■Restraining hybrid system outp ut (Brake Override System)
● When the accelerator and brake pedals are depressed at the same time, the
hybrid system output may be restrained.
● A warning message is displayed on the multi-information display while the
system is operating. If a warning message is shown on the multi-information
display, read the message and follow the instructions.
■ “ECO Accelerator Guidance” ( →P. 213)
It is easier to drive in an Eco-friendly manner by driving while referring to the
“ECO Accelerator Guidance” display. Also, by using the “ECO Accelerator
Guidance”, it is easier to increase the Eco score evaluation.
● When starting off:
While staying within the “ECO Accelerator Guidance” range, gradually
depress the accelerator pedal and accelerate to the desired speed. If exces-
sive acceleration is avoided, the “Eco-Start” score will increase.\
● When driving:
After accelerating to the desired speed, release the accelerator pedal and
drive at a stable speed within the “ECO Accelerator Guidance” range. By
keeping the vehicle within the “ECO Accelerator Guidance” range, the “Eco-
Cruise” score will increase.
● When stopping:
When stopping the vehicle, early releasing the accelerator pedal will cause
the “Eco-Stop” score to increase.
■ Restraining sudden star t (Drive-Start Control)
● When the following unusual operation is performed, the hybrid system out-
put may be restrained.
• When the shift position is shifted from R to D, D/B to R, N to R, P to D, P
to R with the accelerator pedal depressed, a warning message appears
on the multi-information display. If a warning message is shown on the
multi-information display, read the message and follow the instructions.
• When the accelerator pedal is depressed too much while the vehicle is in
reverse.
● While Drive-Start Control is being activated, your vehicle may have trou-
ble escaping from the mud or fresh snow. In such case, deactivate TRAC
(→P. 477) to cancel Drive Start Control so that the vehicle may become
able to escape from the mud or fresh snow.

WARNING
Observe the following precautions.
Failure to do so may result in death or serious injury.
■When shifting the shift position
● Do not let the vehicle roll backward while a forward driving position is
selected, or roll forward while the shift position is in R.
Doing so may result in an accident or damage to the vehicle.
● Do not shift the shift position to P while the vehicle is moving.
Doing so can damage the transmission and may result in a loss of vehicle
control.
● Do not shift the shift position to R while the vehicle is moving forward\
.
Doing so can damage the transmission and may result in a loss of vehicle
control.
● Do not shift the shift position to a driving position while the vehicle is mov-
ing backward.
Doing so can damage the transmission and may result in a loss of vehicle
control.
● Moving the shift position to N while the vehicle is moving will disengage
the hybrid system. Engine braking is not available with the hybrid system
disengaged.
● Be careful not to change the shift position with the accelerator pedal
depressed.
Changing the shift position to any position other than P or N may lead to
unexpected rapid acceleration of the vehicle that may cause an accident
and result in death or serious injury.
After changing the shift position, make sure to confirm the current shift
position displayed on the shift position indicator inside the meter.

■ When the ambient temperature is low, such as during winter driving con-
ditions
● When starting the hybrid system, the flashing time of the “READY” indicator
may be long. Leave the vehicle as it is until the “READY” indicator is steady
on, as steady means the vehicle is able to move.

■For the shift positions
●When the power switch is off, the shift position cannot be changed.
● When the power switch is in ON mode (the hybrid system is not operating),
the shift position can only be changed to N. The shift position will be
changed to N even if the shift lever is shifted to D or R and held in that posi-
tion.
● When the “READY” indicator is on, the shift position can be changed from P
to D, N or R.
● When the “READY” indicator is flashing, the shift position cannot be
changed from P to another position even if the shift lever is operated. Wait
until the “READY” indicator changes from a flashing to a solid lig\
ht, and then
operate the shift lever again.
● The shift position can only be changed to B directly from D.
In addition, if an attempt is made to change the shift position by moving the
shift lever or by pressing the P position switch in any of the following situa-
tions, the buzzer will sound and the shifting operation will be disabled or the
shift position will automatically change to N. When this happens, select an
appropriate shift position.
● Situations where the shifting operation will be disabled:
• When an attempt is made to change the shift position from P to another
position by moving the shift lever without depressing the brake pedal.
• When an attempt is made to change the shift position from P or N to B by
moving the shift lever.
• When an attempt is made to change the shift position from P to another position by moving the shift lever while the charging cable is connected to
the vehicle.
● Situations where the shift position will automatically change to N:
• When the P position switch is pressed while the vehicle is running.

• When an attempt is made to select the R position by moving the shift
lever when the vehicle is moving forward.
*2
• When an attempt is made to select the D position by moving the shiftlever when the vehicle is moving in reverse.
*3
• When an attempt is made to change the shift position from R to B bymoving the shift lever.
*1: Shift position may be changed to P when driving at extremely low
speeds.
*2: Shift position may be changed to R when driving at low speeds.
*3: Shift position may be changed to D when driving at low speeds.
● If N is selected while driving at a certain speed, even if the shift lever is not
held in the N position, the shift position changes to N. In this situation, the
buzzer sounds and a confirmation message is displayed on the multi-infor-
mation display to inform the driver that the shift position has changed to N.
