GS450h_U (OM30D01U)

4-1. Before driving

CAUTION

Observe the following precautions.

Failure to do so may result in death or serious injury.

■

When driving the vehicle

●

During normal driving, do not turn off the hybrid system. Turning the hybrid sys-

tem 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. 703

●

Use engine braking (downshift) to maintain a safe speed when driving down a

steep hill.

Using the brakes continuously may cause the brakes to overheat and lose effec-

tiveness. (

→

P. 199)

●

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.

●

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 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.
