When driving
■
Break-in schedule
If your vehicle is new or equipped with any new power train components
(such as an engine, transmission, differential or wheel bearing), Toyota rec-
ommends 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 s\
tart
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 require more frequent maintenance
due to the additional load. (See “Owner’s Warranty Information Booklet”
or “Scheduled Maintenance Guide/Owner’s Manual Supplement”.)
● Retighten the fixing bolts of the towing ball and bracket after approxi-
mately 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 control trailer swaying by turning the steering wheel.
• Begin releasing the accelerator pedal immediately but very gradually 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 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 overloaded after occupants get in.

458 3-5. Other interior features
CAUTION
Observe the following precautions.
Failure to do so may cause the driver’s floor mat to slip, possibly interfering
with the pedals while driving. An unexpectedly high speed may result or it may
become difficult to stop the vehicle, leading to a serious accident.
■When installing the driver’s floor mat
●Do not use floor mats designed for other models or different model year
vehicles, even if they are Toyota Genuine floor mats.
● Only use floor mats designed for the driver’s seat.
● Always install the floor mat securely using the retaining hooks (clips) pro-
vided.
● Do not use two or more floor mats on top of each other.
● Do not place the floor mat bottom-side up or upside-down.
■ Before driving
●Check that the floor mat is securely
fixed in the correct place with all the
provided retaining hooks (clips). Be
especially careful to perform this check
after cleaning the floor.
● With the engine stopped and the shift
lever in P, fully depress each pedal to
the floor to make sure it does not inter-
fere with the floor mat.
