1324-2. Driving procedures
Changing the shift range allows
restriction of the highest gear, prevent-
ing unnecessary upshifting and
enabling the level of engine braking
force to be selected.
1Upshifting
2 Downshifting
8-speed models: The se lected shift range,
from D1 to D8, will be displayed on the
meter.
6-speed models: The selected shift range,
from D1 to D6, will be displayed on the
meter.
To return to normal D position driving, the
“+” paddle shift switch must be held down
for a period of time.
A lower shift range will provide greater
engine braking forces than a higher shift
range.
■Automatic deactivation of shift range
selection in the D position
Shift range selection in the D position will
be deactivated in the following situations:
●When the vehicle comes to a stop
●If the accelerator pe dal is depressed for
more than a certai n period of time
●When the shift lever is shifted to a posi-
tion other than D
■Downshifting restriction warning
buzzer
To help ensure safety and driving perfor-
mance, downshifting operation may some-
times be restricted. In some circumstances,
downshifting may not be possible even
when the paddle shift switch is operated. (A
buzzer will sound twice.)
To enter M mode, shift the shift lever to
M. Gears can then be selected by
operating the shift lever or paddle shift
switches, allowing you to drive in the
gear of your choosing.

When in the M position, the gear will
not change unless the shift lever or
paddle shift switch es are operated.
However, even when in the M position,
the gears will be automatically
changed in the following situation:
 When vehicle speed drops (down-
shift only).
 When a gear change is necessary to
protect the engine or automatic
transmission when the engine cool-
ant temperature or automatic trans-
mission fluid temperature is low, or
other reasons.
In the following situations, the gear will
not shift even if the shift lever or paddle
shift switches are operated.
 “Slippery Road. Cannot Shift to
Lower Gear.” is displayed on the
multi-information display.
 The vehicle speed is low (upshift
only).

ASC (Active Sound Con-
trol)*
The ASC system is an electronic
sound system that generates
engine sound, conveying the
kinetic situations of the vehicle’s
acceleration and deceleration to
the driver through the speakers
inside the instrument panel.
The vehicle’s response to the
driver’s acceleration behavior and
shift operations are also conveyed
in sound.
When sport mode is selected, the
sound conveyed to the driver will be
louder.

1564-5. Using the driving support systems
■Pre-collision warning
When the system determines that the
possibility of a frontal collision is high, a
buzzer will sound and a warning mes-
sage will be displayed on the
multi-information display to urge the
driver to take evasive action.
■Pre-collision brake assist
When the system determines that the
possibility of a frontal collision is high,
the system applies greater braking
force in relation to how strongly the
brake pedal is depressed.
■Pre-collision braking
When the system determines that the
possibility of a frontal collision is high,
the system warns the driver. If the sys-
tem determines that the possibility of a
frontal collision is extremely high, the
brakes are automatically applied to
help avoid the collision or reduce the
collision speed.
■Suspension control (if equipped)
When the system determines that the
possibility of a frontal collision is high,
the Adaptive Variable Suspension Sys-
tem ( P.194) will control the damping
force of the shock absorbers to help
maintain an appropriate vehicle pos-
ture.
■Steering control (if equipped)
When the system determines that the
possibility of a frontal collision is high
and the driver is op erating the steering
wheel, the LDH system ( P.195) will
control the turning angle of the front
PCS (Pre-Collision System)
The pre-collision system uses a
radar sensor and camera sensor to
detect vehicles and pedestrians in
front of your vehicle. When the sys-
tem determines that the possibility
of a frontal collision with a vehicle
or pedestrian is high, a warning
operates to urge the driver to take
evasive action and the potential
brake pressure is increased to help
the driver avoid the collision. If the
system determines that the possi-
bility of a frontal collision with a
vehicle or pedestrian is extremely
high, the brakes are automatically
applied to help avoid the collision or
help reduce the impact of the colli-
sion.
The pre-collision system can be dis-
abled/enabled and the warning tim-
ing can be changed. ( P.158)

■Lane departure alert function
When the system determines that the
vehicle might depart from its lane, a
warning is displayed on the multi-infor-
mation display, and either the warning
buzzer sounds or the steering wheel
vibrates to alert the driver.
When the warning buzzer sounds or the
steering wheel vibrates, check the sur-
rounding road situation and carefully oper-
ate the steering wheel to move the vehicle
back to the center of the lane.
■Steering control function
When the system determines that the
vehicle might depart from its lane, the
system provides assistance as neces-
sary by operating the steering wheel in
small amounts for a short period of
time to keep the vehicle in its lane.
If the system detects that the steering
wheel has not been operated for a fixed
amount of time or the steering wheel is not
being firmly gripped, a warning is displayed
on the multi-informat ion display and the
function is temporarily canceled.
LDA (Lane Departure Alert
with steering control)
When driving on highways and
freeways with white (yellow) lines,
this function alerts the driver when
the vehicle might depart from its
lane and provides assistance by
operating the steering wheel to
keep the vehicle in its lane.
The LDA system recognizes visible
white (yellow) lines with the camera
sensor on the upper portion of the
front windshield.
