all of the following conditions are met.
The exterior lamp control is in AUTO.
The headlamps have not already been activated by
automatic lighting.

if equipped.
Headlamps on Reminder
If you turn the ignition to LOCK while leaving the lamps
on, you will hear a warning chime once the driver’s
door is opened.
Daytime Running Lamps (DRL)/
Automatic Headlamp System
Daytime Running Lamps (DRL) can make it easier for
others to see the front of your vehicle during the
day. DRL can be helpful in many different driving
conditions, but they can be especially helpful in the short
periods after dawn and before sunset. Fully functional
Daytime Running Lamps are required on all vehicles rst
sold in Canada.
A light sensor on top of the instrument panel makes the
DRL work, so be sure it is not covered. The DRL
system will make front parking and turn signal lamps
come on in daylight when the following conditions
are met:
The ignition is on.
The exterior lamps control is off.
When the DRL are on, only your front turn signal lamps
will be on. Your instrument panel will not be lit up.
3-16

When it is dark enough outside, the exterior lamps will
come on automatically. When it is bright enough
outside, the exterior lamps will turn off and the DRL will
turn on. Of course, you may still turn on the headlamps
any time you need to.
If you start your vehicle in a dark garage, the automatic
headlamp system will come on immediately. Once
you leave the garage, it will take approximately
30 seconds for the automatic headlamp system to
change to DRL if it is light outside. During that delay,
your instrument panel cluster may not be as bright
as usual. Make sure your instrument panel brightness
control is in the full bright position. SeeInstrument Panel
Brightness on page 3-17.
To idle your vehicle with the DRL and automatic
headlamps off, toggle the exterior lamp control to off
after starting the vehicle.
As with any vehicle, you should turn on the regular
headlamp system when you need it.Instrument Panel Brightness
The knob to adjust the
instrument panel
brightness is located in the
center of the interior
lamp controls.

Ultrasonic Rear Parking Assist
(URPA)
If your vehicle is equipped with the Ultrasonic Rear
Parking Assist (URPA) system, it is designed to help you
park, while the vehicle is in REVERSE (R). It operates
only at very low speeds, less than 3 mph (5 km/h).
URPA can help make parking easier and to help you
avoid colliding with objects such as parked vehicles. The
URPA system can detect objects up to 5 feet (1.5 m)
behind the vehicle, and tell you how close these objects
are from your rear bumper.
Your vehicle’s URPA operates when the shift lever is
moved into REVERSE (R) and the vehicle speed is less
than 3 mph (5 km/h). Four ultrasonic sensors located
at the rear bumper are used to detect the distance to the
object. The URPA display is located inside the vehicle,
near the rear window. It has three color-coded lights
used to provide distance and system information to the
driver.
{CAUTION:
Even with the Ultrasonic Rear Park Assist
system, the driver must check carefully before
backing up. The system does not operate above
typical backing speeds of 3 mph (5 km/h) while
parking. And, the system does not detect
objects that are more than 5 feet (1.5 meters)
behind the vehicle.
So, unless you check carefully behind you
before and when you back up, you could strike
children, pedestrians, bicyclists or pets behind
you, and they could be injured or killed.
Whether or not you are using rear park assist,
always check carefully behind your vehicle
before you back up and then watch closely as
you do.
