PERIODIC SAFETY CHECKS YOU SHOULD
M
AKE OUTSIDE THE VEHICLE
Tires
Examine tires for excessive tread wear and uneven
wear patterns. Check for stones, nails, glass, or
other objects lodged in the tread or sidewall.
Inspect the tread for cuts and cracks. Inspect
sidewalls for cuts, cracks, and bulges. Check the
lug nuts/bolt torque for tightness. Check the tires
(including spare) for proper cold inflation pressure.
Lights
Have someone observe the operation of brake
lights and exterior lights while you work the
controls. Check turn signal and high beam
indicator lights on the instrument panel.
Door Latches
Check for proper closing, latching, and locking.
Fluid Leaks
Check area under the vehicle after overnight
parking for fuel, coolant, oil, or other fluid leaks.
Also, if gasoline fumes are detected or if fuel or
brake fluid leaks are suspected, the cause should
be located and corrected immediately.
EXHAUST GAS The best protection against carbon monoxide entry
into the vehicle body is a properly maintained
engine exhaust system.
Whenever a change is noticed in the sound of the
exhaust system, when exhaust fumes can be
detected inside the vehicle, or when the underside
or rear of the vehicle is damaged, have an
authorized dealer inspect the complete exhaust
system and adjacent body areas for broken,
damaged, deteriorated, or mispositioned parts.
Open seams or loose connections could permit
exhaust fumes to seep into the passenger
compartment. In addition, inspect the exhaust
system each time the vehicle is raised for
lubrication or oil change. Replace as required.
WARNING!
Exhaust gases can injure or kill. They contain
carbon monoxide (CO), which is colorless and
odorless. Breathing it can make you
unconscious and can eventually poison you. To
avoid breathing (CO), follow these safety tips:
Do not run the engine in a closed garage or in
confined areas any longer than needed to
move your vehicle in or out of the area.
If you are required to drive with the trunk/lift -
gate/rear doors open, make sure that all
windows are closed and the climate control
BLOWER switch is set at high speed. DO NOT
use the recirculation mode.
If it is necessary to sit in a parked vehicle with
the engine running, adjust your heating or
cooling controls to force outside air into the
vehicle. Set the blower at high speed.

SERVICING AND MAINTENANCE
SCHEDULED SERVICING — GASOLINE
ENGINE
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 will influence when the “Oil Change
Required” message is displayed. Have your vehicle
serviced as soon as possible, within the next
500 miles (805 km).An authorized dealer will reset the oil change
indicator message after completing the scheduled
oil change. If a scheduled oil change is performed
by someone other than an authorized dealer, the
message can be reset by referring to the steps
described under Instrument Cluster Display
Ú
page 81.
Under no circumstances should oil change
intervals exceed 8,000 miles (13,000 km),
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. Once A Month Or Before A Long Trip:
Check engine oil level.
Check windshield washer fluid level.
Check the tire inflation pressures and look for
unusual wear or damage. Rotate at the first sign
of irregular wear.
Check the fluid levels of the coolant reservoir,
brake master cylinder, power steering and auto
-
matic transmission (6-speed only), and fill as
needed.
Check function of all interior and exterior lights.

MAINTENANCE PLAN – GASOLINE ENGINE
Refer to the maintenance plan on the following pages for required maintenance. More frequent maintenance may be needed in severe conditions, such as dusty
areas and very short trip driving. In some extreme conditions, additional maintenance not specified in the maintenance schedule may be required.
NOTE:Using white lithium grease, lubricate the door hinge pivot joints twice a year to prevent premature wear.
At Every Oil Change Interval As Indicated By Oil Change Indicator System:
Change oil and filter.
Rotate the tires. Rotate at the first sign of irregular wear, even if it occurs before the oil indicator system turns on.
Inspect engine cooling system protection and hoses.
Inspect exhaust system.
Inspect engine air cleaner filter if using in dusty or off-road conditions. Replace the engine air cleaner filter, if necessary.
Inspect battery and clean and tighten terminals as required.
Inspect the CV/Universal joints.
Inspect automatic transmission fluid if equipped with dipstick.
Inspect brake pads, shoes, rotors, drums, hoses and parking brake.
Inspect front end, and lubricate — If equipped with serviceable fittings.
Inspect and replace the Evaporative System Fresh Air Filter as necessary, replacement may be more frequent if vehicle is operated in extreme dusty condi-
tions.8

OIL CHANGE INDICATOR SYSTEM —
D
IESEL ENGINE
Your vehicle is equipped with an engine oil change
indicator system. This system will alert you when it
is time to change your engine oil by displaying the
words “Oil Change Due” in your instrument cluster
display. The engine oil change indicator system is
duty cycle based, which means the engine oil
change interval may fluctuate depending on your
personal driving style. Failure to change the engine
oil per the maintenance schedule can result in
internal engine damage.
An authorized dealer will reset the oil change
indicator message after completing the scheduled
oil change. If a scheduled oil change is performed
by someone other than an authorized dealer, the
message can be reset by referring to the steps
described under Instrument Cluster Display
Ú page 81.
Replace the engine oil and oil filter every
15,000 miles (24,000 km) or 12 months, or
sooner if prompted by the oil change indicator
system. Under no circumstances should oil change
intervals exceed 15,000 miles (24,000 km) or 12 months, whichever comes first.CAUTION!
Failure to perform the required maintenance
items may result in damage to the vehicle.

22_DPF_OM_EN_USC_t.book Page 332

SERVICING AND MAINTENANCE333
NOTE:
Under no circumstances should oil change inter -
vals exceed 15,000 miles (24,000 km) or
12 months or 500 hours, whichever comes first.
It is recommended that every 3,000 miles
(4,800 km), check the engine oil level at least
30 minutes after a fully warmed engine is shut
off. Checking the oil level while the vehicle is on
level ground will improve the accuracy of the oil
level reading. Add oil only when the level is at or
below the ADD or MIN mark.
Severe service (high ambient temperature,
short trips, heavy loading, trailer towing,
off-road, or law enforcement use) may reduce
oil change intervals. If models configured with optional B20 capability
are operated with greater than 5% levels of
biodiesel, the oil change interval must not exceed
12,500 miles (20,000 km) or 400 hours,
whichever comes first under any circumstances.
See the Fuel Requirements section for more
information regarding operation with biodiesel
blend (B6-B20) fuel meeting ASTM specification
D-7467.
PERFORM SERVICE INDICATOR —
D
IESEL ENGINE
Your vehicle will require emissions maintenance at
a set interval. To help remind you when this
maintenance is due, the instrument cluster will
display “Perform Service”. When the “Perform
Service” message is displayed on the instrument
cluster it is necessary to have the emissions
maintenance performed. Emissions maintenance
may include replacing the Closed Crankcase
Ventilation (CCV) filter element. The procedure for
clearing and resetting the “Perform Service”
indicator message is located in the appropriate
Service Information.
