■
Break-in schedule
If your vehicle is new or equipped with any new power train components
(such as an engine, transmission, differential and wheel bearing), Toyota
recommends that you do not tow a trailer until it has been driven for over
500 miles (800 km).
However, avoid full throttle acceleration.
■
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.
