When driving
CT200h_OM_OM76067E_(EE)
Operation of the air conditioning system in Eco drive mode (without navi-
gation system)
Eco drive mode controls the heating/ cooling operations and fan speed of
the air conditioning system to enhance fuel efficiency. (P. 326) To
improve air conditioning performance, adjust the fan speed or turn off Eco
drive mode.
Operation of the air conditioning system in Eco drive mode (with navigation
system)
Eco drive mode controls the heating/cooling operations and fan speed of the
air conditioning system to enhance fuel efficiency. To improve air condi-
tioning performance, adjust the fan speed or turn off Eco drive mode. (Refer
to the “Navigation System Owner’s Manual”.)
For the shift positions
When the “POWER” switch is off, the shift position cannot be changed.
When the “POWER” switch is in ON mode (the hybrid system is not
operating), the shift position can only be changed to N. The shift position
will be changed to N even if the shift lever is shifted to D or R and held
in that position.
When the “READY” indicator is on, the shift position can be changed
from P to D, N or R.
When the “READY” indicator is flashing, the shift position cannot be
changed from P to another position even if the shift lever is operated.
Wait until the “READY” indicator changes from a flashing to a solid
light, and then operate the shift lever again.
The shift position can only be changed to B directly from D.

Hill-start assist control
Hill-start assist control operating conditions
The system operates in the following situations:
• The shift position is in a position other than P.
• The parking brake is not applied.
• The accelerator pedal is not depressed.
Hill-start assist control cannot be operated while the slip indicator light
is illuminated.
Hill-start assist control helps to prevent the vehicle from rolling back-
wards when starting on an incline or slippery slope.
To engage hill-start assist
control, further depress the
brake pedal when the vehicle
is stopped completely.
A buzzer will sound once to
indicate the system is acti-
vated. The slip indicator will
also start flashing.
