If required, switch the entire
pre-collision assist feature on or off.
• If required, switch evasive steering
assist on or off.
Note: Automatic emergency braking and
evasive steering turn on every time you
switch the ignition on.
Note: If your vehicle has a radar sensor, we
recommend that you switch the system off
if you install a snow plow or similar object

LOCATING THE PRE-
COLLISION ASSIST SENSORS
- POLICE RESPONDER Camera.
1 If a message regarding a blocked camera
appears in the instrument cluster display,
something is obstructing the camera
images. With a blocked camera, the
system may not function, or performance
may reduce. See Pre-Collision Assist –
Information Messages (page 404).
Note: Proper system operation requires a
clear view of the road by the camera. Have
any windshield damage in the area of the
camera's field of view repaired.
Note: If your vehicle detects excessive heat
at the camera or a potential misalignment
condition, a message could display in the
information display indicating temporary
sensor unavailability. When operational
conditions are correct, the message
deactivates. For example, when the ambient
temperature around the sensor decreases
or the sensor recalibrates successfully.

following occur:
•
The wheels are not pointed straight
ahead.
• Your vehicle is not in park (P).
• Your vehicle is not on a level surface.
• The tire pressures are below the
recommended levels.
• Your vehicle is off.

What does it mean if the system
displays that it is not available?
There could be a sub-system that the
system uses that is not correctly
operating or there could be a battery
voltage issue. If the system continues
to display it is not available, visit your
authorized dealer to have your vehicle
checked.
What does it mean if the system
displays that driving is required to
initialize steering? The steering system needs to learn
internal parameters to fully turn on the
feature. Drive your vehicle straight
forward above 25 mph (40 km/h) for
approximately 5 minutes. This could
also occur when your vehicle is new,
there is a battery voltage issue or if the
steering system has been serviced.
What does it mean if the system does
not detect a trailer when configured
with a sensor? Verify that the sensor is properly
connected. See
Trailer Sensor
Installation (page 448). Repeat
calibration on a different route if you
have verified sensor installation.
What does it mean if the system
requires you to pull forward to
initialize? This occurs when the vehicle has not
moved during the current key cycle
after you connect and select the trailer
in the touchscreen or you operate the
system at speeds below
1 mph
(1 km/h) for an extended period of
time. Drive forward above 2 mph
(3 km/h) and the system indicates
when it initializes. What does it mean if the trailer is at its
maximum angle or the system
deactivated by trailer angle?
You are at the maximum controllable
trailer angle for the system. Place your
vehicle in drive (D) and pull forward to
get the truck and trailer back to an
in-line position. If this message
consistently displays, this could
indicate the sensor is incorrectly
installed, the trailer needs to be
recalibrated or the drawbar or the
trailer dimensions are outside of the
supported range. The system is
designed to work with drawbars that
have a license plate to hitch ball center
measurement of
9–18 in (23–46 cm)
when installed. The system is designed
to work with trailers that have a hitch
point to center of the axle or axles
measurement of
6– 33 ft
(1.85– 10.05 m). Do not attempt to use
drawbars or trailers that have a length
outside of this range as the system
performance degrades and could
cause improper system function.
Check that the correct trailer is
selected in the touchscreen. Verify the
sensor is installed according to the
instructions included in the sensor kit
and check that the drawbar and the
trailer dimensions are within the
allowed range. Then, delete the trailer
from the system and repeat the setup
process to calibrate the trailer.

Driving In Mud
Be cautious of sudden changes in vehicle
speed or direction when you are driving in
mud.
After driving through mud, clean your
vehicle. Excess mud stuck on the wheels
and tires and rotating components can
cause an imbalance and result in damage.
Note:
The vehicle brakes are less effective
when wet or muddy.
Driving Over Rocks and Gravel
Never attempt to straddle a rock that is
large enough to strike your axles or
undercarriage.
Leave a generous gap between your
vehicle and other vehicles to minimize the
risk of damage. Avoid dust clouds as they
reduce visibility.
Climbing A Hill WARNING: Extreme care should
be used when steering the vehicle in
reverse down a slope so as not to cause
the vehicle to swerve out of control.
Do not drive over the crest of a hill without
seeing what conditions are on the other
side. Do not drive in reverse over a hill
without the aid of an observer.
Note: Avoid turning on steep slopes or hills.
A danger lies in losing traction, slipping
sideways and possible vehicle roll over.
Note: Too much acceleration can cause
the tires to slip, spin or lose traction,
resulting in loss of vehicle control. Driving Through Water WARNING:
Do not attempt to
cross a deep, fast flowing body of water.
Failure to follow this instruction could
result in the loss of control of your
vehicle, personal injury or death.
The key to a safe crossing is the water
depth, current and bottom of the water's
condition. On soft bottoms, the vehicle
sinks in, effectively increasing the water
level on the vehicle. Make sure to consider
this when determining the depth of water.
Determine the depth and speed of the
current before attempting a water crossing.
Be aware that obstacles and debris could
be beneath the water ’s surface.
Note: Cross flowing water at an angle
heading slightly upstream.
Note: Tread lightly and avoid damage to
the environment.
Water can cause permanent damage that
may not be covered by your vehicle
warranty. See
Driving Through Water
Limitations (page 474).
Note: Failure to follow the recommended
speeds can result in vehicle damage.
Muddy waters can reduce the cooling
system effectiveness by depositing debris
into the radiator.
High currents even in shallow water can
wash the dirt out from around your tires or
push your vehicle across slippery rocks or
surfaces.
Do not cross any body of water that is fast
flowing and rising.

HIGH VOLTAGE BATTERY
VEHICLE PRECAUTIONS -
HYBRID ELECTRIC VEHICLE
(HEV)
In the event of damage or fire involving an
electric vehicle or hybrid-electric vehicle:
• Assume the high-voltage battery and
associated components are energized
and fully charged.
• Physical damage to the vehicle or
high-voltage battery could result in
immediate or delayed release of toxic,
flammable gases and fire.
Crashes
A crash or impact significant enough to
require an emergency response for
conventional vehicles would also require
the same response for an electric or
hybrid-electric vehicle. If Possible:
1. Move your vehicle to a safe, nearby
location and remain on the scene.
2. Roll down the windows before you switch your vehicle off.
3. Place your vehicle in park (P), apply the parking brake, switch off the
vehicle, turn on the hazard flashers and
move the key at least 16 ft (5 m) away
from the vehicle.
Always:
• Call emergency assistance if needed
and advise that an electric or
hybrid-electric vehicle is involved.
• Avoid contact with leaking fluids and
gases, and remain out of the way of
oncoming traffic until emergency
responders arrive.
• When emergency responders arrive,
tell them that the vehicle involved is an
electric vehicle or hybrid-electric
vehicle.
Fires
As with any vehicle, call emergency
assistance immediately if you see sparks,
smoke or flames coming from the vehicle.
Remain a safe distance from the vehicle
and try to stay clear of the smoke.
1. Exit the vehicle immediately.
2. Advise emergency assistance that an electric or hybrid-electric vehicle is
involved.
3. As with any vehicle fire, do not inhale smoke, vapors or gas from the vehicle,
as they may be hazardous.
