Interaxle Lock Operation
Notice: Engage the interaxle lock only when the vehicle is moving at less than 30 mph (48 km/h). Engaging the interaxle lock at speeds above 30 mph (48 km/h) can cause axle damage.
An interaxle lock should not be engaged on a vehicle with obviously spinning wheels. Engagement at high speed or power can damage the axle(s).
Important: If equipped with the optional automatic disengagment feature, the interaxle lock will not engage above 30 mph speed (48 km/h) and will automatically disengage at 50 mph (79 km/h). The parameters of this feature are not modifiable.
Note: If the interaxle lock is engaged when the engine is turned off, the interaxle lock will disengage.
- With the engine running, toggle up on the interaxle lock switch to engage the interaxle lock. Do not wait until traction is lost and the tires are spinning before engaging the interaxle lock.
- If the vehicle is moving, briefly let up on the accelerator until the interaxle lock engages. The indicator light on the interaxle lock switch will illuminate red when the lock is engaged. Depending on the vehicle configuration, a buzzer may also sound.
- Proceed over poor road conditions with caution.
- Toggle down on the interaxle lock switch to disengage the interaxle lock after leaving poor road conditions.
- If the vehicle is moving, briefly let up on the accelerator to allow the interaxle lock to disengage, then resume driving at normal speed. Once the interaxle lock disengages, the indicator light in both the switch and on the ICU display screen will turn off.
Notice: Do not operate the vehicle continuously with the interaxle locked during extended good road conditions. To do so could result in damage to the axle gearing and excessive driveline and tire wear.
Note: Both the switch light and inter-axle indicators on the screen will flash if there is a delay in engaging or disengaging the locks.
