Vehicle status information and indicators
HIGHLANDER HV_U• 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
Small spots or light spots may
appear on the display. This phenom-
enon is characteristi c of liquid crys-
tal displays, and there is no problem
continuing to use the display.
■Customization
The meters can be customized on of the multi-information display.
(  P.99, 109)
■Display items
 Odometer
Displays the total distance the vehi-
cle has been driven.
 Trip meter A/trip meter B
Displays the distance the vehicle
has been driven since the meter
was last reset. Trip meters A and B
can be used to record and display
different distances independently.
■Changing the display
Each time the “ODO TRIP”
switch is pressed, the displayed
item will be changed. When the
trip meter is displayed, pressing
and holding the switch will reset
the trip meter.
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 i ndicator needle
of the tachomete r 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.

WARNING
●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 unat-
tended while the “READY” indi-
cator 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 a re wet, drive
more cautiously.
Braking distance 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
vehicle.
●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 while driving, as this may
restrain the hybrid system out-
put.
●Do not use the accelerator
pedal or depress the accelera-
tor and brake pedals at the
same time to hold the vehicle on
a hill.

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.504)
 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.224)
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.
