●Pre-collision braking
The system may not operate in the following situations:
●If a 12-volt battery te rminal has been disc onnected and reconne cted and
then the vehicle has not been dr iven for a certain amount of time
●If the shift lever is in R
●When the VSC OFF indicator is illuminated (only the pre-collision warning
function will be operational)
■Object detection function
The system detects objects based
on their size, profile, motion, etc.
However, an object may not be
detected depending on the sur-
rounding brightness and the motion,
posture, and angle of the detected
object, preventing the system from
operating properly. ( P.255)
The illustration sh ows an image of
detectable objects.
■Cancelation of t he pre-collision
braking
If either of the fo llowing occur while
the pre-collision braking function is
operating, it will be canceled:
●The accelerator pedal is
depressed strongly.
●The steering wheel is turned
sharply or abruptly.
■Conditions under which the
system may operate even if
there is no possibility of a colli-
sion
●In some situations such as the fol-
lowing, the system may determine
that there is a possibility of a fron-
tal collision and operate.
• When passing a detectable object, etc.
• When changing lanes while over-
taking a detectable object, etc.
• When approaching a detectable object in an adjacent lane or on
the roadside, such as when
changing the course of travel or
driving on a winding road
• When rapidly closing on a detect- able object, etc.
• When approaching objects on the roadside, such as detectable
objects, guardrails, utility poles,

Driving
WARNING
●When driving off-road or in rug-
ged terrain, do not drive at
excessive speeds, jump, make
sharp turns, strike objects, etc.
This may cause loss of control
or vehicle rollover causing
death or serious injury. You are
also risking expensive damage
to your vehicle’s suspension
and chassis.
NOTICE
■To prevent the water damage
Take all necessary safety mea-
sures to ensure that water dam-
age to the hybrid battery (traction
battery), hybrid s ystem or other
components does not occur.
●Water entering the engine com-
partment may cause severe
damage to the hybrid system.
Water entering the interior may
cause the hybrid battery (trac-
tion battery) stowed under the
rear seats to short circuit.
●Water entering t he hybrid trans-
mission will cause deterioration
in transmission quality. The
malfunction indicator may come
on, and the vehicle may not be
drivable.
●Water can wash the grease
from wheel bearings, causing
rusting and premature failure,
and may also enter the hybrid
transaxle case, reducing the
gear oil’s lubricating qualities.
■When you drive through
water
If driving through water, such as
when crossing shallow streams,
first check the depth of the water
and the bottom of the riverbed for
firmness. Drive slowly and avoid
deep water.
■Inspection after off-road driv-
ing
●Sand and mud that has accu-
mulated around brake discs
may affect braking efficiency
and may damage brake system
components.
●Always perform a maintenance
inspection after each day of off-
road driving that has taken you
through rough terrain, sand,
mud, or water. For scheduled
maintenance information, refer
to the “Scheduled Maintenance
Guide” or “Owner’s Manual
Supplement”.
