GS450h_300h_OM_OM30F92E_(EE)
Hybrid system precautions
The illustration is an exam ple for explanation and may differ from the actual item.
Take care when handling the hybrid system, as it is a high voltage system 
(about 650 V at maximum) as well as  contains parts that become extremely 
hot when the hybrid system is operatin g. Obey the warning labels attached to 
the vehicle.

Vehicles with Adaptive Variable Suspension system 
Normal mode/Customized mode 
Normal mode and customized mode are selected by pressing the driving 
mode select switch. Each time the switch is pressed, the driving mode 
changes between normal mode and customized mode. When customized 
mode is selected, the “Customize” or “CUSTOMIZE” indicator will be illumi- 
nated.
Press the switch to change the driving mode to normal mode when Eco drive mode or sport mode is selected.•Normal mode 
For normal driving. • Customized modeAllows you to drive with the power train, chassis and air conditioning system func- 
tions set to your preferred settings. Customized mode settings  can only be changed on the drive mode customization display of the Remote Touch screen. ( P. 570)
Eco drive mode 
Use Eco drive mode to help achieve low fuel consumption during trips that 
involve frequent accelerating.
When not in Eco drive mode and the driving mode select switch is turned to the left, 
the “ECO” or “ECO MODE” indicator come s on in the multi-information display.

Sport mode 
•SPORT S mode 
Assists acceleration response by controlling the transmission and engine.
When not in SPORT S mode and the driving  mode select switch is turned to the 
right, the “SPORT S” indicator comes on  in the multi-information display, and the Hybrid System Indicator changes to the tachometer. ( P. 109)
•SPORT S+ mode 
Helps to ensure steering performance and driving stability by simultane- 
ously controlling the steering and suspen sion in addition to the hybrid sys- 
tem. Suitable for sporty driving.
When in SPORT S mode and the driving mode  select switch is turned to the right, the “SPORT S+” indicator comes on  in the multi-information display.
■Operation of the air conditioning system in Eco drive mode 
Eco drive mode controls the heating/cooling  operations and fan speed of the air condi- tioning system to enhance fuel efficiency ( P. 346). To improve air conditioning perfor- 
mance, adjust the fan speed or turn off Eco drive mode.
■Automatic operation of the seat heater during Eco drive mode 
Eco drive mode controls the he ating operation and fan speed of the air conditioning sys- 
tem to enhance fuel efficiency. If the driving  mode select switch is switched to Eco drive mode in cold temperatures, the seat heater w ill be automatically operated to assist heat- ing performance.
■Automatic deactivation of sport mode and customized mode 
If the power switch is turned off after driv ing in sport mode or customized mode, the drive mode will be changed to normal mode.

Hybrid vehicle driving tips
◆Using Eco drive mode 
When using Eco drive mode, the torque corresponding to the accelerator 
pedal depression amount can be generate d 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 economy. ( P. 311)
◆Use of Hybrid System Indicator 
The Eco-friendly driving is possible by  keeping the indicate of Hybrid System 
Indicator within Eco area. ( P. 108, 123)
◆Shift lever operation 
Shift the shift lever to D when stopped at a traffic light, or driving in heavy traf- 
fic etc. Shift the shift lever to P when parking. When using the N, there is no 
positive effect on fuel consumption. In the N, the gasoline engine operates but 
electricity cannot be generated. Also, when using the air conditioning system, 
etc., the hybrid battery (traction battery) power is consumed.
◆Accelerator pedal/brake pedal operation
●Drive your vehicle smoothly. Avoid abrupt acceleration and deceleration. 
Gradual acceleration and deceleration will make more effective use of the 
electric motor (traction motor) without having to use gasoline engine 
power.
●Avoid repeated acceleration. Repeated acceleration consumes hybrid bat- 
tery (traction battery) power, resulting in poor fuel consumption. Battery 
power can be restored by driving with the accelerator pedal slightly 
released.
◆When braking 
Make sure to operate the brakes gently and in a timely manner. A greater 
amount of electrical energy can be regenerated when slowing down.
For economical and ecological driving,  pay attention to the following points:
