Lighting Features
Entry Lighting
Some exterior lamps and the interiorlamps turn on briefly at night, or in
areas with limited lighting, whenK
is pressed on the Remote KeylessEntry (RKE) transmitter. When adoor is opened, the interior lampscome on if the dome lamp control isin the DOOR position. After about30 seconds the exterior lamps turnoff. Entry lighting can be disabledmanually by changing the ignitionout of the OFF position, or by
pressing the RKE transmitterQ
button.
This feature can be changed. See“Ve h i c l e L o c a t o r L i g h t s”underVehicle Personalization0160.
Exit Lighting
Some exterior lamps and the interiorlamps come on at night, or in areaswith limited lighting when the key isremoved from the ignition. Theexterior and interior lamps remainon for a set amount of time and then
automatically turn off. The interiorlamps do not come on if the domelamp control is in the Off position.
The exterior lamps turn offimmediately by turning the exteriorlamps control off.
This feature can be changed. SeeVehicle Personalization0160.
Battery Load
Management
The vehicle has Electric PowerManagement (EPM), whichestimates the battery's temperatureand state of charge. It then adjuststhe voltage for best performanceand extended life of the battery.
When the battery's state of chargeis low, the voltage is raised slightlyto quickly bring the charge back up.When the state of charge is high,the voltage is lowered slightly toprevent overcharging. The voltmetergauge or the voltage display on theDriver Information Center (DIC),if equipped, may show the voltage
moving up or down. This is normal.If there is a problem, an alert will bedisplayed.
The battery can be discharged atidle if the electrical loads are veryhigh. This is true for all vehicles.This is because the generator(alternator) may not be spinning fastenough at idle to produce all thepower that is needed for very highelectrical loads.
Ahighelectricalloadoccurswhenseveral of the following are on, suchas: headlamps, high beams, foglamps, rear window defogger,climate control fan at high speed,heated seats, engine cooling fans,trailer loads, and loads plugged intoaccessory power outlets.
EPM works to prevent excessivedischarge of the battery. It does thisby balancing the generator's outputand the vehicle's electrical needs.It can increase engine idle speed togenerate more power, wheneverneeded. It can temporarily reducethe power demands of someaccessories.

248 Driving and Operating
Refer to the infotainment section formore information on using thatsystem and the navigation system,if equipped, including pairing andusing a cell phone.
Defensive Driving
Defensive driving means“alwaysexpect the unexpected.”The firststep in driving defensively is to wearthe safety belt. SeeSafetyBelts066.
.Assume that other road users(pedestrians, bicyclists, andother drivers) are going to becareless and make mistakes.Anticipate what they might doand be ready.
.Allow enough following distancebetween you and the driver infront of you.
.Focus on the task of driving.
Drunk Driving
Death and injury associated withdrinking and driving is a globaltragedy.
{Warning
Drinking and then driving is very
dangerous. Your reflexes,
perceptions, attentiveness, and
judgment can be affected by even
asmallamountofalcohol.You
can have a serious—or even
fatal—collision if you drive after
drinking.
Do not drink and drive or ride with
adriverwhohasbeendrinking.
Ride home in a cab; or if you are
with a group, designate a driver
who will not drink.
Control of a Vehicle
Braking, steering, and acceleratingare important factors in helping tocontrol a vehicle while driving.
Braking
Braking action involves perceptiontime and reaction time. Deciding topush the brake pedal is perceptiontime. Actually doing it isreaction time.
Average driver reaction time isabout three-quarters of a second. Inthat time, a vehicle moving at100 km/h (60 mph) travels 20 m(66 ft), which could be a lot ofdistance in an emergency.
Helpful braking tips to keep in mindinclude:
.Keep enough distance betweenyou and the vehicle in frontof you.
.Avoid needless heavy braking.
.Keep pace with traffic.
If the engine ever stops while thevehicle is being driven, brakenormally but do not pump thebrakes. Doing so could make thepedal harder to push down. If theengine stops, there will be somepower brake assist but it will beused when the brake is applied.Once the power assist is used up, itcan take longer to stop and thebrake pedal will be harder to push.

Steering
Electric Power Steering (1500
Series)
If the vehicle has electric powersteering, it does not have powersteering fluid. Regular maintenanceis not required.
If power steering assist is lost dueto a system malfunction, the vehiclecan be steered, but may requireincreased effort. See your dealer ifthere is a problem.
If the steering wheel is turned until itreaches the end of its travel, and isheld in that position for an extendedperiod of time, power steering assistmay be reduced.
If the steering assist is used for anextended period of time, powerassist may be reduced.
Normal use of the power steeringassist should return when thesystem cools down.
See specific vehicle steeringmessages underSteering SystemMessages0156.
Hydraulic Power Steering
(2500/3500 Series)
(2500/3500 Series–All RegularCab, Double Cab/Crew Cabwithout Digital Steer Assist)
The power steering system mayrequire maintenance. SeePowerSteering Fluid (1500 Series)0375orPower Steering Fluid (2500/3500Series)0375.
If power steering assist is lostbecause the engine stops or thesystem malfunctions, the vehiclecan be steered but may requireincreased effort. See your dealer.
(2500/3500 Series–Double Cab/Crew Cab with Digital SteerAssist)
The vehicle has a Digital SteerAssist power steering system thatvaries the amount of effort requiredto steer the vehicle. Less steeringeffort is required at slower speeds.At faster speeds, the steering effortincreases. The system helps thesteering wheel return to center atlow speeds. Pressing the Tow/Haul
button adjusts steering effort fordriving conditions described inTo w /Haul Mode0282.
The power steering system mayrequire maintenance. SeePowerSteering Fluid (1500 Series)0375orPower Steering Fluid (2500/3500Series)0375.
If power steering assist is lostbecause the engine stops or thesystem malfunctions, the vehiclecan be steered but may requireincreased effort. See your dealer.
Caution
If the steering wheel is turned
until it reaches the end of its
travel, and is held in that position
for more than 15 seconds,
damage may occur to the power
steering system and there may be
loss of power steering assist.

Driving and Operating 251
The vehicle may straighten out.Be ready for a second skid if itoccurs.
.Slow down and adjust yourdriving according to weatherconditions. Stopping distancecan be longer and vehiclecontrol can be affected whentraction is reduced by water,snow, ice, gravel, or othermaterial on the road. Learn torecognize warning clues—suchas enough water, ice, or packedsnow on the road to make amirrored surface—and slowdown when you have any doubt.
.Try to avoid sudden steering,acceleration, or braking,including reducing vehicle speedby shifting to a lower gear. Anysudden changes could causethe tires to slide.
Remember: Antilock brakes helpavoid only the braking skid.
Off-Road Driving
Four-wheel-drive vehicles can beused for off-road driving. Vehicleswithout four-wheel drive and
vehicles not equipped with AllTe r r a i n ( AT ) o r O n - O f f R o a d ( O O R )tires must not be driven off-roadexcept on a level, solid surface. Forcontact information about theoriginal equipment tires, see thewarranty manual.
One of the best ways for successfuloff-road driving is to control thespeed.
{Warning
When driving off-road, bouncing
and quick changes in direction
can easily throw you out of
position. This could cause you to
lose control and crash. You and
your passengers should always
wear safety belts.
Before Driving Off-Road
.Have all necessary maintenanceand service work completed.
.Fuel the vehicle, fill fluid levels,and check inflation pressure inall tires, including the spare,if equipped.
.Read all the information aboutfour-wheel-drive vehicles in thismanual.
.Remove any underbody airdeflector, if equipped. Re-attachthe air deflector after off-roaddriving.
.SeeHill Descent Control(HDC)0297
.Know the local laws that apply tooff-road driving.
To g a i n m o r e g r o u n d c l e a r a n c e i fneeded, it may be necessary toremove the front fascia lower airdam. However, driving without theair dam reduces fuel economy.
Caution
Operating the vehicle for
extended periods without the front
fascia lower air dam installed can
cause improper airflow to the
engine. Reattach the front fascia
air dam after off-road driving.

{Warning
Driving to the top of a hill at high
speed can cause an accident.
There could be a drop-off,
embankment, cliff, or even
another vehicle. You could be
seriously injured or killed. As you
near the top of a hill, slow down
and stay alert.
.Never go downhill forward orbackward with either thetransmission or transfer case inN(Neutral).Thebrakescouldoverheat and you could losecontrol.
{Warning
If the vehicle has the two⇣speed
automatic transfer case, shifting
the transfer case to N (Neutral)
can cause your vehicle to roll
even if the transmission is in
P(Park).Thisisbecausethe

transfer case overrides the
transmission. You or someone
else could be injured. If leaving
the vehicle, set the parking brake
and shift the transmission to
P(Park).Shiftthetransfercaseto
any position but N (Neutral).
.When driving down a hill, keepthe vehicle headed straightdown. Use a low gear becausethe engine will work with thebrakes to slow the vehicle andhelp keep the vehicle undercontrol.
{Warning
Heavy braking when going down
ahillcancauseyourbrakesto
overheat and fade. This could
cause loss of control and you or
others could be injured or killed.

descending a hill and use a low
gear to keep vehicle speed under
control.
If the vehicle stalls on a hill:
1. Apply the brakes to stop thevehicle, and then apply theparking brake.
2. Shift into P (Park) and thenrestart the engine.
.If driving uphill when thevehicle stalls, shift toR(Reverse),releasetheparking brake, and backstraight down.
.Never try to turn the vehiclearound. If the hill is steepenough to stall the vehicle,it is steep enough to causeit to roll over.
.If you cannot make it up thehill, back straight downthe hill.

256 Driving and Operating
{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. SeeTires0397.
.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.
