Battery Management System
The battery management system monitorsbattery conditions and takes actions toextend battery life. If excessive battery drainis detected, the system temporarily disablessome of the following features:
•Heated rear window.
•Heated seats.
•Climate control.
•Heated steering wheel.
•Audio unit.
•Navigation system.
A message may appear in the informationdisplay to alert you that battery protectionactions are active.
After battery replacement, or in some casesafter charging the battery with an externalcharger, the battery management systemrequires eight hours of vehicle sleep time torelearn the battery state of charge. Duringthis time your vehicle must remain fullylocked with the ignition off.
Note:If you add electrical accessories orcomponents to the vehicle, it may adverselyaffect battery performance and durability.This may also affect the performance ofother electrical systems in the vehicle.
Battery Disposal
Make sure that you dispose of oldbatteries in an environmentallyfriendly way. Seek advice fromyour local authority about recycling oldbatteries.
ADJUSTING THE HEADLAMPS
Vertical Aim Adjustment
The headlamps on your vehicle are properlyaimed at the assembly plant. If your vehiclehas been involved in a crash, have the aimof the headlamp beam checked by anauthorized dealer.
Headlamp Aiming Target
8 ft (2.4 m).A
Center height of lamp to ground.B
25 ft (7.6 m).C
Horizontal reference line.D
Vertical Aim Adjustment Procedure
1.Park the vehicle directly in front of a wallor screen on a level surface,approximately 25 ft (7.6 m) away.

2.Measure the height of the headlamp bulbcenter from the ground and mark an 8 ft(2.4 m) horizontal reference line on thevertical wall or screen at this height.
Note:To see a clearer light pattern foradjusting, you may want to block the lightfrom one headlamp while adjusting theother.
3.Turn on the low beam headlamps toilluminate the wall or screen and openthe hood.
4.On the wall or screen you will observe aflat zone of high intensity light at the topof the right hand portion of the beampattern. If the top edge of the highintensity light zone is not at the horizontalreference line, the headlamp needs tobe adjusted.

5.Locate the vertical adjuster on eachheadlamp. Using a Phillips #2screwdriver, turn the adjuster eitherclockwise or counterclockwise in order
to adjust the vertical aim of theheadlamp. The horizontal edge of thebrighter light should touch the horizontalreference line.
6.Close the hood and turn off the lamps.

PREPARING YOUR VEHICLE FOR
STORAGE
If you plan on storing your vehicle for 30days or more, the following maintenancerecommendations ensures your vehicle staysin good operating condition.
Under various conditions, long-term storagemay lead to degraded engine performanceor failure unless you use specific precautionsto preserve your vehicle.
General
•Store all vehicles in a dry, ventilatedplace.
•If vehicles are stored outside, theyrequire regular maintenance to protectagainst rust and weather damage.
•Make sure all linkages, cables, levers andpins under your vehicle are covered withgrease to prevent rust.
•Move vehicles at least 25 ft (7.5 m) every15 days to lubricate working parts andprevent corrosion.
•Fill the fuel tank with high-quality fueluntil the first automatic shutoff of the fuelpump nozzle.
Engine
•Change the engine oil and filter prior tostorage because used engine oil containscontaminants which may cause enginedamage.
•Start the engine every 15 days for aminimum of 15 minutes. Run at fast idlewith the climate controls set to defrostuntil the engine reaches normaloperating temperature.
•With your foot on the brake, shift throughall the gears while the engine is running.
Body
•Wash your vehicle thoroughly to removedirt, grease, oil, tar or mud from exteriorsurfaces, rear wheel housings and theunderside of front fenders.
•Periodically wash your vehicle if it isstored in exposed locations.
•Touch-up exposed or primed metal toprevent rust.
•Cover chrome and stainless steel partswith a thick coat of auto wax to preventdiscoloration. Rewax as necessary whenyou wash your vehicle.
•Lubricate all hood, door and luggagecompartment hinges and latches with alight grade oil.
•Cover interior trim to prevent fading.
•Keep all rubber parts free from oil andsolvents.

WHAT IS THE TIRE PRESSURE
MONITORING SYSTEM
The tire pressure monitoringsystem measures the vehicle's tirepressures. A warning lampilluminates if one or more tires aresignificantly underinflated or if there is asystem malfunction.
TIRE PRESSURE MONITORING
SYSTEM OVERVIEW
WARNING: Under-inflation is themost common cause of tire failures andmay result in severe tire cracking, treadseparation or blowout, with unexpectedloss of vehicle control and increased riskof injury. Under-inflation increases sidewallflexing and rolling resistance, resulting in
heat buildup and internal damage to thetire. It also may result in unnecessary tirestress, irregular wear, loss of vehiclecontrol and accidents. A tire can lose upto half of its air pressure and not appearto be flat!
WARNING: To determine therequired pressure(s) for your vehicle, seethe Safety Compliance Certification Label(on the door hinge pillar, door-latch postor the door edge that meets the door-latchpost, next to the driver seat) or the TireLabel on the B-Pillar or the edge of thedriver door.
Each tire, including the spare (if provided),should be checked monthly when cold andinflated to the inflation pressurerecommended by the vehicle manufactureron the vehicle placard or tire inflationpressure label. (If your vehicle has tires of adifferent size than the size indicated on thevehicle placard or tire inflation pressure label,you should determine the proper tire inflationpressure for those tires).
As an added safety feature, your vehicle hasbeen equipped with a Tire PressureMonitoring System (TPMS) that illuminates alow tire pressure telltale when one or moreof your tires is significantly under-inflated.Accordingly, when the low tire pressuretelltale illuminates, you should stop andcheck your tires as soon as possible, andinflate them to the proper pressure. Drivingon a significantly under-inflated tire causesthe tire to overheat and can lead to tirefailure. Under-inflation also reduces fuelefficiency and tire tread life, and may affectthe vehicle’s handling and stopping ability.
Please note that the TPMS is not a substitutefor proper tire maintenance, and it is thedriver’s responsibility to maintain correct tirepressure, even if under-inflation has notreached the level to trigger illumination ofthe TPMS low tire pressure telltale.
