SERVICING AND MAINTENANCE
SC\b\fED SERVICING
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. This
means that service 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 “Oil Change Required”
message is displayed. Severe operating
conditions can cause the change oil message to
illuminate as early as 3,500 miles (5,600 kmyf since last reset. Have your vehicle serviced as
soon as possible, within the next 500 miles
(805 kmyf. An authorized dealer will reset the oil change
indicator message after completing the
scheduled oil change.
NOTE:
Under no circumstances should oil change
intervals exceed 10,000 miles (16,000 kmyf
12 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.
Severe Duty All Models
Vehicles that are operated in a dusty and
off-road environment, or predominately at idle
or very low engine RPM are known as Severe
Duty vehicles. It is recommended that you
change engine oil at 4,000 miles (6,500 kmyfRU
350 hours of engine run time.
Once A Month Or Before A Long Trip:Check engine oil level
Check windshield washer fluid level
Check the tire pressures and look for unusual
wear or damage
Check the fluid levels of the coolant reservoir,
brake master cylinder and fill as needed
Check function of all interior and exterior
lights

fluid can severely damage your brake
system and/or impair its performance. The
proper type of brake fluid for your vehicle is
also identified on the original factory
installed hydraulic master cylinder reser -

NOTE:
It is illegal to remove or alter the VIN.
BRAKE SYSTEM
Your vehicle is equipped with dual hydraulic
brake systems. If either of the two hydraulic
systems loses normal capability, the remaining
system will still function. However, there will be some loss of overall braking effectiveness. You
may notice increased pedal travel during
application, greater pedal force required to slow
or stop, and potential activation of the Brake
Warning Light.
In the event power assist is lost for any reason
(i.e., repeated brake applications with the
engine offyfWKHEUDNHVZLOOVWLOOIXQFWLRQ
However, the effort required to brake the
vehicle will be much greater than that required
with the power system operating.
W\b\f AND TIRE TORQUE SPECIFICATIONS
Proper lug nut/bolt torque is very important to
ensure that the wheel is properly mounted to
the vehicle. Any time a wheel has been removed
and reinstalled on the vehicle, the lug nuts/
bolts should be torqued using a properly
calibrated torque wrench using a six sided (hexyf
deep wall socket.
TORQUE SPECIFICATIONS
**Use only authorized dealer recommended lug nuts/
bolts and clean or remove any dirt or oil before tightening.
Inspect the wheel mounting surface prior to
mounting the tire and remove any corrosion or
loose particles.

Wheel Mounting Surface

Tighten the lug nuts/bolts in a star pattern until
each nut/bolt has been tightened twice. Ensure
that the socket is fully engaged on the lug nut/
bolt (do not insert it half wayyf.
