Sway warning
Detects the sway of the vehicle within a lane, which is often associated with a
decrease in the driver’s at tention level, and displays the decrease in attention
using a bar display.
The shorter the bar length, the more the driver may need to rest. This display is a part of the LKA (Lan e-Keeping Assist) system. The display is
enabled when the operating conditions of the vehicle sway warning are met.

AWD Control
Displays the driving force applie d to each wheel using segments.
The greater the number of segments di splayed, the greater the driving force
applied.

RX450h_RX450hL _U_OM48F85UContact your Lexus dealer for further in formation about additional requirements
such as a towing kit, etc.Trailer towing (vehicles with towing package) Your vehicle is designed primarily as a passenger-and-load-carrying vehicle.
Towing a trailer can have an adverse im pact on handling, performance, brak-
ing, durability, and fuel consumption. Fo r your safety and the safety of others,
you must not overload your vehicle or trailer. You must also ensure that you
are using appropriate towing equipment, that the towing equipment has been
installed correctly and used properly, and that you employ the requisite driv-
ing habits.
Vehicle-trailer stability and braking pe rformance are affected by trailer sta-
bility, brake performance and setting, tr ailer brakes, the hitch and hitch sys-
tems (if equipped).
To tow a trailer safely, use extreme ca re and drive the vehicle in accordance
with your trailer’s characteri stics and operating conditions.
Lexus warranties do not apply to damage or malfunction caused by towing a
trailer for commercial purposes.

◆ 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 (heat-
ing/cooling) will be minimized, improving the fuel economy. ( → P. 379)
◆ Use of Hybrid System Indicator
The Eco-friendly driving is possible by keeping the indicator needle (except F
SPORT models) or bar display (F SPOR T models) of Hybrid System Indicator
within Eco area. ( → P. 99)
◆ 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, wh en using the air conditioning system,
etc., the hybrid battery (tractio n battery) power is consumed.
◆ Accelerator pedal/brake pedal operation ●
Drive your vehicle smoothly. Avoid ab rupt 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.Hybrid vehicle driving tips For economical and ecological driving, pay attention to the following points:

Driving
RX450h_RX450hL _U_OM48F85U◆ Delays
Repeated acceleration and deceleration, as well as long waits at traffic lights,
will lead to bad fuel economy. Check traffic reports before leaving and avoid
delays as much as possible. When drivin g in a traffic jam, 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 and maintain the vehicle at a co nstant speed. Before stopping at a toll
booth or similar, allow plenty of ti me to release the accelerator and gently
apply the brakes. A greater amount of electrical energy can be regenerated
when slowing down.
◆ 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 conditioning 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. Also, fuel con-
sumption can be improved by av oiding overuse of the heater.
◆ Checking tire inflation pressure
Make sure to check the tire inflation pr essure frequently. Improper tire infla-
tion pressure can cause poor fuel economy.
Also, as snow tires can cause large amou nts of friction, their use on dry roads
can lead to poor fuel economy. Use ti res that are appropriate for the season.
◆ Luggage
Carrying heavy luggage will lead to poor fuel economy. Avoid carrying
unnecessary luggage. Installing a large roof rack will also cause poor fuel
economy.
◆ Warming up before driving
Since the gasoline engine starts up an d cuts out automatically when cold,
warming up the engine is unnecessary. Moreover, frequently driving short dis-
tances will cause the engine to repeated ly warm up, which can lead to excess
fuel consumption.
