Using Eco drive mode
When using Eco drive mode, the torque corresponding to the accelera-
tor pedal depression amount can be generated more smoothly than it is
in normal conditions. In addition, the operation of the air conditioning
system (heating/cooling) will be minimized, improving the fuel econ-
omy. (P. 290)
Use of Hybrid System Indicator
Eco-friendly driving is possible by keeping the indicator needle
(except F SPORT models) or bar display (F SPORT models) of Hybrid
System Indicator within the Eco area. (P. 1 1 4 )
When braking
Make sure to operate the brakes gently and in good time. A greater
amount of electrical energy can be regenerated when slowing down.
Delays
Repeated acceleration and deceleration, as well as long waits at traffic
lights, will lead to bad fuel economy. Check traffic reports before leav-
ing and avoid delays as much as possible. When driving in a traffic
jam, gently release the brake pedal to allow the vehicle to move for-
ward slightly while avoiding overuse of the accelerator pedal. Doing so
can help control excessive gasoline consumption.
Highway driving
Control your speed and keep at a constant speed. 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
regenerated when slowing down.
Hybrid vehicle driving tips
For economical and ecological driving, pay attention to the following
points:

3104-6. Driving tips
IS300h_EE(OM53B95E)
Air conditioning
Use the air conditioning only when necessary. Doing so can help
reduce excessive gasoline consumption.
In summer: When the ambient temperature is high, use the recirculated
air mode. Doing so will help to reduce the burden on the air condition-
ing system and reduce fuel consumption as well.
In winter: Because the gasoline engine will not automatically cut out
until it and the interior of the vehicle are warm, it will consume fuel.
Fuel consumption can be improved by avoiding overuse of the heater.
Checking tire inflation pressure
Make sure to check the tire inflation pressure frequently. Improper tire
inflation pressure can cause poor fuel economy.
Also, as snow tires can cause large amounts of friction, their use on dry
roads can lead to poor fuel economy. Use tires that are appropriate for
the season.
Luggage
Carrying heavy luggage can lead to poor fuel economy. Avoid carrying
unnecessary luggage. Installing a large roof rack can also cause poor
fuel economy.
Warming up before driving
Since the gasoline engine starts up and cuts out automatically when
cold, warming up the engine is unnecessary. Moreover, frequently
driving short distances will cause the engine to repeatedly warm up,
which can lead to excess fuel consumption.
