come on when you start the hybrid sys-
tem, this could mean that these systems
are not available to he lp protect you in an
accident, which could result in death or
serious injury. Have the vehicle inspected
by your Lexus dealer immediately if this
occurs.

do not put the transmission in D.
( P.176)
Instability happens more frequently
when descending steep or long
downhill grades. Before descend-
ing, slow down and downshift. Do
not make sudden downshifts while
descending steep or long downhill
grades.
Avoid holding the brake pedal down
too long or applying the brakes too
frequently. This could cause the
brakes to overheat and result in
reduced braking efficiency.
Due to the added load of the trailer,
your vehicle’s engine may overheat
on hot days (at temperatures over
85°F [30°C]) when driving up a
long or steep grade. If the engine
coolant temperature gauge indi-
cates overheating, immediately turn
off the air conditioning (if in use),
pull your vehicle off the road and
stop in a safe spot. ( P.396)
Always place wheel blocks under
both the vehicle’s and the trailer’s
wheels when parking. Put the trans-
mission in P and apply the parking
brake. Avoid parking on a slope, but
if unavoidable, do so only after per-
forming the following:
1 Apply the brakes and keep them
applied.
2 Have someone place wheel blocks
under both the vehicle’s and trailer’s
wheels. 3
When the wheel blocks are in
place, release the brakes slowly
until the blocks absorb the load.
4 Shift into P and apply the parking
brake.
5 Turn off the hybrid system.
When restarting after parking on a
slope:
1 With the transmission in P, start the
hybrid system. Be sure to keep the
brake pedal depressed.
2 Shift into a forward gear. If revers-
ing, shift into R.
3 If the parking brake is in manual
mode, release the parking brake.
(P.178)
4 Release the brake pedal, and slowly
pull or back away from the wheel
blocks. Stop and apply the brakes.
5 Have someone retrieve the blocks.

WARNING
●Assisting the driver to measure follow-
ing distance
The dynamic radar cruise control with
full-speed range is only intended to
help the driver in determining the fol-
lowing distance between the driver’s
own vehicle and a designated vehicle
traveling ahead. It is not a mechanism
that allows careless or inattentive driv-
ing, and it is not a system that can assist
the driver in low-visibility conditions. It
is still necessary for driver to pay close
attention to the vehicle’s surroundings.
●Assisting the driver to judge proper
following distance
The dynamic radar cruise control with
full-speed range determines whether
the following distance between the
driver’s own vehicle and a designated
vehicle traveling ahead is within a set
range. It is not capable of making any
other type of judgement. Therefore, it
is absolutely necessary for the driver to
remain vigilant and to determine
whether or not there is a possibility of
danger in any given situation.
●Assisting the driver to operate the
vehicle
The dynamic radar cruise control with
full-speed range has limited capability
to prevent or avoid a collision with a
vehicle traveling ahead. Therefore, if
there is ever any danger, the driver
must take immediate and direct con-
trol of the vehicle and act appropri-
ately in order to ensure the safety of all
involved.
■To avoid inadvertent dynamic radar
cruise control with full-speed range
activation
Switch the dynamic radar cruise control
with full-speed rang e off using the “ON/
OFF” button when not in use.
■Situations unsuitable for dynamic
radar cruise control with full-speed
range
Do not use dynamic radar cruise control
with full-speed range in any of the follow-
ing situations.
Doing so may result in inappropriate
speed control and could cause an acci-
dent resulting in death or serious injury.
●Roads where there are pedestrians,
cyclists, etc.
●In heavy traffic
●On roads with sharp bends
●On winding roads
●On slippery roads, such as those cov-
ered with rain, ice or snow
●On steep downhills, or where there
are sudden changes between sharp up
and down gradients
Vehicle speed may exceed the set
speed when driving down a steep hill.
●At entrances to freeways and highways
●When weather conditions are bad
enough that they may prevent the sen-
sors from detectin g correctly (fog,
snow, sandstorm, heavy rain, etc.)
●When there is rain, snow, etc. on the
front surface of th e radar sensor or
camera sensor
●In traffic conditions that require fre-
quent repeated acceleration and
deceleration
●When your vehicle is towing a trailer
or during emergency towing
●When an approach warning buzzer is
heard often

■Sensor detectio n information
●The sensor’s detection areas are limited
to the areas around the vehicle’s bumper.
●Certain vehicle conditions and the sur-
rounding environment may affect the
ability of a sensor to correctly detect an
obstacle. Particular instances where this
may occur are listed below.
• There is dirt, snow or ice on the sensor. (Wiping the sensors will resolve this
problem.)
• The sensor is frozen. (Thawing the area will resolve this problem.)
In especially cold weather, if a sensor is
frozen the screen may show an abnormal
display, or obstacles may not be
detected.
• The sensor is covered in any way.
• The vehicle is leaning considerably to one side.
• On an extremely bumpy road, on an incline, on gravel, or on grass.
• The vicinity of the vehicle is noisy due to vehicle horns, motorcycle engines, air
brakes of large vehicles, or other loud
noises producing ultrasonic waves.
• There is another vehicle equipped with parking assist sensors in the vicinity.
• The sensor is coated with a sheet of spray or heavy rain.
• The vehicle is equipped with a fender
pole or wireless antenna.
• Towing eyelets are installed.
• The bumper or sensor receives a strong impact.
• A backlit license plate, license plate holder, etc., are installed.
• The vehicle is approaching a tall or curved curb.
• In harsh sunlight or intense cold weather.
• The area directly under the bumpers is
not detected.
• If obstacles draw too close to the sensor.
• A non-genuine Lexus suspension (low- ered suspension etc.) is installed.
• People may not be detected if they are wearing certain types of clothing.
In addition to the examples above, there are
instances in which, because of their shape,
signs and other objects may be judged by a
sensor to be closer than they are.
●The shape of the obstacle may prevent a sensor from detecting it. Pay particular
attention to the following obstacles:
• Wires, fences, ropes, etc.
• Cotton, snow and other materials that
absorb sound waves
• Sharply-angled objects
• Low obstacles
• Tall obstacles with upper sections pro- jecting outwards in the direction of your
vehicle
●The following situations may occur
during use.
• Depending on the shape of the obstacle and other factors, the detection distance
may shorten, or detection may be impos-
sible.
• Obstacles may not be detected if they
are too close to the sensor.
• There will be a short delay between obstacle detection and display. Even at
slow speeds, there is a possibility that the
obstacle will come within the sensor’s
detection areas befo re the display is
shown and the buzzer sounds.
• Thin posts or object s lower than the sen-
sor may not be detected when
approached, even if they have been
detected once.
• It might be difficult to hear beeps due to
the volume of audio system or air flow
noise of the air conditioning system.
