

The distance appearing in the displayed image is different from the actual distance

because the rear view parking camera is equipped with a specific lens.

^ Images displayed on the monitor from the rear view parking camera are reversed

images (mirror images).

^ Some optionally installed vehicle accessories may be picked up by the camera. Do

not install any optional parts that can interfere with the camera view, such as

illuminating parts or parts made of reflective material.

^ It may be difficult to see the display under the following conditions, however, it

does not indicate a malfunction.

^ Image display may be delayed if the temperature around the camera is low.

▼ Viewing the Display

Predicted vehicle path assist lines display type

The projected path guidance mode displays the predicted path of the vehicle after

you turn the steering wheel.

Use this mode for parking your vehicle in a parking space or garage.

a) Projected vehicle path (yellow)

These lines are displayed as a reference for the projected path of the vehicle.

The lines displaying the projected vehicle path change after you turn the steering

wheel.

b) Extended vehicle width lines (blue)

These lines indicate the vehicle's extended width.

These lines are not displayed when the vehicle's wheels are in the straight-ahead

position.

4-226

When Driving

Rear View Monitor

c) Distance guide lines (red)

These lines indicate the approximate distance to a point measured from the

vehicle's rear (from the end of the bumper).

The blue line indicates the point about 0.5 m (19 in) from the rear bumper.

The red and yellow lines, which change position after you turn the steering wheel,

indicate the points about 0.5 m (19 in) for the red line and 1.0 m (39 in) and 2.0

m (78 in) for the yellow lines from the rear bumper (at the center point of each of

the lines).

A degree of error occurs when the wheels are not in the straight-ahead position.

In the above illustration, the right side of the vehicle is in a position closer to the

actual distance displayed by the distance guide lines (red: about 0.5 m (19 in)

point, yellow: about 1.0 m (39 in), and yellow: about 2.0 m (78 in) point behind

the rear bumper), whereas the left side is in a position farther away.

CAUTION

The indicated position of the guide lines on the display changes depending on the

vehicle conditions (such as the number of occupants/cargo load) and the road

conditions (such as a steep gradient to the rear of the vehicle).

Always check the area to the vehicle's rear and the surrounding area directly with

your eyes while backing up.

Fixed assist lines display type

Guide lines which indicate the width of the vehicle are displayed on the screen as a

reference to the approximate width of the vehicle in comparison to the width of the

parking space you are about to back into.

Use this display view for parking your vehicle in a parking space or garage.

a) Vehicle width guide lines

Guide lines serve as a reference to the approximate width of the vehicle.

4-227

When Driving

Rear View Monitor

b) Distance guide lines

These guide lines indicate the approximate distance to a point measured from the

vehicle's rear (from the end of the bumper).

The red line indicates the point about 0.5 m (19 in) from the rear bumper.

The yellow lines indicate the points about 1.0 m (39 in) and 2.0 m (78 in) from

the rear bumper.

CAUTION

The guide lines on the screen are fixed lines. They are not synced to the driver's

turning of the steering wheel. Always be careful and check the area to the vehicle's

rear and the surrounding area directly with your eyes while backing up.

▼ Rear View Monitor Operation

The operation of the rear view monitor when reversing the vehicle varies depending

on the traffic, road, and vehicle conditions. The amount of steering and the timing

also varies depending on conditions, so confirm the surrounding conditions directly

with your eyes and steer the vehicle in accordance with the conditions.

Be well aware of the above cautions prior to using the rear view monitor.

Predicted vehicle path assist lines display type

NOTE

The following shows an example of vehicle parking in which the steering wheel is

turned to the right when backing up the vehicle. The operation is reversed when

backing up the vehicle from the opposite direction.

1. Shift the shift lever (manual transmission) or the selector lever (automatic

transmission) to reverse (R) position to switch the display to the rear view

monitor display.

5. Once they are parallel, straighten the wheels and back your vehicle slowly into

the parking space. Continue checking the vehicle's surroundings and then stop

the vehicle in the best possible position. (If the parking space has division lines,

check whether the vehicle width guide lines are parallel to them.)

(Vehicle condition)

6. When the shift lever (manual transmission) or the selector lever (automatic

transmission) is shifted from reverse (R) position to another shift lever (manual

transmission) or the selector lever (automatic transmission) position, the screen

NOTE

Because there may be a difference between the displayed image, such as indicated

below, and the actual conditions when parking, always verify the safety at the rear of

the vehicle and the surrounding area directly with your eyes.

^ In the image of the parking space (or garage) displayed on the screen, the back

end and distance guide lines may appear aligned in the monitor, but they may not

actually be aligned on the ground.

▼ Variance Between Actual Road Conditions and Displayed Image

Some variance occurs between the actual road and the displayed road. Such

variance in distance perspective could lead to an accident. Note the following

conditions that may cause a variance in distance perspective.

When the vehicle rear is lowered, the object displayed on the screen appears farther

than the actual distance.
