Wait until vehicle height is stabilized.
STEP 7
Make sure the hitch is disconnected. If the hitch does not disconnect, raise the hitch
higher and repeat steps 2 through 7.
Before towing
■
Check that the following conditions are met:
The vehicle's tires are properly inflated. (→P. 505)
●
Trailer tires are inflated according to the trailer manufacturer's recommendation.
●
All trailer lights work.
●
All lights work each time you connect them.
●
The 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.
The trailer cargo is securely loaded.
●
The rear view mirrors conform to all applicable federal, state/provincial or local
●
regulations. If they do not, install rear view mirrors appropriate for towing pur-
poses.
Break-in schedule
■
If your vehicle is new or equipped with any new power train components (such as
an engine, hybrid transmission, and wheel bearings), Lexus 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 "Warranty and Services Guide", "Owner's Manual Sup-
plement" or "Scheduled Maintenance".)
Retighten the fixing bolts of the towing ball and bracket after approximately 600
●
miles (1000 km) of trailer towing.
