2024-1. Before driving
●All trailer lights work as required 
by law.
●All lights work each time you con-
nect 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 
tongue weight, overloading, worn 
suspension, or other possible 
causes.
●The trailer cargo is securely 
loaded.
●The rear view mirrors conform to 
all applicable federal, state/provin-
cial or local regu lations. If they do 
not, install rear  view mirrors 
appropriate for towing purposes.
■Break-in schedule
If your vehicle is new or equipped 
with any new power train compo-
nents (such as an engine, hybrid 
transmission, rear differential or 
wheel bearing), Toyota 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 vehi-
cle 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 require more f requent mainte-
nance due to the additional load. 
(See “Scheduled Maintenance 
Guide” or “Owner’s Manual Sup-
plement”.)
●Retighten the fixing bolts of the 
towing ball and bracket after 
approximately 600 miles (1000 
km) of trailer towing.
■If trailer sway occurs
One or more factors (crosswinds, 
passing vehicles, rough roads, etc.) 
can adversely affect handling of 
your vehicle and trailer, causing 
instability.
●If trailer swaying occurs:
• Firmly grip the steering wheel.  Steer straight ahead.
Do not try to contr ol trailer sway-
ing by turning the steering wheel.
• Begin releasing the accelerator  pedal immediately but very gradu-
ally to reduce speed.
Do not increase speed. Do not 
apply vehicle brakes.
If you make no extreme correction 
with the steering or brakes, your 
vehicle and trailer  should stabilize. 
(if enabled, Trailer Sway Control can 
also help to stabilize the vehicle and 
trailer.)
●After the trailer swaying has 
stopped:
• Stop in a safe place. Get all occu- pants 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 over-
loaded 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 combina-
tion. Drive at a lower speed to pre-
vent instability. Remember that 
swaying of the towing vehicle-trailer 
increases as speed increases.
