■Automatic cancelation of constant speed control
The cruise control will stop maintaining the vehicle speed in the following sit-
uations:
●Actual vehicle speed is more than approximately 10 mph (16 km/h)
below the set vehicle speed.
At this time, the memorized set speed is not retained.
● Actual vehicle speed falls below approximately 25 mph (40 km/h).
● VSC is activated.
● The switching operation continues for 5 seconds or more after the center
differential lock switch has been operated.
■ Radar sensor and grille cover
Always keep the sensor and grille cover clean to ensure that the vehicle-t\
o-
vehicle distance control operates properly. (Some obstructions, such as
snow, ice and plastic objects, cannot be detected by the obstruction sensor.)
Dynamic radar cruise control is canceled if an obstruction is detected.
■ Warning messages and bu zzers for dynamic radar cruise control
Warning messages and buzzers are used to indicate a system malfunction
or to inform the driver of the need for caution while driving. ( P. 625)

CAUTION
■Before using dynamic radar cruise control
Do not overly rely on vehicle-to-vehicle distance control.
Be aware of the set speed. If automatic deceleration/acceleration is not
appropriate, adjust the vehicle speed, as well as the distance between your
vehicle and vehicles ahead by applying the brakes, etc.
■ Cautions regarding the driving assist systems
Observe the following precautions.
Failure to do so may cause an accident resulting in death or serious injury.
●Assisting the driver to measure following distance
The dynamic radar cruise control is only intended to help the driver in
determining the following distance between the driver’s own vehicle and a
designated vehicle traveling ahead. It is not a mechanism that allows care-
less or inattentive driving, 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 determines whether the following dis-
tance between the driver’s own vehicle and a designated vehicle traveling
ahead is appropriate or not. 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 has no capability to prevent or avoid a
collision with a vehicle traveling ahead. Therefore, if there is ever any dan-
ger, the driver must take immediate and direct control of the vehicle and
act appropriately in order to ensure the safety of all involved.
■ To avoid inadvertent cruise control activation
Switch the cruise control off using the “ON-OFF” button when not in use.

CAUTION
■Situations unsuitable for dynamic radar cruise control
Do not use dynamic radar cruise control in any of the following situations.
Doing so may result in inappropriate speed control and could cause an acci-
dent resulting in death or serious injury.
●In heavy traffic
● On roads with sharp bends
● On winding roads
● On slippery roads, such as those covered 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 expressways
● When weather conditions are bad enough that they may prevent the sen-
sors from functioning correctly (fog, snow, sandstorm, heavy rain etc.)
● When an approach warning buzzer is heard often
● When your vehicle is towing a trailer or during emergency towing

CAUTION
■Handling the radar sensor
Observe the following to ensure the cruise control system can function effec-
tively.
Otherwise, the system may not function correctly and could result in an acci-
dent.
●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 Toyota dealer.
● Do not disassemble the sensor.
● Do not attach accessories or stickers to the sensor, grille cover or sur-
rounding area.
● Do not modify or paint the sensor and grille cover.
● Do not replace them with non-genuine parts.

■The four-wheel drive control switch can be operated when
●The “ENGINE START STOP” switch is in IGNITION ON mode.
● The shift lever is in the “N” position.
● The vehicle is stopped completely.
■ The low speed four-wheel drive indicator light
The indicator light blinks while shifting between “H4” and “L4”.
■ Advice for driving on slippery roads
●If you shift the four-wheel drive control switch to “L4” and the shift lever to
the “2” range of “S” while driving in steep off-road areas, the output of the
brake can be controlled effectively by the Active TRAC, which assists the
driver to control the driving power of 4 wheels.
● Use the “1” range of “S” of the shift lever for maximum power and traction
when your wheels get stuck or when driving down a steep incline.
■ The center differential lock indicator light
The indicator light blinks while locking/unlocking the center differential.
■ The center differential lock/unlock switch can be operated when
●The “ENGINE START STOP” switch is in IGNITION ON mode.
● The vehicle speed is less than 60 mph (100 km/h).
■ Locking/unlocking the center differential
● When the four-wheel drive control switch is in L4 with the center differen-
tial locked, VSC is automatically turned off. (The center differential lock
and VSC OFF indicator lights come on.)
● If the operation is not completed, the center differential lock indicator
blinks. If the indicator light does not turn off when unlocking the center
differential, drive straight ahead while accelerating or decelerating, or
drive in reverse.
● If the center differential lock/unlock is not completed within 5 seconds
while the cruise control system is on, cancel the cruise control system.

CAUTION
■To avoid accident or injury
●Do not exceed the trailer hitch assembly weight, gross vehicle weight,
gross axle weight and trailer tongue weight capacities.
● Do not use cruise control when towing.
● Slow down and downshift before descending steep or long downhill
grades. Do not make sudden downshifts while descending steep or long
downhill grades.
● Vehicle-trailer instability is more likely on steep long down hills. Before
descending steep or long downhill grades, slow down and downshift. Do
not make sudden downshifts when 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.
■ Hitch
Trailer hitch assemblies have different weight capacities established by the
hitch manufacturer. Even though the vehicle may be physically capable of
towing a higher weight, the operator must determine the maximum weight
rating of the particular hitch assembly and never exceed the maximum
weight rating specified for the trailer-hitch. Exceeding the maximum weight
rating set by the trailer-hitch manufacturer can cause an accident resulting in
death or serious personal injuries.
■ When towing a trailer
Toyota recommends trailers with brakes that conform to any applicable fed-
eral and state/provincial regulations.
●If the gross trailer weight exceeds unbraked TWR, trailer brakes are
required. Toyota recommends trailers with brakes that conform to all appli-
cable federal and state/provincial regulations.
● Never tap into your vehicle’s hydraulic system, as this will lower the vehi-
cle’s braking effectiveness.
● Never tow a trailer without using a safety chain securely attached to both
the trailer and the vehicle. If damage occurs to the coupling unit or hitch
ball, there is danger of the trailer wandering into another lane.
