CAUTION
■When the sensor may not be correctly detecting the vehicle ahead
Apply the brakes as necessary in any of the following situations.
●When water or snow thrown up by the surrounding vehicles hinders the function-
ing of the sensor
●When your vehicle is pointing upwards (caused by a heavy load in the luggage
compartment etc.)
●Vehicles that cut in suddenly
●Vehicles with small rear ends (trailers with no load on board etc.)
●Motorcycles traveling in the same lane
■Handling the radar sensor
Observe the following to ensure the pre-collision system can function effectively:
●Keep the sensor and front grille cover clean at all times. 
Clean the sensor and front grille cover with a soft cloth so you do not mark or
damage them.
●Do not subject the sensor or surrounding area to a strong impact. 
If the sensor moves even slightly off position, the system may malfunction. If the
sensor or surrounding area is subject to a strong impact, always have the area
inspected and adjusted by your Lexus dealer.

Capacity and distributionCargo capacity depends on the to tal weight of the occupants.
(Cargo capacity) = (Total load capa city) — (Total weight of occupants)
Steps for Determining Correct Load Limit —
(1) Locate the statement “The combined weight of occupants and cargo should never exceed XXX kg or XXX lbs.” on your vehicle’s
placard.
(2) Determine the combined weight of the driver and passengers that
will be riding in your vehicle.
(3) Subtract the combined weight of the driver and passengers from
XXX kg or XXX lbs.
(4) The resulting figure equals the av ailable amount of cargo and lug-
gage load capacity.
For example, if the “XXX” amount equals 1400 lbs. and there will be
five 150 lb passengers in your vehicl e, the amount of available cargo
and luggage load capacity is 650 lbs. (1400 - 750 (5 150) = 650
lbs.)
(5) Determine the combined weight of luggage and cargo being
loaded on the vehicle. That weight may not safely exceed the avail-
able cargo and luggage load capacity calculated in Step 4.
(6) If your vehicle will be towing a trailer, load from your trailer will be transferred to your vehicle. Consu lt this manual to determine how
this reduces the available cargo and luggage load capacity of your
vehicle. ( P. 359)

Trailer towing
Your vehicle is designed primarily as a passenger-and-load carrying vehi-
cle. Towing a trailer will have an adverse effect on handling, performance,
braking, durability, and fuel consumptio n. For your safety and the safety of
others, do not overload the vehicle or trailer.
To tow a trailer safely, use extreme care and drive the vehicle in accor-
dance with the trailer’s characteristics and operating conditions. The vehi-
cle stability and braking performance are affected by trailer stability, brake
setting and performance, and the hitch.
Lexus warranties do not apply to damage or malfunction caused by towing
a trailer for commercial purposes.
Contact your Lexus dealer for furt her information about additional
requirements such as a towing kits, etc.
■ Weight limits
Confirm that the total trailer weight , gross vehicle weight, gross axle
weight and trailer tongue lo ad are all within the limits.

■Trailer tongue load
●A recommended tongue load varies in accordance with the types
of trailers or towing as described below.
● In order to ensure the recommen ded values shown below, the
trailer must be loaded by referring to the following instructions.
The trailer cargo load should be distributed so that the tongue
load is 9 to 11 % of the total trailer weight, not exceeding 650 lb.
(294 kg). (Tongue load/Total trailer weight  100 = 9 to 11 %)
If the gross trailer weight is ov er 2000 lbs. (900 kg), it is neces-
sary to use a sway control de vice with sufficient capacity.
If the gross trailer weight is ov er 5000 lbs. (2268 kg), it is neces-
sary to use a weight distributing hitch with sufficient capacity.
If using a weight distributing hitc h when towing, keep your vehicle
level with the ground.
The total trailer weight and tongue load can be measured with
platform scales found at a highway weighing stations, building
supply companies, trucking co mpanies, junk yards, etc.

trailer, it is the sum of the vehicle weight
(including the occupants, cargo and any
optional equipment installed on the vehi-
cle) and the tongue load.

Rating)The maximum allowable gross axle weight. 
The gross axle weight is the load placed on
each axle (front and rear).
GCWR (Gross Combination
Weight Rating)
The maximum allowable gross combina-
tion weight. The gross combination weight
is the sum of the total vehicle weight
(including the occupants, cargo and any

Trailer hitch assemblies have differen t weight capacities established by
the hitch manufacturer. Ev en though the vehicle may be rated for towing
a higher weight, the operator must never exceed the maximum weight
rating specified for the trailer hitch.
Towing related termMeaning
Towing capacity
The maximum allowable gross trailer
weight. Towing capacity is calculated con-
sidering the base vehicle with necessary
vehicle equipment and occupants. Addi-
tional optional equipment, passengers and
cargo in the vehicle will reduce the towing
