4Maintenance and care5When trouble arises

172 2-1. Driving procedures
CAUTION
■When starting the vehicle
Always keep your foot on the brake pedal while stopped with the hybrid sys-
tem operating. This prevents the vehicle from creeping.
■ 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 brake
pedal will result in sudden acceleration that may lead to an accident
that could result in death or serious injury.
• 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, allowing you to depress the brake and accelerator
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 attention to pedestrians when the vehicle is pow-
ered only by the electric motor (traction motor). Because there is no
engine noise, the pedestrians may misjudge the vehicle’s movement.
● Do not drive the vehicle over or st op the vehicle near flammable materials.
The exhaust system and exhaust gases can be extremely hot. This may
cause a fire if there is any flammable material nearby.
● Do not let the vehicle roll backwards while the shift lever is in a driving
position, or roll forward while the shift lever is in R.
Doing so may cause the hybrid system not to operate or lead to poor
brake and steering performance, resulting in an accident or damage to the
vehicle.
● If the smell of exhaust is noticed inside the vehicle, open the windows and
check that the back door is closed. Large amounts of exhaust in the vehi-
cle can cause driver drowsiness and an accident, resulting in death or a
serious health hazard. Have the vehicle inspected by your Toyota dealer
immediately.

When driving
CAUTION
●
Do not shift the shift lever 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 lever 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 lever to D while the vehicle is moving backward.
Doing so can damage the transmission and may result in a loss of vehicle\
control.
● Moving the shift lever to N while the vehicle is moving will disengage the
hybrid system. Engine braking is not available with the hybrid system dis-
engaged.
● 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,
but the power assist to these systems will be lost. This will make it more
difficult to steer and brake, so you should pull over and stop the vehicle as
soon as it is safe to do so.
However, in the event of an emergency, such as if it becomes impossible
to stop the vehicle in the normal way: P. 567
● Use engine braking 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. 191)
● When stopped on an inclined surface, use the brake pedal and parking
brake to prevent the vehicle from rolling backward or forward and causing
an accident.
● Do not adjust the position 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 that can cause accidents
that may result in death or serious injury.
● Always check that all passengers' arms, heads or other parts of their bod-
ies are not outside the vehicle, as this may result in death or serious injury.

174 2-1. Driving procedures
CAUTION
●Do not drive in excess of the speed limit. Even if the legal speed limit per-
mits 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
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 slippage and
reduce your ability to control the vehicle, resulting in an accident.
● Sudden changes in braking force, such as engine braking and regenera-
tive braking caused by shifting the shift lever to the B position, may cause
the vehicle to skid, resulting in an accident.
● 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 properly. If the brakes on only one side are wet
and not functioning properly, steering control may be affected, resulting in
an accident.
■ When shifting the shift lever
Be careful not to shift the shift lever with the accelerator pedal depressed.
This may lead to unexpected rapid acceleration of the vehicle that may
cause an accident and result in death or serious injury.
■ When the vehicle is stopped
●Do not race the hybrid system.
If the vehicle is in any gear other than P or N, the vehicle may accelerate
suddenly and unexpectedly, and may cause an accident.
● Do not leave the vehicle with the hybrid system on for a long time.
If such a situation cannot be avoided, park the vehicle in an open space
and check that exhaust fumes do not enter the vehicle interior.
● In order to prevent accidents due to the vehicle rolling away, always keep
depressing the brake pedal while the “READY” indicator is on. Apply the
parking brake as necessary.
● If the vehicle is stopped on an incline, in order to prevent accidents caused
by the vehicle rolling forward or backward, always depress the brake pedal
and securely apply the parking brake as needed.

178 2-1. Driving procedures
NOTICE
■Avoiding damage to vehicle parts
●Do not turn the steering wheel fully in either direction and hold it there for a
long time.
Doing so may damage the power steering motor.
● When driving over bumps in the road, drive as slowly as possible to avoid
damaging the wheels, underside of the vehicle, etc.
■ When encountering flooded roads
Do not drive on a road that has flooded after heavy rain etc. Doing so may
cause the following serious damage to the vehicle.
●Engine stalling
● Short in electrical components
● Engine damage caused by water immersion
In the event that you drive on a flooded road and the vehicle is flooded, be
sure to have your Toyota dealer check the following.
● Brake function
● Changes in quantity and quality of oil and fluid used for the engine, hybrid
transaxle, rear motor transaxle, etc.
● Lubricant condition for the bearings and suspension joints (where possi-
ble) and the function of all joints, bearings, etc.

When driving
CAUTION
■
When starting the hybrid system
Always start the hybrid system while sitting in the driver's seat. Do not
depress the accelerator while starting the hybrid system under any circum-
stances.
Doing so may cause an accident resulting in death or serious injury.
■ Caution when driving
Do not turn the engine switch to the “LOCK” position while driving. If, in an
emergency, you must turn the hybrid system off while the vehicle is moving,
turn the key only to the “ACC” position.
NOTICE
■To prevent 12-volt battery discharge
Do not leave the key in the “ACC” or “ON” position for long periods without
the hybrid system on.
■ When starting the hybrid system
●Do not crank for more than 30 seconds at a time. This may overheat the
starter and wiring systems.
● Do not race a cold hybrid system.
● If the hybrid system becomes difficult to start or stalls frequently, have the
hybrid system checked immediately.
