SAFETY & EMERGENCY FEATURES
SWITCHING TO CONSTANT SPEED (CRUISE) CONTROL MODE
If you are already using DRCC, push “” button to turn the system off first, then
push and hold the button for at least 1.5 seconds to switch.
Note: When the vehicle is turned off, it will automatically default to DRCC.
To adjust speed or cancel, see steps (2) and (3) of ADJUSTING SET SPEED on
page 56.
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.
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.
Automatic High Beams (AHB)
When all of the following conditions are met, the high beams will be aut\
omatically
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 the following conditions occur, the high beams will be automat\
ically turned off: • 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 turne\
d on.
• There are many streetlights on the road ahead.
ACTIVATING THE AHB SYSTEM
CONDITIONS WHERE AHB WILL TURN ON/OFF AUTOMATICALLY
The Automatic High Beams (AHB) safety system is designed to help you s\
ee
more clearly at night. At speeds above 25 mph, AHB can detect the headli\
ghts of
oncoming vehicles and taillights of preceding vehicles, then automatical\
ly toggles
between high and low beams accordingly.
See www.toyota.com/safety-sense for more information.
Refer to the Toyota Owner’s Manual for a list of additional situation\
s in which the
system operation may be limited.
(2) (1)
(1) Press the “
” switch.
(2) Turn the headlight switch to the “AUTO” or “
” position.
The AHB indicator will come on when the headlights are turned on automat\
ically
to indicate that the system is active.
Note: Push the lever away from you to manually turn on high beams. Press the
AHB switch to turn the AHB system off.
The AHB indicator will turn off and “
” or “” will turn on. To activate the
system again, pull the lever its original position or press the “
” switch.

SAFETY & EMERGENCY FEATURES
VEHICLE STABILITY CONTROL (VSC)
VSC helps prevent loss of traction during cornering by reducing engine power and
applying brake force to selected wheels.
Toyota’s VSC monitors steering angle and the direction your vehicle is traveling.
When it senses that the front or rear wheels begin to lose traction, VSC reduces
engine power and applies braking to selected wheels. This helps restore traction
and vehicle control.
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.
SMART STOP TECHNOLOGY (SST)
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.

SAFETY & EMERGENCY FEATURESFloor mat installation
TRACTION CONTROL (TRAC)
VSC helps prevent loss of traction during cornering by reducing engine p\
ower, and
Traction Control helps maintain traction on loose gravel and wet, icy, o\
r uneven
surfaces by applying brake force to the spinning wheel(s).
Toyota’s TRAC sensors are activated when one of the drive wheels star\
ts to slip.
TRAC limits engine 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.
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.
Always align the Δ marks
