WARNING
■The information display at
low temperatures
Allow the interior of the vehicle to
warm up before u sing the liquid
crystal informat ion display. At
extremely low temperatures, 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 number appearing
on the display. This lag could
cause the driver to downshift
again, causing rapid and exces-
sive engine braking and possibly

WARNING
●Do not attach adhesive discs to
the windshield or windows. Do
not place containers such as air
fresheners on the instrument
panel or dashboard. Adhesive
discs or containers may act as
lenses, causing a fire in the
vehicle.
●Do not leave a door or window
open if the curved glass is
coated with a metallized film
such as a silver-colored one.
Reflected sunlight may cause
the glass to act as a lens, caus-
ing a fire.
●Always apply the parking brake,
shift the shift lever to P, stop the
hybrid system and lock the vehi-
cle.Do not leave the vehicle
unattended while the “READY”
indicator is illuminated.If the
vehicle is parked with the shift
lever in P but the parking brake
is not set, the vehicle may start
to move, possibly leading to an
accident.
●Do not touch the exhaust pipes
while the “READY” indicator is
illuminated or immediately after
turning the hybrid system
off.Doing so may cause burns.
■When taking a nap in the vehi-
cle
Always turn the hybrid system off.
Otherwise, if you accidentally
move the shift lever or depress
the accelerator pedal, this could
cause an accident or fire due to
hybrid system overheating. Addi-
tionally, if the vehicle is parked in
a poorly ventilated area, exhaust
gases may collect and enter the
vehicle, leading to death or a seri-
ous health hazard.
■When braking
●When the brakes are wet, drive
more cautiously.Braking dis-
tance increases when the
brakes are wet, and this may
cause one side of the vehicle to
brake differently than the other
side. Also, the parking brake
may not securely hold the vehi-
cle.
●If 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 braking dis-
tance will increase. Have your
brakes fixed immediately.
●The brake system consists of 2
or more individual hydraulic sys-
tems; 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 brak-
ing distance will increase. Have
your brakes fixed immediately.
■If the vehicle becomes stuck
(AWD models)
Do not spin the wheels exces-
sively when any of the tires is up
in the air, or the vehicle is stuck in
sand, mud, etc. This may damage
the driveline components or pro-
pel the vehicle forward or back-
ward, causing an accident.
NOTICE
■When driving the vehicle
●Do not depress the accelerator
and brake pedals at the same
time during driving, as this may
restrain the hybrid system out-
put.

overheat and result in
reduced braking efficiency.
 Due to the added load of the
trailer, your vehicle’s engine
may overheat on hot days (at
temperatures over 85°F
[30°C]) when driving up a long
or steep grade. If the engine
coolant temperature gauge
indicates overheating, imme-
diately turn off the air condi-
tioning (if in use), pull your
vehicle off the road and stop
in a safe spot. ( P.484)
 Always place wheel blocks
under both the vehicle’s and
the trailer’s wheels when
parking. Put the transmission
in P and apply the parking
brake. Avoid parking on a
slope, but if unavoidable, do
so only after performing the
following:
1 Apply the brakes and keep
them applied.
2 Have someone place wheel
blocks under both the vehi-
cle’s and trailer’s wheels.
3 When the wheel blocks are in
place, release the brakes
slowly until the blocks absorb
the load.
4 Shift into P and apply the
parking brake.
5 Turn off the hybrid system.
 When restarting after parking
on a slope: 1
With the transmission in P,
start the hybrid system. Be
sure to keep the brake pedal
depressed.
2 Shift into a forward gear. If
reversing, shift into R.
3 If the parking brake is in man-
ual mode, release the park-
ing brake. ( P.217)
4 Release the brake pedal, and
slowly pull or back away from
the wheel blocks. Stop and
apply the brakes.
5 Have someone retrieve the
blocks.
