CAUTIONS

If a vehicle get in front from adjacent lanes but not in the sensor monitoring area, the system may
not be able to detect the vehicle, resulting in lagging of SACC response. Pay close attention to the
vehicle movement in the adjacent lanes. Control your vehicle actively if necessary.

If the front car brakes suddenly (emergency stop), there will be a risk that SACC will not respond
or react too slowly, resulting in too late braking. In this case, you may not receive a request of
controlling your vehicle. Exercise extreme caution and control your vehicle actively if necessary.

If the target vehicle of SACC stops, it means the target vehicle may be screens or there is pedestrian
passing. Exercise extreme caution and control your vehicle actively if necessary.
Caution

SACC will keep the set distance with the vehicle ahead to follow the target. If the target vehicle
slows down and stops, SACC will control the vehicle to stop automatically.

When the target vehicle stops for less than 3s (seconds) and restarts or leaves the lane, the vehicle
will start automatically under the control of SACC.

When the target vehicle stops for more than 3s (seconds) but less than 3min (minutes) and starts or
leaves the lane again, the multi-function screen of the vehicle's instrument cluster will prompt the
information of resuming the cruise control. The driver can resume the SACC function by depressing
the accelerator pedal lightly or turning the cruise control handle to "RES+" to realize automatic
starting. At that time, the driver should pay attention to whether it is safe to start the vehicle.

SACC will automatically be canceled if the vehicle stops for over 3 min.

SACC cannot keep the vehicle in a braking state for a long time. Do not leave your vehicle while the
ACC keeps the vehicle stopped. Be sure to shift the selector lever in the P position before leaving your
vehicle.

The following items should be paid attention to when using SACC advanced cruise control for
turning:
●
In a sharp corner, the SACC may be canceled or limit the vehicle speed.
● On curves, advanced cruise control may react to vehicles in another lane, or may not have time to react to
vehicles in the same lane, may collide with the vehicle ahead, or lose control of the vehicle. Especially when
driving in a ramp, the vehicle may be accelerated since the system loses its target due to an excessive curve.
Pay special attention to the curve and be prepared to apply the brake if necessary. When driving on a curve,
select the appropriate speed.
● In the curve course, too small road radius may impact the judgment of SACC over the lane. When driving
on a curve, please drive carefully.

Drivers should pay attention to traffic light change when the vehicle follows a vehicle ahead through
the intersection with traffic lights, and should take the initiative to intervene when necessary to avoid
violating traffic rules.

When driving in heavy fog, rain, snow or other weather conditions, or there is frost and/or dirty
trace in the camera window area of the advanced driver assistance system, or when your vehicle is
moving in the direction toward the sun (or strong light source), the “the camera of the advanced driver
assistance system has been blocked, please clean the windshield” prompt may appear on the
combination instrument due to limited visual field of the camera. As a result, the SACC cannot work.
