This indicator light turns on in the
instrument cluster when the high-beam
headlamps are on.
Flash-to-Pass
To flash the high beams, pull the turn signal
lever all the way toward you. Then
release it.
Daytime Running Lamps (DRL)
Daytime Running Lamps 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.
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
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 off or on again, turn the
exterior lamp control to the off position and
then release. For vehicles first sold in
Canada, the DRL can only be turned off
when the vehicle is parked.
Automatic Headlamp System
If equipped, the headlamps come on
automatically when it is dark enough
outside and the exterior lamp control is in
the automatic position. See
Exterior Lamp
Controls 096.
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

158 Driving and Operating
Rear Cross Traffic Alert (RCTA)
On vehicles with RCTA, a triangle with an
arrow may display on the infotainment
display to warn of traffic coming from either
direction. This system detects objects
coming from up to 20 m (65 ft) from the left
or right side, behind the vehicle. When an
object is detected, three beeps sound from
the left or right side, depending on the
direction of the detected vehicle.
The Park Assist and RCTA symbols appear
and may cover an object when viewing the
infotainment display when an object is
detected by the RPA or RCTA system. To
turn the symbols on or off, seeVehicle
Personalization 093.
RCTA can be turned on or off through
vehicle personalization. See “Collision
Detection Systems” underVehicle
Personalization 093.
Park Assist
If equipped, Rear Park Assist (RPA) system, it
assists you with parking and avoiding
objects while in R (Reverse). RPA operates at
speeds less than 8 km/h (5 mph), and the
sensors on the rear bumper detect objects
up to 1.5 m (5 ft) behind the vehicle, and at least 30 cm (12 in) off the ground. The
distance objects can be detected may be
less during warmer or humid weather.
{Warning
The Park Assist system does not detect
children, pedestrians, bicyclists, animals,
or objects below the bumper or that are
too close or too far from the vehicle. It is
not available at speeds greater than
8 km/h (5 mph). To prevent injury, death,
or vehicle damage, even with Park Assist,
always check the area around the vehicle
and check all mirrors before backing.
How the System Works
RPA comes on automatically when the shift
lever is moved into R (Reverse).
An obstacle is indicated by audible beeps.
The interval between the beeps becomes
shorter as the vehicle gets closer to the
obstacle. When the distance is less than
30 cm (12 in) the beeping is a continuous
tone for five seconds.
Turning the System On and Off
The RPA system can be turned on and off
using the infotainment system controls. See
Vehicle Personalization
093.
When the System Does Not Seem to
Work Properly
This light may come on for the following
reasons:
.The sensors are not clean. Keep the
vehicle's rear bumper free of mud, dirt,
snow, ice, and slush. For cleaning
instructions, see Exterior Care0226.
.The Park Assist sensors are covered by
frost or ice. Frost or ice can form around
and behind the sensors and may not
always be seen; this can occur after
washing the vehicle in cold weather. The
light may not clear until the frost or ice
has melted.

.An object was hanging out of the liftgate
during the last drive cycle. Once the
object is removed, RPA will return to
normal operation.
.The bumper is damaged. Take the vehicle
to your dealer to repair the system.
.Other conditions, such as vibrations from
a jackhammer or the compression of air
brakes on a very large truck, are affecting
system performance.
If the above conditions do not exist, take
the vehicle to your dealer to repair the
system.
Side Blind Zone Alert (SBZA)
If equipped, the SBZA system is a
lane-changing aid that assists drivers with
avoiding crashes that occur with moving
vehicles in the side blind zone (or spot)
areas. The SBZA warning display will light
up in the corresponding outside side mirror
and will flash if the turn signal is on.
{Warning
SBZA does not alert the driver to vehicles
rapidly approaching outside of the side
blind zones, pedestrians, bicyclists, (Continued)
Warning (Continued)
or animals. It may not provide alerts
when changing lanes under all driving
conditions. Failure to use proper care
when changing lanes may result in injury,
death, or vehicle damage. Before making
a lane change, always check mirrors,
glance over your shoulder, and use the
turn signals.
SBZA Detection Zones
The SBZA sensor covers a zone of
approximately one lane over from both
sides of the vehicle, or 3.5 m (11 ft). The
height of the zone is approximately between 0.5 m (1.5 ft) and 2 m (6 ft) off the ground.
This zone starts at approximately the middle
of the vehicle and goes back 5 m (16 ft).
How the System Works
The SBZA symbol lights up in the side
mirrors when the system detects a moving
vehicle in the next lane over that is in the
side blind zone. This indicates it may be
unsafe to change lanes. Before making a
lane change, check the SBZA display, check
mirrors, glance over your shoulder, and use
the turn signals.
Left Side Mirror
DisplayRight Side Mirror Display
When the vehicle is started, both outside
mirror SBZA displays will briefly come on to
indicate the system is operating. When the
vehicle is in a forward gear, the left- or
right-side mirror display will light up if a
moving vehicle is detected in that blind
zone. If the turn signal is activated in the

160 Driving and Operating
same direction of a detected vehicle, this
display will flash as an extra warning not to
change lanes.
SBZA can be disabled through vehicle
personalization. See“Collision/Detection
Systems” underVehicle Personalization 093.
If SBZA is disabled by the driver, the SBZA
mirror displays will not light up.
When the System Does Not Seem to
Work Properly
SBZA displays may not come on when
passing a vehicle quickly or for a stopped
vehicle. SBZA may alert to objects attached
to the vehicle, such as a bicycle, or object
extending out to either side of the vehicle.
This is normal system operation; the vehicle
does not need service.
SBZA may not always alert the driver to
vehicles in the side blind zone, especially in
wet conditions. The system does not need
to be serviced. The system may light up due
to guardrails, signs, trees, shrubs, and other
non-moving objects. This is normal system
operation; the vehicle does not need service.
SBZA may not operate when the SBZA
sensors in the left or right corners of the
rear bumper are covered with mud, dirt,
snow, ice, or slush, or in heavy rainstorms. For cleaning instructions, see "Washing the
Vehicle" under
Exterior Care0226. If the DIC
still displays the system unavailable
message after cleaning both sides of the
vehicle toward the rear corners of the
vehicle, see your dealer.
If the SBZA displays do not light up when
vehicles are in the blind zone and the
system is clean, the system may need
service. Take the vehicle to your dealer.
When SBZA is disabled for any reason other
than the driver turning it off, the Side Blind
Zone Alert On option will not be available
on the personalization menu.
