CAUTION
■
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 power brake assist function 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 the engine stalls.
Each push on the pedal uses up the reserve for the power-assisted
brakes.
● The brake system consists of 2 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.
NOTICE
■While driving the vehicle
●Do not depress the accelerator and brake pedals at the same time during
driving. If the brake pedal is depressed while driving with the accelerator
pedal depressed, driving torque may be restrained.
● Do not use the accelerator pedal or depress accelerator and brake pedals
at the same time to hold the vehicle on a hill.

press and hold the “ENGINE START STOP” switch for more than 3 seconds,
or press it briefly 3 times or more in succession.
