Water alone, without engine coolant, cancause engine damage from corrosion,overheating or freezing.
Do not use the following as a coolantsubstitute, as they can cause enginedamage from overheating or freezing:
•Alcohol.
•Methanol.
•Brine.
•Any coolant mixed with alcohol ormethanol antifreeze.
Do not add extra inhibitors or additives tothe coolant. These can be harmful andcompromise the corrosion protection ofthe coolant.
Severe Climates
If you drive in extremely cold climates, youmay need to increase the coolantconcentration above 50%.
Note:A coolant concentration of 60%provides improved freeze point protection.Coolant concentrations above 60%decrease the overheat protectioncharacteristics of the coolant and couldcause engine damage.
If you drive in extremely hot climates, youmay need to decrease the coolantconcentration to 40%.
Note:A coolant concentration of 40%provides improved overheat protection.Coolant concentrations below 40%decrease the overheat and corrosionprotection characteristics of the coolant andcould cause engine damage.
Coolant Change
WARNING: Do not dispose ofcoolant in the household refuse or thepublic sewage system. Use an authorizedwaste disposal facility.
Change the coolant at specific mileageintervals. Refer to the scheduledmaintenance information. See NormalScheduled Maintenance (page 462).
Note:Dispose of used coolant in theappropriate manner.
Follow your community's regulations andstandards for recycling and disposing ofautomotive fluids.
Fail-Safe Cooling
Fail-safe cooling allows you to temporarilydrive your vehicle before any incrementalcomponent damage occurs. The fail-safedistance depends on ambienttemperature, vehicle load and terrain.
How Fail-Safe Cooling Works
WARNING: If you continue to driveyour vehicle when the engine isoverheating, the engine could stopwithout warning. Failure to follow thisinstruction could result in the loss ofcontrol of your vehicle.
If the engine begins to overheat,the coolant temperature gaugemoves toward the red zone:
A warning lamp illuminates anda message may appear in theinformation display.
If the engine reaches a presetover-temperature condition, the engineautomatically switches to alternatingcylinder operation. Each disabled cylinderacts as an air pump and cools the engine.
When this occurs, your vehicle stilloperates, however:
•Engine power is limited.
•The air conditioning system turns off.

WHAT ARE THE AUXILIARY
SWITCHES
The auxiliary switchboard on the overheadconsole makes aftermarket customizationeasier with six prewired switchesconnected to the power distribution box.Each circuit is individually fused forconnection of electrical accessories.
For maximum vehicle performance, keepthe following information in mind whenadding accessories or equipment to yourvehicle:
•When adding accessories, equipment,passengers and luggage to yourvehicle, do not exceed the total weightcapacity of the vehicle or of the frontor rear axle (GVWR or GAWR asindicated on the safety compliancecertification label). Ask an authorizeddealer for specific weight information.
•It is your responsibility to ensure thatany equipment you have fittedcomplies with applicable locallegislation.
•An authorized dealer needs to installmobile communication systems.Improper installation may harm theoperation of your vehicle, particularlyif the manufacturer did not design themobile communication systemspecifically for automotive use.
•If you or an authorized dealer add anyelectrical or electronic accessories orcomponents not produced by us toyour vehicle, you may adversely affectbattery performance and durability. Inaddition, you may also adversely affectthe performance of the other electricalsystems in the vehicle.
LOCATING THE AUXILIARY
SWITCHES
The switches are labeled AUX 1 throughAUX 6. They only operate when the ignitionis in the on position or in the off positionwhen Delay Accessory is active, whetherthe engine is running or not. Werecommend that you leave the enginerunning to maintain battery charge whenusing the switches for an extended time orwhen using higher current drawaccessories. When a switch is turned on,the indicator light on the switch illuminatesand the circuit provides power to thedevice wired to that switch.

SWITCH WIRING
There are six powered circuits and fivenon-powered circuits.
