3-3. Transaxle
Manual Transaxle Operation
The shift pattern of the transaxle
is conventional, as shown.
Depress the clutch pedal all the
way down while shifting; then
release it slowly.
Your vehicle is equipped with a
device to prevent shifting to R
(reverse) by mistake. Push the
shift lever downward and shift to
R.
If shifting to R is difficult, shift back into neutral, release the clutch pedal, and
try again.

WARNING
■Do not use sudden engine braking on slippery road surfaces or at high
speeds
Shifting down while driving on wet, snowy, or frozen roads, or while driving
at high speeds causes sudden engine braking, which is dangerous. The
sudden change in tire speed could cause the tires to skid. This could lead to
loss of vehicle control and an accident.
■ Always leave the shift lever in 1 or R position and set the parking brake
when leaving the vehicle unattended
Otherwise the vehicle could move and cause an accident.

When Driving
■Manually shifting up
●When driving slowly, the gears may not shift up.
● In manual shift mode, do not run the engine with the tachometer needle in
the RED ZONE. When the engine rpm is high, a gear may shift up automat-
ically to protect the engine.
● When depressing the accelerator fully, the transaxle will shift to a lower
gear, depending on vehicle speed.
■ Manually shifting down
●When driving at high speeds, the gear may not shift down.
● During deceleration, the gear may automatically shift down depending on
vehicle speed.
● When depressing the accelerator fully, the transaxle will shift to a lower
gear, depending on vehicle speed.

When Driving
Antilock Brake System (ABS)
The driver will feel a slight vibration in the brake pedal and may hear a
chattering noise from the brake system. This is normal ABS system
operation. Continue to depress the brake pedal without pumping the
brakes.
The warning light turns on when the system has a malfunction.
Refer to Warning Lights on P. 157.
● Braking distances may be longer on loose surfaces (snow or gravel, for
example) which usually have a hard foundation. A vehicle with a normal
braking system may require less distance to stop under these conditions
because the tires will build up a wedge of surface layer when the wheels
skid.
● The sound of the ABS operating may be heard when starting the engine or
immediately after starting the vehicle, however, it does not indicate a mal-
function.
The ABS control unit continuously monitors the speed of each
wheel. If one wheel is about to lock up, the ABS responds by
automatically releasing and reapplying that wheel’s brake.
WARNING
■ Do not rely on ABS as a substitute for safe driving
The ABS cannot compensate for unsafe and reckless driving, excessive
speed, tailgating (following another vehicle too closely), driving on ic\
e and
snow, and hydroplaning (reduced tire friction and road contact because of
water on the road surface). You can still have an accident.

3-6. ABS/TCS/DSC
Traction Control System (TCS)
The warning light turns on when the system has a malfunction.
Refer to Warning Lights on P. 157.
To turn off the TCS, press the DSC OFF switch ( →P. 197).
The Traction Control System (TCS) enhances traction and safety
by controlling engine torque and braking. When the TCS detects
driving wheel slippage, it lowers engine torque and operates the
brakes to prevent loss of traction.
This means that on a slick surface, the engine adjusts automati-
cally to provide optimum power to the drive wheels, limiting
wheel spin and loss of traction.
WARNING
■ Do not rely on the Traction Control System (TCS) as a substitute for
safe driving
The Traction Control System (TCS) cannot compensate for unsafe and
reckless driving, excessive speed, tailgating (following another vehicle too
closely), and hydroplaning (reduced tire friction and road contact because
of water on the road surface). You can still have an accident.
■ Use snow tires or tire chains and drive at reduced speeds when roads
are covered with ice and/or snow
Driving without proper traction devices on snow and/or ice-covered roads is
dangerous. The Traction Control System (TCS) alone cannot provide ade-
quate traction and you could still have an accident.

3-6. ABS/TCS/DSC
Dynamic Stability Control (DSC)
DSC operation is possible at speeds greater than 12 mph (20 km/h).
The warning light turns on when the system has a malfunction.
Refer to Warning Lights on P. 157.
The Dynamic Stability Control (DSC) automatically controls
braking and engine torque in conjunction with systems such as
ABS and TCS to help control side slip when driving on slippery
surfaces, or during sudden or e vasive maneuvering, enhancing
vehicle safety.
Refer to ABS (→ P. 193) and TCS ( →P. 194).
WARNING
■Do not rely on the Dynamic Stabilit y Control as a substitute for safe
driving
The Dynamic Stability Control (DSC) cannot compensate for unsafe and
reckless driving, excessive speed, tailgating (following another vehicle too
closely), and hydroplaning (reduced tire friction and road contact because
of water on the road surface). You can still have an accident.
NOTICE
●The DSC may not operate correctly unless the following are observed:
• Use tires of the correct size specif ied for your Toyota on all four wheels.
• Use tires of the same manufacturer, brand and tread pattern on all four wheels.
• Do not mix worn tires.
● The DSC may not operate correctly when tire chains are used or a tempo-
rary spare tire is installed because the tire diameter changes.

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
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.
