■Closing the windows
● The driver is responsible for all the power window operations, including the
operation for the passengers. In order to prevent accidental operation,
especially by a child, do not let a child operate the power windows. It is
possible for children and other passengers to have body parts caught in
the power window. Also, when riding with a child, it is recommended to use
the window lock switch. ( →P. 300)
● When using the wireless remote control or mechanical key and operating
the power windows, operate the power window after checking to make
sure that there is no possibility of any passenger having any of their body
parts caught in the side window. Also do not let a child operate side win-
dow by the wireless remote control or mechanical key. It is possible for
children and other passengers to get caught in the power window.
● When exiting the vehicle, turn the power switch off, carry the key and exit
the vehicle along with the child. There may be accidental operation, due to
mischief, etc., that may possibly lead to an accident.

5-1. Before driving
■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.

5-1. Before driving
WARNING
Observe the following precautions.
Failure to do so may result in death or serious injury.
■When starting the vehicle
Always keep your foot on the brake pedal while stopped with the “READY”
indicator is illuminated. This prevents the vehicle from creeping.
■ When driving the vehicle
● Do not drive if you are unfamiliar with the location of the brake and ac\
cel-
erator pedals to avoid depressing the wrong pedal.
• Accidentally depressing the accelerator pedal instead of the brake
pedal will result in sudden acceleration that may lead to an accident.
• When backing up, you may twist your body around, leading to a diffi- culty in operating the pedals. Make sure to operate the pedals properly.
• Make sure to keep a correct driving posture even when moving the vehicle only slightly. This allows you to depress the brake and accelera-
tor pedals properly.
• Depress the brake pedal using your right foot. Depressing the brake pedal using your left foot may delay response in an emergency, result-
ing in an accident.
● The driver should pay extra attention to pedestrians when the vehicle is
powered only by the electric motor (traction motor). As there is no engine
noise, the pedestrians may misjudge the vehicle’s movement. Even
though the vehicle is equipped with the vehicle proximity notification sys-
tem, drive with care as pedestrians in the vicinity may still not notice the
vehicle if the surrounding area is noisy.
● Do not drive the vehicle over or stop the vehicle near flammable materials.
The exhaust system and exhaust gases can be extremely hot. These hot
parts may cause a fire if there is any flammable material nearby.
● During normal driving, do not turn off the hybrid system. Turning the hybrid
system off while driving will not cause loss of steering or braking control,
however, power assist to the steering will be lost. This will make it more
difficult to steer smoothly, so you should pull over and stop the vehicle as
soon as it is safe to do so.
In the event of an emergency, such as if it becomes impossible to stop the
vehicle in the normal way: →P. 645
