Seats and Restraints 69
Seat Belt Use During
Pregnancy
Seat belts work for everyone,
including pregnant women. Like all
occupants, they are more likely to
be seriously injured if they do not
wear seat belts.
A pregnant woman should wear a
lap-shoulder belt, and the lap
portion should be worn as low as
possible, below the rounding,
throughout the pregnancy.
The best way to protect the fetus is
to protect the mother. When a seat
belt is worn properly, it is more likelythat the fetus will not be hurt in a
crash. For pregnant women, as for
anyone, the key to making seat
belts effective is wearing them
properly.
Seat Belt Extender
If the vehicle's seat belt will fasten
around you, you should use it.
But if a seat belt is not long enough,
your dealer will order you an
extender. When you go in to order it,
take the heaviest coat you will wear,
so the extender will be long enough
for you. To help avoid personal
injury, do not let someone else use
it, and use it only for the seat it is
made to fit. The extender has been
designed for adults. Never use it for
securing child restraints. For more
information on the proper use and fit
of seat belt extenders see the
instruction sheet that comes with
the extender.
Safety System Check
Periodically check the seat belt
reminder, seat belts, buckles, latch
plates, retractors, shoulder belt
height adjusters (if equipped), and
seat belt anchorages to make sure
they are all in working order. Look
for any other loose or damaged seat
belt system parts that might keep a
seat belt system from performing
properly. See your dealer to have it
repaired. Torn, frayed, or twisted
seat belts may not protect you in a
crash. Torn or frayed seat belts can
rip apart under impact forces. If a
belt is torn or frayed, have it
replaced immediately. If a belt is
twisted, it may be possible to
untwist by reversing the latch plate
on the webbing. If the twist cannot
be corrected, ask your dealer to
fix it.
Make sure the seat belt reminder
light is working. See
Seat Belt
Reminders 0120.
Keep seat belts clean and dry. See
Seat Belt Care 070.

110 Instruments and Controls
The indicator light does not come on
when the ignition is off or if the
equipment is not fully seated into
the outlet.
If you try to connect equipment
using more than 150 watts or a
system fault is detected, the
equipment may operate for a short
period and turn itself off.
A protection circuit shuts off the
power supply and the indicator light
turns off. To reset the circuit, unplug
the item and plug it back in or turn
the Remote Accessory Power (RAP)
off and then back on. SeeRetained
Accessory Power (RAP) 0181.
Prolonged use of the power outlet at
the maximum load of 150 watts may
cause the outlet to overheat and
automatically shut down. The power
restarts when equipment that
operates within the limit is plugged
into the outlet and a system fault is
not detected.
The power outlet is not designed for
the following equipment, and may
not work properly if any of the
following is plugged in: .
Equipment with high initial peak
wattage, such as
compressor-driven refrigerators
and electric power tools
. Other equipment requiring an
extremely stable power supply,
such as
microcomputer-controlled
electric blankets, and touch
sensor lamps
. Medical equipment
Wireless Charging
The vehicle may have a wireless
charging pocket outside the armrest
of the center console. The system
operates at 145 kHz and wirelessly
charges one Qi compatible
smartphone. The power output of
the system is capable of charging at
a rate up to 1 amp (5W), as
requested by the compatible
smartphone. See Radio Frequency
Statement 0345.
{Warning
Wireless charging can affect the
operation of an implanted
pacemaker or other medical
devices. If you have one, it is
recommended to consult with
your doctor before using the
wireless charging system.
The vehicle must be on or in ACC/
ACCESSORY, or Retained
Accessory Power (RAP) must be
active. The wireless charging
feature may not correctly indicate
charging when the vehicle is in RAP.
See Retained Accessory Power
(RAP) 0181.
{Warning
Remove all objects from the
charging pocket before charging
your compatible smartphone.

Battery Load
Management
The vehicle has Electric Power
Management (EPM) that estimates
the battery's temperature and state
of charge. It then adjusts the voltage
for best performance and extended
life of the battery.
When the battery's state of charge
is low, the voltage is raised slightly
to quickly bring the charge back up.
When the state of charge is high,
the voltage is lowered slightly to
prevent overcharging. If the vehicle
has a voltmeter gauge or a voltage
display on the Driver Information
Center (DIC), you may see the

breaking-in guideline every
time you get new brake
linings.
Following break-in, engine speed
and load can be gradually
increased.
Ignition Positions
The vehicle has an electronic
keyless ignition with pushbutton
start. If the pushbutton start is not
working, the vehicle may be near a
strong radio antenna signal causing
interference to the Remote Keyless
Entry (RKE) system. See
Remote
Keyless Entry (RKE) System
Operation 029.
To shift out of P (Park), the ignition
must be on and the brake pedal
must be applied.
Stopping the Engine/OFF (No
Indicator Light) : When the vehicle
is stopped, press ENGINE START/
STOP once to turn the vehicle off.
If the vehicle is in R (Reverse), D
(Drive) or M (Manual Mode), the
vehicle will shift to P (Park), the
ignition will turn off, and Retained
Accessory Power (RAP) will remain
active. See Retained Accessory
Power (RAP) 0181.
If the vehicle is in N (Neutral), the
ignition will return to ACC/
ACCESSORY and display the
message SHIFT TO PARK in the
Driver Information Center (DIC).
When the vehicle is shifted into
P (Park), the ignition will turn off.
{Warning
Turning off the vehicle while
moving may cause loss of power
assist in the brake and steering
systems and disable the airbags.
While driving, only shut the
vehicle off in an emergency.
If the ignition must be shut off in an
emergency: 1. Brake using a firm and steady pressure. Do not pump the
brakes repeatedly. This may
deplete power assist, requiring
increased brake pedal force.
2. Shift the vehicle to N (Neutral). This can be done while the
vehicle is moving. After shifting
to N (Neutral), firmly apply the
brakes and steer the vehicle to
a safe location.
3. Come to a complete stop and shift to P (Park).

178 Driving and Operating
To start the vehicle:1. With the Keyless Access system, the Remote Keyless
Entry (RKE) transmitter must
be in the vehicle. Press
ENGINE START/STOP with the
brake pedal applied. When the
engine begins cranking, let go
of the button. The idle speed
will go down as the engine
warms up. Do not race the
engine immediately after
starting it.
If the RKE transmitter is not in
the vehicle, if there is
interference, or if the RKE
battery is low, a Driver
Information Center (DIC)
message will display. See
Remote Keyless Entry (RKE)
System Operation 029.
Caution
Cranking the engine for long
periods of time, by pressing
ENGINE START/STOP
(Continued)
Caution (Continued)
immediately after cranking has
ended, can overheat and damage
the cranking motor, and drain the
battery. Wait at least 15 seconds
between each try, to let the
cranking motor cool down.
2. If the engine does not start after five to 10 seconds,
especially in very cold weather
(below −18 °C or 0 °F), it could
be flooded with too much
gasoline. Try pushing the
accelerator pedal all the way to
the floor and hold it there, then
press ENGINE START/STOP
for up to a maximum of
15 seconds. Wait at least
15 seconds between each try,
to allow the cranking motor to
cool down. When the engine
starts, let go of the button and
the accelerator. If the vehicle
starts briefly but then stops
again, do the same thing. This
clears the extra gasoline from
the engine. Do not race the engine immediately after
starting it. Operate the engine
and transmission gently until
the oil warms up and lubricates
all moving parts.
Stop/Start System
(Without eAssist)
If equipped, the Stop/Start system
will shut off the engine to help
conserve fuel. It has components
designed for the increased number
of starts.
{Warning
The automatic engine Stop/Start
feature causes the engine to shut
off while the vehicle is still on. Do
not exit the vehicle before shifting
to P (Park). The vehicle may
restart and move unexpectedly.
Always shift to P (Park), and then
turn the ignition off before exiting
the vehicle.
