FEATURES & OPERATIONS
Push and turnTurn
Shifting between “2WD” and “4H”
Reduce speed to less than 62 mph, then turn control to “2WD” or “4H.”
Shifting between “4H” and “4L”
When stopped shift to “N” position, then push and turn to “4L” from “4H.”
NOTE: For best fuel economy and performance under normal driving
conditions, keep in “2WD” position.
2WDHigh speed (2WD) Normal driving on dry hard-surfaced roads.
4HHigh speed (4WD) For driving only on roads that permit the tires to
slide, like off-road, icy or snow-covered roads.
4L
Low speed (4WD)
For maximum power and traction when climbing or descending steep
hills, off-road driving, and hard pulling in sand, mud or deep snow.

Two & four-wheel drive selector (if equipped)
The trailer brakes can be controlled by the Trailer brake controller via the 7-pin
connector. By selecting the type of brakes that are being used on the trailer
(electric or electric-over-hydraulic) and setting the gain for the controller, the
manual TRAILER BRAKE OUTPUT slider is used to slow just the trailer. The vehicle
brake pedal will also slow down as well as stop the trailer when applied. Gain
values, manual brake outputs, trailer brake types and the trailer connection status
are displayed in the multi-information display.
Refer to the Owner’s Manual for more details.

SAFETY & EMERGENCY FEATURES
Star Safety System™
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 SystemTM, 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.
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.

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.
