●Steep downhill grades
• The set vehicle speed may be
exceeded.
●On a steep continuous downhill
grade
• The brakes may overheat.
●Roads and overpasses with
repeated steep uphill and downhill grades
• Detection of the vehicle in front may
be lost, or the road surface may be detected instead of the vehicle in
front, making correct control impos-
sible.
●Entering a sharp curve/turn into an
interchange or junction, or a service area, parking area, toll booth or
other facilities
• Detection of the vehicle in front may not be possible.
●There are changes in brightness, such as at a tunnel entrance or exit.
●Visibility is poor due to sand, smoke or water vapor blowing in the wind,
or the front vision is obscured due
to water splashes, snow, dirt, water spray from road sprinklers or snow
clearing sprinklers on the road, or
dust stir up generated by the vehi- cle in front or oncoming traffic.
• Detection of the vehicle in front may
be lost, or water or other sub- stances may be incorrectly
detected instead, making correct
control impossible.
●In adverse weather, such as heavy snow or snowstorms

• On curved roads, at the start and
end of a curve and on roads with
continuous curves (These condi- tions make it difficult for the system
to detect vehicles because they are
outside the detectable area.)
• On an on-ramp or off-ramp to a
freeway, highway, or other
restricted access road (EyeSight Adaptive Cruise Control is not
designed for use in this kind of driv-
ing environment.)
• In an urban or suburban environ-
ment (Adaptive Cruise Control is not appropriate for use in these
driving areas. Use Adaptive Cruise
Control only on limited-access high- ways.)
• The vehicle in front is not directly ahead of your vehicle and is shifted
to one side.
• There is an obstacle on the side of the road.
• The relative speed difference com- pared to the vehicle in front is large.
• A vehicle cuts into your lane in front of you.
• The distance between vehicles is extremely short.
• Your vehicle is drifting within the lane.
• On a bumpy or unpaved road sur- face.
• On a road with extremely narrow lanes, such as when traffic restric-
tions are in effect or in areas where
construction work is taking place.
• Normal driving has become unsta-
ble due to an accident or malfunc- tion.
• Extremely heavy cargo is loaded in the rear seat or trunk of your vehi-
cle.
●There are limits to the situation
judgment capabilities of the Adap-
tive Cruise Control system. Decel- eration may not take place in time
in the following situations. Apply the
brake pedal to decelerate the vehi- cle if necessary.
• The speed difference with the vehi-
cle in front is too large or the vehicle in front decelerates unexpectedly.
• The decelerating vehicle in front unexpectedly slows down or sud-
denly brakes.

●If the alert/notification sounds fre-
quently, do not use Adaptive Cruise
Control.
●Even when the following distance is
short, the “Obstacle Detected” warning may not activate in the fol-
lowing situations.
• The difference in speed with the
vehicle in front is small. The two vehicles are traveling at almost the
same speed.
• The vehicle in front is traveling
faster than your vehicle. The follow-
ing distance is gradually increasing.
• Another vehicle cuts into your lane
very close to your vehicle.
• The vehicle in front decelerates
suddenly.
• There are repeated uphill and
downhill grades.
*: The recognition status of the lead
vehicle using the stereo camera
can be confirmed by the illumina-
tion status of the lead vehicle indi-
cator. (P.191)
NOTICE
●After Adaptive Cruise Control has
started, it maintains control continu-
ously according to the behavior of the vehicle in front. When your vehi-
cle comes to a stop because the
vehicle in front has stopped, the automatic braking function will be
canceled immediately after stop-
ping and the vehicle will start creep-
ing forward gradually (at the same time 3 intermittent beeps, 1 short
beep and 1 long beep will sound).
Be sure to depress the brake pedal and stop the vehicle completely.
Note that the vehicle is not main-
tained at a standstill position and will not automatica lly start moving
from a standstill position.
●Braking may not be sufficient
depending on the following condi-
tions. Depress the brake pedal and decelerate as necessary.
• Vehicle conditions (amount of load,
number of occupants, etc.)
• Road conditions (grade, slipperi-
ness, shape, bumps, etc.)
• Vehicle maintenance condition
(brake systems, tire wear, air pres- sure, etc.)
• The brakes are cold. (For example, just after the engine is started or the
outside temperature is low.)
• For a short period of time when
driving after the engine is started
until the engine has warmed-up
• The brakes are overheated on
downhill grades (braking perfor- mance may be reduced).
• In rain or after washing the vehicle (the brakes may become wet and
braking performance may be
reduced.)

accelerating to the set vehicle speed,
vehicle following will be started again.
●When the brakes are applied by
Adaptive Cruise Cont rol, the vehicle’s
stop lights will illuminate.
●Even if there is no lead vehicle pres-
ent, on a downhill grade, the Adaptive Cruise Control’s automatic brake may
operate in order to maintain the set
vehicle speed.
●Some noises may be audible during
automatic braking. This is caused by the braking control and does not indi-
cate a malfunction.
●To temporarily accelerate quickly, use
the accelerator pedal. After accelerat-
ing, the vehicle will gradually return to the set vehicle speed shown in the set
vehicle speed display.
●If the vehicle in front is no longer
detected while your vehicle is still con-
trolled by the automatic braking oper- ation, the brake will be automatically
released gradually. Depress the
accelerator pedal if necessary.
●The lead-vehicle following function
has the following characteristics:
• If the lead vehicle’s stop lights are detected, deceleration will start earlier
than without detection.
• If the vehicle moves to the fast lane while traveling more than approxi-
mately 60 km/h (37 mph), the system
starts acceleration to the set vehicle speed more quickly because it is
linked with the turn signal.
• If the setting of driving lane is different
from the actual driving direction, the
vehicle may start to accelerate faster than usual when the driver signals a
lane change to move from the passing
lane to the driving lane. ( P.377)
●Cruise control acceleration character-
istics can be set to one of four levels. ( P.377)
■Increasing the set vehicle
speed
Using the cruise control switch
 Push to the “+ RES” side briefly.
Every time the switch is pushed, the set
vehicle speed will increase in incre-
ments of 1 km/h (1 mph) increment.
 Push to the “+ RES” side contin-
uously.
While the switch is being pushed, the
set vehicle speed will increase in incre-
ments of 5 km/h (5 mph).
When operating the switch, the set
vehicle speed changes on the
meter display.
NOTICE
If the driver operates the brake pedal
during automatic braking, the pedal
may feel stiff; however, this is not a malfunction. By depressing the brake
pedal further you can apply more
braking force. When the brake pedal is released it will return to its original
condition.

●When Conventional Cruise Control
is functioning, the system does not
perform the following control to maintain a following distance, as
when using Adaptive Cruise Con-
trol. Strive for safe driving and depress
the brake pedal to decelerate the
vehicle as necessary in order to
ensure a safe following distance from the vehicle in front.
●Under the following conditions, do not use Conventional Cruise Con-
trol. Doing so may result in an acci-
dent.
• Roads with heavy traffic or roads
with sharp curves
 Maintaining an appropriate speed
for such road conditions may be diffi-
cult.
• Frozen roads, snow-covered roads
or slippery road surfaces
 The tires may spin, causing your
vehicle to lose control.
• Steep downhill grades
 The set vehicle speed may be
exceeded.
• On a steep continuous downhill grade
 The brakes may overheat.
●When using Conventional Cruise
Control, always set the speed
according to the speed limit, traffic flow, road conditions, and other
conditions.
NOTICE
When using Cruise Control, be sure to check the meter display to confirm
which Cruise Control mode is
selected: Adaptive Cruise Control or Conventional Cruise Control.
●If Adaptive Cruise Control is
selected, illuminates.
●If Conventional Cruise Control is
selected, illuminates.

Reverse Automatic Brak-
ing (RAB) system*
Reverse Automatic Braking
(RAB) is a system designed to
help avoid collisions or reduce
collision damage when revers-
ing the vehicle. If a wall or an
obstacle is detected in the
reversing direction, the system
will notify the driver with a
warning sound and may acti-
vate the vehicle’s brakes auto-
matically.

2564-6. Using other driving systems
■ABS (Anti-lock Brake System)
Helps to prevent wheel lock when
the brakes are applied suddenly, or
if the brakes are applied while driv-
ing on a slippery road surface
■Brake assist
Generates an increased level of
braking force after the brake pedal
is depressed when the system
detects a panic stop situation
■VSC (Vehicle St ability Control)
Helps the driver to control skidding
when swerving suddenly or turning
on slippery road surfaces
■TRC (Traction Control)
Helps to maintain drive power and
prevent the drive wheels from spin-
ning when starting the vehicle or
accelerating on slippery roads
The TRC system is also equipped
with the brake LSD function.
■Hill-start assist control
 P.253
■EPS (Electric Power Steering)
Employs an electric motor to
reduce the amount of effort needed
to turn the steering wheel
■Emergency brake signal
When the brakes are applied sud-
denly, the emergency flashers auto-
matically flash to alert the vehicle
behind.
■When the TRC/VSC systems are
operating
The slip indicator will flash while the TRC (Including brake LSD func-
tion)/VSC systems are operating.
■Disabling the TRC system
If the vehicle gets stuck in mud, dirt or
snow, the TRC system may reduce
power from the engine to the wheels.
Pressing switch to turn the system
off may make it easier for you to rock the
vehicle in order to free it.
In this case, the brake LSD function
remains on.
To turn the TRC system off, quickly
press and release switch.
The TRC OFF indicator will come on.
Press switch again to turn the sys-
tem back on.
Driving assist systems
To help enhance driving safety
and performance, the following
systems operate automatically
in response to various driving
situations. Be aware, however,
that these systems are supple-
mentary and should not be
relied upon too heavily when
operating the vehicle.

4-7. Driving tips
DrivingPerform the following according to
the driving conditions:
 Do not try to forcibly open a win-
dow or move a wiper that is fro-
zen. Pour warm water over the
frozen area to melt the ice. Wipe
away the water immediately to
prevent it from freezing.
 To ensure proper operation of
the climate control system fan,
remove any snow that has accu-
mulated on the air inlet vents in
front of the windshield.
 Check for and remove any
excess ice or snow that may
have accumulated on the exte-
rior lights, vehicle’s roof, chassis,
around the tires or on the brakes.
 Remove any snow or mud from
the bottom of your shoes before
getting in the vehicle.
 If a door is opened and closed
when its side window is frozen,
the window safety device will
operate and the side window
open/close function linked to
door operation may not operate
correctly. If this occurs, perform
the following after the ice has
melted.
After opening the window to the
approximately half open position,
perform initialization. ( P.126)
Accelerate the vehicle slowly, keep
a safe distance between you and
the vehicle ahead, and drive at a
reduced speed suitable to road
conditions.
 Park the vehicle and shift the
shift lever to P (automatic trans-
mission), or 1 or R (manual
transmission) with out setting the
parking brake. The parking brake
may freeze up, preventing it from
being released. If the vehicle is
parked without setting the park-
ing brake, make sure to block the
wheels.
Failure to do so may be danger-
ous because it may cause the
vehicle to move unexpectedly,
possibly leading to an accident.
 Vehicles with an automatic trans-
WA R N I N G
Always use the utmost care when
driving with tire chains - overconfi-
dence because you are driving with tire chains could easily lead to a seri-
ous accident.
NOTICE
■Repairing or replacing snow tires
Request repairs or replacement of snow tires from Toyota dealers or
legitimate tire retailers.
This is because the removal and attachment of snow tires affects the
operation of the tire pressure warning
valves and transmitters.
