{Warning
For up to 10 seconds after the
vehicle is turned off and the
battery is disconnected, an airbag
can still inflate during improper
service. You can be injured if you
are close to an airbag when it
inflates. Avoid yellow connectors.
They are probably part of the
airbag system. Be sure to follow
proper service procedures, and
make sure the person performing
work for you is qualified to do so.
Adding Equipment to the
Airbag-Equipped Vehicle
Adding accessories that change thevehicle's frame, bumper system,height, front end, or side sheetmetal, may keep the airbag systemfrom working properly. Theoperation of the airbag system canalso be affected by changing anyparts of the front seats, safety belts,the airbag sensing and diagnosticmodule, steering wheel, instrumentpanel, any of the airbag modules,
ceiling headliner or pillar garnishtrim, overhead console, frontsensors, side impact sensors,or airbag wiring.
Yo u r d e a l e r a n d t h e s e r v i c e m a n u a lhave information about the locationof the airbag sensors, sensing anddiagnostic module, and airbagwiring.
In addition, the vehicle may have apassenger sensing system for thefront outboard passenger position,which includes sensors that are partof the passenger seat. Thepassenger sensing system may notoperate properly if the original seattrim is replaced with non-GMcovers, upholstery, or trim; or withGM covers, upholstery, or trimdesigned for a different vehicle. Anyobject, such as an aftermarket seatheater or a comfort-enhancing pador device, installed under or on topof the seat fabric, could alsointerfere with the operation of thepassenger sensing system. Thiscould either prevent properdeployment of the passengerairbag(s) or prevent the passengersensing system from properly
turning off the passenger airbag(s).SeePassenger SensingSystem082.
If the vehicle has rollover roof-railairbags, seeDifferent Size Tiresand Wheels0416for additionalimportant information.
If a snow plow is added to thevehicle, the airbags should still workproperly. The airbag systems weredesigned to work properly under awide range of conditions, includingsnow plowing with vehicles thathave the optional snow plow preppackage (RPO VYU). Do notchange or defeat the snow plow's“tripping mechanism.”If you do, itcan damage the snow plow and thevehicle, and may cause an airbagdeployment.
If you have to modify your vehiclebecause you have a disability andyou have questions about whetherthe modifications will affect thevehicle's airbag system, or if youhave questions about whether theairbag system will be affected if thevehicle is modified for any other

If you keep driving when the
engine is overheated, the liquids
in it can catch fire. You or others
could be badly burned. Stop the
engine if it overheats, and get out
of the vehicle until the engine
is cool.
If No Steam is Coming from
the Engine Compartment
The ENGINE OVERHEATED STOPENGINE or the ENGINEOVERHEATED IDLE ENGINEmessage, along with a low coolantcondition, can indicate a seriousproblem.
If there is an engine overheatwarning, but no steam is seen orheard, the problem may not be tooserious. Sometimes the engine canget a little too hot when the vehicle:
.Climbs a long hill on a hot day.
.Stops after high-speed driving.
.Idles for long periods in traffic.

If the ENGINE OVERHEATEDSTOP ENGINE or the ENGINEOVERHEATED IDLE ENGINEmessage appears with no sign ofsteam, try this for a minute or so:
1. Turn the air conditioning off.
2. Turn the heater on to thehighest temperature and to thehighest fan speed. Open thewindows as necessary.
3. When it is safe to do so, pull offthe road, shift to P (Park) orN(Neutral)andlettheengine idle.
If the temperature overheat gauge isno longer in the overheat zone or anoverheat warning no longer
displays, the vehicle can be driven.Continue to drive the vehicle slowlyfor about 10 minutes. Keep a safevehicle distance from the vehicle infront. If the warning does not comeback on, continue to drive normallyand have the cooling systemchecked for proper fill and function.
If the warning continues, pull over,stop, and park the vehicleright away.
If there is still no sign of steam andthe vehicle is equipped with anengine driven cooling fan, pushdown the accelerator until theengine speed is about twice as fastas normal idle speed for at leastfive minutes while the vehicle isparked. If the warning is still there,turn off the engine and get everyoneout of the vehicle until it cools down.
