Towing a trailer.
NOTICE
Do not remove the thermostat in
the engine cooling system as this
may cause the engine to overheat.
The thermostat is designed to con-
trol the flow of coolant to keep the
temperature of the engine within
the specified operating range.
 Do not continue driving with an
overheated engine. See “If your ve-
hicle overheats” on page 343 in
Section 4.
The power meter indicates the instanta-
neous output from the hybrid system in
approximate kilowatts.
While the hybrid system is regenerating
energy, the meter indicates negative.

In the following case, drive directly to
the nearest Toyota dealer.
The yellow warning light comes on
while driving.
Any of the following conditions may oc-
cur, but do not indicate the malfunc-
tion:
The red and yellow warning lights may
stay on for about 60 seconds after the
hybrid system is started. It is normal
if it turns off after a while.
Depressing the brake pedal repeatedly
may turn on the red warning light. It is
normal if the light turns off after a few
seconds.
You may hear a small sound in the
engine compartment after the hybrid
system is started or the brake p edal is
depressed repeatedly. This is a pump
pulsating sound of the brake system,
and it is not a malfunction.
You may hear a motor sound in the
engine compartment when the brake
pedal is depressed with the hybrid sys-
tem turned off.
The brake pedal stroke may be short
when you turn the key to the “START”
position with the brake pedal de-
pressed.
(b) Driver’s Seat Belt Reminder Light and Buzzer
The light and buzzer act as a reminder to
buckle up the driver’s seat belt.
Once the ignition key is turned to “ON”,
the reminder light flashes and buzzer
sounds if the driver ’s seat belt is not fas-
tened. Unless the driver fastens the belt,
the light continues flashing and the buzzer
stops after about 4 to 8 seconds.
(c) Front Passenger ’s Seat Belt Reminder Light
The light acts as a reminder to have the
front passenger buckle up the seat belt.
Once the ignition key is turned to “ON”,
the reminder light flashes if a passenger
sits in the front passenger seat and does
not fasten the seat belt.
If luggage or other load is placed on the
front passenger seat, depending on its
weight, the reminder light may flash. (d) Discharge Warning Light
This light warns that the auxiliary battery
is being discharged.
If it comes on while you are driving, there
is a problem somewhere in the charging
system.
The hybrid system will continue to oper-
ate, however, until the auxiliary battery is
discharged. Turn off the air conditioning,
blower, radio, etc., and drive directly to
the nearest Toyota dealer or repair shop.
(e) Traction Battery Warning Light
This light comes on in the following
cases:
a. The traction battery voltage drops be- cause the transmission is left in the
“N” position.
If you put the transmission in the “P”
position and the light goes off, the system
is working properly. b. The traction battery is discharged.
If the traction battery is discharged and
the warning light comes on along with the
“READY” light, stop your vehicle in a safe
place and contact your Toyota dealer.

“START”—Starting position of hybrid
system (“READY” indicator on). The key
will return to the “ON” position when
released.
For starting tips, see page 325 in Section
3.
“ON”—Hybrid system on and all acces-
sories on.
This is the normal driving position.
“ACC”—Accessories such as the radio
are operational, but the hybrid system
is off.
If you leave the key in the “ACC” or
“LOCK” position and open the driver’s
door, a buzzer will remind you to remove
the key. “LOCK”—Hybrid system is off and the
steering wheel is locked. The key can
be removed at this position only.
You must push in the key to turn it from
“ACC” to the “LOCK” position. The selec-
tor lever must be in the “P” position be-
fore pushing in the key.
Vehicles with engine immobilizer sys-
tem—Once you remove the key, the en-
gine immobilizer system is automatically
set. (See “Engine immobilizer system” on
page 25 in Section 1
−2.)
When starting the hybrid system, the key
may seem stuck at the “LOCK” position.
To free it, first be sure the key is pushed
all the way in, and then rock the steering
wheel slightly while turning the key.
Approximately five hours after the hybrid
system is turned off, you may hear sound
coming from underneath the luggage
compartment for several minutes. This is
normal operation and does not indicate a
malfunction. (See “Leak detection pump”
on page x.)
It is not a malfunction if the needles on
all meters and gauges move slightly when
the ignition key is turned to the “ACC”,
“ON” or “START” position.
NOTICE
Do not leave the key in the “ON”
position if the hybrid system is off.
The auxiliary battery will discharge.

Your transmission has a shift lock system
to minimize the possibility of incorrect op-
eration. This means you can only shift out
of “P” position when the brake pedal is
depressed (with the ignition switch in “ON”
position and the lock release button de-
pressed).

The shift position is also displayed on the
instrument cluster.

(b) Normal driving
1. Start the hybrid system as instructed in “How to start the hybrid system” on
page 326 in Section 3. The transmis-
sion must be in “P”.
2. With your foot holding down the brake pedal, shift the selector lever to “D”.
CAUTION
Never put your foot on the accelera-
tor pedal while shifting.
3. Release the parking brake and brakepedal. Depress the accelerator pedal
slowly for smooth starting. (c) Using engine braking
To use engine braking intentionally, down-
shift the transmission to “B” position and
take your foot off the accelerator pedal.
During high speed driving you may feel
that engine braking is less effective than
that of ordinary vehicle.
Do not continue normal driving with the
transmission in “B” for a long time.
This may cause decreased fuel econo-
my.CAUTION
Be careful when downshifting on a
slippery surface. Abrupt shifting
could cause the vehicle to spin or
skid.
(d) Backing up
1. Bring the vehicle to a complete stop.
2. With the brake pedal held down with your foot, shift the selector lever to the
“R” position.
NOTICE
Never shift into reverse while the ve-
hicle is moving.
(e) Parking
1. Bring the vehicle to a complete stop.
2. With the brake pedal pressed down, fully depress the parking brake pedal
to apply the parking brake securely.
3. With the brake pedal pressed down, shift the selector lever to the “P” posi-
tion.
When turning the hybrid system off, put
the transmission in the “P” position.
CAUTION
Never attempt to move the selector
lever into “P” position under any cir-
cumstances while the vehicle is mov-
ing. Serious mechanical damage and
loss of vehicle control may result.
(f) Good driving practice
CAUTION
Always keep your foot on the brake
pedal while stopped with the hybrid
system on. This prevents the vehicle
from creeping.
