Driving and Operating 223
{Warning
Wet brakes can cause crashes.
They might not work as well in a
quick stop and could cause
pulling to one side. You could
lose control of the vehicle.
After driving through a large
puddle of water or a car/vehicle
wash, lightly apply the brake
pedal until the brakes work
normally.
Flowing or rushing water creates
strong forces. Driving through
flowing water could cause the
vehicle to be carried away. If this
happens, you and other vehicle
occupants could drown. Do not
ignore police warnings and be
very cautious about trying to drive
through flowing water.
Hydroplaning
Hydroplaning is dangerous. Watercan build up under the vehicle'stires so they actually ride on thewater. This can happen if the road iswet enough and you are going fastenough. When the vehicle ishydroplaning, it has little or nocontact with the road.
There is no hard and fast rule abouthydroplaning. The best advice is toslow down when the road is wet.
Other Rainy Weather Tips
Besides slowing down, other wetweather driving tips include:
.Allow extra following distance.
.Pass with caution.
.Keep windshield wipingequipment in good shape.
.Keep the windshield washer fluidreservoir filled.
.Have good tires with propertread depth. SeeTires0316.
.Turn off cruise control.
Hill and Mountain Roads
Driving on steep hills or throughmountains is different than drivingon flat or rolling terrain. Tips include:
.Keep the vehicle serviced and ingood shape.
.Check all fluid levels and brakes,tires, cooling system, andtransmission.
.Shift to a lower gear when goingdown steep or long hills.
{Warning
Using the brakes to slow the
vehicle on a long downhill slope
can cause brake overheating, can
reduce brake performance, and
could result in a loss of braking.
Shift the transmission to a lower
gear to let the engine assist the
brakes on a steep downhill slope.

.Fuel with a posted octanerating of less than therecommended fuel. Usingthis fuel will lower fueleconomy and performance,and may decrease the life ofthe emissions catalyst.
California Fuel
Requirements
If the vehicle is certified to meetCalifornia Emissions Standards, it isdesigned to operate on fuels thatmeet California specifications. Seethe underhood emission controllabel. If this fuel is not available instates adopting California EmissionsStandards, the vehicle will operatesatisfactorily on fuels meetingfederal specifications, but emission

If it isdetermined that the condition iscaused by the type of fuel used,repairs may not be covered by thevehicle warranty.
Fuels in Foreign
Countries
The U.S., Canada, and Mexico postfuel octane ratings in anti-knockindex (AKI). For fuel not to use in aforeign country, see“ProhibitedFuels”inFuel0266.
Fuel Additives
To k e e p f u e l s y s t e m s c l e a n , T O PTIER®detergent gasoline isrecommended. SeeFuel0266.
If TOP TIER detergent gasoline isnot available, one bottle of GM FuelSystem Treatment Cleaner added tothe fuel tank at every engine oil

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.
