When the indicator light on the power point
is:
•
On: The power point is working, the
ignition is ON or the vehicle is in
accessory mode.
• Off: The power point is OFF, the ignition
is OFF or the vehicle is not in accessory
mode.
• Flashing: The power point is in fault
mode.
Due to the different technologies used on
its construction, some devices may exceed
the capacity shown on its label when they
are initially plugged-in.
The power outlet temporarily turns off
power when in fault mode if the device
exceeds the 150 watt limit. Unplug your
device and switch the ignition off. Switch
the ignition back on, but do not plug your
device back in. Let the system cool off and
switch the ignition off to reset the fault
mode. Switch the ignition back on and
make sure the indicator light remains on.
Do not use the power point for certain
electric devices, including:
• Cathode-ray, tube-type televisions.
• Motor loads, such as vacuum cleaners,
electric saws and other electric power
tools or compressor-driven
refrigerators. •
Measuring devices, which process
precise data, such as medical
equipment or measuring equipment.
• Other appliances requiring an
extremely stable power supply such as
microcomputer-controlled electric
blankets or touch-sensor lamps.
WIRELESS ACCESSORY
CHARGER (IF EQUIPPED) WARNING:
Wireless charging
devices can affect the operation of
implanted medical devices, including
cardiac pacemakers. If you have any
implanted medical devices, we
recommend that you consult with your
physician.
Note: Devices without built-in Qi wireless
charging receivers require an additional Qi
receiver or sleeve.
Note: For compatible devices with built-in
Qi wireless charging capability, the charging
performance may be affected if your device
is in a case. It may be necessary to remove
the case to wirelessly charge your device.
The system supports one Qi wireless
charging compatible device on the
charging area.
Keep the charging area clean and remove
foreign objects prior to charging a device.
Do not place items with a magnetic strip,
for example passports, parking tickets or
credit cards, near the charging area when
charging a device. Damage may occur to
the magnetic strip.
Do not place metal objects, for example
remote controls, coins and candy
wrappers, on or near the charging area
when charging a device. Metal objects may
heat up and degrade the charging
performance.

EMISSION LAW
WARNING: Do not remove or alter
the original equipment floor covering or
insulation between it and the metal floor
of the vehicle. The floor covering and
insulation protect occupants of the
vehicle from the engine and exhaust
system heat and noise. On vehicles with
no original equipment floor covering
insulation, do not carry passengers in a
manner that permits prolonged skin
contact with the metal floor. Failure to
follow these instructions may result in
fire or personal injury.
U.S. federal laws and certain state laws
prohibit removing or rendering inoperative
emission control system components.
Similar federal or provincial laws may
apply in Canada. We do not approve of any
vehicle modification without first
determining applicable laws. Tampering with emissions
control systems including
related sensors or the Diesel
Exhaust Fluid system can result in reduced
engine power and the illumination of the
service engine soon light. Tampering With a Noise Control
System
Federal laws prohibit the following acts:
•
Removal or rendering inoperative by
any person other than for purposes of
maintenance.
• Repair or replacement of any device or
element of the design incorporated into
a new vehicle for the purpose of noise
control prior to its sale or delivery to
the ultimate purchaser or while it is in
use.
• The use of the vehicle after any person
removes or renders inoperative any
device or element of the design.
The U.S. Environmental Protection Agency
may presume to constitute tampering as
follows:
• Removal of hood blanket, fender apron
absorbers, fender apron barriers,
underbody noise shields or acoustically
absorptive material.
• Tampering or rendering inoperative the
engine speed governor, to allow engine
speed to exceed manufacturer
specifications.
If the engine does not start, runs rough,
experiences a decrease in engine
performance, experiences excess fuel
consumption or produces excessive
exhaust smoke, check for the following:
• A plugged or disconnected air inlet
system hose.
• A plugged engine air filter element.
• Water in the fuel filter and water
separator.
• A clogged fuel filter.
• Contaminated fuel.
• Air in the fuel system, due to loose
connections.
• An open or pinched sensor hose.
• Incorrect engine oil level.
