WARNING
Observe the following precautions.
Failure to do so may result in death or serious injury.
■If you hear a squealing or scrapi ng noise (brake pad wear limit indica-
tors)
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 unexpectedly, causing an accident.
● In order to prevent 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 accidents caused
by the vehicle rolling 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 combusti\
ble
material is nearby.

WARNING
Observe the following precautions.
Failure to do so may result in death or serious injury.
■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. Also, the
parking brake may not securely hold the vehicle.
● If the power brake assist function does not operate, do not follow other\
vehicles closely and avoid hills or sharp turns that require braking.
In this case, braking is still possible, but the brake pedal should be
depressed more firmly than usual. Also, the braking 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 excessively when any of the tires is up in the air, or
the vehicle is stuck in sand, mud, etc. This may damage the driveline com-
ponents or propel the vehicle forward or backward, 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 driving torque.
● Do not use the accelerator pedal or depress the accelerator and brake
pedals at the same time to hold the vehicle on a hill.

WARNING
■Things that must not be carried in the luggage compartment
The following things may cause a fire if loaded in the luggage compart-
ment:
●Receptacles containing gasoline
●Aerosol cans
■Storage precautions
Observe the following precautions.
Failure to do so may prevent the pedals from being depressed properly,
may block the driver’s vision, or may result in items hitting the driver or
passengers, possibly causing an accident.
●Stow cargo and luggage in the luggage compartment whenever possi-
ble.
●Do not stack cargo and luggage in the luggage compartment higher
than the seatbacks.
●Do not place cargo or luggage in or on the following locations.
• At the feet of the driver
• On the front passenger or rear seats (when stacking items)
• On the instrument panel
• On the dashboard
●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.

WARNING
■Capacity and distribution
●Do not exceed the maximum axle weight rating or the total vehicle
weight rating.
●Even if the total load of occupant’s weight and the cargo load is less
than the total load capacity, do not apply the load unevenly. Improper
loading may cause deterioration of steering or braking control which
may cause death or serious injury.
■Roof luggage carrier precautions (vehicles with roof rails)
To use the roof rails as a roof luggage carrier, you must fit the roof rails
with two or more genu ine Toyota cross rails or their equivalent.
When you load cargo on the roof luggage carrier, observe the following:
●Loading cargo on the roof luggage carrier will make the center of the
vehicle gravity higher. Avoid high speeds, sudden starts, sharp turns,
sudden braking or abrupt maneuvers, otherwise it may result in loss of
control or vehicle rollover due to failu re to operate this vehicle correctly
and result in death or serious injury.
●If driving for a long distance, on r ough roads, or at high speeds, stop
the vehicle now and then during the trip to make sure the cargo
remains in its place.
●Do not exceed 165 lb. (75 kg) cargo weight on the roof luggage carrier.
●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. 650)
●Before driving, make sure the cargo is
securely fastened on the roof luggage
carrier.

■Matching trailer ball height to trailer coupler height
■ Before towing
Check that the following conditions are met:
●Ensure that your vehicle’s tires are properly inflated. ( →P. 660)
● Trailer tires are inflated according to the trailer manufacturer’s recommen-
dation.
● All trailer lights work as required by law.
● All lights work each time you connect 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/provincial or
local regulations. If they do not, install rear view mirrors appropriate for tow-
ing purposes.
No matter which class of tow hitch
applies, for a more safe trailer hookup,
the trailer ball setup must be the proper
height for the coupler on the trailer.

WARNING
●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 downhill
grades. Avoid holding the brake pedal down too long or applying the
brakes too frequently. This could cause the brakes to overheat and result
in reduced braking efficiency.
● Vehicles with a compact spare tire: Do not tow a trailer when the compact
spare tire is installed on your vehicle.
■ Hitch
Trailer hitch assemblies have different weight capacities established by the
hitch manufacturer. Even though the vehicle may be physically capable of
towing a higher weight, the operator must determine the maximum weight
rating of the particular hitch assembly and never exceed the maximum
weight rating specified for the trailer-hitch. Exceeding the maximum weight
rating set by the trailer-hitch manufacturer can cause an accident resulting
in death or serious personal injuries.
■ When towing a trailer
Toyota recommends trailers with brakes that conform to any applicable fed-
eral and state/provincial regulations.
● If the gross trailer weight exceeds unbraked TWR, trailer brakes are
required. Toyota recommends trailers with brakes that conform to all appli-
cable federal and state/provincial regulations.
● Never tap into your vehicle’s hydraulic system, as this will lower the vehi-
cle’s braking effectiveness.
● Never tow a trailer without using a safety chain securely attached to both
the trailer and the vehicle. If damage occurs to the coupling unit or hitch
ball, there is danger of the trailer wandering into another lane.
NOTICE
■When installing a trailer hitch
Use only the position recommended by your Toyota dealer. Do not install
the trailer hitch on the bumper; this may cause body damage.
■ Do not directly splice trailer lights
Do not directly splice trailer lights. Directly splicing trailer lights may damage
your vehicle’s electrical system and cause a malfunction.
