The cap should be inspected and cleaned if there is any
accumulation of foreign material on the sealing surfaces.
Disposal Of Used Coolant
Used ethylene glycol-based coolant (antifreeze) is a
regulated substance requiring proper disposal. Check with
your local authorities to determine the disposal rules for
your community. To prevent ingestion by animals or
children, do not store ethylene glycol-based coolant in
open containers or allow it to remain in puddles on the
ground. If ingested by a child or pet, seek emergency
assistance immediately. Clean up any ground spills
immediately.
Coolant Level
The coolant expansion bottle provides a quick visual
method for determining that the coolant level is adequate.
With the engine off and cold, the level of the coolant
(antifreeze) in the bottle should be between the “MAX”
and “MIN” lines marked on the bottle. As long as the engine operating temperature is
satisfactory, the coolant bottle need only be checked once
a month.
When additional coolant is needed to maintain the proper
level, it should be added to the coolant bottle. Do not
overfill.
See an authorized dealer for service.
Cooling System Notes
NOTE:When the vehicle is stopped after a few miles/kilometers
of operation, you may observe vapor coming from the front
of the engine compartment. This is normally a result of
moisture from rain, snow, or high humidity accumulating
on the radiator and being vaporized when the thermostat
opens, allowing hot engine coolant (antifreeze) to enter
the radiator.
If an examination of your engine compartment shows no
evidence of radiator or hose leaks, the vehicle may be
safely driven. The vapor will soon dissipate.

Do not overfill the coolant expansion bottle.
 Check the coolant freeze point in the radiator and in
the coolant expansion bottle. If engine coolant needs
to be added, the contents of the coolant expansion
bottle must also be protected against freezing.
 If frequent engine coolant additions are required, the
cooling system should be pressure tested for leaks.
 Maintain engine coolant concentration at a minimum
of 50% OAT coolant (conforming to MS.90032) and
distilled water for proper corrosion protection of your
engine which contains aluminum components. 
Make sure that the coolant expansion bottle overflow
hoses are not kinked or obstructed.
 Keep the front of the radiator clean. If your vehicle is
equipped with air conditioning, keep the front of the
condenser clean.
 Do not change the thermostat for Summer or Winter
operation. If replacement is ever necessary, install
ONLY the correct type thermostat. Other designs may
result in unsatisfactory engine cooling performance,
poor gas mileage, and increased emissions.BRAKE SYSTEM
In order to ensure brake system performance, all brake
system components should be inspected periodically. For
the proper maintenance intervals
Úpage 260.
WARNING!
Do not open a hot engine cooling system. Never add
engine coolant (antifreeze) when the engine is over -
heated. Do not loosen or remove the cap to cool an
overheated engine. Heat causes pressure to build-up
in the cooling system. To prevent scalding or injury,
do not remove the pressure cap while the system is
hot or under pressure.
 Do not use a pressure cap other than the one speci -
fied for your vehicle. Personal injury or engine
damage may result.
WARNING!
Riding the brakes can lead to brake failure and possibly
a collision. Driving with your foot resting or riding on the
brake pedal can result in abnormally high brake
temperatures, excessive lining wear, and possible brake
damage. You would not have your full braking capacity
in an emergency.

Brake Master Cylinder
The fluid in the master cylinder should be checked when
performing under hood services or immediately if the
Brake Warning Light is illuminated.
Be sure to clean the top of the master cylinder area before
removing the cap. If necessary, add fluid to bring the fluid
level up to the requirements described on the brake fluid
reservoir. With disc brakes, fluid level can be expected to
fall as the brake pads wear. Brake fluid level should be
checked when pads are replaced. However, low fluid level
may be caused by a leak and a checkup may be needed.
Use only manufacturer recommended brake fluid
Úpage 307.AUTOMATIC TRANSMISSION
Special Additives
The manufacturer strongly recommends against using any
special additives in the transmission. Automatic
Transmission Fluid (ATF) is an engineered product and its
performance may be impaired by supplemental additives.
Therefore, do not add any fluid additives to the
transmission. Avoid using transmission sealers as they
may adversely affect seals.
Fluid Level Check
The fluid level is preset at the factory and does not require
adjustment under normal operating conditions. Routine
fluid level checks are not required; therefore the
transmission has no dipstick. An authorized dealer can
check your transmission fluid level using special service
tools. If you notice fluid leakage or transmission
malfunction, visit an authorized dealer immediately to
have the transmission fluid level checked. Operating the
vehicle with an improper fluid level can cause severe
transmission damage.
Fluid And Filter Changes
Under normal operating conditions, the fluid installed at
the factory will provide satisfactory lubrication for the life
of the vehicle.
Routine fluid and filter changes are not required. However,
change the fluid and filter if the fluid becomes
contaminated (with water, etc.), or if the transmission is
disassembled for any reason.
Selection Of Lubricant
It is important to use the proper transmission fluid to
ensure optimum transmission performance and life. Use
only the manufacturer specified transmission fluid
Úpage 307. It is important to maintain the transmission
fluid at the correct level using the recommended fluid.
WARNING!
 Use only manufacturer recommended brake fluid Úpage 307. Using the wrong type of brake fluid can
severely damage your brake system and/or impair its
performance. The proper type of brake fluid for your
vehicle is also identified on the original factory
installed hydraulic master cylinder reservoir.
 To avoid contamination from foreign matter or mois -
ture, use only new brake fluid or fluid that has been
in a tightly closed container. Keep the master
cylinder reservoir cap secured at all times. Brake
fluid in an open container absorbs moisture from the
air resulting in a lower boiling point. This may cause
it to boil unexpectedly during hard or prolonged
braking, resulting in sudden brake failure. This could
result in a collision.
 Overfilling the brake fluid reservoir can result in
spilling brake fluid on hot engine parts, causing the
brake fluid to catch fire. Brake fluid can also damage
painted and vinyl surfaces, care should be taken to
avoid its contact with these surfaces.
 Do not allow petroleum-based fluid to contaminate
the brake fluid. Brake seal components could be
damaged, causing partial or complete brake failure.
This could result in a collision.
CAUTION!
Do not use chemical flushes in your transmission as the
chemicals can damage your transmission components.
Such damage is not covered by the New Vehicle Limited
Warranty.
WARNING!
CAUTION!
If a transmission fluid leak occurs, visit an authorized
dealer immediately. Severe transmission damage may
occur. An authorized dealer has the proper tools to
adjust the fluid level accurately.

NOTE:No chemical flushes should be used in any transmission;
only the approved lubricant should be used.
FUSES
General Information
The fuses protect electrical systems against excessive
current.
When a device does not work, you must check the fuse
element inside the blade fuse for a break/melt.
Also, please be aware that using power outlets for
extended periods of time with the engine off may result in
vehicle battery discharge.

Blade Fuses

Underhood Fuses
The Power Distribution Center (PDC) is located in the
engine compartment near the battery. This center
contains cartridge fuses, mini-fuses, micro-fuses, circuit
breakers and relays. A label that identifies each
component is printed on the inside of the cover.
Before any procedure is done on the PDC, make sure
engine is turned off.
Remove the cover by unlatching the two locks located at
each side of the PDC cover, avoid using screwdrivers or
any other tool to remove the cover, since they may apply
excessive force and result in a broken/damaged part.
After service is done, secure the cover with its two locks.
NOTE:The function and amperage of the following fuses are
different, depending on vehicle trim level and content.
CAUTION!
Using a transmission fluid other than the manufacturer
recommended fluid may cause deterioration in
transmission shift quality and/or torque converter
shudder
Úpage 307.
WARNING!
When replacing a blown fuse, always use an appro -
priate replacement fuse with the same amp rating as
the original fuse. Never replace a fuse with another
fuse of higher amp rating. Never replace a blown
fuse with metal wires or any other material. Do not
place a fuse inside a circuit breaker cavity or vice
versa. Failure to use proper fuses may result in
serious personal injury, fire and/or property damage.
 Before replacing a fuse, make sure that the ignition
is off and that all the other services are switched off
and/or disengaged.
 If the replaced fuse blows again, contact an autho -
rized dealer.
 If a general protection fuse for safety systems (air
bag system, braking system), power unit systems
(engine system, transmission system) or steering
system blows, contact an authorized dealer.

WARNING!
CAUTION!
When installing the power distribution center cover, it is
important to ensure the cover is properly positioned
and fully latched. Failure to do so may allow water to get
into the power distribution center and possibly result in
an electrical system failure.
