What to Use
{WARNING:
Adding only plain water to the cooling system can
be dangerous. Plain water, or some other liquid
such as alcohol, can boil before the proper
coolant mixture will. The vehicle's coolant warning
system is set for the proper coolant mixture. With
plain water or the wrong mixture, the engine could
get too hot but you would not get the overheat
warning. The engine could catch fire and you or
others could be burned. Use a 50/50 mixture of
clean, drinkable water and DEX-COOL
®coolant.
Use a 50/50 mixture of clean, drinkable water and
DEX-COOL
®coolant. If using this mixture, nothing else
needs to be added. This mixture:
.Gives freezing protection down to −34°F (−37°C),
outside temperature.
.Gives boiling protection up to 265°F (129°C),
engine temperature.
.Protects against rust and corrosion.
.Will not damage aluminum parts.
.Helps keep the proper engine temperature. Notice:
If an improper coolant mixture is used, the
engine could overheat and be badly damaged. The
repair cost would not be covered by the vehicle
warranty. Too much water in the mixture can freeze
and crack the engine, radiator, heater core, and
other parts.
Notice: If extra inhibitors and/or additives are used
in the vehicle's cooling system, the vehicle could be
damaged. Use only the proper mixture of the engine
coolant listed in this manual for the cooling system.
See Recommended Fluids and Lubricants
on
page 7‑12for more information.
Checking Coolant
The vehicle must be on a level surface when checking
the coolant level.
Check to see if coolant is visible in the coolant surge
tank. If the coolant inside the coolant surge tank is
boiling, do not do anything else until it cools down.
If coolant is visible but the coolant level is not between
the Minimum and Maximum marks, add a 50/50 mixture
of clean, drinkable water and DEX-COOL
®coolant at
the coolant surge tank, but be sure the cooling system
is cool before this is done. See Engine Coolant
on
page 6‑25for more information.

4. With the coolant surge tank pressure cap off, startthe engine and let it run until you can feel the
upper radiator hose getting hot. Watch out for the
engine cooling fan.
By this time, the coolant level inside the coolant
surge tank may be lower. If the level is lower than
the Maximum mark, add more of the proper
mixture to the coolant surge tank until the level
reaches the mark.
5. Replace the pressure cap. Be sure the pressure cap is hand-tight and fully seated.
Notice: If the pressure cap is not tightly installed,
coolant loss and possible engine damage may
occur. Be sure the cap is properly and tightly
secured.
Engine Overheating
The vehicle has an indicator to warn of the engine
overheating.
There is a coolant temperature gage on the instrument
panel cluster. See Engine Coolant Temperature Gage
on page 4‑28.
You may decide not to lift the hood when this warning
appears, but instead get service help right away. See
Roadside Assistance Program on page 8‑6.
If you do decide to lift the hood, make sure the vehicle
is parked on a level surface. Then check to see if the engine cooling fan is running.
If the engine is overheating, the fan should be running.
If it is not, do not continue to run the engine and have
the vehicle serviced.
Notice:
Engine damage from running the engine
without coolant is not covered by the warranty.
Notice: If the engine catches fire because of being
driven with no coolant, your vehicle can be badly
damaged. The costly repairs would not be covered
by the vehicle warranty.
If Steam Is Coming From The Engine
Compartment
{WARNING:
Steam from an overheated engine can burn you
badly, even if you just open the hood. Stay away
from the engine if you see or hear steam coming
from it. Just turn it off and get everyone away from
the vehicle until it cools down. Wait until there is
no sign of steam or coolant before you open
the hood.

Power Steering Fluid
When to Check Power Steering Fluid
The power steering fluid reservoir is located toward the
front of the engine compartment on the driver's side of
the vehicle. SeeEngine Compartment Overview
on
page 6‑14for reservoir location.
It is not necessary to regularly check power steering
fluid unless you suspect there is a leak in the system or
you hear an unusual noise. A fluid loss in this system
could indicate a problem. Have the system inspected
and repaired.
How to Check Power Steering Fluid
Turn the key off and let the engine compartment
cool down.
The level should be between the MIN (B) and MAX (A)
marks on the reservoir. If the level drops below the
MIN (B) mark, add power steering fluid. Do not overfill
the reservoir and remember to replace the cap tightly
when you are finished and clean up any spilled fluid.

4. Open the hoods and locate the batteries. Find thepositive (+) and negative (−) terminal locations on
each vehicle. See Engine Compartment Overview
on page 6‑14for more information on location.
{WARNING:
An electric fan can start up even when the engine
is not running and can injure you. Keep hands,
clothing and tools away from any underhood
electric fan.
{WARNING:
Using a match near a battery can cause battery
gas to explode. People have been hurt doing this,
and some have been blinded. Use a flashlight if
you need more light.
Be sure the battery has enough water. You do not
need to add water to the battery installed in your
new vehicle. But if a battery has filler caps, be
(Continued)
WARNING: (Continued)
sure the right amount of fluid is there. If it is low,
add water to take care of that first. If you don't,
explosive gas could be present.
Battery fluid contains acid that can burn you. Do
not get it on you. If you accidentally get it in your
eyes or on your skin, flush the place with water
and get medical help immediately.
{WARNING:
Fans or other moving engine parts can injure you
badly. Keep your hands away from moving parts
once the engine is running.
5. Check that the jumper cables do not have loose or missing insulation. If they do, you could get a
shock. The vehicles could be damaged too.
Before you connect the cables, here are some
things you should know. Positive (+) will go to
positive (+) or to a remote positive (+) terminal if

Rotation of New Tires
To maintain ride, handling, and performance of the
vehicle, it is important that the first rotation service for
new tires be performed when they have 8 000 to
13 000 km (5,000 to 8,000 miles). See Tire Inspection
and Rotation on page 6‑61.
Scheduled Maintenance
When the Change Engine Oil Light
Displays
Change engine oil and filter. See Engine Oilon
page 6‑15. An Emission Control Service.
When the change engine oil light displays, service is
required for the vehicle as soon as possible, within the
next 1 000 km/600 miles. If driving under the best
conditions, the engine oil life system might not indicate
the need for vehicle service for more than a year. The engine oil and filter must be changed at least once a
year and the oil life system must be reset. Your dealer/
retailer has trained service technicians who will perform
this work and reset the system. If the engine oil life
system is reset accidentally, service the vehicle within
5 000 km/3,000 miles since the last service. Reset the
oil life system whenever the oil is changed. See
Engine
Oil Life System on page 6‑18.
When the change engine oil light displays, certain
services, checks, and inspections are required. The
services described for Maintenance Ishould be
performed at every engine oil change. The services
described for Maintenance IIshould be
performed when:
.Maintenance Iwas performed the last time the
engine oil was changed.
.It has been 10 months or more since the change
engine oil light has displayed or since the last
service.
