wheel TOYOTA VERSO S 2011 Repair Manual

3805-5. Using the driving support systems
When a vehicle is detected running ahead of you, the system automatically deceler-
ates your vehicle. When a greater reduction in vehicle speed is necessary, the sys-
tem applies the brakes (the stop lights will come on at this time). The system will
respond to changes in the speed of the vehicle ahead in order to maintain the vehi-
cle-to-vehicle distance set by the driver. Approach warning warns you when the sys-
tem cannot decelerate sufficiently to prevent your vehicle from closing in on the
vehicle ahead.
When the vehicle ahead of you stops, your vehicle will also stop (vehicle is stopped
by system control). After the vehicle ahead starts off, pressing the “+RES” switch or
depressing the accelerator pedal (start-off operation) will resume follow-up cruising.
If the start-off operation is not performed, system control continues to keep your
vehicle stopped.
When the turn signal lever is operated and your vehicle moves to an overtaking lane
while driving at 50 mph (80 km/h) or more, the vehicle will accelerate to help to over-
take a passing vehicle.
The system’s identification of what is an overtaking lane may be determined solely
based on the location of the steering wheel in the vehicle (left side driver position
versus right side driver position.) If the vehicle is driven to a region where the over-
taking lane is on a different side from where the vehicle is normally driven, the vehi-
cle may accelerate when the turn signal lever is operated in the opposite direction to
the overtaking lane (e.g., if the driver normally operates the vehicle in a region
where the overtaking lane is to the right but then drives to a region where the over-
taking lane is to the left, the vehicle may accelerate when the right turn signal is acti-
vated).
Example of acceleration
When there are no longer any preceding vehicles driving slower than the
set speed
The system accelerates until the set speed is reached. The system then returns to
constant speed cruising.
1Press the cruise control main
switch to activate the cruise con-
trol.
Dynamic radar cruise control indicator
will come on and a message will be dis-
played on the multi-information display.
Press the switch again to deactivate the
cruise control.If the cruise control main switch is
pressed and held for 1.5 seconds or
more, the system turns on in constant

●Trail Mode controls the vehicle so that
it can use the maximum amount of
drive force when driving on bumpy
roads.
●If Trail Mode is continuously used for
a long period of time, the load on
related parts increases and the sys-
tem may be unable to operate effec-
tively.
■When Trail Mode is canceled
In the following situations, Trail Mode is
automatically canceled even if it is
turned on.
●When the driving mode is changed
(P.434)

●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

WARNING
●When driving over roads with pot- holes or uneven surfaces
■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 and VSC/Trailer Sway Control systems will not function cor-rectly 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.

4445-5. Using the driving support systems
WARNING
■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 vehicle brakes.
If you make no extreme correction
with the steering or brakes, your vehi-
cle and trailer should stabilize.
( P.308)
■Secondary Collision Brake (if
equipped)
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.
