pletely.
A buzzer will sound once to indicate
the system is activated. The slip indica-
tor will also start flashing.
■Hill-start assist control operating conditions
●The system operates in the following situations:
• The shift lever is in a position other than P.
• The parking brake is not applied.
• The accelerator peda l is not depressed.
●Hill-start assist control cannot be operated while the slip indicator light is illumi-
nated.
■Hill-start assist control
●While hill-start assist control is operating, the brakes remain automatically applied
after the driver releases the brake pedal. The stop lights and the high mounted
stoplight turn on.
●Hill-start assist control operates for about 2 seconds after the brake pedal is
released.
●If the slip indicator does not flash and the buzzer does not sound when the brake

4-6. Driving tips
Hybrid vehicle driving tips (hybrid vehicles)
When using Eco drive mode, the torque corresponding to the accelerator
pedal depression amount can be generated more smoothly than it is in
normal conditions. In addi tion, the operation of the air conditioning system
(heating/cooling) will be minimized, improving the fuel economy.
( P. 311)
The Eco-friendly driving is possible by keeping the indicate of Hybrid Sys-
tem Indicator within Eco area. ( P. 100)
Make sure to operate the brakes gently and in good time. A greater
amount of electrical energy can be retained when slowing down.
Repeated acceleration and deceleration , as well as long waits at traffic
lights, will lead to bad fuel consumpti on. Check traffic reports before leav-
ing and avoid delays as much as possible. When encountering a delay,
gently release the brake pedal to allow the vehicle to move forward
slightly while avoi ding overuse of the accelerator pedal. Doing so can help
control excessive gasoline consumption.
For economical and ecological drivin g, pay attention to the following
points:
Using Eco drive mode
Use of Hybrid System Indicator
