SWITCHING TO CONSTANT SPEED (CRUISE) CONTROL MODE
SETTING CONSTANT SPEED (CRUISE) CONTROL
Note: When your vehicle is too close to a vehicle ahead, and sufficient automatic
deceleration via the cruise control is not possible, the display will flash and the
buzzer will sound to alert the driver. An example of this would be if another driver
cuts in front of you while you are following a vehicle. Depress the brake pedal to
ensure an appropriate vehicle-to-vehicle distance.
If you are already using DRCC “,” push ON-OFF button to turn the system off
first, then push and hold ON-OFF button for at least 1.5 seconds to switch.
Note: When the engine is turned off, it will automatically default to DRCC.
(3) 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 system then
returns to constant speed cruising.
To adjust speed or cancel, see steps (2) and (3) of ADJUSTING SET SPEED on
page 43.
Refer to the Toyota Owner’s Manual for additional information on DRCC operation,
settings adjustments, limitations, and precautions before attempting to use it.

Road Sign Assist (RSA)
Road Sign Assist is designed to help ensure drivers are kept informed. The RSA
system recognizes specific road signs using a forward-facing camera and/or
navigation system to provide information to the driver via a Multi-information Display
(MID). If the system judges that the vehicle is being driven over the speed limit, or
performing actions prohibited by other support types of road signs, it notifies the
driver using a notification display and notification buzzer.

When the driving assist system
information is selected, a maximum of
2 signs can be displayed.

When a tab other than the driving assist
system information is selected, the
following types of road signs will be
displayed.
• Speed limit sign
• Do Not Enter sign (when notification
is necessary)
(1) Press “ ” switches and select “” from the Multi-Information Display (MID).
(2) Press “ ” switches and select the “” setting function and then press “.”
(3) Press “” each time to change the setting.
(4) Press “” to go back to the menu.
Note: If the engine switch was last turned off while a speed limit sign was
displayed on the multi-information display, the same sign displays again when
the engine switch is turned back ON.
Refer to the Toyota Owner’s Manual for additional information on RSA operation,
settings adjustments, limitations, and precautions before attempting to use it.

SMART STOP TECHNOLOGY (SST)
Star Safety System™
Smart Stop Technology automatically reduces engine power when the accelerator
and brake pedals are pressed simultaneously under certain conditions.
SST engages when the accelerator is depressed first and the brakes are applied
firmly for longer than one-half second at speeds greater than five miles per hour.
SST doesn’t engage if the brake pedal is depressed before the accelerator pedal,
allowing vehicles to start on a steep hill and safely accelerate without rolling
backward.
Refer to the Brake Override System section in the Owner’s Manual for more
information on Smart Stop Technology.
ENHANCED VEHICLE STABILITY CONTROL (VSC)
Enhanced Vehicle Stability Control provides cooperative control of the ABS, TRAC,
VSC and EPS.
Enhanced VSC helps to maintain directional stability when loss of traction occurs
during a turn.
ANTI-LOCK BRAKE SYSTEM (ABS)
Toyota’s ABS sensors detect which wheels are locking up and limits wheel lockup
by “pulsing” each wheel’s brakes independently. Pulsing releases brake pressure
repeatedly for fractions of a second. This helps the tires attain the traction that
current road conditions will allow, helping you to stay in directional control.
BRAKE ASSIST (BA)
Brake Assist is designed to detect sudden or “panic” braking, and then add braking
pressure to help decrease the vehicle’s stopping distance. When there’s only a split
second to react, Brake Assist can add additional brake pressure more quickly than
just the driver alone can.
ELECTRONIC BRAKE FORCE DISTRIBUTION (EBD)
Toyota’s ABS technology has Electronic Brake-force Distribution (EBD) to help
maintain control and balance when braking. EBD responds to sudden stops by
redistributing brake force to enhance the braking effectiveness of all four wheels.
Your vehicle comes standard with the Star Safety SystemTM, which combines Anti-
lock Braking System (ABS), Brake Assist (BA), Electronic Brake-force Distribution
(EBD), Smart Stop Technology (SST), Traction Control (TRAC) and Vehicle Stability
Control (VSC).
Refer to the Owner’s Manual for more details and important information on limitations
to these systems.
