ADJUSTING SET SPEED
Intended for highway use, Dynamic Radar Cruise Control (DRCC) lets you\
drive at
a preset speed. DRCC is designed to function at speeds of 25-110 mph and\
uses
vehicle-to-vehicle distance control, helping maintain a preset distance \
from the
vehicle ahead of you.*
* Not available on all models. See toyota.com/safety-sense for model app\
licability.
Refer to the Toyota Owner’s Manual for a list of additional situation\
s in which the
system operation may be limited.
Vehicle will cruise at a set speed, decelerate to maintain selected dist\
ance 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” and “
” 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 v\
ehicle
up to approximately 328 ft (100 m) ahead, determines the current vehic\
le-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 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 brake 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 downhill
slopes.

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 swit\

TOYOTA SAFETY SENSE™
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 toyota.com/safety-sense for more information.

• 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\

If the tire pressure indicator flashes for 1 minute 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.
NOTE: If a passenger’s seat belt is fully extended, then retracted even slightly,
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.
