When the P position control system malfunctions
The “POWER” switch will not be able to be turned off. In such a case, the
switch can be turned off after applying the parking brake.
Have the vehicle inspected by any authorized Toyota dealer or repairer, or
another duly qualified and equipped professional immediately.
Meter display
When the “POWER” switch is turned off, each display will extinguish as fol-
lows.
The shift position indicator will extinguish after approximately 2 seconds.
The odometer, clock, etc. will extinguish after approximately 30 seconds.
(Each display will also extinguish immediately if a door is locked before 30
seconds has elapsed)
CAUTION
When starting the hybrid system
Always start the hybrid system while sitting in the driver’s seat. Do not
depress the accelerator pedal while starting the hybrid system under any cir-
cumstances.
Doing so may cause an accident resulting in death or serious injury.
Stopping the hybrid system in an emergency
If you want to stop the hybrid system in an emergency while driving the vehi-
cle, press and hold the “POWER” switch for more than 3 seconds, or press it
briefly 3 times or more in succession.
However, do not touch the “POWER” switch while driving except in an emer-
gency. Turning the hybrid system off while driving will not cause loss of
steering or braking control, but the power assist to these systems will be lost.
This will make it more difficult to steer and brake, so you should pull over
and stop the vehicle as soon as it is safe to do so.

Touch tracer display
When the audio control switches,
climate control switches, “DISP”
button or “TRIP” button of the
steering wheel are touched, the
touch tracer display will appear
in front of the display, with the
touched button highlighted to
allow the driver to identify the
button that is being operated.
The button can then be operated
by further presses.
If an audio/navigation system is
used that is not compatible with
the steering switches in this vehi-
cle, the audio switch display may
not operate correctly.

Customizing the display
The following display can be shown or hidden.
Turn-by-turn navigation display (if equipped)
Touch tracer display
Temperature display which is set by the steering switches.
Press and hold the “SET” switch.
Customization can be performed
when the head-up display is on
and the vehicle is traveling at less
than 8 km/h (5 mph).
Press the “SET” switch and

CAUTION
When the sensor may not be correctly detecting the vehicle ahead
Apply the brakes as necessary when any of the following types of vehicles
are in front of you.
As the sensor may not be able to correctly detect these types of vehicles,
the approach warning (P. 287) will not be activated, and a fatal or serious
accident may result.
Vehicles that cut in suddenly
Vehicles traveling at low speeds
Vehicles that are not moving
Vehicles with small rear ends (trailers with no load on board etc.)
Motorcycles traveling in the same lane
Conditions under which the vehicle-to-vehicle distance control may
not function correctly
Apply the brakes as necessary in the following conditions as the radar sen-
sor may not be able to correctly detect vehicles ahead, and a fatal or serious
accident may result:
When water or snow thrown up by the surrounding vehicles hinders the
functioning of the sensor
When your vehicle is pointing upwards (caused by a heavy load in the lug-
gage compartment etc.)
When the road curves or when the lanes are narrow
When steering wheel operation or your position in the lane is unstable
When the vehicle ahead of you decelerates suddenly

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 prevent the drive wheels from spin-
ning when starting the vehicle or accelerating on slippery roads
EPS (Electric Power Steering)
Employs an electric motor to reduce the amount of effort needed to turn
the steering wheel

VSC+ (Vehicle Stability Control+)
Provides cooperative control of the ABS, TRC, VSC and EPS.
Helps to maintain directional stability when swerving on slippery road
surfaces by controlling steering performance.
Hill-start assist control
P. 304
PCS (Pre-Crash Safety System) (if equipped)
P. 307
Emergency brake signal (if equipped)
When the brakes are applied suddenly, the stop lights automati-
cally flash to alert the vehicle behind.
