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 Contact Your Toyota Dealer and Have Vehicle Inspected on
P. 493.
The Dynamic Stability Control ( DSC) automatically controls
braking and engine torque in c onjunction with systems such as
ABS and TCS to help control si de slip when driving on slippery
surfaces, or during sudden or e vasive maneuvering, enhancing
vehicle safety.
Refer to ABS ( P. 215) and TCS ( P. 216).
WARNING
■Do not rely on the Dynamic Stabil ity Control as a substitute for safe
driving
The Dynamic Stability Control (DSC) cannot compensate for unsaf e and
reckless driving, excessive speed, tailgating (following anothe r 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 obse rved:
• Use tires of the correct size specified for your Toyota on all 4 wheels.
• Use tires of the same manufacturer, brand and tread pattern on all 4 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.

3-8. Drive Selection
Drive Selection (Automatic Transaxle)
●When the sport mode is selected, driving at higher engine speed s 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
• Cruise control 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.
●In the following cases, the drive selection is canceled.
• The ignition is switched OFF.
• Cruise control is set.
● Depending on the driving conditions when sport mode is selected , the vehi-
cle may perform shift-down or slightly accelerate.
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 enhanc ed. This provides additional
quick acceleration which may be needed to safely make maneu-
vers such as lane changes, merging onto free ways, or passing
other vehicles.
WARNING
Do not use the sport mode when driving on slippery roads such a s wet or
snow-covered roads. It may cause tire slipping.

3-9. Power Steering
Power Steering
• Power steering is only operable when the engine is running. If the
engine is off or if the power steering system is inoperable, you can
still steer, but it require s 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 driver of system abnormalities and
operation conditions.
In addition, the buzzer may als o activate depending on the syst em
abnormality or operation condition.
Refer to Stop Vehicl e in Safe Place Imme diately on P. 489.
Refer to Power Steering Warning Buzzer on P. 505.
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.

minate.
• The vehicle speed is between about 2 to 18 mph (4 to 30 km/h).
• The Low Speed Pre-Collision System is not turned off.
• The DSC is not malfunctioning.
● The Low Speed Pre-Collision System 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. Co nsequently,
the Low Speed Pre-Collision System may not operate under the following
conditions:
• Reflection of the laser is poor due to the shape of the vehicl e 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 extreme ly low or
high profile.
• Vehicles with certain shapes such as a vehicle carrier.
● Under the following conditions, the Low Speed Pre-Collision Sys tem may
not operate normally.
• Heavy luggage is loaded in the luggage compartment or on the r ear seat.
• If there is the possibility of partial contact with a vehicle ahead.
• When driving on continuously curving roads, and entering and e xiting
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 v apor rising
from manholes and grating, and water splashed into the air.

When Driving
WARNING
■Do not rely on the Low Speed Pre -Collision System as a substitute for
safer driving
The Low Speed Pre-Collision System cannot compensate for unsafe and
reckless driving, excessive speed, tailgating (following anothe r 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 sur-
face). You can still have an accident.
■ Do not rely completely on the Low Speed Pre-Collision System
● The Low Speed Pre-Collision System is only designed to reduce d amage
in the event of a collision. Over reliance on the system leadin g to the
accelerator pedal or brake pedal being mistakenly operated coul d result in
an accident.
● The Low Speed Pre-Collision System 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 Low Speed Pre-Collision System is inst alled near
the rearview mirror. To assure the correct operation of the Low Speed Pre-
Collision System, heed the following cautions.
• Do not apply stickers to the surface of the windshield near the laser sensor (including transparent stickers). Otherwise, the laser s ensor
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 l aser 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 visib le near
the laser sensor, stop using the Low Speed Pre-Collision System
immediately and have your vehicle inspected by your Toyota deal er. If
the vehicle continues to be driven with cracks or scratch marks left on
the windshield near the laser sensor, the system may operate un nec-
essarily and cause an unexpected accident.
Refer to Stopping The Low Speed Pre-Collision System Operation on
P. 2 3 3 .
• When replacing the windshield wi pers 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 a nd may
not be able to operate normally. Always drive carefully and pay attention to
the road ahead.

When Driving
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 b e ini-
tialized with the specified tire pressure (value on the tire pressure
label). Follow the procedure and perform the initialization.
Refer to Tire Pressure Monitorin g System Initialization on P. 244.
The warning light flashes when the system has a malfunction.
Refer to Warning Lights on P. 173.
: If equipped
The Tire Pressure Monitoring S ystem (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.
