Driving *3
: C =Available cargo and luggage load
In this condition, if 3 more passengers with
the combined weight of D lb. (kg) get on,
the available cargo and luggage load will
be reduced E lb. (kg) as follows:
C lb. (kg) - D *4
lb. (kg) = E *5
lb. (kg)*4
: D =Additional weight of people *5
: E =Available cargo and luggage load
As shown in the example above, if the
number of occupants increases, the
cargo and luggage load will be
reduced by an amount that equals the
increased weight due to the additional
occupants. In other words, if an
increase in the number of occupants
causes an excess of the total load
capacity (combined weight of occu-
pants plus cargo and luggage load),
you must reduce the cargo and lug-
gage on your vehicle. WARNING■
Things that must not be carried in the
trunk
The following things may cause a fire if
loaded in the trunk:
●
Receptacles containing gasoline
●
Aerosol cans
■
Storage precautions
Observe the following precautions.
Failure to do so may prevent the pedals
from being depressed properly, may
block the driver’s vision, or may result in
items hitting the driver or passengers,
possibly causing an accident.
●
Stow cargo and luggage in the trunk
whenever possible. ●
Do not place cargo or luggage in or on
the following locations.
• At the feet of the driver
• On the front passenger or rear seats
(when stacking items)
• On the package tray
• On the instrument panel
•On the dashboard
• In front of the Center Display ●
Secure all items in the occupant com-
partment. ■
Capacity and distribution ●
Do not exceed the maximum axle
weight rating or the total vehicle
weight rating. ●
Even if the total load of occupant’s
weight and the cargo load is less than
the total load capacity, do not apply the
load unevenly. Improper loading may
cause deterioration of steering or
braking control which may cause
death or serious injury.

position to turn the high beams off.
2 Pull the lever toward you and
release it to flash the high beams
once.You can flash the high beams with the
headlights on or off.
AFS (Adaptive Front-lighting System)
secures excellent visibility at intersec-
tions and on curves by automatically
adjusting the direction of the light axis
of the headlights according to vehicle
speed and the degree of the tire’s angle
as controlled by steering input. AFS operates at speed s of approximately
6 mph (10 km/h) or higher.
■
Customization
Some functions can be customized.
( → P.481)
 When the steering wheel or turn
signal lever is operated while the
headlights are on (low beam), a cor-
nering light will turn on and light up
the direction of movement of the
vehicle. The cornering lights are
designed to ensure excellent visibil-
ity when making a turn at an inter-
section. However, when vehicle speed is approxi-
mately 22 mph (35 km/h) or higher, the
cornering lights will not turn on.
 When the shift position is in R while the headlights are on (low beam),
both cornering lights will turn on.
This is designed to enhance visibility
when parking. ■
Cornering lights
When the cornering lights are on for more
than 30 minutes, they will turn off automati-
cally.

Active steering assist
If the system determines that the possi-
bility of a collision with an object, such
as a guardrail, or pedestrian is high,
even though the brakes are applied,
and that the collision may be avoidable
through steering control, the system
will steer the vehicle automatically to
help avoid the collision or help reduce
the impact of the collision. ■
Pre-collision seat belts (front seat
only)
If the system determines that the possi-
bility of a frontal collision is high, the
system will retract the seat belts. Addi-
tionally, the system may retract the seat
belts if the brakes are applied suddenly
or control of the vehicle is lost. ■
Pre-collision seatbacks (front pas-
senger’s seat / power rear seat [if
equipped])
If the system determines that the possi-
bility of a frontal collision is high, it may
move the seatbacks of the front pas-
senger’s seat and power rear seats to
the upright position automatically, if
reclined. If a seat is being ad justed, it may not be
moved by the pre-collision seat function.
■
Suspension control
When the system determines that the
possibility of a frontal collision is high,
the Adaptive Variable Suspension Sys-
tem ( → P.303) will control the damp-
ing force of the shock absorbers to
help maintain an appropriate vehicle
posture. ■
Steering control
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.303) will
control the turning angle of the front
and rear wheels and effort necessary
to turn the steering wheel to help
enhance steering responsiveness. WARNING■
Limitations of the pre-collision system ●
The driver is solely responsible for safe
driving. Always drive safely, taking
care to observe your surroundings.
Do not use the pre-collision system
instead of normal braking operations
under any circumstances. This system
will not prevent collisions or lessen col-
lision damage or injury in every situa-
tion. Do not overly rely on this system.
Failure to do so may lead to an acci-
dent, resulting in death or serious
injury. ●
Although this system is designed to
help avoid a collision or help reduce
the impact of the collision, its effective-
ness may change according to various
conditions, therefore the system may
not always be able to achieve the same
level of performance.
Read the following conditions care-
fully. Do not overly rely on this system
and always drive carefully.
• Conditions under which the system
may operate even if there is no possi-
bility of a collision: → P.214
• Conditions under which the system
may not operate properly: → P.216
●
Do not attempt to test the operation of
the pre-collision system yourself, as the
system may not operate properly, pos-
sibly leading to an accident.

Driving WARNING■
Pre-collision braking●
When the pre-collision braking func-
tion is operating, a large amount of
braking force will be applied.●
If the vehicle is stopped by the opera-
tion of the pre-collision braking func-
tion, the pre-collision braking function
operation will be canceled after
approximately 2 seco nds. Depress the
brake pedal as necessary.●
The pre-collision braking function may
not operate if certain operations are
performed by the driver. If the acceler-
ator pedal is being depressed strongly
or the steering wheel is being turned,
the system may determine that the
driver is taking evasive action and may
prevent the pre-collision braking func-
tion from operating.●
In some situations, while the pre-colli-
sion braking function is operating,
operation of the function may be can-
celed if the accelerator pedal is
depressed strongly or the steering
wheel is turned and the system deter-
mines that the driver is taking evasive
action.
●
If the brake pedal is being depressed,
the system may determine that the
driver is taking evasive action and pos-
sibly delay the operation timing of the
pre-collision braking function.
■
Active steering assist●
The steering wheel may turn automati-
cally when active steering assist is
operating.
●
As active steering assist operation will
be canceled when the system deter-
mines that a collision has been
avoided, operate the steering wheel as
necessary. ●
In the following situations, the system
may determine that th e driver is taking
evasive action. In this case, the active
steering assist may not operate or may
be canceled.
• If the accelerator pedal is being
depressed strongly or the steering
wheel is being operat ed. In this case
the system may determine that the
driver is taking evasive action and the
pre-collision braking may not operate.
• In some situations, while the active
steering assist is operating, operation
of the function may be canceled if the
accelerator pedal is depressed
strongly or the steering wheel is turned
and the system determines that the
driver is taking evasive action.
• When the active steering assist is
operating, if the stee ring wheel is held
firmly or is operated in the opposite
direction to that which the system is
generating torque, the function may be
canceled.
• If the brake pedal is depressed, the sys-
tem may determine that the driver is
taking evasive action and the active
steering assist operation may be
delayed.
■
Pre-collision seat belts with comfort
function
If the pre-collision se at belts have oper-
ated and the seat belts are locked in a
retracted position, immediately stop the
vehicle in a safe place, release and
retract the seat belts to unlock them and
then fasten them again.
Also, if a seat belt ca n be loosened, it can
be unlocked by slightly retracting it with-
out releasing it.
■
When to disable the pre-collision sys-
tem
In the following situations, disable the
system, as it may not operate properly,
possibly leading to an accident resulting
in death or serious injury:
●
When the vehicle is being towed
