Warning (Continued)
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. 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 0331.
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.
Checking Coolant
The vehicle must be on a level surface
when checking the coolant level. It is normal to see coolant moving in
the upper coolant hose return line
when the engine is running. It is also
normal to see bubbles entering the
surge tank through the small hose.
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 at or above the COLD FILL
line, add a 50/50 mixture of clean
drinkable water and DEX-COOL
coolant.
Be sure the cooling system is cool
before this is done.
It is normal for the coolant level in
the bottom chamber to rise and fall
with operating temperature and
ambient conditions. Coolant will
evaporate from the bottom chamber
in normal operation. This will happen
faster when the vehicle is driven for
long periods in hot, dry conditions.

266 VEHICLE CARE
If no coolant is visible in the coolant
surge tank, add coolant as follows:
How to Add Coolant to the
Coolant Surge TankCaution
This vehicle has a specific coolant
fill procedure. Failure to follow this
procedure could cause the engine to
overheat and be severely damaged.
If no problem is found, check to see if
coolant is visible in the coolant surge
tank. If coolant is visible but the
coolant level is not at the bottom of
the fill neck, add a 50/50 mixture of
clean, drinkable water and DEX-COOL
coolant at the coolant surge tank, but
be sure the cooling system, including
the coolant surge tank pressure cap, is
cool before you do it.
{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,
including the surge tank pressure
cap, is hot. Wait for the cooling
system and surge tank pressure cap
to cool.
{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 could catch
fire and you or others could be (Continued)
Warning (Continued)
burned. Use a 50/50 mixture of
clean, drinkable water and
DEX-COOL coolant.
Caution
In cold weather, water can freeze
and crack the engine, radiator,
heater core, and other parts. Use
the recommended coolant and the
proper coolant mixture.
{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.
1. Remove the coolant surge tank pressure cap from the top
chamber when the cooling

324 SERVICE AND MAINTENANCE
At your dealer, you can be certain that
you will receive the highest level of
service available. Your dealer has
specially trained service technicians,
uses genuine replacement parts, as
well as, up-to-date tools and
equipment to ensure fast and accurate
diagnostics.
The proper replacement parts, fluids,
and lubricants to use are listed in
Recommended Fluids and Lubricants
0331 and Maintenance Replacement
Parts 0332. We recommend the use
of genuine parts from your dealer.
Rotation of New Tires
Tire rotation is not recommended if
the vehicle has different size tires on
the front and rear wheels. If tire
rotation is recommended for the
vehicle, to maintain ride, handling,
and performance of the vehicle, it is
important that the first rotation
service for new tires be performed.
Tires should be rotated every service.
See Tire Rotation 0296.Maintenance Schedule
Owner Checks and Services
At Each Fuel Stop
.
Check the engine oil level. See
Engine Oil 0257.
Once a Month
. Check the tire inflation pressures.
See Tire Pressure 0290.
. Inspect the tires for wear. See Tire
Inspection 0296.
. Check the windshield washer fluid
level. See Washer Fluid 0269.
Engine Oil Change
Change the engine oil and filter when
the CHANGE ENGINE OIL SOON
message displays, 12 000 km/7,500 mi,
or at one year, whichever comes first.
If driven under the best conditions,
the engine oil life system may not
indicate the need for vehicle service
for up to a year. The engine oil and
filter must be changed at least once a
year and the oil life system must be
reset. Your trained dealer technician
can perform this work. If the engine oil life system is reset accidentally,
service the vehicle within 5 000 km/
3,000 mi since the last service. Reset
the oil life system when the oil is
changed. See
Engine Oil Life
System 0259.
Tire Rotation and Required
Services Every 12 000 km/
7,500 mi
Rotate the tires, if recommended for
the vehicle, and perform the following
services. See Tire Rotation0296.
. Check engine oil level and oil
life percentage. If needed, change
engine oil and filter, and reset oil
life system. See Engine Oil0257
and Engine Oil Life System 0259.
. Check engine coolant level. See
Engine Coolant 0264.
. Check windshield washer fluid
level. See Washer Fluid 0269.
. Visually inspect windshield wiper
blades for wear, cracking,
or contamination. See Exterior
Care 0315. Replace worn or
damaged wiper blades. See Wiper
