SecuriLockYanti-theft system
This light indicates the anti-theft
alarm system is armed. Refer to
Anti-theft systemin theControls
and featureschapter. Momentarily
illuminates when the ignition is
turned to ON/START. If the light
fails to illuminate, continues to
flash or remains on, have the
system serviced. Refer to
SecuriLockyanti-theft systemin
theControls and features
chapter.
Charging system
Momentarily illuminates when the
ignition is turned ON and the
engine is off. The light also
illuminates when the battery is not
charging properly, requiring
electrical system service.
Oil pressure/Engine coolant
This light will come on when the
key is in the ON position and the:
²engine coolant temperature is
very high
²engine oil pressure is low
The light serves as a notice that a
system needs your attention and to
check the engine coolant
temperature gauge and the engine
oil pressure gauge.

the reserve fuel.
Speedometer
Indicates the current vehicle
speed.
Engine coolant temperature
gauge
Indicates the temperature of the
engine coolant. At normal
operating temperature, the needle
remains within the normal area
(the area between the ªHº and
ªCº). If it enters the red section,
the engine is overheating. Stop the
vehicle, switch off the ignition and
let the engine cool. Refer to
Engine coolantin the
Maintenance and carechapter.
Never remove the coolant
recovery cap while the
engine is running or hot.
This gauge indicates the
temperature of the engine coolant,
not the coolant level. If the coolant
is not at its proper level or
mixture, the gauge indication will
not be accurate.

apply the brake and release the
parking brake.
Using the engine block heater
(if equipped)
An engine block heater warms the
engine coolant, which improves
starting, warms up the engine
faster and allows the
heater-defroster system to respond
quickly. They are strongly
recommended if you live in a
region where temperatures reach
-23ÉC (-10ÉF) or below.
For best results, plug the heater in
at least three hours before starting
the vehicle. Using the heater for
longer than three hours will not
harm the engine, so the heater can
be plugged in the night before
starting the vehicle.
To prevent electrical
shock, do not use your
heater with ungrounded
electrical systems or
two-pronged (cheater) adapters.
Guarding against exhaust
fumes
Although odorless and colorless,
carbon monoxide is present in
exhaust fumes. Take precautions
to avoid its dangerous effects.
Starting

container to ensure the coolant
concentration in your vehicle is
such that the coolant will not
freeze at the temperature level in
which you drive during winter
months. Never increase the engine
coolant concentration above 60%.
Leave a 50/50 mixture of engine
coolant and water in your vehicle
year-round in non-extreme
climates.
What you should know about
fail-safe cooling
If the engine coolant supply is
depleted, this feature allows the
vehicle to be driven temporarily
before incremental component
damage is incurred. The ªfail safeº
distance depends on ambient
temperatures, vehicle load and
terrain.
How fail-safe cooling works
If the engine overheats, the engine
will automatically switch from
eight to alternating four cylinder
operation. Each disabled cylinder
acts as an air pump and cools the
engine.
When this occurs, the engine
coolant temperature gauge will
move into the red area and the
light illuminates.
The check engine light will
illuminate, indicating that vehicle
service is required.
The vehicle will still operate, but
will have limited engine power and

no air conditioning capability.
Continued operation will increase
engine temperature and cause the
engine to completely shut down.
The vehicle will coast to a stop.
As the engine temperature cools,
the engine may be re-started. Take
your vehicle to a service facility as
soon as possible to minimize
engine damage.
When fail-safe mode is
activated
²Pull off the road as soon as
possible.
²Immediately turn the engine off
to prevent severe engine
damage.
²Wait for the engine to cool.
²Check the coolant level.
CHECKING AND ADDING
POWER STEERING FLUID
Check the power steering fluid at
least twice a year. If adding fluid is
necessary, use only MERCONt
ATF power steering fluid.
1. Start the engine and let it run
until it reaches normal operating
temperature (the engine coolant
temperature gauge will be near the
center of the NORMAL band).
