■Operating conditions
After stopping the engine, the vehicle will remain lowered for a maximum of 60
seconds.
●Height selector switch (driver's side instrument panel)
• While the engine is running, any vehicle height mode can be selected.
• Luggage mode can only be selected when the shift lever is in P position.
●Height selector switch (luggage compartment)
• When the engine is running and the shift lever is in the P position, any vehicle
height other than “LO” mode can be selected.
• When the “ENGINE START STOP” switch is turned off, the vehicle height
can only be lowered (only the “∨” side of the switch can be operated).
This switch can only be operated when the back door is open.
●Height control off switch
When the vehicle is stopped with the “ENGINE START STOP” switch in IGNI-
TION ON mode, vehicle height control can be disabled/re-enabled.
■When changing vehicle height modes
Before operating the height selector switch to raise/lower the vehicle height,
ensure that there are no objects in the surrounding area that could damage the
vehicle.
■When “N” mode is selected
During high speed driving, the vehicle height will automatically change to that of
“LO” mode.
■When “HI” mode is selected
The vehicle height will change to that of “N” mode when vehicle speed reaches 50
km/h (31 mph) or when vehicle speed has exceeded 30 km/h (19 mph) for approx-
imately 10 seconds. Even if vehicle speed is reduced below 30 km/h (19 mph), the
vehicle height will not automatically return to “HI” mode.
■When “LO” mode is selected
The vehicle height will change to that of “N” mode when the engine is restarted.

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

When the VSC/TRC systems are operating
If the vehicle is in danger of slip-
ping or if any of the drive wheels
spins, the slip indicator flashes to
indicate that the VSC/TRC sys-
tems are operating.
■VDIM (Vehicle Dynamics Integrated Management) (if equipped)
Provides integrated control of the ABS, brake assist, TRC, VSC, hill-start
assist control and EPS systems
Helps to maintain vehicle stability when swerving on slippery road sur-
faces by controlling the brakes and engine output
■PCS (Pre-Crash Safety system) (if equipped)
→P. 2 8 0
■Emergency brake signal
In order to reduce the risk of a rear-end collision, when the brakes are
applied suddenly the stop lights will automatically flash to alert the vehicle
behind

■When the message is displayed on the multi-information display showing that
TRC has been disabled even if the VSC off switch has not been pressed
TRC and hill-start assist control cannot be operated. Contact your any authorized
Lexus dealer or repairer, or another duly qualified and equipped professional.
■Sounds and vibrations caused by the ABS, VSC, TRC and brake assist
●A sound may be heard from the engine compartment when the engine is
started or just after the vehicle begins to move. This sound does not indicate that
a malfunction has occurred in any of these systems.
●Any of the following conditions may occur when the above systems are operat-
ing. None of these indicates that a malfunction has occurred.
• Vibrations may be felt through the vehicle body and steering.
• A motor sound may be heard after the vehicle comes to a stop.
• The brake pedal may pulsate slightly after the ABS is activated.
• The brake pedal may move down slightly after the ABS is activated.
■EPS operation sound
When the steering wheel is operated, a motor sound (whirring sound) may be
heard. This does not indicate a malfunction.
■Reactivation of the TRC/VSC systems
Turning off the engine after turning off the TRC/VSC systems will automatically
reactivate them.
■Reactivation of the TRC system linked to vehicle speed
When only the TRC system is turned off, the TRC system will turn on when vehicle
speed increases. However, when both TRC and VSC systems are turned off, the
systems will not turn on even when vehicle speed increases.
■Reduced effectiveness of the EPS system
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, refrain from excessive
steering input or stop the vehicle and turn the engine off. The EPS system should
return to normal within 10 minutes.

Hill-start assist control
■Hill-start assist control can be operated when
●The shift lever is in a position other than P.
●The parking brake is not applied.
●The accelerator pedal is not depressed.
■Hill-start assist control
●While hill-start assist control is operating, the brakes remain automatically
applied after the driver releases the brake pedal. The stop lights and the high
mounted stoplight turn on.
●Hill-start assist control operates for about 2 seconds after the brake pedal is
released.
●If the slip indicator does not flash and the buzzer does not sound when the brake
pedal is further depressed, slightly reduce the pressure on the brake pedal (do
not allow the vehicle to roll backward) and then firmly depress it again. If the sys-
tem still does not operate, check if the operating conditions explained above
have been met.
Hill-start assist control helps to prevent the vehicle from rolling backwards
when starting on an incline or slippery slope.
To engage hill-start assist con-
trol, further depress the brake
pedal when the vehicle is
stopped completely.
A buzzer will sound once to
indicate the system is activated.
The slip indicator will also start
flashing.

CAUTION
■Roof luggage carrier precautions (if equipped)
To use the roof rails as a roof luggage carrier, you must fit the roof rails with two or
more genuine Lexus cross rails or their equivalent.
When you load cargo on the roof luggage carrier, observe the following:
●Before driving, make sure the cargo is securely fastened on the roof luggage car-
rier.
●Loading cargo on the roof luggage carrier will make the center of gravity of the
vehicle higher. Avoid high speeds, sudden starts, sharp turns, sudden braking or
abrupt maneuvers, otherwise the result may be a loss of control or vehicle roll-
over due to failure to operate this vehicle correctly and result in death or serious
injury.
●If driving for long distances, on rough roads, or at high speeds, stop the vehicle
now and then during the trip to make sure the cargo remains in its place.
●Do not exceed 75 kg (165 lb.) cargo weight on the roof luggage carrier.
NOTICE
■When loading cargo
Be careful not to scratch the surface of the moon roof.
●Place the cargo so that its weight is distrib-
uted evenly between the front and rear
axles.
●If loading long or wide cargo, never exceed
the vehicle’s overall length or width.
