Before towing
Check that the followin g conditions are met:●
Ensure that your vehicle’s tires are properly inflated. ( → P. 565)●
Trailer tires are inflated a ccording to the trailer manufacturer’s recommendation.●
All trailer lights work as required by law. ●
All lights work each time you connect them.●
The trailer ball is set at the proper height for the coupler on the trailer. ●
The trailer is level when it is hitched.
Do not drive if the trailer is not level, and check for improper to ngue weight, overload-
ing, 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 regula-
tions. If they do not, install rear view mirrors appropriate for towing purposes.No matter which class of tow hitch applies, for a
more safe trailer hookup, the trailer ball setup
must be the proper height for the coupler on the

Break-in schedule
If your vehicle is new or equipped with any new power train components (such as an
engine, transmission, differen tial or wheel bearing), Lexus recommends that you do not
tow a trailer until the vehicle has been driven for over 500 miles (800 km).
After the vehicle has been driven for over 500 miles (800 km), you can start towing.
However, for the next 500 miles (800 km), drive the vehicle at a speed of less than
50 mph (80 km/h) when towing a trailer, and avoid full throttle acceleration.■
Maintenance ●
If you tow a trailer, your vehicle will requir e more frequent maintenance due to the addi-
tional load. (See “Owner’s Guide”, “Warranty and Services Guide”, “Owner’s Manual
Supplement” or “Warranty Booklet”.) ●
Retighten the fixing bolts of the towing ba ll and bracket after approximately 600 miles
(1000 km) of trailer towing. ■
If trailer sway occurs
One or more factors (crosswinds, passing ve hicles, rough roads, etc.) can adversely
affect handling of your vehicle and trailer, causing instability. ●
If trailer swaying occurs:
• Firmly grip the steering wh eel. Steer straight ahead.
Do not try to control trailer sway ing by turning the steering wheel.
• Begin releasing the accelerator pedal im mediately but very gradually to reduce
speed.
Do not increase speed. Do not apply vehicle brakes.
If you make no extreme correction with the st eering or brakes, your vehicle and trailer
should stabilize. ●
After the trailer sw aying has stopped:
• Stop in a safe place. Get all occupants out of the vehicle.
• Check the tires of the vehicle and the trailer.
• Check the load in the trailer.
Make sure the load has not shifted.
Make sure the tongue weight is appropriate, if possible.
• Check the load in the vehicle.
Make sure the vehicle is not ov erloaded after occupants get in.
If you cannot find any problems, the speed at which trailer swaying occurred is beyond
the limit of your particular vehicle-trailer combination.
Drive at a lower speed to prevent instability. Remember that swaying of the towing vehi-
cle-trailer increases as speed increases.
