Driving
WARNING
●During normal driving, do not
turn off the EV system. Turning
the EV 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. 5 0 5
●Use regenerative braking to
maintain a safe speed when
driving down a steep hill.
Using the brakes continuously
may cause the brakes to over-
heat and lose effectiveness.
( P.240)
●If “Regenerative braking lim-
ited. Press brake to decelerate.”
appears on the multi-informa-
tion display, firmly depress the
brake pedal to decelerate the
vehicle. ( P.522)
●Do not adjust the position of the
steering wheel, the seat, or the
inside or outside rear view mir-
rors while driving.
Doing so may result in a loss of
vehicle control.
●Always check that all passen-
gers’ arms, heads or other parts
of their body are not outside the
vehicle.
●AWD models: Do not drive the
vehicle off-road.
This is not a AWD vehicle
designed for off-road driving.
Proceed with all due caution if it
becomes unavoidable to drive
off-road.
●Do not drive across a river or
through other bodies of water.
This may cause electric/elec-
tronic components to short cir-
cuit, damage the EV system or
cause other serious damage to
the vehicle.
●Do not drive in excess of the
speed limit. Even if the legal
speed limit permits it, do not
drive over 85 mph (140 km/h)
unless your vehicle has high-
speed capability tires. Driving
over 85 mph (140 km/h) may
result in tire fa ilure, loss of con-
trol and possible injury. Be sure
to consult a tire dealer to deter-
mine whether the tires on your
vehicle are high-speed capabil-
ity tires or not before driving at
such speeds.
■When driving on slippery
road surfaces
●Sudden braking, acceleration
and steering may cause tire
slippage and reduce your ability
to control the vehicle.
●Sudden acceleration or regen-
erative braking due to shift
changing could cause the vehi-
cle to skid, resulting in an acci-
dent.
●After driving through a puddle,
lightly depress the brake pedal
to make sure that the brakes
are functioning properly. Wet
brake pads may prevent the
brakes from functioning prop-
erly. If the brakes on only one
side are wet and not functioning
properly, steering control may
be affected.

■“X-MODE”
 P. 3 8 2
Acceleration/deceleration con-
trol can be performed only by
operating the accelerator pedal,
and the frequency of switching
to the brake pedal can be
greatly reduced. Since the
deceleration when the accelera-
tor pedal is released is stronger
than that of a conventional vehi-
cle, the vehicle can be deceler-
ated smoothly by slowly
releasing the pedal the acceler-
ator pedal without completely releasing it.
When the Regeneration Boost
switch is pressed, the regenera-
tive braking force, when the
accelerator pedal is released,
becomes stronger than usual.
■When Regeneration Boost can-
not be used In the following
cases, the system does not
operate.
●When “X-MODE” is activated (If
equipped)
●When the brake
system or EV
system is malfunctioning
●When regenerative braking is lim-
ited
Regenerative braking may be
restricted in the fo llowing situations:
• When the amount of charge of the traction battery is high
• When the temperature of the trac-
tion battery is low or extremely
high
• When the temperature of the elec-
tric motor or powe r control unit is
extremely high
• When regenerative braking is con- tinually used for a long time
■Regenerative Braking
