Driving
WARNING
■Handling of tires and the suspen- sion
Using tires with any kind of problem or modifying the suspension will affect the driving assist systems, and may
cause a system to malfunction.
■Trailer Sway Control precaution
The Trailer Sway Control system is not able to reduce trailer sway in all situations. Depending on many fac-
tors such as the conditions of the vehicle, trailer, road surface and driv-ing environment, the Trailer Sway
Control system may not be effective. Refer to your trailer owner’s manual for information on how to tow your
trailer properly.
■If trailer sway occurs
Observe the following precautions. Failing to do so may cause death or serious injury.
●Firmly grip the steering wheel. Steer straight ahead. Do not try to
control trailer sway 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 vehi-cle and trailer should stabilize.
( →P.152)
■Secondary Collision Brake
Do not rely solely upon the Secondary Collision Brake. This system is designed to help reduce the possibil-
ity of further damage due to a second- ary collision, however, that effect changes according to various condi-
tions. Overly relying on the system may result in death or serious injury.

6-1. Maintenance and care
NOTICE
●To prevent the wheels from corrod- ing, remove any dirt and store in a
place with low humidity when stor- ing the wheels.
■Cleaning the exterior lights
●Wash carefully. Do not use organic substances or scrub with a hard
brush. This may damage the surfaces of the lights.
●Do not apply wax to the surfaces of the lights.
Wax may cause damage to the lenses.
■To prevent damage to the wind-shield wiper arms
When lifting the wiper arms away
from the windshield, pull the driver side wiper arm upward first, and repeat for the passenger side. When
returning the wipers to their original position, do so from the passenger side first.
■When using an automatic car wash (vehicles with rain-sensing
windshield wipers)
Set the wiper switch to the off posi- tion. If the wiper switch is in “AUTO”,
the wipers may operate and the wiper blades may be damaged.
■When using a high pressure car wash
●Vehicles with rear view monitor sys-
tem: When washing the vehicle, do not spray the camera or its sur-rounding area directly with a high
pressure washer. Shock applied from high pressure water may cause the device to not operate
normally.
●Do not spray water directly on the
radar which is equipped behind the emblem. Otherwise it may cause the device to be damaged.
●Do not bring the nozzle tip close to boots (rubber or resin manufac-tured cover), connectors or the fol-
lowing parts. The parts may be damaged if they come into contact with high-pressure water.
• Traction related parts
• Steering parts
• Suspension parts
• Brake parts
●Keep the cleaning nozzle at least 30 cm (11.9 in.) away from the vehi-cles body. Otherwise resin section,
such as moldings and bumpers, may be deformed and damaged. Also, do not continuously hold the
nozzle in the same place.
●Do not spray the lower part of the
windshield continuously. If water enters the air conditioning system intake located near the lower part of
the windshield, the air conditioning system may not operate correctly.

■Does your vehicle need repairs?
Be on the alert for changes in perfor-
mance and sounds, and visual tip-offs
that indicate service is needed. Some
important clues are:
●Engine misses (misfire), stumbling or
pinging
●Appreciable loss of power
●Strange engine noises
●A fluid leak under the vehicle (How-
ever, water dripping from the air con-
ditioning system after use is normal.)
●Change in exhaust sound (This may
indicate a dangerous carbon monox-
ide leak. Drive with the windows open
and have the exhaust system checked
immediately.)
●Flat-looking tires, excessive tire
squeal when cornering, uneven tire
wear
●Vehicle pulls to one side when driven
straight on a level road
●Strange noises related to suspension
movement
●Loss of brake effectiveness, spongy
feeling brake pedal or clutch pedal
(vehicles with a manual transmission),
pedal almost touches the floor, vehicle
pulls to one side when braking
●Engine coolant temperature continu-
ally higher than normal (→P.86, 90)
If you notice any of these clues, take
your vehicle to any authorized Toyota
retailer or Toyota authorized repairer, or
any reliable repairer as soon as possi-
ble. Your vehicle may need adjustment

If your vehicle needs to
be towed
If towing is necessary, we rec-
ommend having your vehicle
towed by any authorized
Toyota retailer or Toyota autho-
rized repairer, or any reliable
repairer or commercial towing
service, using a wheel-lift type
truck or flatbed truck.
Use a safety chain system for
all towing, and abide by all
state/provincial and local laws.
WARNING
Observe the following precautions. Failure to do so may result in death or serious injury.
■When towing the vehicle
Be sure to transport the vehicle with
the front wheels raised or with all four wheels raised off the ground. If the vehicle is towed with the front wheels
contacting the ground, the drivetrain and related parts may be damaged.
■While towing
●When towing using cables or chains, avoid sudden starts, etc.
which place excessive stress on the towing eyelets, cables or chains. The towing eyelets, cables or
chains may become damaged, bro- ken debris may hit people, and cause serious damage.
●Do not turn the engine switch off.There is a possibility that the steer-
ing wheel is locked and cannot be operated.
■Installing towing eyelets to the vehicle
Make sure that towing eyelets are
installed securely. If not securely installed, towing eye-lets may come loose during towing.
NOTICE
■To prevent damage to the vehicle when towing using a wheel-lift type truck
●Do not tow the vehicle from the rear when the engine switch is off. The steering lock mechanism is not
strong enough to hold the front wheels straight.
●When raising the vehicle, ensure adequate ground clearance for tow-ing at the opposite end of the raised
vehicle. Without adequate clear- ance, the vehicle could be dam-aged while being towed.
■To prevent damage to the vehicle when towing with a sling-type
truck
Do not tow with a sling-type truck, either from the front or rear.
■To prevent damage to the vehicle during emergency towing
Do not secure cables or chains to the suspension components.
