Hybrid vehicle driving tips
For economical and ecological driving, pay attention to the following
points:
■Using Eco drive mode
When using Eco drive mode, the torq ue corresponding to the accelerator
pedal depression amount can be generated more smoothly than it is in
normal conditions. In addition, the op eration of the air conditioning system
(heating/cooling) will be minimized, improving the fuel economy.
( P. 1 5 7 )
■Use of Hybrid System Indicator
The environmentally-friendly driving is possible by keeping the indicate of
Hybrid System Indicator within Eco area. ( P. 1 6 6 )
■When braking the vehicle
Make sure to operate the brakes ge ntly and in good time. A greater
amount of electrical energy can be retained when slowing down.
■ Delays
Repeated acceleration and deceleration, as well as long waits at traffic
lights, will lead to bad fu el consumption. 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 avoiding overuse of the accelerato r pedal. Doing so can help control
excessive gasoline consumption.
■ Highway driving
Control your speed and keep at a constant speed. Also, before stopping at
a toll booth or similar, allow plenty of time to release the accelerator and
gently apply the brakes. A greater amount of electrical energy can be
retained when slowing down.
