■Automatic cancelation of c onstant speed control mode
Constant speed control mode is automatically canceled in the following situa-
tions:
● Actual vehicle speed is more than approximately 10 mph (16 km/h ) below
the set vehicle speed.
● Actual vehicle speed falls below approximately 25 mph (40 km/h) .
● VSC is activated.
● Active TRAC is activated for a period of time.
● When the VSC or Active TRAC system is turned off.
● Pre-collision braking is activated.
● The center differential lock/unlock is not completed within 5 s econds while
the cruise control system is on.
If constant speed control mode is automatically canceled for an y other rea-
son, there may be a malfunction in the system. Contact your Toyota dealer.
■ Brake system operation sound
If the brakes are applied automatically while the vehicle is in vehicle-to-vehi-
cle distance control mode, a brake system operation sound may b e heard.
This does not indicate a malfunction.
■ Warning messages and buzzers for d ynamic 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. If a warning message
is shown on the multi-information display, read the message and follow the
instructions.
■ When the sensor may not be correctly detect ing the vehicle ahead
In the case of the following and depending on the conditions, o perate the
brake pedal when deceleration of the system is insufficient or operate the
accelerator pedal when acceleration is required.
As the sensor may not be able to correctly detect these types o f vehicles, the
approach warning ( P. 280) may not be activated.
● Vehicles that cut in suddenly
● Vehicles traveling at low speeds
● Vehicles that are not moving in the same lane
● Vehicles with small rear ends (trailers with no load on board, etc.)
● Motorcycles traveling in the same lane

■Automatic cruise co ntrol cancelation
Cruise control will stop maintaining the vehicle speed in any o f the following
situations:
● Actual vehicle speed falls more than approximately 10 mph (16 k m/h) below
the preset vehicle speed.
At this time, the memorized set speed is not retained.
● Actual vehicle speed is below approximately 25 mph (40 km/h).
● VSC is activated.
● The center differential lock/unlock is not completed within 5 s econds while
the cruise control system is on.
● Active TRAC is activated for a period of time.
● When the VSC or Active TRAC system is turned off.
■ If “Cruise Control Malfunction Vi sit Your Dealer” is shown on the multi-
information display
Press the “ON-OFF” button once to deactivate the system, and th en press
the button again to reactivate the system.
If the cruise control speed cannot be set or if the cruise cont rol cancels imme-
diately after being activated, there may be a malfunction in th e cruise control
system. Have the vehicle inspected by your Toyota dealer.
WARNING
■ To avoid operating the cruise control by mistake
Switch the cruise control off using the “ON-OFF” button when not in use.
■ Situations unsuitable for cruise control
Do not use cruise control in any of the following situations.
Doing so may result in loss of control and could cause an accid ent 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 hills
Vehicle speed may exceed the set speed when driving down a stee p hill.
● When your vehicle is towing a trailer (with towing hitch) or du ring emer-
gency towing

Lock the center differential when
your vehicle’s wheels get stuck in
a ditch or when driving on a slip-

■The four-wheel drive control sw itch can be operated when
● The engine switch is in IGNITION ON mode.
● The shift lever is in the N position.
● The vehicle is stopped completely.
■ The low speed four-whee l 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 t raction 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 switch is in IGNITION ON mode.
● The vehicle speed is less than 62 mph (100 km/h).
■ Locking/unlocking the center differential
●When the four-wheel drive control switch is in L4 with the cent er differential
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 dri ve 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.
■ If the low speed four-wheel drive indicator light or the center differential
lock indicator light blinks
● If the low speed four-wheel drive indicator light continues to blink when
using the four-wheel drive control switch, stop the vehicle completely, move
the shift lever to N and operate the switch again.
● If the shift lever is moved before the low speed four-wheel dri ve indicator
turns on/off, the transfer mode may not be shifted completely. The transfer
mode disengages both the front and rear driveshafts from the po wertrain
and allows the vehicle to move regardless of the shift position. (At this time,
the indicator blinks and the buzzer sounds.)
Therefore, the vehicle is free to roll even if the automatic tr ansmission is in
P. You or someone else could be seriously injured. You must com plete the
shifting of the transfer mode.
To complete the shifting, stop the vehicle completely, return the shift lever to
N, and confirm that the shift was completed (the indicator turn s on/off).

●If the engine coolant temperature is too low, the four-wheel dr ive control
system may not be able to shift. When the engine is warmer pres s the
switch again.
If the low speed four-wheel drive indicator light or the center differential lock
indicator light continues to blink even after attempting the ab ove, there may
be a malfunction in the engine, the brake system or the four-wh eel drive sys-
tem. In this case, you may not be able to shift between H4 and L4, and the
center differential lock may not be operable. Have the vehicle inspected by
your Toyota dealer immediately.
WARNING
■ While driving
Never move the four-wheel drive control switch if the wheels ha ve lost trac-
tion. Doing so may cause an accident resulting in death or serious injury.
■ When the vehicle is parked
If the shift lever is moved before the low speed four-wheel dri ve indicator
turns on/off, the transfer mode may not be shifted completely. The transfer
mode disengages both the front and rear driveshafts from the po wertrain
and allows the vehicle to move regardless of the shift position . (At this time,
the indicator blinks and the buzzer sounds.)
Therefore, the vehicle is free to roll even if the automatic tr ansmission is in
P. You or someone else could be seriously injured. You must com plete the
shifting of the transfer mode.
NOTICE
■ To prevent damage to the center differential
● For normal driving on dry and hard surface roads, unlock the ce nter differ-
ential.
● Unlock the center differential after the wheels are out of the ditch or off the
slippery or bumpy surface.
● Do not push the center differential lock/unlock switch when the vehicle is
turning or when its wheels are spinning freely off the ground.
