2-1. Driving procedures
CAUTION
n When driving the vehicle
Do not under any circumstances shift the shift lever to P, R or N (automatic
l
transmission) or R (manual transmission) 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.
l
Doing so may cause the engine brake to not operate properly and lead to
an accident.
Do not turn the engine off while driving.
l
The power steering and brake booster systems will not operate properly if
the engine is not running.
l 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
effectiveness. (→P. 112,114)
When stopped on an inclined surface, use the brake pedal and parking
l
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
l
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-
l
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-
l
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.
When driving on slippery road surfaces
n
Sudden braking, acceleration and steering may cause tire slippage and
l
reduce your ability to control the vehicle, resulting in an accident.
