1842-1. Driving procedures
■
Situations in which EV driv e mode cannot be turned on
It may not be possible to turn EV drive mode on in the following situations. If it can-
not be turned on, a buzzer will sound and a message will be shown on the multi-
information display. ●
The temperature of the hybrid system is high.
The vehicle has been left in the sun, driv en on a hill, driven at high speeds, etc.●
The temperature of the hybrid system is low.
The vehicle has been left in extremely low temperatures for a long period of
time etc.●
The gasoline engine is warming up.●
The hybrid battery (traction battery) is low.●
Vehicle speed is about 25 mph (40 km/h) or more.●
The accelerator pedal is depressed firmly or the vehicle is on a hill etc.●
The windshield defogger is in use.■
Automatic cancelation of EV drive mode
When driving in EV drive mode, the gasoline engine may automatically restart in
the following situations. When EV drive mo de is canceled, a buzzer will sound and
the EV drive mode indicator will flash and go off. ●
The hybrid battery (traction battery) becomes low.●
Vehicle speed becomes more than about 25 mph (40 km/h).
If engine coolant temperature is low, EV drive mode may be canceled when
vehicle speed is below 25 mph (40 km/h).●
The accelerator pedal is depressed firmly or the vehicle is on a hill etc.
When it is possible to inform the driver of automatic cancelation in advance, a prior
notice screen will appear on the multi-information display.■
Possible driving distance when driving in EV drive mode
In EV drive mode, it is possible to drive up about 1 /2 mile (1 km) if driving at a speed
of about 25 mph (40 km/h) or less.
(The distance that is possible depends on the hybrid battery [traction battery] level
and driving conditions.)
■
Fuel economy
RX450h is designed to achieve the best po ssible fuel economy during normal driv-
ing (using the gasoline engine and electric motor [traction motor]). Driving in EV
drive mode more than necessary may lower fuel economy.

When driving ■ Selecting Eco drive mode
When the vehicle is driven in Eco drive mode, vehicle driving force
and operation of the air condit ioning system (heating/cooling) is
controlled to improve fuel efficiency.
Press the menu switch. The multi-information display
will change modes to electronic
features control mode.
Press the “  ” or “  ” switch
until “ECO MODE” appears.
Press the “ENTER” switch to
change to “ON”.
The “ECO MODE” indicator
will be displayed. Each pressing of the switch
turns Eco drive mode on and off.
Press the menu switch to
change to the normal display.STEP 1

Changing shift ranges in S mode
When the shift lever is in the S position, the shift lever can be operated as
follows:
Upshifting
Downshifting
The initial shift range in S mode is set automatically to “5” or “4” accord-
ing to vehicle speed.
■ Shift ranges and their functions
● You can choose from 6 levels of engine braking force.
● A lower shift range will provide gr eater engine braking force than a
higher shift range, and the engi ne speed will also increase.■
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. 342, 350) To improve air con-
ditioning performance, adjust the fa n speed or turn off Eco drive mode. ■
Automatic return to normal driving mode
If snow mode or sport mode is selected , the driving mode will automatically return
to normal mode when the hybrid system is turned off.
■
S mode
●
When the shift range is “5” or lower, holding the shift lever toward “+” sets the
shift range to “6”.
●
To prevent the engine from over-revving, upshifting may automatically occur.

■ Average vehicle speed
Displays the average vehicle speed since the function was reset The function can be reset by pushing the “ENTER” switch for longer than
one second when the average vehicle speed is displayed.
■ Cruising range
Displays the estimated maximum distan ce that can be driven with the
quantity of fuel remaining • This distance is computed based on your average fuel consumption. As
a result, the actual distance that can be driven may differ from that dis-
played.
• When only a small amount of fuel is added to the tank, the display may
not be updated.
When refueling, turn the “POWER” switch off. If the vehicle is refueled
without turning the “POWER” switch off, the display may not be
updated.
■ Tire inflation pressure
Displays inflation pressure of each tire. There is no correlation between
the order of the displayed values and the tire positions. If the inflation pressure of any tire drops a certain amount below the tire infla-
tion pressure value currently memorized in the system, the displayed values
will be highlighted.
It may take a few minutes to display the tire inflation pressure after the
“POWER” switch is turned to ON mode. It may also take a few minutes to
display the tire inflation pressure after inflation pressure has been adjusted.
If the tire pressure warning light is on or flashing, a message describing the
situation will be displayed.

When driving Turning on the high beam headlights
With the headlights on, push the
lever away from you to turn on
the high beams. Pull the lever toward you to the
center position to turn the high
beams off.
Pull the lever toward you to turn
on the high beams. Release the lever to turn them off.
You can flash the high beams with
the headlights on or off.■
Daytime running light system ●
To make your vehicle more visible to other drivers, the daytime running lights
turn on automatically whenever the hybrid system is started and the parking
brake is released. Daytime running lights are not designed for use at night.
Type A: Daytime running lights can be turned off by operating the switch.●
Compared to turning on th e headlights, the daytime running light system offers
greater durability and consumes less electricity, so it can help improve fuel
economy.■
Headlight control sensor
The sensor may not function properly if an
object is placed on the sensor, or anything
that blocks the sensor is affixed to the wind-
shield.
Doing so interferes with the sensor detecting
the level of ambient light and may cause the
automatic headlight system to malfunction.
