G-force display
●Depending on the vehicle usage conditions, the brake fluid pressure dis-
play may not reach its maximum reading even though the brake pedal is
fully depressed.
● If a battery terminal is disconnected and reconnected, the steering
amount display may be disabled temporarily. After driving the vehicle for
a while, the display will be enabled.
■ Suspension of the settings display
●The settings cannot be changed while driving. When changing settings,
park the vehicle in a safe place.
● If a warning message is displayed, operation of the settings display will
be suspended.
■ Using the stopwatch
If the engine is stopped while the stopwatch is operating, the stopwatch will
stop and the time up to that point will be recorded.
■ Outside temperature display
●In the following situations, the correct outside temperature may not be
displayed.
• When the vehicle is very hot, such as when under the sun.
• When the vehicle is idling or being driven at low speeds such as in a
traffic jam or when the engine is stopped and then restarted immedi-
ately afterward.
• When the actual outside temperature is outside of the indicator range.
● If “ − − ” is displayed for approximately 1 minute or more or if the outside
temperature is not displayed, the system may be malfunctioning.Have
the vehicle inspected by any authorized Toyota dealer or repairer, or
another duly qualified and equipped professional.

Daytime running light system
●Vehicles with an automatic transmission: To make your vehicle more visi-
ble to other drivers during daytime dr iving, the daytime running lights turn
on automatically whenever the engine is started and the parking brake is
released with the headlight switch off or in the “AUTO” position. (Illumi-
nate brighter than the front position lights.) Daytime running lights are not
designed for use at night.
● Vehicles with a manual transmission: To make your vehicle more visible
to other drivers during daytime drivi ng, the daytime running lights turn on
automatically whenever the engine is started and the parking brake is
released with the headlight switch off or in the “AUTO” position. (Illumi-
nate brighter than the front position lights.) Daytime running lights are not
designed for use at night.
■ Headlight control sensor (if equipped)
Headlight control sensor is located on the
passenger's side.
The sensor may not function properly if
an object is placed on the sensor, or any-
thing that blocks the sensor is affixed to
the windshield.
Doing so interferes with the sensor
detecting the level of ambient light and
may cause the automatic headlight sys-
tem to malfunction.

Cruise control can be set when
Vehicles with an automatic transmission
●The shift lever is in D or M and the vehicle is in the 2
nd gear or higher.
● Vehicle speed is above approximately 40 km/h (25 mph).
Vehicles with a manual transmission
● The vehicle is in the 2
nd gear or higher.
● Vehicle speed is above approximately 40 km/h (25 mph).
■ Canceling and resuming the constant speed control
Pulling the lever toward you
cancels the constant speed
control.
The speed setting is also can-
celed when the brakes are
applied or the clutch pedal
(manual transmission only) is
depressed.
Pushing the lever up
resumes the constant
speed control.
Resuming is available when
the vehicle speed is more than
approximately 32 km/h (20
mph).

Driving assist systems
To help enhance driving safety and performance, the following sys-
tems operate automatically in response to various driving situations.
Be aware, however, that these systems are supplementary and
should not be relied upon too heavily when operating the vehicle.
■ ABS (Anti-lock Brake System)
Helps to prevent wheel lock when the brakes are applied suddenly, or if
the brakes are applied while driving 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 Stability 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 pr event 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 suddenly, the emergency flashers auto-
matically flash quickly to alert the vehicle behind.

When the TRC/VSC systems are operating
The slip indicator light will flash
while the TRC (brake LSD func-
tion)/VSC systems are operat-
ing.
Disabling the TRC systemIf the vehicle gets stuck in mud, dirt or snow, the TRC system may
reduce power from the engine to the wheels. Pressing 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 the
button.
The “TRC OFF” indicator light will
come on.
Press the button again to turn the
system back on.

“TRACK” mode
Your vehicle is equipped with two types of control modes to accom-
modate various driving preferences. The control modes can be
selected with the “TRACK” switch. Normal mode allows secure and
smooth normal driving. When the switch is pressed and held for 1
second or more, “TRACK” mode is activated. Control characteristics
such as the VSC and TRC are adjusted to afford maneuverability
closer to what a driver may desire, while a sense of security is
retained. “TRACK” mode/Normal mode
The “TRACK” indicator and VSC
off indicator come on when in
“TRACK” mode.
To change back to normal mode
while in “TRACK” mode, press
or the “TRACK” switch.
Turning off both TRC and VSC systemsTo turn the TRC and VSC systems off, press and hold for more
than 3 seconds while the vehicle is stopped.
The “TRC OFF” indicator light and the VSC off indicator light will
come on.
However, on vehicles with an automatic transmission, the brake LSD
function will remain on.
Press the button again to turn the systems back on.

■ Sounds and vibrations caused by the ABS, brake assist, TRC and VSC
systems
●A sound may be heard from the engine compartment when the brake
pedal is depressed repeatedly, when the engine is started or just after the
vehicle begins to move. This sound does not indicate that a malfunction
has occurred in any of these systems.
● Any of the following conditions may occur when the above systems are
operating. None of these indicates that a malfunction has occurred.
• Vibrations may be felt through the vehicle body and steering.
• A motor sound may be heard after the vehicle comes to a stop.
• The brake pedal may pulsate slightly after the ABS is activated.
• The brake pedal may move down slightly after the ABS is activated.
■ EPS operation sound
When the steering wheel is operated, a motor sound (whirring sound) may
be heard. This does not indicate a malfunction.

Automatic reactivation of TRC and VSC systems
After turning the TRC and VSC systems off, the systems will be automati-
cally reactivated in the following situations:
●Vehicles without a smart entry & start system: When the engine switch is
turned to “LOCK” position
● Vehicles with a smart entry & start system: When the “ENGINE START
STOP” switch is turned off
● If only the TRC system is turned off, the TRC will turn on when vehicle
speed is more than approximately 50 km/h (31 mph).
If both the TRC and VSC systems are turned off, automatic reactivation
will not occur when vehicle speed increases.
■ Reduced effectiveness of the EPS system
The effectiveness of the EPS system is reduced to prevent the system from
overheating when there is frequent steer ing input over an extended period of
time. The steering wheel may feel heavy as a result. Should this occur,
refrain from excessive steering input or stop the vehicle and turn the engine
off. The EPS system should return to normal after a little while.
■ Automatic deactivation of “TRACK” mode
Vehicles without a smart entry & start system
When the engine switch is turned to “LOCK” position after driving in
“TRACK” mode, the mode is automatically deactivated.
Vehicles with a smart entry & start system
When the “ENGINE START STOP” switch is turned off after driving in
“TRACK” mode, the mode is automatically deactivated.
■ Operating conditions of emergency brake signal
When the following three conditions are met, the emergency brake signal
will operate:
●The emergency flashers are off.
● Actual vehicle speed is over 60 km/h (38 mph).
● The brake pedal is depressed in a manner that cause the system to
judge from the vehicle deceleration that this is a sudden braking opera-
tion.
