Engine Oil
To ensure proper engine
performance and long life, careful
attention must be paid to engine oil.
Following these simple, but
important steps will help protect
your investment:
.Use engine oil approved to the
proper specification and of the
proper viscosity grade. See
“Selecting the Right Engine Oil”
in this section.
. Check the engine oil level
regularly and maintain the
proper oil level. See “Checking
Engine Oil” and“When to Add
Engine Oil” in this section.
. Change the engine oil at the
appropriate time. See Engine Oil
Life System 0241.

Engine Coolant
The cooling system in the vehicle is
filled with DEX-COOL®engine
coolant. See Maintenance Schedule
0 310 andRecommended Fluids
and Lubricants 0319.
The following explains the cooling
system and how to check and add
coolant when it is low. If there is a
problem with engine overheating,
see Engine Overheating 0247.
What to Use
{Warning
Adding only plain water or some
other liquid to the cooling system
can be dangerous. Plain water
and other liquids, can boil before
the proper coolant mixture will.
The 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
(Continued)
Warning (Continued)
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−37 °C (−34 °F), outside
temperature.
. Gives boiling protection up to
129 °C (265 °F), engine
temperature.
. Protects against rust and
corrosion.
. Will not damage aluminum parts.
. Helps keep the proper engine
temperature.
Caution
If improper coolant mixture,
inhibitors, or additives are used in
the vehicle cooling system, the
engine could overheat and be
damaged. Too much water in the
mixture can freeze and crack
engine cooling parts. The repairs
would not be covered by the
vehicle warranty. Use only the
proper mixture of engine coolant
for the cooling system. See
Recommended Fluids and
Lubricants 0319.
Never dispose of engine coolant by
putting it in the trash, pouring it on
the ground, or into sewers, streams,
or bodies of water. Have the coolant
changed by an authorized service
center, familiar with legal
requirements regarding used
coolant disposal. This will help
protect the environment and your
health.

Vehicle Care 245
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 recovery tank. If the
coolant inside the coolant recovery
tank is boiling, do not do anything
else until it cools down. If coolant is
visible but the coolant level is not at
or above the FULL COLD mark or
the FULL COLD ISO symbol mark,
add a 50/50 mixture of clean,
drinkable water and DEX-COOL
coolant at the coolant recovery tank,
but be sure the cooling system is
cool before this is done. SeeEngine
Overheating 0247.
The coolant recovery tank cap has
this symbol on it. When the engine is cold, the coolant
level should be at or above the
FULL COLD mark or the FULL
COLD ISO symbol mark on the
recovery tank.
When the engine is hot, the level
could be higher than the FULL
COLD mark or the FULL COLD ISO
symbol mark. If the coolant is below
the FULL COLD mark or the FULL
COLD ISO symbol mark when the
engine is hot, there could be a leak
in the cooling system.
If the coolant is low, add the coolant
or take the vehicle to your dealer for
service.
How to Add Coolant to the
Recovery Tank
{Warning
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. Do not spill
coolant on a hot engine.
Caution
This vehicle has a specific
coolant fill procedure. Failure to
follow this procedure could cause
the engine to overheat and be
severely damaged.
If recovery tank is empty, check the
coolant level in the radiator before
adding coolant to the recovery tank
or take the vehicle to the dealer for
service. See “How to Add Coolant to
the Radiator” later in this section.
If coolant is needed, add the proper
DEX-COOL coolant mixture at the
coolant recovery tank.
How to Add Coolant to the
Radiator
{Warning
Steam and scalding liquids from a
hot cooling system can blow out
and burn you badly. Never turn
the cap when the cooling system, (Continued)

Caution
After driving in the overheated
engine protection operating
mode, the engine oil will be
severely degraded. Any repairs
performed before the engine is
cool may cause engine damage.
Allow the engine to cool before
attempting any repair. Repair the
cause of coolant loss, change the
oil, and reset the oil life system.
SeeEngine Oil 0238.
Power Steering Fluid
The power steering fluid reservoir is
under the engine cover on the
passenger side of the vehicle. See
Engine Compartment Overview
0237 for reservoir location.
When to Check Power Steering
Fluid
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
To check the power steering fluid:
1. Turn the key off and let the engine compartment
cool down.
2. Remove the engine cover. See Engine Cover 0238.
3. Wipe the cap and the top of the reservoir clean.
4. Unscrew the cap and wipe the dipstick with a clean rag.
5. Replace the cap and completely tighten it.
6. Remove the cap again and look at the fluid level on the
dipstick. The fluid level should be
somewhere between the MAX and
MIN line on the dipstick in room
temperature. If the fluid is on or
below the MIN line, add fluid close
to the MAX line.
What to Use
To determine what kind of fluid to
use, see
Recommended Fluids and
Lubricants 0319. Always use the
proper fluid.
Caution
Use of the incorrect fluid may
damage the vehicle and the
damages may not be covered by
the vehicle warranty. Always use
the correct fluid listed in
Recommended Fluids and
Lubricants 0319.
Washer Fluid
What to Use
When adding windshield washer
fluid, be sure to read the
manufacturer's instructions before
