■Warning message
Some warning messages are
displayed when necessary,
according to certain conditions.
WARNING
■Caution for changing settings
of the head-up display
As the hybrid system needs to be
operating while changing the set-
tings of the head-up display,
ensure that the vehicle is parked
in a place with adequate ventila-
tion. In a closed area such as a
garage, exhaust gases including
harmful carbon monoxide (CO)
may collect and enter the vehicle.
This may lead to death or a seri-
ous health hazard.
NOTICE
■When changing the settings
of the head-up display
To prevent 12-vo lt battery dis-
charge, ensure that the hybrid
system is operating while chang-
ing the settings of the head-up
display.

Driving
pery.
●Drive carefully when it starts to
rain, as the road surface could be
especially slippery.
●Refrain from high speeds when
driving on an expressway in the
rain, because there may be a
layer of water between the tires
and the road surface, preventing
the steering and brakes from
operating properly.
■ECO Accelerator Guidance
(  P.108)
It is easier to drive in an Eco-friendly
manner by driving while referring to
the ECO Accelerator Guidance dis-
play. Also, by using the ECO Accel-
erator 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 accel-
eration is avoid ed, the “Start”
score will increase.
●When driving:
After accelerating to the desired
speed, release the accelerator
pedal and drive at a stable speed
within the ECO Acce lerator Guid-
ance range. By keeping the vehi-
cle within the E CO Accelerator
Guidance range, the “Cruise”
score will increase.
●When stopping:
When stopping the vehicle, early
releasing the accelerator pedal
will cause the “Stop” score to
increase.
■Restraining the hybrid system
output (Brake Override System)
●When the accelerator and brake
pedals 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.471)
■Restraining sudden start (Drive-
Start Control)
●When the following unusual oper-
ation is performed, the hybrid sys-
tem output may b e restrained.
• When the shift lever 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 display and
head-up display (i f equipped). If a
warning message is shown on the
multi-information display and
head-up display (if equipped),
read the message and follow the
instructions.
• When the accelerator pedal is depressed too much while the
vehicle is in reverse.
*: Depending on the situation, the
shift position may not be changed.
●When the TRAC is turned off
( P.336), sudden start restraint
control also does not operate. If
your vehicle have trouble escap-
ing from the mud or fresh snow
due to the sudden start restraint
control operation, deactivate
TRAC( P.336) so that the vehi-
cle may become able to escape
from the mud o r fresh snow.
■Breaking in your new Toyota
To extend the life of the vehicle,
observing the following precautions
is recommended:
●For the first 200 miles (300 km):
Avoid sudden stops.
●For the first 500 miles (800 km):
Do not tow a trailer.
●For the first 600 miles (1000 km):
• Do not drive at extremely high speeds.
• Avoid sudden acceleration.
• Do not drive continuously in low gears.
• Do not drive at a constant speed

WARNING
■Trailer towing precautions
To tow a traile r safely, use
extreme care and drive the vehi-
cle in accordance with the trailer’s
characteristics and operating con-
ditions. Failure to do so could
cause an accident resulting in
death or serious injury. Vehicle
stability and braking performance
are affected by trailer stability,
brake setting and performance,
and the hitch. Your vehicle will
handle differently when towing a
trailer.
■To avoid accident or injury
●Do not exceed the TWR,
unbraked TWR, GCWR, GVWR
or GAWR.
●Vehicles without spare tire: Do
not tow a trailer when the tire
installed is re paired with the
emergency tire puncture repair
kit.
●If the gross trailer weight is over
2000 lb. (907 kg), a sway con-
trol device with sufficient capac-
ity is required.
●Adjust the tongue weight within
the appropriate range. Place
heavier loads as close to the
trailer axle as possible.
●Do not exceed 65 mph (104
km/h), the posted towing speed
limit or the speed limit for your
trailer as set fort h in your trailer
owner’s manual, whichever is
lowest. Slow down sufficiently
before making a turn, in cross
winds, on wet or slippery sur-
face, etc. to help avoid an acci-
dent. If you experience a
vehicle-trailer instability from
reducing a certain speed, slow
down and make sure you keep
your vehicle speed under the
speed of which you experience
the instability.
●Do not make jer ky, abrupt or
sharp turns.
●Do not apply the brakes sud-
denly as you may skid, resulting
in jackknifing and loss of vehicle
control. This is especially true
on wet or slippery surfaces.
●Do not exceed the trailer hitch
assembly weight, gross vehicle
weight, gross axle weight and
trailer tongue w eight capacities.
●Do not use dynamic radar
cruise control with full-speed
range when towing.
●Slow down and downshift
before descending steep or long
downhill grades. Do not make
sudden downshifts while
descending steep or long down-
hill grades.
●Vehicle-trailer in stability is more
likely on steep long downhills.
Before descending steep or
long downhill grades, slow
down and downshift. Do not
make sudden downshifts when
descending steep or long down-
hill grades. Avoid holding the
brake pedal down too long or
applying the brakes too fre-
quently. This could cause the
brakes to overheat and result in
reduced braking efficiency.
●Vehicles with compact spare
tire: Do not tow a trailer when
the compact spare tire is
installed on your vehicle.
■When towing a trailer
Toyota recommends trailers with
brakes that conform to any appli-
cable federal and s tate/provincial
regulations.
