehicles
with High Intensity Discharge (HID)
headlamps, the DRL lights will come
on when the following conditions
are met:
.The ignition is in the ON/
RUN mode.
.The exterior lamp control is
in AUTO.
.The engine is running.
.The vehicle is not in P (Park).
When the DRL are on, only the
low-beam headlamps, at a reduced
level of brightness, will be on. The
high-beam headlamps, taillamps,
sidemarker, instrument panel lamps,
and other lamps will not be on.
The headlamps automatically
change from DRL to the regular
headlamps depending on the darkness of the surroundings. The
other lamps that come on with the
headlamps will also come on.
When it is bright enough outside,
the headlamps go off and the DRL
come on.
To turn the DRL lamps off or on
again, turn the exterior lamp control
to the off position and then release.
For vehicles first sold in Canada,
the DRL cannot be turned off.
This vehicle may have a DRL
disabling function. When the DRL
are on and a turn signal is activated,
the DRL on that side will be off until
the turn signal goes off.
Twilight Sentinel
This feature automatically turns the
lamps on and off. A light sensor on
top of the instrument panel makes
the Twilight Sentinel
®work, so be
sure it is not covered.
With Twilight Sentinel the following
will happen:
.When it is dark enough outside,
and the exterior lamp control is
in the AUTO position, the
Daytime Running Lamps (DRL)
go off, and the headlamps and
parking lamps come on. The
other lamps that come on with
the headlamps also come on.

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
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 of the
power needed for very high
electrical loads.
A high electrical load occurs when
several of the following are on, such
as: 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 DIC message might
be displayed and it is recommended
that the driver reduce the electrical
loads as much as possible. See
Battery Voltage and Charging
Messages on page 5-28.
Battery Power Protection
The battery saver feature is
designed to protect the vehicle's
battery.
If some interior lamps are left on
and the ignition is turned off, the
battery rundown protection system
automatically turns the lamp off after
some time.
Exterior Lighting Battery
Saver
The exterior lamps turn off about
10 minutes after the ignition is
turned off, if the parking lamps or
headlamps have been manually left
on. This protects against draining
the battery. To restart the 10-minute
timer, turn the exterior lamp control
to the off position and then back to
the parking lamp or headlamp
position.
To keep the lamps on for more than
10 minutes, the ignition must be in
the ACC/ACCESSORY or ON/RUN
position.

High Intensity Discharge
(HID) Lighting
{Warning
The high intensity discharge
lighting system operates at a very
high voltage. If you try to service
any of the system components,
you could be seriously injured.
Have your dealer or a qualified
technician service them.
After an HID headlamp bulb has
been replaced, the beam might be a
slightly different shade than it was
originally. This is normal.

Electrical System
Electrical System
Overload
The vehicle has fuses and circuit
breakers to protect against an
electrical system overload.
When the current electrical load is
too heavy, the circuit breaker opens
and closes, protecting the circuit
until the current load returns to
normal or the problem is fixed. This
greatly reduces the chance of circuit
overload and fire caused by
electrical problems.
Fuses and circuit breakers protect
power devices in the vehicle.
Replace a bad fuse with a new one
of the identical size and rating.
If there is a problem on the road and
a fuse needs to be replaced, the
same amperage fuse can be
borrowed. Choose some feature of
the vehicle that is not needed to use
and replace it as soon as possible.
