■Before towing
●Ensure that your vehicle’s tires are properly inflated. (→P. 3 3 4 )
●Trailer tires should be inflated according to the trailer manufacturer's recom-
mendation.
●All trailer lights 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, install 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
power train components (engine, transmission, differential, wheel bearings, 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 “Warranty and Services Guide/Owner's Manual Sup-
plement/ Scheduled Maintenance”.)
●Retighten the fixing bolts of the towing ball and bracket after approximately
600 miles (1000 km) of trailer towing.
CAUTION
■To avoid accident or injury
●The total trailer weight (trailer weight plus the weight of cargo) must not exceed
1000 lb. (450 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
r e a r.

Be sure to observe the following precautions. Failure to do so could cause loss of
vehicle control and result in death or serious injury.
●Stop your vehicle in a safe place as soon as possible. Adjust the tire inflation pres-
sure immediately.
●If the tire pressure warning light comes on even after tire inflation pressure adjust-
