selection of Tow/Haul when thevehicle is unloaded. Such aselection when unloaded may resultin unpleasant engine andtransmission driving characteristicsand reduced fuel economy. Tow/Haul is recommended only whenpulling a heavy trailer or a large orheavy load.
Integrated Trailer Brake
Control System
The vehicle may have an IntegratedTrailer Brake Control (ITBC) systemfor use with electric trailer brakes ormost electric over hydraulic trailerbrakes.
This symbol is on the Trailer BrakeControl Panel on vehicles with anITBC system. The power output tothe trailer brakes is based on theamount of brake pressure beingapplied by the vehicle’sbrake
system, and on the type of trailerbrakes detected. This availablepower output to the trailer brakescan be adjusted to a wide range oftrailering situations.
The ITBC system is integrated withthe vehicle’sbrake,antilockbrake,and StabiliTrak systems. In traileringconditions that cause the vehicle’santilock brake or StabiliTraksystems to activate, power sent tothe trailer's brakes will beautomatically adjusted to minimizetrailer wheel lock-up. This does notimply that the trailer has StabiliTrak.
If the vehicle’sbrake,antilockbrake,or StabiliTrak systems are notfunctioning properly, the ITBCsystem may not be fully functionalor may not function at all. Make sureall of these systems are fullyoperational to ensure fullfunctionality of the ITBC system.
The ITBC system is poweredthrough the vehicle's electricalsystem. Turning the ignition off willalso turn off the ITBC system. TheITBC system is fully functional onlywhen the ignition is in ON/RUN.
{Warning
Connecting a trailer that has an
air brake system may result in
reduced or complete loss of trailer
braking. There may be an
increase in stopping distance or
trailer instability which could
result in personal injury or
damage to the vehicle, trailer,
or other property. Use the ITBC
system only with electric or
electric over hydraulic trailer
brakes.

Engine Oil
For diesel engine vehicles, see“Engine Oil”in the Duramax dieselsupplement.
To e n s u r e p r o p e r e n g i n eperformance and long life, carefulattention must be paid to engine oil.Following these simple, butimportant steps will help protectyour investment:
.Use engine oil approved to theproper specification and of theproper viscosity grade. See“Selecting the Right Engine Oil”in this section.
.Check the engine oil levelregularly and maintain theproper oil level. See“CheckingEngine Oil”and“When to AddEngine Oil”in this section.
.Change the engine oil at theappropriate time. SeeEngine OilLife System0362.
.Always dispose of engine oilproperly. See“What to Do withUsed Oil”in this section.

When to Check and Change
Automatic Transmission Fluid
It is usually not necessary to checkthe transmission fluid level. The onlyreason for fluid loss is atransmission leak or overheatedtransmission. If a small leak issuspected, then use the followingchecking procedures to check thefluid level. However, if there is alarge leak, then it may be necessaryto have the vehicle towed to a
dealer service department and haveit repaired before driving the vehiclefurther.
Caution
Use of the incorrect automatic
transmission fluid may damage
the vehicle, and the damage may
not be covered by the vehicle
warranty. Always use the
automatic transmission fluid listed
inRecommended Fluids and
Lubricants0462.
Change the fluid and filter at thescheduled maintenance intervalslisted inMaintenance Schedule0452.Besuretousethetransmission fluid listed inRecommended Fluids andLubricants0462.

damage the transmission. Too
much can mean that some of the
fluid could come out and fall on
hot engine parts or exhaust
system parts, starting a fire. Too
little fluid could cause the
transmission to overheat. Be sure
to get an accurate reading if
checking the transmission fluid.
Before checking the fluid level,prepare the vehicle:
1. Start the engine and park thevehicle on a level surface.Keep the engine running.
2. Apply the parking brake andplace the shift lever in P (Park).
3. With your foot on the brakepedal, move the shift leverthrough each gear range,pausing for about

three seconds in each range.Then, move the shift lever backto P (Park).
4. Allow the engine to idle (500–800 rpm) for at leastone minute. Slowly release thebrake pedal.
5. Keep the engine running andcheck the transmission fluidtemperature on the DriverInformation Center (DIC). SeeDriver Information Center (DIC)(Base Level)0145orDriverInformation Center (DIC)(Uplevel)0147.
6. Using the transmission fluidtemperature reading, determineand perform the appropriatecheck procedure. If thetransmission fluid temperaturereading is not within therequired temperature ranges,allow the vehicle to cool,or operate the vehicle until theappropriate transmission fluidtemperature is reached.
Cold Check Procedure
Use this procedure only as areference to determine if thetransmission has enough fluid to beoperated safely until a hot checkprocedure can be made. The hotcheck procedure is the mostaccurate method to check the fluidlevel. Perform the hot checkprocedure at the first opportunity.Use this cold check procedure tocheck fluid level when thetransmission temperature isbetween 27 °C and 32 °C (80 °F and90 °F).
1. Locate the transmissiondipstick at the rear of theengine compartment, on thepassenger side of the vehicle.
SeeEngine CompartmentOverview0354.
2. Flip the handle up, then pull outthe dipstick and wipe it with aclean rag or paper towel.
3. Install the dipstick by pushing itback in all the way; waitthree seconds, and then pull itback out again.
4. Check both sides of thedipstick and read the lowerlevel. Repeat the checkprocedure to verify the reading.
5. If the fluid level is below theCOLD check band, add onlyenough fluid as necessary tobring the level into the COLDband. It does not take muchfluid, generally less than 0.5 L(1 pt). Do not overfill.

6. Perform a hot check at the firstopportunity after thetransmission reaches a normaloperating temperature between71 °C to 93 °C (160 °F to200 °F).
7. If the fluid level is in theacceptable range, push thedipstick back in all the way,then flip the handle down tolock the dipstick in place.
Hot Check Procedure
Use this procedure to check thetransmission fluid level when thetransmission fluid temperature isbetween 71 °C and 93 °C (160 °Fand 200 °F).
The hot check is the most accuratemethod to check the fluid level. Thehot check should be performed atthe first opportunity in order to verifythe cold check. The fluid level risesas fluid temperature increases, so itis important to ensure thetransmission temperature is withinrange.
1. Locate the transmissiondipstick at the rear of theengine compartment, on thepassenger side of the vehicle.
SeeEngine CompartmentOverview0354.
2. Flip the handle up, then pull outthe dipstick and wipe it with aclean rag or paper towel.
3. Install the dipstick by pushing itback in all the way; waitthree seconds, and then pull itback out again.
4. Check both sides of thedipstick and read the lowerlevel. Repeat the checkprocedure to verify the reading.
5. Safe operating level is withinthe HOT cross hatch band onthe dipstick. If the fluid level isnot within the HOT band, andthe transmission temperature isbetween 71 °C and 93 °C(160 °F and 200 °F), add ordrain fluid as necessary tobring the level into the HOTband. If the fluid level is low,add only enough fluid to bringthe level into the HOT band.It does not take much fluid,generally less than 0.5 L (1 pt).Do not overfill.
6. If the fluid level is in theacceptable range, push thedipstick back in all the way,then flip the handle down tolock the dipstick in place.
