Engine Oil Pressure Gauge
Indicates engine oil pressure. At normaloperating temperature, the level indicatoris in the normal range. If the pressure gaugefalls below the normal range, stop yourvehicle, switch off the engine and checkthe engine oil level. Add oil if needed. If theoil level is correct, have your vehiclechecked by an authorized dealer.
Speedometer
Indicates vehicle speed. Vehicle speed islimited to either 65 mph (105 km/h) or75 mph (120 km/h).
Transmission Fluid TemperatureGauge
Normal area
The transmission fluid is within the normaloperating temperature (between H andC).
Yellow area
The transmission fluid is higher thannormal operating temperature. This canbe caused by special operation conditions(snowplowing, towing or off-road use).
To lower the transmission temperatureinto the normal range, alter the severity ofyour driving conditions. Operating thetransmission for extended periods with thegauge in the higher than normal area maycause internal transmission damage. If thegauge continues to show hightemperatures, see an authorized dealer.
Red area
The transmission fluid is overheating. Stopthe vehicle to allow the temperature toreturn to normal range.
If the gauge is operating in the yellow orred area, stop the vehicle and verify theairflow is not restricted such as snow ordebris blocking airflow through the grille.If the gauge continues to show hightemperatures, see your authorized dealer.
Engine Coolant TemperatureGauge
WARNING: Do not remove thecoolant reservoir cap when the coolingsystem is hot. Wait 10 minutes for thecooling system to cool down. Cover thecoolant reservoir cap with a thick clothto prevent the possibility of scalding andslowly remove the cap. Failure to followthis instruction could result in personalinjury.
Indicates engine coolant temperature. Atnormal operating temperature, the levelindicator is in the normal range. If theengine coolant temperature exceeds thenormal range, stop your vehicle as soon aspossible, switch off the engine and let theengine cool.

Motorhome (TY3) Canada/United States of America, enUSA, Edition date: 201803, Third-Printing-Instrument Cluster E144522 E146190

If the light remains on while the engine isrunning, this indicates inadequate hydraulicbooster pressure or reserve pump systemfailure. Stop the vehicle as soon aspossible and seek service immediately byyour authorized dealer.
Cruise Control Indicator

Service Engine Soon
If it illuminates when the engineis running this indicates amalfunction. The On BoardDiagnostics system has detected amalfunction of the vehicle emission controlsystem.
If it flashes, engine misfire may beoccurring. Increased exhaust gastemperatures could damage the catalyticconverter or other vehicle components.Drive in a moderate fashion (avoid heavyacceleration and deceleration) and haveyour vehicle immediately serviced.
It illuminates when you switch the ignitionon prior to engine start to check the bulband to indicate whether your vehicle isready for Inspection and Maintenance(I/M) testing.

AUDIBLE WARNINGS AND
INDICATORS
Fail-Safe Cooling Warning Chime
Sounds when the coolant gauge pointerhas moved to hot. There are three stagesof chimes:

Some fuel stations, particularly those inhigh altitude areas, offer fuels posted asregular unleaded gasoline with an octanerating below 87. The use of these fuelscould result in engine damage that will notbe covered by the vehicle warranty.
For best overall vehicle and engineperformance, premium fuel with an octanerating of 91 or higher is recommended. Theperformance gained by using premium fuelis most noticeable in hot weather as wellas other conditions, for example whentowing a trailer. See Towing (page 50).
Do not be concerned if the enginesometimes knocks lightly. However, if theengine knocks heavily while using fuel withthe recommended octane rating, contactan authorized dealer to prevent any enginedamage.
We recommend Top Tier detergentgasolines, where available to help minimizeengine deposits and maintain optimalvehicle and engine performance. Foradditional information, refer towww.toptiergas.com.
Note:Use of any fuel for which the vehiclewas not designed can impair the emissioncontrol system, cause loss of vehicleperformance, and cause damage to theengine which may not be covered by thevehicle Warranty.
Do not use:
•Diesel fuel.
•Fuels containing kerosene or paraffin.
•Fuel containing more than 15% ethanolor E85 fuel.
•Fuels containing methanol.
•Fuels containing metallic-basedadditives, including manganese-basedcompounds.
•Fuels containing the octane boosteradditive, methylcyclopentadienylmanganese tricarbonyl (MMT).
•Leaded fuel, using leaded fuel isprohibited by law.
The use of fuels with metallic compoundssuch as methylcyclopentadienylmanganese tricarbonyl (commonly knownas MMT), which is a manganese-basedfuel additive, will impair engineperformance and affect the emissioncontrol system.
RUNNING OUT OF FUEL
WARNING: Flow of fuel througha fuel pump nozzle can produce staticelectricity. This can cause a fire if you arefilling an ungrounded fuel container.
Avoid running out of fuel because thissituation may have an adverse effect onengine components.
If you have run out of fuel:
•You may need to cycle the ignition fromoff to on several times after refuelingto allow the fuel system to pump thefuel from the tank to the engine. Onrestarting, cranking time will take a fewseconds longer than normal. Withkeyless ignition, just start the engine.Crank time will be longer than usual.
•Normally, adding 1 gal (4 L) of fuel isenough to restart the engine. If thevehicle is out of fuel and on a steepgrade, more than 1 gal (4 L) may berequired.
