Owners Manual_USA_M0C052_enbecause visibility will be reduced,
the windows may become fogged-
up, and the
road will be slippery.
●Drive carefully whe n it starts to
rain, because the road surface will
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.
■Engine speed while driving
In the following conditions, the
engine speed may become high
while driving.
This is due to automatic up-shifting
control or down-shifting implementa-
tion to meet driving conditions. It
does not indicate sudden accelera-
tion.
●The vehicle is judged to be driving
uphill or downhill
●When the accelerator pedal is
released
●When the brake pedal is
depressed while “TOW HAUL”
mode or “TOW+” mode is selected
■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 messag e is displayed
on the multi-information display
while the system is operating.
■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 1000 miles (1600 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 for extended periods.
■Operating your v ehicle in a for-
eign country
Comply with the relevant vehicle
registration laws and confirm the
availability of the correct fuel.
(  P.542)
WARNING
Observe the following precau-
tions.
Failure to do so may result in
death or serious injury.
■When starting the vehicle
Always keep your foot on the
brake pedal while stopped with
the “READY” indica tor is illumi-
nated. This prevents the vehicle
from creeping.
■When driving the vehicle
●Do not drive if you are unfamil-
iar with the location of the brake
and accelerator pedals to avoid
depressing the wrong pedal.
• Accidentally depressing the accelerator pedal instead of the
brake pedal will result in sudden
acceleration that may lead to an
accident.
• When backing up, you may twist your body around, leading to dif-
ficulty in operating the pedals.
Make sure to operate the pedals
properly.
• Make sure to keep a correct driving posture even when mov-
ing the vehicle only slightly. This
allows you to depress the brake
and accelerator pedals properly.

1744-1. Before driving
Owners Manual_USA_M0C052_en
WARNING
■When driving on slippery
road surfaces
●Sudden braking, acceleration
and steering may cause tire
slippage and reduce your ability
to control the vehicle.
●Sudden acceleration, engine
braking due to shifting, or
changes in engine speed could
cause the vehicle to skid.
●After driving through a puddle,
lightly depress the brake pedal
to make sure that the brakes
are functioning properly. Wet
brake pads may prevent the
brakes from functioning prop-
erly. If the brakes on only one
side are wet and not functioning
properly, steering control may
be affected.
■When shifting the shift lever
●Do not let the vehicle roll back-
ward while a forward driving
position is selected, or roll for-
ward while the shift lever is in R.
Doing so may result in an acci-
dent or damage to the vehicle.
●Do not shift the shift lever to P
while the vehicle is moving.
Doing so can damage the trans-
mission and may result in a loss
of vehicle control.
●Do not shift the shift lever to R
while the vehicle is moving for-
ward.
Doing so can damage the trans-
mission and may result in a loss
of vehicle control.
●Do not shift the shift lever to a
driving position while the vehicle
is moving backward.
Doing so can damage the trans-
mission and may result in a loss
of vehicle control.
●Moving the shift lever to N while
the vehicle is moving will disen-
gage the hybrid system. Engine
braking is not available with the
hybrid system disengaged.
●Be careful not to shift the shift
lever with the accelerator pedal
depressed. Shifting the shift
lever to any positions other than
P or N may lead to unexpected
rapid acceleration of the vehicle
that may cause an accident and
result in death or serious injury.
■If you hear a squealing or
scraping noise (brake pad
wear indicators)
Have the brake pads checked and
replaced by your Toyota dealer, or
any reliable repairer as soon as
possible.
Rotor damage may result if the
pads are not replaced when
needed.
It is dangerous to drive the vehicle
when the wear limits of the brake
pads and/or those of the brake
discs are exceeded.
■When the vehicle is stopped
●Do not depress the accelerator
pedal unnecessarily.
If the shift lever is any position
other than P or N, the vehicle
may accelerate suddenly and
unexpectedly, causing an acci-
dent.
●In order to prevent accidents
due to the vehic le rolling away,
always keep depressing the
brake pedal while stopped with
the “READY” indicator is illumi-
nated, and apply the parking
brake as necessary.

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)

■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.
