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 vehicle-to-vehicle
following distance and operates to maintain a preset following distance \
from the
vehicle ahead. These distances vary based on vehicle speed.
(1)(2)(3)
(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 ahead
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.

Automatic High Beams (AHB)
ACTIVATING THE AHB SYSTEM
CONDITIONS WHERE AHB WILL TURN ON/OFF AUTOMATICALLY
When all of these conditions are met, high beams will be automatically t\
urned 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 ligh\
ts turned on.
• There are few streetlights on the road ahead.
If any of these conditions occur, high beams will be automatically turne\
d off:

d on.
• There are many streetlights on the road ahead.
AHB is a safety system designed to help drivers see more of what’s ah\
ead at
nighttime while reducing glare for oncoming drivers, AHB uses an in-vehi\
cle
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\

Emergency tire puncture repair kit
SAFETY & EMERGENCY FEATURES
Your vehicle is not equipped with a spare tire, but instead is equipped with an
emergency tire puncture repair kit (bottle of sealant and compressor.)
After temporarily repairing the tire with the repair kit, have the tire \
repaired or
replaced by your Toyota dealer.
Refer to the Owner’s Manual for more details.
LOCATION
Tire Pressure Monitoring (warning) System (TPMS)
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 is designed to turn on when tire pressure is critically lo\
w, but it may
also 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

Star Safety System™
SAFETY & EMERGENCY FEATURES
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.
Enhanced Vehicle Stability Control provides cooperative control of the A\
BS, TRAC,
VSC and EPS.
Enhanced VSC helps to maintain directional stability when loss of tracti\
on occurs
during a turn.
ENHANCED VEHICLE STABILITY CONTROL (VSC)
Toyota’s ABS sensors detect which wheels are locking up and limits wh\
eel lockup
by “pulsing” each wheel’s brakes independently. Pulsing release\
s brake pressure
repeatedly for fractions of a second. This helps the tires attain the tr\
action that
current road conditions will allow, helping you to stay in directional c\
ontrol.
ANTI-LOCK BRAKE SYSTEM (ABS)
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 f\
our wheels.
ELECTRONIC BRAKE FORCE DISTRIBUTION (EBD)
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 qui\
ckly than
just the driver alone can.
BRAKE ASSIST (BA)
SMART STOP TECHNOLOGY (SST)
Smart Stop Technology automatically reduces motor power when the acceler\
ator
and brake pedals are pressed simultaneously under certain conditions.
SST engages when the accelerator is depressed first and the brakes are a\
pplied
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 acceler\
ator pedal,
allowing vehicles to start on a steep hill and safely accelerate without\
rolling
backward.

Floor mat installation
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 theΔmarks
Brake Assist (BA)
VSC helps prevent loss of traction during cornering by reducing Motor po\
wer
output, 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 star\
ts to slip.
TRAC limits Motor power output and applies the brakes to the spinning wh\
eel. This
transfers power to the wheels that still have traction to help keep you \
on track.
