Shift position indicator
The position of the frame on the shift position indicator changes in
accordance with the current shift position.
When any shift position other than D or B is selected, the arrow toward
B and B position indicator disappear from the shift position indicator.
When selecting the shift position, make sure that the shift position has
been changed to the desired position by checking the shift position indica-
tor provided on the instrument cluster.
■Shift position purpose
*:For good fuel economy and noise reduction, the D position should usu-
ally be used.
Shift positionFunction
PParking the vehicle/starting the hybrid system
RReversing
NNeutral
DNormal driving*
BApplying moderate engine braking when driving

When driving
■About engine braking
When shift position B is selected, releasing the accelerator pedal will apply
engine braking.
●When the vehicle is driven at high speeds, compared to ordinary gaso-
line-fueled vehicles, the engine braking deceleration is felt less than that
of other vehicles.
●The vehicle can be accelerated even when shift position B is selected.
If the vehicle is driven continuously in the B position, fuel efficiency will
become low. Usually, shift the shift position to D.
■When driving with cruise control or radar cruise control activated
Even if switching the driving mode to power mode with the intent of enabling
engine braking, engine braking will not activate because cruise control or
radar cruise control will not be canceled.
■When canceling Eco drive mode/power mode
●Press the switch again. Also, power mode will be canceled automatically
when the “POWER” switch is turned off. However, Eco drive mode will
not be canceled automatically until the switch is pressed, even if the
“POWER” switch is turned off.
●When in Eco drive mode, if the power mode switch is pressed or the
operation is reversed, the mode will switch to that of the last switch to be
pressed.

CAUTION
■When driving on slippery road surfaces
Do not accelerate or shift the shift position suddenly.
Sudden changes in engine braking may cause the vehicle to spin or skid,
resulting in an accident.
■For the shift lever
Do not remove the shift lever knob or use anything but a genuine Toyota shift
lever knob. Also, do not hang anything on the shift lever.
Doing so could prevent the shift lever from returning to position, causing
unexpected accidents to occur when the vehicle is in motion.
■P position switch
Do not press the P position switch while the vehicle is moving.
If the P position switch is pressed when driving at very low speeds (for
example, directly before stopping the vehicle), the vehicle may stop sud-
denly when the shift position switches to P, which could lead to an accident.

The engine may be overheating if the high coolant temperature warning light
comes on or flashes. In this case, immediately stop the vehicle in a safe
place, and check the engine after it has cooled completely. (→P. 6 0 3 )
Do not place anything or attach a sticker
in front of the instrument cluster. The item
may obscure or obstruct the display, or
could reflect off the display, possibly
causing an accident.

tions.
*2: If the gasoline engine is operated (for example when driving at high
speeds or using the heater), the EV indicator may turn off even if the bar
is in the EV driving area. (→P. 4 0 )

■Display settings can be changed when
The vehicle speed is less than approximately 5 mph (8 km/h).
■Engine speed
On hybrid 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 oper-
ation and driving conditions are the same.
■When the 12-volt battery is disconnected
The following data will be reset.
●Average fuel consumption
●Distance to empty

■Sounds and vibrations caused by the ABS, brake assist, VSC and
TRAC
●A sound may be heard from the engine compartment when the hybrid
system is started, just after the vehicle begins to move, if the brake pedal
is depressed forcefully or repeatedly, or 1-2 minutes after the hybrid sys-
tem is stopped. This sound does not indicate that a malfunction has
occurred in any of these systems.
●Any of the following conditions may occur when the above systems are
operating. None of these indicates that a malfunction has occurred.
•Vibrations may be felt through the vehicle body and steering.
•A motor sound may be heard after the vehicle comes to a stop.
•The brake pedal may pulsate slightly after the ABS is activated.
•The brake pedal may move down slightly after the ABS is activated.
■EPS operation sound
When the steering wheel is operated, a motor sound (whirring sound) may
be heard. This does not indicate a malfunction.
■Reduced effectiveness of the EPS system
The effectiveness of the EPS system is reduced to prevent the system from
overheating when there is frequent steering input over an extended period of
time. The steering wheel may feel heavy as a result. Should this occur,
refrain from excessive steering input or stop the vehicle and turn the hybrid
system off. The EPS system should return to normal within 10 minutes.
