5-4. Using the driving support systems
WARNING
●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.
■When the TRC/ABS/VSC/Trailer Sway Control is activated
The slip indicator light flashes. Always drive carefully. Reckless driving may cause an accident. Exercise particular
care when the indicator light flashes.
■When the TRC/VSC/Trailer Sway
Control 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/Trailer Sway Control sys- tems off unless necessary.Trailer Sway Control is part of the
VSC system and will not operate if VSC is turned off or experiences a malfunction.
■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, VSC and Trailer
Sway Control systems will not func- tion 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.
■Trailer Sway Control precaution
The Trailer Sway Control system is
not able to reduce trailer sway in all situations. Depending on many fac-tors such as the conditions of the
vehicle, trailer, road surface and driv- ing environment, the Trailer Sway Control system may not be effective.
Refer to your trailer owner’s manual for information on how to tow your trailer properly.
■If trailer sway occurs
Observe the following precautions.
Failing to do so may cause death or serious injury.
●Firmly grip the steering wheel. Steer straight ahead. Do not try to control trailer swaying by turning
the steering wheel.
●Begin releasing the accelerator
pedal immediately but very gradu- ally to reduce speed. Do not increase speed. Do not apply vehi-
cle brakes. If you make no extreme correction with the steering or brakes, your
vehicle and trailer should stabilize. ( P.237)
■Secondary Collision Brake
Do not rely solely upon the Secondary Collision Brake. This system is
designed to help reduce the possibil- ity of further damage due to a second-ary collision, however, that effect
changes according to various condi- tions. Overly relying on the system may result in death or serious injury.

5-5. Driving tips
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.
Accelerate the vehicle slowly, keep
a safe distance between you and
the vehicle ahead, and drive at a
reduced speed suitable to road
conditions.
 Turn automatic mode of the park-
ing brake off. Otherwise, the
parking brake may freeze and
not be able to be released auto-
matically.
Also, avoid using the following as the
parking brake may operate automati-
cally, even if automatic mode is off.
• Brake hold system
• Remote parking function
 Park the vehicle and shift the
shift position to P without setting
the parking brake. The parking
brake may freeze up, preventing
it from being released. If the
vehicle is parked without setting
the parking 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.
When the parking brake is in
automatic mode, release the
parking brake after shifting the
shift position to P. ( P.255)
 If the vehicle is parked without
setting the parking brake, con-
firm that the shift position cannot
be moved out of P.
 If the vehicle is left parked with
the brakes damp in cold tem-
peratures, there is a possibility of
the brakes freezing.
Use the correct tire chain size when
mounting the tire chains. Chain size

●To let fresh air in, set the air condition-
ing system to the outside 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 occur-
ring: • It is recommended that the air condi-tioning 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 period of time
immediately after the air conditioning system is started in automatic mode.
