NOTEThe rated voltage of each USB
terminal is 5 V/2.1 A (total 4.2 A). For
details about the maximum rated
power, refer to "How to Use the USB
Power Supply" P217. Before
connecting a device, be sure to read
the instruction manual of the device
and check whether or not this specifi-
cation of the output is supported by the
device. If a device that requires power
exceeding the maximum rating is
connected, power supply or charging
may not be possible. Even if charging
could be completed, the time required
for charging may be longer than when
the genuine charger for that device is
used.
 Depending on the device, charging
may be possible only when a special
If the plug on your electric appli-
ance is either too loose or too
tight for the accessory power
outlet, this can result in a poor
contact or cause the plug to get
stuck. Only use plugs that fit
properly. Use of an electric appliance in the
accessory power outlet for a long
period of time while the engine is
not running can cause battery
discharge. Before driving your vehicle, make
sure that the plug and the cord on
your electrical appliance will not
interfere with your shifting gears
and operating the accelerator and
brake pedals. If they do, do not
use the electrical appliance while
driving.
CAUTION
 The specification of a USB
terminal that can be used is the A-
type. If a different specification of
terminal is connected, power
supply or charging may not be
possible, or the device may
malfunction. There is a risk that a connected
device may malfunction or data
may be damaged. The connection
of a device shall be performed at
your responsibility. To avoid an electric shock or a
malfunction, observe the
following precautions.
- Do not connect a USB hub.- Do not insert any metal or

7-2. State Emission Testing (U.S. Only)California and a number of federal states

have Inspection/Maintenance programs
to inspect your vehicle’s emission control
system. If your vehicle does not pass this
test, some states may deny renewal of
your vehicle’s registration.
Your vehicle is equipped with a computer
that monitors the performance of the
engine’s emission control system. Certi-
fied emission inspectors will inspect the
On-Board Diagnostic (OBDII) system as
part of the state emission inspection
process. The OBDII system is designed to
detect engine and transmission problems
that might cause the vehicle emissions to
exceed allowable limits. OBDII inspec-
tions apply to all 1996 model year and
newer passenger cars and trucks. Over
30 states plus the District of Columbia
Immediately put fuel in the tank
whenever the low fuel warning
light illuminates. Engine misfires
as a result of an empty tank could
cause damage to the engine.
Continuing to operate your
vehicle at an extremely low fuel
level may result in a reduction of
engine performance.

Automatic Transmission
237
Starting and Operating7
– CONTINUED –
▼P (Park)
This position is for parking the vehicle and
starting the engine. In this position, the
transmission is mechanically locked to
prevent the vehicle from rolling freely.
When you park the vehicle, first apply the
parking brake, then shift into the “P” posi-
tion. Do not hold the vehicle with only the
mechanical friction of the transmission.
To shift the select lever from the “P” to any
other position, you should depress the
brake pedal fully then move the select
lever. This prevents the vehicle from
lurching when it is started.
▼ R (Reverse)
This position is for backing the vehicle. To
shift from the “N” to “R” position, stop the
vehicle completely th en move the lever to
the “R” position.
▼ N (Neutral)
This position is for restarting a stalled
engine. In this position, the transmission is
neutral, meaning that the wheels and
transmission are not locked. Therefore,
the vehicle will roll freely, even on the
slightest incline unless the parking brake
or foot brake is applied. ▼
D (Drive)
This position is for normal driving. The
transmission shifts automatically into a
suitable gear according to the vehicle
speed and the acceleration you require.
Also, while driving up and down a hill, the
transmission assists and controls the
driving performance and engine braking
while corresponding to the road grade.
When more acceleration is required in “D”
position, depress the accelerator pedal
fully to the floor and hold that position. The
transmission will auto matically downshift.
When you release the pedal, the transmis-
sion will return to the original gear posi-
tion.
To use the manual mode, move the lever
from this position into the manual gate.
If one of the shift paddles behind the
steering wheel is operated while driving in
the “D” position, the transmission will
temporarily switch to the manual mode. In
this mode, you can shift into any gear position using the shift paddles. For

details about the manual mode, refer to
"Selection of Manual Mode" P239.
Once the vehicle speed stabilizes, the
transmission will switch from the manual
mode back to the “D” position for normal
driving.
▽ While climbing a grade
When driving up a hill, undesired upshift is
prevented from taking place when the
accelerator is releas ed. This minimizes
the chance of subsequent downshifting to
a lower gear when accelerating again.
This prevents repeated upshifting and
downshifting resulting in a smoother oper-
ation of the vehicle.
NOTEThe transmission may downshift,
depending on the way the accelerator
pedal is depressed to accelerate the
vehicle again.■ Adaptive ControlIn order to realize smoother driving while
driving in “D” position, an appropriate gear
is automatically selected by limiting
upshifting and performing downshifting
operations according to driver operations
and driving conditions.
WARNING
Do not drive the vehicle with the
select lever in the “N” (neutral)
position. Engine braking has no
effect in this co ndition and the risk
of an accident is consequently
increased.

Vehicle Stability Control (VSC)/TRAC System
247
Starting and Operating7
– CONTINUED –
7-13. Vehicle Stability Control (VSC)/TRAC System■Vehicle Stability Control
(VSC) SystemIn the event of wheelspin and/or skidding
on a slippery road surface and/or during
cornering and/or an evasive maneuver,
the Vehicle Stability Control (VSC) system
adjusts the engine’s output and the
wheels’ respective braking forces to help
maintain traction and directional control.
The skid suppression function is designed
to help maintain directional stability by
suppressing the wheels’ tendency to slide
sideways during steering operations. Acti-
vation of this function is indicated by
flashing of the Vehicle Stability Control
(VSC) operation indicator light.NOTE In the following circumstances, the
vehicle may be less stable than it feels
to the driver. The Vehicle Stability
Control (VSC) system may therefore
operate. Such operation does not indi-
cate a system malfunction. - On gravel-covered or rutted
roads
- On unfinished roads
- When the vehicle is fitted with
snow tires or winter tires 
Activation of the Vehicle Stability
Control (VSC) system will cause opera-
tion of the steering wheel to feel
slightly different compared to that for
normal conditions.
 It is always important to reduce
speed when approaching a corner,
even if the vehicle is equipped with
Vehicle Stability Control (VSC) system.
 Always turn off the engine before
replacing a tire as failure to do so may
render the Vehicle Stability Control
(VSC) system unable to operate
correctly.
■ TRAC SystemThe TRAC system is designed to prevent
spinning of the driving wheels on slippery
road surfaces, thereby helping to maintain
traction and directional control. Activation
of this function is indicated by flashing of
the Vehicle Stability Control (VSC) opera-
tion indicator light. The TRAC system is
also equipped with the brake LSD func-
tion.
WARNING
 Directional control and power
may not be achievable while
driving on slippery road surfaces,
even if the TRAC system is oper-
ating. Do not drive the vehicle in
conditions where stability and
power may be lost. Always use the utmost care in
driving – overconfidence
because you are driving with a
Vehicle Stability Control (VSC)
system and TRAC system
equipped vehicle could easily
lead to a serious accident.
CAUTION
 Even if your vehicle is equipped
with Vehicle Stability Control
(VSC) system and TRAC system,
winter tires should be used when
driving on snow-covered or icy
roads; in addition, vehicle speed
should be reduced considerably.
Simply having a Vehicle Stability
Control (VSC) system and TRAC
system does not guarantee that
the vehicle will be able to avoid
accidents in any situation.

BSD/RCTA (If Equipped)
2687-20. BSD/RCTA (If Equipped)The BSD/RCTA consists of rear corner
radars with Blind Spot Detection and Rear
Cross Traffic Alert.
These functions of BSD/RCTA are the
systems that detect objects and vehicles
to the rear and draw attention to the driver
when changing a lane or when driving in
reverse.
■ System FeaturesBSD/RCTA consists of the following func-
tions.
To detect a vehicle in a blind spot on an
adjacent lane or a vehicle approaching at
high speed while driving the vehicle (Blind
Spot Detection)
 To detect a vehicle approaching from
the right or left while reversing the vehicle
(Rear Cross Traffic Alert) The system uses radar sensors for the

following features.
NOTEThe BSD/RCTA radar sensor has been
certified by the radio wave related laws
of the U.S. and other FCC compliant
countries, Canada and Mexico. When
driving in other countries, certifica-
tion of the country where the vehicle is

WARNING
The driver is responsible for driving
safely. Always be sure to check the
surroundings with your eyes when
changing lanes or reversing the
vehicle.
The system is designed to assist
the driver in changing lanes or
reversing safely by monitoring the
rear and side areas of the vehicle.
However, you cannot rely on this
system alone in assuring the safety
during a lane change or reversing.
Overconfidence in this system
could result in an accident and lead
to serious injury or death. Since the
system operation has various lim-
itations, the flashing or illumination
of the BSD/RCTA approach indica-
tor light may be delayed or it may
