CAUTION
■Storage precautions
Observe the following precautions.
Failure to do so may result in death or serious injury.
●Stow cargo and luggage in the lugga ge compartment whenever possible.
●Do not stack cargo and luggage in the luggage compartment higher than the
seatbacks. 
Such items may be thrown about and possib ly injure people in the vehicle in the
event of a sudden braking, sudd en swerving or an accident.
●Do not place cargo or luggage in or on the following locations as the item may
get under the brake or accelerator pedal and prevent the pedals from being
depressed properly, block the driver’s vision, or hit the driver or passengers,
causing an accident:
• At the feet of the driver
• On the front passenger or rear seats (when stacking items)
• On the luggage cover
• On the instrument panel
•On the dashboard
●Secure all items in the occupant compartment, as they may shift and injure some-
one in the event of a sudden braking, sudden swerving or an accident.
●When you fold down the rear seats, lo ng items should not be place 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 seat s 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 or an accident.
■Roof luggage carrier precautions
To use the roof rails as a roof luggage carrier, you must fit the roof rails with two or
more genuine Lexus cross rails or their equivalent. 
Follow the manufacturer’s instructions and precautions when installing the cross
rails or their equivalent.

CAUTION
■To avoid accident or injury
●Do not use cruise control when you are towing.
●Slow down and downshift before descending steep or long downhill grades. Do
not make sudden downshifts.
●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.
■Hitches
●If you wish to install a trailer hitch, contact your Lexus dealer.
●Use only a hitch that conforms to the total trailer weight requirement.
●Follow the directions supplied by the hitch manufacturer.
●Lubricate the hitch ball with a light coat of grease.
●Remove the trailer hitch whenever you are not towing a trailer. After removing
the hitch, seal any mounting hole in the vehicle body to prevent entry of any sub-
stances into the vehicle.
■When towing a trailer
●If the total trailer weight exceeds 1000 lb . (453 kg), trailer brakes are required.
●Never tap into your vehicle’s hydraulic system, as this will lower the vehicle’s brak-
ing 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
a risk of the trailer wandering into another lane.
