Information

Transmission

Cold Operation

(Allison Transmission)

When temperatures are very cold,

the transmission will prevent certain

operations to protect against

damage. The chart below shows

shift range availability based on

transmission oil temperature:

.All shift ranges available at

−25 C (−13 F) or above.

.2 (Second) and 3 (Third) shift

ranges only at −35 C (−31 F) to

−25 C (−13 F).

.2 (Second) shift range only at

−35 C (−31 F) or lower.

Torque converter clutch operation

will also be prevented when air or

transmission oil temperatures are

below certain levels.

For areas where ambient

temperatures are below

−40 C (−40 F), use synthetic

transmission fluid approved to

Allison Transmission specification

TES‐295. See Recommended

Fluids and Lubricants on page 11‑8

and Automatic Transmission Fluid

on page 10‑11.

Adaptive Shift Controls

The shift quality of a new vehicle

may not be ideal because the

Adaptive Shift Control process may

not have determined the best

settings for a particular shift or

condition. Shift quality will improve

with continued driving.

Low Traction Mode

(Allison Transmission)

Low Traction Mode aids in vehicle

acceleration on slippery road

surfaces such as ice or snow.

By selecting 2 (Second) using

Range Selection Mode while at a

stop, the transmission will limit

torque to the drive wheels to

prevent slippage.

Black plate (2,1)

DURAMAX Diesel Engine (LML/LGH) - 2011

1-2 In Brief

Heater Performance Mode

(Allison Transmission)

When cold weather conditions are

detected, the transmission raises

part throttle upshift points after

the 1 (First) to 2 (Second) upshift

to increase engine speed.

This feature shortens engine and

cab warm up times.

When the transmission is in this

mode, upshifts may be delayed.

This is normal and does not

indicate an operational problem.

Four Wheel Drive

(Allison Transmission)

When operating in 4↓

(Four-Wheel-Drive Low), there

is a very deep gear reduction.

The resulting shifts will feel

exaggerated.

Performance and

Maintenance

Engine Oil Life System

The engine oil life system calculates

engine oil life based on vehicle use

and, on most vehicles, displays a

DIC message when it is necessary

to change the engine oil and filter.

The oil life system should be reset

only following an oil change.

Resetting the Oil Life System

To reset the Engine Oil Life System

on van models:

1. Display the OIL LIFE

REMAINING on the DIC.

2. Press and hold the SET/RESET

button on the DIC for more than

five seconds. The oil life will

change to 100%.

To reset the Engine Oil Life System

on most pickup models:

1. Display the OIL LIFE

REMAINING on the DIC. If the

vehicle does not have DIC

buttons, the vehicle must be in

P (Park) to access this display.

2. Press and hold the SET/RESET

button on the DIC, or the trip

odometer reset stem if the

vehicle does not have DIC

buttons, for more than

five seconds. The oil life will

change to 100%.

DURAMAX Diesel Engine (LML/LGH) - 2011

In Brief 1-3

On all models, the Engine Oil Life

System can be reset as follows:

1. Turn the ignition to ON/RUN with

the engine off

2. Fully press the accelerator pedal

slowly three times within

five seconds.

3. Display the OIL LIFE

REMAINING on the DIC. If the

display shows 100%, the system

is reset.

4. Turn the key to LOCK/OFF.

See Engine Oil Life System on

page 10‑10.

Diesel Particulate Filter

(Exhaust Filter)

The Duramax engine is equipped

with a Diesel Particulate Filter (DPF)

that, by design, will filter or trap

particulates. The DPF is located

under the vehicle in the exhaust

system and looks like a catalyst.

Depending on a number of factors

monitored by the engine computer,

the DPF will need to be cleaned of

accumulated solids. When a

cleaning is needed, the engine

computer will initiate a cleaning

action by warming the exhaust gas

temperature. This feature has been

designed to operate automatically,

with limited operator involvement or

awareness.

Cleaning the DPF

(Exhaust Filter)

While the DPF cleaning is

automatically controlled by the

engine computer, the vehicle will

need to operate continuously for

approximately 30 minutes and at

speeds greater than 48 km/h

(30 mph) to clean the DPF

effectively. If the vehicle is returned

to idle during the cleaning process,

the driver may notice a slightly

different sound or a slightly elevated

engine idle speed. This is normal.

No action is required on the part of

the driver during a regular DPF

cleaning. See Diesel Particulate

Filter (Exhaust Filter) on page 9‑10.

Black plate (4,1)

DURAMAX Diesel Engine (LML/LGH) - 2011

1-4 In Brief

Special DPF Driver Messages

If the vehicle is used for numerous

short trips or extended slow-speed

operation, the engine computer may

not be able to adequately heat up

the exhaust system to clean the

DPF effectively. The engine

computer has been designed to

continuously monitor the condition

of the DPF. When the engine

computer detects that the DPF is

nearly full of particulates and that

the vehicle is not being operated in

a manner that would allow effective

automatic DPF cleaning, the Driver

Information Center will display the

message CLEANING EXHAUST

FILTER KEEP DRIVING UNTIL

MESSAGE IS CLEARED.

If the vehicle continues to be

driven in a manner that prevents

effective DPF cleaning, the DPF will

become plugged with particulates.

If this occurs, the engine computer

will turn on the Service Engine Soon

Light in the instrument cluster and

the DIC will display the message

REDUCED ENGINE POWER.

See Diesel Particulate Filter

(Exhaust Filter) on page 9‑10

and Engine Power Messages on

page 5‑11.

Fuel

Use Ultra-Low Sulfur Diesel

Fuel (ULSD)

Use Ultra-Low Sulfur Diesel Fuel

(ULSD) only. The emission control

hardware used on the vehicle may

be damaged by using fuel with high

sulfur levels. Use only fuel that is

dispensed from pumps bearing the

ULSD label.

Do Not Use Low Sulfur Diesel

Fuel (LSD)

Do not use fuel that is dispensed

from pumps bearing the LSD label.

Do Not Use Non-Highway Fuel

Fuel labeled as off road or

non-highway is typically very

high in sulfur content and will

damage the emission control

system. Non-Highway fuel is not

intended for use in on-highway

vehicles and does not have the

fuel properties needed by the

DPF-equipped Duramax Diesel.

In addition:

.Use the correct engine oil.

.Do not add gasoline to

diesel fuel.

.Do not modify the induction or

exhaust systems.

See Fuel for Diesel Engines on

page 9‑17 and Engine Oil on

page 10‑7.

Diesel Exhaust Fluid

Diesel Exhaust Fluid (DEF) is used

with diesel engines to reduce the

amount of regulated emissions

produced. The DEF system must be

maintained for the vehicle to run

properly.

Locating Diesel Exhaust Fluid

DEF can be purchased at a

Chevrolet or GMC dealer. It can

also be purchased at authorized

vehicle and truck dealerships.

Additionally, some diesel truck

fuelling stations or retailers may

also have DEF for purchase. For

vehicles with an active OnStar

subscription, OnStar can help to

locate a DEF retailer. For more

information on locating DEF see

www.afdc.energy.gov/afdc/vehicles/

diesels_fluid.html. See “Customer

Assistance Offices”in the owner

manual for phone numbers to assist

you in contacting a GM dealer.

See Recommended Fluids and

Lubricants on page 11‑8.

As the DEF tank becomes low

on fluid, warnings begin with

approximately 1600 km (1000 miles)

of remaining range. These warnings

will increase in intensity as the tank

becomes empty. Once the tank is

empty, the vehicle will be speed

limited to 89 km/h (55 mph) and

eventually to 7km/h (4 mph).

The tank should be refilled to

avoid vehicle speed limitation.

If there is an issue with the quality

of the fluid or the exhaust fluid

system, warnings will be displayed

in the Driver Information Center

(DIC). The vehicle will have 322 km

(200 miles) before being speed

limited to 89 km/h (55 mph). If the

vehicle continues to be driven in this

condition, it will become speed

limited to 7km/h (4 mph). See Diesel

Exhaust Fluid on page 9‑12.
