If equipped with Keyless Access,the exterior lamps automatically turnon when a door is opened after theignition is changed to the OFFposition. The dome lamps alsocome on after the ignition ischanged to the OFF position. SeeIgnition Positions (Key Access)0182orIgnition Positions (KeylessAccess)0183.
The exterior lamps turn offimmediately by turning the exteriorlamps control off.
This feature can be changed. SeeVehicle Personalization0127.
Battery Load
Management
The vehicle has Electric PowerManagement (EPM) that estimatesthe battery's temperature and stateof charge. It then adjusts the voltagefor best performance and extendedlife 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 InformationCenter (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 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 to
generate 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.
Battery Power Protection
The battery saver feature isdesigned to protect the vehicle'sbattery.
If some interior lamps are left onand the ignition is turned off, thebattery rundown protection systemautomatically turns the lamp off aftersome time.
Exterior Lighting Battery
Saver
The exterior lamps turn off about10 minutes after the ignition isturned off, if the parking lamps orheadlamps have been manually lefton. This protects against draining

Engine Oil
To e n s u r e p r o p e r e n g i n eperformance and long life, carefulattention must be paid to engine oil.
Following these simple, butimportant steps will help protectyour investment:
.Use engine oil approved to theproper specification and of theproper viscosity grade. See“Selecting the Right Engine Oil”in this section.
.Check the engine oil levelregularly and maintain theproper oil level. See“CheckingEngine Oil”and“When to AddEngine Oil”in this section.
.Change the engine oil at theappropriate time. SeeEngine OilLife System0222.
.Always dispose of engine oilproperly. See“What to Do withUsed Oil”in this section.
If the engine oil pressure lightcomes on, check the engine oil levelright away. The oil pressure light ison the instrument cluster. SeeEngine Oil Pressure Light011 8.Check the engine oil level regularly;this is an added reminder.
Checking Engine Oil
Check the engine oil level regularly(every 650 km (400 mi), especiallyprior to a long trip. The engine oildipstick handle is a loop. SeeEngine Compartment Overview0217for the location.
{Warning
The engine oil dipstick handle
may be hot; it could burn you.
Use a towel or glove to touch the
dipstick handle.
If a low oil Driver Information Center(DIC) message displays, check theoil level.

{Warning
An electric engine cooling fan
under the hood can start up even
when the engine is not running
and can cause injury. Keep
hands, clothing, and tools away
from any underhood electric fan.
{Warning
Heater and radiator hoses, and
other engine parts, can be very
hot. Do not touch them. If you do,
you can be burned.
Do not run the engine if there is a
leak. If you run the engine, it
could lose all coolant. That could
cause an engine fire, and you
could be burned. Get any leak
fixed before you drive the vehicle.
Caution
Using coolant other than
DEX-COOL®can cause
premature engine, heater core,
or radiator corrosion. In addition,
the engine coolant could require
changing sooner. Any repairs
would not be covered by the
vehicle warranty. Always use
DEX-COOL (silicate-free) coolant
in the vehicle.

1. Remove the coolant surge tankpressure cap when the coolingsystem, including the coolantsurge tank pressure cap andupper radiator hose, is nolonger hot.
Turn the pressure cap slowlycounterclockwise aboutone-quarter of a turn. If youhear a hiss, wait for that tostop. This will allow anypressure still left to be ventedout the discharge hose.
2. Keep turning the pressure capslowly and remove it.
3. Fill the coolant surge tank withthe proper DEX-COOL coolantmixture to the indicatedlevel mark.
4. With the coolant surge tankpressure cap off, start theengine and let it run until youcan feel the upper radiatorhose getting hot. Watch out forthe engine cooling fan.

By this time, the coolant levelinside the coolant surge tankmay be lower. If the level islower, add more of the properDEX-COOL coolant mixture tothe coolant surge tank until thelevel reaches the indicatedlevel mark.
5. Replace the pressure captightly.
Check the level in the coolant surgetank when the cooling system hascooled down. If the coolant is not atthe proper level, repeat Steps 1–3andreinstallthepressurecap.If the coolant still is not at the properlevel when the system cools downagain, see your dealer.
Caution
If the pressure cap is not tightly
installed, coolant loss and
possible engine damage may
occur. Be sure the cap is properly
and tightly secured.
Engine Overheating
The vehicle has an indicator to warnof the engine overheating.
If the decision is made not to lift thehood when this warning appears,get service help right away. SeeRoadside AssistanceProgram0311.
If the decision is made to lift thehood, make sure the vehicle isparked on a level surface.
Then check to see if the enginecooling fan is running. If the engineis overheating, the fan should berunning. If it is not, do not continueto run the engine. Have the vehicleserviced.
Caution
Running the engine without
coolant may cause damage or a
fire. Vehicle damage would not be
covered by the vehicle warranty.
If Steam Is Coming from the
Engine Compartment
{Warning
Steam from an overheated engine
can burn you badly, even if you
just open the hood. Stay away
from the engine if you see or hear
steam coming from it. Just turn it
off and get everyone away from
the vehicle until it cools down.
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 be

too 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) for an automatictransmission or Neutral for amanual transmission, and letthe engine idle.
If the overheat warning no longerdisplays, the vehicle can be driven.Continue to drive the vehicle slowlyfor about 10 minutes. Keep a safevehicle distance from the vehicle infront. If the warning does not come
back on, continue to drive normallyand have the cooling systemchecked for 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.
