Reading Lamps
If equipped with reading lamps,press the button next to each lampto turn it on or off.
The vehicle may also have readinglamps in other locations. The lampscannot be adjusted.
Lighting Features
Entry/Exit Lighting
The vehicle has an illuminatedentry/exit feature.
The dome lamps come on if theE
DOME OFF button is in theextended position, when a door isopened, or the key is removed fromthe ignition.
Battery Load
Management
The vehicle may have ElectricPower Management (EPM) thatestimates 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. If the vehiclehas a voltmeter gauge or a voltagedisplay on the Driver Information
Center (DIC), you may see thevoltage move up or down. This isnormal. If there is a problem, analert will be displayed.
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.

Normally, these actions occur insteps or levels, without beingnoticeable. In rare cases at thehighest levels of corrective action,this action may be noticeable to thedriver. If so, a Driver InformationCenter (DIC) message might bedisplayed, such as SERVICEBATTERY CHARGING SYSTEM.If this messages displays, it isrecommended that the driver reducethe electrical loads as much aspossible. SeeBattery Voltage andCharging Messages011 2.
Battery Power Protection
This feature shuts off the domelamps if they are left on for morethan 10 minutes when the ignition isin LOCK/OFF. This helps to preventthe battery from running down.

168 Driving and Operating
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.
Driving on Wet Roads
Rain and wet roads can reducevehicle traction and affect yourability to stop and accelerate.Always drive slower in these typesof driving conditions and avoiddriving through large puddles anddeep-standing or flowing water.
{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
(Continued)
Warning (Continued)
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.

170 Driving and Operating
when on dry pavement. SeeAntilock Brake System(ABS)0188.
.Allow greater following distanceand watch for slippery spots. Icypatches can occur on otherwiseclear roads in shaded areas.The surface of a curve or anoverpass can remain icy whenthe surrounding roads are clear.Avoid sudden steeringmaneuvers and braking whileon ice.
.Turn off cruise control.
Blizzard Conditions
Stop the vehicle in a safe place andsignal for help. Stay with the vehicleunless there is help nearby.If possible, use RoadsideAssistance. SeeRoadsideAssistance Program0316.Togethelp and keep everyone in thevehicle safe:
.Turn on the hazard warningflashers.
.Tie a red cloth to an outsidemirror.
{Warning
Snow can trap engine exhaust
under the vehicle. This may
cause exhaust gases to get
inside. Engine exhaust contains
carbon monoxide (CO), which
cannot be seen or smelled. It can
cause unconsciousness and even
death.
If the vehicle is stuck in snow:
.Clear snow from the base ofthe vehicle, especially anyblocking the exhaust pipe.
.Open a window about 5 cm(2 in) on the vehicle sidethat is away from the wind,to bring in fresh air.
.Fully open the air outlets onor under the instrumentpanel.
.Adjust the climate controlsystem to circulate the airinside the vehicle and set
(Continued)
Warning (Continued)
the fan speed to the highestsetting. See“ClimateControl Systems.”
For more information about CO,
seeEngine Exhaust0182.
To s a v e f u e l , r u n t h e e n g i n e f o rshort periods to warm the vehicleand then shut the engine off andpartially close the window. Movingabout to keep warm also helps.
If it takes time for help to arrive,when running the engine, push theaccelerator pedal slightly so theengine runs faster than the idlespeed. This keeps the batterycharged to restart the vehicle and tosignal for help with the headlamps.Do this as little as possible, tosave fuel.

If the Vehicle Is Stuck
Slowly and cautiously spin thewheels to free the vehicle whenstuck in sand, mud, ice, or snow.
If stuck too severely for the tractionsystem to free the vehicle, turn thetraction system off and use therocking method. SeeTr a c t i o nControl/Electronic StabilityControl0190.
{Warning
If the vehicle's tires spin at high
speed, they can explode, and you
or others could be injured. The
vehicle can overheat, causing an
engine compartment fire or other
damage. Spin the wheels as little
as possible and avoid going
above 56 km/h (35 mph).
Rocking the Vehicle to Get
it Out
Turn the steering wheel left andright to clear the area around thefront wheels. Turn off any tractionsystem. Shift back and forth
between R (Reverse) and a lowforward gear, spinning the wheelsas little as possible. To preventtransmission wear, wait until thewheels stop spinning before shiftinggears. Release the acceleratorpedal while shifting, and presslightly on the accelerator pedalwhen the transmission is in gear.Slowly spinning the wheels in theforward and reverse directionscauses a rocking motion that couldfree the vehicle. If that does not getthe vehicle out after a few tries, itmight need to be towed out. If thevehicle does need to be towed out,seeTo w i n g t h e V e h i c l e0286.
Vehicle Load Limits
It is very important to know how
much weight the vehicle can
carry. This weight is called the
vehicle capacity weight and
includes the weight of all
occupants, cargo, and all
nonfactory-installed options.
Two labels on the vehicle may
show how much weight it was
designed to carry, the Tire and
Loading Information label and
the Certification/Tire label.
{Warning
Do not load the vehicle any
heavier than the Gross
Vehicle Weight Rating
(GVWR), or either the
maximum front or rear Gross
Axle Weight Rating (GAWR).
This can cause systems to
break and change the way the
vehicle handles. This could
cause loss of control and a
crash. Overloading can also
reduce stopping distance,
damage the tires, and shorten
the life of the vehicle.
