WARNING
■To avoid accident or injury
●Do not use cruise control when towing.
● Slow down and downshift before descending steep or long downhill
grades. Do not make sudden downshifts while descending steep or long
downhill grades.
● Vehicle-trailer instability is more likely on steep long downhills. Before
descending steep or long downhill grades, slow down and downshift. Do
not make sudden downshifts when descending steep or long downhill
grades. Avoid holding the brake pedal down too long or applying the
brakes too frequently. This could cause the brakes to overheat and result
in reduced braking efficiency.
● Vehicles with compact spare tire: Do not tow a trailer when the compact
spare tire is installed on your vehicle.
■ Hitch
Trailer hitch assemblies have different weight capacities established by the
hitch manufacturer. Even though the vehicle may be physically capable of
towing a higher weight, the operator must determine the maximum weight
rating of the particular hitch assembly and never exceed the maximum
weight rating specified for the trailer-hitch. Exceeding the maximum weight
rating set by the trailer-hitch manufacturer can cause an accident resulting
in death or serious personal injuries.
■ When towing a trailer
Toyota recommends trailers with brakes that conform to any applicable fed-
eral and state/provincial regulations.
●If the gross trailer weight exceeds unbraked TWR, trailer brakes are
required. Toyota recommends trailers with brakes that conform to all appli-
cable federal and state/provincial regulations.
● Never tap into your vehicle’s hydraulic system, as this will lower the vehi-
cle’s braking effectiveness.
● Never tow a trailer without using a safety chain securely attached to both
the trailer and the vehicle. If damage occurs to the coupling unit or hitch
ball, there is danger of the trailer wandering into another lane.
NOTICE
■When installing a trailer hitch
Use only the position recommended by your Toyota dealer. Do not install
the trailer hitch on the bumper; this may cause body damage.
■ Do not directly splice trailer lights
Do not directly splice trailer lights. Directly splicing trailer lights may damage
your vehicle’s electrical system and cause a malfunction.

Driving
The fixed guide lines are very far out of alignment
The camera position is out of align-
ment.Have the vehicle inspected by your
Toyota dealer.
• The vehicle is tilted (there is a
heavy load on the vehicle, tire
pressure is low due to a tire punc-
ture, etc.)
• The vehicle is used on an incline.If this happens due to these causes,
it does not indicate a malfunction.
Back up while visually checking the
vehicle’s surroundings.
WARNING
■ When using the rear view monitor system
The rear view monitor system is a supplemental device intended to assist
the driver when backing up. When backing up, be sure to check visually
behind and all around the vehicle before proceeding.
Observe the following precautions to avoid an accident that could result in
death or serious injuries.
● Never depend on the rear view monitor system entirely when backing up.
The image and the position of the guide lines displayed on the screen may
differ from the actual state.
Use caution, just as you would when backing up any vehicle.
● Be sure to back up slowly, depressing the brake pedal to control vehicle
speed.
● The instructions given are only guide lines.
When and how much to turn the steering wheel will vary according to traf-
fic conditions, road surface conditions, vehicle condition, etc. when park-
ing. It is necessary to be fully aware of this before using the rear view
monitor system.
● When parking, be sure to check that the parking space will accommodate
your vehicle before maneuvering into it.
● Do not use the rear view monitor system in the following cases:
• On icy or slick road surfaces, or in snow
• When using tire chains or the compact spare tire (if equipped)
• When the back door is not closed completely
• On roads that are not flat or straight, such as curves or slopes.

Tires
Check if the treadwear indicators are showing on the tires. Also check
the tires for uneven wear, such as excessive wear on one side of the
tread. Check the spare tire condi tion and pressure if not rotated.
New tread
Worn tread
Treadwear indicator
The location of treadwear indicators is shown by a “TWI” or “ ” marks,
etc., molded into the sidewall of each tire.
Replace the tires if the treadwear indicators are showing on a tire.
Rotate the tires in the order
shown.
To equalize tire wear and extend
tire life, Toyota recommends that
tire rotation is carried out at the
same interval as tire inspection.
Replace or rotate tires in acco rdance with maintenance sched-
ules and treadwear.

Maintenance and care
Your vehicle is equipped with a tire pressure warning system that uses
tire pressure warning valves and tr ansmitters to detect low tire infla-
tion pressure before serious problems arise. ( P. 547)
Vehicles with compact spare tire : The compact spare tire is not
equipped with the tire pressure warning valve and transmitters.
◆Installing tire pressure warning valves and transmitters
When replacing tires or wheels, tire pressure warning valves and
transmitters must also be installed.
When new tire pressure warning valves and transmitters are
installed, new ID codes must be registered in the tire pressure
warning computer and the tire pr essure warning system must be
initialized. Have tire pressure warning valve and transmitter ID
codes registered by your Toyota dealer. ( P. 498)
◆Initializing the tire pressure warning system
When the tire size is changed, the tire pressure warning system
must be initialized.
When the tire pressure warning system is initialized, the current tire
inflation pressure is set as the benchmark pressure.
■How to initialize the tire pressure warning system
Park the vehicle in a safe place and turn the engine switch off.
Initialization cannot be performed while the vehicle is moving.
Adjust the tire inflation pressure to the specified cold tire inflation
pressure level. ( P. 606)
Make sure to adjust the tire pressu re to the specified cold tire infla-
tion pressure level. The tire pressure warning system will operate
based on this pressure level.
Turn the engine switch to the “ON” position (vehicles without a
smart key system) or IGNITION ON mode (vehicles with a smart
key system).

WARNING
■When inspecting or replacing tires
Observe the following precautions to prevent accidents. Failure to do so
may cause damage to parts of the drive train, as well as dangerous han-
dling characteristics, which may lead to an accident resulting in death or
serious injury.
●Do not mix tires of different ma kes, models or tread patterns.
Also, do not mix tires of remarkably different treadwear.
●Do not use tire sizes other than those recommended by Toyota.
●Do not mix differently constructed ti res (radial, bias-belted or bias-ply
tires).
●Do not mix summer, all season and snow tires.
●Do not use tires that have b een used on another vehicle.
Do not use tires if you do not know how they were used previously.
●Vehicles with a compact spare tire: Do not tow if your vehicle has a
compact spare tire installed.
■When initializing the tire pressure warning system
Do not operate the tire pressure warning reset switch without first
adjusting the tire inflation pressure to the specified level. Otherwise, the
tire pressure warning light may not come on even if the tire inflation
pressure is low, or it may come on when the tire inflation pressure is
actually normal.

Maintenance and care
Tire valve
Tire pressure gauge
Remove the tire valve cap.
Press the tip of the tire pressure gauge onto the tire valve.
Read the pressure usi ng the gauge gradations.
If the tire inflation pressure is not at the recommended level, adjust
the pressure.
If you add too much air, press the center of the valve to deflate.
After completing the tire inflation pressure measurement and
adjustment, apply soapy water to the valve and check for leakage.
Put the tire valve cap back on.
■Tire inflation pressure check interval
You should check tire inflation pressure every two weeks, or at least once
a month.
Do not forget to check the spare.
■Effects of incorrect tire inflation pressure
Driving with incorrect tire inflation pressure may result in the following:
●Reduced fuel economy
●Reduced driving comfort and poor handling
●Reduced tire life due to wear
●Reduced safety
●Damage to the drive train
If a tire needs frequent inflating, have it checked by your Toyota dealer.
