WHAT IS THE LOW FUEL REMINDER
A low fuel level reminder displays andsounds when the distance to empty reaches50 mi (80 km), 25 mi (40 km), 12 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.
VEHICLE RANGE DISPLAY
Displays the approximate range your vehiclecan travel with the energy currently onboard.Estimates vary based on the energy usedwhen driving.
Changes in driving pattern can cause thevalues to not only decrease but also increaseor stay constant for periods of time.
The amount of energy being used whendriving is affected by:
•Mild or aggressive acceleration orbraking.
•Your vehicle's speed.
•Use of accessories, such as climatecontrol.
•Ambient temperature and weatherconditions.
•Driving in a city or on a highway.
•Driving on hilly road conditions.
•Towing.
Note:It is normal for vehicle range estimatesto vary due to changes in average energyusage. This could cause different rangeestimates each time you fully charge yourbattery or fill your tank.
Note:Electric range is lower in coldtemperatures due to reduced energycapacity in the high voltage battery. Set adeparture time and cabin temperature tomaintain battery temperature for best rangeand performance. See What is a HybridElectric Vehicle (page 213). See Setting theCharging Schedule and Preferences (page250).
Gasoline Distance to Empty
Indicates the approximate distance yourvehicle can travel on the fuel remaining inthe tank.
Electric Range

maintain high-speed operation, and maycompletely shut down without warning,potentially losing engine power, powersteering assist, and power brake assist,which may increase the possibility of acrash resulting in serious injury.
WARNING: Do not remove thecoolant reservoir cap when the engine ison or the cooling system is hot. Wait 10minutes for the cooling system to cooldown. Cover the coolant reservoir cap witha thick cloth to prevent the possibility ofscalding and slowly remove the cap.Failure to follow this instruction could resultin personal injury.
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.
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 for a shortperiod of time for 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.
Note:Driving your vehicle without repairincreases the chance of engine damage.
FAIL-SAFE COOLING INDICATORS
If the engine begins to overheat,the coolant temperature gaugemoves toward the red zone.
A warning lamp illuminates and amessage may appear in theinstrument cluster display.

6.Wipe any dirt or debris from the air filterhousing assembly to make sure no dirtgets in the engine and to make sure youhave a good seal.
7.Install a new air filter element. Be carefulnot to crimp the filter element edgesbetween the air filter housing and cover. This could cause filter damage and allowunfiltered air to enter the engine if it isnot properly seated.
8.Install the air filter housing cover.
9.Engage the clips to secure the air filterhousing cover to the air filter housing.
10.Reconnect the boot to the air filterhousing cover and tighten securely.

CHECKING THE COOLANT LEVEL
WARNING: Do not remove thecoolant reservoir cap when the engine ison or the cooling system is hot. Wait 10minutes for the cooling system to cooldown. Cover the coolant reservoir cap witha thick cloth to prevent the possibility ofscalding and slowly remove the cap.Failure to follow this instruction could resultin personal injury.
WARNING: To reduce the risk ofpersonal injury, make sure the engine iscool before unscrewing the coolantpressure relief cap. The cooling system isunder pressure. Steam and hot liquid cancome out forcefully when you loosen thecap slightly.
When the engine is cold, check theconcentration and level of the coolant at theintervals listed in the scheduled maintenanceinformation. See Scheduled Maintenance(page 563).
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. This is normal.

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 approved to thecorrect specification. See Capacities andSpecifications (page 495).
3.Add enough prediluted coolant to reachthe correct level.
4.Replace the coolant reservoir cap. Turnthe cap clockwise until it contacts thehard stop.
5.Check the coolant level in the coolantreservoir the next few times you driveyour vehicle. If necessary, add enoughprediluted engine coolant to bring thecoolant level to the correct level.
If you have to add more than 1.1 qt (1 L) ofengine coolant per month, have your vehiclechecked as soon as possible. Operating anengine with a low level of coolant can resultin engine overheating and possible enginedamage.
In case of emergency, you can add a largeamount of water without engine coolant inorder to reach a vehicle service location.
Water alone, without engine coolant, cancause engine damage from corrosion,overheating or freezing.
Do not use the following as a coolantsubstitute:
•Alcohol.
•Methanol.
•Brine.
•Any coolant mixed with alcohol ormethanol antifreeze.
Alcohol and other liquids can cause enginedamage from overheating or freezing.
Do not add extra inhibitors or additives tothe coolant. These can be harmful andcompromise the corrosion protection of thecoolant.
CHANGING THE COOLANT
For coolant change, see your authorizeddealer.
Changing the coolant is necessary at specificmileage intervals listed in the scheduledmaintenance information.
MANAGING THE COOLANTTEMPERATURE
If you tow a trailer with your vehicle, theengine may temporarily reach a highertemperature during severe operatingconditions, for example ascending a long orsteep grade in high ambient temperatures.
At this time, you may notice the coolanttemperature gauge moves toward the redzone and a message may appear in theinformation display.
WARNING: To reduce the risk ofcrash and injury, be prepared that thevehicle speed may reduce and the vehiclemay not be able to accelerate with fullpower until the coolant temperaturereduces.
439
2023 Corsair (CTF) Canada/United States of America, enUSA, Edition date: 202208, DOMMaintenance

WARNING: If you continue to driveyour vehicle when the engine isoverheating, the engine could stop withoutwarning. Failure to follow this instructioncould result in the loss of control of yourvehicle.
You may notice a reduction in vehicle speedcaused by reduced engine power in orderto manage the engine coolant temperature. Your vehicle may enter this mode if certainhigh-temperature and high-load conditionstake place. The amount of speed reductiondepends on vehicle loading, grade andoutside temperature. If this occurs, there isno need to stop your vehicle. You cancontinue to drive. See Fail-Safe Cooling(page 407).
The air conditioning may automatically turnon and off during severe operatingconditions to protect the engine fromoverheating. When the coolant temperaturedecreases to the normal operatingtemperature, the air conditioning turns on.
If the coolant temperature gauge moves fullyinto the red zone, or if the coolanttemperature warning or service engine soonmessages appear in your information display,do the following:
1.Stop your vehicle as soon as it is safe todo so. Fully apply the parking brake, shiftinto park (P) or neutral (N).
2.Leave the engine running until thecoolant temperature gauge needlereturns to the normal position. If thetemperature does not drop after severalminutes, follow the remaining steps.
3.Switch the engine off and wait for it tocool. Check the coolant level.
4.If the coolant level is at or below theminimum mark, add prediluted coolantimmediately.
5.If the coolant level is normal, restart theengine and continue.
