Vehicle status information and indicators
■Engine speed
On hybrid electric vehicles, engine
speed is precisely controlled in
order to help improve fuel efficiency
and reduce exhaust emissions etc.
There are times when the engine
speed that is displayed may differ
even when vehicle operation and
driving conditions are the same.
■Outside temperature display
●In the following si tuations, the cor-
rect outside tempe rature may not
be displayed, or the display may
take longer than normal to
change:
• When stopped, or driving at low
speeds (less than 12 mph [20
km/h])
• When the outside temperature
has changed suddenly (at the
entrance/exit of a garage, tunnel,
etc.)
●When “--” or “E” is displayed, the
system may be malfunctioning.
Take your vehicle to your Toyota
dealer.
■Liquid crystal display
 P. 9 1
■Customization
The gauges and meters can be cus-
tomized in of the multi-informa-
tion display. ( P.463)
■Changing the display
Press the display change button
until the desired item is dis-
played.
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
an accident resulting in death or
injury.
NOTICE
■To prevent damage to the
engine and its components
●Do not let the indicator needle
of the tachometer enter the red
zone, which indicates the maxi-
mum engine speed.
●The engine may be overheating
if the engine coolant tempera-
ture gauge is in the red zone
(H). In this case, immediately
stop the vehicle in a safe place,
and check the engine after it
has cooled completely.

1724-1. Before driving
considerable distance. After
passing a vehicle, do not for-
get the length of your trailer,
and be sure you have plenty
of room before changing
lanes.
 To maintain engine braking
efficiency and charging sys-
tem performance when using
engine braking, do not put the
transmission in D. If in the S
mode, the hybrid transmission
shift range position must be in
5 or lower.( P.181)
 Instability happens more fre-
quently when descending
steep or long downhill grades.
Before descending, slow
down and downshift. Do not
make sudden downshifts
while descending steep or
long downhill grades.
 Avoid holding the brake pedal
down too long or applying the
brakes too frequently. This
could cause the brakes to
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.438)
 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 shift lever 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.186)
4 Release the brake pedal, and
slowly pull or back away from
the wheel blocks. Stop and
apply the brakes.

WARNING
The engine compartment contains
many mechanisms and fluids that
may move suddenly, become hot,
or become electrically energized.
To avoid death or serious injury,
observe the following precautions.
■When working on the engine
compartment
●Keep hands, clothing and tools
away from the moving fans.
●Be careful not to touch the
engine, power control unit, radi-
ator, exhaust manifold, etc. right
after driving as they may be hot.
Oil and other fluids may also be
hot.
ItemsParts and tools●Make sure that the “ACCES-
SORY” or “IGNITION ON” on
the multi-information display
and the “READY” indicator are
both off.
●Do not leave anything that may
burn easily, such as paper and
rags, in the engine compart-
ment.
●Do not smoke, cause sparks or
expose an open flame to fuel or
the 12-volt battery. Fuel and
12-volt battery fumes are flam-
mable.
●Be extremely cautious when
working on the 12-volt battery. It
contains poisonous and corro-
sive sulfuric acid.
■When working near the elec-
tric cooling fans or radiator
grille
Be sure the power switch is OFF.
With the power switch in ON, the
electric cooling fans may auto-
matically start to r un if the air con-
ditioning is on an d/or the coolant
temperature is high. ( P.353)
■Safety glasses
Wear safety glasses to prevent
flying or falling material, fluid
spray, etc. from getting in your
eyes.
NOTICE
■If you remove the air cleaner
filter
Driving with the air cleaner filter
removed may cause excessive
engine wear due to dirt in the air.
