2-1. Driving procedures
CAUTION
●With automatic transmission vehicles, 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 (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. 5 1 8
●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. 1 4 7 )
●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.

When driving
NOTICE
■When driving the vehicle
●Do not depress the accelerator and brake pedals at the same time during driving.
If the brake pedal is depressed whil e driving with the accelerator pedal
depressed, driving torque may be restrained.
With automatic transmission vehicles
●Do not use the accelerator pedal or depress the accelerator and brake pedals
together to hold the vehicle on a hill.With manual transmission vehicles
●Do not rest your foot on the clutch pedal while driving.
Doing so may cause clutch trouble.
●Do not use any gear other than the first gear when starting off and moving for-
ward.
Doing so may damage the clutch.
●Do not use the clutch to hold the vehicle when stopping on an uphill grade.
Doing so may damage the clutch.
■When parking the vehicle
With automatic transmission vehicles, always put the shift lever in P. Failure to do so
may cause the vehicle to move or the vehicle may accelerate suddenly if the accel-
erator pedal is accidentally depressed.
■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 damag-
ing the wheels, underside of the vehicle, etc.
