Optional instrument cluster gauges
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 as
soon as safely possible, switch off
the engine immediately and let the
engine cool. Refer toEngine
coolantin theMaintenance and
carechapter.
Never remove the coolant reservoir cap while the engine is
running or hot.

this warning message is displayed, check the level of the engine oil.
Refer toEngine oilin theMaintenance and carechapter for
information about adding engine oil.
CHECK ENGINE TEMP.Displayed when the engine coolant is
overheating. Stop the vehicle as soon as safely possible, turn off the
engine and let it cool. Check the coolant and coolant level. Refer to
Engine coolantin theMaintenance and carechapter. If the warning
stays on or continues to come on, contact your dealer as soon as safely
possible.
CHECK CHARGING SYSTEM.Displayed when the electrical system is
not maintaining proper voltage. If you are operating electrical accessories
when the engine is idling at a low speed, turn off as many of the
electrical loads as soon as possible. If the warning stays on or comes on
when the engine is operating at normal speeds, have the electrical
system checked as soon as possible.
TRANSMISSION OVERHEATED.Indicates the transmission is
overheating. This warning may appear when towing heavy loads or when
driving in a low gear at a high speed for an extended period of time.
Stop the vehicle as soon as safely possible, turn off the engine and let it
cool. Refer toTransmission fluidin theMaintenance and care
chapter. If the warning stays on or continues to come on, contact your
dealer for transmission service as soon as possible.

Cold weather starting (flexible fuel vehicles only)
As the outside temperature approaches freezing, ethanol fuel distributors
should supply winter grade ethanol (same as with unleaded gasoline). If
summer grade ethanol is used in cold weather conditions, you may
experience increased cranking times, rough idle or hesitation until the
engine has warmed up. Consult your fuel distributor for the availability of
winter grade ethanol.
Do not crank the engine for more than 30 seconds at a time as starter
damage may occur. If the engine fails to start, turn the key to OFF and
wait 30 seconds before trying again.
Do not use starting fluid such as ether in the air intake system (see Air
Cleaner Decal). Such fluid could cause immediate explosive damage to
the engine and possible personal injury.
If you should experience cold weather starting problems on ethanol, and
neither an alternative brand of ethanol nor an engine block heater is
available, the addition of unleaded gasoline to your tank will improve
cold starting performance. Your vehicle is designed to operate on ethanol
alone, unleaded gasoline alone, or any mixture of the two.
SeeChoosing the right fuelin theMaintenance and carechapter for
more information on diesel fuel.
If the engine fails to start using the preceding instructions
1. Press the accelerator pedal 1/3 to 1/2 of the way to floor and hold.
2. Turn the key to START position.
3. When the engine starts, release the key, then release the accelerator
pedal gradually as the engine speeds up.
4. If the engine still fails to start, repeat steps one through three.
5. After the engine starts, hold your foot on the brake pedal, put the
gearshift lever in gear and release the parking brake. Slowly release the
brake pedal and drive away in a normal manner.
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. Use of an engine block heater is strongly
recommended if you live in a region where temperatures reach -23ÉC
(-10ÉF) or below.

Severe climates
If you drive in extremely cold climates (less than ±36É C [±34É F]), it
may be necessary to increase the coolant concentration above 50%.
Refer to the chart on the coolant container to ensure the coolant
concentration in your vehicle will provide adequate freeze protection.
Never increase the engine coolant concentration above 60%
(protection to ±60ÉF). At a level over 60%, your engine could overheat
and become damaged.
If you drive in extremely hot climates, it is still necessary to maintain the
coolant concentration at 50/50 coolant and water.Do not allow the
coolant concentration to fall below 40% coolant.At a concentration
less than 40%, the corrosion protection to your engine and cooling
components may be compromised and permanent damage may result.
What you should know about fail-safe cooling
(4.6L V8 engine only)
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 begins to overheat:
²the engine coolant temperature
gauge will move to the red (hot)
area.
²the
and thesymbol
will illuminate.
²theService Engine Soon
indicator light will illuminate.
If the engine reaches a preset over-temperature condition, the engine
will automatically switch to alternating cylinder operation. Each disabled
cylinder acts as an air pump and cools the engine.
When this occurs the vehicle will still operate. However:
²the engine power will be limited.
²the air conditioning system will be disabled.
Maintenance and care
246

Continued operation will increase the engine temperature:
²the engine will completely shut down.
²steering and braking effort will increase.
Once the engine temperature cools, the engine can be re-started. Take
your vehicle to a service facility as soon as possible to minimize engine
damage.
When fail-safe mode is activated
You have limited engine power when in the fail-safe mode, so drive the
vehicle with caution. The vehicle will not be able to maintain high speed
operation and the engine will run rough. Remember that the engine is
capable of completely shutting down automatically to prevent engine
damage, therefore:
1. Pull off the road as soon as safely possible and turn off the engine.
2. Arrange for the vehicle to be taken to a service facility.
3. If this is not possible, wait a short period for the engine to cool.
4. Check the coolant level and replenish if low.
Never remove the coolant reservoir cap while the engine is
running or hot.
5. Re start the engine and take your vehicle to a service facility.
Driving the vehicle without repairing the engine problem
increases the chance of engine damage. Take your vehicle to a
service facility as soon as possible.
CHECKING AND ADDING POWER STEERING FLUID
Check the power steering fluid. Refer to the scheduled maintenance
guide for the service interval schedules. If adding fluid is necessary, use
only MERCONtAT F.
Maintenance and care
247

²4.0L SOHC V6 engine
²4.6L V8 engine
1. Start the engine and let it run until it reaches normal operating
temperature (the engine coolant temperature gauge indicator will be
near the center of the normal area between H and C).
2. While the engine idles, turn the steering wheel left and right several
times.
3. Turn the engine off.
4. Check the fluid level in the reservoir.
5. The fluid level should be between the MIN and MAX lines. Do not add
fluid if the level is in this range.
6. If the fluid is low, add fluid in small amounts, continuously checking
the level until it reaches the correct operating range. Be sure to put the
cap back on the reservoir.
