CAUTION!
Using a transmission fluid other than the manufac-
turer ’s recommended fluid may cause deterioration
in transmission shift quality. Refer to “Fluids, Lubri-
cants, and Genuine Parts” in this section for fluid
specifications.
Special Additives
The manufacturer strongly recommends against using
any special additives in the transmission.
Transmission fluid is an engineered product and its
performance may be impaired by supplemental addi-
tives. Therefore, do not add any fluid additives to the
transmission. The only exception to this policy is the use
of special dyes for diagnosing fluid leaks.
CAUTION!
Do not use chemical flushes in your transmission as
the chemicals can damage your transmission compo-
nents. Such damage is not covered by the New
Vehicle Limited Warranty.
Fluid Level Check
The fluid level is preset at the factory and does not
require adjustment under normal operating conditions.
Routine fluid level checks are not required, therefore the
transmission has no dipstick. Your authorized dealer can
check your transmission fluid level using special service
tools. If you notice fluid leakage or transmission malfunc-
tion, visit your authorized dealer immediately to have
the transmission fluid level checked. Operating the ve-
hicle with an improper fluid level can cause severe
transmission damage.

MAINTAINING YOUR VEHICLE 297
MAINTENANCE SCHEDULE
Your vehicle is equipped with an automatic oil change
indicator system. The oil change indicator system will
remind you that it is time to take your vehicle in for
scheduled maintenance.
Based on engine operation conditions, the oil change
indicator message will illuminate in the instrument clus-
ter. This means that an engine oil and engine oil filter
change is required for your vehicle. Operating conditions
such as frequent short-trips, trailer tow, extremely hot or
cold ambient temperatures, and E85 fuel usage will
influence when the “Change Oil” or “Oil Change Re-
quired” message is displayed. Severe Operating Condi-
tions can cause the change oil message to illuminate as
early as 3,500 miles (5,600 km) since last reset. Have your
vehicle serviced as soon as possible, within the next 500
miles (805 km).The Wrench Warning Light may appear in the cluster as
a service reminder when vehicle maintenance is required,
according to the scheduled maintenance mileage. The
maintenance schedule intervals are set by the manufac-
turer. Failure to have them carried out may void your
New Vehicle Limited Warranty.
NOTE:
Under no circumstances should oil change inter-
vals exceed 10,000 miles (16,000 km), twelve months or
350 hours of engine run time, whichever comes first. The
350 hours of engine run or idle time is generally only a
concern for fleet customers.

conditions, including:

• On dusty roads
