LANE KEEPING SYSTEM – FREQUENTLY ASKED QUESTIONS
Why is the feature not available (lane markings are gray) when I can see the lane markings
on the road?
Your vehicle speed is less than 40 mph (65 km/h).
The sun is shining directly into the camera lens. A quick intentional lane change has occurred.
Your vehicle stays too close to the lane markings for an extended interval of time. Driving at high speeds in curves.
The last alert warning or aid intervention occurred a short time ago. Ambiguous lane markings, for example, in construction zones. Rapid transition from light to dark, or from dark to light. Sudden offset in lane markings.
ABS or AdvanceTrac ™ is active.
There is a camera blockage due to dirt, grime, fog, frost or water on the windshield. You are driving too close to the vehicle in front of you.
Transitioning between no lane markings to lane markings, or vice versa. There is standing water on the road.
Faint lane markings, for example, partial yellow lane markings on concrete roads. Lane width is too narrow or too wide.
You have not calibrated the camera after a windshield replacement. Driving on tight or on uneven roads.

WHAT IS PRE-COLLISION
ASSIST
Pre-collision assist detects and warns of
approaching hazards in the roadway. If
your vehicle is rapidly approaching another
stationary vehicle, a vehicle traveling in the
same direction as yours, or a pedestrian
within your driving path, the system
provides multiple levels of assistance to
help avoid a collision.
HOW DOES PRE-COLLISION
ASSIST WORK
The system warns the driver of potential
hazards by providing three levels of
assistance.
If your vehicle is rapidly approaching
potential hazards the system provides the
following levels of functionality:
1. Alert.
2. Brake Support.
3. Automatic Emergency Braking.
Alert: When active, a flashing
visual warning appears and an
audible warning tone sounds.
Brake Support
: The system is designed
to help reduce the impact speed by
preparing the brakes for rapid braking. The
system does not automatically apply the
brakes. If you press the brake pedal, the
system could apply additional braking up
to maximum braking force, even if you
lightly press the brake pedal.
Automatic Emergency Braking
:
Automatic emergency braking may
activate if the system determines that a
collision is imminent. Note:
If you perceive pre-collision assist
alerts as being too frequent or disturbing,
then you can reduce the alert sensitivity,
although the manufacturer recommends
using the highest sensitivity setting where
possible. Setting lower sensitivity would
lead to fewer and later system warnings.
Each system has various levels of
detection capabilities. See Pre-Collision
Assist Limitations
(page 397).
PRE-COLLISION ASSIST
PRECAUTIONS WARNING: You are responsible for
controlling your vehicle at all times. The
system is designed to be an aid and does
not relieve you of your responsibility to
drive with due care and attention. Failure
to follow this instruction could result in
the loss of control of your vehicle,
personal injury or death. WARNING:
The system does not
detect vehicles that are driving in a
different direction, cyclists or animals.
Apply the brakes when necessary. Failure
to follow this instruction could result in
the loss of control of your vehicle,
personal injury or death. WARNING:
The system does not
operate during hard acceleration or
steering. Failure to take care may lead
to a crash or personal injury. WARNING: The system may fail or
operate with reduced function during
cold and severe weather conditions.
Snow, ice, rain, spray and fog can
adversely affect the system. Keep the
front camera and radar free of snow and
ice. Failure to take care may result in the
loss of control of your vehicle, serious
personal injury or death.

When operating your vehicle with a
snowplow:
•
Do not exceed 45 mph (72 km/h).
• Your engine could run at a higher
temperature than normal.
•If you are driving more than
15 mi
(24 km) at temperatures above
freezing, angle the plow blade
either full left or full right to provide
maximum airflow to the radiator.
• If you are driving less than
15 mi
(24 km) at speeds up to 45 mph
(72 km/h) in cold weather, you do
not need to worry about blade
position to provide maximum
airflow.
• Shift to 4L when plowing in small areas
at speeds below
5 mph (8 km/h).
• Shift to
4H when plowing larger areas
or light snow at higher speeds above
5 mph (8 km/h)
. Do not exceed
15 mph (24 km/h).
• Do not shift the transmission from a
forward gear to reverse (R) until the
engine is at idle and the wheels have
stopped.
Note: Careless or high-speed driving when
snowplowing, which results in significant
vehicle decelerations, can deploy the airbag.
Such driving also increases the risk of
accidents.
Note: Drive your vehicle at least
500 mi
(800 km) before using your vehicle for
snowplowing.
Note: Follow the severe duty schedule for
engine oil and transmission fluid change
intervals. See
Special Operating
Conditions Scheduled Maintenance (page
675
). SNOWPLOW MODE
WHAT IS SNOWPLOW MODE
Snowplow mode reduces vehicle electrical
load to allow the electrical system to have
sufficient power to support residential
snowplow use.
SWITCHING SNOWPLOW MODE
ON AND OFF
Vehicles receive a physical button in the
instrument panel or an option in the SYNC
menu to enable snowplow mode.
Snowplow mode does not remember the
setting when you switch your vehicle off.
You must re-enable the mode every time
you wish to use it.
The following features turn off and are
disabled in snowplow mode and cannot
be turned back on until snowplow mode
is switched off:
•
120 V
inverter.
• Fog lamps.
• Heated and cooled front seats.
The body module also activates the
snowplow relay that provides power to
aftermarket snowplow controls.
Note: The electrical system supports the
addition of a residential snowplow of up to
60 A
continuous, and snowplow lights of
up to 20 A continuous using snowplow
mode. The system does not support
snowplow usage with additional electrical
aftermarket accessories.
Push Button
(If Equipped)
Press the snowplow button on the
instrument panel to switch on snowplow
mode. The snowplow button illuminates
and a message displays.
