196 Driving and Operating
Using ABS
Do not pump the brakes. Just holdthe brake pedal down firmly and letABS work. You may hear the ABSpump or motor operating and feelthe brake pedal pulsate. This isnormal.
Braking in Emergencies
ABS allows you to steer and brakeat the same time. In manyemergencies, steering can helpmore than even the very bestbraking.
Parking Brake
To s e t t h e p a r k i n g b r a k e , h o l d t h ebrake pedal down and pull up on theparking brake lever. If the ignition ison, the brake system warning lightwill come on. SeeBrake SystemWarning Light011 4.
To r e l e a s e t h e p a r k i n g b r a k e , h o l dthe brake pedal down. Pull theparking brake lever up until you canpress the release button. Hold therelease button in as you move thebrake lever all the way down.
Caution
Driving with the parking brake on
can overheat the brake system
and cause premature wear or
damage to brake system parts.
Make sure that the parking brake
is fully released and the brake
warning light is off before driving.
Brake Assist
The Brake Assist feature isdesigned to assist the driver instopping or decreasing vehiclespeed in emergency drivingconditions. This feature uses thestability system hydraulic brakecontrol module to supplement thepower brake system underconditions where the driver hasquickly and forcefully applied thebrake pedal in an attempt to quicklystop or slow down the vehicle. Thestability system hydraulic brakecontrol module increases brakepressure at each corner of thevehicle until the ABS activates.Minor brake pedal pulsation orpedal movement during this time isnormal and the driver shouldcontinue to apply the brake pedal asthe driving situation dictates. TheBrake Assist feature willautomatically disengage when thebrake pedal is released or brakepedal pressure is quicklydecreased.

Driving and Operating 205
Warning (Continued)
closely, FCA may not provide a
warning with enough time to help
avoid a crash. It also may not
provide any warning at all. FCA
does not warn of pedestrians,
animals, signs, guardrails,
bridges, construction barrels,
or other objects. Be ready to take
action and apply the brakes. See
Defensive Driving0172.
FCA can be disabled with the FCAsteering wheel control.
Detecting the Vehicle Ahead
FCA warnings will not occur unlessthe FCA system detects a vehicleahead. When a vehicle is detected,the vehicle ahead indicator willdisplay green. Vehicles may not be
detected on curves, highway exitramps, or hills, due to poor visibility;or if a vehicle ahead is partiallyblocked by pedestrians or otherobjects. FCA will not detect anothervehicle ahead until it is completelyin the driving lane.
{Warning
FCA does not provide a warning
to help avoid a crash, unless it
detects a vehicle. FCA may not
detect a vehicle ahead if the FCA
sensor is blocked by dirt, snow,
or ice, or if the windshield is
damaged. It may also not detect a
vehicle on winding or hilly roads,
or in conditions that can limit
visibility such as fog, rain,
or snow, or if the headlamps or
windshield are not cleaned or in
proper condition. Keep the
windshield, headlamps, and FCA
sensors clean and in good repair.
Collision Alert
When your vehicle approachesanother detected vehicle too rapidly,the red FCA display on top of theinstrument panel to the right of thesteering wheel will flash. Also,several rapid high-pitched beeps willsound from the front. When thisCollision Alert occurs, the brakesystem may prepare for driverbraking to occur more rapidly whichcan cause a brief, mild deceleration.Continue to apply the brake pedalas needed. Cruise control may bedisengaged when the Collision Alertoccurs.
Tailgating Alert
The red FCA display will staycontinuously illuminated when youare following a detected vehicleahead much too closely.

206 Driving and Operating
Selecting the Alert Timing
The Collision Alert control is on thesteering wheel. Press COLLISIONALERT to set the alert timing to far,medium, near or off. The first buttonpress shows the current controlsetting on the DIC. Additional buttonpresses will change this setting. Thechosen setting will remain until it ischanged and will affect 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 alert
timing. The range of selectable alerttiming may not be appropriate for alldrivers and driving conditions.
Unnecessary Alerts
FCA may sometimes setunnecessary alerts to turningvehicles, vehicles in other lanes,objects that are not vehicles,or shadows. These alerts arenormal operation and the vehicledoes 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 may correct theissue.
Lane Departure
Warning (LDW)
If equipped, LDW may help avoidcrashes due to unintentional lanedepartures. It may provide an alert ifthe vehicle is crossing a lanewithout using a turn signal in thatdirection. LDW uses a camera
sensor to detect the lane markingsat speeds of 56 km/h (35 mph) orgreater.
{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.
If LDW only detects lane
markings on one side of the road,
it will only warn you when

Wheels and Tires
Tires
Every new GM vehicle has
high-quality tires made by a
leading tire manufacturer. See
the warranty manual for
information regarding the tire
warranty and where to get
service. For additional
information refer to the tire
manufacturer.
{Warning
.Poorly maintained and
improperly used tires are
dangerous.
.Overloading the tires can
cause overheating as a
result of too much
flexing. There could be a
blowout and a serious
crash. SeeVehicle Load
Limits0178.

Vehicle Care 267
Caution
The wrong wheel can also cause
problems with bearing life, brake
cooling, speedometer or
odometer calibration, headlamp
aim, bumper height, vehicle
ground clearance, and tire or tire
chain clearance to the body and
chassis.
Used Replacement Wheels
{Warning
Replacing a wheel with a used
one is dangerous. How it has
been used or how far it has been
driven may be unknown. It could
fail suddenly and cause a crash.
When replacing wheels, use a
new GM original equipment
wheel.
Tire Chains
{Warning
Do not use tire chains. There is
not enough clearance. Tire chains
used on a vehicle without the
proper amount of clearance can
cause damage to the brakes,
suspension, or other vehicle
parts. The area damaged by the
tire chains could cause loss of
control and a crash.
Use another type of traction
device only if its manufacturer
recommends it for the vehicle's
tire size combination and road
conditions. Follow that
manufacturer's instructions. To
avoid vehicle damage, drive slow
and readjust or remove the
traction device if it contacts the
vehicle. Do not spin the wheels.
If traction devices are used, install
them on the front tires.
If a Tire Goes Flat
It is unusual for a tire to blow outwhile driving, especially if the tiresare maintained properly. SeeTires0248.Ifairgoesoutofatire,itismuch more likely to leak out slowly.But if there ever is a blowout, hereare a few tips about what to expectand what to do:
If a front tire fails, the flat tirecreates a drag that pulls the vehicletoward that side. Take your foot offthe accelerator pedal and grip thesteering wheel firmly. Steer tomaintain lane position, and thengently brake to a stop, well off theroad, if possible.
Arearblowout,particularlyonacurve, acts much like a skid andmay require the same correction asused in a skid. Stop pressing theaccelerator pedal and steer tostraighten the vehicle. It may bevery bumpy and noisy. Gently braketo a stop, well off the road,if possible.

284 Vehicle Care
Caution
To a v o i d s u r f a c e d a m a g e , d o n o t
use strong soaps, chemicals,
abrasive polishes, cleaners,
brushes, or cleaners that contain
acid on aluminum or
chrome-plated wheels. Use only
approved cleaners. Also, never
drive a vehicle with aluminum or
chrome-plated wheels through an
automatic car wash that uses
silicone carbide tire cleaning
brushes. Damage could occur
and the repairs would not be
covered by the vehicle warranty.
Brake System
Visually inspect brake lines andhoses for proper hook-up, binding,leaks, cracks, chafing, etc. Inspectdisc brake pads for wear and rotorsfor surface condition. Inspect drumbrake linings/shoes for wear orcracks. Inspect all other brake parts.
Steering, Suspension, and
Chassis Components
Visually inspect steering,suspension, and chassiscomponents for damaged, loose,or missing parts or signs of wear atleast once a year.
Inspect power steering for properattachment, connections, binding,leaks, cracks, chafing, etc.
Visually check constant velocity jointboots and axle seals for leaks.
Body Component Lubrication
Lubricate all key lock cylinders,hood hinges, liftgate hinges, and thesteel fuel door hinges, unless thecomponents are plastic. Applyingsilicone grease on weatherstripswith a clean cloth will make themlast longer, seal better, and not stickor squeak.
Underbody Maintenance
At least twice a year, spring and fall,use plain water to flush anycorrosive materials from the
underbody. Take care to thoroughlyclean any areas where mud andother debris can collect.
Do not directly power wash thetransfer case and/or front/rear axleoutput seals. High pressure watercan overcome the seals andcontaminate the fluid. Contaminatedfluid will decrease the life of thetransfer case and/or axles andshould be replaced.
Sheet Metal Damage
If the vehicle is damaged andrequires sheet metal repair orreplacement, make sure the bodyrepair shop applies anti-corrosionmaterial to parts repaired orreplaced to restore corrosionprotection.
Original manufacturer replacementparts will provide the corrosionprotection while maintaining thevehicle warranty.
Finish Damage
Quickly repair minor chips andscratches with touch-up materialsavailable from your dealer to avoid
