Keep the hood and front air inlet free of ice, snow or
any other obstruction (such as leaves). The heater
and defroster
will work far better, reducing the
chance of fogging the inside of the windows.
When you enter a vehicle in cold weather, adjust the
fan to the highest speed for a few moments before
driving
off. This helps clear the intake ducts of snow
and moisture, and reduces the chance of fogging the
inside of the windows.
Keep the
air path under the front seats clear of
objects. This helps circulate air throughout
your vehicle.

Downloaded from www.Manualslib.com manuals search engine Run your engine only as long as you must. This saves
fuel. When you run the engine, make it go a little faster
than just idle. That is, push the accelerator slightly. This
uses less fuel for the heat that you get and it keeps the
battery charged. You will need a well-charged battery to
restart the vehicle, and possibly for signaling later on
with your headlamps. Let the heater run for awhile.
Then, shut the engine off and close the window almost
all the way to preserve the heat. Start the engine again
and repeat this only when you feel really uncomfortable
from the cold. But
do it as little as possible. Preserve the
fuel as long as you can. To help keep warm, you can get
out
of the vehicle and do some fairly vigorous exercises
every half hour or
so until help comes.

Two labels on your vehicle show how much weight it
may properly carry. The Tire-Loading Information label
found on the driver's door tells you the proper size,
speed rating and recommended inflation pressures for
the tires on your vehicle. It also gives you important
information about the number
of people that can be in
your vehicle and the total weight that you can carry.
This weight is called the Vehicle Capacity Weight and
includes the weight of all occupants, cargo and all
options not installed in the factory.

Downloaded from www.Manualslib.com manuals search engine If it isn’t, the coolant level should be indicated by a
CHECK COOLANT LEVEL message on the Driver
Information Center. If it is, you may have a leak in the
radiator hoses, heater hoses, radiator, water pump or
somewhere else in the cooling system. Heater and radiator
hoses, and other engine
parts, can be very hot. Don’t touch them.
If you
do, you can be burned.
Don’t run the engine if there
is a leak. If you run
the engine, it could lose all coolant. That could
cause an engine fire, and you could be burned.
Get any leak fixed before you drive the vehicle.
ICE:
Engine damage if you keep running your engine
without coolant isn’t covered by your warranty.
See “Overheated Engine Protection Operating
Mode” in the Index.
If there
seems to be no leak, with the engine on, check to
see if the electric engine fans are running.
If the engine
is overheating, both fans should be running. If they
aren’t, your vehicle needs service.

Downloaded from www.Manualslib.com manuals search engine NOTICE:
In cold weather, water can freeze and crack the
engine, radiator, heater core and other parts.
So
use the recommended coolant.
I
You can be burned if you spill coolant on hot
engine parts. Coolant contains ethylene glycol
and it will burn
if the engine parts are hot
enough. Don’t spill coolant on
a hot engine.
1. You can remove the coolant surge tank pressure cap
when the cooling system, including the coolant surge
tank pressure cap and upper radiator hose, is no
longer hot. Turn the pressure cap slowly
counterclockwise
until it first stops. (Don’t press
down while turning the pressure cap.)
If you hear a hiss, wait for that to ston A hiss means
there is still some pressure left.

Change Indicator
Your vehicle is equipped with a transaxle fluid change
indicator.
A CHANGE TRANS FLUID message will
display
on the Driver Information Center (DIC) when
the powertrain computer determines
that the transaxle
fluid needs to be changed or at each
100,000 miles
(160 000 km) interval, whichever occurs first. When
this message appears, change the transaxle fluid and
reset
the transaxle fluid life indicator as follows:
1. Turn the ignition on but do not start the engine.
2. Press and hold the OFF and rear defog buttons on the
climate control at the same time until the
TRANS
FLUID RESET message appears on the DIC.
Engine Coolant
The cooling s stem in your vehicle is filled with
DEX-COOL engine coolant. This coolant is designed
to remain
in your vehicle for 5 years or 150,000 miles
(240 000 km) whichever occurs first, if you add only
DEX-COOL’ extended life coolant.
The following explains your cooling system and how
to add coolant when it is low. If you have a problem
with engine overheating, see “Engine Overheating” in
the Index.
J
A 50/50 mixture of water and DEX-COOL@
coolant will:
Give freezing protection down to -34°F (-37°C).
Give boiling protection up to 265 “F (129°C).
Protect against rust and corrosion.
Help keep the proper engine temperature.
Let the warning lights and gages work as
they should.
NOTICE: ~ ~~ ~ -
When adding coolant, it is important that you
use only
DEX-COOL@ (silicate-free) coolant.
If coolant other than DEX-COOL@ is added to
the system, premature engine, heater core or
radiator corrosion may result. In addition, the
engine coolant will require change sooner
-- at
30,000 miles (50 000 km) or 24 months,
whichever occurs first. Damage caused by the use
of coolant other than DEX-COOL@ is not
covered by your new vehicle warranty.

Downloaded from www.Manualslib.com manuals search engine What to Use
Use a mixture of one-half clean water (preferably
distilled) and one-half
DEX-COOL@ coolant which
won’t damage aluminum
parts. If you use this mixture,
you don’t need to add anything else.
Adding only plain water to your cooling system
can be dangerous. Plain water, or some other
liquid like alcohol, can boil before the proper coolant
mix will. Your vehicle’s coolant warning
system is set for the proper coolant mix. With
plain water or the wrong mix, your engine could
get too hot but you wouldn’t get the overheat
warning. Your engine could catch fire and you or
others could be burned. Use a
50/50 mix of clean
water and
DEX-COOL@ coolant.
I NOTICE:
If you use an improper coolant mix, your engine
could overheat and be badly damaged. The
repair cost wouldn’t be covered by your
warranty.
Too much water in the mix can freeze
and crack the engine, radiator, heater core and
other parts.
If you have to add coolant more than four times a year,
have your dealer check your cooling system.
I NOTICE:
If you use the proper coolant, you don’t have to
add extra inhibitors or additives which claim to
improve the system. These can be harmful.
