system might indicate that an oilchange is not necessary for up to ayear. The engine oil and filter mustbe changed at least once a yearand, at this time, the system mustbe reset. Your dealer has trainedservice people who will perform thiswork and reset the system. It is alsoimportant to check the oil regularlyover the course of an oil draininterval and keep it at the properlevel.
If the system is ever resetaccidentally, the oil must bechanged at 5 000 km (3,000 mi)since the last oil change.Remember to reset the oil lifesystem whenever the oil is changed.
How to Reset the Engine Oil
Life System
Reset the system whenever theengine oil is changed so that thesystem can calculate the nextengine oil change. To reset thesystem:
1. Turn the ignition key to ON/RUN with the engine off.
2. Fully press and release theaccelerator pedal slowly threetimes within five seconds.
3. Turn the key to LOCK/OFF.
If the CHANGE ENGINE OIL SOONmessage comes back on when thevehicle is started, the engine oil lifesystem has not reset. Repeat theprocedure.
Automatic Transmission
Fluid
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, use the followingprocedures to check the fluid level.However, if there is a large leak, itmay be necessary to have thevehicle towed to a dealer and haveit repaired before driving the vehiclefurther.
Change the fluid and filter at theintervals listed inMaintenanceSchedule0297,andbesuretousethe transmission fluid listed inRecommended Fluids andLubricants0305.
How to Check Automatic
Transmission Fluid
Because this operation can bedifficult, it is recommended to havethis check done at your dealer,which can monitor the transmissiontemperature. The transmission fluidlevel increases with temperature. Toobtain a highly accurate fluid levelcheck, the transmission temperaturemust be measured.
If it is decided to check the fluidlevel, be sure to follow all theinstructions here, or a false readingon the dipstick may occur.

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.
Wait at least 30 minutes with theengine off, before checking thetransmission fluid level if the vehiclehas been driven:
.In hot weather, when outsidetemperatures are above 32 °C(90 °F).
.The vehicle is heavily loaded.
.At high speed for quite a while inhot weather.
.In heavy traffic and hot weather.
.While pulling a trailer.
After driving under these conditions,ahotcheckcanbeperformed.Thefluid should be hot, which is 71 °C to93 °C (160 °F to 200 °F).
Acoldfluidlevelcheckcanbeperformed after the vehicle hasbeen sitting for eight hours or morewith the engine off, but this is usedonly as a reference. Let the enginerun at idle for five minutes if theoutside temperature is between 15 °Cto32°C(60°Fto90°F).Shouldthe fluid level be low during this coldcheck, the fluid must be checkedwarm or hot before adding fluid.If the outside temperature is colderthan 15 °C (60 °F) or hotter than 32 °C(90°F),acoldcheckcannotbeperformed.
Awarmfluidlevelcheckcanbeperformed by driving the vehicleunder lightly loaded conditions andoutside temperatures between 10 °Cto 27 °C (50 °F to 80 °F). Thevehicle should be driven for at least24 km (15 mi) before performing awarm check. Checking the fluidwarm or hot will give a moreaccurate reading of the fluid levelthan a cold check.
Because the vehicle is equippedwith a high-efficiency air-to-oilcooler, the transmission fluidtemperature may not reach the
required hot fluid level checkingtemperature under normal lightlyloaded driving vehicle conditions.
Checking the Fluid Level
Prepare the vehicle:
1. Park the vehicle on a levelplace. Keep the enginerunning.
2. With the parking brake applied,place the shift lever in P (Park).
3. With a foot on the brake pedal,move the shift lever througheach gear range, pausing forabout three seconds in eachrange. When M is reached,move the selector from M1through M3. Then, position theshift lever in P (Park).
4. Let the engine run at idle fortwo minutes or more.
Then, without shutting off theengine, use the steps that follow.

or bodies of water. Have the coolantchanged by an authorized servicecenter, familiar with legalrequirements regarding usedcoolant disposal. This will helpprotect the environment and yourhealth.
Checking Coolant
The vehicle must be on a levelsurface when checking the coolantlevel.
Check to see if coolant is visible inthe coolant recovery tank. If thecoolant inside the coolant recoverytank is boiling, do not do anythingelse until it cools down. If coolant isvisible but the coolant level is not ator above the COLD FILL mark, adda50/50mixtureofclean,drinkablewater and DEX-COOL coolant at thecoolant recovery tank, but be surethe cooling system is cool beforethis is done.
The coolant recovery tank cap hasthis symbol on it.
When the engine is cold, the coolantlevel should be at or above theCOLD FILL mark. If it is not, therecould be a leak in the coolingsystem.
If the coolant is low, add the coolantor take the vehicle to a dealer forservice.

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.
Caution
This vehicle has a specific
coolant fill procedure. Failure to
follow this procedure could cause
the engine to overheat and be
severely damaged.
If coolant is needed, add the properDEX-COOL coolant mixture at thecoolant recovery tank.

Radiator
{Warning
Steam and scalding liquids from a
hot cooling system can blow out
and burn you badly. Never turn
the cap when the cooling system,
including the surge tank pressure
cap, is hot. Wait for the cooling
system and surge tank pressure
cap to cool.

.Trained dealer technicians haveaccess to tools and equipmentto inspect the brakes andrecommend quality partsengineered for the vehicle.
Fluids
Proper fluid levels and approvedfluids protect the vehicle’ssystemsand components. SeeRecommended Fluids andLubricants0305for GM approvedfluids.
.Engine oil and windshieldwasher fluid levels should bechecked at every fuel fill.
.Instrument cluster lights maycome on to indicate that fluidsmay be low and need to befilled.
Hoses
Hoses transport fluids and shouldbe regularly inspected to ensurethat there are no cracks or leaks.With a multi-point inspection, yourdealer can inspect the hoses andadvise if replacement is needed.
Lamps
Properly working headlamps,taillamps, and brake lamps areimportant to see and be seen onthe road.
.Signs that the headlamps needattention include dimming, failureto light, cracking, or damage.The brake lamps need to bechecked periodically to ensurethat they light when braking.
.With a multi-point inspection,your dealer can check the lampsand note any concerns.
Shocks and Struts
Shocks and struts help aid in controlfor a smoother ride.
.Signs of wear may includesteering wheel vibration, bounce/sway while braking, longerstopping distance, or uneventire wear.
.As part of the multi-pointinspection, trained dealertechnicians can visually inspectthe shocks and struts for signs
of leaking, blown seals,or damage, and can advisewhen service is needed.
Tires
Tires need to be properly inflated,rotated, and balanced. Maintainingthe tires can save money and fuel,and can reduce the risk of tirefailure.
.Signs that the tires need to bereplaced include three or morevisible treadwear indicators; cordor fabric showing through therubber; cracks or cuts in thetread or sidewall; or a bulge orsplit in the tire.
