Operating the vehicle in Tow/Haulwhen lightly loaded or with no trailerat all will not cause damage.However, there is no benefit to theselection of Tow/Haul when thevehicle is unloaded. Such aselection when unloaded may resultin unpleasant engine andtransmission driving characteristicsand reduced fuel economy. Tow/Haul is recommended only whenpulling a heavy trailer or a large orheavy load.
If the vehicle has a diesel engine,the Tow/Haul button activates theexhaust brake systemsimultaneously. See“ExhaustBrake”in the Duramax dieselsupplement.
Trailer Sway
Control (TSC)
Vehicles with StabiliTrak have aTrailer Sway Control (TSC) feature.Trailer sway is unintendedside-to-side motion of a trailer whilebeing towed. If the vehicle is towingatrailerandtheTSCdetectsthatsway is increasing, the vehiclebrakes are selectively applied ateach wheel, to help reduceexcessive trailer sway. If the vehicleis equipped with the IntegratedTrailer Brake Control (ITBC) system,and the trailer has the electricactuated brake system, StabiliTrakmay also apply the trailer brakes.
If TSC is enabled, the TractionControl System (TCS)/StabiliTrakwarning light will flash on theinstrument cluster. Vehicle speedmust be reduced. If trailer swaycontinues, StabiliTrak can reduceengine torque to help slow thevehicle. SeeTr a c t i o n C o n t r o l /Electronic Stability Control0256.

Even if the vehicle is equipped
with TSC, trailer sway could result
in loss of control and the vehicle
could crash. If excessive trailer
sway is detected, slow down to a
safe speed. Check the trailer and
vehicle to help correct possible
causes. These could include an
improperly or overloaded trailer,
unrestrained cargo, improper
trailer hitch configuration,
excessive vehicle-trailer speed,
or improperly inflated or incorrect
vehicle or trailer tires. SeeTo w i n g

heard all the time the vehicle ismoving, except when applying thebrake pedal firmly.
{Warning
The brake wear warning sound
means that soon the brakes will
not work well. That could lead to
acrash.Whenthebrakewear
warning sound is heard, have the
vehicle serviced.
Caution
Continuing to drive with worn-out
brake pads could result in costly
brake repair.
Some driving conditions or climatescan cause a brake squeal when thebrakes are first applied or lightlyapplied. This does not meansomething is wrong with the brakes.
Properly torqued wheel nuts arenecessary to help prevent brakepulsation. When tires are rotated,inspect brake pads for wear andevenly tighten wheel nuts in theproper sequence to torquespecifications inCapacities andSpecifications0380.
Brake linings should always bereplaced as complete axle sets.
Brake Pedal Travel
See your dealer if the brake pedaldoes not return to normal height,or if there is a rapid increase inpedal travel. This could be a signthat brake service may be required.
Replacing Brake System Parts
Always replace brake system partswith new, approved replacementparts. If this is not done, the brakesmay not work properly. The brakingperformance expected can changein many other ways if the wrongreplacement brake parts areinstalled or parts are improperlyinstalled.
Brake Fluid
The brake/clutch master cylinderreservoir is filled with GM approvedDOT 3 brake fluid as indicated onthe reservoir cap. SeeEngineCompartment Overview0283forthe location of the reservoir.
Checking Brake Fluid
Place the vehicle in P (Park) orNeutral with the parking brakeapplied if equipped with a manualtransmission. On a level surface,the brake fluid level should bebetween the minimum andmaximum marks on the brake fluidreservoir.

300 Vehicle Care
There are only two reasons why thebrake fluid level in the reservoir maygo down:
.Normal brake lining wear. Whennew linings are installed, thefluid level goes back up.
.Afluidleakinthebrake/clutchhydraulic system. Have thebrake/clutch hydraulic systemfixed. With a leak, the brakes willnot work well.
Always clean the brake fluidreservoir cap and the area aroundthe cap before removing it.
Do not top off the brake/clutch fluid.Adding fluid does not correct a leak.If fluid is added when the linings areworn, there will be too much fluidwhen new brake linings areinstalled. Add or remove fluid, asnecessary, only when work is doneon the brake/clutch hydraulicsystem.
{Warning
If too much brake fluid is added, it
can spill on the engine and burn,
if the engine is hot enough. You
or others could be burned, and
the vehicle could be damaged.
Add brake fluid only when work is
done on the brake/clutch
hydraulic system.
When the brake/clutch fluid falls to alow level, the brake warning lightcomes on. SeeBrake SystemWarning Light0120.
Brake fluid absorbs water over timewhich degrades the effectiveness ofthe brake fluid. Replace brake fluidat the specified intervals to preventincreased stopping distance. SeeMaintenance Schedule0366.
What to Add
Use only GM approved DOT 3brake fluid from a clean, sealedcontainer. SeeRecommendedFluids and Lubricants0375.
{Warning
The wrong or contaminated brake
fluid could result in damage to the
brake system. This could result in
the loss of braking leading to a
possible injury. Always use the
proper GM approved brake fluid.
Caution
If brake fluid is spilled on the
vehicle's painted surfaces, the
paint finish can be damaged.
Immediately wash off any painted
surface.

For diesel engine vehicles, see“Battery”in the Duramax dieselsupplement.
The original equipment battery ismaintenance free. Do not removethe cap and do not add fluid.
