4-2. Driving procedures
CAUTION
■When starting the hybrid system
Always start the hybrid system while sitting in the driver’s seat. Do not depress the
accelerator pedal while starting the hybrid system under any circumstances.
Doing so may cause an accident resulting in death or serious injury.
■Caution while driving
If hybrid system failure occurs while the vehicle is moving, do not lock or open the
doors until the vehicle reaches a safe and complete stop. Activation of the steering
lock in this circumstance may lead to an accident, resulting in death or serious
injury.
■Stopping the hybrid system in an emergency
If you want to stop the hybrid system in an emergency while driving the vehicle,
press and hold the power switch for more than 2 seconds, or press it briefly 3 times
or more in succession. (→P. 7 2 9 )
However, do not touch the power switch while driving except in an emergency.
Turning the hybrid system off while driving will not cause loss of steering or braking
control, however, power assist to the steering will be lost. This will make it more dif-
ficult to steer smoothly, so you should pull over and stop the vehicle as soon as it is
safe to do so.

4-5. Using the driving support systems
Driving assist systems
◆ABS (Anti-lock Brake System)
Helps to prevent wheel lock when the brakes are applied suddenly, or if
the brakes are applied while driving on a slippery road surface
◆Brake assist
Generates an increased level of braking force after the brake pedal is
depressed when the system detects a panic stop situation
◆VSC (Vehicle Stability Control)
Helps the driver to control skidding when swerving suddenly or turning
on slippery road surfaces
◆TRAC (Traction Control)
Helps to maintain drive power and prevent the drive wheels from spin-
ning when starting the vehicle or accelerating on slippery roads
◆EPS (Electric Power Steering)
Employs an electric motor to reduce the amount of effort needed to
turn the steering wheel
To help enhance driving safety and performance, the following systems
operate automatically in response to various driving situations. Be
aware, however, that these systems are supplementary and should not
be relied upon too heavily when operating the vehicle.
