Quick Reference Guide
Auto Engine Stop/Start
Your vehicle’s gasoline engine will automatically stop and start during vehicle operation as needed to meet driving and battery conditions.
These are some examples that could cause the gasoline engine to automatically start.
In the following cases, however, Auto Engine Stop may not activate.
●When the Integrated Dynamics System is in SPORT+ mode or TRACK mode.●The vehicle momentarily needs additional power for aggressive acceleration, or driving uphill or at high speed.●The climate control system is in heavy use.●The High Voltage battery temperature is high or low.●The High Voltage battery state of charge is low.●The engine coolant temperature is low.●When the door is opened after releasing seatbelt.●When the shift position is in M (Manual) mode.
About Your Vehicle’s Limited Operating Temperature
If the outside temperature is about -4°F (-20°C), some operation might be limited.
The limited operation is listed below:
2 High Voltage Battery (P94)
2 Dual Clutch Transmission (P329)
2 Shifting (P330)
Sounds Unique to th e SPORT HYBRID SH-AWD ® System
When you first start driving this vehicle, you likely will hear some unfamiliar sounds, particular ly when you first turn on the power system,
while driving, and just after parking. Some of these sounds are unique to this ve hicle‘s powertrain, fuel, and climate control systems; others
are similar to sounds generated by conventional automobiles that typically are masked by louder noises absent from a vehicle of this design.
These sounds are not a cause for concern, and you will soon recognize them as normal and thus be able to detect any new or unus ual noise
should one develop.
About a system to cool the High Voltage battery using the climate control system.●The system will not be activated when the defroster is ON.●When the outside temperature is in extreme hot or cold condit ion, the system may not provide sufficient cooling performance to the
High Voltage battery due to the protection of the electric A/C compressor.
●When the system is active, the climate control system may not work sufficiently.

Paddle Shifters (P338)
Paddle shifters allow you to shift gears much like a manual transmission (1st through 9th). This is useful for regenerative bra king.
You cannot shift up or down while in EV mode.
When the transmission is in (D (D-paddle shift mode)The vehicle will go into the sequential mode momentarily, and the gear selection
indicator becomes more prominent.
The sequential mode is automatically canceled and the gear selection indicator
returns to ordinary display un der the following conditions.
•Hold the (+ paddle shifter for a few seconds.
•Once you start traveling at a constant speed.
•The vehicle comes to a complete stop.
•When you change to another Integrated Dynamics System mode.
The sequential mode automatically shifts under following condition
•Accelerator pedal depressed beyond the click.
•Engine speed reaches near the tachometer’s red zone.
•Engine speed reaches idle speed while deceleration.
When the transmission is in M (Manual) modeThe vehicle will go into the sequential m ode, and the gear position indicator goes
off and only the gear selection indicator is displayed.
You can cancel this mode by pressing the button, pulling the
( + paddle
shifter for a few seconds or changing Integrated Dynamics System mode to
QUIET . When the sequential mode is canceled, the display is changed from only
the gear selection indicator to both of th e gear position indicator and the gear
selection indicator.
The transmission automatically shi fts up from 1st to 2nd and does not
automatically shift up between 2nd and 9th gear.D/M

uuSeat Belts uAbout Your Seat Belts
Safe Driving
■Proper use of seat belts
Follow these guidelines for proper use:
• All occupants should sit upright, well back in the seat, and remain in that position
for the duration of the trip. Slouching and leaning reduc e the effectiveness of the
belt and can increase the chance of serious injury in a crash.
• Never place the shoulder part of a lap/shoulder seat belt under your arm or
behind your back. This could cause very serious injuries in a crash.
• Two people should never use the same seat belt. If they do, they could be very
seriously injured in a crash.
• Do not put any accessories on the seat be lts. Devices intended to improve comfort
or reposition the shoulder part of a seat belt can reduce the protective capability
and increase the chance of serious injury in a crash.
The seat belt system includes an indicator on
the instrument panel to remind the driver or a
passenger or both to fasten their seat belts.
If you set the power mode to ON and a seat
belt is not fastened, a beeper will sound and
the indicator will blink. After a few seconds,
the beeper will stop and the indicator will
come on and remain illuminated until the seat
belt is fastened.
The beeper will periodically sound and the
indicator will blink while the vehicle is moving
until the seat belt is fastened.
■Seat Belt Reminder
1About Your Seat Belts
If your passenger moves around and extends the seat
belt, the lockable retractor may activate. If this
happens, release the retractor by unfastening the
seat belt and allow the belt to retract completely.
Then refasten the belt.
1Seat Belt Reminder
The indicator will also co me on if a passenger does
not fasten their seat belt within six seconds after the
power mode is set to ON.
When no one is sitting in th e passenger’s seat, or a
child is riding there, the indicator will not come on
and the beeper will not sound.

uuAirbags uAirbag System Components
Safe Driving
The front, driver’s knee, side, and side
curtain airbags are deployed according to
the direction and severity of impact. Both
side curtain airbags are deployed in a
rollover. The airbag system includes:
aTwo SRS (Supplemental Restraint System)
front airbags. The driver’s airbag is stored
in the center of the steering wheel; the
passenger’s airbag is stored in the
dashboard. Both are marked SRS
AIRBAG.
bDriver’s knee airbag. The knee airbag is
stored under the steering column. It is
marked SRS AIRBAG.
cTwo side airbags, one for the driver and
one for the passenger. The airbags are
stored in the outer edges of the seat-
backs. Both are marked SIDE AIRBAG .
dTwo side curtain airbags, one for each
side of the vehicle. The airbags are stored
in the ceiling, above the side windows.
The front and rear pillars are marked
SIDE CURTAIN AIRBAG.
eAn electronic control unit that, when the
power system is on, continually monitors
information about the various impact
sensors, seat and buckle sensors, rollover
sensor, airbag activators, seat belt
tensioners, and other vehicle
information. During a crash event the
unit can record such information.
fAutomatic seat belt tensioners. In
addition, the driver’s and passenger’s
seat belt buckles incorporate sensors that
detect whether or not the belts are
fastened.
gWeight sensors in the passenger’s seat.
The sensors are used for occupant
classification to activate or deactivate the
passenger’s airbag.
hImpact sensors that can detect a
moderate-to-severe front or side impact.
iAn indicator on the dashboard that alerts
you that the passenger’s front airbag has
been turned off.
jAn indicator on the instrument panel that
alerts you to a possib le problem with your
airbag system or seat belt tensioners.
kA rollover sensor that can detect if your
vehicle is about to roll over and signal the
control unit to deploy both side curtain
airbags.

uuAirbags uFront Airbags (SRS)
Safe DrivingFront airbags are designed to inflate duri ng moderate-to-severe frontal collisions.
When the vehicle decelerates suddenly, the sensors send information to the control
unit which signals one or both front airbags to inflate.
A frontal collision can be either head-on or angled between two vehicles, or when a
vehicle crashes into a stationary object, such as a concrete wall.
While your seat belt restrains your torso, the
front airbag provides supplemental protection
for your head and chest.
The front airbags deflate immediately so that
they won’t interfere with the driver’s visibility
or the ability to steer or operate other
controls.
The total time for inflation and deflation is so fast that most occupants are not
aware that the airbags deployed until th ey see them lying in front of them.
■Operation
■How the Front Airbags Work1How the Front Airbags Work
Although the driver’s a nd passenger’s airbags
normally inflate within a spli t second of each other, it
is possible for only one airbag to deploy. This can
happen if the severity of a collision is at the margin,
or threshold that determines whether or not the
airbags will deploy. In such cases, the seat belt will
provide sufficient protec tion, and the supplemental
protection offered by the airbag would be minimal.
