4-1. Before driving
WARNING
●The driver should pay extra atten- tion 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 move- ment.
●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 brak-
ing 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. 3 6 6
●Use engine braking (shift position
B) 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.181)
●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, heads or other parts of their
body are not outside the vehicle.
■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, engine brak-ing due to shifting, or changes in
engine speed could cause the vehi- cle to skid.
●After driving through a puddle, lightly depress the brake pedal to make sure that the brakes are func-
tioning properly. Wet brake pads may prevent the brakes from func-tioning properly. If the brakes on
only one side are wet and not func- tioning properly, steering control may be affected.
■When shifting the shift lever
●Do not let the vehicle roll backward
while a forward driving position is selected, or roll forward while the shift lever is in R.
Doing so may result in an accident or damage to the vehicle.
●Do not shift the shift lever to P while the vehicle is moving.Doing so can damage the transmis-
sion and may result in a loss of vehicle control.
●Do not shift the shift lever to R while the vehicle is moving forward.Doing so can damage the transmis-
sion and may result in a loss of vehicle control.
●Do not shift the shift lever to a driv-ing position while the vehicle is moving backward.
Doing so can damage the transmis- sion and may result in a loss of vehicle control.

4-1. Before driving
Driving
Avoid sudden braking that may
cause skidding. Otherwise, the
vehicle may spin out of control. This
is especially true when driving on
wet or slippery road surfaces.
■Sudden acceleration/steering
input/cornering
Executing sharp turns when towing
may result in the trailer colliding
with your vehicle. Decelerate well in
advance when approaching turns
and take them slowly and carefully
to avoid sudden braking.
■Important points regarding
turning
The wheels of the trailer will travel
closer to the inside of the curve
than the wheels of the vehicle. To
make allowance for this, take the
turns wider than you would nor-
mally do.
■Important points regarding
stability
Vehicle movement resulting from
uneven road surfaces and strong
crosswinds will affect handling. The
vehicle may also be rocked by
passing buses or large trucks. Fre-
quently check behind when moving
alongside such vehicles. As soon
as such vehicle movement occurs,
immediately start to decelerate
smoothly by slowly applying the
brakes. Always steer the vehicle
straight ahead while braking.
■Passing other vehicles
Consider the total combined length
of your vehicle and trailer and
ensure that the vehicle-to-vehicle
distance is sufficient before execut-
ing lane changes.
■Transmission information
To maintain engine braking effi-
ciency and charging system perfor-
mance when using engine braking,
do not use the transmission in D.
( P.181)
■If the engine overheats
Towing a loaded trailer up a long,
steep incline in temperatures
exceeding 30°C (85°F) may result
in the engine overheating. If the
engine coolant temperature gauge
indicates that the engine is over-
heating, turn the air conditioning off
immediately, leave the road and
stop the vehicle in a safe place.
( P.414)
■When parking the vehicle
Always place wheel chocks under
the wheels of both the vehicle and
trailer. Firmly set the parking brake
and shift the shift lever to P.
WARNING
F o l l o w a l l t h e i n s t r u c t i o n s d e s c r i b e d i n
this section. Failure to do so could cause an accident resulting in death or serious injury.
■Trailer towing precautions
When towing, make sure that none of
the weight limits are exceeded. ( P.168)

4-5. Using the driving support systems
Driving
■Automatic system cancelation of
hill-start assist control
The hill-start assist control will turn off in any of the following situations:
●The shift lever is shifted to P or N.
●The accelerator pedal is depressed
●The parking brake is engaged
●2 seconds at maximum elapsed after the brake pedal is released
■Sounds and vibrations caused by
the ABS, brake assist, VSC, TRC and hill-start assist control sys-tems
●A sound may be heard from the engine compartment when the brake
pedal is depressed repeatedly, when the hybrid system is started or just after the vehicle begins to move. This
sound does not indicate that a mal- function 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 also after the vehicle comes to a stop.
■ECB operating sound
ECB operating sound may be heard in the following cases, but it does not indi-cate that a malfunction has occurred.
●Operating sound heard from the engine compartment when the brake
pedal is operated.
●Motor sound of the brake system
heard from the front part of the vehicle when the driver’s door is opened.
●Operating sound heard from the engine compartment when one or two minutes passed after the stop of the
hybrid system.
■Active Cornering Assist operation sounds and vibrations
When the Active Cornering Assist is
operated, operation sounds and vibra-
tions may be generated from the brake
system, but this is not a malfunction.
■EPS operation sound
When the steering wheel is operated, a motor sound (whirring sound) may be
heard. This does not indicate a malfunc- tion.
■Automatic reactivation of TRC and VSC systems
After turning the TRC and VSC systems off, the systems will be automatically re-enabled in the following situations:
●When the power switch is turned off
●If only the TRC system is turned off, the TRC will turn on when vehicle speed increases.
If both the TRC and VSC systems are turned off, automatic re-enabling will not occur when vehicle speed
increases.
■Operating conditions of Active Cor- nering Assist
The system operates when the following
occurs.
●TRC/VSC can operate
●The driver is attempting to accelerate while turning
●The system detects that the vehicle is drifting to the outer side
●The brake pedal is released
■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 sys-tem off. The EPS system should return
to normal within 10 minutes.
■Operating conditions of emergency brake signal
When the following conditions are met,
the emergency brake signal will oper-
