WARNING
■Situations unsuitable for dynamic radar cruise control
with full-speed range
Do not use dynamic radar cruise con- trol with full-speed range in any of the
following situations. Doing so may result in inappropriate speed control and could cause an accident resulting
in death or serious injury.
●Roads where there are pedestrians,
cyclists, etc.
●In heavy traffic
●On roads with sharp bends
●On winding roads
●On slippery roads, such as those
covered with rain, ice or snow
●On steep downhills, or where there
are sudden changes between sharp up and down gradients
Vehicle speed may exceed the set
speed when driving down a steep hill.
●At entrances to freeways and high- ways
●When weather conditions are bad enough that they may prevent the
sensors from detecting correctly (fog, snow, sandstorm, heavy rain, etc.)
●When there is rain, snow, etc., on the front surface of the radar or
front camera
●In traffic conditions that require fre-
quent repeated acceleration and deceleration

If constant speed control mode is auto- matically canceled for any reasons other
than the above, there may be a malfunc- tion in the system. Contact any autho-rized Toyota retailer or Toyota
authorized repairer, or any reliable repairer.
■The Dynamic Radar Cruise Control with Road Sign Assist may not
operate properly when (if equipped)
As the Dynamic Radar Cruise Control
with Road Sign Assist may not operate properly in conditions in which RSA may not operate or detect correctly
( P.247), when using this function, make sure to check the speed limit sign displayed.
In the following situations, the set speed may not be changed to the recognized speed limit by pressing and holding the
“+RES”/“-SET” switch.
●If speed limit information is not avail-
able
●When the recognized speed limit is
the same as the set speed
●When the recognized speed limit is
outside of the speed range that the dynamic radar cruise control system can operate
■Brake operation
A brake operation sound may be heard and the brake pedal response may
change, but these are not malfunctions.
■Warning messages and buzzers for
dynamic radar cruise control with full-speed range
Warning messages and buzzers are
used to indicate a system malfunction or to inform the driver of the need for cau-tion while driving. If a warning message
is shown on the multi-information dis- play, read the message and follow the instructions. ( P.207, 383)
■When the sensor may not be cor-
rectly detecting the vehicle ahead
In the case of the following and depend- ing on the conditions, operate the brake
pedal when deceleration of the system is insufficient or operate the accelerator pedal when acceleration is required.
As the sensor may not be able to cor- rectly detect these types of vehicles, the approach warning ( P.237) may not be
activated.

4-5. Using the driving support systems
*: If equipped
The RSA system recognizes spe-
cific road signs using the front cam-
era and/or 7-inch/8-inch display
navigation system (when speed
limit information is available) to pro-
vide information to the driver via the
display.
If the system judges that the vehicle
is being driven over the speed limit,
performing prohibited actions, etc.,
according to the recognized road
signs, it notifies the driver through a
visual notification and notification
buzzer.
WARNING
■To avoid operating the speed lim- iter by mistake
Switch the speed limiter off using the speed limiter main switch when not in use.
■Situations unsuitable for speed limiter
Do not use speed limiter in any of the following situations.Doing so may result in loss of control
and could cause an accident resulting in death or serious injury.
