Driving
Stop the vehicle completely.
Set the parking brake. ( P. 3 4 9 )
Shift the shift position to P. ( P. 343)
Check that the shift position indicator shows P.
Press the power switch to stop the hybrid system.
Slowly release th e brake pedal.
Lock the door, making sure that you have the electronic key on your
person.
If parking on a hill, block the wheels as needed.
Firmly set the parking brake with the brake pedal depressed, an d
then shift the shift position to D.
Release the brake pedal and gen tly depress the accelerator pedal.
Release the parking brake.
■ When starting off on an uphill
The hill-start assist control will activate. ( P. 490)
■ For electricity-saving and fuel-efficient driving
Understand the system characteristics of the vehicle to use the functions of
the hybrid system. Also, keep in mind that hybrid vehicles are similar to con-
ventional vehicles, and it is necessary to refrain from activit ies such as sud-
den acceleration. Refer to “Plug-in hybrid vehicle driving tips ” (P. 105).
■ Driving in the rain
●Drive carefully when it is raining, because visibility will be reduced, the win-
dows may become fogged-up, and the road will be slippery.
● Drive carefully when it starts to rain, because the road surface will be espe-
cially slippery.
● Refrain from high speeds when driving on an expressway in the r ain,
because there may be a layer of water between the tires and the road sur-
face, preventing the steering and brakes from operating properl y.

■Restraining the hybrid system o utput (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. ( P. 677)
■ “ECO Accelerator Guidance” (P. 226)
It is easier to drive in an Eco-friendly manner by driving whil e 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 spe ed. If exces-
sive acceleration is avoided, the “Eco-Start” score will increa se.
● When driving:
After accelerating to the desired speed, release the accelerato r 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 peda l will cause
the “Eco-Stop” score to increase.
■ Restraining sudden start (Drive-Start Control)
● When the following unusual operation is performed, the hybrid s ystem out-
put may be restrained.
• When the shift position is shifted from R to D/B, D/B to R, N to R, P to D/
B
*, 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 t he instruc-
tions.
• When the accelerator pedal is depressed too much while the veh icle 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. 490) to cancel Drive Start Control so that the vehicle may b ecome
able to escape from the mud or fresh snow.
*: Depending on the situation, the shift position may not be chan ged.

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 creepi ng.
■ When driving the vehicle
● Do not drive if you are unfamiliar with the location of the brake and accel-
erator pedals to avoid depressing the wrong pedal.
• Accidentally depressing the accelerator pedal instead of the b rake
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 t he
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 v ehicle is
powered only by the electric motor (traction motor). As there i s no engine
noise, the pedestrians may misjudge the vehicle’s movement. Even
though the vehicle is equipped with the vehicle proximity notif ication 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 flammabl e materials
such as leaves, paper or rags.
The exhaust system and exhaust gases can be extremely hot. Thes e 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 m ake it more
difficult to steer smoothly, so you should pull over and stop t he 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. 653

Driving
WARNING
Observe the following precautions.
Failure to do so may result in death or serious injury.
■When driving the vehicle
● Use engine braking (shift position B instead of shift position D) to maintain
a safe speed when driving down a steep hill.
Using the brakes continuously may cause the brakes to overheat and lose
effectiveness. ( P. 343)
● Do not adjust the positions of the steering wheel, the seat, or the inside or
outside rear view mirrors while driving.
Doing so may result in a loss of vehicle control.
● Always check that all passengers’ arms, head or other parts of their body
are not outside the vehicle.
● Do not drive across river crossings or through other bodies of water.
This may cause electric/electronic components to short circuit, damage
the hybrid system or cause other serious damage to the vehicle.
● Do not drive in excess of the speed limit. Even if the legal sp eed limit per-
mits it, do not drive over 85 mph (140 km/h) unless your vehicl e has high-
speed capability tires. Driving over 85 mph (140 km/h) may resu lt in tire
failure, loss of control and possible injury. Be sure to consult a tire dealer
to determine whether the tires on your vehicle are high-speed capability
tires or not before driving at such speeds.
■ When driving on slippery road surfaces
● Sudden braking, acceleration and steering may cause tire slippa ge and
reduce your ability to control the vehicle.
● Sudden acceleration, engine braking due to shifting, or changes in engine
speed could cause the vehicle to skid, resulting in an accident.
● After driving through a puddle, depress the brake pedal to make sure that
the brakes are functioning properly. Wet brake pads may prevent the
brakes from functioning properly. If the brakes on only one sid e are wet
and not functioning properly, steering control may be affected.
