Noise Emissions Warranty, Prohibited
Tampering Acts and Maintenance
On January 1, 1978, Federal regulation
became effective governing the noise
emission on trucks over 10,000 lb (4,536 kg)
Gross Vehicle Weight Rating (GVWR). The
preceding statements concerning prohibited
tampering acts and maintenance, and the
noise warranty found in the Warranty Guide,
are applicable to complete chassis cabs over
10,000 lb (4,536 kg) GVWR.
CATALYTIC CONVERTER
WARNING: Do not park, idle or drive
your vehicle on dry grass or other dry
ground cover. The emission system heats
up the engine compartment and exhaust
system, creating the risk of fire.
WARNING: The normal operating
temperature of the exhaust system is very
high. Never work around or attempt to
repair any part of the exhaust system until
it has cooled. Use special care when
working around the catalytic converter.
The catalytic converter heats up to a very
high temperature after only a short period
of engine operation and stays hot after the
engine is switched off.
WARNING: Exhaust leaks may result
in entry of harmful and potentially lethal
fumes into the passenger compartment. If
you smell exhaust fumes inside your
vehicle, have your vehicle inspected
immediately. Do not drive if you smell
exhaust fumes.Your vehicle has various emission control
components and a catalytic converter that
enables it to comply with applicable exhaust
emission standards.
To make sure that the catalytic converter and
other emission control components continue
to work properly:
• Do not crank the engine for more than
10 seconds at a time.
• Do not run the engine with a spark plug
lead disconnected.
• Do not push-start or tow-start your
vehicle. Use booster cables. See Jump
Starting the Vehicle (page 366).
• Use only the specified fuel listed.
• Do not switch the ignition off when your
vehicle is moving.
• Avoid running out of fuel.
• Have the items listed in scheduled
maintenance information performed
according to the specified schedule.
Note:Resulting component damage may
not be covered by the vehicle Warranty.

Engine Emission Control

Note:When plugging into an unfamiliar wall
outlet, let the vehicle charge for several
minutes before leaving it unattended. The
red indicator will illuminate if not charging.
The unit will turn off if breaker or
infrastructure ground fault circuit interrupter
(GFCI) is tripped. You can view vehicle
charging status remotely via the Lincoln Way
App.
Mobile Power Cord Auto-Restart
Auto-restart helps to make sure that your
vehicle will be charged and ready for use
when needed. A charge could be interrupted
if errors are detected. Charging resumes
once the error is no longer detected. The
red indicator illuminates during an error
condition.
The exception to the immediate auto-restart
is when the interruption is due to a charger
ground fault circuit interrupter (GFCI) event.
The charger attempts to restart 15 minutes
after a ground fault circuit interrupter (GFCI)
event. After the fourth attempt to restart, the
charger shuts down and the red indicator
stays on.If the fault persists, do not continue to try to
charge your vehicle. Contact your authorized
dealer.
CARE INSTRUCTIONS
Do not use cleaners or solvents as this could
damage your mobile power cord. Do not
place stress on the charger cables. If unit
overheats, remove the mobile power cord
from direct sunlight.
SAFETY FEATURES
The charger includes the following safety
features to protect against the risk of electric
shock:
• Service Ground Check: The charger
constantly checks for the presence of a
service ground connection. If the service
ground ever fails, the charger red
indicator turns ON and shuts down power
to the vehicle.
• Thermal Event Sensor: Charger module
senses out-of-ordinary thermal events
and decreases the charging current or
shuts the unit down if required.• Ground fault circuit interrupter (GFCI)
Protection: The charger has a ground
fault circuit interrupter (GFCI) reaction
system to protect against electric shock.
If the charger module detects an output
ground fault, it shuts down power to the
output cable and illuminates the red
indicator.
• Insulation: The charger module,
connector, cable assembly, and charge
coupler are completely insulated. There
are no exposed live parts, to protect
against electric shock.
• Unintentional Disconnection: The charge
coupler is designed to minimize
unintentional disconnection. A pilot signal
wire in the cable and charge coupler
eliminates the possibility of electric shock
when not connected to a vehicle or if an
unintended disconnect occurs during a
charge. Disconnection during charging
is safe.

HILL START ASSIST
WARNING: The system does not
replace the parking brake. When you leave
your vehicle, always apply the parking
brake.
WARNING: You must remain in your
vehicle when the system turns on. At all
times, you are responsible for controlling
your vehicle, supervising the system and
intervening, if required. Failure to take care
may result in the loss of control of your
vehicle, serious personal injury or death.
WARNING: The system will turn off
if a malfunction is apparent or if you rev
the engine excessively. Failure to take care
may result in the loss of control of your
vehicle, serious personal injury or death.
The system makes it easier to pull away
when your vehicle is on a slope without the
need to use the parking brake.When the system is active, your vehicle
remains stationary on the slope for two to
three seconds after you release the brake
pedal. This allows time to move your foot
from the brake to the accelerator pedal. The
system releases the brakes automatically
once the engine has developed sufficient
torque to prevent your vehicle from rolling
down the slope. This is an advantage when
pulling away on a slope, for example from a
car park ramp, traffic lights or when reversing
uphill into a parking space.
The system activates on any slope that
causes your vehicle to roll.
Note:There is no warning light to indicate
the system is either on or off.
Using Hill Start Assist
1. Press the brake pedal to bring your
vehicle to a complete standstill. Keep the
brake pedal pressed and shift into first
gear when facing uphill or reverse (R)
when facing downhill.
2. If the sensors detect that your vehicle is
on a slope, the system activates
automatically.3. When you remove your foot from the
brake pedal, your vehicle remains on the
slope without rolling away for about two
to three seconds. This hold time
automatically extends if you are in the
process of driving off.
4. Drive off in the normal manner. The
system releases the brakes automatically.
Note:When you remove your foot from the
brake pedal and press the pedal again when
the system is active, you will experience
significantly reduced brake pedal travel. This
is normal.
Switching the System On and Off
Vehicles with Manual Transmission
You can switch this feature on or off in the
information display. The system remembers
the last setting when you start your vehicle.
Vehicles with Automatic Transmission
You cannot turn the system on or off. When
you switch the ignition on, the system
automatically turns on.

WHAT IS REVERSE BRAKING
ASSIST
E205199E205199
Reverse braking assist is designed to reduce
impact damage or assist in avoiding a
collision while in reverse (R). Using sensors
on the rear of the vehicle, it can detect a
possible collision and apply the brakes. If full
braking occurs, the system attempts to stop
the vehicle a safe distance from the obstacle.
HOW DOES REVERSE BRAKING
ASSIST WORK
Reverse braking assist functions when in
reverse (R) and traveling at a speed of
1–7 mph (2–12 km/h).If the system detects an obstacle behind your
vehicle, it provides a warning through the
rear parking aid or cross traffic alert system.
REVERSE BRAKING 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: To help avoid personal
injury, always use caution when in reverse
(R) and when using the sensing system.
WARNING: The system may not
operate properly during severe weather
conditions, for example snow, ice, heavy
rain and spray. Always drive with due care
and attention. Failure to take care may
result in a crash.
WARNING: Traffic control systems,
fluorescent lamps, inclement weather, air
brakes, external motors and fans may
affect the correct operation of the sensing
system. This may cause reduced
performance or false alerts.
WARNING: Some situations and
objects prevent hazard detection. For
example low or direct sunlight, inclement
weather, unconventional vehicle types, and
pedestrians. Apply the brakes when
necessary. Failure to follow this instruction
could result in the loss of control of your
vehicle, personal injury or death.

Reverse Braking Assist (If Equipped)

WARNING: Do not use the system
with accessories that extend beyond the
front or rear of your vehicle, for example a
trailer hitch or bike rack. The system is not
able to make corrections for the additional
length of the accessories.
The system only applies the brakes for a
short period of time when an event occurs.
Act as soon as you notice the brakes apply
to remain in control of the vehicle. If you do
not intervene the vehicle may start to move
again.
Note:Certain add-on devices around the
bumper or fascia may create false alerts. For
example, large trailer hitches, bicycle or
surfboard racks, license plate brackets,
bumper covers or any other device that may
block the normal detection zone of the
system. Remove the add-on device to
prevent false alerts.
Note:The system does not react to small or
moving objects, particularly those close to
the ground.Note:The system does not operate during
hard acceleration or steering.
Note:If your vehicle sustains damage to the
bumper or fascia leaving it misaligned or
bent, it could alter the sensing zone causing
inaccurate measurement of obstacles or
false alerts.
Note:Vehicle loading and suspension
changes can impact the angle of the sensors
and may change the normal detection zone
of the system resulting in inaccurate
measurement of obstacles or false alerts.
Note:When you connect a trailer, the system
may detect the trailer and provide an alert,
or the system turns off. If the system does
not turn off, manually switch the system off
after you connect the trailer.
Note:You may experience reduced system
performance on road surfaces that limit
deceleration. For example, roads with ice,
loose gravel, mud or sand.

Reverse Braking Assist (If Equipped)

PRINCIPLE OF OPERATION
WARNING: Vehicle modifications
involving braking system, aftermarket roof
racks, suspension, steering system, tire
construction and wheel and tire size may
change the handling characteristics of your
vehicle and may adversely affect the
performance of the electronic stability
control system. In addition, installing any
stereo loudspeakers may interfere with
and adversely affect the electronic stability
control system. Install any aftermarket
stereo loudspeaker as far as possible from
the front center console, the tunnel, and
the front seats in order to minimize the risk
of interfering with the electronic stability
control sensors. Reducing the
effectiveness of the electronic stability
control system could lead to an increased
risk of loss of vehicle control, vehicle
rollover, personal injury and death.
WARNING: Remember that even
advanced technology cannot defy the laws
of physics. It’s always possible to lose
control of a vehicle due to inappropriate
driver input for the conditions. Aggressive
driving on any road condition can cause
you to lose control of your vehicle
increasing the risk of personal injury or
property damage. Activation of the
electronic stability control system is an
indication that at least some of the tires
have exceeded their ability to grip the
road; this could reduce the operator’s
ability to control the vehicle potentially
resulting in a loss of vehicle control, vehicle
rollover, personal injury and death. If your
electronic stability control system activates,
SLOW DOWN.
The system automatically turns on each time
you switch the ignition on.
If a driving condition activates either the
stability control or the traction control system
you may experience the following conditions:• The stability and traction control light
flashes.
• Your vehicle slows down.
• Reduced engine power.
• A vibration in the brake pedal.
• The brake pedal is stiffer than usual.
• If the driving condition is severe and your
foot is not on the brake, the brake pedal
may move as the systems applies higher
brake forces.
The stability control system has several
features built into it to help you maintain
control of your vehicle:
Electronic Stability Control
The system enhances your vehicle’s ability
to prevent skids or lateral slides by applying
brakes to one or more of the wheels
individually and, if necessary, reducing
engine power.
