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.

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.

Floor mat installation
Trailer Sway Control
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 marks
Trailer sway may occur when towing a trailer due to strong crosswinds, uneven and/
or winding road conditions or the driver’s steering input.
Trailer Sway Control uses sensors to detect trailer sway and then simultaneously
and automatically helps to suppress the swaying motion of the trailer by integrating
brake and engine torque control to reduce speed and to help quickly control the
swaying motion of the trailer.
TRACTION CONTROL (TRAC)
VSC helps prevent loss of traction during cornering by reducing engine power, 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 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.
