vehicle, and it may alert for pedestri ans, bicycles, or stationary objects.
■How the System Works1Cross Traffic Monitor*
Cross Traffic Monitor may not detect or may delay
alerting an approaching vehi cle, or may alert without

conditions:
•An obstacle, such as a nother vehicle and a wall,
near your vehicle’s rear bumper, is blocking the
radar sensor’s scope.
•Your vehicle is moving at the speed of about 3 mph
(5 km/h) or higher.
•A vehicle is approaching at the speed other than
between about 6 mph (10 km/h) and 16 mph
(25 km/h).
•The system picks up external interference such as
other radar sensors from an other vehicle or strong
radio wave transmitted fr om a facility nearby.
•Either corner of the rear bumper is covered with
snow, ice, mud or dirt.
•When there is bad weather.
•Your vehicle is on an incline.
•Your vehicle is tilted due to a heavy load in the rear.•Your vehicle is reversing towards a wall, a pole, a
vehicle, and so on.

Item
*1: If the message
Maintenance Due Now does not appear more than 12 months after the display
is reset, change the engine oil every year.
# : See information on maintenance and emissions warranty in the first column on page 575.
*2: If you drive in dusty conditions, replace the air cleaner element every 15,000 miles (24,000 km).
*3: If you drive primarily in urban areas that have high concentrations of soot in the air from industry and from diesel-powered vehicles, replace every 15,000 miles (24,000 km).

●Inspect fuel lines and connections#
*4: Driving in mountainous areas at very low vehicle speeds or trailer towing results in higher transmission
temperatures. This requires transmission fluid changes more frequently than recommended by the
Maintenance Minder
TM. If you regularly drive your vehicle under these conditions, have the transmission
fluid changed at every 30,000 miles (48,000 km) or 2 years.
*5: If you drive regularly in very high temperatures (over 110°F, 43°C), in very low temperatures (under
-20°F, -29°C), or towing a trailer, replace every 60,000 miles (U.S.) / 100,000 km (Canada).
*6: Driving in mountainous areas at very low vehicle speeds or trailer towing results in higher level of mechanical (Shear) stress to fluid. This requires differential fluid changes more frequently than
recommended by the Maintenance Minder
TM. If you regularly drive your vehicle under these conditions,
have the differential fluid changed at 7,500 miles (12,000 km), then every 15,000 miles (24,000 km).
