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 engine. Turning the engine 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. 693
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. 180)
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.
