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 v\
ehicle
up to approximately 328 ft (100m) ahead, determines the current vehicl\
e-to-vehicle
following distance and operates to maintain a suitable following distanc\
e 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 dis\
tance
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 automaticall\
y
decelerates your vehicle. When a greater reduction in vehicle speed is
necessary, the system applies the brakes (the stop lights will come on \
at this
time). The system will respond to changes in the speed of the vehicle a\
head
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 d\
ownhill
slopes.

SWITCHING TO CONSTANT SPEED CONTROL MODE
Note: When your vehicle is too close to a vehicle ahead, and sufcien\
t
automatic deceleration via the cruise control is not possible, the displ\
ay will
ash and the buzzer will sound to alert the driver. An example of thi\
s 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 DR\
CC.
Refer to a Toyota Owner’s Manual for additional information on DRCC o\
peration,
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.

SAFETY & EMERGENCY FEATURESStar Safety System
™
There are two types of Toyota floor mats: carpeted and all-weather. Each vehicle
has model-specific floor mats. Installation is easy.
To keep your floor mat properly positioned, follow these steps:
• Only use Toyota floor mats designed for your specific model.
• Use only one floor mat at a time, using the retaining hooks to keep the mat in place.
• Install floor mats right side up.
ENHANCED VEHICLE STABILITY CONTROL (VSC)
SMART STOP TECHNOLOGY (SST)
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.
TRACTION CONTROL (TRAC)
VSC helps prevent loss of traction during cornering by reducing Hybrid System
output, and Traction Control helps maintain traction on loose gravel and wet, icy, or
uneven surfaces by applying brake force to the spinning wheel(s).
Toyota’s TRAC sensors are activated when one of the drive wheels starts to slip.
TRAC limits Hybrid System output and applies the brakes to the spinning wheel.
This transfers power to the wheels that still have traction to help keep you on track.
ELECTRONIC BRAKE FORCE DISTRIBUTION (EBD)
Toyota’s ABS technology has Electronic Brake-force Distribution (EBD) to help
maintain control and balance when braking. Abrupt stops can cause a vehicle to tilt
forward, reducing the braking power of the rear wheels. EBD responds to sudden
stops by redistributing brake force to enhance the braking effectiveness of all four
wheels. All new Toyota vehicles come standard with the Star Safety System
TM, which
combines Vehicle Stability Control (VSC), Traction Control (TRAC), Anti-lock Braking
System (ABS), Electronic Brake-force Distribution (EBD), Brake Assist (BA) and Smart
Stop Technology (SST).
Refer to the Owner’s Manual for more details and important information on limitations
to these systems.
Smart Stop Technology automatically reduces driving torque when the accelerator
and brake pedals are pressed simultaneously under certain conditions.
