Light Sensor
The light sensor for the DRL is located on top of the
instrument panel. If the sensor is covered, it will prevent
it from sensing light, and the exterior lamps may come
on when they are not needed.
Fog Lamps
The fog lamp controls are located on the turn
signal/multifunction lever.
#(Fog Lamps): The band with this symbol is used to
turn the fog lamps on and off.
The parking lamps must be on for the fog lamps
to work.
To turn the fog lamps on or off, turn the fog lamp band
on the lever up to the dot and release it. The band will
return to its original position.
If the high‐beam headlamps are turned on, the fog
lamps will turn off. The fog lamps will come back on
when the high‐beam headlamps are off.
Some localities have laws that require the headlamps to
be on along with the fog lamps.

Twilight Sentinel®
Twilight Sentinel®can turn the lamps on and off for you.
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, the front turn
signal lamps (DRL) will go off, and the headlamps
and parking lamps will come on. The other lamps
that come on with headlamps will also come on.
.When it is bright enough outside, the headlamps
will go off, and the front turn signal lamps (DRL)
will come on, as long as the exterior lamp switch is
in the off position.
If the vehicle is started in a dark garage, the automatic
headlamp system comes on immediately. Once the
vehicle leaves the garage, it will take about one minute
for the automatic headlamp system to change to DRL if
it is light outside. During that delay, the instrument panel
cluster might not be as bright as usual. Make sure the
instrument panel brightness control is in full bright
position. See Instrument Panel Brightness
on
page 4‑35for more information.
You can idle the vehicle with the lamps off, even when it
is dark outside. First set the parking brake while the
ignition is in OFF/ACCESSORY. Then start the vehicle.
The lamps will stay off until the parking brake is
released.

Entry Lighting
The entry lighting system turns on the reading and
dome lamps and the backlighting to the exterior lamp
control when a door is opened or if you press the
remote keyless entry transmitter unlock button.
If activated by the transmitter, the lighting will remain
active for about 25 seconds. The entry lighting system
uses the light sensor; it must be dark outside in order
for the lamps to turn on. The lamps turn off about
25 seconds after the last door is closed. They will dim
to off if the ignition is on, or immediately deactivate if
the power locks are activated.
Parade Dimming
This feature prohibits dimming of the instrument panel
displays and backlighting during daylight hours when
the key is in the ignition and the headlamps are on.
This feature operates with the light sensor and is fully
automatic. When the light sensor reads darkness
outside and the parking lamps are active, the
instrument panel displays can be adjusted by turning
the instrument panel brightness knob. SeeInstrument
Panel Brightness
on page 4‑35for additional
information.
Reading Lamps
The reading lamps are located on the overhead
console. These lamps come on automatically when any
door is opened.
For manual operation, press the button next to each
lamp to turn it on or off.
If the reading lamps are left on, they automatically shut
off 10 minutes after the ignition has been turned off.
Battery Load Management
The battery load management feature is designed to
monitor the vehicle's electrical load and determine when
the battery is in a heavy discharge condition. During
times of high electrical loading, the engine may idle at a
higher revolutions per minute (rpm) setting than normal
to make sure the battery charges. High electrical loads
may occur when several of the following are on:
headlamps, high beams, fog lamps, rear window
defogger, the climate control fan at high speeds, heated
seats and engine cooling fans.
If the battery continues to discharge, even with the
engine idling at a higher rpm setting, some electrical
loads will automatically be reduced. When this occurs,
the rear window defogger may take slightly longer to
clear the glass and the fan may cut back to a lower

Sensors
The solar sensor located on the instrument panel, near
the windshield, monitors the solar heat.The interior temperature sensor located on the
instrument panel to the right of the steering wheel,
measures the temperature of the air inside the vehicle.
The climate control system uses the information from
these sensors to adjust the temperature, the fan speed
and the air delivery, in order to maintain the selected
temperature. The system may also supply cooler air to
the side of the vehicle facing the sun.
Do not cover the sensors or the automatic climate
control system will not work properly.

the vehicle is in motion.
If the passenger safety belt is buckled, neither the
chime nor the light comes on.
The front passenger safety belt warning light and chime
may turn on if an object is put on the seat such as a
briefcase, handbag, grocery bag, laptop or other
electronic device. To turn off the warning light and or
chime, remove the object from the seat or buckle the
safety belt.
Airbag Readiness Light
The system checks the airbag's electrical system for
possible malfunctions. If the light stays on it indicates
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, see Airbag System on page 2‑57.

High-Speed Operation
{WARNING:
Driving at high speeds, 160 km/h (100 mph) or
higher, puts an additional strain on tires.
Sustained high-speed driving causes excessive
heat build up and can cause sudden tire failure.
You could have a crash and you or others could
be killed. Some high-speed rated tires require
inflation pressure adjustment for high speed
operation. When speed limits and road conditions
are such that a vehicle can be driven at high
speeds, make sure the tires are rated for high
speed operation, in excellent condition, and set to
the correct cold tire inflation pressure for the
vehicle load.
If you will be driving at high speeds, speeds of 100 mph
(160 km/h) or higher, where it is legal, set the cold
inflation pressure to the maximum inflation pressure
shown on the tire sidewall, or 38 psi (265 kPa),
whichever is lower. See the example following. When
you end this high-speed driving, return the tires to the
cold inflation pressure shown on the Tire and Loading
Information label. See Loading the Vehicle
on
page 5‑23. Example:
You will find the maximum load and inflation pressure
molded on the tire's sidewall, in small letters, near the
rim flange. It will read something like this: Maximum
load 690 kg (1521 lbs) 300 kPa (44 psi) Max. Press.
For this example, you would set the inflation pressure
for high‐speed driving at 38 psi (265 kPa).
Tire Pressure Monitor System
The Tire Pressure Monitor System (TPMS) uses radio
and sensor technology to check tire pressure levels.
The TPMS sensors monitor the air pressure in your
vehicle's tires and transmit tire pressure readings to a
receiver located in the vehicle.
Each tire, including the spare (if provided), should be
checked monthly when cold and inflated to the inflation
pressure recommended by the vehicle manufacturer on
the vehicle placard or tire inflation pressure label. (If
your vehicle has tires of a different size than the size
indicated on the vehicle placard or tire inflation pressure
label, you should determine the proper tire inflation
pressure for those tires.)
As an added safety feature, your vehicle has been
equipped with a tire pressure monitoring system
(TPMS) that illuminates a low tire pressure telltale when
one or more of your tires is significantly under‐inflated.
