CAUTION
When taking a nap in the vehicle
■
Always turn the hybrid system off. Otherwise, you may accidentally move the shift
lever or depress the accelerator pedal, which could cause an accident or fire due to
hybrid system overheating. Additionally, if the vehicle is parked in a poorly venti-
lated area, exhaust gases may collect and enter the vehicle, leading to death or a
serious health hazard.
When braking the vehicle
■
When the brakes are wet, drive more cautiously.
●
Braking distance increases when the brakes are wet, and may cause one side of
the vehicle to brake differently than the other side. Also the parking brake may
not securely hold the vehicle.
If the brake actuator does not operate, do not follow other vehicles closely and
●
avoid downhill or sharp turns that require making.
In this case, braking is still possible, but it will require more force on the pedal than
usual. Braking distance may also increase.
Do not pump the brake pedal if turning the hybrid system off.
●
Each push on the brake pedal uses up the reserve for the power-assisted brakes.
The brake system consists of 3 individual hydraulic systems: If one of the systems
●
fails, the other will still operate. In this case, the brake pedal should be depressed
more firmly than usual and braking distance becomes longer.
Do not drive your vehicle with only a single brake system. Have your brakes fixed
immediately.
