■When starting off on an uphill
The hill-start assist control will activate. ( →P. 232)
■ For fuel-efficient driving
Keep in mind that fuel cell vehicles are similar to conventional vehicles, and it
is necessary to refrain from activities such as sudden acceleration. ( →P. 94)
■ Driving in the rain
●Drive carefully when it is raining, because visibility will be reduced, the win-
dows may become fogged-up, and the road will be slippery.
● Drive carefully when it starts to rain, because the road surface will be espe-
cially slippery.
● Refrain from high speeds when driving on an expressway in the rain,
because there may be a layer of water between the tires and the road sur-
face, preventing the steering and brakes from operating properly.
■ Restraining the fuel cell system output (Brake Override System)
● When the accelerator and brake pedals are depressed at the same time, the
fuel cell system output may be restrained.
● A warning message is displayed on the multi-information display while the
system is operating. If a warning message is shown on the multi-information
display, read the message and follow the instructions.
■ Restraining sudden star t (Drive-Start Control)
● When the following unusual operation is performed, the fuel cell system out-
put may be restrained.
• When the shift lever is shifted from R to D, D to R, N to R, P to D, or P to
R with the accelerator pedal depressed, a warning message appears on
the multi-information display. If a warning message is shown on the multi-
information display, read the message and follow the instructions.
• When the accelerator pedal is depressed too while the vehicle is in
reverse.
● While Drive-Start Control is being activated, your vehicle may have trou-
ble escaping from the mud or fresh snow. In such case, deactivate TRAC
