2-1. Driving procedures
CAUTION
n When driving the vehicle
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.
Use engine braking (downshift) to maintain a safe speed when driving
l
down a steep hill.
Using the brakes continuously may cause the brakes to overheat and lose
effectiveness. (→P. 128,130)
l 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.
l 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 bod-
l
ies are not outside the vehicle, as this may result in death or serious injury.
l Do not drive in excess of the speed limit. Even if the legal speed limit per-
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.
Sudden changes in engine speed, such as engine braking caused by up-
l
shifting or down-shifting, may cause the vehicle to skid, resulting in an
accident.
