When driving
■
Before towing
●Ensure that your vehicle’s tires are properly inflated. ( P. 392)
● Trailer tires should be inflated according to the trailer manufacturer's rec-
ommendation.
● All trailer lights must work in order 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 c onform to any federal, state/provincial
or local regulations. If they do not, inst all rear view mirrors appropriate for
towing purposes.
■ Break-in schedule
Toyota recommends that you do not use a new vehicle or a vehicle with any
new power train components (engine, transmission, differential, wheel bear-
ings, 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 “Scheduled Maintenance Guide” or
“Owner's Manual Supplement”.)
● Retighten the fixing bolts of the towing ball and bracket after approxi-
mately 600 miles (1000 km) of trailer towing.
