MAINTENANCE
OPERATION

*

Refer to Vehicle Emission Control Information for Spark Plug and Gap Specifications.

*2 At 60,000 miles (96 000 km), your dealer will replace the PCV valve at no cost, 

except California vehicles

.

*3 If vehicle is registered in California, the California Air Resources Board has determined that the failure to perform this maintenance item will not nullify the emission

warranty or limit recall liability prior to the completion of the vehicle’s useful life. We, however, urge that all recommended maintenance services be performed at
the indicated intervals and the maintenance be recorded.

Rear axles are lubricated for life. These lubricants are not to be checked or changed unless a leak is suspected, service is required, or the axle assembly has
been submerged in water. The axle lubricant should be changed anytime the axle has been submerged in water. For police and taxi applications, replace rear
axle lubricant every 100,000 miles (160,000 km). Rear axle lubricant change may be waived if the axle was filled with 75W140 synthetic gear lubricant. Add
four ounces of additive friction modifier or equivalent for complete refill of Traction-Lok rear axles.
