FEATURES & OPERATIONS
Shift the shift lever to “S” position from “D” position.
Floor shift type:
+ : Upshift (push and release)
- : Downshift (pull and release)
Column shift type:
+ : Upshift (push and release)
- : Downshift (push and release)
Downshifting increases power going uphill, or provides engine braking downhill. For
best fuel economy during normal driving conditions, always drive with the shift lever
in the “D” position.
* The engine switch must be in the “ON” position (without Smart Key)/“IGNITION
ON” mode (with Smart Key) and the brake pedal depressed to shift from Park.

TOW/HAUL switch (if equipped)
“Tow/Haul” mode is ideal for use when carrying heavy loads. When the TOW/HAUL
switch is pressed, throttle response and transmission control are optimized for the
high performance operation. As fuel economy is reduced while in “Tow/Haul” mode,
deactivating when driving without a load is recommended.
• Upshifts occur at higher engine speeds to expand the use of lower gear
ranges, enhancing power performance during towing and preventing
repeated gear changes.
• Downshifts occur at a greater accelerator pedal angle to allow the
vehicle to stay in a higher gear, reducing repeated gear changes.
• Downshifts occur at a lower accelerator pedal angle to allow the
vehicle to stay in a lower gear, enhancing towing ability.
• When the accelerator pedal is wide open, upshift timing is optimized to
effectively use the maximum engine power range available.
When Tow/Haul is engaged, the opening angle of the electronically
controlled throttle is wider for any given accelerator pedal position than
normal, enhancing acceleration feeling and response.
• During uphill driving, the gear position is held to prevent repeated upshifting.
• During downhill driving, downshifting to lower gears will occur to effectively use
engine braking.
Refer to the Owner‘s Manual for more details on this system before attempting to
use it.

SWITCHING TO CONSTANT SPEED (CRUISE) CONTROL MODE
SETTING CONSTANT SPEED (CRUISE) CONTROL
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 button again to turn the system off
first, then push and hold button for at least 1.5 seconds to switch.
Note: When the engine is turned off, it will automatically default to DRCC.
(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.

Refer to the Toyota Owner’s Manual for additional information on DRCC operation,
settings adjustments, limitations, and precautions before attempting to use it.

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)
(1) With the engine switch in IGNITION ON mode, turn the headlight switch to
“” or “AUTO” position.
(2) Push lever away from you.
(3) Press the “” 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. To turn switch to “” position and the manual
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.

System reset initialization
1. Push and hold “ SET” button until the indicator blinks three times.
2. Wait several minutes to allow initialization to complete.
After adjusting tire pressures, or after tires have been rotated or replaced, turn the
ignition switch to “ON” and press and hold the “SET” button until indicator blinks
three times. Let the vehicle sit for a few minutes to allow initialization to complete.
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.
Push up, or squeeze lock release to lowerPush up, or squeeze lock release to lower
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.
To find more information about seat belts, and how to install a child restraint
system, refer to the Owner’s Manual.
