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.

When Driving
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.

3-10. Active Safety 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
from manholes and grating, and water splashed into the air.
• When towing a malfunctioning vehicle.
• When driving with tires having significantly different wear.

When Driving
●In the following cases, the laser sensor may inadvertently determine that
there is a vehicle ahead and the Smar t City Brake Support (SCBS) system
may operate.
• Objects on the road at the entrance to a curve.
• Vehicles passing in the opposite lane while making a curve.
• Metal objects, bumps, or protruding objects on the road.
• When passing through a toll gate equipped with a bar.
• When passing under a vinyl curtain or flag.
• Plastic objects such as pylons.
• Two-wheeled vehicles, pedestrians, animals or standing trees.
● Manual transaxle:
If the vehicle is stopped by the SCBS operation and the clutch pedal is not
depressed, the engine stops.
● The Smart City Brake Support (SCBS) warning light (amber) turns on when
the system has a malfunction.

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.

When Driving
Because this system detects slight ch anges in tire conditions, the timing
of the warning may be faster or slower in the following cases:
●The size, manufacturer, or the type of tires is different from the specifica-
tion.
●The size, manufacturer, or the type of a tire is different from the others,
or the level of tire wear is excessively different between them.
●A run-flat tire, studless tire, snow tire, or tire chains are used.
●An emergency tire is used (The tire pressure monitoring system warning
light may flash and then continue illuminating).
●A tire is repaired using the emergency flat tire repair kit.
●The tire pressure is excessively hi gher than the specified pressure, or
the tire pressure is suddenly lowered for some reason such as a tire
burst during driving.
●The vehicle speed is lower than about 9.3 mph (15 km/h) (including
when the vehicle is stopped), or t he drive period is shorter than 5 min-
utes.
●The vehicle is driven on an extremely rough road or a slippery, icy road.
●Hard steering and rapid acceleration/deceleration are repeated such as
during aggressive driving on a winding road.
●Load on the vehicle is applied to a tire such as by loading heavy luggage
to one side of the vehicle.
●System initialization has not been im plemented with the specified tire
pressure.
