SEQUOIA_OM_USA_OM0C047U
WARNING
Observe the following precautions.
Failure to do so may result in death or serious injury.
■When taking a nap in the vehicle
Always turn the engine off. Otherwise, if you accidentally move the shift
lever or depress the accelerator pedal, this could cause an acc ident or fire
due to engine overheating. Additionally, if the vehicle is parked in a poorly
ventilated area, exhaust gases may collect and enter the vehicl e, leading 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. Also, the
parking brake may not securely hold the vehicle.
● If the brake booster device does not operate, do not follow oth er vehicles
closely and avoid hills or shar p 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 dist ance will
increase.
If this happens, do not continue to drive the vehicle. Have you r brakes
fixed immediately.
■ If the vehicle becomes stuck (4WD 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.

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 pr operly,
may block the driver’s vision, or may result in items hitting t he driver or
passengers, possibly causing an accident.
●Stow cargo and luggage in the luggage compartment whenever poss i-
ble.
●Do not stack cargo and luggage in the luggage compartment highe r
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 rea r 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 pla ced
directly behind the front seats.
●Never allow anyone to ride in the luggage compartment. It is no t
designed for passengers. They should ride in their seats with their seat
belts properly fastened. Otherwise, they are much more likely t o suffer
death or serious bodily injury, in the event of sudden braking, sudden
swerving or an accident.

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. I mproper
loading may cause deterioration of steering or braking control which
may cause death or serious injury.
■When loading cargo on the roof luggage carrier
Observe the following precautions:
●Place the cargo so that its weight is distributed evenly betwee n the
front and rear axles.
●If loading long or wide cargo, never exceed the vehicle overall length
or width. ( P. 522)
●Before driving, make sure the cargo is securely fastened on the roof
luggage carrier.
●Loading cargo on the roof luggage carrier will make the center of grav-
ity of the vehicle 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 failure to operate this vehi cle correctly
and result in death or serious injury.
●If driving for a long distance, on rough roads, or at high spee ds, stop
the vehicle now and then during the trip to make sure the cross rails
are fixed securely and that the cargo remains in its place.
●Do not exceed 150 lb. (68 kg) cargo weight on the roof luggage carrier.

Before towing
Check that the following conditions are met:
●Ensure that your vehicle’s tires are properly inflated. ( P. 531)
● Trailer tires are inflated according to the trailer manufacture r’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 imprope r 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 ap propriate for tow-
ing purposes.
● Depress “TOW/HAUL” button (if equipped)
■ AVS (adaptive variable suspension system) (if equipped)
The suspension can be switched for improvement in drivability. (P. 316)
■ Break-in schedule
If your vehicle is new or equipped with any new power train com ponents
(such as an engine, transmission, differential or wheel bearing ), Toyota rec-
ommends that you do not tow a trailer until the vehicle has bee n driven for
over 500 miles (800 km).
After the vehicle has been driven for over 500 miles (800 km), you can start
towing. However, for the next 500 miles (800 km), drive the veh icle at a speed
of less than 50 mph (80 km/h) when towing a trailer, and avoid full throttle
acceleration.
■ Maintenance
●If you tow a trailer, your vehicle will require more frequent m aintenance due
to the additional load. (See “Scheduled Maintenance Guide” or “ Owner’s
Manual Supplement”.)
● Retighten the fixing bolts of the towing ball and bracket after approximately
600 miles (1000 km) of trailer towing.

WARNING
■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 t o all appli-
cable federal and state/provincial regulations.
● Never tap into your vehicle’s hydraulic system, as this will lo wer the vehi-
cle’s braking effectiveness.
● Never tow a trailer without using a safety chain securely attac hed to both
the trailer and the vehicle. If damage occurs to the coupling u nit or hitch
ball, there is danger of the trailer wandering into another lan e.
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 traile r lights may damage
your vehicle’s electrical system and cause a malfunction.
