CAUTION
■Storage precautions
Observe the following precautions.
Failure to do so may result in death or serious injury.
●Stow cargo and luggage in the luggage compartment whenever possible.
●Do not stack cargo and luggage in the luggage compartment higher than the
seatbacks.
Such items may be thrown about and possibly injure people in the vehicle in the
event of a sudden braking, sudden 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, long 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 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 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.

Trailer towing
Your vehicle is designed primarily as a passenger-and-load-carrying vehi-
cle. Towing a trailer can have an adverse impact on handling, performance,
braking, durability, and fuel consumption. For your safety and the safety of
others, you must not overload your vehicle or trailer. You must also ensure
that you are using appropriate towing equipment, that the towing equip-
ment has been installed correctly and used properly, and that you employ
the requisite driving habits.
Vehicle-trailer stability and braking performance are affected by trailer
stability, brake performance and setting, trailer brakes, the hitch and hitch
systems (if equipped).
To tow a trailer safely, use extreme care and drive the vehicle in accor-
dance with your trailer’s characte ristics and operating conditions.
Lexus warranties do not apply to dama ge or malfunction caused by towing
a trailer for commercial purposes.
Contact your Lexus dealer for further information about additional
requirements such as towing kits, etc.

Towing related terms■ 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).
■ GVWR (Gross Vehicle Weight Rating)
The maximum allowable gross
vehicle weight. The gross vehicle
weight is the total weight of the
vehicle. When towing a trailer, it is
the sum of the vehicle weight
(including the occupants, cargo
and any optional equipment
installed on the vehicle) and the
tongue weight.

TWR (Trailer Weight Rating)
The maximum allowable gross
trailer weight. The gross trailer
weight is the sum of the trailer
weight and the weight of the cargo
in the trailer.
TWR is calculated assuming base
vehicle with one driver, one front
passenger, towing package (if
available), hitch and hitch systems
(if required).
Additional optional equipment,
passengers and cargo in the vehi-
cle will reduce the trailer weight
rating so as not to exceed GCWR,
GVWR and GAWR.
If the gross trailer weight exceeds
3000 lb. (1360 kg), it is recom-
mended to use a trailer with 2 or
more axles.
(With brakes)

Trailer Tongue Weight● A recommended tongue weight varies in accordance with the types of
trailers or towing as described below.
● To ensure the recommended values shown below, the trailer must be
loaded by referring to the following instructions.
• Tongue Weight
The gross trailer weight should be distributed so that the tongue
weight is 9 % to 11 %. (Tongue weight/Gross trailer weight × 100 =
9% to 11%)
Gross trailer weight
Tongue weight
If using a weight distributing hitch when towing, return the front axle
to the same weight as before the trailer connection.
If front axle weight cannot be measured directly, measure the front
fender height above the front axle before connection. Adjust weight
distributing hitch torque until front fender is returned to the same
height as before connection.
The gross trailer weight, gross axle weight and tongue weight can be
measured with platform scales found at a highway weighing station,
building supply company, trucking company, junk yard, etc.

mends the use of Lexus hitch/bracket for your vehicle. For details, con-
tact your Lexus dealer.
● If you wish to install a trailer hitch, contact your Lexus dealer.
● Use only a hitch that conforms to the gross trailer weight requirement
of your vehicle.
● Follow the directions supplied by the hitch manufacturer.
● Lubricate the hitch ball with a light coating 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 pre-
