pushed.
NOTE:

Conventional (fixed speed) cruise control mode is automatically turned off when the driving speed lowers
to 20 MPH (32 km/h for CANADA models) due to the deceleration of the vehicle ahead.

The lowest set speed is 25 MPH (40 km/h for CANADA models).
Check For The Cancellation Of Conventional (Fixed Speed) Cruise Control Mode (Normal
Driving Condition) In The Following Cases:
Refer.toACS-9, "Check For The Cancellation Of Vehicle-To-Vehicle Distance Control Mode (Normal Driving
Condition) In The Following Cases:"
Check For Restoring The Speed That Is Set By Conventional (Fixed Speed) Cruise Control
Mode Before ICC Cancellation
Refer to.ACS-9, "Check For Restoring The Speed That Is Set By Vehicle-To-Vehicle Distance Control Mode
Before Cancellation"

make sure selector lever can be shifted from “P” position only when brake pedal is depressed.
3. Move the selector lever and check for excessive effort, sticking, noise or rattle.
4. Confirm the selector lever stops at each position with the feel of engagement when it is moved through all
the positions. Check whether or not the actual position the selector lever is in matches the position shown
by the shift position indicator and the transmission body.
5. The method of operating the lever to individual positions cor-
rectly should be as shown in the figure.
6. When selector button is pressed in “P”, “R”, or “N” position with-
out applying forward/backward force to selector lever, check but-
ton operation for sticking.

A/T SHIFT LOCK SYSTEMPFP:34950
DescriptionACS002RT

The mechanical key interlock mechanism also operates as a shift lock:
With the ignition switch turned to ON, the selector lever cannot be shifted from “P” position to any other
position unless the brake pedal is depressed.
With the key removed, the selector lever cannot be shifted from “P” position to any other position.
The key cannot be removed unless the selector lever is placed in “P” position.

The shift lock and key interlock mechanisms are controlled by the ON-OFF operation of the shift lock sole-
noid and by the operation of the rotator and slider located inside the key cylinder.
