RX450h_U_OM0E013U ◆ When stopped/during start off
The gasoline engine stops* when the vehi cle is stopped. During start off, the
electric motor (traction mo tor) drives the vehicle. At slow speeds or when
traveling down a gentle slope, the engine is stopped* and the electric motor
(traction motor) is used.
When the shift lever is in N, the hybrid battery (traction battery) is not being
charged.
* : When the hybrid battery (traction battery) requires charging or the engine is warm-
ing up, etc., the gasoline engine will not automatically stop. (  P. 7 8 )
◆ During normal driving
The gasoline engine is predominantly used. The electric motor (traction
motor) charges the hybrid battery (traction battery) as necessary.
◆ When accelerating sharply
When the accelerator pedal is depressed heavily, the power of the hybrid bat-
tery (traction battery) is added to that of the gasoline engine via the electric
motor (traction motor).
◆ When braking (regenerative braking)
The wheels operate the electric motor (traction motor) as a power generator,
and the hybrid battery (tr action battery) is charged.
When the gasoline engine is off while driving, a sound is produced to warn
pedestrians, people riding bicycles or ot her people and vehicles in the surround-
ing area that the vehicle is approaching. The pitch of the sound varies according
to the vehicle speed. When the vehicle speed becomes approximately 15 mph
(25 km/h) or more, the notification sound turns off.Vehicle proximity notification system

Road accident cautions
Observe the following precautions to reduce the risk of death or serious injury:●
Pull your vehicle off the road, shift the shift lever to P, apply the parking brake, and
turn the hybrid system off. ●
Do not touch the high voltage parts, cables and connectors. ●
If electric wires are exposed inside or ou tside your vehicle, an electric shock may
occur. Never touch exposed electric wires. ●
If a fluid leak occurs, do not touch the fluid as it may be strong alkaline electrolyte
from the hybrid battery (traction battery). If it comes into contact with your skin or
eyes, wash it off immediately with a large amount of water or, if possible, boric acid
solution. Seek immediate medical attention. ●
If a fire occurs in the hybrid vehicle, leave the vehicle as soon as possible. Never use a
fire extinguisher that is not meant for el ectric fires. Using even a small amount of
water may be dangerous. ●
If your vehicle needs to be towed, do so with front wheels (2WD models) or four
wheels (AWD models) raised. If the wheels connected to the electric motor (traction
motor) are on the ground when towing, the motor may continue to generate electric-
ity. This may cause a fire. (  P. 5 3 0 )●
Carefully inspect the ground under the vehicle. If you find that liquid has leaked onto
the ground, the fuel system may have been damaged. Leave the vehicle as soon as
possible.

using a bar display.
The shorter the bar length, the more the driver may need to rest. This display is a part of the LDA (Lane Departure Alert with steering control)/LKA
(Lane-Keeping Assist) system. The displa y is enabled when the operating condi-
tions of the vehicle sway warning are met. (  P. 292, 302)■
AWD Control (if equipped)
Displays the driving force applie d to each wheel using segments.
The greater the number of segments displayed, the greater the driving force
applied.

When adjusting the seat position ●
Take care when adjusting the seat position to ensure that other passengers are not
injured by the moving seat. ●
Do not put your hands under the seat or near the moving parts to avoid injury.
Fingers or hands may become jammed in the se at mechanism.●
Make sure to leave enough space around the feet so they do not get stuck.■
Seat adjustment
To reduce the risk of sliding under the lap belt during a co llision, do not recline the seat
more than necessary.
If the seat is too rec lined, the lap belt may slide past the hips and apply restraint forces
directly to the abdomen, or your neck may contact the shoulder belt, increasing the risk
of death or serious injury in the event of an accident.
Adjustments should not be ma de while driving as the seat may unexpectedly move and
cause the driver to lose control of the vehicle.
