Geely Emgrand X7. Manual part — 312

In manual mode function, in order to prevent the low engine speed from affecting the normal engine operation
and safety, the upshift with manual mode function needs to meet certain speed requirements; otherwise, upshift
action will not be executed. The following table is the minimum upshift speed (actual speed may have smaller
deviation) in the manual mode.

In manual mode function, in order to prevent the excessive engine speed from affecting the normal engine
operation and safety, the downshift needs to meet certain speed requirements; otherwise, downshift action will
not be executed. The following table is the minimum upshift speed (actual speed may have smaller deviation) in
the manual mode.

When the shift level in the uplift position or downlift position exceeds 500ms, the system defaults that the driver
hopes to operate at the maximum or minimum gear position. At this time, even if the manual operation is not
done any more, the gear also automatically gradually switch the maximum or minimum gear shifts allowed by
the current speed.

When the position of the accelerator pedal exceeds 80%, the system will withdraw from the manual mode, and
at this tie, the control strategy of the gear D will be performed.

During manual shift, the automatic transmission may be slightly impacted; however, it is not sure that the
automatic transmission is broken down.

When the shift level is in the position M, the driver can define the applicable gear positions through + or - on
the level. When initially moving the control level to the manual M position, the transmission will maintain the
current gear position.

When reaching the maximum of revolution speed of the engine, the transmission will automatically shift up no
matter how the driver selects the gear position.

State of 1st speed

The combination instrument displays the state of 1st speed. Engine brake can be used when the shift gear is in
Manual 1st speed position different from Automatic 1st speed .

State of the 2nd speed

The combination instrument displays the state of the 2nd speed. Be capable of realizing 2-1 automatic kickdown
through anxiously stepping on the accelerator pedal to the end. The engine brake can be used for the 2nd speed.

State of the 3rd speed

The combination instrument displays the state of the 3rd speed. Be capable of realizing 3-1 or 3-2 automatic
kickdown through anxiously stepping on the accelerator pedal to the end. The engine brake can be used for the 3rd
speed.

State of 4th speed

The combination instrument displays the state of 4th speed, be capable of realizing 4-3 or 4-2 automatic kickdown
through anxiously stepping on the accelerator pedal to the end. The engine brake can be used for 4th speed.

State of 5th speed

The combination instrument displays the state of 5th speed. Be capable of realizing 5-4 or 5-3 automatic
kickdown through anxiously stepping on the accelerator pedal to the end. The engine brake can be used for 5th
speed.

1247

State of 6th speed

The combination instrument displays the state of 6th speed. Be capable of realizing 6-5 or 6-4 automatic
kickdown through anxiously stepping on the accelerator pedal to the end. The engine brake can be used for 6th
speed.
