recirculation mode and allow outside air into the vehicle. NOTE:
In cold weather, use of recirculation mode may lead
to excessive window fogging. The recirculation feature
may be unavailable (button on the touchscreen greyed out)
if conditions exist that could create fogging on the inside of
the windshield.

70 GETTING TO KNOW YOUR VEHICLE

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.
CAUTION!
•When installing the power distribution center cover,
it is important to ensure the cover is properly posi-
tioned 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.
• When replacing a blown fuse, it is important to use
only a fuse having the correct amperage rating. The
use of a fuse with a rating other than indicated 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.

Preparations For Jump Start
The battery is stored under an access cover in the trunk.
Remote battery posts are located on the right side of the
engine compartment for jump starting.
WARNING!
•Take care to avoid the radiator cooling fan whenever
the hood is raised. It can start anytime the ignition
switch is ON. You can be injured by moving fan
blades.
• Remove any metal jewelry such as rings, watch
bands and bracelets that could make an inadvertent
electrical contact. You could be seriously injured.
• Batteries contain sulfuric acid that can burn your
skin or eyes and generate hydrogen gas which is
flammable and explosive. Keep open flames or
sparks away from the battery.
1. Apply the parking brake, shift into PARK (automatic transmission) or FIRST GEAR (manual transmission)
and cycle the ignition to OFF.
2. Turn off the heater, radio, and all unnecessary electrical accessories.

to the radiator and aids in removing heat from the
engine cooling system.
WARNING!
You or others can be badly burned by hot engine
coolant (antifreeze) or steam from your radiator. If you
see or hear steam coming from under the hood, do not
open the hood until the radiator has had time to cool.
Never try to open a cooling system pressure cap when
the radiator or coolant bottle is hot.
CAUTION!
Driving with a hot cooling system could damage your
vehicle. If the temperature gauge reads HOT (H), pull
over and stop the vehicle. Idle the vehicle with the air
conditioner turned off until the pointer drops back
into the normal range. If the pointer remains on HOT
(H), and you hear continuous chimes, turn the engine
off immediately and call for service.
MANUAL PARK RELEASE — 8 SPEED
TRANSMISSION
WARNING!
Always secure your vehicle by fully applying the
parking brake before activating the Manual Park Re-
lease. In addition, you should be seated in the driver’s
seat with your foot firmly on the brake pedal when
activating the Manual Park Release. Activating the
Manual Park Release will allow your vehicle to roll
away if it is not secured by the parking brake, or by
proper connection to a tow vehicle. Activating the
Manual Park Release on an unsecured vehicle could
lead to serious injury or death for those in or around
the vehicle.
In order to move the vehicle in cases where the transmis-
sion will not shift out of PARK (such as a dead battery), a
Manual Park Release is available.

Adding Washer Fluid
The windshield washer fluid reservoir is located in the
front of the engine compartment. Be sure to check the fluid
level at regular intervals. Fill the reservoir with windshield
washer solvent (not radiator antifreeze) and operate the
system for a few seconds to flush out the residual water.
When refilling the washer fluid reservoir, apply some
washer fluid to a cloth or towel and wipe the wiper blades
clean. This will help blade performance.
To prevent freeze-up of your windshield washer system in
cold weather, select a solution or mixture that meets or
exceeds the temperature range of your climate. This rating
information can be found on most washer fluid containers.
The fluid reservoir will hold nearly 1 gallon (4 liters) of
washer fluid when the message “Low Washer Fluid”
appears in the instrument cluster.
WARNING!
Commercially available windshield washer solvents
are flammable. They could ignite and burn you. Care
must be exercised when filling or working around the
washer solution.
Maintenance-Free Battery
Your vehicle is equipped with a maintenance-free battery.
You will never have to add water, nor is periodic mainte-
nance required.
NOTE:The battery is stored under an access cover in the
trunk. Remote battery terminals are located in the engine
compartment for jump starting. Refer to “Jump Starting
Procedures” in “In Case Of Emergency” for further infor-
mation.

WARNING!(Continued)
•When working near the radiator cooling fan, discon-
nect the fan motor lead. The fan is temperature
controlled and can start at any time regardless of
ignition mode. You could be injured by the moving
fan blades.
• You can be badly injured working on or around a
motor vehicle. Only do service work for which you
have the knowledge and the proper equipment. If
you have any doubt about your ability to perform a
service job, take your vehicle to a competent me-
chanic.
When inspecting accessory drive belts, small cracks that
run across ribbed surface of belt from rib to rib, are
considered normal. These are not a reason to replace belt.
However, cracks running along a rib (not across) are not
normal. Any belt with cracks running along a rib must be
replaced. Also have the belt replaced if it has excessive
wear, frayed cords or severe glazing. Conditions that would require replacement:
•
Rib chunking (one or more ribs has separated from belt
body)
• Rib or belt wear
• Longitudinal belt cracking (cracks between two ribs)
• Belt slips
• “Groove jumping (belt does not maintain correct posi-
tion on pulley)
• Belt broken (note: identify and correct problem before
new belt is installed)
