2-1. Driving procedures

CAUTION

■

When taking a nap in the vehicle

Always turn the engine off. Otherwise, you may accidentally move the shift lever or

depress the accelerator pedal, which could cause an accident or fire due to engine

overheating. Additionally, if the vehicle is parked in a poorly ventilated 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 power brake assist function does not operate, do not follow other vehicles

closely and avoid downhills or sharp turns that require braking.

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 brake 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

■

When 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 the accelerator and brake pedals

together to hold the vehicle on a hill.
