WARNING
●If the vehicle is stopped on an
incline, in order to prevent acci-
dents caused by the vehicle roll-
ing forward or backward, always
depress the brake pedal and
securely apply the parking
brake as needed.
●Avoid revving or racing the
engine.
Running the engine at high
speed while the vehicle is
stopped may cause the exhaust
system to overheat, which could
result in a fire if combustible
material is nearby.
■When the vehicle is parked
●Do not leave glasses, cigarette
lighters, spray cans, or soft
drink cans in the vehicle when it
is in the sun.
Doing so may result in the fol-
lowing:
• Gas may leak from a cigarette lighter or spray can, and may
lead to a fire.
• The temperature inside the vehicle may cause the plastic
lenses and plastic material of
glasses to deform or crack.
• Soft drink cans may fracture, causing the contents to spray
over the interior of the vehicle,
and may also caus e a short cir-
cuit in the vehicle’s electrical
components.
●Do not leave cigarette lighters in
the vehicle. If a cigarette lighter
is in a place such as the glove
box or on the floor, it may be lit
accidentally when luggage is
loaded or the seat is adjusted,
causing a fire.
●Do not attach adhesive discs to
the windshield or windows. Do
not place containers such as air
fresheners on the instrument
panel or dashboard. Adhesive
discs or containers may act as
lenses, causing a fire in the
vehicle.
●Do not leave a door or window
open if the curved glass is
coated with a metallized film
such as a silver-colored one.
Reflected sunlight may cause
the glass to act a s a lens, caus-
ing a fire.
●Always apply the parking brake,
shift the shift lever to P, stop the
hybrid system and lock the vehi-
cle. Do not leave the vehicle
unattended while the hybrid
system is operating.
If the vehicle is parked with the
shift lever in P but the parking
brake is not set, the vehicle may
start to move, possibly leading
to an accident.
●Do not touch the exhaust pipes
while the “READY” indicator is
illuminated or immediately after
turning the hybrid system off.
Doing so may cause burns.
●4WD models: If the shift lever is
moved before the “4L” indicator
turns on/off, the transfer mode
may not be shifted completely.
The transfer mode disengages
both the front and rear drivesh-
afts from the p owertrain and
allows the vehicle to move
regardless of the shift position.
(At this time, the indicator blinks
and the buzzer sounds.)
Therefore, the vehicle is free to
roll even if the automatic trans-
mission is in P. You or someone
else could be seriously injured.
You must complete the shifting
of the transfer mode. ( P.361)

WARNING
■When taking a nap in the vehi-
cle
Always turn the hybrid system off.
Otherwise, if you accidentally
move the shift lever or depress
the accelerator pedal, this could
cause an accident or fire due to
hybrid system overheating. Addi-
tionally, if the vehicle is parked in
a poorly ventilated area, exhaust
gases may collect and enter the
vehicle, leading to death or a seri-
ous health hazard.
■When braking
●When the brakes a re wet, drive
more cautiously.
Braking distance increases
when the brakes are wet, and
this may cause one side of the
vehicle to brake differently than
the other side. Also, the parking
brake may not securely hold the
vehicle.
●If the electroni cally controlled
brake does not operate, do not
follow other vehicl es closely and
avoid hills or sharp turns that
require braking.
In this case, braking is still pos-
sible, but the brake pedal
should be depressed more
firmly than usual. Also, the brak-
ing distance will increase. Have
your brakes fixed immediately.
●The brake system consists of 2
or more individual hydraulic sys-
tems; if one of the systems fails,
the other will still operate. In this
case, the brake pedal should be
depressed more firmly than
usual and the braking distance
will increase. Have your brakes
fixed immediately.
■If the vehicle becomes stuck
Do not spin the wheels exces-
sively when a driven wheel is up
in the air, or the vehicle is stuck in
sand, mud, etc. This may damage
the driveline components or pro-
pel the vehicle forward or back-
ward, causing an accident.
NOTICE
■When driving the vehicle
●Do not depress the accelerator
and brake pedals at the same
time during driving, as this may
restrain the hybrid system out-
put.
●Do not use the accelerator
pedal or depress the accelera-
tor and brake pedals at the
same time to hold the vehicle on
a hill.
■When parking the vehicle
Always set the parking brake and
shift the shift lever to P. Failure to
do so may cause the vehicle to
move or the vehicle may acceler-
ate suddenly if t he accelerator
pedal is accidentally depressed.
■Avoiding damage to vehicle
parts
●Do not turn the steering wheel
fully in either direction and hold
it there for an extended period
of time.
Doing so may damage the
power steering motor.
●When driving over bumps in the
road, drive as slowly as possible
to avoid damaging the wheels,
underside of the vehicle, etc.

When the following unusual
operation is performed with the
accelerator pedal depressed,
the hybrid system output may be
restrained.
• When the shift lever is shifted to R
*.
• When the shift lever is shifted
from P or R to forward drive
shift position such as D
*.
When the system o perates, a mes-
sage appears on the multi-informa-
tion display. Read the message and
follow the instruction.
*: Depending on the situation, the shift position may not be
changed.
■Drive-Start Control (DSC)
When the TRAC is turned off
(  P.376), sudden start restraint
control also does not operate. If
your vehicle have trouble escaping
from the mud or fr esh snow due to
sudden start restraint operation,
deactivate TRAC ( P.376) so that
the vehicle may become able to
escape from the mud or fresh snow.
Also, sudden start restraint control
will not operate in the following con-
ditions:
●When the front-wheel drive control
switch is in “4H” or “4L” position.
(4WD models only)
●When AUTO LSD mode, the drive
start control does not operate. (if
equipped)
●When Multi-terrain Select is
selected. (if equipped)
NOTICE
■If you get a flat tire while driv-
ing
A flat or damaged tire may cause
the following situations. Hold the
steering wheel firmly and gradu-
ally depress the brake pedal to
slow down the vehicle.
●It may be difficult to control your
vehicle.
●The vehicle will make abnormal
sounds or vibrations.
●The vehicle will lean abnor-
mally.
Information on what to do in case
of a flat tire ( P.515)
■When encountering flooded
roads
Do not drive on a road that has
flooded after heavy rain, etc.
Doing so may cause the following
serious damage to the vehicle:
●Engine stalling
●Short in electrical components
●Engine damage caused by
water immersion
In the event that you drive on a
flooded road an d the vehicle
becomes flooded or stuck in mud
or sand, be sure to have your Toy-
ota dealer check the following:
●Brake function
●Changes in quantity and quality
of oil and fluid used for the
engine, transmission, transfer
(4WD vehicles), differential, etc.
●Lubricant condition for the pro-
peller shaft, bearings and sus-
pension joints (where possible),
and the function of all joints,

WARNING
■Overloading the vehicle
Do not overload the vehicle.
It may not only cause damage to
the tires, but also degrade steer-
ing and braking ability, resulting in
an accident.
Trailer towing
Your vehicle is designed pri-
marily as a passenger-and-
load-carrying vehicle. Tow-
ing a trailer can have an
adverse impact on handling,
performance, braking, dura-
bility, and fuel consumption.
For your safety and the
safety of others, you must
not overload your vehicle or
trailer. You must also
ensure that you are using
appropriate towing equip-
ment, that the towing equip-
ment has been installed
correctly and used prop-
erly, and that you employ
the requisite driving habits.
Vehicle-trailer stability and
braking performance are
affected by trailer stability,
brake performance and set-
ting, trailer brakes, the hitch
and hitch systems.
To tow a trailer safely, use
extreme care and drive the
vehicle in accordance with
your trailer’s characteris-
tics and operating condi-
tions.
Toyota warranties do not
apply to damage or mal-
function caused by towing a
trailer for commercial pur-
poses.

■Before towing
Check that the following conditions
are met:
●Ensure that your vehicle’s tires
are properly inflated. ( P.547)
●Trailer tires are inflated according
to the trailer manufacturer’s rec-
ommendation.
●All trailer lights work as required
by law.
●All lights work each time you con-
nect them.
●The trailer ball is set at the proper
height for the coupler on the
trailer.
●The trailer is level when it is
hitched. Do not dri ve if the trailer
is not level, and check for
improper tongue weight, overload-
ing, worn suspension, or other
possible causes.
●The trailer cargo is securely
loaded.
●The rear view mirrors conform to
all applicable federal, state/provin-
cial or local regu lations. If they do
not, install rear view mirrors
appropriate for towing purposes.
Contact your Toyota dealer for
further information about addi-
tional requirements such as a
towing kit, etc.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 brak ing 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.
●If the gross trailer weight is over
2000 lb. (900 kg), a sway con-
trol device with sufficient capac-
ity is required.
●If the gross trailer weight is over
5000 lb. (2200 kg), a weight dis-
tributing hitch with sufficient
capacity 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 spee d limit for your
trailer as set forth 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 hel p 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.

WARNING
●Do not make jerk y, 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 th e trailer hitch
assembly weight, gross vehicle
weight, gross axle weight and
trailer tongue weight capacities.
●Do not use the following sys-
tems when your vehicles is tow-
ing a trailer or a nother vehicle.
• PCS (Pre-Collision System)
• Dynamic radar cruise control with full-speed range
Except when the following condi-
tions are all met,
• When the other vehicle is a trailer properly attached and
connected to Toyota’s official
TBC ECU.
• When the vehicle is not being driven on a slippery surface
such as an icy road or a very
wet road.
●Do not use the following sys-
tems when your vehicles is tow-
ing a trailer or a nother vehicle.
• Cruise control (if equipped)
• LTA (Lane Tracing Assist)
If the vehicle detects that a trailer
is being towed, the lane centering
function of LTA is automatically
turned off.
●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 instability 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.
●Do not tow a trailer when the
temporary 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.
●If the gross tr ailer weight
exceeds unbraked TWR, trailer
brakes are required. Toyota rec-
ommends trailers with brakes
that conform to all applicable
federal and state/provincial reg-
ulations.
●Never tap into your vehicle’s
hydraulic system, as this will
lower the vehicle’s braking
effectiveness.
●Never tow a traile r without using
a safety chain securely attached
to both the trailer and the vehi-
cle. If damage occurs to the
coupling unit or hitch ball, there
is danger of the trailer wander-
ing into another lane.
