05 02.25 Rear differential lock system CAUTION Do not use the rear differential lock in the conditions other than above. Large steering effort and careful cornering control will be required. LS17011 LS17013 The rear differential lock system is provided for use only when wheel spinning occurs in a ditch or on a slippery or ragged surface. This differential lock system is effective in case one of the rear wheels is spinning. Four- wheel drive models- Before using the rear differential lock system, first shift the four- wheel drive control into "L4" to see if this is sufficient. If this has no effect, additionally use the rear differential lock system. To lock the rear differential, push the switch. Be sure to stop the wheels before locking the differential. For easy locking, depress the clutch pedal, push the lock switch and slowly release the clutch pedal. The indicator light will blink when the switch is turned on. Wait a few seconds for the system to complete operation. After the differential is locked, the light will stop blinking and remain on. 2005 TACOMA from Mar. '05 Prod. (OM35862U) 185
