Cooling System Pressure Cap
The cap must be fully tightened to prevent loss of
engine coolant (antifreeze), and to ensure that
engine coolant will return to the radiator from the
coolant expansion bottle/recovery tank
(if equipped).
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:
clean up any ground spills immediately. If ingested,
seek emergency assistance immediately.
Coolant Level
The coolant bottle provides a quick visual method
for determining that the engine coolant
(antifreeze) level is adequate. With the engine off
and cold, the level of the engine coolant in the
bottle should be between the ranges indicated on
the bottle.
The radiator normally remains completely full, so
there is no need to remove the radiator cap unless
checking for engine coolant freeze point or
replacing engine coolant. Advise your service
attendant of this. As long as the engine operating
temperature is satisfactory, the coolant bottle
need only be checked once a month.
When additional engine coolant is needed to
maintain the proper level, it should be added to the
coolant bottle. Do not overfill.
Cooling System Notes
NOTE:When the vehicle is stopped after a few miles/kilo -
meters 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 corro -
sion protection of your engine which contains
aluminum components.
WARNING!
Do not open hot engine cooling system. Never
add engine coolant (antifreeze) when the
engine is overheated. 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
specified for your vehicle. Personal injury or
engine damage may result.8

(Continued)
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 neces-
sary, 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 Ú page 255.
Fluid Level Check — Brake Master Cylinder
Check the fluid level in the master cylinder
immediately if the Brake System Warning Light
indicates system failure.
Check the fluid level in the master cylinder when
performing underhood services.
Clean the top of the master cylinder area before
removing the cap. Add fluid to bring the level up to
the top of the “FULL” mark on the side of the
master cylinder reservoir.
Overfilling of fluid is not recommended because it
may cause leaking in the system.
Add enough fluid to bring the 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. However,
low fluid level may be caused by a leak and a
checkup may be needed.
Use only brake fluid that has been recommended
by the manufacturer, and has been kept in a tightly
closed container to avoid contamination from
foreign matter or moisture Ú page 316.
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.
WARNING!
Use only manufacturer's recommended brake
fluid Úpage 316. 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
moisture, 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 a 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.

CLUTCH HYDRAULIC SYSTEM — MANUAL
T
RANSMISSION (IF EQUIPPED)
The clutch hydraulic system is fed by a segregated
volume of fluid within the brake system master
cylinder reservoir. In the event of leakage or wear,
use only the manufacturer's recommended brake
fluid Ú page 316.
MANUAL TRANSMISSION — IF EQUIPPED
Fluid Level Check
Check the fluid level by removing the fill plug on the
left side of the transmission. The fluid level should
be 1/4 inch (6.4mm) below the bottom of the fill
hole. Add fluid, if necessary, to maintain the proper
level Ú page 316.
Change Transmission Fluid
If contaminated with water, change the fluid
immediately. See an authorized dealer for service.
For the proper maintenance intervals Úpage 255.
AUTOMATIC TRANSMISSION —
I
F EQUIPPED
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.
Do not allow petroleum based fluid to contam -
inate the brake fluid. Brake seal components
could be damaged, causing partial or
complete brake failure. This could result in a
collision.
WARNING!CAUTION!
Using a transmission fluid other than the
manufacturer's recommended fluid may cause
deterioration in transmission shift quality and/or
damage to the transmission Ú page 316.
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.
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.

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's specified
transmission fluid Úpage 316. It is important to
maintain the transmission fluid at the correct level
using the recommended fluid.
NOTE:No chemical flushes should be used in any trans -
mission; only the approved lubricant should be
used.
ALL-WHEEL DRIVE (AWD) —
I
F EQUIPPED
The All-Wheel Drive system consists of a transfer
case and front differential. The exterior surface of
these components should be inspected for
evidence of fluid leaks. Confirmed leaks should be
repaired as soon as possible.
The transfer case fluid fill/inspection plug is
located in the middle of the rear housing. To
inspect the transfer case fluid level, remove the
fill/inspection plug. The fluid level should be even
with the bottom of the hole. Use this plug to add
fluid as required.
The front differential fill plug is located on the outer
cover near the half shaft attachment. To inspect
the differential fluid level, remove the fill plug. The
fluid level should be even with or slightly below the
bottom of the hole.
Fluid Changes
For the proper maintenance intervals Úpage 254.
REAR AXLE
Fluid Level Check
Checking the fluid level while the vehicle is on level
ground and has been stationary for 15 minutes will
improve the accuracy of the fluid level reading.
Check the fluid level by removing the fill plug on the
axle. The fluid level should be 1-2.5 mm below the
fill plug. Add fluid, if necessary, to maintain the
proper level Ú page 316.
Change Axle Fluid
For the proper maintenance intervals Úpage 254.
CAUTION!
Using a transmission fluid other than the
manufacturer’s recommended fluid may cause
deterioration in transmission shift quality and/or

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 Front Power Distribution Center is located in
the engine compartment. This module contains
fuses and relays. Fuse cavity location and
descriptions are printed on the inside of the power
distribution center cover.
WARNING!
When replacing a blown fuse, always use an
appropriate replacement fuse with the same
amp rating as the original fuse. Never replace
a fuse with another fuse of higher amp rating.
The use of a fuse with a rating other than indi -
cated may result in a dangerous electrical
system overload. If a properly rated fuse
continues to blow, it indicates a problem in the
circuit that must be corrected. Never replace a
blown fuse with metal wires or any other mate -
rial. 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
authorized 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.

element
3 — Blade fuse with a bad/not functional fuse
element (blown fuse)
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.
