Rear View Monitor  
▼
The rear view monitor provides visual  
images of the rear of the vehicle when  
reversing.  
WARNING  
Always drive carefully confirming the  
safety of the rear and the surrounding  
conditions by looking directly with  
your eyes:  
Reversing the vehicle by only looking at  
the screen is dangerous as it may cause  
an accident or a collision with an  
object. The rear view monitor is only a  
visual assist device when reversing the  
vehicle. The images on the screen may  
be diꢀerent from the actual conditions.  
If a camera lens is severely damaged  
by flying gravel, have the camera  
replaced. For camera replacement,  
consult an Authorized Mazda Dealer.  
NOTE  
CAUTION  
If water, snow, or mud is stuck on  
Do not use the rear view monitor  
under the following conditions:  
Using the rear view monitor under  
the following conditions is  
dangerous and could result in injury  
or vehicle damage or both.  
the camera lens, wipe it oꢀ using a  
soft cloth. If it cannot be wiped oꢀ,  
use a mild detergent.  
If the camera temperature changes  
rapidly (Hot to cold, cold to hot), the  
rear view monitor may not operate  
correctly.  
Icy or snow-covered roads.  
Tire chains or a temporary spare  
tire is installed.  
The vehicle is on a road incline.  
Bumpy roads.  
When the display is cold, images  
may course across the monitor or the  
screen and may be dimmer than  
usual, which could cause diꢁculty in  
confirming the surrounding  
conditions of the vehicle. Always  
drive carefully confirming the safety  
of the rear and the surrounding  
conditions by looking directly with  
your eyes.  
When replacing the tires, consult an  
Authorized Mazda Dealer. Replacing  
the tires could result in deviation of  
the guide lines which appear on the  
display.  
If the vehicle's front, side, or rear has  
been involved in a collision, the  
alignment of the rear view parking  
camera (location, installation angle)  
may have deviated. Always consult  
an Authorized Mazda Dealer to have  
the vehicle inspected.

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.  
4-235  
When Driving  
Rear View Monitor  
These lines are not displayed when the vehicle's wheels are in the straight-ahead  
position.  
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.  
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.  
4-236  
When Driving  
Rear View Monitor  
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 traꢁc, 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.

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 is tilted due to the weight of passengers and load  
When the vehicle rear is lowered, the object displayed on the screen appears farther  
than the actual distance.  
1. Object  
2. Variance  
3. Object on screen

When there is a steep grade behind the vehicle  
When there is a steep upgrade (downgrade) behind the vehicle, the object displayed  
on the screen appears farther (downgrade: closer) than the actual distance.  
1. Appears farther than actual distance  
2. Appears closer than actual distance  
3. Distance between the vehicle and object displayed on the screen.  
4. Actual distance between the vehicle and object.  
5. Object at actual position  
6. Object on screen  
Three-dimensional object on vehicle rear  
Because the distance guide lines are displayed based on a flat surface, the distance  
to the three-dimensional object displayed on the screen is diꢀerent from the actual  
distance.

When reversing near an overhanging object, the vehicle may hit the object even if  
the anticipated course line does not contact the object on the screen. The position  
of the object displayed on the screen is diꢀerent from the actual position because  
the anticipated course lines on the screen are displayed based on a horizontal road  
surface. When backing up near an overhanging object, confirm the rear and  
surrounding conditions directly with your eyes.
