Leaving the Vehicle With the Engine
Running
{WARNING:
It can be dangerous to leave the vehicle with the
engine running. The vehicle could move suddenly if
the shift lever is not fully in P (Park) with the parking
brake firmly set. And, if you leave the vehicle with
the engine running, it could overheat and even
catch fire. You or others could be injured. Do not
leave the vehicle with the engine running.
If you have to leave the vehicle with the engine running,be sure your vehicle is in P (Park) and the parkingbrake is firmly set before you leave it. SeeParking Brakeon page 3-30for more information.
Torque Lock
Torque lock is when the weight of the vehicle puts toomuch force on the parking pawl in the transmission.This happens when parking on a hill and shiftingthe transmission into P (Park) is not done properly andthen it is difficult to shift out of P (Park).
To prevent torque lock, set the parking brake and thenshift into P (Park). To find out how, see “ShiftingInto Park” in this section.
If torque lock does occur, your vehicle may need to bepushed uphill by another vehicle to relieve the parkingpawl pressure, so you can shift out of P (Park).
Shifting Out of Park
Automatic Transmission Shift Lock
This vehicle has an electronic shift lock release system.The shift lock release is designed to:
•Prevent ignition key removal unless the shift lever is
in P (Park)
•Prevent movement of the shift lever out of P (Park),
unless the ignition is in ON/RUN orACC/ACCESSORY and the regular brake pedal isapplied.
The shift lock is always functional except in the case of aan uncharged or low voltage (less than 9 volt) battery.
If the vehicle has an uncharged battery or a battery withlow voltage, try charging or jump starting the battery.SeeJump Starting on page 6-36.

Electric Power Management
The vehicle has Electric Power Management (EPM) thatestimates the battery’s temperature and state ofcharge. It then adjusts the voltage for best performanceand extended life of the battery.
When the battery’s state of charge is low, the voltage israised slightly to quickly bring the charge back up.When the state of charge is high, the voltage is loweredslightly to prevent overcharging. If the vehicle has avoltmeter gage or a voltage display on the DriverInformation Center (DIC), you may see the voltage moveup or down. This is normal. If there is a problem, analert will be displayed.
The battery can be discharged at idle if the electricalloads are very high. This is true for all vehicles. This isbecause the generator (alternator) may not bespinning fast enough at idle to produce all the powerthat is needed for very high electrical loads.
A high electrical load occurs when several of thefollowing are on, such as: headlamps, high beams, foglamps, rear window defogger, climate control fan athigh speed, heated seats, engine cooling fans, trailerloads, and loads plugged into accessory power outlets.
EPM works to prevent excessive discharge of thebattery. It does this by balancing the generator’s outputand the vehicle’s electrical needs. It can increase
engine idle speed to generate more power, wheneverneeded. It can temporarily reduce the power demands ofsome accessories.
Normally, these actions occur in steps or levels, withoutbeing noticeable. In rare cases at the highest levelsof corrective action, this action may be noticeable to thedriver. If so, a Driver Information Center (DIC)message might be displayed, such as BATTERYSAVER ACTIVE, BATTERY VOLTAGE LOW, orLOW BATTERY. If this message is displayed, it isrecommended that the driver reduce the electrical loadsas much as possible. SeeDIC Warnings and Messageson page 4-67.
Inadvertent Power Battery Saver
This feature is designed to protect your vehicle’s batteryagainst drainage from the interior lamps, trunk lamp,glove box lamp, or the garage door opener. When theignition is turned off, the power to these features willautomatically turn off after 10 minutes. Power willbe restored for an additional 10 minutes if any door ortrunk is opened, or the courtesy lamp switch isturned on.

Charging System Light
This light comes on brieflywhen the ignition key isturned to START, butthe engine is not running,as a check to show itis working.
If it does not, have the vehicle serviced by yourdealer/retailer.
The light should go out once the engine starts. If it stayson, or comes on while driving, there could be aproblem with the charging system. A charging systemmessage in the Driver Information Center (DIC) can alsoappear. SeeDIC Warnings and Messages on page 4-67for more information. This light could indicate thatthere are problems with a generator drive belt, or thatthere is an electrical problem. Have it checked rightaway. If the vehicle must be driven a short distance withthe light on, turn off accessories, such as the radioand air conditioner.
Brake System Warning Light
The vehicle’s hydraulic brake system is divided intotwo parts. If one part is not working, the other part canstill work and stop the vehicle. For good brakingboth parts need to be working.
If the warning light comes on, there is a brake problem.Have the brake system inspected right away.
This light comes on briefly when the engine is turnedon. If it does not come on then, have it fixed so it will beready to warn if there is a problem.
When the ignition is on, the brake system warning lightalso comes on when the parking brake is set. Thelight will stay on if the parking brake does not releasefully. If it stays on after the parking brake is fullyreleased, it means there is a brake problem.

To turn on the timer, press the set/reset button untilTIMER ON displays. The timer will then start.
To turn off the timer, press the set/reset button againuntil TIMER OFF displays. The timer will stop anddisplay the end timing value.
To reset the timer, press and hold the set/reset buttonafter the timer has been stopped. The display will returnto zero.
AVERAGE SPEED
This display shows the average speed of the vehicle ineither kilometers per hour (km/h) or miles perhour (mph). This average is calculated based on thevarious vehicle speeds recorded since the last reset ofthis display. To reset this display, press the set/resetbutton. The display will return to zero.
BATTERY VOLTAGE
This display shows the current battery voltage. If thevoltage is in the normal range, the value will display. Forexample, the display may read BATTERY VOLTAGE13.2 VOLTS. If the voltage is low, the display will showLOW. If the voltage is high, the display will showHIGH. Your vehicle’s charging system regulates voltagebased on the state of the battery. The battery voltagemay fluctuate when viewing this information on the DIC.This is normal. SeeCharging System Light onpage 4-52for more information.
If there is a problem with the battery charging system,the DIC will display a message. SeeDIC Warningsand Messages on page 4-67andElectric PowerManagement on page 4-33for more information.

Radio Reception
Frequency interference and static can occur duringnormal radio reception if items such as cell phonechargers, vehicle convenience accessories, and externalelectronic devices are plugged into the accessorypower outlet. If there is interference or static, unplug theitem from the accessory power outlet.
AM
The range for most AM stations is greater than for FM,especially at night. The longer range can cause stationfrequencies to interfere with each other. For better radioreception, most AM radio stations boost the power levelsduring the day, and then reduce these levels during thenight. Static can also occur when things like storms andpower lines interfere with radio reception. When thishappens, try reducing the treble on the radio.
FM Stereo
FM signals only reach about 10 to 40 miles(16 to 65 km). Although the radio has a built-in electroniccircuit that automatically works to reduce interference,some static can occur, especially around tall buildings orhills, causing the sound to fade in and out.
XM™ Satellite Radio Service
XM Satellite Radio Service gives digital radio receptionfrom coast-to-coast in the 48 contiguous United States,and in Canada. Just as with FM, tall buildings or hills caninterfere with satellite radio signals, causing the sound tofade in and out. In addition, traveling or standing underheavy foliage, bridges, garages, or tunnels may causeloss of the XM signal for a period of time.
Cellular Phone Usage
Cellular phone usage may cause interference with thevehicle’s radio. This interference may occur whenmaking or receiving phone calls, charging the phone’sbattery, or simply having the phone on. This interferencecauses an increased level of static while listening tothe radio. If static is received while listening to the radio,unplug the cellular phone and turn it off.
