Hybrid system precautions
Take care when handling the hybrid system, as it contains a high
voltage system (about 650 V at maximum) as well as parts that
become extremely hot when the hybrid system is operating. Obey
the caution labels attached to the vehicle.

If the engine overheats
Towing a loaded trailer up a long, steep incline in temperatures
exceeding 30C (85F) may result in the engine overheating. If
the engine coolant temperature gauge indicates that the engine is
overheating, turn the air conditioning off immediately, leave the
road and stop the vehicle in a safe place. (P. 915)
When parking the vehicle
Always place wheel chocks under the wheels of both the vehicle
and trailer. Firmly set the parking brake and shift the shift lever
to P.
CAUTION
To avoid accident or injury
Do not tow a trailer when the compact spare tire is installed on your vehi-
cle.
Do not tow a trailer when the tire installed is repaired with the emergency
tire puncture repair kit.
Do not use cruise control (if equipped) or dynamic radar cruise control (if
equipped) when trailer towing.
Vehicle speed in towing
Observe the legal maximum speeds for trailer towing.
Before descending hills or long declines
Reduce speed and downshift. However, never downshift suddenly while
descending steep or long downhill grades.
Operation of the brake pedal
Do not hold the brake pedal depressed often or for long periods of time.
Doing so may result in the brake overheating or reduce braking effects.

The shape of the obstacle may prevent the sensor from detecting it. Pay par-
ticular attention to the following obstacles:
• Wires, fences, ropes, etc.
• Cotton, snow and other materials that absorb sound waves
• Sharply-angled objects
•Low obstacles
• Tall obstacles with upper sections projecting outwards in the direction of
your vehicle
The following situations may occur during use.
• Depending on the shape of the obstacle and other factors, the detection
distance may shorten, or detection may be impossible.
• Obstacles may not be detected if they are too close to the sensor.
• There will be a short delay between obstacle detection and display. Even
at slow speeds, there is a possibility that the obstacle will come within
the sensor’s detection areas before the display is shown and the warning
beep sounds.
• Thin posts or objects lower than the sensor may not be detected for colli-
sion when approached, even if they have been detected once.
• It might be difficult to hear beeps due to the volume of audio system or
air flow noise of air conditioning system.

GS450h_300h_OM_OM30D53E_(EE)
Operation of the air conditioning system in Eco drive mode
Eco drive mode controls the heating/cooling operations and fan speed of the
air conditioning system to enhance fuel efficiency (P. 478). To improve air
conditioning performance, 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 heating operation and fan speed of the air condi-
tioning system to enhance fuel efficiency. If the driving mode select switch is
switched to Eco drive mode in cold temperatures, the seat heater will be auto-
matically operated to assist heating performance.
Sport mode automatic deactivation
Sport mode is automatically deactivated if the power switch is turned off
after driving in sport mode.
Operation of the Eco drive mode (on some models)
The driving mode will set to Eco drive mode each time the power switch is
turned to ON 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 generated more
smoothly than it is in normal conditions. In addition, the opera-
tion of the air conditioning system (heating/cooling) will be min-
imized, improving the fuel economy. (P. 392)
Use of Hybrid System Indicator
The Eco-friendly driving is possible by keeping the indicate of
Hybrid System Indicator within Eco area. (P. 126)
When braking the vehicle
Make sure to operate the brakes gently 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 fuel consumption. Check traffic
reports before leaving 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 over-
use of the accelerator 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
For economical and ecological driving, pay attention to the follow-
ing points:

the accelerator and gently apply the brakes. A greater amount of
electrical energy can be retained when slowing down.
Air conditioning
Use the air conditioning only when necessary. Doing so can help
control excessive gasoline consumption.
In summer: In high temperatures, use the recirculated air mode.
Doing so will help to reduce the burden on the air conditioner
and reduce fuel consumption as well.
In winter: Because the gasoline engine will not automatically cut
out until the gasoline engine and the interior of the vehicle are
warm, it will consume fuel. Also, 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 consumption.
Also, as snow tires can cause large amounts of friction, their use
on dry roads can lead to poor fuel consumption. Use a tire that is
appropriate for the season.
Luggage
Carrying heavy luggage can lead to poor fuel consumption.
Avoid carrying unnecessary luggage. Installing a large roof rack
can also cause poor fuel consumption.
Warming up before driving
Since the gasoline engine starts up and cuts out automatically
when cold, warming up the engine is unnecessary. Moreover, fre-
quently driving short distances will cause the engine to repeat-
edly warm up, which can lead to poor fuel consumption.
