2021 TOYOTA RAV4 PHEV warning

3785-5. Using the driving support systems
WARNING
■Cautions regarding the driving
assist systems
Observe the following precautions, as there are limitations to the assistance
provided by the syst em. Failure to do
so may cause an accident resulting in death or serious injury.
●Assisting the driver to measure fol -
lowing distance
The dynamic radar cruise control with
full-speed range is only intended to
help the driver in determining the fol -
lowing distance bet ween the driver’s
own vehicle and a designated vehicle
traveling ahead. It is not a mechanism
that allows carele ss or inattentive
driving, and it is not a system that can
assist the driver in low-visibility condi-
tions.
It is still necessary for driver to pay
close attention to the vehicle’s sur -
roundings.
●Assisting the driver to judge proper
following distance
The dynamic radar cruise control with
full-speed range determines whether
the following dist ance between the
driver’s own vehicle and a designated
vehicle traveling ahead is within a set
range. It is not capable of making any
other type of judgemen t. Therefore, it
is absolutely necessary for the driver
to remain vigilant and to determine
whether or not there is a possibility of
danger in any given situation.
●Assisting the driver to operate the vehicle
The dynamic radar cruise control with
full-speed range does not include
functions which will prevent or avoid
collisions with vehi cles ahead of your
vehicle. Therefore, if there is ever any
possibility of danger, the driver must
take immediate and direct control of
the vehicle and act appropriately in
order to ensure the safety of all
involved.
■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.)

Driving
This mode employs a radar to detect the presence of vehicles up to approx-
imately 100 m (328 ft.) ahead, det ermines the current vehicle-to-vehicle fol-
lowing distance, and operates to m aintain a suitable following distance from
the vehicle ahead. The desired v ehicle-to-vehicle distance can also be set
by operating the vehicle-to -vehicle distance switch.
When driving on downhill slopes, the vehicle-to-vehicle distance may become
shorter.
Example of constant speed cruising
When there are no vehicles ahead
The vehicle travels at the speed set by the driver.
Example of deceleration cruising and follow-up cruising
When a preceding vehicle driving slower than the set speed appe ars
WARNING
●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
●When your vehicle is towing a
trailer or during emergency towing
●When an approach warning buzzer
is heard often

3805-5. Using the driving support systems
When a vehicle is de tected running ahead of you, the system automatically deceler-
ates your vehicle. When a great er 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 war ns 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 sto p (vehicle is stopped
by system control). After the veh icle ahead starts off, pressing the “+RES” switch or
depressing the accelerator pedal (start-off operation) will res ume 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 t o an overtaking lane
while driving at 50 mph (80 km/h) or more, the vehicle will acc elerate to help to over-
take a passing vehicle.
The system’s identificat ion of what is an overtaking lane may be determined solely
based on the location of the ste ering wheel in the vehicle (left side driver position
versus right side driv er position.) If the vehicle is driven to a region where the over-
taking lane is on a different sid e from where the vehicle is normally driven, the vehi-
cle may accelerate when the turn signal lever is operated in th e opposite direction to
the overtaking lane (e.g., if th e driver normally operates the vehicle in a region
where the overtaking lane is to t he 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.
1 Press 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 tur ns on in constant

Driving
1 Pressing the cancel switch can-
cels the speed control.
The speed control is also canceled
when the brake pedal is depressed.
(When the vehicle has been stopped by
system control, depr essing the brake
pedal does not cancel the setting.)
2 Pressing the “+RES” switch
resumes the cruise control and
returns vehicle speed to the set
speed.
When your vehicle is too close to a
vehicle ahead, and sufficient auto-
matic deceleration via the cruise
control is not possible, the display
will flash and the buzzer will sound
to alert the driver. An example of
this would be if ano ther driver cuts
in front of you whi le you are follow-
ing a vehicle. Depress the brake
pedal to ensure an appropriate
vehicle-to-vehicle distance.
■Warnings may not occur when
In the following instances, warnings
may not occur even when the vehi -
cle-to-vehicle d istance is small.
 When the speed of the preceding
vehicle matches or exceeds your
vehicle speed
 When the preceding vehicle is
traveling at an extremely slow
speed
 Immediately after the cruise con-
trol speed was set
 When depressing the accelerator
pedal
When constant speed control mode
is selected, your vehicle will main-
tain a set speed without controlling

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 ar e 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 messa ge and follow the
instructions. ( →P.353, 578)
■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 ope rate 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.383) may not be
activated.
●Vehicles that cut in suddenly
●Vehicles traveling at low speeds
●Vehicles that are not moving in the same lane
●Vehicles with small rear ends (trailers with no load on board, etc.)
●Motorcycles traveling in the same lane
●When water or snow thrown up by the
surrounding vehicles hinders the detecting of the sensor
●When your vehicle is pointing
upwards (caused by a heavy load in the luggage compartment, etc.)
