Fuel Selection
Use good quality diesel fuel from a reputable supplier in
your vehicle. Federal law 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
damage 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. We rec-
ommend you use a blend of up to 5% biodiesel, meeting
ASTM specification D-975 with your diesel engine.
This
vehicle is compatible with biodiesel blends greater than 5%
but no greater than 20% biodiesel meeting ASTM specification
D-7467 provided the shortened maintenance intervals are
followed as directed.
Diesel Exhaust Fluid
MOPAR Diesel Exhaust Fluid (API Certified) (DEF) or
equivalent that has been API Certified to the ISO
22241 standard. Use of fluids not API Certified to ISO
22241 may result in system damage.
NOTE:
If climatized or diesel Number 1 ULSD fuel is not available, and you are operating
below (20°F/-6°C), in sustained arctic conditions, Mopar Premium Diesel Fuel
Treatment (or equivalent) is recommended to avoid gelling.
CAUTION!
• Mixing of engine coolant (antifreeze) other than specified Organic Additive
Technology (OAT) engine coolant (antifreeze), may result in engine damage and
may decrease corrosion protection. Organic Additive Technology (OAT) engine
coolant is different and should not be mixed with Hybrid Organic Additive
Technology (HOAT) engine coolant (antifreeze) or any “globally compatible”
coolant (antifreeze). If a non-OAT engine coolant (antifreeze) is introduced into
the cooling system in an emergency, the cooling system will need to be drained,
flushed, and refilled with fresh OAT coolant (conforming to MS.90032), by an
authorized dealer as soon as possible.
• Do not use water alone or alcohol-based engine coolant (antifreeze) products. Do
not use additional rust inhibitors or antirust products, as they may not be
compatible with the radiator engine coolant and may plug the radiator.
• This vehicle has not been designed for use with propylene glycol-based engine
coolant (antifreeze). Use of propylene glycol-based engine coolant (antifreeze)
is not recommended.
