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. 638)
●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. 646)
● 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
■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.

2284-2. Driving procedures

After turning the power switch off and opening and closing the doors, the
steering wheel will be locked due to the steering lock function. Operating the
power switch again automatically cancels the steering lock.
■ When the steering lock cannot be released
■ Steering lock motor o verheating prevention
To prevent the steering lock motor from overheating, operation of the motor
may be suspended if the hybrid system is turned on and off repeatedly in a
short period of time. In this case, refrain from operating the hybrid system.
After about 10 seconds, the steering lock motor will resume functioning.
■ When “Check SMART Key System” will be displayed on the multi-infor-
mation display
The system may be malfunctioning. Have the vehicle inspected by your
Toyota dealer immediately.

Driving
HIGHLANDER_HV_U (OM48F12U)
WARNING
■When refueling the vehicle
Observe the following precautions while refueling the vehicle. Failure to do
so may result in death or serious injury.
● After exiting the vehicle and before opening the fuel door, touch an
unpainted metal surface to discharge any static electricity. It is important to
discharge static electricity before refueling because sparks resulting from
static electricity can cause fuel vapors to ignite while refueling.
● Always hold the grips on the fuel tank cap and turn it slowly to remove it.
A whooshing sound may be heard when the fuel tank cap is loosened.
Wait until the sound cannot be heard before fully removing the cap. In hot
weather, pressurized fuel may spray out the filler neck and cause injury.
● Do not allow anyone that has not discharged static electricity from their
body to come close to an open fuel tank.
● Do not inhale vaporized fuel.
Fuel contains substances that are harmful if inhaled.
● Do not smoke while refueling the vehicle.
Doing so may cause the fuel to ignite and cause a fire.
● Do not return to the vehicle or touch any person or object that is statically
charged.
This may cause static electricity to build up, resulting in a possible ignition
hazard.
■ When refueling
Observe the following precautions to prevent fuel overflowing from the fuel
tank:
● Securely insert the fuel nozzle into the fuel filler neck.
● Stop filling the tank after the fuel nozzle automatically clicks off.
● Do not top off the fuel tank.
NOTICE
■Refueling
● Finish refueling within 30 minutes. If more than 30 minutes passes, the
internal valve closes. In this condition, fuel may spill out if you continue to
refuel the vehicle. About 5 minutes after the valve is closed, a message
“Close Fuel Lid” will appear on the multi-information display. To refuel the
vehicle again, tighten the fuel tank cap and close the fuel filler door, and
then press the opener switch again.
● Do not spill fuel during refueling.
Doing so may damage the vehicle, such as causing the emission control
system to operate abnormally or damaging fuel system components or the
vehicle’s painted surface.

• When driving up and down consecutive steep inclines, such as hills, dips in the road, etc.
• When driving on roads with sharp bends, consecutive curves, or uneven surfaces
