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.

ENGINE OIL
Checking the engine oil
Check the engine oil each time you
fuel your vehicle.
1. Make sure the vehicle is on level
ground.
2. Turn the engine off and wait a
few minutes for the oil to drain
into the oil pan.
3. Set the parking brake and
ensure the gearshift is securely
latched in P (Park).
4. Open the hood. Protect yourself
from engine heat.

WINDSHIELD WASHER FLUID
Checking and adding washer
fluid
Check the washer fluid whenever
you stop for fuel. The reservoir is
highlighted with a
symbol.
If the level is low, add enough fluid
to fill the reservoir. In very cold
weather, do not fill the reservoir all
the way.
Do not put engine coolant
in the container for the
windshield washer fluid.
Checking and adding washer
fluid for the liftgate
Washer fluid for the liftgate is
supplied by the same reservoir as
the windshield.
ENGINE COOLANT
Check the level of the coolant in
the reservoir at least once a
month. Be sure to read and
understandPrecautions when
servicing your vehiclein this
chapter.
If the engine coolant has not been
checked for a long period of time,
the engine coolant reservoir may

eventually empty. If this occurs,
add engine coolant to the coolant
reservoir. For more information on
engine coolant maintenance, refer
toAdding engine coolantin this
chapter.
Automotive fluids are not
interchangeable; do not use engine
coolant, antifreeze or windshield
washer fluid outside of its specified
function and vehicle location.
Adding engine coolant
Do not put engine coolant
in the container for the
windshield washer fluid.
If sprayed on the windshield,
engine coolant could make it
difficult to see through the
windshield.
When the engine is cool, add a
50/50 mixture of engine coolant
and water to the engine coolant
recovery reservoir-DO NOT ADD
DIRECTLY TO THE RADIATOR.
Add straight water only in an
emergency, but you should replace
it with a 50/50 mixture of coolant
and distilled water as soon as
possible.
Check the coolant level in the
coolant recovery reservoir the next
few times you drive the vehicle. If
necessary, add enough of a 50/50
mixture of coolant and water to
bring the liquid level to the fill line
on the reservoir.
Maintenance and care

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).
