▼Transmission Ranges
The shift position indication in the
instrument cluster illuminates.
Refer to Shift Position Indication on
page 4-40.
Shift the selector lever to the P or N
position to start the engine.
P (Park)
P locks the transmission and prevents
the front wheels from rotating.
WARNING
Always set the selector lever to P
position and set the parking brake:
Only setting the selector lever to the P
position without using the parking
brake to hold the vehicle is dangerous.
If P fails to hold, the vehicle could
move and cause an accident.
CAUTION
 Shifting into P, N or R while the
vehicle is moving can damage your
transmission.
 Shifting into a driving gear or reverse
when the engine is running faster
than idle can damage the
transmission.
R (Reverse)
In position R, the vehicle moves only
backward. You must be at a complete
stop before shifting to or from R,
except under rare circumstances as
explained in Rocking the Vehicle (page
3-53).
NOTE
(With parking sensor system)
When the selector lever is shifted to
the R position with the ignition
switched ON, the parking sensor
system is activated and a beep sound is
heard.
Refer to Parking Sensor System on page
4-231.
N (Neutral)
In N, the wheels and transmission are
not locked. The vehicle will roll freely
even on the slightest incline unless the
parking brake or brakes are on.
WARNING
If the engine is running faster than
idle, do not shift from N or P into a
driving gear:
It's dangerous to shift from N or P into
a driving gear when the engine is
running faster than idle. If this is done,
the vehicle could move suddenly,
causing an accident or serious injury.
Do not shift into N when driving the
vehicle:
Shifting into N while driving is
dangerous. Engine braking cannot be
applied when decelerating which
could lead to an accident or serious
injury.
CAUTION
Do not shift into N when driving the
vehicle. Doing so can cause
transmission damage.
NOTE
Apply the parking brake or depress the
brake pedal before moving the selector
lever from N position to prevent the

Smart Brake Support(SBS)
*
▼Smart Brake Support (SBS)
The SBS is a system designed to detect
target objects using sensors and
cameras equipped on the vehicle, and
to reduce damage in the event of a
collision by operating the brake control
if there is the possibi
lity of your vehicle
colliding with a target object.
One part of the SBS functions when
you are driving forward and the other
part functions when you are driving in
reverse.
Refer to Forward drive detection on
page 4-156.
Refer to Reverse drive detection on
page 4-158.
▼ Forward drive detection
When you are driving forward, the
following functions of the Smart Brake
Support (SBS) operate.
Forward detection function
WARNING
Do not rely completely on the
SBS:
The SBS is only designed to reduce
damage in the event of a collision.
The system may not operate normally
depending on the target object,
weather conditions, or traffic
conditions. Over reliance on the
system leading to the accelerator pedal
or brake pedal being mistakenly
operated could result in an accident.
CAUTION
In the following cases, turn the SBS off
to prevent a mis-operation.
 The vehicle is being towed or towing
another vehicle.
 The vehicle is driven on rough roads
such as in areas where there is grass
and foliage or off-road.
Refer to Stopping the Smart Brake
Support (SBS) System Operation on
page 4-163.
Forward detection function
The forward detection function is
designed to reduce damage in the
event of a collision with target objects
at the front.
The forward detection function detects
target objects (vehicles ahead,
pedestrians, and bicycles) using the
front radar sensor and the Forward
Sensing Camera (FSC). If there is a
possibility of your vehicle colliding with
a target object at the front, you are
notified of possible danger by a
warning sound and a warning
indication on the display.
Furthermore, if the possibility of a
collision increases, the brake control is
performed to reduce damage in the
event of a collision. In addition, when
the driver depresses the brake pedal,
the brakes are applied firmly and
quickly to assist.

(Vehicles with Driver Monitoring
(DM))
If the system determines that the driver
is not paying attention to the road, it
activates the collision warning earlier
than normal.
Operation conditions
The forward detection function
operates when all of the following
conditions are met.
The ignition is switched ON.The SBS is on.(Object is vehicle ahead)
