Sounds and vibrations caused by the ABS, brake assist, TRAC 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 ju st 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 system s are
operating. None of these indicates that a malfunction has occur red.
• 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 activa ted.
■ EPS operation sound
When the steering wheel is operated, a motor sound (whirring so und) may
be heard. This does not indicate a malfunction.
■ Automatic reactivation of TRAC and VSC systems
After turning the TRAC and VSC systems off, the systems will be automati-
cally reactivated in the following situations:
● Vehicles without a smart key system: When the engine switch is turned to
“LOCK” position
● Vehicles with a smart key system: When the “ENGINE START STOP”
switch is turned off
● If only the TRAC system is turned off, the TRAC will turn on when vehicle
speed is more than approximately 31 mph (50 km/h).
If both the TRAC and VSC systems are turned off, automatic reac tivation
will not occur when vehicle speed increases.

■Reduced effectiveness of the EPS system
The effectiveness of the EPS system is reduced to prevent the s ystem from
overheating when there is frequent steering input over an exten ded period of
time. The steering wheel may feel heavy as a result. Should thi s occur,
refrain from excessive steering input or stop the vehicle and turn the engine
off. The EPS system should return to normal after a little whil e.
■ Automatic deactivatio n of “TRACK” mode
Vehicles without a smart key system
When the engine switch is turned to “LOCK” position after drivi ng in
“TRACK” mode, the mode is automatically deactivated.
Vehicles with a smart key system
When the “ENGINE START STOP” switch is turned off after driving in
“TRACK” mode, the mode is automatically deactivated.
WARNING
■ The ABS does not operate effectively when
●Tires with inadequate gripping ability are used (such as excess ively worn
tires on a snow covered road).
● The vehicle hydroplanes while driving at high speed on wet or s lick roads.
■ Stopping distance when the ABS is operating may exceed that of nor-
mal 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 in the following situ-
ations:
● 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 potholes or uneven surfaces

Hill-start assist control
Hill-start assist control helps to maintain braking force to assist
starting off forward while facing uphill or starting off backward while
facing downhill. As hill-start assist control is initially disabled,
enable the system to make it operable. The enabled/disabled set ting
will be maintained the next time the engine is started.
The hill-start assist control ON
indicator will be illuminated
when system is enabled and
flash while the system is oper-
ating.
■ Enabling hill-start assist control
Park your vehicle in a flat, safe location.
Make sure that the parking brake is securely engaged.
Stop the engine by turning the engine switch to the “LOCK”
position (vehicles without a smart key system) or turning
the “ENGINE START STOP” switch off (vehicles with a
smart key system).
Start the engine and check t hat the ABS warning light and
slip indicator are off.
Press and hold for
approximately 30 seconds.
Check that both the VSC off

Notes for hill-start assist control
●A slight jolt may be felt when starting off backward with the s hift lever in R
and then moving forward.
● If the braking power of hill-start assist control is insufficient, depress the
brake pedal.
● While the vehicle is stopped, make sure to depress the brake pe dal.
■ The system may be malfunctioning when
In the following situations, the system may be malfunctioning. Have the vehi-
cle inspected by your Toyota dealer.
● The slip indicator is illuminated.
● The hill-start assist control ON indicator turns off and a buzz er sounds.
WARNING
■Hill-start assist control precautions
●Do not overly rely on hill-start assist control. Hill-start ass ist control may
not operate effectively on steep inclines and roads covered wit h ice.
● Unlike the parking brake, hill-start assist control is not inte nded to hold the
vehicle stationary for an extended period of time. Do not attempt to use
hill-start assist control to hold the vehicle on an incline, as doing so may
lead to an accident.
● Do not stop the engine while hill-start assist control is operating, as hill-
start assist control will stop operating, possibly leading to a n accident.

Winter driving tips
Carry out the necessary preparations and inspections before driving
the vehicle in winter. Always drive the vehicle in a manner app ropri-
ate to the prevailing weather conditions.
■ Pre-winter preparations
●Use fluids that are appropriate t o the prevailing outside tem-
peratures.
• Engine oil
• Washer fluid
● Have a service technician inspec t the condition of the battery.
● Have the vehicle fitted with four snow tires.
Make sure to install 4 tires that are of the specified size, an d that
all 4 tires are the same size, same maker, same brand and tread
pattern.
■ Before driving the vehicle
Perform the following accordi ng to the driving conditions.
● Do not try to forcibly open a window or move a wiper that is
frozen. 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 accumulated on the air inlet vents
in front of th e windshield.
● Check for and remove any excess ice or snow that may have
accumulated on the exterior lig hts, 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.

WARNING
■To prevent the windshield from fogging up
Do not set the air outlet selection dial to during cool air op eration in
extremely humid weather. The difference between the temperature of the
outside air and that of the windshield can cause the outer surface of the
windshield to fog up, blocking your vision.
NOTICE
■ To prevent battery discharge
Do not leave the air conditioning system on longer than necessa ry when the
engine is stopped.

■Ventilation and air conditioning odors
●To let fresh air in, set the air conditioning system to the out side air mode.
● During use, various odors from inside and outside the vehicle may enter
into and accumulate in the air conditioning system. This may then cause
odor to be emitted from the vents.
● To reduce potential odors from occurring:
• It is recommended that the air conditioning system be set to outside air
mode prior to turning the vehicle off.
• The start timing of the blower may be delayed for a short peri od of time
immediately after the air conditioning system is started in automatic
mode.
