When Driving
Drive Selection (Automatic Transaxle)∗
●When the sport mode is selected, driving at higher engine speeds increases
and it may increase fuel consumption. Toyota recommends that you cancel
the sport mode on normal driving.
● Drive mode cannot be switched in the following conditions:
• ABS/TCS/DSC is operating
• Steering wheel is being operated abruptly
Press the drive selection switch to
the side (forward) to select
the sport mode.
Pull the drive selection switch to
the side (backward) to cancel
the sport mode.
●When the ignition is switched off, the sport mode is canceled.
● Depending on the driving conditions when sport mode is selected, the vehi-
cle may perform shift-down or slightly accelerate.
∗: If equipped
Drive selection is a system to switch the vehicle’s drive mode.
When the sport mode is selected, vehicle’s response against
accelerator operation is enha nced. This provides additional
quick acceleration which may be needed to safely make maneu-
vers such as lane changes, me rging onto free ways, or passing
other vehicles.
WARNING
Do not use the sport mode when driving on slippery roads such as wet or
snow-covered roads. It may cause tire slipping.

Power Steering
• Power steering is only operable when the engine is running. If theengine is off or if the power steeri ng system is inoperable, you can
still steer, but it requires more physical effort.
If the steering feels stiffer than usual during normal driving or the
steering vibrates, consul t your Toyota dealer.
• The warning light notifies the dr iver of system abnormalities and
operation conditions.
In addition, the buzzer may also activate depending on the system
abnormality or operation condition.
Refer to Warning Lights on P. 157.
Refer to Power Steering Warning Buzzer on P. 516.
NOTICE
Never hold the steering wheel to the extreme left or right for more than 5
seconds with the engine running. This could damage the power steering
system.

●The Smart City Brake Support (SCBS) system will not operate if the driver is
deliberately performing driving operations (accelerator pedal and steering
wheel).
● The Smart City Brake Support (SCBS) system will operate under the follow-
ing conditions.
• The engine is running.
• The Smart City Brake Support (SCB S) warning light (amber) does not
illuminate.
• The vehicle speed is between about 2 to 18 mph (4 to 30 km/h).
• The Smart City Brake Support (SCBS) system is not turned off.
• The DSC is not malfunctioning.
● The Smart City Brake Support (SCBS) detects a vehicle ahead by emitting a
near-infrared laser beam and receiving the beam reflected off the reflector
of the vehicle ahead, and then using it for the measurement. Consequently,
the Smart City Brake Support (SCBS) may not operate under the following
conditions:
• Reflection of the laser is poor due to the shape of the vehicle ahead.
• The vehicle ahead is significantly dirty.
• Under bad weather condition, such as rain, fog and snow.
• The window washer is being used or the windshield wipers are not used
when it’s raining.
• The windshield is dirty.
• The steering wheel is turned completely left or right, or the vehicle is
accelerated rapidly and comes close to the vehicle ahead.
• Trucks with low loading platforms and vehicles with an extremely low or high profile.
• Vehicles with certain shapes such as a vehicle carrier.
● Under the following conditions, the Smart City Brake Support (SCBS) sys-
tem may not operate normally.
• Heavy luggage is loaded in the luggage compartment or on the rear seat.
• If there is the possibility of partial contact with a vehicle ahead.
• When driving on continuously curving roads, and entering and exiting
exits.
• Elongated luggage or cargo is loaded onto installed roof rails and covers the laser sensor.
• Exhaust gas from the vehicle in front, sand, snow, and water vapor rising

3-10. Active Safety System
WARNING
■Do not rely on the Smart City Br ake Support System (SCBS) as a sub-
stitute for safer driving
The Smart City Brake Support (SCB S) system cannot compensate for
unsafe and reckless driving, excessive speed, tailgating (following another
vehicle too closely), and driving on slippery roads such as wet, snowy, and
icy roads (reduced tire friction and road contact because of water on the
road surface). You can still have an accident.
■ Do not rely completely on the Sm art City Brake Support (SCBS) system
● The Smart City Brake Support (SCBS) system is only designed to reduce
damage in the event of a collision. Over reliance on the system leading to
the accelerator pedal or brake pedal being mistakenly operated could
result in an accident.
● The Smart City Brake Support (SCB S) is a system which operates in
response to a vehicle ahead. The system may not be able to detect or
react to two-wheeled vehicles or pedestrians.
● The laser sensor for the Smart City Brake Support (SCBS) system is
installed near the rearview mirror. To assure the correct operation of the
Smart City Brake Support (SCBS), heed the following cautions.
• Do not apply stickers to the surface of the windshield near the laser
sensor (including transparent stickers). Otherwise, the laser sensor
may not be able to detect vehicles ahead which could result in an acci-
dent.
• Do not apply coating agent to the windshield. Otherwise, the laser sen- sor may not be able to detect vehicles or obstructions in front which
could result in an accident.
• Do not disassemble the laser sensor.
• If cracks or damage caused by flying gravel or debris is visible near
the laser sensor, stop using the Smart City Brake Support (SCBS)
system immediately and have your vehicle inspected by your Toyota
dealer. If the vehicle continues to be driven with cracks or scratch
marks left on the windshield near the laser sensor, the system may
operate unnecessarily and cause an unexpected accident.
Refer to Stopping The Smart City Brake Support (SCBS) System
Operation on P. 210.
• When replacing the windshield wipers or windshield, consult your Toyota dealer.
● The laser sensor includes a function for detecting a soiled windshield and
informing the driver, however, depending on the conditions, it may not
detect plastic shopping bags, ice or snow on the windshield. In such
cases, the system cannot accurately determine a vehicle ahead and may
not be able to operate normally. Always drive carefully and pay attention to
the road ahead.

When Driving
If the Smart City Brake Support
(SCBS) is operating, the indicator
light (red) flashes.
WARNING
■Do not modify the suspension
If the vehicle height or inclination is changed, the system will not be able to
correctly detect vehicles ahead. This will result in the Smart City Brake Sup-
port (SCBS) system not operating norma lly or mistakenly operating, which
could cause a serious accident.
■ Turn off the Smart City Brake Support (SCBS) when the vehicle is run-
ning on a chassis roller or being towed
Turn off the Smart City Brake Support (SCBS) system to prevent mistaken
operation when the vehicle is running on a chassis roller or being towed.
Refer to Stopping The Smart City Brake Support (SCBS) System Operation
on P. 210.
NOTICE
● When driving off-road in areas where there is grass or forage, it is recom-
mended that the Smart City Brake Support (SCBS) system be turned off.
● Always use tires for all wheels that are of the specified size, and the same
manufacturer, brand, and tread pattern. In addition, do not use tires with
significantly different wear patterns on the same vehicle as the Smart City
Brake Support (SCBS) system may not operate normally.

3-12. Tire Pressure Monitoring System
Tire Pressure Monitoring System∗
The system monitors the tire pres-
sures indirectly using the data
sent from the ABS wheel speed
sensors.
To allow the system to operate correctly, the system needs to be ini-
tialized with the specified tire pressure (value on the tire pressure
label). Follow the procedure and perform the initialization.
Refer to Tire Pressure Monitoring System Initialization on P. 221.
The warning light flashes when the system has a malfunction.
Refer to Warning Lights on P. 157.
∗: If equipped
The Tire Pressure Monitoring System (TPMS) monitors the air
pressure of all four tires. If the air pressure of one or more tires
is too low, the system warns the driver by indicating the tire
pressure monitoring system warning light in the combination
meter and operating a beep sound.

3-12. Tire Pressure Monitoring System
NOTICE
●Each tire, including the spare (if provided), should be checked monthly
when cold and inflated to the inflation pressure recommended by the
vehicle manufacturer on the vehicle placard or tire inflation pressure
label. (If your vehicle has tires of a different size than the size indicated
on the vehicle placard or tire inflation pressure label, you should deter-
mine the proper tire inflation pressure for those tires.)
As an added safety feature, your vehicle has been equipped with a tire
pressure monitoring system (TPMS) that illuminates a low tire pres-
sure telltale when one or more of your tires is significantly under-
inflated. Accordingly, when the low tire pressure telltale illuminates,
you should stop and check your tires as soon as possible, and inflate
them to the proper pressure. Driving on a significantly under-inflated
tire causes the tire to overheat and can lead to tire failure. Under-infla-
tion also reduces fuel efficiency and tire tread life, and may affect the
vehicle’s handling and stopping ability.
Please note that the TPMS is not a s ubstitute for proper tire mainte-
nance, and it is th e driver’s responsibility to maintain correct tire pres-
sure, even if under-inflation has not reached the level to trigger
illumination of the TPMS lo w tire pressure telltale.
Your vehicle has also been equipped with a TPMS malfunction indica-
tor to indicate when the system is not operating properly.
The TPMS malfunction indicator is combined with the low tire pressure
telltale. When the system detects a malfunction, the telltale will flash
for approximately one minute and then remain continuously illumi-
nated. This sequence will contin ue upon subsequent vehicle start-ups
as long as the malfunction exists . When the malfunction indicator is
illuminated, the system ma y not be able to detect or signal low tire
pressure as intended. TPMS malfunctions may occur for a variety of
reasons, including the installation of replacement or alternate tires or
wheels on the vehicle that prevent the TPMS from functioning properly.
Always check the TPMS malfunction telltale after replacing one or
more tires or wheels on your vehi cle to ensure that the replacement or
alternate tires and wheels allow the TPMS to continue to function prop-
erly.
●To avoid false readings, the system samples for a little while before
indicating a problem. As a result it will not instantaneously register a
rapid tire deflation or blow out.
