the Dynamic Torque Control AWD sys-
tem to normal mode. ( P. 379)
■All-wheel drive lock mode can be operated when
The engine switch is in IGNITION ON mode.
■Automatic release for the 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 25 mph
(40 km/h).
All-wheel drive lock switch (AWD models)
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.

◆ABS (Anti-lock Brake System)
Helps to prevent wheel lock when the br akes are applied suddenly, or if the
brakes are applied while drivin g on a slippery road surface
◆Brake assist
Generates an increased level of br aking force after the brake pedal is
depressed when the system detects a panic stop situation
◆VSC (Vehicle Stability Control)
Helps the driver to contro l skidding when swerving suddenly or turning on
slippery road surfaces.
◆Enhanced VSC (Enhanced Vehicle Stability Control)
Provides cooperative control of the ABS, TRAC, VSC and EPS.
Helps to maintain directional stability when swerving on slippery road sur-
faces by controlling steering performance.
◆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.
◆TRAC (Traction Control)
Helps to maintain drive power and pr event the drive wheels from spinning
when starting the vehicle or accelerating on slippery roads
◆Hill-start assist control
Helps to reduce the backward movement of the vehicle when starting on an
uphill
◆EPS (Electric Power Steering)
Employs an electric motor to reduce the amount of effort needed to turn the
steering wheel
Driving assist systems
To keep driving safety and performance, the following systems operate auto-
matically in response to various drivin g situations. Be aware, however, that
these systems are supplementary and shou ld not be relied upon too heavily
when operating the vehicle.

◆Dynamic Torque Control AWD system (AWD models)
Automatically switches from front-wheel drive to all-wheel drive (AWD)
according to the driving conditions, help ing to ensure reliable handling and
stability. Examples of conditions wher e 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, rain, etc.
◆Adaptive Variable Suspen sion System (if equipped)
Controls the damping force of the shock absorber of each wheel according to
the road and driving conditions, helpin g 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. 374)
◆VDIM (Vehicle Dynamics Integr ated 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

WARNING
■When holding a tire with Selectable Color Trim (if equipped)
■Replacing a flat tire
●Do not touch the disc wheels or the area around the brakes immediately after the
vehicle has been driven.
After the vehicle has been driven the disc wheels and the area around the brakes will
be extremely hot. Touching these areas with hands, feet or other body parts while
changing a tire, etc. may result in burns.
●Failure to follow these precautions could cau se the wheel nuts to loosen and the tire
to fall off, resulting in death or serious injury.
• Never use oil or grease on the wheel bolts or wheel nuts. Oil and grease may cause the wheel nuts to be excessively tightened, leading to
bolt or disc wheel damage. In addition, the oil or grease can cause the wheel nuts
to loosen and the wheel may fall off, causing a serious accident.
Remove any oil or grease from the wheel bolts or wheel nuts.
• Have the wheel nuts tightened with a torque wrench to 76 ft•lbf (103 N•m,
10.5 kgf•m) as soon as possible after changing wheels.
• When installing a tire, only use wheel nuts that have been specifically designed for
that wheel.
• If there are any cracks or deformations in the bolt screws, nut threads or bolt holes
of the wheel, have the vehicle inspected by your Lexus dealer.
●Observe the following precautions. (RX350L)
Failure to do so may result in serious injury:
• Do not try to remove the wheel ornament by hand. Take due care in handling the ornament to avoid unexpected personal injury.
• Lower the spare tire completely to the ground before removing it from under the vehicle.
■Replacing a flat tire for vehicles with power back door
In cases such as when replacing tires, make sure to turn off the power back door main
switch ( P. 101). Failure to do so may cause the back door to operate unintentionally if
the power back door switch is accidentally touched, re sulting in hands and fingers
being caught and injured.
Do not hold the tire by the Selectable Color
Trim. Otherwise, the Selectable Color Trim
may be damaged or may fall off causing the tire
to drop, possibly causing injury.
