Automatic High-Beam System
This system turns the vehicle's
high-beam headlamps on and off
according to surrounding traffic
conditions.
The system turns the high-beam
headlamps on when it is dark
enough and there is no other traffic
present.
This light comes on in the
instrument cluster when the
automatic high-beam system is
enabled. Turning On and Enabling
Automatic High Beams
To enable the automatic high-beam
system, with the turn and
lane-change lever in the neutral
position, turn the exterior lamp
control to AUTO. The blue
high-beam on light appears on the
instrument cluster when the high
beams are on.
Driving with Automatic High
Beams
The system only activates the high

(25 mph).
There is a sensor near the top
center of the windshield, which
automatically controls the system.
Keep this area of the windshield
clear of debris to allow for best
system performance.

headlamps.
.The system detects a preceding
vehicle's taillamps.
.The outside light is bright
enough that high-beam
headlamps are not required.
.The vehicle's speed drops below
20 km/h (12 mph).
.The turn and lane-change lever
is moved forward to the
high-beam position or the
Flash-to-Pass feature is used.
SeeHeadlamp High/Low-Beam
Changer on page 6‑4 and
Flash-to-Pass on page 6‑4.
.The automatic high-beam
system can be disabled by the
High/Low-Beam Changer or the
Flash-to-Pass feature. If this
happens, the High/Low-Beam Changer must be activated two
times within five seconds to
reactivate the automatic

because of any of the following:
.The other vehicle's lamp(s) are
missing, damaged, obstructed
from view, or otherwise
undetected.
.The other vehicle's lamp(s) are
covered with dirt, snow, and/or
road spray.
.The other vehicle's lamp(s)
cannot be detected due to dense
exhaust, smoke, fog, snow, road
spray, mist, or other airborne
obstructions.
.Your vehicle's windshield is dirty,
cracked, or obstructed by
something that blocks the view
of the light sensor.
.Your vehicle's windshield is
covered with ice, dirt, haze,
or other obstructions.
.Your vehicle is loaded such that
the front end points upward,
causing the light sensor to aim
high and not detect headlamps
and taillamps.
.You are driving on winding or
hilly roads.
You may need to manually disable
or cancel the high-beam headlamps
by turning the low-beam headlamps
on, if any of the above conditions
exist.

9-10 Driving and Operating
{WARNING
Snow can trap engine exhaust
under the vehicle. This may
cause exhaust gases to get
inside. Engine exhaust contains
carbon monoxide (CO) which
cannot be seen or smelled. It can
cause unconsciousness and even
death.
If the vehicle is stuck in the snow:
.Clear away snow from around
the base of your vehicle,
especially any that is blocking
the exhaust pipe.
.Check again from time to
time to be sure snow does
not collect there.
.Open a window about 5 cm
(2 in) on the side of the
vehicle that is away from the
wind to bring in fresh air.(Continued)
WARNING (Continued)
.Fully open the air outlets on
or under the instrument
panel.
.Adjust the climate control
system to a setting that
circulates the air inside the
vehicle and set the fan speed
to the highest setting. See
“Climate Control Systems” in
the Index.
For more information about
carbon monoxide, see Engine
Exhaust on page 9‑24.
To save fuel, run the engine for only
short periods as needed to warm
the vehicle and then shut the engine
off and close the window most of
the way to save heat. Repeat this
until help arrives but only when you
feel really uncomfortable from the
cold. Moving about to keep warm
also helps. If it takes some time for help to
arrive, now and then when you run
the engine, push the accelerator
pedal slightly so the engine runs
faster than the idle speed. This
keeps the battery charged to restart
the vehicle and to signal for help
with the headlamps. Do this as little
as possible to save fuel.
If the Vehicle Is Stuck
Slowly and cautiously spin the
wheels to free the vehicle when
stuck in sand, mud, ice, or snow.
If stuck too severely for the traction
system to free the vehicle, turn the
traction system off and use the
rocking method. See
Traction
Control System (TCS) on
page 9‑34.

9-56 Driving and Operating
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 9‑42.
{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 through
vehicle personalization. See the
“Auto Collision Preparation”
portion
of “Collision/Detection Systems”
under Vehicle Personalization on
page 5‑43.
Detecting the Vehicle Ahead
FCA warnings will not occur unless
the FCA system detects a vehicle
ahead. The vehicle-ahead indicator
will display green when a vehicle is
detected in front. 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,
or ice, or if the windshield is
damaged. It may also not detect a
vehicle on winding or hilly roads,
or in conditions that can limit
visibility such as fog, rain,
or snow, or if the headlamps or
windshield are not cleaned or in
proper condition. Keep the
windshield, headlamps, and FCA
sensors clean and in good repair.

Driving and Operating 9-63
When the vehicle is started, the
LDW indicator on the instrument
cluster will come on briefly.
If LDW is on, the LDW indicator will
appear green if the system detects
a left or right lane marking while
the vehicle is traveling at 56 km/h
(35 mph) or greater. If the vehicle
crosses a detected lane marking
without using the turn signal, this
indicator will change to amber and
flash. In addition, three beeps will
sound from the left or right, or the
Safety Alert Seat will pulse three
times on either the left or right side
of the seat, depending on the lane
departure direction.
When the System Does Not
Seem to Work Properly
If the system is on and the vehicle is
travelling 56 km/h (35 mph) or
greater, and LDW symbol does not
appear:
.The lane markings on the road
may not be seen.
.The camera sensor may be
blocked by dirt, snow, or ice.
.The windshield may be
damaged.
.The weather may be limiting
visibility.
This is normal operation; the vehicle
does not need service. Clean the
windshield.
Lane markings may not be detected
on curves, highway exit ramps,
or hills; or due to poor visibility. If the LDW camera system does not
seem to operate properly, cleaning
the outside of the windshield in front
of the camera sensor may correct
the issue.
{WARNING
If the LDW camera sensor is
blocked by dirt, snow, or ice, or if
the headlamps are not cleaned or
properly aimed, or if the
windshield is dirty or damaged, it
may not detect the lanes ahead.
LDW may not help avoid a crash
under these conditions. Keep the
headlamps cleaned and properly
aimed and the windshield clean.
LDW warnings may occur due to tar
marks, shadows, cracks in the road,
or other road imperfections. This is
normal system operation; the
vehicle does not need service.
