Driving vehicle speed and that helps reduce
the possibility of further damage due to
a secondary collision. ■
TRAC (Traction Control)
Helps to maintain drive power and pre-
vent the drive wheels from spinning
when starting the vehicle or accelerat-
ing on slippery roads ■
Hill-start assist control
Helps to reduce the backward move-
ment of the vehicle when starting on an
uphill ■
VGRS (Variable Gear Ratio Steer-
ing) (if equipped)
Adjusts the front wheel turning angle in
accordance with the vehicle speed and
steering wheel movement ■
DRS (Dynamic Rear Steering) (if
equipped)
Contributes to the turning characteris-
tics and responsiveness of the vehicle
by adjusting the rear wheel angle of the
vehicle in accordance with steering
wheel movement. ■
EPS (Electric Power Steering)
Employs an electric motor to reduce
the amount of effort needed to turn the
steering wheel. ■
Adaptive Variable Suspension Sys-
tem
By independently controlling the
damping force of the shock absorbers
for each of the 4 wheels according to
the road and driving conditions, this
system helps riding comfort with supe-
rior vehicle stabilit y, and helps good vehicle posture.
Also, the damping force changes
depending on the selected driving
mode. ( → P.298) ■
LDH (Lexus Dynamic Handling
system) (if equipped)
Provides integrated control of the
VGRS, DRS and EPS. Contributes to
turning characteristics at low speeds,
responsiveness at medium speeds and
safety at high speeds by controlling the
steering angle of the front and rear
wheels in accordance with the steering
wheel operation and vehicle speed. ■
VDIM (Vehicle Dynamics Inte-
grated Management)
Provides integrated control of the
ABS, brake assist, TRAC, VSC,
hill-start assist control, EPS, VGRS (if
equipped), DRS (if equipped) and
Adaptive Variable Suspension System

When the following four conditions are met,
the hill-start assist control will operate:●
The shift position is in a position other
than P or N (when stating off for-
ward/backward on an upward incline) ●
The vehicle is stopped ●
The accelerator pedal is not depressed ●
The parking brake is not engaged ■
Automatic system cancelation of
hill-start assist control
The hill-start assist control will turn off in any
of the following situations: ●

The accelerator pedal is depressed ●
The parking brake is engaged ●
2 seconds at maximum elapsed after the
brake pedal is released ■
VGRS is disabled when
VGRS may stop operat ing in the following
situations.
In this event, the steering wheel may move
from its straight forward position, but it will
return when the system restarts. ●
When the steering wheel is operated for
an extended period of time while the
vehicle is stopped or is moving very
slowly (on vehicles with LDH, DRS is dis-
abled together with VGRS) ●
When the steering wheel has been held
fully to the left or right
The center position of the steering wheel
may change when VGRS is disabled. How-
ever, the position will return to normal after
VGRS is reactivated.
■
When the 12-volt battery is discon-
nected (vehicles with VGRS)
The steering wheel may move from its
straight forward position, but this will be
corrected automatically when driving.

Sounds and vibrations caused by the
ABS, brake assist, VS C, TRAC, hill-start
assist control and VGRS systems●
A sound may be heard from the engine
compartment when the brake pedal is
depressed repeatedly, when the hybrid
system is started or just after the vehicle
begins to move. This sound does not indi-
cate that a malfunction has occurred in
any of these systems.●
Any of the following conditions may
occur when the above systems are oper-
ating. None of these indicates that a mal-
function has occurred.
• Vibrations may be felt through the vehicle
body and steering.
• A motor sound may be heard also after
the vehicle comes to a stop.■
ECB operating sound
ECB operating sound may be heard in the
following cases, but it does not indicate that
a malfunction has occurred. ●
Operating sound heard from the engine
compartment when the brake pedal is
operated.●
Motor sound of the brake system heard
from the front part of the vehicle when
the driver’s door is opened.●
Operating sound heard from the engine
compartment when one or two minutes
passed after the stop of the hybrid sys-
tem.■
EPS, VGRS and DRS operation sound
When the steering wheel is operated, a
motor sound (whirring sound) may be
heard. This does not indicate a malfunction.
■
Automatic reactivation of TRAC and
VSC systems
After turning the TRAC and VSC systems
off, the systems will be automatically
re-enabled in the following situations:
●
When the power switch is turned off
●
If only the TRAC system is turned off, the
TRAC will turn on when vehicle speed
increases
If both the TRAC and VSC systems are
turned off, automatic re-enabling will not
occur when vehicle speed increases. ■
Reduced effectiveness of the EPS sys-
tem
The effectiveness of the EPS system is
reduced to prevent the system from over-
heating when there is frequent steering
input over an extended period of time. The
steering wheel may feel heavy as a result.
Should this occur, re frain from excessive
steering input or stop the vehicle and turn
the hybrid system off. The EPS system
should return to normal within 10 minutes. ■
Secondary Collision Brake operating
conditions
The vehicle speed is approximately 6 mph
(10 km/h) or more and the airbag sensor
detects a collision. (The Secondary Colli-
sion Brake will not operate when the vehicle
speed is below approximately 6 mph [10
km/h].) ■
Secondary Collision Brake automatic
cancellation
The Secondary Collision Brake is automati-
cally canceled in the following situations: ●
The vehicle speed drops below approxi-
mately 6 mph (10 km/h) ●
A certain amount of time elapses during
operation ●
The accelerator pedal is depressed a
large amount ■
When “Check VGRS System” or
“CHECK DRS” is displayed on the
multi-information display
The VGRS or DRS may not operate prop-
erly. Have the vehicle inspected by your
Lexus dealer.
