FUEL QUALITY
Choosing the Right Fuel
Your vehicle is designed to operate on
regular unleaded gasoline with a minimum
pump (R+M)/2 octane rating of 87.
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 256).
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.
• Fuel containing more than 15% ethanol
or E85 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.
FUEL FILLER FUNNEL LOCATION

•
An open or pinched sensor hose.
• Incorrect engine oil level.
• Incorrect fuel for climatic conditions.
• Incorrect engine oil viscosity for climactic
conditions.
Note: Some vehicles have a lifetime fuel filter
that is integrated with the fuel tank. Regular
maintenance or replacement is not needed.
Note: If these checks do not help you correct
the concern, have your vehicle checked as
soon as possible.
Noise Emissions Warranty, Prohibited
Tampering Acts and Maintenance
On January 1, 1978, Federal regulation
became effective governing the noise
emission on trucks over 10,000 lb (4,536 kg)
Gross Vehicle Weight Rating (GVWR). The
preceding statements concerning prohibited
tampering acts and maintenance, and the
noise warranty found in the Warranty Guide,
are applicable to complete chassis cabs over
10,000 lb (4,536 kg)
GVWR. CATALYTIC CONVERTER WARNING:
Do not park, idle or drive
your vehicle on dry grass or other dry
ground cover. The emission system heats
up the engine compartment and exhaust
system, creating the risk of fire. WARNING:
The normal operating
temperature of the exhaust system is very
high. Never work around or attempt to
repair any part of the exhaust system until
it has cooled. Use special care when
working around the catalytic converter.
The catalytic converter heats up to a very
high temperature after only a short period
of engine operation and stays hot after the
engine is switched off. WARNING: Exhaust leaks may result
in entry of harmful and potentially lethal
fumes into the passenger compartment. If
you smell exhaust fumes inside your
vehicle, have your vehicle inspected
immediately. Do not drive if you smell
exhaust fumes. Your vehicle has various emission control
components and a catalytic converter that
enables it to comply with applicable exhaust
emission standards.
To make sure that the catalytic converter and
other emission control components continue
to work properly:
•
Do not crank the engine for more than
10 seconds at a time.
• Do not run the engine with a spark plug
lead disconnected.
• Do not push-start or tow-start your
vehicle. Use booster cables.
See Jump
Starting the Vehicle (page 267).
• Use only the specified fuel listed.
• Do not switch the ignition off when your
vehicle is moving.
• Avoid running out of fuel.
• Have the items listed in scheduled
maintenance information performed
according to the specified schedule.
Note: Resulting component damage may
not be covered by the vehicle Warranty.

GENERAL INFORMATION
Note:
Occasional brake noise is normal. If
a metal-to-metal, continuous grinding or
continuous squeal sound is present, the
brake linings may be worn-out. Have the
system checked by an authorized dealer. If
your vehicle has continuous vibration or
shudder in the steering wheel while braking,
have it checked by an authorized dealer.
Note: Brake dust may accumulate on the
wheels, even under normal driving
conditions. Some dust is inevitable as the
brakes wear and does not contribute to
brake noise. See Cleaning the Wheels
(page 331). See
Warning Lamps and
Indicators (page 104).
Wet brakes result in reduced braking
efficiency. Gently press the brake pedal a
few times when driving from a car wash or
standing water to dry the brakes. Brake Over Accelerator
In the event the accelerator pedal becomes
stuck or entrapped, apply steady and firm
pressure to the brake pedal to slow the
vehicle and reduce engine power. If you
experience this condition, apply the brakes
and bring your vehicle to a safe stop. Move
the transmission to park (P), switch the
engine off and apply the parking brake.
Inspect the accelerator pedal for any
interference. If none are found and the
condition persists, have your vehicle towed
to the nearest authorized dealer.
Brake Assist
Brake assist detects when you brake rapidly
by measuring the rate at which you press the
brake pedal. It provides maximum braking
efficiency as long as you press the pedal,
and can reduce stopping distances in critical
situations.
Anti-lock Brake System
This system helps you maintain steering
control during emergency stops by keeping
the brakes from locking. This lamp momentarily illuminates
when you switch the ignition on.
If the light does not illuminate
during start up, remains on or flashes, the
system may be disabled. Have the system
checked by an authorized dealer. If the
anti-lock brake system is disabled, normal
braking is still effective. If the brake warning lamp
illuminates when you release the
parking brake, have the system
checked by an authorized dealer. It also
illuminates momentarily when you switch the
ignition on to confirm the lamp is functional.
If it does not illuminate when you switch the
ignition on or begins to flash at any time,
have the system checked by an authorized
dealer.

AUTO HOLD
WARNING: The system does not
replace the parking brake. When you leave
your vehicle, always apply the parking
brake. WARNING: You must remain in your
vehicle when the system turns on. At all
times, you are responsible for controlling
your vehicle, supervising the system and
intervening, if required. Failure to take care
may result in the loss of control of your
vehicle, serious personal injury or death. WARNING:
The system will turn off
if a malfunction is apparent. Failure to take
care may result in the loss of control of
your vehicle, serious personal injury or
death. Auto Hold uses your vehicle's brakes to hold
your vehicle at a stop once your vehicle has
reached a standstill condition. For example,
Auto Hold can assist you while stopping at
traffic lights or while in traffic jams by holding
the brake pressure for you once you bring
your vehicle to a stop.
Switch Auto Hold off during vehicle or trailer
towing.
Note:
In case of a malfunction in the system
while Auto Hold actively holds the vehicle
(for example, low power supply), a message
appears in the information display asking
you to press the brake pedal. If you see this
message, press the brake pedal
immediately.
Note: Auto Hold only activates if the system
recognizes it is applying enough brake
pressure. On a steep hill or incline, you may
need to make sure the brake pedal is
pressed sufficiently to activate the Auto Hold
system. Note:
In some cases, Auto Hold might hand
over to the parking brake. When the parking
brake applies, the red brake lamp appears.
This is normal. When you press the
accelerator pedal, the drive away release
feature releases the parking brake.
Note: Auto Hold works on all road grades.
