■Driving in the rain
●Drive carefully when it is raining,
because visibility will be reduced, the
windows may become fogged-up, and the road could be slippery.
●Drive carefully when it starts to rain, as the road surfa ce could be espe-
cially slippery.
●Refrain from hig h speeds when driv-
ing on an expressw ay in the rain,
because there may be a layer of water between the tires and the road sur -
face, preventing the steering and
brakes from operating properly.
■ECO Accelerator Guidance ( →P.182)
It is easier to drive in an Eco-friendly
manner by driving while referring to the ECO Accelerator Guidance display.
Also, by using the ECO Accelerator
Guidance it is easier to increase the “Eco Score” evaluation.
●When starting off: While staying within the ECO Accelerator Guidance range,
gradually depress the accelerator
pedal and accelerate to the desired speed. If excessive acceleration is
avoided, the “Start” score will
increase.
●When driving: After accelerating to the
desired speed, release the accelera - tor pedal and drive at a stable speed
within the ECO Accelerator Guidance
range. By keeping the vehicle within the ECO Accelerator Guidance range,
the “Cruise” score will increase.
●When stopping: When stopping the
vehicle, early releasing the accelera -
tor pedal will cause the “Stop” score to increase.
■Restraining the hybrid system out - put (Brake Override System)
●When the accelerator and brake ped - als are depressed at the same time,
the hybrid system output may be
restrained.
●A warning message is displayed on
the multi-information display and
head-up display (if equipped) while
the system is operating. ( →P.574)
■Restraining sudden start (Drive- Start Control)
●When the following unusual operation is performed, the hybrid system output
may be restrained.
• When the shift leve r is shifted from R
to D, D to R, N to R, P to D*, or P to R*
(D includes S) with the accelerator
pedal depressed, a warning message appears on the multi-information dis -
play and head-up display (if
equipped). If a warning message is shown on the multi-information dis -
play, read the message and follow the
instructions. • When the accelerator pedal is
depressed too much while the vehicle
is in reverse.*: Depending on the sit uation, the shift
lever may not be changed.
●While Drive-Start Control is being acti -
vated, your vehicle may have trouble escaping from the mud or fresh snow.
In such case, deactivate TRC
( →P.439) to cancel Drive-Start Con- trol so that the vehi cle may be able to
escape from the mud or fresh snow.
●Drive-Start Control does not work
when Trail Mode is turned on.
■Breaking in your new Toyota
To extend the life of the vehicle, observ- ing the following precautions is recom -
mended:
●For the first 300 km (200 miles):
Avoid sudden stops.
●For the first 800 km (500 miles):
Do not tow a trailer.
●For the first 1000 km (600 miles): • Do not drive at extremely high
speeds.

WARNING
■Before using dynamic radar
cruise control with full-speed
range
●Driving safely is the sole responsi -
bility of the driver. Do not rely solely
on the system, and drive safely by always paying careful attention to
your surroundings.
●The dynamic radar cruise control
with full-speed range provides driv -
ing assistance to reduce the driver’s burden. However, there are
limitations to the assistance pro -
vided.
Read the following conditions care -
fully. Do not overly rely on this system
and always drive carefully.

• Conditions under which the vehicle- to-vehicle distance control mode
may not function correctly: →P.387
●Set the speed appropriately
depending on the speed limit, traffic
flow, road conditions, weather con - ditions, etc. The driver is responsi -
ble for checking the set speed.
●Even when the system is function -
ing normally, the condition of the
preceding vehicle as detected by the system may differ from the con -
dition observed by the driver.
Therefore, the dri ver must always remain alert, assess the danger of
each situation and drive safely.
Relying solely on this system or assuming the system ensures
safety while driving can lead to an
accident, resulti ng in death or seri- ous injury.
●Switch the dynamic radar cruise control with full-speed range setting
to off, using the cruise control main
switch when not in use.

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.)
