4. Check both sides of the dipstick and read the lower level. Repeat the check procedure to verify the reading.


5.


If the fluid level is below the COLD check band, add only enough fluid as necessary to bring the level into the COLD band. It does not take much fluid, generally less than 0.5 Liter (1 Pint). Do not overfill.


6. Perform a hot check at the


first opportunity after the transmission reaches a normal operating temperature between 60°C and 75°C (140°F and 167°F). If the fluid level is in the acceptable range, push the dipstick back in all the way.


7.


Hot Check Procedure Use this procedure to check the transmission fluid level when the transmission fluid temperature is between 60°C and 75°C (140°F and 167°F). The hot check is the most accurate method to check the fluid level. The hot check should be performed at the first opportunity in order to verify the cold check. The fluid level rises as fluid temperature increases, so it is important to ensure the transmission temperature is within range.

5. Safe operating level is within the


HOT cross hatch band on the dipstick. If the fluid level is not within the HOT band, and the transmission temperature is between 60°C and 75°C (140°F and 167°F), add or drain fluid as necessary to bring the level into the HOT band. If the fluid level is low, add only enough fluid to bring the level into the HOT band. It does not take much fluid, generally less than 0.5 Liter (1 Pint). Do not overfill. If the fluid level is in the acceptable range, push the dipstick back in all the way.


6.


Consistency of Readings Always check the fluid level at least twice using the procedure described previously. Consistency (repeatable readings) is important to maintaining proper fluid level. If readings are still inconsistent, contact your dealer.


Drive Motor/Generator Control Module (DMCM) Coolant Surge Tank Pressure Cap


See Engine Compartment Overview on page 10‑4 for more information on location. The Drive Motor/Generator Control Module (DMCM) coolant surge tank pressure cap must be fully installed on the hybrid coolant surge tank.


Notice: If the pressure cap is not tightly installed, coolant loss and possible damage to the Drive Motor/Generator Control Module (DMCM) may occur. Be sure the cap is properly and tightly secured.


Drive Motor/Generator Control Module (DMCM) Cooling System In addition to the regular cooling system, the vehicle also has a cooling system for the DMCM system. This system is serviced differently than the vehicle's main cooling system. The DMCM cooling system includes the DMCM coolant surge tank, DMCM surge tank pressure cap, DMCM cooling pumps, hybrid cooling radiator and the Drive Motor/Generator Control Module (DMCM).

How to Add Coolant to the DMCM Coolant Surge Tank


{ WARNING


{ WARNING


You can be burned if you spill coolant on hot engine parts. Coolant contains ethylene glycol and it will burn if the engine parts are hot enough. Do not spill coolant on a hot engine.


If the DMCM coolant is empty , the vehicle must be serviced by your dealer and a special fill procedure must be followed. Notice: Attempting to fill the DMCM cooling surge tank yourself when the fluid level is empty can damage your vehicle. Your vehicle must be serviced.


Steam and scalding liquids from a hot cooling system can blow out and burn you badly. They are under pressure, and if you turn the coolant surge tank pressure cap — even a little — they can come out at high speed. Never turn the cap when the cooling system, including the coolant surge tank pressure cap, is hot. Wait for the cooling system and coolant surge tank pressure cap to cool if you ever have to turn the pressure cap.


Notice: Using coolant other than a pre‐mixed DEX-COOL, available at your dealer, may damage your vehicle. Any repairs would not be covered by your warranty. Always use a pre‐mixed DEX-COOL (silicate-free) coolant in your vehicle.


If no problem has been found yet, check to see if coolant is visible in the DMCM coolant surge tank. If coolant is visible, add pre‐mixed DEX-COOL coolant, available at your dealer, at the DMCM coolant surge tank, but be sure the DMCM cooling system, including the DMCM coolant surge tank pressure cap, is cool before you do it. Use the procedure following.

4. Turn the ignition to ON/RUN


without starting the engine. The hybrid cooling pumps will run and any trapped air will purge to the surge tank.


5. Add the pre‐mixed DEX‐COOL, available at your dealer, until the coolant level is maintained at the FULL COLD mark. This should take no longer than two minutes of hybrid cooling pump operation. If the level cannot be kept at the FULL COLD level, the vehicle may need service. See your dealer.


1. Park the vehicle on a level


surface and turn the vehicle off. Remove the DMCM coolant surge tank pressure cap when the DMCM cooling system, including the DMCM coolant surge tank pressure cap and DMCM cooling hoses, are no longer hot. Turn the DMCM coolant surge tank pressure cap slowly counterclockwise (left) about one full turn. Wait 30 seconds.


2. Then keep turning the DMCM


coolant surge tank pressure cap slowly, and remove it.


3. Add the pre‐mixed DEX‐COOL, available at your dealer, to the DMCM coolant surge tank until the level reaches the FULL COLD mark.

6. Then replace the DMCM coolant


surge tank pressure cap. Be sure the pressure cap is hand-tight and fully seated.


Notice: Using tap water, cooling system sealers or conditioners in an attempt to stop coolant leaks can damage the DMCM and engine cooling systems. Never use tap water, cooling system sealers or conditioners in your cooling system.


Power Steering Fluid The vehicle has electric power steering and does not use power steering fluid.


Battery This vehicle has a standard 12‐volt battery and a high voltage hybrid battery. Refer to the replacement number on the original battery label when a new standard 12‐volt battery is needed. Only a trained service technician with the proper knowledge and tools should inspect, test, or replace the hybrid battery. See your dealer if the hybrid battery needs service.

Vehicle Care


If the vehicle's 12‐volt battery has run down, you may want to use another vehicle and some jumper cables to start your vehicle. Use the following steps to do it safely.


{ WARNING


Batteries can hurt you. They can be dangerous because:


. They contain acid that can


burn you.


. They contain gas that can


explode or ignite.


. They contain enough electricity to burn you.


If you do not follow these steps exactly, some or all of these things can hurt you.


Notice: Ignoring these steps could result in costly damage to the vehicle that would not be covered by the warranty.


Trying to start the vehicle by pushing or pulling it will not work, and it could damage the vehicle. 1. Check the other vehicle. It must


have a 12‐volt battery with a negative ground system.


Notice: Only use vehicles with 12-volt systems with negative grounds to jump start your vehicle. If the other vehicle's system is not a 12-volt system with a negative ground, both vehicles can be damaged. 2. Get the vehicles close enough


so the jumper cables can reach, but be sure the vehicles are not touching each other. It could cause a ground connection you do not want. You would not be able to start your vehicle, and the bad grounding could damage the electrical systems.


To avoid the possibility of the vehicles rolling, set the parking brake firmly on both vehicles involved in the jump start procedure. Put the automatic transmission in P (Park) or a manual transmission in N (Neutral) before setting the parking brake. If you have a four-wheel-drive vehicle, be sure the transfer case is in a drive gear, not in N (Neutral).


Notice: If you leave the radio or other accessories on during the jump starting procedure, they could be damaged. The repairs would not be covered by the warranty. Always turn off the radio and other accessories when jump starting the vehicle. 3. Turn off the ignition on both


vehicles. Unplug unnecessary accessories plugged into the cigarette lighter or the accessory power outlets. Turn off the radio and all the lamps that are not needed.


Silverado/Sierra Hybrid - 2011


Black plate (17,1)


This avoids sparks and helps save both batteries. It could save the radio!


4. Open the hood on the other


vehicle and locate the positive (+) and negative (−) terminal locations on that vehicle.


The positive (+) connection is located under a red plastic cover at the positive battery post. To uncover the remote positive (+) terminal, open the red plastic cover.


5. The remote negative (−) is a


solid engine ground.


{ WARNING


An electric fan can start up even when the engine is not running and can injure you. Keep hands, clothing and tools away from any underhood electric fan.


{ WARNING


Using an open flame near a battery can cause battery gas to explode. People have been hurt doing this, and some have been blinded. Use a flashlight if you need more light. Be sure the battery has enough water. You do not need to add water to the battery installed in your new vehicle. But if a battery has filler caps, be sure the right

amount of fluid is there. If it is low, add water to take care of that first. If you do not, explosive gas could be present. Battery fluid contains acid that can burn you. Do not get it on you. If you accidentally get it in your eyes or on your skin, flush the place with water and get medical help immediately.


{ WARNING


Fans or other moving engine parts can injure you badly. Keep your hands away from moving parts once the engine is running.


6. Check that the jumper cables do not have loose or missing insulation. If they do, you could get a shock. The vehicles could be damaged too.


Silverado/Sierra Hybrid - 2011


Black plate (18,1)


10-18


Vehicle Care


Before you connect the cables, here are some basic things you should know. Positive (+) goes to positive (+) or to a remote positive (+) terminal if the vehicle has one. Negative (−) will go to a heavy, unpainted metal engine part or a solid engine ground. Do not connect positive (+) to negative (−) or you will get a short that would damage the battery and maybe other parts too. Do not connect the negative (−) cable to the negative (−) terminal on the dead battery because this can cause sparks.


7. Connect the red positive (+)


cable to the positive (+) terminal of the vehicle with the dead battery. Use a remote positive (+) if the vehicle has one.


8. Do not let the other end touch


metal. Connect it to the positive (+) terminal of the good battery. Use a remote positive (+) if the vehicle has one.


9. Now connect the black


negative (−) cable to the negative (−) terminal of the good battery. Use a remote negative (−) if the vehicle has one. Do not let the other end touch anything until the next step. The other end of the negative (−) cable does not go to the dead battery. It goes to a heavy, unpainted metal engine part or to the remote negative (−) terminal on the vehicle with the dead battery.


10. Connect the other end of the


negative (−) cable to the remote negative (−) terminal, on the vehicle with the dead battery.


11. Now start the vehicle with the


good battery and run the engine for a while.


12. Try to start the vehicle that had


the dead battery. If it will not start after a few tries, it probably needs service.


Notice: If the jumper cables are connected or removed in the wrong order, electrical shorting may occur and damage the vehicle. The repairs would not be covered by the vehicle warranty. Always connect and remove the jumper cables in the correct order, making sure that the cables do not touch each other or other metal.


Silverado/Sierra Hybrid - 2011


Black plate (19,1)


To disconnect the jumper cables from both vehicles: 1. Disconnect the black


negative (−) cable from the vehicle that had the bad battery.


2. Disconnect the black


negative (−) cable from the vehicle with the good battery.


3. Disconnect the red positive (+) cable from the vehicle with the good battery.


4. Disconnect the red positive (+)


cable from the other vehicle.


5. Return the remote positive (+)


terminal cover to its original position.
