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
OFF or to the Parking Lamp position
to disable this feature.

Turn and Lane-Change
Signals
An arrow on the instrument panel
cluster will flash in the direction of
the turn or lane change.
Move the lever all the way up or
down to signal a turn.
Raise or lower the lever until the
arrow starts to flash to signal a lane
change. Hold it there until the lane
change is complete. If the lever is
briefly pressed and released, the
turn signal flashes three times.
The lever returns to its starting
position when it is released.
If after signaling a turn or a lane
change the arrows flash rapidly or
do not come on, a signal bulb may
be burned out.

6-6 Lighting
The battery can be discharged at
idle if the electrical loads are very
high. This is true for all vehicles.
This is because the generator
(alternator) may not be spinning fast
enough at idle to produce all of the
power needed for very high
electrical loads.
A high electrical load occurs when
several of the following are on, such
as: headlamps, high beams, fog
lamps, rear window defogger,
climate control fan at high speed,
heated seats, engine cooling fans,
trailer loads, and loads plugged into
accessory power outlets.EPM works to prevent excessive
discharge of the battery. It does this
by balancing the generator's output
and the vehicle's electrical needs.
It can increase engine idle speed to
generate more power whenever
needed. It can temporarily reduce
the power demands of some
accessories.
Normally, these actions occur in
steps or levels, without being
noticeable. In rare cases at the
highest levels of corrective action,
this action may be noticeable to the
driver. If so, a DIC message might
be displayed and it is recommended
that the driver reduce the electrical
loads as much as possible. See
Battery Voltage and Charging
Messages on page 5‑24.

9-8 Driving and Operating
.Use headlamps even during the
day to make the vehicle more
visible.
{WARNING
Driving to the top of a hill at high
speed can cause an accident.
There could be a drop-off,
embankment, cliff, or even
another vehicle. You could be
seriously injured or killed. As you
near the top of a hill, slow down
and stay alert.
.Never go downhill forward or
backward with the transmission
in N (Neutral). The brakes could
overheat and you could lose
control.
.When driving down a hill, keep
the vehicle headed straight
down. Use a low gear because
the engine will work with the
brakes to slow the vehicle and
help keep the vehicle under
control.
{WARNING
Heavy braking when going down
a hill can cause your brakes to
overheat and fade. This could
cause loss of control and you or
others could be injured or killed.
Apply the brakes lightly when
descending a hill and use a low
gear to keep vehicle speed under
control.
If the vehicle stalls on a hill:
1. Apply the brakes to stop the vehicle, and then apply the
parking brake.
2. Shift into P (Park) and then restart the engine.
.If driving uphill when the
vehicle stalls, shift to
R (Reverse), release the
parking brake, and back
straight down.
.Never try to turn the vehicle
around. If the hill is steep
enough to stall the vehicle,
it is steep enough to cause
it to roll over.
.If you cannot make it up the
hill, back straight down
the hill.
.Never back down a hill in
N (Neutral) using only the
brake.
.The vehicle can roll
backward quickly and you
could lose control.
.If driving downhill when the
vehicle stalls, shift to a
lower gear, release the
parking brake, and drive
straight down the hill.
3. If the vehicle cannot be restarted after stalling, set the parking
brake, shift an automatic
transmission into P (Park), and
turn the vehicle off.
3.1. Leave the vehicle and seek help.

Blizzard Conditions
Being stuck in snow can be a
serious situation. Stay with the
vehicle unless there is help nearby.
If possible, use Roadside
Assistance. SeeRoadside
Assistance Program (Mexico) on
page 13‑7 orRoadside Assistance
Program (U.S. and Canada) on
page 13‑11. To get help and keep
everyone in the vehicle safe:
.Turn on the hazard warning
flashers.
.Tie a red cloth to an outside
mirror.
{WARNING
Snow can trap engine exhaust
under the vehicle. This may
cause exhaust gases to get
inside. Engine exhaust contains
carbon monoxide (CO) which
(Continued)
WARNING (CONTINUED)
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.
.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(Continued)
WARNING (CONTINUED)
to the highest setting. See
“Climate Control Systems” in
the Index.
For more information about
carbon monoxide, see Engine
Exhaust on page 9‑25.
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.

Detecting the Vehicle Ahead
The green vehicle ahead indicator
will appear when a vehicle is
detected ahead. Whenever this
indicator does not appear, FCA will
not respond. The indicator may
disappear on curves, highway exit
ramps, or hills, or due to poor
visibility. The FCA system 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,(Continued)
WARNING (CONTINUED)
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.
Collision Alert
When your vehicle approaches
another vehicle too rapidly, the red
FCA display will flash and sound
several beeps. When this occurs,
the brake system prepares for driver braking to occur more rapidly.
Continue to apply the brake pedal
as the driving situation dictates.
Tailgating Alert
The red FCA display will stay
continuously illuminated if the
vehicle ahead remains much too
close.
Selecting the Alert Timing
The Collision Alert control is on the
steering wheel. Press COLLISION
ALERT to set the alert timing to far,
medium, near or off. The first button

LDW operates at speeds of 56 km
(35 mph) or greater. If LDW is on,
the LDW indicator will appear green
if the system detects a left or right
lane marking. This indicator will
change to amber, flash, and three
chimes will sound if the vehicle
crosses a detected lane marking
without using the turn signal.
To change the volume of the
warning chime, see“Chime Volume”
under Vehicle Personalization on
page 5‑31 for more information.
When the System Does Not
Seem To Work Properly
If the 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.
{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 occasionally
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. LDW Messages

activate during heavy rain or due to
road spray.
LANE DEPARTURE SYSTEM
UNAVAILABLE: This message
may appear if LDW does not
activate due to a temporary
condition.
SERVICE FRONT CAMERA: This
message may appear to indicate
that LDW is not working properly.
If this message remains on after
continued driving, the system needs
service. Take the vehicle to your
dealer.
