The set speed may also be cancelled by depressing the brake pedal.

The set speed may be resumed once vehicle speed exceeds 25 mph.
DRCC helps maintain a pre-set distance to a preceding vehicle when the preceding
vehicle is traveling at a lower speed. This mode is always selected first when the
cruise control button is depressed. Constant speed cruise control mode is also
available. DRCC is designed to function at speeds between approximately 30 to
110 MPH and is intended for highway use. Full-Speed Range DRCC is designed
to function at speeds between 0 to approximately 110 MPH and is intended for
highway use.
Refer to page 41 for switching to Constant Speed (Cruise) Control Mode.
Vehicle will cruise at a set speed, decelerate to maintain selected distance from a
slower vehicle traveling in front and accelerate back up to the selected speed if the
vehicle in front changes lanes or speeds up.

(1) Push the ON-OFF button. The “RADAR READY” or “
” indicator will come on.
(2) Push the lever down to SET speed, push it up to Resume and pull it or depress brake to Cancel.
(3) Push up to increase the set speed, push down to decrease (1 mph [1.6 km/h] or 1 km/h [0.6 mph] increments).

ADJUSTING DISTANCE
To change the vehicle-to-vehicle distance

Push the “
” button to cycle
through the settings, which will
change progressively.
This mode employs a radar sensor to detect the presence of a preceding vehicle
up to approximately 328 ft (100 m) ahead, determines the current vehicle-to-vehicle
following distance and operates to maintain a preset following distance from the
vehicle ahead. These distances vary based on vehicle speed.

(1) 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-vehicle distance
control.
(2) Deceleration cruising 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 speed is
necessary, the system applies the brakes (the brake 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. A warning
tone warns you when the system cannot decelerate sufficiently to prevent your
vehicle from closing in on the vehicle ahead.
Note: Vehicle-to-vehicle distance will close in when traveling on long downhill
slopes.

SWITCHING TO CONSTANT SPEED (CRUISE) CONTROL MODE
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.
Refer to the Toyota Owner’s Manual for additional information on DRCC operation,
settings adjustments, limitations, and precautions before attempting to use it.

(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.

AHB is a safety system designed to help drivers see more of what’s ahead at
nighttime while reducing glare for oncoming drivers. When enabled, AHB uses an
in-vehicle camera to help detect the headlights of oncoming vehicles and tail lights
of preceding vehicles, then automatically switches between high and low beams
as appropriate to provide the most light possible and enhance forward visibility.
By using high beams more frequently, the system may allow earlier detection of
pedestrians and obstacles.
Refer to the Toyota Owner’s Manual for additional information on AHB operation,
settings adjustments, limitations, and precautions before attempting to use it.
Automatic High Beams (AHB)
TOYOTA SAFETY SENSE™
(1) With the engine switch in IGNITION ON mode and headlight switch turned to
“AUTO” or “
” position, push lever away from you.
(2) Depress the Automatic High Beam “
” switch.
The AHB indicator will come on when the headlights are turned on automatically
to indicate that the system is active.
Note: Pull the lever back toward you to turn the AHB system off.
The AHB indicator will turn off and the high beam indicator “
” turns on.
When all of these conditions are met, high beams will be automatically turned on
(after approximately 1 second):
• Vehicle speed is above approximately 21 mph (34 km/h).
• The area ahead of the vehicle is dark.
• There are no oncoming or preceding vehicles with headlights or tail lights turned on.
• There are few street lights on the road ahead.
If any of these conditions occur, the system is designed to automatically turn off
high beams:
• Vehicle speed drops below approximately 17 mph (27 km/h).
• The area ahead of the vehicle is not dark.
• Oncoming or preceding vehicles have headlights or tail lights turned on.
• There are many streetlights on the road ahead.

the Automatic Locking Retractor (ALR) will prevent it from being re-extended
beyond that point, unless fully retracted again. This feature is used to help
hold child restraint systems securely.

Tire Pressure Monitoring (warning) System (TPMS)
The tire pressure detected by the tire pressure warning system can be displayed
on the multi-information display (MID).
Refer to the load label on the door jamb or the Owner’s Manual for tire inflation
specifications
If the tire pressure indicator flashes for more than 60 seconds and then remains on,
take the vehicle to your local Toyota dealer.
NOTE: The warning light may come on due to temperature changes or
changes in tire pressure from natural air leakage. If the system has not been
initialized recently, setting the tire pressures to factory specifications should
turn off the light.
Until Complete
The tire pressure warning system can be selected on of the multi-information
display (MID).
System rest initialization

SAFETY & EMERGENCY FEATURES
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 System
TM, 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.
