mation display. At extremely low tem-
peratures, the information display
monitor may respond slowly, and display
changes may be delayed.
For example, there is a lag between the
driver’s shifting and the new gear num-
ber appearing on the display. This lag
could cause the driver to downshift
again, causing rapid and excessive
engine braking and possibly an accident
resulting in death or injury.
NOTICE
QTo prevent damage to the engine and
its components
ODo not let the indicator needle of the
tachometer enter the red zone, which
indicates the maximum engine speed.

WARNING
QWhen taking a nap in the vehicle
Always turn the hybrid system off. Oth-
erwise, if you accidentally move the shift
lever or depress the accelerator pedal,
this could cause an accident or fire due
to hybrid system overheating. Addition-
ally, if the vehicle is parked in a poorly
ventilated area, exhaust gases may col-
lect and enter the vehicle, leading to
death or a serious health hazard.
QWhen braking
OWhen the brakes are wet, drive more
cautiously.
Braking distance increases when the
brakes are wet, and this may cause
one side of the vehicle to brake differ-
ently than the other side. Also, the
parking brake may not securely hold
the vehicle.
OIf the electronically controlled brake
system does not operate, do not follow
other vehicles closely and avoid hills or
sharp turns that require braking.
In this case, braking is still possible, but
the brake pedal should be depressed
more firmly than usual. Also, the brak-
ing distance will in crease. Have your
brakes fixed immediately.
OThe brake system consists of 2 or
more individual hydraulic systems; if
one of the systems fails, the other(s)
will still operate. In this case, the brake
pedal should be depressed more
firmly than usual and the braking dis-
tance will increase. Have your brakes
fixed immediately.
NOTICE
QWhen driving the vehicle
ODo not depress the accelerator and
brake pedals at the same time while
driving, as this may restrain the hybrid
system output.
ODo not use the accelerator pedal or
depress the accelerator and brake
pedals at the same time to hold the
vehicle on a hill.
QAvoiding damage to vehicle parts
ODo not turn the steering wheel fully in
either direction and hold it there for an
extended period of time.
Doing so may damage the power
steering motor.
OWhen driving over bumps in the road,
drive as slowly as possible to avoid
damaging the wheels, underside of the
vehicle, etc.
QIf you get a flat tire while driving
A flat or damaged tire may cause the fol-
lowing situations. Hold the steering
wheel firmly and gradually depress the
brake pedal to slow down the vehicle.
OIt may be difficult to control your vehi-
cle.
OThe vehicle will make abnormal
sounds or vibrations.
OThe vehicle will lean abnormally.

tire ( P.379)
QWhen encountering flooded roads
Do not drive on a road that has flooded
after heavy rain etc. Doing so may cause
the following serious damage to the vehi-
cle:
OEngine stalling
OShort in electrical components
OEngine damage caused by water
immersion
In the event that you drive on a flooded
