When driving
As shown in the above example, if the number of occupants increases,
the cargo and luggage load equaling the combined weight of the occu-
pants who got on later, by an amount. In other w
ords, if an increase in the
number of occupants causes an excess of the total load capacity (com -
bined weight of occupants plus car go and luggage load), y
ou must
reduce the cargo and luggage on your vehicle. ( P.148 )
CAUTION
■Storage precautions
●Do not place anything on the packag e tray behind the rear seatback. 
Such items may be thrown about and possib ly injur
e people in the vehicle during
sudden braking or in an accident.
●Do not drive with objects on top of the instrument panel. 
They may interfere with the driver’s field of view or move during sharp accelera -
tion or turning, thus impairing the driver ’
s control of the vehicle. In an accident
they may injure the vehicle occupants.
●Secure all items in the occupant compartment, as they may shift and injure some -
one during an accident or sudden braking.
■Weight of the load
●Improper loading may cause deterioratio n of steering or braking control result-
ing in an accident which may cause death or serious injury.
●Do not exceed the maximum axle weight ra ting 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.

■Before towing
●Ensure that your vehicle’s tires are properly inflated. (P.283 )
●Trailer tires should be inflated according to the trailer manufacturer’s recom -
mendation.
●All trailer lights must work to be legal.
●Confirm all lights work each time you connect them.
●Check that your vehicle remains level when a loaded or unloaded trailer is
hitched. Do not drive if the vehicle is not level, and check for improper tongue
load, overloading, worn suspension, or other possible causes.
●Make sure the trailer cargo is securely loaded.
●Check that your rear view mirrors conform to any federal, state/provincial or
local regulations. If they do not, instal l rear view mirrors appropriate for towing
purposes.
■Break-in schedule
Lexus recommends that you do not use a new vehicle or a vehicle with any new
p

ower train components (engine, transmissi on, differential, wheel bearing, etc.) to
tow a trailer for the first 500 miles (800 km) of driving.
■Maintenance
●If you tow a trailer, your vehicle will require more frequent maintenance due to
the additional load. (see “Owner’s Manual Supplement/ Scheduled Mainte -
nance”)
●Retighten the fixing bolts of the towing ball and bracket after approximately
600 miles (1000 km) of trailer towing.

When driving
CAUTION
■To avoid accident or injury
●The total trailer weight (trailer weight plus the weight of cargo) must not exceed
2000 lb. (907 kg).
●Do not exceed the trailer hitch assembly weight, gross vehicle weight, gross axle
weight and trailer tongue load capacities.
●Never load more weight in the back than in the front of the trailer. About 60% of
the load should be in the front half of the trailer, and the remaining 40% in the
rear.
■Hitches
Trailer hitch assemblies have different weight capacities established by the hitch
ma

nufacturer. Even though the vehicle may be physically capable of towing a
higher weight, the operator must never exceed the maximum weight rating speci -
fied for the trailer hitch.
• If you wish to install a trailer hitch, your Lexus dealer should be consulted.
• 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 r
emoving the hitch, seal any mounting holes in the vehicle body to prevent
entry of any substances into the vehicle.
■When towing a trailer
●If the total trailer weight exceeds 1000 lb . (450 kg), trailer brakes are required.
●Never tap into your vehicle's hydraulic system, as this will lower the vehicle'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.
