TRANSFER CASE VERIFICATION TEST

To select or deselect 2WD, AWD or 4HI mode, vehicle speed must be below 88 Kmh (55 mph) with all wheels at vehicle speed.
Shifts will not take place with a wheel speed difference of greater than 21 Kmh (13 mph) between the front and rear wheels.
To select or deselect 4LO (if equipped), vehicle speed must be below 5 Kmh (3 mph) with the ignition ON and the transmission in neutral (auto trans) or the clutch pedal pressed (man trans).
To select or deselect Transfer Case Neutral, vehicle speed must be 0 Kmh (0 mph) with the ignition ON, engine OFF, the brake pedal applied, and the transmission in neutral (auto trans) or the clutch pedal pressed (man trans). Press the Neutral button (if equipped) on the Transfer Case Selector Switch until the Neutral Indicator is illuminated.
WARNING: Apply the parking brake. The vehicle may roll with the Transfer Case in neutral.
To verify that the Transfer Case is in Neutral, shift the automatic transmission into reverse and release the brake pedal for three seconds or shift the manual transmission into gear and slowly release the clutch pedal. There should be no vehicle movement if the Transfer Case is in Neutral.
