CAUTION
■When using the rear view monitor system, observe these 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.
●Depicted distances between objects and flat surfaces differ from actual dis-
tances.
●Do not use the system if the trunk is open.
■Conditions which may affect the rear view monitor system
●If the back of the vehicle is hit, the camera’s position and mounting angle may
change. See your Lexus dealer.
●Rapid temperature changes, such as when hot water is poured on the vehicle in
cold weather, may cause the system to function abnormally.
●If the camera lens is dirty, it cannot transmit a clear image. Rinse with water and
wipe with a soft cloth. If extremely dirty, wash with a mild cleanser and rinse.
●The displayed image may be darker and mo ving images may be slightly distorted
when the system is cold.

You can still use the accelerato r with the cruise control on.
■Set the vehicle speed
Turn the ON-OFF switch ON.
Push the button once more to
deactivate cruise control.
Accelerate or decelerate to the
desired speed and press the lever
down to set.
The speed must be above 25 mph
(40 km/h).

2-4. Using other driving systems
■Automatic cruise control cancellation
Cruise control is automatically cancelled
in any of the following situations.
• Actual vehicle speed is more than 10 mph
(16 km/h) below the preset vehicle
speed.
• Vehicle speed is less than 25 mph (40 km/h).
• The slip indicator light blinks and a warning tone sounds.
■If the cruise control indicator light flashes
Turn the ON-OFF switch off once, and then reactivate the system. There may be a
malfunction in the cruise control system if the indicator light does not come on,
flashes again or goes out after it comes on. Have the vehicle inspected by your
Lexus dealer.
CAUTION
■To avoid inadvertent cruise control activation
Keep the ON-OFF switch off when not in use.
■Locations unsuitable for cruise control
●Do not use cruise control in any of the following situations. 
Doing so may result in control of the v
ehicle being lost and may cause an acci -
dent.
• In heavy traffic.
• On roads with sharp bends.
• On slippery roads, such as th o
se covered with ice or snow.
• On steep hills.
• On winding roads.

When driving
Dynamic radar/ laser cruise control
The vehicle-to-vehicle distance control mode allows the vehicle to follow
another vehicle, adjusting to the leading vehicle’s speed variations, and the
conventional cruise control mode allows for driving at a preset speed, both
without the need to press the accelerator pedal.
■ Selecting a cruise control mode
Selecting the vehicle-to-vehicle
distance contr
ol mode
Turn the ON-OFF switch ON
Push the main switch again to turn
off the system.
Selecting the conventional cruise
control mode Turn the ON-OFF switch ON
Push and hold the lever for more
than one second.
Change to the conventional
cruise mode
The system is set to the vehicle-to-
vehicle distance control mode
each time the ignition is turned
ON.

When driving
Cruising in the vehicle-to-vehicle distance control mode
The system employs a millimeter radar or laser radar sensor affixed in the
front end to detect the pr esence of a vehicle ahead as well as measuring
the distance from your vehicle. The detection range of the sensor is
approximately 400 ft. (120 m) ahead. Vehicle-to-vehicle distance will be
less than the selected distance during long downhill driving.
Fixed speed cruising:
If no vehicle is detected ahead.
Deceleration cruising:
If a slower moving vehicle is
detected ahead, your vehicle
decelerates automatically. Your
vehicle applies the brakes if
required, and “BRAKE” is dis -
played on the multi-information
displa
y. A warning buzzer will
sound if your vehicle gets too close
to the vehicle ahead due to insuffi -
cient braking.
Follow-up cruising:
If the vehicle ahead is traveling
slower than the preset speed, your
vehicle continually adjusts its speed
to maintain the preset following
distance.
Acceleration cruising:
When the vehicle ahead changes
lanes, your vehicle will gradually
accelerate up to the preset speed,
and resume fixed speed cruising.

■Setting vehicle speed
Settings can be made when the vehicle
is traveling above 28 mph (45 km/h).
■Unsuitable conditions
You cannot set the speed in the following conditions:
• When the selector lever is in a position other than D, 4, 5, or 6.
• When driving in adverse weather conditions.
■Automatic cruise control cancellation
In the following cases, the preset speed is can ce
lled. If the system is restored, cruise
control enters the ready mode.
• The slip indicator light blinks and a warning tone sounds.
• The anti-lock braking system activates.
• Foreign matter adheres to the sensor.
• The driving pattern selector sw it
ch is set to “SNOW” mode.
• The wipers are operated at high speed (radar), or either high or low speeds (l
aser). This includes high and low speed operation with the wiper lever in the
AUTO position.
• The vehicle’s speed falls below 25 mph (40 km/h). In this case, you must apply th
e brakes manually to slow the vehicle.
If the preset speed automatically cancels out for other than the above reasons, the
sy

stem may have malfunctioned. Do not operate the dynamic radar/laser cruise
control. You may continue driving, howe ver have your vehicle checked by your
Lexus dealer at the earliest opportunity.

■Vehicle-to-vehicle distances
Select a vehicle-to-vehicle distance appropriate
to traffic conditions. The approxi-
mate vehicle-to-vehicle distance based on time interval when driving at 55 mph
(88 km/h) is sho

wn below:
If the vehicle speed is slower than 55 mph (88 km/h), the distance will be shorter
than ab
ove.
■Millimeter wave radar lase r sensor/ Laser radar sensor
The radar or laser sensor automatically detects dirt on the sensor or grill cover
(r
adar cruise control), or the sensor glass (laser cruise control). If dirt is detected, a
message is displayed on the multi-informatio n display, and the radar or laser cruise
control function is automatically cancelled.
