2-1. Driving procedures
CAUTION
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 (vehicles with an automatic transmission) or 1
●
(vehicles with a manual transmission) 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 engine
●
from the transmission. Engine braking is not available when N is selected.
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. 557
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. 154)
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 bodies 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 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.
