Maintenance

ENGINE COOLANT CHECK
WARNING: Do not remove the
coolant reservoir cap when the engine is
on or the cooling system is hot. Wait 10
minutes for the cooling system to cool
down. Cover the coolant reservoir cap with
a thick cloth to prevent the possibility of
scalding and slowly remove the cap.
Failure to follow this instruction could result
in personal injury.
WARNING: Do not put coolant in the
windshield washer reservoir. If sprayed on
the windshield, coolant could make it
difficult to see through the windshield.
WARNING: To reduce the risk of
personal injury, make sure the engine is
cool before unscrewing the coolant
pressure relief cap. The cooling system is
under pressure. Steam and hot liquid can
come out forcefully when you loosen the
cap slightly.When the engine is cold, check the
concentration and level of the coolant at the
intervals listed in the scheduled maintenance
information. See Scheduled Maintenance
(page 579).
Note:Make sure that the coolant level is
between the MIN and the MAX marks on
the coolant reservoir.
Note: Coolant expands when it is hot. The
level may extend beyond the MAX mark.
Maintain coolant concentration within 48%
to 50%, which equates to a freeze point
between -29°F (-34°C) and -35°F (-37°C).
Coolant concentration should be checked
using a refractometer. We do not recommend
the use of hydrometers or coolant test strips
for measuring coolant concentration.Adding Coolant
WARNING: Do not add coolant
further than the MAX mark.
WARNING: Do not add coolant when
the vehicle is on or the cooling system is
hot. Failure to follow this instruction could
result in personal injury.
WARNING: Do not remove the
coolant reservoir cap when the engine is
on or the cooling system is hot. Wait 10
minutes for the cooling system to cool
down. Cover the coolant reservoir cap with
a thick cloth to prevent the possibility of
scalding and slowly remove the cap.
Failure to follow this instruction could result
in personal injury.
WARNING: Do not put coolant in the
windshield washer reservoir. If sprayed on
the windshield, coolant could make it
difficult to see through the windshield.
Note: Do not use stop leak pellets, cooling
system sealants, or non-specified additives
as they can cause damage to the engine
cooling or heating systems. Resulting
component damage may not be covered by
the vehicle Warranty.

Maintenance

Recycled Coolant
We do not recommend the use of recycled
coolant as an approved recycling process is
not yet available.
Note:Dispose of used coolant in the
appropriate manner.
Follow your community's regulations and
standards for recycling and disposing of
automotive fluids.
Severe Climates
If you drive in extremely cold climates:
• It may be necessary to increase the
coolant concentration above 50%.
• A coolant concentration of 60% provides
improved freeze point protection.
• Coolant concentrations above 60%
decrease the overheat protection
characteristics of the coolant and may
cause engine damage.If you drive in extremely hot climates:
• You can decrease the coolant
concentration to 40%.
• A coolant concentration of 40% provides
improved overheat protection.
• Coolant concentrations below 40%
decrease the overheat and corrosion
protection characteristics of the coolant
and may cause engine damage.
Vehicles driven year-round in non-extreme
climates should use prediluted coolant for
optimum cooling system and engine
protection.
Coolant Change
At specific mileage intervals, as listed in the
scheduled maintenance information, the
coolant should be changed. Add prediluted
coolant approved to the correct specification.
See Capacities and Specifications (page
460).
Fail-Safe Cooling
Fail-safe cooling allows you to temporarily
drive your vehicle before any incremental
component damage occurs. The fail-safe
distance depends on ambient temperature,
vehicle load and terrain.
How Fail-Safe Cooling Works
If the engine begins to overheat,
the coolant temperature gauge
moves toward the red zone:
A warning lamp illuminates and a
message may appear in the
information display.
If the engine reaches a preset
over-temperature condition, the engine
automatically switches to alternating cylinder
operation. Each disabled cylinder acts as an
air pump and cools the engine.
When this occurs, your vehicle still operates,
however:
• Engine power is limited.
• The air conditioning system turns off.
406
Maintenance

If you tow a trailer with your vehicle, the
engine may temporarily reach a higher
temperature during severe operating
conditions, for example ascending a long or
steep grade in high ambient temperatures.
At this time, you may notice the coolant
temperature gauge moves toward the red
zone and a message may appear in the
information display.
You may notice a reduction in vehicle speed
caused by reduced engine power in order
to manage the engine coolant temperature.
Your vehicle may enter this mode if certain
high-temperature and high-load conditions
take place. The amount of speed reduction
depends on vehicle loading, grade and
ambient temperature. If this occurs, there is
no need to stop your vehicle. You can
continue to drive.
The air conditioning may automatically turn
on and off during severe operating
conditions to protect the engine from
overheating. When the coolant temperature
decreases to the normal operating
temperature, the air conditioning turns on.If the coolant temperature gauge moves fully
into the red zone, or if the coolant
temperature warning or service engine soon
messages appear in your information display,
do the following:
1. Stop your vehicle as soon as it is safe to
do so. Fully apply the parking brake, shift
into park (P) or neutral (N).
2. Leave the engine running until the
coolant temperature gauge needle
returns to the normal position. If the
temperature does not drop after several
minutes, follow the remaining steps.
3. Switch the engine off and wait for it to
cool. Check the coolant level.
4. If the coolant level is at or below the
minimum mark, add prediluted coolant
immediately.
5. If the coolant level is normal, restart the
engine and continue.AUTOMATIC TRANSMISSION
FLUID CHECK
If required, have an authorized dealer check
and change the transmission fluid at the
correct service interval. See Scheduled
Maintenance (page 579).
The automatic transmission does not have
a transmission fluid dipstick.
Refer to your scheduled maintenance
information for scheduled intervals for fluid
checks and changes. Your transmission does
not consume fluid. However, if the
transmission slips, shifts slowly or if you
notice a sign of leaking fluid, contact an
authorized dealer.
Do not use supplemental transmission fluid
additives, treatments or cleaning agents. The
use of these materials may affect
transmission operation and result in damage
to internal transmission components.

Maintenance

BRAKE FLUID CHECK
WARNING: Do not use any fluid other
than the recommended brake fluid as this
will reduce brake efficiency. Use of
incorrect fluid could result in the loss of
vehicle control, serious personal injury or
death.
WARNING: Only use brake fluid from
a sealed container. Contamination with dirt,
water, petroleum products or other
materials may result in brake system
damage or failure. Failure to adhere to this
warning could result in the loss of vehicle
control, serious personal injury or death.
WARNING: Do not allow the fluid to
touch your skin or eyes. If this happens,
rinse the affected areas immediately with
plenty of water and contact your physician.
WARNING: The brake system could
be affected if the brake fluid level is below
the MIN mark or above the MAX mark on
the brake fluid reservoir.
E170684
1. Park your vehicle on a level surface.
2. Look at the brake fluid reservoir to see
where the brake fluid level is relative to
the MIN and the MAX marks on the
reservoir.
Note:If the brake fluid level is between the
MIN and the MAX marks on the reservoir, it
is acceptable.Note:If the brake fluid level is below the MIN
mark or above the MAX mark, have your
vehicle checked as soon as possible.
Note:To avoid fluid contamination, the
reservoir cap must remain in place and fully
tight, unless you are adding fluid.
Only use fluid that meets our specifications.
See Capacities and Specifications (page
460).
Brake Fluid Service Interval
Brake fluid absorbs water over time which
degrades the effectiveness of the brake fluid.
Change the brake fluid at the specified
intervals to prevent degraded braking
performance.
For detailed interval information, see
Scheduled Maintenance in your Owner's
Manual or your local maintenance guide.
POWER STEERING FLUID CHECK
Your vehicle is equipped with an electric
power steering (EPS) system. There is no
fluid reservoir to check or fill.
409
Maintenance

Tire Rotation
WARNING: If the tire label shows
different tire pressures for the front
and rear tires and the vehicle has a
tire pressure monitoring system, then
you need to update the settings for
the system sensors. Always perform
the system reset procedure after tire
rotation. If you do not reset the system,
it may not provide a low tire pressure
warning when necessary.
Note:If your tires show uneven wear,
ask an authorized dealer to check for
and correct any wheel misalignment,
tire imbalance or mechanical problem
involved before tire rotation.Note:Your vehicle may be equipped
with a dissimilar spare wheel and tire
assembly. A dissimilar spare wheel and
tire assembly is defined as a spare
wheel and tire assembly that is different
in brand, size or appearance from the
road tires and wheels. If you have a
dissimilar spare wheel and tire
assembly, it is intended for temporary
use only and should not be used in a
tire rotation.
Note:After having your tires rotated,
inflation pressure must be checked and
adjusted to the vehicle requirements.
Rotating your tires at the recommended
interval will help your tires wear more
evenly, providing better tire performance
and longer tire life. Sometimes irregular
tire wear can be corrected by rotating
the tires. See Scheduled Maintenance
(page 579).

USING SUMMER TIRES
Summer tires provide superior performance
on wet and dry roads. Summer tires do not
have the Mud and Snow (M+S or M/S) tire
traction rating on the tire side wall. Since
summer tires do not have the same traction
performance as All-season or Snow tires, we
do not recommend using summer tires when
temperatures drop to approximately 45°F
(7°C) or below (depending on tire wear and
environmental conditions) or in snow and ice

GENERAL MAINTENANCE
INFORMATION
Why Maintain Your Vehicle?
Carefully following the maintenance
schedule helps protect against major repair
expenses resulting from neglect or
inadequate maintenance and may help to
increase the value of your vehicle when you
sell or trade it. Keep all receipts for
completed maintenance with your vehicle.
We have established regular maintenance
intervals for your vehicle based upon
rigorous testing. It is important that you have
your vehicle serviced at the proper times.
These intervals serve two purposes: one is
to maintain the reliability of your vehicle and
the second is to keep your cost of owning
your vehicle down.
It is your responsibility to have all scheduled
maintenance performed and to make sure
that the materials used meet the
specifications identified in this owner's
manual. See Capacities and Specifications
(page 460).Failure to perform scheduled maintenance
invalidates warranty coverage on parts
affected by the lack of maintenance.
Why Maintain Your Vehicle at Your
Dealership?
Factory-Trained Technicians
Service technicians participate in extensive
factory-sponsored certification training to
help them become experts on the operation
of your vehicle. Ask your dealership about
the training and certification their technicians
have received.
Our Genuine Replacement Parts
Dealerships stock our genuine manufactured
or our authorized re-manufactured
replacement parts. These parts meet or
exceed our specifications. Parts installed at
your dealership carry a nationwide 24-month
or unlimited mile (kilometer) parts and labor
limited warranty.
If you do not use our authorized parts they
may not meet our specifications and
depending on the part, it could affect
emissions compliance.Convenience
Many dealerships have extended evening
and Saturday hours to make your service
visit more convenient and they offer one stop
shopping. They can perform any services
that are required on your vehicle, from
general maintenance to collision repairs.
Note:Not all dealers have extended hours
or body shops. Please contact your dealer
for details.
Protecting Your Investment
Maintenance is an investment that pays
dividends in the form of improved reliability,
durability and resale value. To maintain the
proper performance of your vehicle and its
emission control systems, make sure you
have scheduled maintenance performed at
the designated intervals.
Your vehicle has an Intelligent Oil-Life
Monitor system; a message appears in the
