Essential Information
Location of Spare Tire and ToolsYour vehicle is equipped with a temporary spare tire which
is smaller than a regular tire and designed for emergency use only. The jack, spare tire, jack handle andlug nut wrench are under the cargo cover in the trunk of the vehicle.
FusesIf your electrical components aren’t working properly, a fuse may have blown. For more
information, please consult your Owner’s Guide.
Fuel Pump Shutoff SwitchThis device stops the electric fuel pump from sending fuel to the
engine when your vehicle has had a substantial jolt. After an accident, if the engine cranks but doesnot start, this switch may have been activated. The fuel pump shutoff switch is located in the front
passenger footwell area in the right upper corner.
Unleaded Fuel RecommendationsFor optimum performance use “Regular” unleaded fuel
with a pump (R+M)/2 octane rating of at least 87. We do not recommend the use of gasolines labeled
as “Regular” with octane ratings of 86 or lower that are sold in high altitude areas.
Tire PressureSafe operation of your Montego requires that your tires be properly inflated. The
Mercury recommended inflation pressure is found on the Tire Label or the Certification Label locatednear the front door latch on the driver’s side. At least once a month and before long trips, inspect eachtire and check the air pressure with a tire gauge. Don’t forget the spare. Air pressure should be checked
when the tires are cold. Inflate all tires to the inflation pressure recommended by Ford Motor Company.
