Your vehicle is designed to operate on
regular unleaded gasoline with a minimum
pump (R+M)/2 octane rating of 87 or
regular unleaded gasoline blended with a
maximum of 85% ethanol (E85).
Some fuel stations, particularly those in
high altitude areas, offer fuels posted as
regular unleaded gasoline with an octane
rating below 87. The use of these fuels
could result in engine damage that will not
be covered by the vehicle warranty.
For best overall vehicle and engine
performance, premium fuel with an octane
rating of 91 or higher is recommended. The
performance gained by using premium fuel
is most noticeable in hot weather as well
as other conditions, for example when
towing a trailer. See Towing (page 288).
Do not be concerned if the engine
sometimes knocks lightly. However, if the
engine knocks heavily while using fuel with
the recommended octane rating, contact
an authorized dealer to prevent any engine
damage.
We recommend Top Tier detergent
gasolines, where available to help minimize
engine deposits and maintain optimal
vehicle and engine performance. For
additional information, refer to
www.toptiergas.com.
Note: Use of any fuel for which the vehicle
was not designed can impair the emission
control system, cause loss of vehicle
performance, and cause damage to the
engine which may not be covered by the
vehicle Warranty. Do not use:
•
Diesel fuel.
• Fuels containing kerosene or paraffin.
• Fuels containing more than 85%
ethanol or E100 fuel.
• Fuels containing methanol.
• Fuels containing metallic-based
additives, including manganese-based
compounds.
• Fuels containing the octane booster
additive, methylcyclopentadienyl
manganese tricarbonyl (MMT).
• Leaded fuel, using leaded fuel is
prohibited by law.
The use of fuels with metallic compounds
such as methylcyclopentadienyl
manganese tricarbonyl (commonly known
as MMT), which is a manganese-based
fuel additive, will impair engine
performance and affect the emission
control system.
Switching Between E85 and
Gasoline
We do not recommend repeatedly
alternating between E85 and gasoline. If
you switch from using E85 to gasoline, or
from gasoline to E85, add as much fuel as
possible, at least half a tank. Drive your
vehicle immediately for a minimum of 5 mi
(8 km)
to allow it to adapt to the change
in ethanol concentration. If you use E85
exclusively, we recommend that you fill
the fuel tank with regular unleaded
gasoline at each scheduled oil change.

EMISSION LAW
WARNING: Do not remove or alter
the original equipment floor covering or
insulation between it and the metal floor
of the vehicle. The floor covering and
insulation protect occupants of the
vehicle from the engine and exhaust
system heat and noise. On vehicles with
no original equipment floor covering
insulation, do not carry passengers in a
manner that permits prolonged skin
contact with the metal floor. Failure to
follow these instructions may result in
fire or personal injury.
U.S. federal laws and certain state laws
prohibit removing or rendering inoperative
emission control system components.
Similar federal or provincial laws may
apply in Canada. We do not approve of any
vehicle modification without first
determining applicable laws. Tampering with emissions
control systems including
related sensors or the Diesel
Exhaust Fluid system can result in reduced
engine power and the illumination of the
service engine soon light. Tampering With a Noise Control
System
Federal laws prohibit the following acts:
•
Removal or rendering inoperative by
any person other than for purposes of
maintenance.
• Repair or replacement of any device or
element of the design incorporated into
a new vehicle for the purpose of noise
control prior to its sale or delivery to
the ultimate purchaser or while it is in
use.
• The use of the vehicle after any person
removes or renders inoperative any
device or element of the design.
The U.S. Environmental Protection Agency
may presume to constitute tampering as
follows:
• Removal of hood blanket, fender apron
absorbers, fender apron barriers,
underbody noise shields or acoustically
absorptive material.
• Tampering or rendering inoperative the
engine speed governor, to allow engine
speed to exceed manufacturer
specifications.
If the engine does not start, runs rough,
experiences a decrease in engine
performance, experiences excess fuel
consumption or produces excessive
exhaust smoke, check for the following:
• A plugged or disconnected air inlet
system hose.
• A plugged engine air filter element.
• Water in the fuel filter and water
separator.
• A clogged fuel filter.
• Contaminated fuel.
• Air in the fuel system, due to loose
connections.
• An open or pinched sensor hose.
• Incorrect engine oil level.
