or Off. The first button press showsthe current setting on the DIC.Additional button presses willchange this setting. The chosensetting will remain until it is changedand will affect the timing of both theCollision Alert and the TailgatingAlert features. The timing of bothalerts will vary based on vehiclespeed. The faster the vehicle speed,the farther away the alert will occur.Consider traffic and weatherconditions when selecting the alerttiming. The range of selectable alerttiming may not be appropriate for alldrivers and driving conditions.
Unnecessary Alerts
FCA may provide unnecessaryalerts for turning vehicles, vehiclesin other lanes, objects that are notvehicles, or shadows. These alertsare normal operation and thevehicle does not need service.
Cleaning the System
If the FCA system does not seem tooperate properly, cleaning theoutside of the windshield in front ofthe rearview mirror, and cleaning the
front of the vehicle where radarsensors are located, may correctthe issue.
Forward Automatic
Braking (FAB)
If the vehicle has Forward CollisionAlert (FCA), it also has FAB, whichincludes Intelligent BrakeAssist (IBA). When the systemdetects a vehicle ahead in your paththat is traveling in the samedirection that you may be about tocrash into, it can provide a boost tobraking or automatically brake thevehicle. This can help avoid orlessen the severity of crashes whendriving in a forward gear. Dependingon the situation, the vehicle mayautomatically brake moderately orhard. This forward automaticbraking can only occur if a vehicle isdetected. This is shown by the FCAvehicle ahead indicator being lit.SeeForward Collision Alert (FCA)System0304.
The system works when driving in aforward gear between 8 km/h(5 mph) and 80 km/h (37 mph).It can detect vehicles up toapproximately 60 m (197 ft).
{Warning

preparation feature and is not
designed to avoid crashes. Do
not rely on FAB to brake the
vehicle. FAB will not brake
outside of its operating speed
range and only responds to
detected vehicles.
FA B m a y n o t :
.Detect a vehicle ahead onwinding or hilly roads.
.Detect all vehicles,especially vehicles with atrailer, tractors, muddyvehicles, etc.
.Detect a vehicle whenweather limits visibility, suchas in fog, rain, or snow.

marking without using a turn signalin that direction. LDW uses acamera sensor to detect the lanemarkings at speeds of 56 km/h(35 mph) or greater.
{Warning
The LDW system does not steer
the vehicle. The LDW system
may not:
.Provide enough time toavoid a crash.
.Detect lane markings underpoor weather or visibilityconditions. This can occur ifthe windshield orheadlamps are blocked bydirt, snow, or ice; if they arenot in proper condition; or ifthe sun shines directly intothe camera.
.Detect road edges.
.Detect lanes on winding orhilly roads.
(Continued)
Warning (Continued)
If LDW only detects lane
markings on one side of the road,
it will only warn you when
departing the lane on the side
where it has detected a lane
marking. Always keep your
attention on the road and
maintain proper vehicle position
within the lane, or vehicle
damage, injury, or death could
occur. Always keep the
windshield, headlamps, and
camera sensors clean and in
good repair. Do not use LDW in
bad weather conditions.
How the System Works

When the System Does Not
Seem to Work Properly
The system may not detect lanes aswell when there are:
.Close vehicles ahead.
.Sudden lighting changes, suchas when driving through tunnels.
.Banked roads.

If the LDW system is not functioningproperly when lane markings areclearly visible, cleaning thewindshield may help.
LDW alerts may occur due to tarmarks, shadows, cracks in the road,temporary or construction lanemarkings, or other roadimperfections. This is normal systemoperation; the vehicle does not needservice. Turn LDW off if theseconditions continue.
Lane Keep Assist (LKA)
(1500 Series)
If equipped, LKA may help avoidcrashes due to unintentional lanedepartures. It may assist by gentlyturning the steering wheel if thevehicle approaches a detected lanemarking without using a turn signalin that direction. It may also provideaLaneDepartureWarning(LDW)system alert as the lane marking iscrossed. The LKA system will notassist or provide an LDW alert if itdetects that you are activelysteering. Override LKA by turningthe steering wheel. LKA uses a
camera to detect lane markingsbetween 60 km/h (37 mph) and180 km/h (112 mph).
{Warning
The LKA system does not
continuously steer the vehicle.
It may not keep the vehicle in the
lane or give a Lane Departure
Warning (LDW) alert, even if a
lane marking is detected.
The LKA and LDW systems
may not:
.Provide an alert or enoughsteering assist to avoid alane departure or crash.
.Detect lane markings underpoor weather or visibilityconditions. This can occur ifthe windshield orheadlamps are blocked bydirt, snow, or ice, if they arenot in proper condition, or ifthe sun shines directly intothe camera.
.Detect road edges.
(Continued)
Warning (Continued)
.Detect lanes on winding orhilly roads.
If LKA only detects lane markings
on one side of the road, it will
only assist or provide an LDW
alert when approaching the lane
on the side where it has detected
alanemarking.EvenwithLKA
and LDW, you must steer the
vehicle. Always keep your
attention on the road and
maintain proper vehicle position
within the lane, or vehicle
damage, injury, or death could
occur. Always keep the
windshield, headlamps, and
camera sensors clean and in
good repair. Do not use LKA in
bad weather conditions.

inflation pressure is high, press
on the metal stem in the center
of the tire valve to release air.
Re-check the tire pressure with
the tire gauge.
Put the valve caps back on the
valve stems to keep out dirt and
moisture and prevent leaks. Use
only valve caps designed for the
vehicle by GM. TPMS sensors
could be damaged and would
not be covered by the vehicle
warranty.
Tire Pressure for
High-Speed Operation
{Warning
Driving at high speeds, 160 km/h
(100 mph) or higher, puts
additional strain on tires.
Sustained high-speed driving
causes excessive heat buildup
and can cause sudden tire failure.
This could cause a crash, and
(Continued)
Warning (Continued)
you or others could be killed.
Some high-speed rated tires
require inflation pressure
adjustment for high-speed
operation. When speed limits and
road conditions allow the vehicle
to be driven at high speeds, make
sure the tires are rated for
high-speed operation, are in
excellent condition, and are set to
the correct cold tire inflation
pressure for the vehicle load.
Vehicles with P275/55R20 orP285/50R20 size tires requireinflation pressure adjustment whendriving the vehicle at speeds of160 km/h (100 mph) or higher. Setthe cold tire inflation pressure to20 kPa (3 psi) above therecommended cold tire pressureshown on the Tire and LoadingInformation label.
Return the tires to therecommended cold tire inflationpressure when high-speed drivinghas ended. SeeVehicle Load Limits0259andTire Pressure0405.
Tire Pressure Monitor
System
The Tire Pressure Monitor System(TPMS) uses radio and sensortechnology to check tire pressurelevels. The TPMS sensors monitorthe air pressure in your tires andtransmit tire pressure readings to areceiver located in the vehicle.
Each tire, including the spare (ifprovided), should be checkedmonthly when cold and inflated tothe inflation pressure recommendedby the vehicle manufacturer on thevehicle placard or tire inflationpressure label. (If your vehicle hastires of a different size than the sizeindicated on the vehicle placard ortire inflation pressure label, youshould determine the proper tireinflation pressure for those tires.)

408 Vehicle Care
As an added safety feature, yourvehicle has been equipped with atire pressure monitoring system(TPMS) that illuminates a low tirepressure telltale when one or moreof your tires is significantlyunder-inflated.
Accordingly, when the low tirepressure telltale illuminates, youshould stop and check your tires assoon as possible, and inflate themto the proper pressure. Driving on asignificantly under-inflated tirecauses the tire to overheat and canlead to tire failure. Under-inflationalso reduces fuel efficiency and tiretread life, and may affect thevehicle's handling and stoppingability.
Please note that the TPMS is not asubstitute for proper tiremaintenance, and it is the driver'sresponsibility to maintain correct tirepressure, even if under-inflation hasnot reached the level to triggerillumination of the TPMS low tirepressure telltale.
Yo u r v e h i c l e h a s a l s o b e e nequipped with a TPMS malfunctionindicator to indicate when thesystem is not operating properly.The TPMS malfunction indicator iscombined with the low tire pressuretelltale. When the system detects amalfunction, the telltale will flash forapproximately one minute and thenremain continuously illuminated.This sequence will continue uponsubsequent vehicle start-ups aslong as the malfunction exists.
When the malfunction indicator isilluminated, the system may not beable to detect or signal low tirepressure as intended. TPMSmalfunctions may occur for a varietyof reasons, including the installationof replacement or alternate tires orwheels on the vehicle that preventthe TPMS from functioning properly.Always check the TPMS malfunctiontelltale after replacing one or moretires or wheels on your vehicle toensure that the replacement oralternate tires and wheels allow theTPMS to continue to functionproperly.
SeeTire Pressure MonitorOperation0408.
SeeRadio FrequencyStatement0482.
Tire Pressure Monitor
Operation
This vehicle may have a TirePressure Monitor System (TPMS).The TPMS is designed to warn thedriver when a low tire pressurecondition exists. TPMS sensors aremounted onto each tire and wheelassembly, excluding the spare tireand wheel assembly. The TPMSsensors monitor the air pressure inthe tires and transmit the tirepressure readings to a receiverlocated in the vehicle.
When a low tire pressure conditionis detected, the TPMS illuminatesthe low tire pressure warning light

Vehicle Care 409
located on the instrument cluster.If the warning light comes on, stopas soon as possible and inflate thetires to the recommended pressureshown on the Tire and LoadingInformation label. SeeVehicle LoadLimits0259.
AmessagetocheckthepressureinaspecifictiredisplaysintheDriverInformation Center (DIC). The lowtire pressure warning light and theDIC warning message come on ateach ignition cycle until the tires areinflated to the correct inflationpressure. If the vehicle has DICbuttons, tire pressure levels can beviewed. For additional informationand details about the DICoperation and displays, seeDriverInformation Center (DIC) (BaseLevel)0145orDriver InformationCenter (DIC) (Uplevel)0147andTire Messages0157.
The low tire pressure warning lightmay come on in cool weather whenthe vehicle is first started, and thenturn off as the vehicle is driven. Thiscould be an early indicator that the
air pressure is getting low andneeds to be inflated to the properpressure.
ATire and Loading Information labelshows the size of the originalequipment tires and the correctinflation pressure for the tires whenthey are cold. SeeVehicle LoadLimits0259,foranexampleoftheTire and Loading Information labeland its location. Also seeTirePressure0405.
The TPMS can warn about a lowtire pressure condition but it doesnot replace normal tiremaintenance. SeeTire Inspection0411,Tire Rotation0412andTires0397.
Caution
Tire sealant materials are not all
the same. A non-approved tire
sealant could damage the TPMS
sensors. TPMS sensor damage
caused by using an incorrect tire
sealant is not covered by the
vehicle warranty. Always use only

the GM approved tire sealant
available through your dealer or
included in the vehicle.
TPMS Malfunction Light and
Message
The TPMS will not function properlyif one or more of the TPMS sensorsare missing or inoperable. When thesystem detects a malfunction, thelow tire pressure warning lightflashes for about one minute andthen stays on for the remainder ofthe ignition cycle. A DIC warningmessage also displays. Themalfunction light and DIC warningmessage come on at each ignitioncycle until the problem is corrected.Some of the conditions that cancause these to come on are:
.One of the road tires has beenreplaced with the spare tire. Thespare tire does not have aTPMS sensor. The malfunctionlight and the DIC messageshould go off after the road tire

is replaced and the sensormatching process is performedsuccessfully. See "TPMS SensorMatching Process" later in thissection.
.The TPMS sensor matchingprocess was not done or notcompleted successfully afterrotating the tires. Themalfunction light and the DICmessage should go off aftersuccessfully completing thesensor matching process. See"TPMS Sensor MatchingProcess" later in this section.
.One or more TPMS sensors aremissing or damaged. Themalfunction light and the DICmessage should go off when theTPMS sensors are installed andthe sensor matching process isperformed successfully. Seeyour dealer for service.
.Replacement tires or wheels donot match the original equipmenttires or wheels. Tires and wheelsother than those recommended
could prevent the TPMS fromfunctioning properly. SeeBuyingNew Tires0415.
.Operating electronic devices orbeing near facilities using radiowave frequencies similar to theTPMS could cause the TPMSsensors to malfunction.
If the TPMS is not functioningproperly, it cannot detect or signal alow tire condition. See your dealerfor service if the TPMS malfunctionlight and DIC message come onand stay on.
TPMS Sensor Matching
Process
Each TPMS sensor has a uniqueidentification code. The identificationcode needs to be matched to a newtire/wheel position after rotating thevehicle’stiresorreplacingoneormore of the TPMS sensors. Also,the TPMS sensor matching processshould be performed after replacingasparetirewitharoadtirecontaining the TPMS sensor. Themalfunction light and the DIC
message should go off at the nextignition cycle. The sensors arematched to the tire/wheel positions,using a TPMS relearn tool, in thefollowing order: driver side front tire,passenger side front tire, passengerside rear tire, and driver side rear.See your dealer for service or topurchase a relearn tool. A TPMSrelearn tool can also be purchased.See Tire Pressure Monitor SensorActivation Tool atwww.gmtoolsandequipment.com orcall 1-800-GM TOOLS(1-800-468-6657).
There are two minutes to match thefirst tire/wheel position, andfive minutes overall to match all fourtire/wheel positions. If it takeslonger, the matching process stopsand must be restarted.
The TPMS sensor matchingprocess is:
1. Set the parking brake.
2. Turn the ignition to ON/RUNwith the engine off.

Tire Inspection
We recommend that the tires,
including the spare tire, if the
vehicle has one, be inspected
for signs of wear or damage at
least once a month.
Replace the tire if:
.The indicators at three or
more places around the tire
can be seen.
