Q Automatic cancelation of constant speed control mode
Constant speed control mode is automatically canceled in the following situa-
tions:
O Actual vehicle speed is more than approximately 16 km/h (10 mph) below
the set vehicle speed.
O Actual vehicle speed falls below approximately 30 km/h (20 mph).
O VSC is activated.
O TRC/A-TRC is activated for a period of time.
O When the VSC or TRC/A-TRC system is turned off.
O When the brake control or output restriction control of a driving support sys-
tem operates. (For example: Pre-Coll ision System, Drive-Start Control)
O When the shift lever is in N or the clutch pedal is depressed for a certain
amount of time or more. (Vehicles with manual transmission)
O 4WD models: Switching the transfer mode is not completed within 5 sec-
onds while the cruise control system is on.
If constant speed control mode is automatically canceled for any reasons
other than the above, there may be a malfunction in the system. Contact any
authorized Toyota retailer or Toyota authorized repairer, or any reliable
repairer.
Q The Dynamic Radar Cruise Control with Road Sign Assist may not oper-
ate properly when
As the Dynamic Radar Cruise Control with Road Sign Assist may not oper-
ate properly in conditions in which RSA may not operate or detect correctly
( P. 299), when using this function, make sure to check the speed limit
sign displayed.
In the following situations, the set speed may not be changed to the recog-
nized speed limit by pushing the lever up or down.
O If speed limit information is not available
O When the recognized speed limit is the same as the set speed
O When the recognized speed limit is outside of the speed range that the
dynamic radar cruise control system can operate
Q Brake operation
A brake operation sound may be heard and the brake pedal response may
change, but these are not malfunctions.
Q Warning messages and buzzers 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. If a warning message
is shown on the multi-information display, read the message and follow the
instructions. ( P. 271, 575)

Four-wheel drive system
H2 (high speed position, two-
wheel drive)
Use this for normal driving on dry
hard-surfaced roads. This position
gives greater economy, quietest
ride and least wear.
H4 (high speed position, four-
wheel drive)
Use this for driving only on tracks
that permit the tires slide, like off-
road, icy or snow-covered roads.
This position provides greater trac-
tion than two-wheel drive.
The four-wheel drive indicator
light comes on
L4 (low speed position, four-
wheel drive)
Use this for maximum power and traction. Use L4 for climbing or descend-
ing steep hills, off-road driving, and hard pulling in sand, mud or deep
snow.
The four-wheel drive and low speed four-wheel drive indicator lights
come on
The A.D.D. can be engaged or disengaged by the shifting operations
described in the following shifting procedures.
: If equipped
Use the front-wheel drive control switch to select the following
transfer modes.

When the engine is stopped by the Stop & Start system when the
vehicle is on an incline, when the brake pedal is released, brake force
is temporarily maintained to prevent the vehicle from rolling back-
wards before the engine is restarted and drive force is generated.
When drive force is generated, the maintained brake force is automat-
ically canceled.
O This function operates on flat surfaces as well as steep inclines.
O Sound may be generated from the brake system, but this does not
indicate a malfunction.
O Brake pedal response may change and vibration may occur, but
this does not indicate a malfunction.
Q Points for use
O If the engine switch is pressed when the engine is stopped by the Stop &
Start system, the engine will not be able to be restarted by the automatic
engine start function. In this case, restart the engine using the normal
engine starting procedure. ( P. 220, 223)
O When the engine is being restarted by the Stop & Start system, the power
outlets may be temporarily unusable, but this does not indicate a malfunc-
tion.
O Installation and removal of electrical components and wireless devices may
affect the Stop & Start system. Contact any authorized Toyota retailer or
Toyota authorized repairer, or any reliable repairer for details.
O When stopping the vehicle for a longer period of time, turn the engine switch
to the “LOCK” position*1 or off*2 to stop the engine completely.
O When the engine is restarted by the Stop & Start system, the steering wheel
may temporarily feel heavy.
O 4WD models only: While driving in L4 mode, it is recommended that the
Stop & Start system be canceled because the system may not operate prop-
erly.

system and the shift lever is in D, a buzzer will sound and the Stop & Start
system indicator will flash. To stop the buzzer, close the driver’s door.
Q The Stop & Start system protection function
O When the volume of the audio system is excessively high, sound output
from the audio system may suddenly be cut off in order to reduce battery
consumption. To prevent the audio system from being cut off, keep the vol-
ume of audio system at a moderate level. If the audio system has been cut
off, turn the engine switch to the “LOCK” position*1 or off*2, wait for 3 sec-
onds or more and then turn it to the “ACC” position*1 or ACCESSORY
mode*2 or the “ON” position*1 or IGNITION ON mode*2 to re-enable the

QOperating tips (vehicles with automatic transmission)
The system will operate when the shift lever is in a position other than P, how-
ever to make effective use of the system it is recommended to select a lower
shift range.
Q The system will not operate when
O The transfer mode is in H2.
O The rear differential is locked. (if equipped)
Q If the downhill assist control system indicator flashes
O In the following situations, the indicator flashes and the system will not oper-
ate:
• The transfer mode is not in L4 or H4.
• The rear differential is locked. (if equipped)
• The shift lever is in P. (vehicles with automatic transmission)
• The accelerator or brake pedal is depressed.
• The vehicle speed exceeds approximately 30 km/h (18 mph).

• The “DAC” switch is turned off while the system is operating.
The system will gradually ceases operat ion. The indicator will flash during
operation, and then go off when the system is fully off.
Q When the downhill assist control system is operated continuously
This may cause the brake actuator to overheat. In this case, the downhill
assist control system will stop operating, a buzzer will sound and the downhill
assist control system indicator will start flashing, and “TRC turned off” will be
shown on the multi-information display. Refrain from using the system until
the downhill assist control system indicator stays on and the message goes
off. (The vehicle can be driven normally during this time.)

This format compresses audio data to a size smaller than that of the MP3 for-
mat.
AAC is short for Advanced Audio Coding and refers to an audio compression
technology standard used with MPEG2 and MPEG4.
There is a limit to the MP3, WMA and AAC file standards and to the media/
formats recorded by them that can be used.
