Speed Limit Information Function (SLIF): The vehicle

detects a speed limit sign (as shown above) at the

roadside with the front view camera. The speed limit

sign identiﬁed will be displayed on the instrument pack.

When the vehicle speed exceeds the speed limit by a

preset amount, a visual warning in the instrument pack

will alert the driver to control the speed manually.

The intelligent speed limit is an auxiliary

function, it may display an incorrect speed

limit value or no speed limit value in the

instrument pack due to various factors. As

a result, the vehicle speed is not restricted

within the correct range. The driver still

needs to observe the speed limit of the road

trafﬁc, and speeding is strictly prohibited.

Manual Speed Assist (MSA): The driver sets the

maximum speed using the adaptive cruise control

lever. The system will actively intervene and keep the

vehicle speed within the permitted maximum speed

limit. And an acoustic warning and a visual warning

will be available during the intervention. Please refer

to the section “Speed settings of manual speed assist”.

The front view camera cannot recognise

speed limit signs painted on the road surface.

The driver MUST observe these speed limits

and adjust the their speed accordingly.

Intelligent Speed Assist (ISA): The vehicle detects a

speed limit sign (as shown above) at the roadside

with the front view camera. The speed limit sign

identiﬁed will be displayed on the instrument pack.

The system will automatically intervene and maintain

speed control to keep the vehicle speed within the

permitted maximum speed limit. And an acoustic

OK button to turn on/off the speed limit information

function.

Note: It is recommended to switch off the speed

limit information function and intelligent speed assist

function when the km/h speed units are selected. In

such situations, the system will only recognize the

number displayed in all speed limit signs and use this

data for km/h, even if the speed limit sign refers to

mph. When km/h is selected, the system will also

recognize the national speed limit sign as a speed limit

sign of 60km/h.

recognise the speed limit sign with text messages as a

normal speed limit sign. The driver is required to make

correct judgement according to the text message.
