414 Vehicle Care
{Warning
Rust or dirt on a wheel, or on the
parts to which it is fastened, can
make wheel nuts become loose
after time. The wheel could come
off and cause an accident. When
changing a wheel, remove any
rust or dirt from places where the
wheel attaches to the vehicle. In
an emergency, a cloth or a paper
towel can be used; however, use
ascraperorwirebrushlaterto
remove all rust or dirt.
Lightly coat the inner diameter of
the wheel hub opening with
wheel bearing grease after a
wheel change or tire rotation to
prevent corrosion or rust
build-up. Do not get grease on
the flat wheel mounting surface
or on the wheel nuts or bolts.
Reset the Tire Pressure Monitor
System (TPMS), if the vehicle
has one. SeeTire Pressure
Monitor Operation0408.
Check that the spare tire, if the
vehicle has one, is stored
properly. Push, pull, and then try
to rotate or turn the tire. If it
moves, tighten the cable. See
“Storing a Flat or Spare Tire and
To o l s”underTire
Changing0422.
When It Is Time for New
Tires
Factors, such as maintenance,temperatures, driving speeds,vehicle loading, and road conditionsaffect the wear rate of the tires.
Treadwear indicators are one way totell when it is time for new tires.Treadwear indicators appear whenthe tires have only 1.6 mm (1/16 in)or less of tread remaining. Somecommercial truck tires may not havetreadwear indicators. SeeTireInspection0411andTire Rotation0412for additional information.
The rubber in tires ages over time.This also applies to the spare tire,if the vehicle has one, even if it isnever used. Multiple factorsincluding temperatures, loadingconditions, and inflation pressuremaintenance affect how fast agingtakes place. GM recommends thattires, including the spare ifequipped, be replaced after sixyears, regardless of tread wear. Thetire manufacture date is the last fourdigits of the DOT Tire IdentificationNumber (TIN) which is molded intoone side of the tire sidewall. Thefirst two digits represent the week(01-52) and the last two digits, theyear. For example, the third week ofthe year 2010 would have afour-digit DOT date of 0310.

Vehicle Data
Recording and
Privacy
The vehicle has a number ofcomputers that record informationabout the vehicle’sperformanceandhow it is driven. For example, thevehicle uses computer modules tomonitor and control engine andtransmission performance, tomonitor the conditions for airbagdeployment and deploy them in acrash, and, if equipped, to provideantilock braking to help the drivercontrol the vehicle. These modulesmay store data to help the dealertechnician service the vehicle.Some modules may also store dataabout how the vehicle is operated,such as rate of fuel consumption oraverage speed. These modules mayretain personal preferences, such asradio presets, seat positions, andtemperature settings.
Event Data Recorders
This vehicle is equipped with anevent data recorder (EDR). Themain purpose of an EDR is torecord, in certain crash or nearcrash-like situations, such as an airbag deployment or hitting a roadobstacle, data that will assist inunderstanding how a vehicle’ssystems performed. The EDR isdesigned to record data related tovehicle dynamics and safetysystems for a short period of time,typically 30 seconds or less. TheEDR in this vehicle is designed torecord such data as:
.How various systems in yourvehicle were operating;
.Whether or not the driver andpassenger safety belts werebuckled/fastened;
.How far (if at all) the driver wasdepressing the accelerator and/or brake pedal; and,
.How fast the vehicle wastraveling.
