4205-5. Using the driving support systems
WARNING
■TRC/VSC may not operate effec- tively when
Directional control and power may not be achievable while driving on slip-pery road surfaces, even if the
TRC/VSC system is operating. Drive the vehicle carefully in condi-tions where stability and power may
be lost.
■Active Cornering Assist does not
operate effectively when
●Do not overly rely on Active Corner- ing Assist. Active Cornering Assist
may not operate effectively when accelerating down slopes or driving on slippery road surfaces.
●When Active Cornering Assist fre-quently operates, Active Cornering
Assist may temporarily stop operat- ing to ensure proper operation of the brakes, TRC and VSC.
■Hill-start assist control does not operate effectively when
●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.
■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.

5-6. Driving tips
Driving
Perform 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, outside rear view mir-
rors, windows, 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
parking 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
 Park the vehicle and shift the
shift lever 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 park-
ing brake, make sure to block the
wheels. Failure to do so may be
dangerous because it may cause
the vehicle to move unexpect-
edly, possibly leading to an acci-
dent.
 When the parking brake is in
automatic mode, release the
parking brake after shifting the
shift lever to P. ( P.321)
 If the vehicle is parked without
setting the parking brake, con-
firm that the shift lever 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.
