Driving
■Maintenance
●If you tow a trailer, your vehicle will require more frequent m aintenance 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 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 control trailer swaying by turning the steering w heel.
• Begin releasing the accelerator pedal immediately but very gra dually 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.
● 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.
If you cannot find any problems, the speed at which trailer swaying occurred
is beyond the limit of your particular vehicle-trailer combinat ion.
Drive at a lower speed to prevent instability. Remember that sw aying of the
towing vehicle-trailer increases as speed increases.

6-1. Maintenance and care
Cleaning and protecting the vehicle exterior
●Working from top to bottom, liberally apply water to the vehicl e
body, wheel wells and underside of the vehicle to remove any di rt
and dust.
● Wash the vehicle body using a sponge or soft cloth, such as a
chamois.
● For hard-to-remove marks, use car wash soap and rinse thoroughl y
with water.
● Wipe away any water.
● Wax the vehicle when the wate rproof coating deteriorates.
If water does not bead on a clean surface, apply wax when the vehicle
body is cool.
■Automatic car washes
●Before washing the vehicle:
• Fold the mirrors.
• Turn off the power back door system. (if equipped)
• Turn off the power sliding door system. (if equipped)
Start washing from the front of the vehicle. Make sure to extend the mirrors
before driving.
● Brushes used in automatic car washes may scratch the vehicle su rface and
harm your vehicle’s paint.
■ High pressure car washes
●Do not allow the nozzles of the car wash to come within close p roximity of
the windows.
● Before using the car wash, check that the fuel filler door on y our vehicle is
closed properly.
■ When using a car wash (vehicles with a smart key system)
●If the door handle becomes wet while the electronic key is with in the effec-
tive range, the door may lock and unlock repeatedly. Place the key in a posi-
tion 6 ft. (2 m) or more separate from the vehicle while the ve hicle is being
washed. (Take care to ensure that the key is not stolen.)
● If the electronic key is inside the vehicle and a door handle b ecomes wet

Maintenance and care
■Aluminum wheels
●Remove any dirt immediately by using a neutral detergent.
● Wash detergent off with water immediately after use.
● To protect the paint from damage, make sure to observe the following pre-
cautions.
• Do not use acidic, alkaline or abrasive detergent
• Do not use hard brushes
• Do not use detergent on the wheels when they are hot, such as after driv-
ing or parking in hot weather
■ Bumpers and side moldings
Do not scrub with abrasive cleaners.
WARNING
■When washing the vehicle
Do not apply water to the inside of the engine compartment. Doing so may
cause the electrical components etc. to catch fire.
■ When cleaning the windshield (veh icles with rain-sensing windshield
wiper)
● When the upper part of the windshield where the raindrop sensor is
located is touched by hand
● When a wet rag or similar is held close to the raindrop sensor
● If something bumps against the windshield
● If you directly touch the raindrop sensor body or if something bumps into
the raindrop sensor
■ Precautions regarding the exhaust pipe
Exhaust gasses cause the exhaust pipe to become quite hot.
When washing the vehicle, be careful not to touch the pipe unti l it has
cooled sufficiently, as touching a hot exhaust pipe can cause b urns.
■ Precaution regarding the Blind Spot Monitor (if equipped)
If the paint of the rear bumper is chipped or scratched, the sy stem may mal-
function. If this occurs, consult your Toyota dealer.
Set the wiper switch to off.
If the wiper switch is in “AUTO”, the wip-
ers may operate unexpectedly in the fol-
lowing situations, and may result in
hands being caught or other serious inju-
ries and cause damage to the wiper
blades.
