the gloves and touch the lock sen-
sor again.
●When the lock operation is per-
formed using the lock sensor, rec-
ognition signals will be shown up
to two consecutive times. After
this, no recogniti on signals will be
given.
●If the door handle becomes wet
while the electronic key is within
the effective ran ge, the door may
lock and unlock repeatedly. In that
case, follow the fo llowing correc-
tion procedures to wash the vehi-
cle:
• Place the electronic key in a loca- tion 6 ft. (2 m) or more away from
the vehicle. (Take care to ensure
that the key is not stolen.)
• Set the electronic key to battery- saving mode to disable the smart
key system. ( P.128)
●If the electronic key is inside the
vehicle and a door handle
becomes wet during a car wash, a
message may be shown on the
multi-informatio n display and a
buzzer will sound outside the vehi-
cle. To turn off the alarm, lock all
the doors.
●The lock sensor may not work
properly if it com es into contact
with ice, snow, mud, etc. Clean
the lock sensor and attempt to
operate it again, or use the lock
sensor on the lower part of the
door handle.
●A sudden approac h to the effec-
tive range or door handle may pre-
vent the doors from being
unlocked. In this case, return the
door handle to the original position
and check that the doors unlock
before pulling the door handle
again.
●If there is another electronic key in
the detection area, it may take
slightly longer to unlock the doors
after the door handle is gripped.

Sounding the horn

1704-1. Before driving
WARNING
●Moving the shift lever to N while
the vehicle is moving will disen-
gage the engine from the trans-
mission. Engine braking is not
available when N is selected.
●Be careful not to shift the shift
lever with the accelerator pedal
depressed.
Shifting the shift lever to a gear
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. Doing so can
damage the transmission and
may result in a loss of vehicle
control.
■If you hear a squealing or
scraping noise (brake pad
wear limit indicators)
Have the brake pads checked and
replaced by your Toyota dealer 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 race the engine.
If the vehicle is in any gear other
than P or N, the vehicle may
accelerate suddenly and unex-
pectedly, causing an accident.
●In order to prev ent accidents
due to the vehicle rolling away,
always keep depressing the
brake pedal while the engine is
running, and apply the parking
brake as necessary.
●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 cause 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 se at is adjusted,
causing a fire.

Driving
WARNING
●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 as a lens, caus-
ing a fire.
●Always apply the parking brake,
shift the shift lever to P, stop the
engine and lock the vehicle.
Do not leave the vehicle unat-
tended while the engine is run-
ning.
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 engine is running or
immediately after turning the
engine off.
Doing so may cause burns.
■When taking a nap in the
vehicle
Always turn the e ngine off. Other-
wise, if you accidentally move the
shift lever or dep ress the acceler-
ator pedal, this could cause an
accident or fire due to engine
overheating. Additionally, if the
vehicle is parked in a poorly venti-
lated area, exhaust gases may
collect and enter the vehicle, lead-
ing to death or a serious health
hazard.
■When braking
●When the brakes are 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. A lso, the parking
brake may not securely hold the
vehicle.
●If the brake booster device does
not operate, do not follow other
vehicles closely and avoid hills
or sharp turns t hat require brak-
ing.
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.
●Do not pump the brake pedal if
the engine stalls.
Each push on the brake pedal
uses up the reserve for the
power-assisted brakes.
●The brake system consists of 2
individual hydraulic systems; 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
(AWD models)
Do not spin the wheels exces-
sively when any of the tires 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.

1744-1. Before driving
Cargo capacity depends on the
total weight of the occupants.
(Cargo capacity) = (Total load
capacity) - (Total weight of occu-
pants)
Steps for Determining Correct
Load Limit 
(1) Locate the statement “The
combined weight of occupants
and cargo should never exceed
XXX kg or XXX lbs.” on your
vehicle’s placard.
(2) Determine the combined
weight of the driver and passen-
gers that will be riding in your
vehicle.
(3) Subtract the combined
weight of the driver and passen-
gers from XXX kg or XXX lbs.
(4) The resulting figure equals the available amount of cargo
and luggage load capacity.
For example, if the “XXX”
amount equals 1400 lbs. and
there will be five 150 lb passen-
gers in your vehicle, the amount
of available cargo and luggage
load capacity is 650 lbs. (1400 -
750 (5 
150) = 650 lbs.)
(5) Determine the combined
weight of luggage and cargo
being loaded on the vehicle.
That weight may not safely
exceed the available cargo and
luggage load capacity calcu-
lated in Step 4.
(6) If your vehicle will be towing
a trailer, load from your trailer
will be transferred to your vehi-
cle. Consult this manual to
determine how this reduces the
available cargo and luggage
load capacity of your vehicle.
( P.176)
WARNING
●Secure all items in the occupant
compartment.
●When you fold down the rear
seats, long items should not be
placed directly behind the front
seats.
●Never allow anyone to ride in
the luggage compartment. It is
not designed for passengers.
They should ride in their seats
with their seat belts properly
fastened. Otherwise, they are
much more likely to suffer death
or serious bodily injury, in the
event of sudden braking, sud-
den swerving or an accident.
Capacity and distribution
WARNING
■Capacity and distribution
●Do not exceed the maximum
axle weight rating or the total
vehicle weight rating.
●Even if the total load of occu-
pant’ weight and the cargo load
is less than the total load capac-
ity, do not apply the load
unevenly. Improper loading may
cause deterioration of steering
or braking control which may
cause death or serious injury.

Cargo capacity
Total load capacity (vehicle
capacity weight) (P.660)
When 2 people with the com-
bined weight of A lb. (kg) are rid-
ing in your vehicle, which has a
total load capacity (vehicle
capacity weight) of B lb. (kg),
the available amount of cargo
and luggage load capacity will
be C lb. (kg) as follows:
B
*2 lb. (kg) - A*1 lb. (kg) = C*3 lb.
(kg)
*1: A = Weight of people
*2: B = Total load capacity
*3: C = Available cargo and luggage load
In this condition, if 3 more passen-
gers with the combined weight of D
lb. (kg) get on, the available cargo
and luggage load will be reduced E
lb. (kg) as follows:
C lb. (kg) - D*4 lb. (kg) = E*5 lb.
(kg)
*4: D = Additional weight of people
*5: E = Available cargo and luggage load
As shown in the example above,
if the number of occupants
increases, the cargo and lug-
gage load will be reduced by an
amount that equals the
increased weight due to the
additional occupants. In other
words, if an increase in the num-
ber of occupants causes an
excess of the total load capacity
(combined weight of occupants
plus cargo and luggage load),
you must reduce the cargo and
luggage on your vehicle.

■When loading cargo on the
roof luggage carrier (if
equipped)
Observe the following precau-
tions:
●Place the cargo so that its
weight is distributed evenly
between the front and rear
axles.
●If loading long or wide cargo,
never exceed the vehicle overall
length or width. ( P.660)
●Before driving, m ake sure the
cargo is securely fastened on
the roof luggage carrier.
●Loading cargo on the roof lug-
gage carrier will make the cen-
ter of gravity of the vehicle
higher. Avoid high speeds, sud-
den starts, sharp turns, sudden
braking or abrupt maneuvers,
otherwise it may result in loss of
control or vehicle rollover due to
failure to operate this vehicle
correctly and result in death or
serious injury.

1784-1. Before driving
■Before towing
Check that the following conditions
are met:
●Ensure that your vehicle’s tires
are properly inflated. ( P.667)
●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 drive if the trailer is not
level, and check for improper
tongue weight, overloading, 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.
Toyota warranties do not
apply to damage or mal-
function caused by towing a
trailer for commercial pur-
poses.
Contact your Toyota dealer for
further information about addi-
tional requirements such as a
towing kit, etc.WARNING
■Trailer towing precautions
To tow a trailer 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. Yo ur 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 with towing package: 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 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 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.

Driving
■GCWR (Gross Combination
Weight Rating)
The maximum allowable gross
combination weight. The gross
combination weight is the sum
of the total vehicle weight
(including the occupants, cargo
and any optional equipment
installed on the vehicle) and the
weight of the trailer being towed
(including the cargo in the
trailer).
WARNING
●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 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 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
compact spare tire is installed
on your vehicle.
■When towing a trailer
Toyota recommends trailers with
brakes that confor m to any appli-
cable federal and state/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.
