Warning (Continued)
Ask your dealer for advice and
information about towing a trailer
with the vehicle.
Caution
Pulling a trailer improperly can
damage the vehicle and result in
costly repairs not covered by the
vehicle warranty. To pull a trailer
correctly, follow the advice in this
section and see your dealer for
important information about
towing a trailer with the vehicle.
SeeVehicle Load Limits0226formore information about the vehicle'smaximum load capacity.
To i d e n t i f y t h e t r a i l e r i n g c a p a c i t y o fthe vehicle, read the information in“Weight of the Trailer”later in thissection.
Trailering is different than justdriving the vehicle by itself.Trailering means changes in
handling, acceleration, braking,durability, and fuel economy.Successful, safe trailering takescorrect equipment, and it has to beused properly.
The following information has manytime-tested, important trailering tipsand safety rules. Many of these areimportant for your safety and that ofyour passengers. Read this sectioncarefully before pulling a trailer.
Weight of the Trailer
How heavy can a trailer safely be?
It depends on how the rig is used.Speed, altitude, road grades,outside temperature, and how muchthe vehicle is used to pull a trailerare all important. It can depend onany special equipment on thevehicle, and the amount of tongueweight the vehicle can carry. See“Weight of the Trailer Tongue”laterin this section for more information.
Trailer Weight Rating (TWR) iscalculated assuming the tow vehiclehas only the driver but all requiredtrailering equipment. Weight ofadditional optional equipment,
passengers, and cargo in the towvehicle must be subtracted from thetrailer weight rating.
Use the following chart to determinehow much the vehicle can weigh,based upon the vehicle model andoptions.

Press this button on the centerstack to turn on and off the Tow/Haul Mode.
This indicator light on the instrumentcluster comes on when the Tow/Haul Mode is on.
To w / H a u l i s a f e a t u r e t h a t a s s i s t swhen pulling a heavy trailer or alarge or heavy load. SeeTo w / H a u lMode0245.
To w / H a u l i s d e s i g n e d t o b e m o s teffective when the vehicle andtrailer combined weight is at least75 percent of the vehicle's GrossCombined Weight Rating (GCWR).See“Weight of the Trailer”underTr a i l e r To w i n g0272.Tow/Haulismost useful under the followingdriving conditions:
.When pulling a heavy trailer or alarge or heavy load throughrolling terrain.
.When pulling a heavy trailer or alarge or heavy load instop-and-go traffic.
.When pulling a heavy trailer or alarge or heavy load in busyparking lots where improved lowspeed control of the vehicle isdesired.
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.

Vehicle Care 297
Warning (Continued)
Wait until there is no sign of
steam or coolant before you open
the hood.
If you keep driving when the
engine is overheated, the liquids
in it can catch fire. You or others
could be badly burned. Stop the
engine if it overheats, and get out
of the vehicle until the engine
is cool.
If No Steam Is Coming from
the Engine Compartment
If an engine overheat warning isdisplayed but no steam can be seenor heard, the problem may not betoo serious. Sometimes the enginecan get a little too hot when thevehicle:
.Climbs a long hill on a hot day.
.Stops after high-speed driving.
.Idles for long periods in traffic.
If the overheat warning is displayedwith no sign of steam:
1. Turn the air conditioning off.
2. Turn the heater on to thehighest temperature and to thehighest fan speed. Open thewindows as necessary.
3. When it is safe to do so, pull offthe road, shift to P (Park) orN(Neutral),andlettheengine idle.
If the engine coolant temperaturegauge is no longer in the overheatzone, the vehicle can be driven.Continue to drive the vehicle slowlyfor about 10 minutes. Keep a safedistance from the vehicle in front.If the warning does not come backon, continue to drive normally andhave the cooling system checkedfor proper fill and function.
If the warning continues, pull over,stop, and park the vehicleright away.
If there is no sign of steam, idle theengine for three minutes whileparked. If the warning is stilldisplayed, turn off the engine until itcools down.
Engine Fan
If the vehicle has a clutched enginecooling fan, when the clutch isengaged, the fan spins faster toprovide more air to cool the engine.In most everyday driving conditions,the fan is spinning slower and theclutch is not fully engaged. Thisimproves fuel economy and reducesfan noise. Under heavy vehicleloading, trailer towing, and/or highoutside temperatures, the fan speedincreases as the clutch more fullyengages, so an increase in fannoise may be heard. This is normaland should not be mistaken as thetransmission slipping or makingextra shifts. It is merely the coolingsystem functioning properly. The fanwill slow down when additionalcooling is not required and theclutch disengages.
This fan noise may also be heardwhen starting the engine. It will goaway as the fan clutch partiallydisengages.
If the vehicle has electric coolingfan(s), the fans may be heardspinning at low speed during most

(3) Aspect Ratio:Atwo-digit
number that indicates the tire
height-to-width measurements.
For example, if the tire size
aspect ratio is 60, as shown in
item 3 of the illustration, it would
mean that the tire's sidewall is
60 percent as high as it is wide.
(4) Construction Code:Aletter
code is used to indicate the type
of ply construction in the tire.
The letter R means radial ply
construction; the letter D means
diagonal or bias ply
construction; and the letter B
means belted-bias ply
construction.
(5) Rim Diameter:Diameter of
the wheel in inches.
(6) Service Description:These
characters represent the load
index and speed rating of the
tire. The load index represents
the load carrying capacity a tire
is certified to carry. The speed
rating is the maximum speed a
tire is certified to carry a load.
Tire Terminology and
Definitions
Air Pressure:The amount of
air inside the tire pressing
outward on each square inch of
the tire. Air pressure is
expressed in kPa (kilopascal)
or psi (pounds per square inch).
Accessory Weight:The
combined weight of optional
accessories. Some examples of
optional accessories are
automatic transmission, power
windows, power seats, and air
conditioning.
Aspect Ratio:The relationship
of a tire's height to its width.
Belt:Arubbercoatedlayerof
cords between the plies and the
tread. Cords may be made from
steel or other reinforcing
materials.
Bead:The tire bead contains
steel wires wrapped by steel
cords that hold the tire onto
the rim.
Bias Ply Tire:Apneumatictire
in which the plies are laid at
alternate angles less than
90 degrees to the centerline of
the tread.
Cold Tire Pressure:The
amount of air pressure in a tire,
measured in kPa (kilopascal)
or psi (pounds per square inch)
before a tire has built up heat
from driving. SeeTire
Pressure0323.
Curb Weight:The weight of a
motor vehicle with standard and
optional equipment including the
maximum capacity of fuel, oil,
and coolant, but without
passengers and cargo.
DOT Markings:Acodemolded
into the sidewall of a tire
signifying that the tire is in
compliance with the U.S.

324 Vehicle Care
Caution
Neither tire underinflation nor
overinflation is good.
Underinflated tires, or tires
that do not have enough air,
can result in:
.Tire overloading and
overheating which could
lead to a blowout.
.Premature or
irregular wear.
.Poor handling.
.Reduced fuel economy.
Overinflated tires, or tires that
have too much air, can
result in:
.Unusual wear.
.Poor handling.
.Rough ride.
.Needless damage from
road hazards.
The Tire and Loading
Information label on the vehicle
indicates the original equipment
tires and the correct cold tire
inflation pressures. The
recommended pressure is the
minimum air pressure needed to
support the vehicle's maximum
load carrying capacity. See
Vehicle Load Limits0226.
How the vehicle is loaded
affects vehicle handling and ride
comfort. Never load the vehicle
with more weight than it was
designed to carry.
When to Check
Check the tires once a month or
more. Do not forget to check the
spare tire. If the vehicle has a
compact spare tire, it should be
at 420 kPa (60 psi). See
Compact Spare Tire0346and
Full-Size Spare Tire0347for
additional information.
How to Check
Use a good quality pocket-type
gauge to check tire pressure.
Proper tire inflation cannot be
determined by looking at the tire.
Check the tire inflation pressure
when the tires are cold, meaning
the vehicle has not been driven
for at least three hours or no
more than 1.6 km (1 mi).
Remove the valve cap from the
tire valve stem. Press the tire
gauge firmly onto the valve to
get a pressure measurement.
If the cold tire inflation pressure
matches the recommended
pressure on the Tire and
Loading Information label, no
further adjustment is necessary.
If the inflation pressure is low,
add air until the recommended
pressure is reached. If the
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.

Vehicle Care 325
Return the valve caps on the
valve stems to prevent leaks
and keep out dirt and moisture.
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.)
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 is
combined 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.
