204 Driving and Operating
Passing
More passing distance is neededwhen towing a trailer. Thecombination will not accelerate asquickly and is longer so it isnecessary to go much fartherbeyond the passed vehicle beforereturning to the lane.
Backing Up
Hold the bottom of the steeringwheel with one hand. To move thetrailer to the left, move that hand tothe left. To move the trailer to theright, move your hand to the right.Always back up slowly and,if possible, have someoneguide you.
Making Turns
Caution
Making very sharp turns while
trailering could cause the trailer to
come in contact with the vehicle.
The vehicle could be damaged.
Avoid making very sharp turns
while trailering.
When turning with a trailer, makewider turns than normal. Do this sothe trailer will not strike softshoulders, curbs, road signs, trees,or other objects. Avoid jerky orsudden maneuvers. Signal well inadvance.
If the trailer turn signal bulbs burnout, the arrows on the instrumentcluster will still flash for turns. It isimportant to check occasionally tobe sure the trailer bulbs are stillworking.
Driving on Grades
Reduce speed and shift to a lowergearbeforestarting down a long orsteep downgrade. If thetransmission is not shifted down, thebrakes might get hot and no longerwork well.
Vehicles can tow in D (Drive). Shiftthe transmission to a lower gear ifthe transmission shifts too oftenunder heavy loads and/or hillyconditions.
The Tow/Haul Mode may be used ifthe transmission shifts too often.SeeTo w / H a u l M o d e0187.
When towing at high altitude onsteep uphill grades, consider thefollowing: Engine coolant will boil atalowertemperaturethanatnormalaltitudes. If the engine is turned offimmediately after towing at highaltitude on steep uphill grades, thevehicle may show signs similar toengine overheating. To avoid this,let the engine run while parked,preferably on level ground, with thetransmission in P (Park) for a fewminutes before turning the engineoff. If the overheat warning comeson, seeEngine Overheating0230.
Parking on Hills
{Warning
Parking the vehicle on a hill with
the trailer attached can be
dangerous. If something goes
wrong, the rig could start to move.
People can be injured, and both
the vehicle and the trailer can be
damaged. When possible, always
park the rig on a flat surface.

206 Driving and Operating
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.
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”following.
Trailering is different than justdriving the vehicle by itself.Trailering means changes inhandling, 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 of
your passengers. So please readthis section carefully before pulling atrailer.
Weight of the Trailer
Safe trailering requires monitoringthe weight, speed, altitude, roadgrades, outside temperature, andhow frequently the vehicle is used topull a trailer are all important. Takeinto consideration any specialequipment on the vehicle, and theamount of tongue weight the vehiclecan carry. See“Weight of the TrailerTo n g u e”later in this section.
Maximum trailer weight is calculatedassuming only the driver is in thetow vehicle and it has all therequired trailering equipment. Theweight of additional optionalequipment, passengers,and cargo inthe tow vehicle must be subtractedfrom the maximum trailer weight.
Use the following chart to determinehow much the vehicle can weigh,based upon the vehicle model andoptions.

the 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 recommendedcould prevent the TPMS fromfunctioning properly. SeeBuyingNew Tires0268.
.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’stiresorreplacingoneor
more of the TPMS sensors. Also,the TPMS sensor matching processshould be performed after replacingasparetirewitharoadtirecontaining the TPMS sensor. Themalfunction light and the DICmessage 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.
3. Press the Remote Keyless
Entry (RKE) transmitter'sQ
andKbuttons at the same
time for approximatelyfive seconds. The horn soundstwice to signal the receiver is inrelearn mode and TIRELEARNING ACTIVE messagedisplays on the DIC screen.
If the vehicle does not haveRKE, press the DriverInformation Center (DIC)vehicle information button untilthe PRESSVTO RELEARNTIRE POSITIONS messagedisplays. The horn soundstwice to signal the receiver is inrelearn mode and TIRELEARNING ACTIVE messagedisplays on the DIC screen.
4. Start with the driver sidefront tire.

chains on the tires of the front
axle. Tighten them as tightly as
possible with the ends securely
fastened. Drive slowly and follow
the chain manufacturer's
instructions. If the chains contact
the vehicle, stop and retighten
them. If the contact continues,
slow down until it stops. Driving
too fast or spinning the wheels
with chains on will damage the
vehicle.
For Cutaway models with LT245/75R16, LT225/75R16 or LT215/85R16 size single or dual rear tires,use Low Profile Z-Chain or SAEClass S cables.

If the vehicle has dual rear tires, donot use individual tire chains. Usetire chains that fit across both dualtires.
If a Tire Goes Flat
It is unusual for a tire to blow outwhile driving, especially if the tiresare maintained properly. SeeTires0252.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 be
very bumpy and noisy. Gently braketo a stop, well off the road,if possible.
{Warning
Driving on a flat tire will cause
permanent damage to the tire.
Re-inflating a tire after it has been
driven on while severely
underinflated or flat may cause a
blowout and a serious crash.
Never attempt to re-inflate a tire
that has been driven on while
severely underinflated or flat.
Have your dealer or an authorized
tire service center repair or
replace the flat tire as soon as
possible.

Managing the Vehicle Damage
Repair Process
In the event that the vehicle requiresdamage repairs, GM recommendsthat you take an active role in itsrepair. If you have a pre-determinedrepair facility of choice, take thevehicle there, or have it towed there.Specify to the facility that anyrequired replacement collision partsbe original equipment parts, eithernew Genuine GM parts or recycled
original GM parts. Remember,recycled parts will not be covered bythe GM vehicle warranty.
Insurance pays the bill for the repair,but you must live with the repair.Depending on your policy limits,your insurance company mayinitially value the repair usingaftermarket parts. Discuss this withthe repair professional, and insist onGenuine GM parts. Remember,if the vehicle is leased, you may beobligated to have the vehiclerepaired with Genuine GM parts,even if your insurance coveragedoes not pay the full cost.
If another party's insurancecompany is paying for the repairs,you are not obligated to accept arepair valuation based on thatinsurance company's collision policyrepair limits, as you have nocontractual limits with that company.In such cases, you can have controlof the repair and parts choices aslong as the cost stays withinreasonable limits.
