For vehicles with the Tire Pressure
Monitor System (TPMS), this light
comes on briefly when the engine is
started. It provides information
about tire pressures and the TPMS.
When the Light Is On Steady
This indicates that one or more of
the tires are significantly
underinflated.
Stop as soon as possible, and
inflate the tires to the pressure value
shown on the Tire and Loading
Information label. SeeTire Pressure
0 258.
When the Light Flashes First and
Then Is On Steady
If the light flashes for about a minute
and then stays on, there may be a
problem with the TPMS. If the
problem is not corrected, the light
will come on at every ignition cycle.
See Tire Pressure Monitor
Operation 0260.Engine Oil Pressure Light
Caution
Lack of proper engine oil
maintenance can damage the
engine. Driving with the engine oil
low can also damage the engine.
The repairs would not be covered
by the vehicle warranty. Check
the oil level as soon as possible.
Add oil if required, but if the oil
level is within the operating range
and the oil pressure is still low,
have the vehicle serviced. Always
follow the maintenance schedule
for changing engine oil.
This light should come on briefly as
the engine is started. If it does not
come on, have the vehicle serviced
by your dealer. If the light comes on and stays on, it
means that oil is not flowing through
the engine properly. The vehicle
could be low on oil and might have
some other system problem. See
your dealer.
Low Fuel Warning Light
This light comes on for a few
seconds when the ignition is turned
on as a check to indicate it is
working. If it does not come on,
have it fixed.
This light comes on when the
vehicle is low on fuel.
The low fuel warning light comes on
when there are approximately 6.0 L
(1.7 gal) of fuel remaining in
the tank.

Immobilizer Light
The immobilizer light should come
on briefly as the engine is started.
If it does not come on, have the
vehicle serviced by your dealer.
If the system is working normally,
the indicator light turns off.
If the light stays on and the engine
does not start, there could be a
problem with the immobilizer
system.
See Immobilizer Operation (Key
Access) 046 orImmobilizer
Operation (Keyless Access) 046.
Reduced Engine Power
Light
The reduced engine power light
should come on briefly as the
engine is started. If it does not come
on, have the vehicle serviced by
your dealer.
This light, along with the malfunction
indicator lamp, displays when a
noticeable reduction in the vehicle's
performance occurs.
The vehicle can be driven at a
reduced speed when the reduced
engine power light is on but
acceleration and speed might be
reduced. If this light stays on, see
your dealer as soon as possible for
diagnosis and repair.
High-Beam On Light
This light comes on when the
high-beam headlamps are in use.
See Headlamp High/Low-Beam
Changer 0133.
Front Fog Lamp Light
For vehicles with fog lamps, this
light comes on when the fog lamps
are on.
The light goes out when the fog
lamps are turned off. See Fog
Lamps 0135.

Daytime Running
Lamps (DRL)
DRL can make it easier for others to
see the front of your vehicle during
the day. Fully functional DRL are
required on all vehicles first sold in
Canada.
The DRL system makes the
low-beam headlamps come on at a
reduced brightness when the
following conditions are met:
.
The ignition is on.
. The exterior lamp control is
in AUTO.
. The engine is running.
When the DRL are on, only the
low-beam headlamps, at a reduced
level of brightness, will be on. The
taillamps, sidemarker, instrument
panel, 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
Oand then release. For vehicles

first sold in Canada, the DRL can
only be turned off when the vehicle
is parked.
Automatic Headlamp
System
When it is dark enough outside and
the exterior lamp control is in the
automatic position, the headlamps
come on automatically. SeeExterior
Lamp Controls 0132.
The vehicle has a light sensor on
top of the instrument panel. Make
sure it is not covered, or the
headlamps will be on when they are
not needed. The system may also turn on the
headlamps when driving through a
parking garage or tunnel.
Lights On with Wipers
If the windshield wipers are
activated in daylight with the engine
on, and the exterior lamp control is
in AUTO, the headlamps, parking
lamps, and other exterior lamps
come on. The transition time for the
lamps coming on varies based on
wiper speed. When the wipers are
not operating, these lamps turn off.
Move the exterior lamp control to

Lighting Features
Entry Lighting
Some exterior lamps and interior
lamps turn on briefly at night, or in
areas with limited lighting, when
K
is pressed on the Remote Keyless
Entry (RKE) transmitter. When a
door is opened, the interior lamps
come on if the dome lamp control is
in the Door position. They stay on
for about 20 seconds. When all of
the doors have been closed or the
ignition is turned on, they gradually
fade out.
This feature can be changed. See
“Vehicle Locator Lights”under
Vehicle Personalization 0129.
Exit Lighting
Some exterior lamps and interior
lamps come on at night, or in areas
with limited lighting, when the key is
removed from the ignition. The
exterior lamps and dome lamp
remain on for a set amount of time,
then automatically turn off. If equipped with Keyless Access,
the exterior lamps automatically turn
on when a door is opened after the
ignition is turned off. The dome
lamps also come on after the
ignition is turned off.
See
Ignition Positions (Key Access)
0 181 orIgnition Positions (Keyless
Access) 0183.
The exterior lamps turn off
immediately by turning the exterior
lamps control off.
This feature can be changed. See
Vehicle Personalization 0129.
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
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 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
