MS-6395. Refer to your engine oil filler cap for correct SAE grade. SAE 5W-30 engine oil ap-
proved to MB 229.31 or MB 229.51 may be used when SAE 5W-20 engine oil is not available.
Engine Oil – ACEA Categories
(5.7L Engine) For countries that use the ACEA European Oil Categories for Service Fill Oils, use engine oils
meeting the requirements of ACEA C3, and approved to MB 229.31 or MB 229.51. SAE 5W-30

Spark Plugs – 5.7L Engine LZFR5C–11G (Gap 0.043 in [1.1 mm])
Fuel Selection – 3.6L Engine 91 Octane
Fuel Selection – 5.7L Engine 91 Octane Acceptable - 95 Octane Recommended
Fuel Selection – 3.0L Diesel Engine Use good quality diesel fuel from a reputable supplier in your vehicle. The manufacturer requires
that you must fuel this vehicle with Ultra Low Sulfur Highway Diesel fuel (15 ppm Sulfur maximum)
and prohibits the use of Low Sulfur Highway Diesel fuel (500 ppm Sulfur maximum) to avoid dam-
age to the emissions control system. For most year-round service, No. 2 diesel fuel meeting ASTM
specification D-975 Grade S15 will provide good performance. If the vehicle is exposed to extreme
cold (below 20F or -7C), or is required to operate at colder-than-normal conditions for prolonged
periods, use climatized No. 2 diesel fuel or dilute the No. 2 diesel fuel with 50% No. 1 diesel fuel.
This will provide better protection from fuel gelling or wax-plugging of the fuel filters. This vehicle is
fully compatible with biodiesel blends up to 5% biodiesel meeting ASTM specification D-975.

MAINTENANCE SCHEDULE
Maintenance Schedule – Gasoline
Engine
The Scheduled Maintenance services listed in
this manual must be done at the times or
mileages specified to protect your vehicle war-
ranty and ensure the best vehicle performance
and reliability. More frequent maintenance may
be needed for vehicles in severe operating
conditions, such as dusty areas and very short
trip driving. Inspection and service should also
be done anytime a malfunction is suspected.
The oil change indicator system will remind you
that it is time to take your vehicle in for sched-
uled maintenance.
On Electronic Vehicle Information Center
(EVIC) equipped vehicles “Oil Change Re-quired” will be displayed in the EVIC and a
single chime will sound, indicating that an oil
change is necessary.
The oil change indicator message will illumi-
nate approximately 7,000 miles (11 200 km)
after the most recent oil change was per-
formed. Have your vehicle serviced as soon as
possible, within 500 miles (800 km).
NOTE:
•
The oil change indicator message will not
monitor the time since the last oil change.
Change your vehicles oil if it has been
6 months since your last oil change even
if the oil change indicator message is
NOT illuminated.
• Change your engine oil more often if you
drive your vehicle off-road for an ex-
tended period of time. •
Under no circumstances should oil
change intervals exceed 7,500 miles
(12 000 km) or 6 months, whichever
comes first.
Your authorized dealer will reset the oil change
indicator message after completing the sched-
uled oil change. If this scheduled oil change is
performed by someone other than your autho-
rized dealer the message can be reset by
referring to the steps described under ”Elec-
tronic Vehicle Information Center” in “Under-
standing Your Instrument Panel” for further in-
formation.

At Each Stop for Fuel
•Check the engine oil level about 5 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.
• Check the windshield washer solvent and
add if required. Once a Month
•
Check tire pressure and look for unusual
wear or damage.
• Inspect the battery and clean and tighten the
terminals as required.
• Check the fluid levels of the coolant reser-
voir, brake master cylinder, power steering
and transmission (5.7L only) and add as
needed.
• Check all lights and other electrical items for
correct operation. At Each Oil Change
•
Change the engine oil filter.
• Inspect the brake hoses and lines.
CAUTION!
Failure to perform the required maintenance
items may result in damage to the vehicle.
