Driving assist systems
To help enhance driving safety and performance, the following systems
operate automatically in response to various driving situations. Be aware,
however, that these systems are supplementary and should not be relied
upon too heavily when operating the vehicle.
■ABS (Anti-lock Brake System)
Helps to prevent wheel lock when the brakes are applied suddenly, or if
the brakes are applied while driving on a slippery road surface
■Brake assist
Generates an increased level of braking force after the brake pedal is
depressed, when the system detects a panic stop situation
■VSC (Vehicle Stability Control)
Helps the driver to control skidding when swerving suddenly or turning on
slippery road surfaces
■TRC (Traction Control)
Helps to maintain drive power and prevent any of the drive wheels from
spinning when starting the vehicle or accelerating on slippery roads
■Hill-start assist control
→P. 2 7 8
■EPS (Electric Power Steering)
Employs an electric motor to reduce the amount of effort needed to turn
the steering wheel
■Active Torque Control 4WD system (AWD models)
Automatically switches from front-wheel drive to AWD (All-Wheel Drive)
according to driving conditions, helping to ensure reliable handling and
stability. Examples of conditions where the system will switch to AWD are
when cornering, going uphill, starting off or accelerating, and when the
road surface is slippery due to snow or rain etc.
■VSC+ (Vehicle Stability Control +) (if equipped)
Provides cooperative control of the ABS, TRC, VSC and EPS.
Helps to maintain directional stability when swerving on slippery road sur-
faces by controlling steering performance

RX350/270_EE
All-wheel drive lock switch (AWD models)
■All-wheel drive lock mode
●All-wheel drive lock mode is canceled when the brakes are applied to ensure
the ABS and VSC systems operate effectively.
●All-wheel drive lock mode is canceled when the vehicle speed exceeds 40
km/h (25 mph).
All-wheel drive lock mode can be used when a large amount of drive power
needs to be applied to all the wheels, such as when the vehicle gets stuck in
mud and you need to free it.
Press the switch.
The torque of the engine is dis-
tributed to the rear wheels to
the maximum extent possible in
accordance with driving condi-
tions.
Pressing the switch again can-
cels all-wheel drive lock mode
and returns the active torque
control 4WD system to normal
mode. (→P. 2 7 1 )
