If the LDW system is not functioningproperly when lane markings areclearly visible, cleaning thewindshield may help.
LDW alerts may occur due to tarmarks, shadows, cracks in the road,temporary or construction lanemarkings, or other roadimperfections. This is normal systemoperation; the vehicle does not needservice. Turn LDW off if theseconditions continue.
Lane Keep Assist (LKA)
(1500 Series)
If equipped, LKA may help avoidcrashes due to unintentional lanedepartures. It may assist by gentlyturning the steering wheel if thevehicle approaches a detected lanemarking without using a turn signalin that direction. It may also provideaLaneDepartureWarning(LDW)system alert as the lane marking iscrossed. The LKA system will notassist or provide an LDW alert if itdetects that you are activelysteering. Override LKA by turningthe steering wheel. LKA uses a
camera to detect lane markingsbetween 60 km/h (37 mph) and180 km/h (112 mph).
{Warning
The LKA system does not
continuously steer the vehicle.
It may not keep the vehicle in the
lane or give a Lane Departure
Warning (LDW) alert, even if a
lane marking is detected.
The LKA and LDW systems
may not:
.Provide an alert or enoughsteering assist to avoid alane departure or 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.
(Continued)
Warning (Continued)
.Detect lanes on winding orhilly roads.
If LKA only detects lane markings
on one side of the road, it will
only assist or provide an LDW
alert when approaching the lane
on the side where it has detected
alanemarking.EvenwithLKA
and LDW, you must steer the
vehicle. Always keep your
attention on the road and
maintain proper vehicle position
within the lane, or vehicle
damage, injury, or death could
occur. Always keep the
windshield, headlamps, and
camera sensors clean and in
good repair. Do not use LKA in
bad weather conditions.

selection 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.
Integrated Trailer Brake
Control System
The vehicle may have an IntegratedTrailer Brake Control (ITBC) systemfor use with electric trailer brakes ormost electric over hydraulic trailerbrakes.
This symbol is on the Trailer BrakeControl Panel on vehicles with anITBC system. The power output tothe trailer brakes is based on theamount of brake pressure beingapplied by the vehicle’sbrake
system, and on the type of trailerbrakes detected. This availablepower output to the trailer brakescan be adjusted to a wide range oftrailering situations.
The ITBC system is integrated withthe vehicle’sbrake,antilockbrake,and StabiliTrak systems. In traileringconditions that cause the vehicle’santilock brake or StabiliTraksystems to activate, power sent tothe trailer's brakes will beautomatically adjusted to minimizetrailer wheel lock-up. This does notimply that the trailer has StabiliTrak.
If the vehicle’sbrake,antilockbrake,or StabiliTrak systems are notfunctioning properly, the ITBCsystem may not be fully functionalor may not function at all. Make sureall of these systems are fullyoperational to ensure fullfunctionality of the ITBC system.
The ITBC system is poweredthrough the vehicle's electricalsystem. Turning the ignition off willalso turn off the ITBC system. TheITBC system is fully functional onlywhen the ignition is in ON/RUN.
{Warning
Connecting a trailer that has an
air brake system may result in
reduced or complete loss of trailer
braking. There may be an
increase in stopping distance or
trailer instability which could
result in personal injury or
damage to the vehicle, trailer,
or other property. Use the ITBC
system only with electric or
electric over hydraulic trailer
brakes.

.There is a fault present in thewiring to the trailer brakes (aCHECK TRAILER WIRINGmessage will also display onthe DIC).
.The ITBC system is not workingdue to a fault (a SERVICETRAILER BRAKE SYSTEMmessage will also display inthe DIC).
Manual Trailer Brake Apply
The Manual Trailer Brake ApplyLever is used to apply the trailer’selectric brakes independent of thevehicle’sbrakes.Slidingthelevertothe left will apply only the trailerbrakes. Use this lever to adjustTrailer Gain to properly adjust thepower output to the trailer brakes.
The trailer's and the vehicle's brakelamps will come on when eithervehicle brakes or manual trailerbrakes are applied.
Trailer Gain Adjustment Procedure
Trailer Gain should be set for aspecific trailering condition and mustbe adjusted anytime vehicle loading,trailer loading, or road surfaceconditions change.
{Warning
Trailer brakes that are
over-gained or under-gained may
not stop the vehicle and the trailer
as intended and can result in a
crash. Always follow the
instructions to set the Trailer Gain
for the proper trailer stopping
performance.
Use the following to adjust TrailerGain for each towing condition:
1. Drive the vehicle with the trailerattached on a level roadsurface representative of thetowing condition and free oftraffic at about 32 to 40 km/h(20 to 25 mph) and fully applythe Manual Trailer Brake ApplyLever.
Adjusting Trailer Gain atspeeds lower than 32 to40 km/h (20 to 25 mph) mayresult in an incorrect gainsetting.
2. Adjust the Trailer Gain, usingthe Trailer Gain AdjustmentButtons, to just below the pointof trailer wheel lock-up,indicated by trailer wheelsqueal or tire smoke when atrailer wheel locks.
Trailer wheel lock-up may notoccur if towing a heavily loadedtrailer. In this case, adjust theTrailer Gain to the highestallowable setting for the towingcondition.
3. Readjust Trailer Gain anytimevehicle loading, trailer loading,or road surface conditionschange or if trailer wheellock-up is noticed at any timewhile towing.

damaged if either the front or rear
axle ratings or the Gross Vehicle
Weight Rating (GVWR) are
exceeded.
The plow the vehicle can carrydepends on many things, such as:
.The options the vehicle camewith, and the weight of thoseoptions.
.The weight and number ofpassengers to be carried.
.The weight of items added to thevehicle, like a tool box ortruck cap.
.The total weight of anyadditional cargo to be carried.
For example, if the snow plowweighs 318 kg (700 lb), the totalweight of all occupants and cargoinside the cab should not exceed135 kg (300 lb). This means that youmay only be able to carry onepassenger. Even this may be too
much if there is other equipmentalready adding to the weight of thevehicle.
To s a f e l y c a r r y a s n o w p l o w o n t h evehicle:
.Follow all aftermarket snow plowmanufacturer’sinstructionsforthe operation and transportationof the snow plow.
.With a snow plow attached, theengine coolant temperaturegauge may show a highertemperature than while drivingwithout one. The snow plowcould block the airflow to theradiator. This could be morenoticeable as vehicle speedincreases. At speeds above72 km (45 mph), this may causethe engine coolant to overheat.
.To i n c r e a s e t h e a i r f l o w, m o v e t h esnow plow blade postion.
.If driving more than 24 km(15 mi), angle the plow bladeposition.
.Make sure the weight on thefront and rear axles does notexceed the axle rating for each.
.For the front axle, if more cargoor passengers must be carried,appropriate counter ballast mustbe installed rear of the rear axle.Counter ballast must be properlysecured so it will not moveduring driving.
.Rear ballast may be required toensure a proper front and rearweight distribution ratio, eventhough the actual weight at thefront axle may be less than thefront axle rating.
.The snow plow manufacturer orinstaller can assist indetermining the amount of rearballast required, to help makesure the snow plow/vehiclecombination does not exceedthe GVW rating, the front andrear axle ratings, and the frontand rear weight distribution ratio.
.The total vehicle must notexceed the GVW rating.

6. Perform a hot check at the firstopportunity after thetransmission reaches a normaloperating temperature between71 °C to 93 °C (160 °F to200 °F).
7. If the fluid level is in theacceptable range, push thedipstick back in all the way,then flip the handle down tolock the dipstick in place.
Hot Check Procedure
Use this procedure to check thetransmission fluid level when thetransmission fluid temperature isbetween 71 °C and 93 °C (160 °Fand 200 °F).
The hot check is the most accuratemethod to check the fluid level. Thehot check should be performed atthe first opportunity in order to verifythe cold check. The fluid level risesas fluid temperature increases, so itis important to ensure thetransmission temperature is withinrange.
1. Locate the transmissiondipstick at the rear of theengine compartment, on thepassenger side of the vehicle.
SeeEngine CompartmentOverview0354.
2. Flip the handle up, then pull outthe dipstick and wipe it with aclean rag or paper towel.
3. Install the dipstick by pushing itback in all the way; waitthree seconds, and then pull itback out again.
4. Check both sides of thedipstick and read the lowerlevel. Repeat the checkprocedure to verify the reading.
5. Safe operating level is withinthe HOT cross hatch band onthe dipstick. If the fluid level isnot within the HOT band, andthe transmission temperature isbetween 71 °C and 93 °C(160 °F and 200 °F), add ordrain fluid as necessary tobring the level into the HOTband. If the fluid level is low,add only enough fluid to bringthe level into the HOT band.It does not take much fluid,generally less than 0.5 L (1 pt).Do not overfill.
6. If the fluid level is in theacceptable range, push thedipstick back in all the way,then flip the handle down tolock the dipstick in place.
