FUEL GAUGE LIMITATIONS
The fuel gauge may not provide anaccurate reading when your vehicle is onan incline.
LOCATING THE FUEL FILLERDOOR
The arrow adjacent to the fuel pumpsymbol indicates on which side of yourvehicle the fuel filler door is located.
WHAT IS THE LOW FUELREMINDER
A low fuel level reminder displays andsounds when the distance to emptyreaches 50 mi (80 km),25 mi (40 km),12 mi (20 km) and 0 mi (0 km).
Note:The low fuel reminder can appear atdifferent fuel gauge positions depending onfuel economy conditions. This variation isnormal.
WHAT IS DISTANCE TO EMPTY
Indicates the approximate distance yourvehicle can travel on the fuel remaining inthe tank. Changes in driving pattern cancause the value to not only decrease butalso increase or stay constant for periodsof time.
Note:When you have a trailer connected,your distance to empty accounts for thetrailer.

Indicates the engine oil pressure.
Note:This is a configurable gauge.
ENGINE OIL TEMPERATURE
GAUGE
Indicates the engine oil temperature.
Note:This is a configurable gauge.

INSTRUMENT CLUSTER
WARNING LAMPS
Depending on your vehicle options, somewarning lamps can appear different or notat all.
Anti-Lock Brake System
If it illuminates when you aredriving, this indicates amalfunction. Your vehiclecontinues to have normal braking withoutthe anti-lock brake system function. Haveyour vehicle checked as soon as possible.
Battery
It illuminates when you switchthe ignition on.
If it illuminates when the engineis running, this indicates your vehiclerequires service. Have your vehiclechecked as soon as possible.
Brake System
It illuminates when you apply theparking brake and the ignition ison. If it illuminates when yourvehicle is moving, make sure theparking brake is released. If theparking brake is released, thisindicates low brake fluid level or the brakesystem requires service. Have your vehiclechecked as soon as possible.
Note:Indicators may vary depending onregion.
Diesel Exhaust Fluid
Illuminates when the dieselexhaust fluid is low,contaminated or the systemrequires service. See Selective CatalyticReduction System (page 226).
Door Ajar
It illuminates when you switchthe ignition on and remains on ifany door is open.
Electric Parking Brake
It illuminates or flashes when theelectric parking brake requiresservice.
Note:Indicators may vary depending onregion.
Engine Coolant Temperature
If it illuminates, safely stop yourvehicle and switch the vehicleoff.

Your vehicle has limited engine powerwhen in the fail-safe mode, drive yourvehicle with caution. Your vehicle does notmaintain high-speed operation and theengine may operate 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 recommendthat you contact your roadsideassistance service 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,you can re-start the engine. Have yourvehicle checked as soon as possible tominimize engine 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 anda message may appear in theinstrument cluster display.

COOLANT
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 capwith a thick cloth to prevent thepossibility of scalding and slowly removethe cap. Failure to follow this instructioncould result in personal injury.
WARNING: To reduce the risk ofpersonal injury, make sure the engine iscool before unscrewing the coolantpressure relief cap. The cooling systemis under pressure. Steam and hot liquidcan come out forcefully when you loosenthe cap slightly.
When the engine is cold, check theconcentration and level of the coolant atthe intervals listed in the scheduledmaintenance information. See ScheduledMaintenance (page 591).
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.
Maintain coolant concentration within48% to 50%, which equates to a freezepoint between -29°F (-34°C) and -35°F(-37°C). Coolant concentration should bechecked using a refractometer. We do notrecommend the use of hydrometers orcoolant test strips for measuring coolantconcentration.
ADDING COOLANT
WARNING: Do not add coolantwhen the vehicle is on or the coolingsystem is hot. Failure to follow thisinstruction could result in personal 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 capwith a thick cloth to prevent thepossibility of scalding and slowly removethe cap. Failure to follow this instructioncould result in personal injury.
WARNING: Do not allow the fluidto touch your skin or eyes. If thishappens, rinse the affected areasimmediately with plenty of water andcontact your physician.
WARNING: Do not put coolant inthe windshield washer reservoir. Ifsprayed on the windshield, coolant couldmake it difficult to see through thewindshield.
WARNING: Do not add coolantfurther than the MAX mark.
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.
Note:Automotive fluids are notinterchangeable.
