Example of constant speed cruising
When there are no vehicles ahead
The vehicle travels at the speed set by the driver. The desired vehicle-to-
vehicle distance can also be set by operating the vehicle-to-ve hicle dis-
tance switch.
Example of deceleration crui sing and follow-up cruising
When a preceding vehicle driving slower than the set speed
appears
When a vehicle is detected running ahead of you, the system automatically
decelerates your vehicle. When a greater reduction in vehicle s peed is
necessary, the system applies the brakes (the stop lights will come on at
this time). The system will respond to changes in the speed of the vehicle
ahead in order to maintain the vehicle-to-vehicle distance set by the driver.
Approach warning warns you when the system cannot decelerate su ffi-
ciently to prevent your vehicle from closing in on the vehicle ahead.
Example of acceleration
When there are no longer any preceding vehicles driving slower
than the set speed
The system accelerates until the set speed is reached. The syst em then
returns to constant speed cruising.

WARNING
■Sensor detection information
Pay particular attention to the following instances in where th is may occur.
Failing to do so way result in the vehicle being unable to be d riven or parked
safety and possibly cause an accident.
● The sensor’s detection areas are limited to the areas around the vehicle’s
rear bumper.
● Certain vehicle conditions and the surrounding environment may affect the
ability of the sensor to correctly detect obstacles. 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 prob lem.)
• 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 gr ass.
• 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 radio antenna.
• The bumper or sensor receives a strong impact.
• 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 Toyota suspension (lowered suspension, etc.) is installed.
• A backlit license plate, license plate holder, etc., are installed.
• People may not be detected if they are wearing certain types a nd color-
ing of clothing.
• People, animals, and moving objects may not be able to be detected.
In addition to the examples above, there are instances in which , because of
their shape, signs and other objects may be judged by the senso r to be
closer than they are.

The Blind Spot Monitor function uses radar sensors to detect ve hicles
that are traveling in an adjacent lane in the area that is not reflected in
the outside rear view mirror (the blind spot), and advises the driver of
the vehicles existence via the outside rear view mirror indicat o r.
WARNING
■Handling the radar sensor
One Blind Spot Monitor sensor is installed inside the left and right side of
the vehicle rear bumper respectively. Observe the following to ensure the
Blind Spot Monitor system can function correctly.
● Do not subject the sensor or surrounding area on the bumper to a strong
impact. If the sensor moves even slightly off position, the system may mal-
function and vehicles that enter the detection area may not be detected. If
the sensor or surrounding area is subject to a strong impact, always have
the area inspected by your Toyota dealer.
● Do not disassemble the sensor.
● Do not attach accessories or stickers to the sensor or surrounding area on
the bumper.
● Do not modify the sensor or surrounding area on the bumper.
● Do not paint the rear bumper any color other than an official Toyota color.
The Blind Spot Monitor function
●Keep the sensor and its surrounding
area on the bumper clean at all times.

●Shifting to “4H” or “4L”
Automatic transmission
If the “4LO” indicator continues to blink when you operate the front-wheel
drive control switch to the “4H” or “4L” position, drive forwar d or backward
in a short distance, then stop the vehicle completely, shift th e shift lever
securely to N and operate the switch again.
Manual transmission
If the “4LO” indicator continues to blink when you operate the front-wheel
drive control switch to the “4H” or “4L” position, drive forwar d or backward
in a short distance, then stop the vehicle completely, depress the clutch
pedal and operate the switch again.
If the indicator light continues to blink even if doing so, contact your Toyota
dealer as soon as possible. There may be a trouble in the four- wheel drive
system.
■ Shifting to “4L”
VSC is automatically turned off.
■ Four-wheel drive usage frequency
You should drive in four-wheel drive for at least 10 miles (16 km) each month.
This will assure that the front drive components are lubricated.
WARNING
■Caution while driving
● Never shift the front-wheel drive control switch from “2WD” to “4H” if the
wheels are slipping.
Stop the slipping or spinning before shifting.
● For normal driving on dry and hard surface roads, use “2WD” pos ition.
Driving on dry and hard surface roads in “4H” or “4L” position may cause
drive component oil leakage, seizure, or other problems resulti ng in an
accident. Further, it may cause tire wear and increased fuel consumption.
● Avoid turning suddenly in “4H” or “4L” position. If you do turn suddenly, the
difference in turning speeds between the front and rear wheels may have
a similar effect to braking, thus making driving difficult.
● Do not shift the front-wheel drive control switch when the vehicle is turning
or when its wheels are spinning freely off the ground.
