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 turns on the
low-beam headlamps at a reduced
brightness. For vehicles with High
Intensity Discharge (HID)
headlamps, there is a dedicated
DRL. The DRL will come on when
all of the following conditions
are met:
.The ignition is on.
.The exterior lamp control is
in AUTO.
.The light sensor determines it is
daytime.
.The parking brake is released or
the vehicle is not in P (Park).
The taillamps, sidemarker lamps,
instrument panel lights, and other
lamps will not be on.
The DRL turn off when the
headlamps are turned to

The system may also turn on the
headlamps when driving through a
parking garage or tunnel.
If the vehicle is started in a dark
garage, the automatic headlamp
system comes on immediately. If it
is light outside when the vehicle
leaves the garage, there is a slight
delay before the automatic
headlamp system changes to the
DRL. During that delay, the
instrument cluster may not be as
bright as usual. Make sure the
instrument panel brightness control
is in the full bright position. See
Instrument Panel Illumination
Control on page 6-6.
When it is bright enough outside,
the headlamps will turn off or may
change to Daytime Running
Lamps (DRL).
The automatic headlamp system
turns off when the exterior lamp
control is turned to
Oor the ignition
is off.
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
P
or;to disable this feature.
Adaptive Forward
Lighting (AFL)
On vehicles with the AFL system,
the headlamps pivot horizontally to
provide greater road illumination
while turning. To enable AFL, set
the exterior lamp control on the turn
signal lever to the AUTO position.
Moving the control out of the AUTO
position will deactivate the system.
AFL will operate when the vehicle
speed is greater than 3 km/h
(2 mph). AFL will not operate when the transmission is in R (Reverse).
AFL is not immediately operable
after starting the vehicle; driving a
short distance is required to
calibrate the AFL. See

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.

9-16 Driving and Operating
.Do not let the engine labor.
Never lug the engine in high
gear at low speeds. With a
manual transmission, shift to the
next lower gear. This rule
applies at all times, not just
during the break-in period.
.Check engine oil with every
refueling and add if necessary.
Oil and fuel consumption may be
higher than normal during the
first 2 414 km (1,500 mi).
.New brake linings also need a
break-in period. Avoid making
hard stops during the first
322 km (200 mi). This is
recommended every time brake
linings are replaced.
Ignition Positions
The vehicle has an electronic
keyless ignition with pushbutton
start.
Pressing the button cycles it through
three modes: ACC/ACCESSORY,
ON/RUN/START, and Stopping the
Engine/OFF.
The Remote Keyless Entry (RKE)
transmitter must be in the vehicle for
the system to operate. If the
pushbutton start is not working, the
vehicle may be near a strong radio
antenna signal causing interferenceto the Keyless Access system. See
Remote Keyless Entry (RKE)
System Operation on page 2-2.
To shift out of P (Park), the vehicle
must be in ON/RUN/START and the
brake pedal must be applied.
Stopping the Engine/OFF (No
Indicator Lights):
When the
vehicle is stopped, press the
ENGINE START/STOP button once
to turn the engine off.
If the vehicle is in P (Park), the
ignition will turn off, and Retained
Accessory Power (RAP) will remain
active. See Retained Accessory
Power (RAP) on page 9-21.
Automatic Transmission
If the vehicle is not in P (Park), the
ignition will return to ACC/
ACCESSORY and display a
message in the Driver Information
Center (DIC). See Transmission
Messages on page 5-42. When the
vehicle is shifted into P (Park), the
ignition system will switch to OFF.

(SBZA), Lane Change Alert (LCA),
and/or the Active Emergency
Braking System can help to avoid a
crash or reduce crash damage.
Forward Collision Alert
(FCA) System
If equipped, the FCA system may
help to avoid or reduce the harm
caused by front-end crashes. When
approaching a vehicle ahead too
quickly, FCA provides a flashing red
alert on the windshield and rapidly
beeps or pulses the Safety Alert
Seat. FCA also lights an amber
visual alert if following another
vehicle much too closely.
FCA detects vehicles within a
distance of approximately 60 m
(197 ft) and operates at speeds
above 40 km/h (25 mph). If the
vehicle has Adaptive Cruise Control
(ACC), it can detect vehicles to
distances of approximately 110 m
(360 ft) and operates at all speeds.
SeeAdaptive Cruise Control on
page 9-41.
{Warning
FCA is a warning system and
does not apply the brakes. When
approaching a slower-moving or
stopped vehicle ahead too rapidly,
or when following a vehicle too
closely, FCA may not provide a
warning with enough time to help
avoid a crash. FCA does not warn
of pedestrians, animals, signs,
guardrails, bridges, construction
barrels, or other objects. Be ready
to take action and apply the
brakes. For more information, see
Defensive Driving on page 9-3.
FCA can be disabled with the FCA
steering wheel control, or if your
vehicle is equipped with Adaptive
Cruise Control (ACC), through
vehicle personalization. See the
“Auto Collision Preparation” portion
of “Collision/Detection Systems”
under Vehicle Personalization on
page 5-44.
Detecting the Vehicle Ahead
FCA warnings will not occur unless
the FCA system detects a vehicle
ahead. When a vehicle is detected,
the vehicle-ahead indicator will
display green. Vehicles may not be
detected on curves, highway exit
ramps, or hills; or due to poor
visibility. FCA will not detect another
vehicle ahead until it is completely
in the driving lane.
{Warning
FCA does not provide a warning
to help avoid a crash, unless it
detects a vehicle. FCA may not
detect a vehicle ahead if the FCA
sensor is blocked by dirt, snow,

1. SBZA Detection Zone
2. LCA Detection Zone
LCA Detection Zones
The LCA 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. The
Side Blind Zone Alert (SBZA)
warning area starts at approximately
the middle of the vehicle and goes
back 5 m (16 ft). Drivers are also
warned of vehicles rapidly
approaching from up to 25 m (82 ft)
behind the vehicle.
How the System Works
The LCA symbol lights up in the
side mirrors when the system
detects a vehicle in the next lane
over that is in the side blind zone or
rapidly approaching from behind.
A lit LCA symbol indicates it may be
unsafe to change lanes. Before
making a lane change, check the
LCA display, check mirrors, glance
over your shoulder, and use the turn
signals.
Left Side MirrorDisplayRight Side Mirror Display
When the vehicle is started, both
outside mirror LCA displays will
briefly come on to indicate the
system is operating. When the
vehicle is moving forward, the left-
or right-side mirror display will light
up if a vehicle is detected in the next lane over in that blind zone or
rapidly approaching that zone. If the
turn signal is activated in the same
direction as a detected vehicle, this
display will flash as an extra
warning not to change lanes.
LCA can be disabled through
vehicle personalization. See
“Collision/Detection Systems”
under
Vehicle Personalization on
page 5-44. If LCA is disabled by the
driver, the LCA mirror displays will
not light up.
When the System Does Not
Seem to Work Properly
The LCA system requires some
driving for the system to calibrate to
maximum performance. This
calibration may occur more quickly if
the vehicle is driving on a straight
highway road with traffic and
roadside objects (e.g., guardrails,
barriers).
LCA displays may not come on
when passing a vehicle quickly or
when towing a trailer. The LCA
detection zones that extend back

plugged in during the jump
starting procedure, they could be
damaged. The repairs would not
be covered by the vehicle
warranty. Whenever possible, turn
off or unplug all accessories on
either vehicle when jump starting. 4. Set the ignition to OFF. Turn off
all lights and accessories in both
vehicles, except the hazard
warning flashers if needed.
