2-1. Driving procedures

When driving
CAUTION
●
If the smell of exhaust is noticed inside the vehicle, open the windows and
check that the trunk is closed. Large amounts of exhaust in the vehicle can
cause driver drowsiness and an accident, resulting in death or a serious
health hazard. Have the vehicle inspected by your Toyota dealer immedi-
ately.
● Do not under any circumstances shift the shift lever to P or R while the
vehicle is moving.
Doing so can cause significant damage to the transmission system and
may result in a loss of vehicle control.
● Do not shift the shift lever to N while the vehicle is moving.
Doing so may cause insufficient engine braking and lead to an accident.
● Do not turn the hybrid system off while driving.
The power steering and brake systems will not operate properly if the
hybrid system is off.
● 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. 140)
● 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.
● 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.

NOTICE
■To prevent damage to the engine and its components
The gasoline engine may be overheating if the engine coolant temperature
gauge is in the red zone (H). In this case, immediately stop the vehic\
le in a
safe place. Check the gasoline engine after it has cooled completely.
(
P. 438)

166 2-4. Using other driving systems
When VSC and TRAC are operatingIf the vehicle is in danger of slip-
ping or the front wheels spin, the
indicator flashes to indicate that
VSC/TRAC have been engaged.
A buzzer (intermittent) sounds to
indicate that VSC is operating.
■Sounds and vibrations caused by ABS, brake assist, VSC and TRAC
●A sound may be heard from the engine compartment when the hybrid
system is started or just after the vehicle begins to move. This sound
does not indicate that a malfunction has occurred in any of these sys-
tems.
● 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 after the vehicle comes to a stop.
■ Reduced effectiveness of EPS
The effectiveness of EPS 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 system off.
The system should return to normal within 10 minutes.
■ If the slip indicator comes on...
It may indicate a malfunction in the VSC and TRAC. Contact your Toyota
dealer.
