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.
Preceding vehicle mark
(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.
1.5 seconds
(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 ah\
ead at
nighttime without dazzling other drivers. When enabled, AHB uses an in-v\
ehicle
camera to help detect the headlights of oncoming vehicles and tail light\
s of
preceding vehicles, then automatically switches between high and low bea\
ms
as appropriate to provide the most light possible and enhance forward vi\
sibility.
By using high beams more frequently, the system may allow earlier detect\
ion of
pedestrians and obstacles.
Refer to a Toyota Owner’s Manual for additional information on AHB op\
eration,
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 tu\
rned 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 automat\
ically
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 t\
urned on
(after approximately 1 second): • Vehicle speed is above approximately 25 mph (40 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 automaticall\
y 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 lightsturned on.
• There are many streetlights on the road ahead.
ACTIVATING THE AHB SYSTEM
CONDITIONS WHERE AHB WILL TURN ON/OFF AUTOMATICALLY
If the Tire Pressure Warning indicator “” illuminates without blinking, adjust tire
pressures to factory-specified levels.* The light will turn off after a \
few minutes. The
warning light may come on due to temperature changes or changes in tire \
pressure
from natural air leakage.
If the tire pressure indicator flashes for more than 60 seconds and then remains on,
take the vehicle to your local Toyota dealer.
Refer to the Owner’s Manual for more details.
* Refer to load label on door jamb or the Owner’s Manual for tire inf\
lation
specifications.
SAFETY & EMERGENCY FEATURES
NOTE: If a passenger’s seat belt is fully extended, then retracted ev\
en slightly,
the Automatic Locking Retractor (ALR) will prevent it from being re-ex\
tended
beyond that point, unless fully retracted again. This feature is used to\
help
hold child restraint systems securely.
To find more information about seat belts, and how to install a child re\
straint system,
refer to the Owner’s Manual.
