1 Latch 2 Strap 3 Locking cylinder 4 Operating lever 5 Upper cable 6 Cable joint 7 Lower cable 8 Cable bracket 9 Park interlock lever If a vehicle requires recovery/transportation, the emergency park release mechanism is used to manually disengage the park
lock and engage the transmission in neutral.

The emergency park release mechanism consists of an operating lever that is connected to a park interlock lever on the
transmission by an upper and lower cable assembly.

The operating lever is installed in the floor console, under the trim panel between the drinks holder and the cubby box. The
park interlock lever is attached to the transmission selector shaft.

One end of the operating lever is attached to a base by a hinge pin. A locking cylinder is installed in the other end of the
operating lever, to secure the operating lever to the base. The operating lever is raised by pulling on a strap.
When operated, the emergency park release mechanism turns the transmission selector shaft.
To disengage the park lock:
Open the cubby box lid and the drinks holder lid.
Remove the trim panel from between the drinks holder and the cubby box.
Rotate the locking mechanism of the emergency park release lever 90 degrees counterclockwise.
Apply the footbrake, pull the operating lever upwards and ensure it locks in the vertical position.

Raising the operating lever causes the emergency park release cable to rotate the park interlock lever on the transmission,
which disengages the parking pawl and engages neutral. This allows the vehicle to freewheel.
To re-engage the park lock:

Hold the strap on the operating lever, release the latch and lower the operating lever to the horizontal position.
Lock the operating lever by turning the locking mechanism 90 degrees clockwise.
Install the trim panel.
Close the cubby box lid and the drinks holder lid. www.JagDocs.com

Description and Operation



CATALYTIC CONVERTERS System Operation

In the catalytic converters, the exhaust gases are passed through honeycombed ceramic elements coated with a special
surface treatment called 'washcoat'. The washcoat increases the surface area of the ceramic elements by a factor of
approximately 7000. On top of the washcoat is a coating containing palladium and rhodium, which are the active constituents
for converting harmful emissions into inert by-products. The palladium and rhodium add oxygen to the carbon monoxide and
the hydrocarbons in the exhaust gases, to convert them into carbon dioxide and water respectively.

SEMI-ACTIVE MUFFLER VALVE (5.0L SUPERCHARGER VEHICLES ONLY)

The semi-active muffler valve is operated by the pressure in the exhaust system. At low engine speeds the valve head is
closed or partially closed to provide a more refined noise quality. At higher engine speeds the increased pressure within the
exhaust system opens the valve head to provide a more sporting noise. This is achieved by the valve, which once open, allows
the exhaust gasses to by-pass the baffle tubes and plates in the rear silencer.

Component Description
FRONT SECTION - 4.2L NATURALLY ASPIRATED (NAS ONLY) - From 2010MY

The front section comprises two separate pipes, each incorporating a catalytic converter. Each catalytic converter has a welded
inlet pipe with a flange. The inlet pipe is flared into a cone which mates with the exhaust manifold. The flange has two holes
which locate on studs in the exhaust manifold and is secured with flanged nuts. Each catalytic converter is fitted with a pre
and post catalyst HO2S (heated oxygen sensor).

Each catalytic converter has a curved outlet pipe which mates with the respective inlet pipe for the applicable resonator on the
center section. The joint on each pipe is secured with a clamp.

FRONT SECTION - 5.0L NATURALLY ASPIRATED AND SUPERCHARGER - From 2010MY

The front section is common to both the naturally aspirated and supercharger vehicles. The front section comprises two
separate pipes each incorporating a catalytic converter. Each catalytic converter has a welded pipe with a flange, which is
flared into a cone which mates with the exhaust manifold. Each flange has two holes which locate on studs in the exhaust
manifold and are secured with nuts. Each catalytic converter is fitted with a mid catalyst HO2S. The mid catalyst HO2S is located in the catalytic converter.


NOTE: The pre catalyst HO2S is located in the exhaust manifold.
On vehicles from 2013MY, a post catalyst HO2S is located in the curved pipe from each catalytic converter.
A curved pipe from each catalytic converter locates into the resonator inlet pipes of the center section. The LH (left-hand) pipe
is fitted with a mass damper which absorbs resonance from the system.

REAR SECTION - 4.2L NATURALLY ASPIRATED (NAS ONLY) - From 2010MY

The 2 inlet pipes each connect into a separate resonator silencer. Each resonator silencer is cylindrical in shape and houses 2
perforated tubes separated by 2 baffle plates. Exhaust gasses exit each resonator silencer via an outlet pipe. The 2 outlet
pipes are joined together behind the resonators with a cross over pipe. Each pipe also has a welded hanger bracket which
allow the rear section to be supported on mounting rubbers. A further bracket is welded to each pipe which braces the 2 pipes
together.

The 2 rear silencers each have a welded inlet pipe which mate with the outlet pipes from the resonator silencers and are each
secured with a clamp. The inlet pipes each have a welded hanger bracket which support each rear silencer at the rear of the
vehicle on mounting rubbers. The fabricated rear silencers have 2 perforated tubes which are supported on 2 perforated baffle
plates. The exhaust gasses are expelled from the rear silencer via a single outlet pipe. The outlet pipe from each silencer has
a welded hanger bar which support the rear silencer on mounting rubbers. The outlet pipe is fitted with a welded outlet which
is covered with a polished stainless steel finisher which is part welded to the silencer.

REAR SECTION - 5.0L NATURALLY ASPIRATED - From 2010MY

The 2 pipes from the front section each connect into 2 short pipes on the center resonator box and are secured with clamps.
Two pipes from the resonator box split the system into 2 sections which each connect into another resonator. Each resonator
silencer houses perforated tubes separated by baffle plates. Exhaust gasses exit each resonator silencer via an outlet pipe.
The 2 outlet pipes are joined together behind the resonators with a cross over pipe. Each pipe also has a welded hanger
bracket which allow the rear section to be supported on mounting rubbers. A further bracket is welded to each pipe which
braces the 2 pipes together.
The 2 rear silencers each have a welded inlet pipe which mate with the outlet pipes from the cylindrical resonator silencers and
