Fuel Gauge
The fuel gauge indicates about how muchfuel is in the fuel tank.
The arrow adjacent to the fuel pump symbolindicates on which side of your vehicle thefuel filler door is located.
Note:The fuel gauge may vary slightly whenyour vehicle is moving or on a slope.
Low Fuel Reminder
A low fuel level reminder displays andsounds when the distance to empty reaches75 mi (120 km) to empty for MyKey, and at50 mi (80 km), 25 mi (40 km), 10 mi (20 km)and 0 mi (0 km) for all vehicle keys.
Note:The low fuel reminder can appear atdifferent fuel gauge positions depending onfuel economy conditions. This variation isnormal.
Engine Coolant Temperature Gauge
WARNING: Do not remove the coolantreservoir cap when the cooling system is hot.Wait 10 minutes for the cooling system tocool down. Cover the coolant reservoir capwith a thick cloth to prevent the possibilityof scalding and slowly remove the cap.Failure to follow this instruction could resultin personal injury.
Indicates engine coolant temperature. Atnormal operating temperature, the levelindicator will be in the normal range. If theengine coolant temperature exceeds thenormal range, stop the vehicle as soon assafely possible, switch off the engine and letthe engine cool.

ENGINE COOLANT CHECK
WARNING: Do not remove the coolantreservoir cap when the cooling system is hot.Wait 10 minutes for the cooling system tocool down. Cover the coolant reservoir capwith a thick cloth to prevent the possibilityof scalding and slowly remove the cap.Failure to follow this instruction could resultin personal injury.
WARNING: Do not put coolant in thewindshield washer reservoir. If sprayed onthe windshield, coolant could make it difficultto see through the windshield.
WARNING: To reduce the risk ofpersonal injury, make sure the engine is coolbefore unscrewing the coolant pressure reliefcap. The cooling system is under pressure.Steam and hot liquid can come out forcefullywhen you loosen the cap slightly.
WARNING: Do not add coolant furtherthan the MAX mark.
When the engine is cold, check theconcentration and level of the coolant at theintervals listed in the scheduled maintenanceinformation. See Scheduled Maintenance(page 504).
Note:Make sure that the coolant level isbetween the MIN and the MAX marks onthe coolant reservoir.
Note: Coolant expands when it is hot. Thelevel may extend beyond the MAX mark.

Maintenance

Maintain coolant concentration within 48%to 50%, which equates to a freeze pointbetween -30°F (-34°C) and -34°F (-37°C).Coolant concentration should be checkedusing a refractometer. We recommend,Robinair® Coolant and Battery Refractometer75240 (Rotunda tool part number:ROB75240). We do not recommend the useof hydrometers or coolant test strips formeasuring coolant concentration.
Note: Automotive fluids are notinterchangeable. Do not use coolant orwindshield washer fluid outside of itsspecified function and vehicle location.
Note: Do not use stop leak pellets, coolingsystem sealants, or non-specified additivesas they can cause damage to the enginecooling or heating systems. Resultingcomponent damage may not be covered bythe vehicle Warranty.
Adding Coolant
WARNING: Do not add engine coolantwhen the engine is hot. Failure to follow thisinstruction could result in personal injury.
WARNING: Do not remove the coolantreservoir cap when the cooling system is hot.Wait 10 minutes for the cooling system tocool down. Cover the coolant reservoir capwith a thick cloth to prevent the possibilityof scalding and slowly remove the cap.Failure to follow this instruction could resultin personal injury.
It is very important to use prediluted coolantmeeting the correct specification in order toavoid plugging the small passageways in theengine cooling system. See Capacities andSpecifications (page 373). Incorrectprediluted coolant use can cause damagenot covered by the vehicle Warranty.
If the coolant level is at or below theminimum mark, add prediluted coolantimmediately.
To top up the coolant level do the following:
1. Unscrew the cap slowly. Any pressureescapes as you unscrew the cap.
2. Add prediluted coolant meeting thecorrect specification. See Capacities andSpecifications (page 366).
3.Add enough prediluted coolant to reachthe correct level.
4. Replace the coolant reservoir cap, turnit clockwise until you feel a strongresistance.
5. Check the coolant level in the coolantreservoir the next few times you driveyour vehicle.
Note:During normal vehicle operation, thecoolant may change color from orange topink or light red. As long as the coolant isclear and uncontaminated, this color changedoes not indicate the coolant has degradednor does it require the coolant to be drained,the system to be flushed, or the coolant tobe replaced.
Do not mix different colors or types ofprediluted coolant in your vehicle. Mixing ofprediluted coolant or using an incorrectprediluted coolant may harm the engine orcooling system components and may not becovered by the vehicle Warranty.
In case of emergency, you can add a largeamount of water without engine coolant inorder to reach a vehicle service location. Inthis instance, qualified personnel:

Maintenance

A warning lamp illuminates and amessage may appear in theinformation display.
If the engine reaches a presetover-temperature condition, the engineautomatically switches to alternating cylinderoperation. Each disabled cylinder acts as anair pump and cools the engine.
When this occurs, your vehicle still operates,however:
•Engine power is limited.
•The air conditioning system turns off.
Continued operation increases the enginetemperature, causing the engine tocompletely shut down. Your steering andbraking effort increases in this situation.
When the engine temperature cools, you canre-start the engine. Have your vehiclechecked as soon as possible to minimizeengine damage.
When Fail-Safe Mode Is Activated
WARNING: Fail-safe mode is for useduring emergencies only. Operate yourvehicle in fail-safe mode only as long asnecessary to bring your vehicle to rest in asafe location and seek immediate repairs.When in fail-safe mode, your vehicle will havelimited power, will not be able to maintainhigh-speed operation, and may completelyshut down without warning, potentially losingengine power, power steering assist, andpower brake assist, which may increase thepossibility of a crash resulting in seriousinjury.
WARNING: Do not remove the coolantreservoir cap when the cooling system is hot.Wait 10 minutes for the cooling system tocool down. Cover the coolant reservoir capwith a thick cloth to prevent the possibilityof scalding and slowly remove the cap.Failure to follow this instruction could resultin personal injury.
Your vehicle has limited engine power whenin the fail-safe mode, drive your vehicle withcaution. Your vehicle does not maintainhigh-speed operation and the engine mayoperate poorly.
Remember that the engine is capable ofautomatically shutting down to preventengine damage. In this situation:
1. Pull off the road as soon as safelypossible and switch the engine off.
2. If you are a member of a roadsideassistance program, we recommend thatyou contact your roadside assistanceservice provider.
3.If this is not possible, wait a short periodfor the engine to cool.
4. Check the coolant level. If the coolantlevel is at or below the minimum mark,add prediluted coolant immediately.
5.When the engine temperature cools, youcan re-start the engine. Have your vehiclechecked as soon as possible to minimizeengine damage.

Intelligent Oil-Life Monitor™
Your vehicle is equipped with an IntelligentOil-Life Monitor that determines when youshould change the engine oil based on howyour vehicle is used. By using severalimportant factors in its calculations, themonitor helps reduce the cost of owning yourvehicle and reduces environmental waste atthe same time.
This means you do not have to remember tochange the oil on a mileage-based schedule.Your vehicle lets you know when an oilchange is due by displaying a message inthe information display.
The following table provides examples ofvehicle use and its impact on oil changeintervals. It is a guideline only. Actual oilchange intervals depend on several factorsand generally decrease with severity of use.
