1702-1. Driving procedures
CAUTION●
Do not shift the shift lever to R while the vehicle is moving forward.
Doing so can damage the transmission and may result in a loss of vehicle control.●
Do not shift the shift lever to D while the vehicle is moving backward.
Doing so can damage the transmission and may result in a loss of vehicle control.●
Moving the shift lever to N while the vehicle is moving will disengage the hybrid
system. Engine braking is not availabl e with the hybrid system disengaged.●
During normal driving, do not turn off the hybrid system. Turning the hybrid sys-
tem off while driving will not cause loss of steering or braking control, however,
power assist to the steering will be lost. This will make it more difficult to steer
smoothly, so you should pull over and stop the vehicle as soon as it is safe to do so.
In the event of an emergency, such as if it becomes impossible to stop the vehicle
in the normal way:  P. 7 9 5●
Use engine braking (downshift) to maintain a safe speed when driving down a
steep hill.
Using the brakes continuously may cause the brakes to overheat and lose effec-
tiveness. (  P. 1 8 6 )●
When stopped on an incline, use the brake pedal and parking brake to prevent
the vehicle from rolling backward or forward, causing an accident. ●
Do not adjust the position of the steering wheel, the seat, or the inside or outside
rear view mirrors while driving.
Doing so may result in a loss of vehicle control that can cause accidents, resulting
in death or serious injury.●
Always check that all passengers' arms, heads or other parts of their body are not
outside the vehicle, as this may result in death or serious injury.●
Do not drive in excess of the speed limit. Even if the legal speed limit permits it, do
not drive over 85 mph (140 km/h) unless your vehicle has high-speed capability
tires. Driving over 85 mph (140 km/h) may result in tire failure, loss of control and
possible injury. Be sure to consult a tire dealer to determine whether the tires on
your vehicle are high-speed capability tires or not before driving at such speeds.

When driving CAUTION■
Conditions under which the vehicle-to-vehicle distance control may not function
correctly
Apply the brakes as necessary in the foll owing conditions as the radar sensor may
not be able to correctly detect vehicles ahead, and a fatal or serious accident may
result: ●
When water or snow thrown up by the surrounding vehicles hinders the function-
ing of the sensor●
When your vehicle is pointing upwards (caused by a heavy load in the luggage
compartment etc.)●
When the road curves or when the lanes are narrow●
When steering wheel operation or your position in the lane is unstable●
When the vehicle ahead of you decelerates suddenly■
Handling the radar sensor
Observe the following to ensure the cruise control system can function effectively.
Otherwise, the system may not function co rrectly and could result in an accident.●
Keep the sensor and grille cover clean at all times.
Clean the sensor and grille cover with a soft cloth so you do not mark or damage
them.●
Do not subject the sensor or surrounding area to a strong impact.
If the sensor moves even slightly off position, the system may malfunction. If the
sensor or surrounding area is subject to a strong impact, always have the area
inspected and adjusted by your Lexus dealer.●
Do not disassemble the sensor.●
Do not attach accessories or stickers to the sensor, grille cover or surrounding
area.
●
Do not modify or paint the sensor and grille cover.
●
Do not replace them with non-genuine parts.

■
Flicker effect
When the camera is used under fluorescent light, sodium lights, or mercury lights
etc., the lights and the illuminated areas may appear to flicker.
CAUTION■
When using the rear view monitor system, observe the following precautions to
avoid an accident that could result in death or serious injuries: ●
Never depend solely on the monitor system when reversing.●
Always check visually and with the mirrors to confirm your intended path is clear.●
Use your own eyes to confirm the vehicle’s surroundings, as the displayed image
may become faint or dark, and moving imag es will be distorted, or not entirely
visible when the outside temperature is low. When backing up, be sure to check
behind and all around the vehicle visually and with the mirrors before proceeding.●
Always check the vehicle surrounding area, because the guide lines are ancillary
lines.●
The guide lines are ancillary lines and do not change even if the steering wheel is
turned.●
Depicted distances between objects and flat surfaces differ from actual dis-
tances.●
Do not use the system if the back door is open.

When driving 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
■ TRAC (Traction Control) Helps to maintain drive power and prevent the drive wheels from spinning
when starting the vehicle or accelerating on slippery roads
■ Hill-start assist control  P. 2 76
■ EPS (Electric Power Steering) Employs an electric motor to reduce the amount of effort needed to turn
the steering wheel
■ VDIM (Vehicle Dynamics Integrated Management) 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 sur-
faces by controlling the brakes and hybrid system output.
■ PCS (Pre-Collision System) (if equipped)
 P. 2 7 8
■ BSM (Blind Spot Monitor) (if equipped)
 P. 2 8 6

2722-4. Using other driving systems
When the VSC/TRAC systems are operating
If the vehicle is in danger of slip-
ping or if any of the drive wheels
spins, the slip indicator light flashes
to indicate that the VSC/TRAC
systems are operating.
Disabling TRAC and/or VSC systems
If the vehicle gets stuck in fresh snow or mud, the TRAC/VSC systems
may reduce power from the hybrid system to the wheel s. You may need
to turn the system off to enable you to rock the vehicle in order to free it.
■ Turning off the TRAC system only
To turn the TRAC system off,
quickly press and release the
switch. A message will be shown on the
multi-information display.
Press the switch again to turn the
system back on.
