increase in the following situations:
• When a vehicle passes by the side of your vehicle
• When the distance between your vehicle and metal objects, such as a guardrail,
wall, sign, or parked vehicle, which may reflect electrical waves toward the rear of
the vehicle, is short• When backing out of a shallow angle park-
ing spot
• When the sensors cannot detect a vehicle

Normal mode
Provides an optimal balance of fuel economy, quietness, and dynamic perfor-
mance. Suitable for city driving. Press the switch to change the driving mode to normal mode when Eco drive mode or
sport mode is selected.
Eco drive mode
Helps the driver accelerate in an eco- friendly manner and improve fuel econ-
omy through moderate throttle characteristics and by controlling the opera-
tion of the air conditioning system (heating/cooling). When not in Eco drive mode, if the driving mode select switch is tu rned to the left, the
Eco drive mode indicator will come on.
Sport mode
Controls the transmission and engine to provide quick, powerful acceleration.

RX350_U_OM48E90U ◆ Dynamic Torque Control AWD system (AWD models)
Automatically switches from front-wheel drive to all-wheel drive (AWD)
according to the driving conditions, he lping to ensure reliable handling and
stability. Examples of conditions wher e the system will switch to AWD are
when cornering, going uph ill, starting off or accele rating, and when the road
surface is slippery due to snow, rain, etc.
◆ Adaptive Variable Suspension System (if equipped)
Controls the damping force of the shock absorber of each wheel according to
the road and driving conditions, helping achieve a comfortable ride, excellent
driveability and a high level of stability.
If SPORT S+ mode is selected using the driving mode select switch, the
damping force will become more su itable for sporty driving. (  P. 3 7 0 )
◆ VDIM (Vehicle Dynamics Integrated Management) (if equipped)
Provides integrated control of the ABS, brake assist, TRAC, VSC, hill-start
assist control, and EPS systems
Helps to maintain vehicle stability when swerving on slippery road surfaces by
controlling the brakes and engine output
◆ Trailer Sway Control
Helps the driver to control trailer sway by selectively applying brake pressure
for individual wheels and reducing dr iving torque when trailer sway is
detected.
