CAUTION
Observe the following precautions.
Failure to do so may result in death or serious injury.

When taking a nap in the vehicle
Always turn the engine off. Otherwise, if you accidentally move the shift lever
or depress the accelerator pedal, this 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 seri-
ous health hazard.

When braking

When the brakes are wet, drive more cautiously.
Braking distance increases when the brakes are wet, and this 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 vehi-
cles closely and avoid hills or sharp turns that require braking.
In this case, braking is still possible, but the brake pedal should be depressed
more firmly than usual. Also, the braking distance will increase. Have your
brakes fixed immediately.

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 sys-
tems fails, the other will still operate. In this case, the brake pedal should be
depressed more firmly than usual and the braking distance will increase.
Have your brakes fixed immediately.

If the vehicle becomes stuck
Do not spin the wheels excessively when any of the tires is up in the air, or the
vehicle is stuck in sand, mud, etc. This may damage the driveline components
or propel the vehicle forward or backward, causing an accident.
