WARNING
■SRS airbag precautions
● If breathing becomes difficult after the SRS airbags have deployed, open a
door or side window to allow fresh air in, or leave the vehicle if it is safe to
do so. Wash off any residue as soon as possible to prevent skin irritation.
● If the areas where the SRS airbags are stored, such as the steering wheel
pad and front and rear pillar garnishes, are damaged or cracked, have
them replaced by your Toyota dealer.
● Do not place anything, such as a cushion, on the front passenger’s seat.
Doing so will disperse the passenger’s weight, which prevents the sensor
from detecting the passenger’s weight properly. As a result, the SRS front
airbags for the front passenger may not deploy in the event of a collision.
■ Modification and disposal of SRS airbag system components
Do not dispose of your vehicle or perform any of the following modifications
without consulting your Toyota dealer. The SRS airbags may malfunction or
deploy (inflate) accidentally, causing death or serious injury.
● Installation, removal, disassembly and repair of the SRS airbags
● Repairs, modifications, removal or replacement of the steering wheel,
instrument panel, dashboard, seats or seat upholstery, front, side and rear
pillars, roof side rails, front door panels, front door trims or front door
speakers
● Modifications to the front door panel (such as making a hole in it)
● Repairs or modifications of the front fender, front bumper, or side of the
occupant compartment
● Installation of a grille guard (bull bars, kangaroo bar, etc.), snow plows,
winches or roof luggage carrier
● Modifications to the vehicle’s suspension system
● Installation of electronic devices such as mobile two-way radio s and CD
players
● Modifications to your vehicle for a person with a physical disability

■Conditions under which the system will not detect a vehicle
The Rear Cross Traffic Alert function is not designed to detect the following
types of vehicles and/or objects:
● Vehicles approaching from directly behind
● Vehicles backing up in a parking space next to your vehicle
● Guardrails, walls, signs, parked vehicles and similar stationar y objects
*
●Small motorcycles, bicycles, pedestrians, etc.*
●Vehicles moving away from your vehicle
● Vehicles approaching from the parking spaces next to your vehic le
*
●The distance between the sensor and approaching vehicle gets to o close
*: Depending on the conditions, detection of a vehicle and/or obj ect may
occur.
■ Situations in which the syst em may not operate properly
The Rear Cross Traffic Alert function may not detect vehicles c orrectly in the
following situations:
● When the sensor is misaligned due to a strong impact to the sensor or its
surrounding area
● When mud, snow, ice, a sticker, etc. is covering the sensor or surrounding
area on the position above the rear bumper
● When driving on a road surface that is wet with standing water during bad
weather, such as heavy rain, snow, or fog
● When multiple vehicles are approaching with only a small gap be tween
each vehicle
● When a vehicle is approaching at high speed

snow plow
●
Vehicles that the sensors cannot detect

■Situations in which the system may operate even if there is no possibil-
ity of a collision
Instances of the Rear Cross Traffic Alert function unnecessaril y detecting a
vehicle and/or object may increase in the following situations:
● When equipment that may obstruct a sensor is installed, such as a towing
eyelet, bumper protector (an additional trim strip, etc.), bicy cle carrier, or
snow plow
● When there are spinning objects near your vehicle such as the f an of an air
conditioning unit
● When water is splashed or sprayed toward the rear bumper, such as from a

● Moving objects (flags, exhaust fumes, large rain droplets or snowflakes, rain
water on the road surface, etc.)
●
When the parking space faces a street
and vehicles are being driven on the
street
● When the distance between your vehicle
and metal objects, such as a guardrail,
wall, sign, or parked vehicle, which may
reflect electrical waves toward the rear
of the vehicle, is short
● When a vehicle passes by the side of
your vehicle
● When a detected vehicle turns while
approaching the vehicle

4-5. Using the driving support systems
●If the orientation of a sensor has been changed due to a collis ion or other
impact
● When equipment that may obstruct a sensor is installed, such as a towing
eyelet, bumper protector (an additional trim strip, etc.), bicy cle carrier, or
snow plow
● If the front of the vehicle is raised or lowered due to the car ried load
● If the vehicle cannot be driven in a stable manner, such as whe n the vehicle
has been in an accident or is malfunctioning
● When tire chains, a compact spare tire or an emergency tire pun cture repair
kit are used.
■ Situations in which the system may operate even if there is no possibil-
ity of a collision
In some situations, such as the following, the system may opera te even
though there is no possibility of a collision.
● When driving toward a banner, flag, low-hanging branch or boom barrier
(such as those used at railroad crossings, toll gates and parking lots)
● When there is a rut or hole in the surface of the road
● When driving on a metal cover (grating), such as those used for drainage
ditches
● When driving up or down a steep slope
● If a sensor is hit by a large amount of water, such as when dri ving on a
flooded road
● There is dirt, snow, water drops or ice on a sensor. (Cleaning the sensors
will resolve this problem.)
● A sensor is coated with a sheet of spray or heavy rain
● When driving in inclement weather such as fog, snow or a sandst orm
●
When driving on a narrow road
● When strong winds are blowing

● When inspecting the vehicle using a chassis roller, chassis dynamo or free
roller
● When loading the vehicle onto a boat, truck or other transport vessel
● If the suspension has been modified or tires of a size other than specified
are installed
● If the front of the vehicle is raised or lowered due to the carried load
● When equipment that may obstruct a sensor is installed, such as a towing
eyelet, bumper protector (an additional trim strip, etc.), bicycle carrier, or
snow plow
● When using automatic car washing devices
● If the vehicle cannot be driven in a stable manner, such as when the vehi-
cle has been in an accident or is malfunctioning
● When the vehicle is driven in a sporty manner or off-road

■ To ensure the system can operate properly
 P. 368
■ Handling the suspension
Do not modify the suspension, as changes to the height or incli ne of the
vehicle may prevent the sensors from correctly detecting obstac les, may
cause the system not operate, or may cause the system to operat e unnec-
essarily.
■ If the Parking Support Brake function (static objects) operates unnec-
essarily, such as at a railroad crossing
