If you replace the battery make sure itmatches the electrical requirements ofyour vehicle.
If you disconnect or replace the batteryand your vehicle has an automatictransmission, it must relearn its adaptivestrategy. Because of this, the transmissionmay shift firmly when first driven. This isnormal operation while the transmissionfully updates its operation to optimumshift feel.
Battery Sensor Reset
When you install a new battery, reset thebattery sensor by doing the following:
1.Switch the ignition on, and leave theengine off.
Note:Complete Steps 2 and 3 within 10seconds.
2.Flash the high beam headlamps fivetimes, ending with the high beams off.
3.Press and release the brake pedal threetimes.
The battery warning lamp flashes threetimes to confirm that the reset issuccessful.
Battery Management System (If
Equipped)
The system monitors battery conditionsand takes actions to extend battery life. Ifexcessive battery drain is detected, thesystem temporarily disables someelectrical systems to protect the battery.
Systems included are:
•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. This message is only fornotification that an action is taking place,and not intended to indicate an electricalproblem or that the battery requiresreplacement.
After battery replacement, or in somecases after charging the battery with anexternal charger, the battery managementsystem requires eight hours of vehicle sleeptime to relearn the battery state of charge.During this time, your vehicle must remainfully locked with the ignition switched off.
Note:Prior to relearning the battery stateof charge, the battery management systemmay temporarily disable some electricalsystems.
Electrical Accessory Installation
To make sure the battery managementsystem works correctly, do not connect anelectrical device ground connectiondirectly to the battery negative post. Thiscan cause inaccurate measurements ofthe battery condition and potentialincorrect system operation.
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.
Remove and Reinstall the Battery
Install a battery approved for use by ourspecifications. See Capacities andSpecifications (page 463).
To disconnect or remove the battery, dothe following:
1.Apply the parking brake and switch theignition off.
2.Switch all electrical equipment off, forexample lights and radio.

To avoid potential Four-WheelDrive (4WD) malfunction or(4WD) system damage, it isrecommended to replace all fourtires rather than mixingsignificantly worn tires with newtires.
The tire pressure sensors mountedin the wheels (originally installedon your vehicle) are not designedto be used in aftermarket wheels.
The use of wheels or tires notrecommended may affect theoperation of your tire pressuremonitoring system.
If the tire pressure monitoringsystem indicator is flashing, yoursystem is malfunctioning. Yourreplacement tire might beincompatible with your tirepressure monitoring system, orsome component of the systemmay be damaged.
USING SNOW CHAINS
WARNING: Do not exceed 30 mph(50 km/h). Failure to follow thisinstruction could result in the loss ofcontrol of your vehicle, personal injury ordeath.
WARNING: Do not use snow chainson snow-free roads.
WARNING: Only fit snow chains tospecified tires.
WARNING: If your vehicle is fittedwith wheel trims, remove them beforefitting snow chains.
WARNING: If you choose to installsnow tires on your vehicle, they must bethe same size, construction, and loadrange as the original tires listed on thetire placard, and they must be installedon all four wheels. Mixing tires ofdifferent size or construction on yourvehicle can adversely affect yourvehicle's handling and braking, and maylead to loss of vehicle control.
WARNING: Wheels and tires mustbe the same size, load index and speedrating as those originally fitted on thevehicle. Use of any other tire or wheelcan affect the safety and performanceof your vehicle. Additionally, the use ofnon-recommended tires and wheels cancause steering, suspension, axle, transfercase or power transfer unit failure.Follow the recommended tire inflationpressures found on the SafetyCompliance Certification label, or theTire Label on the B-Pillar or the edge ofthe driver door. Failure to follow thisinstruction could result in loss of vehiclecontrol, vehicle rollover, or personal injuryor death.
Only use snow chains on rear wheels.Install snow chains in pairs. Do not useself-tensioning snow chains.
Only use snow chains on the followingspecified tire sizes. Only install chains thatare 15mm or less (SAE Class S chains).
