14. If the entertainment navigation system fails (power block-up, no picture, no voice) or any abnormal status (foreign matter inside

the system, water entering the system, smoke, or smell), do not open the machine shell without permission. after removing the
body, lubricate the rotating parts. The power supply should be immediately cut off and contact authorized service center for
repair.

11.3.6.3 Navigation Notice

1. Because there are individual differences in each vehicle in the navigation system's initial use, it needs the calibration time for

more accurate positioning of the vehicle. In driving, the system automatically and dynamically calibrate.

2. After shut down the engine for a long time, when restart the navigation system receiving GPS signals and re-positioning time

will be longer. in general, the vehicle can be successfully positioned within 3min .

3. If  the  GPS  signals  are  shielding  such  as:  high-rise  buildings  on  either  side  of  the  road,  roadside  trees,  under  overpasses,

underground car parks, tunnels. at this time the GPS signals can not be received, and the positioning is also possibly biased.

4. It may sometimes not be able to identify the vehicles on the elevated road or on the ground. Over time, the vehicle will be re-

positioned correctly.

5. To avoid excessive invalid voice order, at some turns there are no voice prompts: If there is no bifurcation of the turning point of

intersection or the difference between the level of the road is too great.

6. If one was transferred to the road next to the other parallel road, then the voice will prompt"Turn at x to y" in order to help choose

the right turn. Side roads will be counted as an intersection.

7. In the routes calculation, the address input, switching languages, day and night mode switching points of interest search, disc

insert and eject operations require more system resources and need to wait for a period of time to complete. it is recommended
that when doing these operations, do not turn the ignition or switch interface or plug SD card, otherwise it will affect the system
stability. Under serious situation, system may restart.

8. To avoid navigation system not turned off and hot plug SD card, causing the SD card file system damage, lost, resulting in the

normal navigation system can not read the map files for navigation, it is prohibit to hot plug the SD card.

11.3.6.4 Navigation Non-Fault Status, The Positioning Amendment

Note

The following list is not the navigation malfunction. If it occurs, after test the vehicle and verify the problem, explain to
customers.

Step 1

Y-shaped Road

Y-shape Divided Roads

FE11-5206b

On the Y-shaped road or similar roads, the sensor driving direction
accumulated error may lead to the current location marker appears
in the wrong path.

Correction

Continuously driving for some time, after
divergent roads, the vehicle will be re-
positioned correctly.

Step 2

Spiral-shaped Road

Spiral Road

FE11-5207b

When traveling on a large, continuous spiral road (for example, ring
overpasses, etc.), there will be turning point accumulated errors,
the location marker may deviate from the current location.

Correction

Continuously driving for some time, after
divergent roads, the vehicle will be re-
positioned correctly.

Step 3

Turning A Corner After The Straight Road

Straight Road

FE11-5208b

When traveling on a long, straight road, the map matching can not
be effective enough to work and may thus accumulate error in
distance. Therefore, when the vehicle turning a corner, the location
marker may deviate from the current location.

Correction

Continuously driving for some time, after
divergent roads, the vehicle will be re-
positioned correctly. When turning, maintain
a low constant speed to avoid such problems.

Step 4

Zigzag Round-Trip Route

Zigzag Road

FE11-5209b

When traveling on a zig-zag road, at each turn the map may be
matched to other nearby roads in the same direction, then the
location marker may deviate from the current location.

Correction

Continuously driving for some time, after
divergent roads, the vehicle will be re-
positioned correctly.

Step 5

Square-shaped Road

Square Blocks

FE11-5210b

When traveling on a square-shaped road, there are many roads in
the vicinity to the same direction, the map may be matched to other
roads, then the location marker may deviate from the current
location.

Correction

Continuously driving for some time, after
divergent roads, the vehicle will be re-
positioned correctly.

Step 6

Parallel Roads

Parallel Roads

FE11-5211b

When the two roads are parallel(for example, there is a side road
next to the highway.), map may be incorrectly matched to other
roads, then the location marker may deviate from the current
location.

correction method

Continuously driving for some time, after
divergent roads, the vehicle will be re-
positioned correctly.

Step 7

In The Parking Lot

Inside Parking Lot

Parking Lot

FE11-5212b

When the vehicle is in a parking lot or on an unnamed road, the
current location marked as a nearby road. When the vehicle is back
on the road, the location marker may deviate from the correct
location.

Correction

Continuously driving for some time, after
divergent roads, the vehicle will be re-
positioned correctly.

Step 8

Steep Hills, Slopes

Slope

FE11-5213b

When parking on slopes or on a steep hill, the turning point will have
error and the location marker may deviate from the correct location.

Correction

Continuously driving for some time, after
divergent roads, the vehicle will be re-
positioned correctly.

Step 9

Erratic Driving Route

When the vehicle changes lane frequently, the location marker may
deviate from the correct location.

Correction

Continuously driving for some time, after
divergent roads, the vehicle will be re-
positioned correctly.

Step 10

Map Data Related

Not Displayed Road

New Road

Different Road 

Pattern

(Changed Due to 

Road Work)

FE11-5214b

(a)

When traveling on a new road, or the the road that does not
show on the screen, map matching can not be functioning
properly, thus matching the other roads nearby, the marker
point may be deviated from the correct location.

(b)

B. If the data stored in the road map is different from the actual
road shape, normal map-matching does not work, thus
matching other roads nearby, the location marker may be
deviate from the correct location.

Correction

Continuously driving for some time, after
divergent roads, the vehicle will be re-
positioned correctly.
