■ Cautions regarding the use of the system
There is a limit to the degree of recognition accuracy and cont rol perfor-
mance that this system can provide, do not overly rely on this system. The
driver is always responsible for paying attention to the vehicl e’s surround-
ings and driving safely. ( P. 294)

2984-5. Using the driving support systems
■The Rear Cross Traffic Alert function is operational when
● The BSM main switch is set to on.
● The shift lever is in R.
● Vehicle speed is less than approximately 5 mph (8 km/h).
● Approaching vehicle speed is between approximately 5 mph (8 km/ h) and
18 mph (28 km/h).
■ 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 the 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 conditions, detection of a vehicle and/or object may occur.
■ Situations in which the syst em may not operate properly
The RCTA function may not detect vehicles correctly in the foll owing situa-
tions:
● 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
● 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
●
Vehicles that the sensors cannot detect
due to obstructions

Driving
●When towing a trailer
● When there is a significant difference in height between your vehicle and the
vehicle that enters the detection area
● When a sensor or the area around a sensor is extremely hot or c old
● If the suspension has been modified or tires of a size other th an specified
are installed
● If the front of the vehicle is raised or lowered due to the car ried load
●
When backing up on a slope with a
sharp change in grade
● When backing out of a sharp angle park-
ing spot
● When turning while backing up

■Situations in which the system may operate even if there is no possibil-
ity of a collision
Instances of the RCTA function unnecessary 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
●
Vehicles that the sensors cannot detect
due to obstructions
● 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, sigh, 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

3014-5. Using the driving support systems

Driving
●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
sprinkler
● Moving objects (flags, exhaust fumes, large rain droplets or sn owflakes, rain
water on the road surface, etc.)
● When the distance between your vehicle and a guardrail, wall, etc., that
enters the detection area is short
● Gratings and gutters
● When a sensor or the area around a sensor is extremely hot or c old
● If the suspension has been modified or tires of a size other th an specified
are installed
● If the front of the vehicle is raised or lowered due to the car ried load
●
When a detected vehicle turns while
approaching the vehicle

3024-5. Using the driving support systems
Four-wheel drive system
Use the front-wheel drive control switch to select the following transfer
modes:
“2WD” (high speed position, two-wheel drive)
Use this for normal driving on dry hard-surfaced roads. This po sition
gives greater economy, quietest ride and least wear.
“4H” (high speed position, four-wheel drive)
Use this for driving only on tracks that permit the tires slide, like off-road,
icy or snow-covered roads. This position provides greater traction than
two-wheel drive.
The four-wheel drive indicator will come on.
“4L” (low speed position, four-wheel drive)
Use this for maximum power and traction. Use “4L” for climbing or
descending steep hills, off-road driving, and hard pulling in s and, mud or
deep snow.
The four-wheel drive and “4LO” indicator will come on.
