Vehicle Care 241
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
Lubricants0301.
Never dispose of engine coolant by
putting it in the trash, pouring it on
the ground, or pouring 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.
The engine coolant surge tank and
CAC bottle are in the engine
compartment on the driver side of
the vehicle. See Engine
Compartment Overview 0230.
Check to see if coolant is visible in
the surge tank and CAC bottle.
If the coolant inside the 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 mark pointed to on the
surge tank or at the CAC bottle
COLD FILL mark, add a
50/50 mixture of clean, drinkable
water and DEX-COOL coolant.
Be sure the cooling system is cool
before this is done. If no coolant is visible in the coolant
surge tank or CAC bottle, add
coolant as follows:
How to Add Coolant to the
Surge 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.

Service and Maintenance 297
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 inRecommended Fluids and
Lubricants 0301 andMaintenance
Replacement Parts 0302. 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 0269.Maintenance
Schedule
When the Change Engine Oil
Soon Message Displays
Change engine oil and filter. See
Engine Oil 0234. An Emission
Control Service.
When the CHANGE ENGINE OIL
SOON message 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
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 dealer 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.
