2017 CHRYSLER PACIFICA HYBRID gas type

On the other hand, depending on the type and location of
impact, front air bags may deploy in crashes with little
vehicle front-end damage but that produce a severe initial
deceleration.
Because air bag sensors measure vehicle deceleration over
time, vehicle speed and damage by themselves are not
good indicators of whether or not an air bag should have
deployed.
Seat belts are necessary for your protection in all collisions,
and also are needed to help keep you in position, away
from an inflating air bag.
When the ORC detects a collision requiring the front air
bags, it signals the inflator units. A large quantity of
non-toxic gas is generated to inflate the front air bags.
The steering wheel hub trim cover and the upper right side
of the instrument panel separate and fold out of the way as
the air bags inflate to their full size. The front air bags fully
inflate in less time than it takes to blink your eyes. The
front air bags then quickly deflate while helping to restrain
the driver and front passenger.Occupant Classification System (OCS) — Front
Passenger Seat
The OCS is part of a Federally regulated safety system for
this vehicle. It is designed to provide Passenger Advanced
Front Air Bag output appropriate to the occupant’s seated
weight, as determined by the OCS.
The Occupant Classification System (OCS) consists of the
following:
•Occupant Restraint Controller (ORC)
• Occupant Classification Module (OCM) and Sensor lo-
cated in the front passenger seat
• Air Bag Warning Light
Occupant Classification Module (OCM) And Sensor
The Occupant Classification Module (OCM) is located
underneath the front passenger seat. The Sensor is located
beneath the passenger seat cushion foam. Any weight on
the seat will be sensed by the Sensor. The OCM uses input
from the Sensor to determine the front passenger ’s most
probable classification. The OCM communicates this infor-
mation to the ORC. The ORC may reduce the inflation rate
of the Passenger Advanced Front Air Bag deployment
based on occupant classification. In order for the OCS to

•If a “fast charger” is used while the battery is in the
vehicle, disconnect both vehicle battery cables before
connecting the charger to the battery. Do not use a
“fast charger” to provide starting voltage.
DEALER SERVICE
Your authorized dealer has the qualified service personnel,
special tools, and equipment to perform all service opera-
tions in an expert manner. Service Manuals are available
which include detailed service information for your ve-
hicle. Refer to these Service Manuals before attempting any
procedure yourself.
NOTE: Intentional tampering with emissions control sys-
tems may void your warranty and could result in civil
penalties being assessed against you.
WARNING!
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 mechanic.
Engine Oil
Change Engine Oil
The oil change indicator system will remind you that it is
time to take your vehicle in for scheduled maintenance.
Even if the vehicle is driven, such that it operates primarily
in electric mode, the engine oil still requires changing. An
engine oil change maintenance reminder message will be
provided based on vehicle use and time since last oil
change. Refer to the “Scheduled Servicing” in this section
for further information.
NOTE: Under no circumstances should oil change inter-
vals exceed 10,000 miles (16,000 km), twelve months or 350
hours of engine run time, whichever comes first. The 350
hours of engine run or idle time is generally only a concern
for fleet customers.
Gasoline Engine Oil Selection
For best performance and maximum protection under all
types of operating conditions, the manufacturer only rec-
ommends engine oils that are API Certified and meet the
requirements of FCA Material Standard MS-6395.

Points To Remember
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 (anti-
freeze) 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 (antifreeze)
needs to be added, the contents of the coolant expansion
bottle must also be protected against freezing.
• If frequent engine coolant (antifreeze) additions are
required, the cooling system should be pressure tested
for leaks.
• Maintain coolant (antifreeze) concentration at a mini-
mum of 50% OAT coolant (conforming to MS.90032) and
deionized, or distilled water. •
Use only high purity water such as deionized, or dis-
tilled water when mixing the water/engine coolant
(antifreeze) solution. The use of lower quality water will
reduce the amount of corrosion protection in the cooling
system.
• 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 coolant (antifreeze) performance,
poor gas mileage, and increased emissions.
• The coolant freeze point in the battery and power
electronics loop should be checked by a dealer as a
special tool is required to remove the cap from those
expansion bottles.
• Electric/Battery coolant system must be serviced by
your authorized dealer. If the coolant level is below what
is specified on the reservoir, contact your authorized
dealer for service. These systems require the use of high
