■Hill-start assist control precau- tions
●Do not overly rely on hill-start assist
control. Hill-start assist control may not operate effectively on steep
inclines and roads covered with ice.
●Unlike the parking brake, hill-start
assist control is not intended to hold
the vehicle stationary for an extended period of time. Do not
attempt to use hill-start assist con-
trol to hold the vehicle on an incline, as doing so may lead to an acci-
dent.
●Do not stop the engine while
hill-start assist control is operating,
as hill-start assist control will stop operating, possibly leading to an
accident.
Exhaust Gas Filter sys-
tem*
The Exhaust Gas Filter system
is designed to collect particu-
late matter in the exhaust
gases using an exhaust gas fil-
ter installed to the exhaust
pipes.
NOTICE
■To prevent the Exhaust Gas Filter
system from failing
●Do not use fuel other than the spec- ified type
●Do not modify the exhaust pipe

■ABS (Anti-lock Brake System)
Helps to prevent wheel lock when
the brakes are applied suddenly, or
if the brakes are applied while driv-
ing 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 St ability 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
The TRC system is also equipped
with the brake LSD function.
■Hill-start assist control
 P.253
■EPS (Electric Power Steering)
Employs an electric motor to
reduce the amount of effort needed
to turn the steering wheel
■Emergency brake signal
When the brakes are applied sud-
denly, the emergency flashers auto-
matically flash to alert the vehicle
behind.
■When the TRC/VSC systems are
operating
The slip indicator will flash while the TRC (Including brake LSD func-
tion)/VSC systems are operating.
■Disabling the TRC system
If the vehicle gets stuck in mud, dirt or
snow, the TRC system may reduce
power from the engine to the wheels.
Pressing switch to turn the system
off may make it easier for you to rock the
vehicle in order to free it.
In this case, the brake LSD function
remains on.
To turn the TRC system off, quickly
press and release switch.

ous driving preferences. The control
modes can be selected with the “TRACK” switch. Normal mode allows
secure and smooth normal driving.
When the switch is pressed and held for 1 second or more, “TRACK” mode is
activated. When “TRACK” mode is
selected, the control characteristics of VSC, TRC, etc. will be changed and
sportier than normal driving will be pos-
sible.
When “TRACK” mode is selected, the
multi-information display will change to
the “TRACK” mode display and the “TRACK” indicator and VSC OFF indica-
tor will illuminate.

■Sounds and vibrations caused by
the ABS, brake assist, TRC and
VSC systems
●A sound may be heard from the
engine compartment when the brake pedal is depressed repeatedly, when
the engine is started or just after the
vehicle begins to move. This sound does not indicate that a malfunction
has occurred in any of these systems.
●Any of the following conditions may
occur when the above systems are
operating. None of these indicates that a malfunction has occurred.
• Vibrations may be felt through the
vehicle body and steering. • A motor sound may be heard after the
vehicle comes to a stop.
• The brake pedal may pulsate slightly after the ABS is activated.
• The brake pedal may move down
slightly after the ABS is activated.
■EPS operation sound
When the steering wheel is operated, a
motor sound (whirring sound) may be
heard. This does not indicate a malfunc- tion.
■Automatic reactivation of TRC and
VSC systems
After turning the TRC and VSC systems off, the systems will be automatically
reactivated in the following situations:
●When the engine switch is turned off.
●If only the TRC system is turned off, the TRC will turn on when vehicle
speed is more than approximately 50
km/h (31 mph).
If both the TRC and VSC systems are turned off, automatic reactivation will
not occur when vehicle speed
increases.
■Reduced effectiveness of the EPS system
The effectiveness of the EPS system is
reduced to prevent the system from
overheating when there is frequent
steering input over an extended period
of time. The steering wheel may feel heavy as a result. Should this occur,
refrain from excessive steering input or
stop the vehicle and turn the engine off. The EPS system should return to nor-
mal after a little while.
■Automatic deactivation of
“TRACK” mode
When the engine switch is turned off
after driving in “TRACK” mode, the
mode is automatically deactivated.
■Operating conditions of emergency brake signal
When the following three conditions are
met, the emergency brake signal will operate:
●The emergency flashers are off.
●Actual vehicle speed is over 60 km/h
(38 mph).
●The brake pedal is depressed in a
manner that cause the system to judge from the vehicle deceleration
that this is a sudden braking opera-
tion.
■Automatic system cancelation of emergency brake signal
The emergency brake signal will turn off
in any of the following situations:
●The emergency flashers are turned
on.
●The brake pedal is released.
●The system judges from the vehicle
deceleration that is not a sudden brak-
ing operation.
■Customization
Some functions can be customized. ( P.377)

■The ABS does not operate effec-
tively when
●The limits of tire gripping perfor- mance have been exceeded (such
as excessively worn tires on a snow
covered road).
●The vehicle hydroplanes while driv-
ing at high speed on wet or slick
roads.
■Stopping distance when the ABS
is operating may exceed that of normal conditions
The ABS is not designed to shorten
the vehicle’s stopping distance. Always maintain a safe distance from
the vehicle in front of you, especially
in the following situations:
●When driving on dirt, gravel or
snow-covered roads
●When driving with tire chains
●When driving over bumps in the
road
●When driving over roads with pot-
holes or uneven surfaces
■TRC may not operate effectively
when
Directional control and power may not be achievable while driving on slip-
pery road surfaces, even if the TRC
system is operating. Do not drive the vehicle in conditions where stability
and power may be lost.
■When the VSC and/or brake LSD
function is activated
The slip indicator flashes. Always drive carefully. Reckless driving may
cause an accident. Exercise particular
care when the indicator flashes.
■When the TRC/VSC systems are turned off
Be especially careful and drive at a
speed appropriate to the road condi- tions. As these are the systems to
help ensure vehicle stability and driv-
ing force, do not turn the TRC/VSC systems off unless necessary.
■Replacing tires
Make sure that all tires are of the
specified size, brand, tread pattern
and total load capacity. In addition, make sure that the tires are inflated to
the recommended tire inflation pres-
sure level.
The ABS, TRC and VSC systems will
not function correctly if different tires
are installed on the vehicle. Contact any authorized Toyota retailer
or Toyota authorized repairer, or any
reliable repairer for further information when replacing tires or wheels.
■Handling of tires and the suspen-sion
Using tires with any kind of problem
or modifying the suspension will affect the driving assist systems, and may
cause a system to malfunction.

■Driving with snow tires
Observe the following precautions to
reduce the risk of accidents.
Failure to do so may result in a loss of vehicle control and cause death or
serious injury.
●Use tires of the specified size, and that are the same size, same
maker, same brand and tread pat-
tern.
●Maintain the recommended level of
air pressure.
●Do not drive at speeds in excess of
the speed limit or the speed limit specified for the snow tires being
used.
●Use snow tires on a ll, not just some
wheels.
■Driving with tire chains
●When any of the tires are punc-
tured, you can seal the tire tempo- rarily. However, do not use the tire
chain on a sealed tire. If any of the
rear tires are punctured although it is required to use tire chains, con-
tact any authorized Toyota dealer or
repairer, or another duly qualified and equipped professional.
●Observe the following precautions to reduce the risk of accidents.
Failure to do so may result in the
vehicle being unable to be driven safely, and may cause death or
serious injury.
• Do not drive in excess of the speed limit specified for the tire chains
being used, or 30 km/h (19 mph),
whichever is lower.
• Avoid driving on bumpy road sur-
faces or over potholes.
• Avoid sudden acceleration, abrupt
steering, sudden braking and shift- ing operations that cause sudden
engine braking.
• Slow down sufficiently before enter- ing a curve to ensure that vehicle
control is maintained.

4-7. Driving tips
DrivingPerform the following according to
the driving conditions:
 Do not try to forcibly open a win-
dow or move a wiper that is fro-
zen. Pour warm water over the
frozen area to melt the ice. Wipe
away the water immediately to
prevent it from freezing.
 To ensure proper operation of
the climate control system fan,
remove any snow that has accu-
mulated on the air inlet vents in
front of the windshield.
 Check for and remove any
excess ice or snow that may
have accumulated on the exte-
rior lights, vehicle’s roof, chassis,
around the tires or on the brakes.
 Remove any snow or mud from
the bottom of your shoes before
getting in the vehicle.
 If a door is opened and closed
when its side window is frozen,
the window safety device will
operate and the side window
open/close function linked to
door operation may not operate
correctly. If this occurs, perform
the following after the ice has
melted.
After opening the window to the
approximately half open position,
perform initialization. ( P.126)
Accelerate the vehicle slowly, keep
a safe distance between you and
the vehicle ahead, and drive at a
reduced speed suitable to road
conditions.
 Park the vehicle and shift the
shift lever to P (automatic trans-
mission), or 1 or R (manual
transmission) with out setting the
parking brake. The parking brake
may freeze up, preventing it from
being released. If the vehicle is
parked without setting the park-
ing brake, make sure to block the
wheels.
Failure to do so may be danger-
ous because it may cause the
vehicle to move unexpectedly,
possibly leading to an accident.
