2005 Mercury Grand Marquis parking brake

Maintenance and Specificationschapter. If the light is blinking, engine
misfire is occurring which could damage your catalytic converter. Drive
in a moderate fashion (avoid heavy acceleration and deceleration) and
have your vehicle serviced immediately.
Under engine misfire conditions, excessive exhaust temperatures
could damage the catalytic converter, the fuel system, interior
floor coverings or other vehicle components, possibly causing a fire.
Electronic throttle control:
Illuminates when the engine has
defaulted to a ’limp-home’ operation.
Report the fault to a dealer at the
earliest opportunity.
Check fuel cap:Illuminates when
the fuel cap may not be properly
installed. Continued driving with
this light on may cause the Check
engine warning light to come on.
Refer toFuel filler capin theMaintenance and Specifications
chapter.
Brake system warning light:
•Standard instrument cluster
•Optional instrument cluster
To confirm the brake system
warning light is functional, it will
momentarily illuminate when the
ignition is turned to the ON position when the engine is not running, or
in a position between ON and START, or by applying the parking brake
when the ignition is turned to the ON position. If the brake system
warning light does not illuminate at this time, seek service immediately
from your dealership. Illumination after releasing the parking brake
indicates low brake fluid level and the brake system should be inspected
immediately by your servicing dealership.

Replacing front parking/cornering/turn signal lamp bulbs
The park/turn/cornering lamp bulbs can be replaced without removing
the headlamp assembly.
1. Make sure headlamp switch is in OFF position, then open the hood.
2. Remove the three pin type retainers and the radiator shield.
3. Loosen the parking lamp attachments, on the back side of the lamp,
and pull the lamp assembly forward.
4. Remove the bulb from the side turn lamp assembly.
5. Disconnect the electrical connector from the bulb and replace the
bulb.
Note:The parking lamp/turn signal bulbs should not be removed from
the lamp until just before a replacement bulb is installed. Removing the
bulb for an extended period of time may affect headlamp bulb
performance. Contaminants may enter the headlamp where they can
settle on the lens and reflector. Never turn the lamps on with the bulb
removed.
6. To install, reverse the order of the removal procedure.
Replacing tail lamp/brake/turn lamp bulbs
The tail lamp, the brake lamp and the turn signal lamp bulbs are located
in the tail lamp assembly. Follow the same steps to replace either bulb.
1. Make sure headlamp switch is in
OFF position, then open the trunk
and remove plastic retainer to
expose the lamp assembly hardware.
2. Carefully pull the carpet away to
expose the plastic retainer.
3. Remove three nut and washer
assemblies and the lamp assembly
from the vehicle.

Reasons given... Consider...
“I have an airbag” Airbags offer greater protection when
used with safety belts. Frontal airbags
are not designed to inflate in rear and
side crashes or rollovers.
“I’d rather be thrown clear” Not a good idea.Peoplewho are
ejected are 40 times more likely
to DIE.Safety belts help prevent
ejection, WE CAN’T “PICK OUR
CRASH”.
Do not sit on top of a buckled safety belt to avoid the
BeltMinder
chime. Sitting on the safety belt will increase the
risk of injury in an accident. To disable (one-time) or deactivate the
BeltMinder
feature please follow the directions stated below.
One time disable
If at any time the driver/front passenger quickly buckles then unbuckles
the BeltMinder
feature for that seating position, the BeltMinder
is
disabled for the current ignition cycle. The BeltMinder
feature will
re-enable during the same ignition cycle if the occupant buckles and
remains buckled for approximately 30 seconds. Confirmation is not given
for the one time disable.
Deactivating/activating the BeltMinderfeature
The driver and front passenger BeltMinder
are
deactivated/activated independently. When deactivating/activating
one seating position, do not buckle the other position as this will
terminate the process.
Read Steps1-4thoroughly before proceeding with the
deactivation/activation programming procedure.
Note: The driver and front passenger BeltMinder
features must be
disabled/enabled separately. Both cannot be disable/enabled during the
same key cycle.
The driver and front passenger BeltMinder
features can be
deactivated/activated by performing the following procedure:
Before following the procedure, make sure that:
•The parking brake is set

service as soon as possible.
Tire change procedure
To help prevent the vehicle from moving when you change a tire,
be sure the parking brake is set, then block (in both directions)
the wheel that is diagonally opposite (other side and end of the
vehicle) to the tire being changed.
If the vehicle slips off the jack, you or someone else could be
seriously injured.

If you smell exhaust fumes inside your vehicle, have your dealer
inspect your vehicle immediately. Do not drive if you smell
exhaust fumes.
Important safety precautions
A computer system controls the engine’s idle revolutions per minute
(RPM). When the engine starts, the idle RPM runs higher than normal in
order to warm the engine. If the engine idle speed does not slow down
automatically, have the vehicle checked. Do not allow the vehicle to idle
for more than 10 minutes at the higher engine RPM.
Before starting the vehicle:
1. Make sure all vehicle occupants have buckled their safety belts. For
more information on safety belts and their proper usage, refer to the
Seating and Safety Restraintschapter.
2. Make sure the headlamps and vehicle accessories are off.
3. Make sure the gearshift is in P
(Park).
4. Make sure the parking brake is
set.

The ABS operates by detecting the
onset of wheel lockup during brake
applications and compensates for
this tendency. The wheels are
prevented from locking even when
the brakes are firmly applied. The
accompanying illustration depicts
the advantage of an ABS equipped
vehicle (on bottom) to a non-ABS
equipped vehicle (on top) during hard braking with loss of front braking
traction.
Using ABS
•In an emergency or when maximum efficiency from the four-wheel
ABS is required, apply continuous force on the brake. The four wheel
ABS will be activated immediately, thus allowing you to retain steering
control of your vehicle and, providing there is sufficient space, will
enable you to avoid obstacles and bring the vehicle to a controlled
stop.
•The anti-lock system does not reduce stopping distance. Always leave
enough room between your vehicle and the vehicle in front of you to
stop.
•We recommend that you familiarize yourself with this braking
technique. However, avoid taking any unnecessary risks.
ABS warning lamp
The ABS warning lamp in the
instrument cluster momentarily
illuminates when the ignition is
turned on. If the light does not
illuminate momentarily at start up,
remains on or continues to flash, the ABS needs to be serviced.
With the ABS light on, the anti-lock
brake system is disabled and normal
braking is still effective unless the
brake warning light also remains
illuminated with parking brake
released. (If your brake warning lamp illuminates, have your vehicle
serviced immediately.)
