Dodge Dakota (2011 year). Instruction — part 19

The “Tire Pressure Monitoring Telltale Light” will flash on
and off for 75 seconds, and remain on solid when a system
fault is detected. The system fault will also sound a chime.
If the ignition key is cycled, this sequence will repeat,
providing the system fault still exists. The “Tire Pressure
Monitoring Telltale Light” will turn off when the fault
condition no longer exists. A system fault can occur by any
of the following scenarios: 1) Jamming due to electronic
devices or driving next to facilities emitting the same radio
frequencies as the TPM sensors; 2) Installing some form of
aftermarket window tinting that affects radio wave sig-
nals; 3) Lots of snow or ice around the wheels or wheel
housings; 4) Using tire chains on the vehicle; 5) Using
wheels/tires not equipped with TPM sensors.

NOTE: Your vehicle is equipped with a non-matching
full size spare wheel and tire assembly.

1. This spare tire does not have a tire pressure monitor-
ing sensor. Therefore, the TPMS will not monitor the tire
pressure in the spare tire.

2. If you install the full size spare tire in place of a road
tire that has a pressure below the low-pressure warning
limit, upon the next ignition key cycle a chime will sound
and the “TPM Telltale Light” will still turn ON due to the
low tire.

3. However, after driving the vehicle for up to 20 min-
utes above 15 mph (24 km/h), the “TPM Telltale Light”
will flash on and off for 75 seconds and then remain on
solid.

4. For each subsequent ignition key cycle, a chime will
sound and the “TPM Telltale Light” will flash on and off
for 75 seconds and then remain on solid.

5. Once you repair or replace the original road tire, and
reinstall it on the vehicle in place of the full size spare tire,
the TPMS will update automatically and the “TPM
Telltale Light” will turn OFF, as long as no tire pressure is
below the low-pressure warning limit in any of the four

active road tires. The vehicle may need to be driven for
up to 20 minutes above 15 mph (24 km/h) in order for the
TPMS to receive this information.

FUEL REQUIREMENTS

These engines are designed to meet all
emissions regulations, and provide excel-
lent fuel economy and performance when
using high quality unleaded “regular”
gasoline having an octane rating of 87. The
use of premium gasoline is not recom-

mended, as it will not provide any benefit over regular
gasoline in these engines.

Light spark knock at low engine speeds is not harmful to
your engine. However, continued heavy spark knock at
high speeds can cause damage and immediate service is
required. Poor quality gasoline can cause problems such
as hard starting, stalling, and hesitations. If you experi-
ence these symptoms, try another brand of gasoline
before considering service for the vehicle.

5

STARTING AND OPERATING

301

Over 40 auto manufacturers worldwide, have issued and
endorsed consistent gasoline specifications (the World-
wide Fuel Charter, WWFC), which define fuel properties
necessary to deliver enhanced emissions, performance,
and durability for your vehicle. The manufacturer recom-
mends the use of gasoline that meets the WWFC speci-
fications, if they are available.

Reformulated Gasoline
Many areas of the country require the use of cleaner
burning gasoline, referred to as “Reformulated Gaso-
line.” Reformulated gasolines contain oxygenates, and
are specifically blended to reduce vehicle emissions and
improve air quality.

The manufacturer supports the use of reformulated gaso-
lines. Properly-blended reformulated gasolines will pro-
vide excellent performance and durability of engine and
fuel system components.

Gasoline/Oxygenate Blends
Some fuel suppliers blend unleaded gasoline with oxy-
genates such as Ethanol. Fuels blended with oxygenates
may be used in your vehicle.

CAUTION!

DO NOT use gasoline containing Methanol or gaso-
line containing more than 10% Ethanol. Use of these
blends may result in starting and driveability prob-
lems and may damage critical fuel system compo-
nents.

Problems that result from using methanol/gasoline or
E-85 Ethanol blends are not the responsibility of the
manufacturer.

302

STARTING AND OPERATING

E-85 Usage In Non-Flex Fuel Vehicles
Non-FFV vehicles are compatible with gasoline contain-
ing 10% ethanol (E10). Gasoline with higher ethanol
content may void the vehicle’s warranty.

If a Non-FFV vehicle is inadvertently fueled with E-85
fuel, the engine will have some or all of these symptoms:

• operate in a lean mode
• OBD II “Malfunction Indicator Light” on
• poor engine performance
• poor cold start and cold drivability
• increased risk for fuel system component corrosion

To fix a Non-FFV vehicle inadvertently fueled once with
E-85 perform the following:

• drain the fuel tank (see your authorized dealer)
• change the engine oil and oil filter

• disconnect and reconnect the battery to reset the

engine controller memory

More extensive repairs will be required for prolonged
exposure to E-85 fuel.

MMT In Gasoline
MMT is a manganese containing metallic additive that is
blended into some gasoline to increase octane. Gasoline
blended with MMT provides no performance advantage
beyond gasoline of the same octane number without
MMT. Gasoline blended with MMT reduces spark plug
life and reduces emission system performance in some
vehicles. The manufacturer recommends that gasoline
without MMT be used in your vehicle. The MMT content
of gasoline may not be indicated on the gasoline pump,
therefore, you should ask your gasoline retailer whether
gasoline contains MMT. It is even more important to look
for gasolines without MMT in Canada, because MMT can

5

STARTING AND OPERATING

303

be used at levels higher than those allowed in the United
States. MMT is prohibited in Federal and California
reformulated gasoline.

Materials Added To Fuel
All gasolines sold in the United States are required to
contain effective detergent additives. Use of additional
detergents or other additives is not needed under normal
conditions and would result in unnecessary cost. There-
fore, you should not have to add anything to the fuel.

Fuel System Cautions

CAUTION!

Follow these guidelines to maintain your vehicle’s
performance:

(Continued)

CAUTION! (Continued)

• The use of leaded gas is prohibited by Federal law.

Using leaded gasoline can impair engine perfor-
mance, damage the emission control system.

• An out-of-tune engine, or certain fuel or ignition

malfunctions, can cause the catalytic converter to
overheat. If you notice a pungent burning odor or
some light smoke, your engine may be out of tune
or malfunctioning and may require immediate
service. Contact your authorized dealer for service
assistance.

• When pulling a heavy load or driving a fully

loaded vehicle when the humidity is low and the
temperature is high, use a premium unleaded fuel
to help prevent spark knock. If spark knock per-
sists, lighten the load, or engine piston damage
may result.

(Continued)

304

STARTING AND OPERATING

CAUTION! (Continued)

• The use of fuel additives which are now being

sold as octane enhancers is not recommended.
Many of these products contain high concentra-
tions of methanol. Fuel system damage or vehicle
performance problems resulting from the use of
such fuels or additives is not the responsibility of
the manufacturer.

NOTE:

Intentional tampering with emissions control

systems can result in civil penalties being assessed
against you.

Carbon Monoxide Warnings

WARNING!

Carbon monoxide (CO) in exhaust gases is deadly.
Follow the precautions below to prevent carbon
monoxide poisoning:
• Do not inhale exhaust gases. They contain carbon

monoxide, a colorless and odorless gas, which can
kill. Never run the engine in a closed area, such as
a garage, and never sit in a parked vehicle with the
engine running for an extended period. If the
vehicle is stopped in an open area with the engine
running for more than a short period, adjust the
ventilation system to force fresh, outside air into
the vehicle.

(Continued)

5

STARTING AND OPERATING

305

WARNING! (Continued)

• Guard against carbon monoxide with proper

maintenance. Have the exhaust system inspected
every time the vehicle is raised. Have any abnor-
mal conditions repaired promptly. Until repaired,
drive with all side windows fully open.

FLEXIBLE FUEL (4.7L ENGINE ONLY) —
IF EQUIPPED

E-85 General Information
The information in this section is for Flexible Fuel ve-
hicles only. These vehicles can be identified by a unique
fuel filler door label that states Ethanol (E-85) or Un-
leaded Gasoline Only.

This section only covers those

subjects that are unique to these vehicles. Please refer to
the other sections of this instruction for information on
features that are common between Flexible Fuel and
gasoline-only powered vehicles.

CAUTION!

Only vehicles with the E-85 fuel filler door label can
operate on E-85.

E-85 Fuel Cap

306

STARTING AND OPERATING

Ethanol Fuel (E-85)
E-85 is a mixture of approximately 85% fuel ethanol and
15% unleaded gasoline.

WARNING!

Ethanol vapors are extremely flammable and could
cause serious personal injury. Never have any smok-
ing materials lit in or near the vehicle when remov-
ing the fuel filler tube cap (gas cap) or filling the
tank. Do not use E-85 as a cleaning agent and never
use it near an open flame.

Fuel Requirements
Your vehicle will operate on both unleaded gasoline with
an octane rating of 87, or E-85 fuel, or any mixture of
these two. For best results, a refueling pattern that
alternates between E-85 and unleaded gasoline should be
avoided.

When you do switch fuel types it is recommended that:

• you do not switch when the fuel gauge indicates less

than 1/4 full

E-85 Badge

5

STARTING AND OPERATING

307

• you do not add less than 5 gallons (19 Liters) when

refueling

• you operate the vehicle immediately after refueling for

a period of at least 5 minutes

Observing these precautions will avoid possible hard
starting and/or significant deterioration in driveability
during warm up.

NOTE:

• When the ambient temperature is above 90° F (32° C),

you may experience hard starting and rough idle
following start up even if the above recommendations
are followed.

• Some additives used in regular gasoline are not fully

compatible with E-85 and may form deposits in your
engine. To eliminate driveability issues that may be
caused by these deposits, a supplemental gasoline
additive, such as MOPAR

威 Injector Cleanup or

Techron may be used.

Selection Of Engine Oil For Flexible Fuel Vehicles
(E-85) and Gasoline Vehicles
FFV vehicles operated on E-85 require specially formu-
lated engine oils. These special requirements are included
in MOPAR

威 engine oils, and in equivalent oils meeting

Chrysler Specification MS-6395. The manufacturer re-
quires engine oils that are API Certified and meet the
requirements of Material Standard MS-6395. MS-6395
contains additional requirements, developed during ex-
tensive fleet testing, to provide additional protection to
Chrysler Group LLC engines. Use MOPAR

威 or an

equivalent oil meeting the specification MS-6395.

Starting
The characteristics of E-85 fuel make it unsuitable for use
when ambient temperatures fall below 0°F (-18°C). In the
range of 0°F (-18°C) to 32°F (0°C), you may experience an
increase in the time it takes for your engine to start, and
a deterioration in driveability (sags and/or hesitations)
until the engine is fully warmed up.

308

STARTING AND OPERATING

NOTE:

Use of the engine block heater (if equipped) is

beneficial for E-85 startability when the ambient tempera-
ture is less than 32°F (0°C).

Cruising Range
Because E-85 fuel contains less energy per gallon/liter
than gasoline, you will experience an increase in fuel
consumption. You can expect your miles per gallon
(mpg)/miles per liter and your driving range to decrease
by about 30%, compared to gasoline operation.

Replacement Parts
Many components in your Flexible Fuel Vehicle (FFV) are
designed to be compatible with ethanol. Always be sure
that your vehicle is serviced with correct ethanol com-
patible parts.

CAUTION!

Replacing fuel system components with non-ethanol
compatible components can damage your vehicle.

Maintenance

CAUTION!

Do not use ethanol mixture greater than 85% in your
vehicle. It will cause difficulty in cold starting and
may affect driveability.

309

ADDING FUEL

Fuel Filler Cap (Gas Cap)

The gas cap is located behind the fuel filler door. When
fueling, the cap may be placed on the inside of the filler
door.

If the gas cap is lost or damaged, be sure the replacement
cap is for use with this vehicle.

CAUTION!

• Damage to the fuel system or emissions control

system could result from using an improper fuel
tank filler tube cap (gas cap). A poorly fitting cap
could let impurities into the fuel system.

• To avoid fuel spillage and overfilling, do not “top

off” the fuel tank after filling.

WARNING!

• Never allow any lit smoking materials near the

vehicle while removing the cap or filling the tank.

STARTING AND OPERATING

WARNING! (Continued)

• Never add fuel to the vehicle when the engine is

running. This is in violation of most state and
federal regulations and may cause the “Malfunc-
tion Indicator Light (MIL)” to turn on.

• A fire may result if gasoline is pumped into a

portable container that is inside of a vehicle or on
a truck bed. You could be burned. Always place
gas containers on the ground while filling.

NOTE:

• If fuel is poured from a portable container, the con-

tainer should have a flexible nozzle long enough to
extend into the fuel filler tube.

• When the fuel nozzle “clicks” or shuts off, the fuel

tank is full.

• Tighten the gas cap until you hear a “clicking” sound.

This is an indication that the gas cap is properly
tightened. Make sure that the gas cap is tightened each
time the vehicle is refueled.

Loose Fuel Filler Cap Message
After fuel has been added, the vehicle diagnostic system
can determine if the fuel filler cap is possibly loose,
improperly installed, or damaged. If the system detects a
malfunction, the “gASCAP” message will display in the
odometer display. Tighten the gas cap until a

⬙clicking⬙

sound is heard. This is an indication that the gas cap is
properly tightened. Press the odometer reset button to
turn the message off. If the problem persists, the message
will appear the next time the vehicle is started. This
might indicate a damaged cap. If the problem is detected
twice in a row, the system will turn on the MIL. Resolving
the problem will turn the MIL off.

VEHICLE LOADING

Certification Label
As required by National Highway Traffic Safety Admin-
istration Regulations, your vehicle has a certification
label affixed to the driver’s side door.

This label contains the month and year of manufacture,
Gross Vehicle Weight Rating (GVWR), Gross Axle Weight
Rating (GAWR) front and rear, and Vehicle Identification
Number (VIN). A Month-Day-Hour (MDH) number is
included on this label and shows the month, day, and
hour of manufacture. The bar code that appears on the
bottom of the label is your Vehicle Identification Number
(VIN).

Gross Vehicle Weight Rating (GVWR)
The GVWR is the total permissible weight of your vehicle
including driver, passengers, vehicle, options, and cargo.
The label also specifies maximum capacities of front and
rear axle systems. Total load must be limited so that
GVWR is not exceeded.

Payload
The payload of a vehicle is defined as the allowable load
weight a vehicle can carry including the weight of the
driver, all passengers, options, and cargo.

Certification Label

312

STARTING AND OPERATING

Gross Axle Weight Rating (GAWR)
The GAWR is the maximum permissible load on the front
and rear axles. The load must be distributed in the cargo
area so that the GAWR of each axle is not exceeded.

Each axle GAWR is determined by the component in the
system with the lowest load carrying capacity (axle,
springs, tires, or wheels).

Heavier axles or suspension components sometimes
specified by purchasers for increased durability do not
necessarily increase the vehicle’s GVWR.

Tire Size
This is the minimum allowable tire size for your vehicle.
Replacement tires must be equal to the load capacity of
this tire size.

Rim Size
This is the rim size that is appropriate for the tire size
listed.

Inflation Pressure (Cold)
This is the cold tire inflation pressure for your vehicle for
all loading conditions up to full GAWR.

Curb Weight
The curb weight of a vehicle is defined as the total weight
of the vehicle with all fluids, including vehicle fuel, at full
capacity conditions, and with no occupants or cargo
loaded into the vehicle. The front and rear curb weight
values are determined by weighing your vehicle on a
commercial scale before any occupants or cargo are
added.

Loading
The actual total weight and the weight of the front and
rear of your vehicle at the ground can best be determined
by weighing it when it is loaded and ready for operation.

5

STARTING AND OPERATING

313

The entire vehicle should first be weighed on a commer-
cial scale to ensure that the GVWR has not been ex-
ceeded. The weight on the front and rear of the vehicle
should then be determined separately to be sure that the
load is properly distributed over front and rear axle.
Weighing the vehicle may show that the GAWR of either
the front or rear axles has been exceeded but the total
load is within the specified GVWR. If so, weight must be
shifted from front to rear or rear to front as appropriate
until the specified weight limitations are met.

Store heavier items down low and be sure that the weight
is distributed equally. Stow all loose items securely before
driving.

Improper weight distribution can have an adverse effect
on the way your vehicle steers and handles and the way
the brakes operate.

WARNING!

Do not load your vehicle any heavier than the GVWR
or the maximum front and rear GAWR. If you do,
parts on your vehicle can break, or it can change the
way your vehicle handles. This could cause you to
lose control and result in a collision. Also, overload-
ing can shorten the life of your vehicle.

TRAILER TOWING
In this section you will find safety tips and information
on limits to the type of towing you can reasonably do
with your vehicle. Before towing a trailer carefully re-
view this information to tow your load as efficiently and
safely as possible.

To maintain warranty coverage, follow the requirements
and recommendations in this instruction concerning ve-
hicles used for trailer towing.

314

STARTING AND OPERATING

Common Towing Definitions
The following trailer towing related definitions will assist
you in understanding the following information:

Gross Vehicle Weight Rating (GVWR)
The GVWR is the total allowable weight of your vehicle.
This includes driver, passengers, cargo and tongue
weight. The total load must be limited so that you do not
exceed the GVWR. Refer to “Vehicle Loading/Vehicle
Certification Label” in “Starting and Operating” for
further information.

Gross Trailer Weight (GTW)
The GTW is the weight of the trailer plus the weight of all
cargo, consumables and equipment (permanent or tem-
porary) loaded in or on the trailer in its

⬙loaded and

ready for operation

⬙ condition.

The recommended way to measure GTW is to put your
fully loaded trailer on a vehicle scale. The entire weight
of the trailer must be supported by the scale.

Gross Combination Weight Rating (GCWR)
The GCWR is the total permissible weight of your vehicle
and trailer when weighed in combination.

NOTE:

The GCWR rating includes a 150 lbs (68 kg)

allowance for the presence of a driver.

Gross Axle Weight Rating (GAWR)
The GAWR is the maximum capacity of the front and rear
axles. Distribute the load over the front and rear axles
evenly. Make sure that you do not exceed either front or rear
GAWR. Refer to “Vehicle Loading/Vehicle Certification
Label” in “Starting and Operating” for further information.

WARNING!

It is important that you do not exceed the maximum
front or rear GAWR. A dangerous driving condition
can result if either rating is exceeded. You could lose
control of the vehicle and have a collision.
