Exhaust (09.00)
Silencer Assembly (09.01)
Variable Flow Silencer Assembly
The rear silencer assembly has a variable fl ow path controlled by two bypass valves.
The system is intended to enhance top end performance in mo tor sport applications and will not operate in most normal
driving conditions.
By directing exhaust gasses through a modified path at high vehicle speeds, exhaust back pressure is reduced and top end
performance is enhanced.
As engine speed increase from idle, the bypass valve is open until the engine speed is 1500 rpm.
From 1500 rpm to 3000 rpm, the valve is closed
Above 3000 rpm the bypass valves state is load dependent (fully open at higher loads).

Steering (11.00)
Steering Column (11.04)
Description
The steering column has reach and tilt functions. These let
the driver manually set the position of the steering column.
by using the reach / tilt lever that is on the underside of the
steering column.This is indepe ndent of the ignition switch
position .
The steering intermediate shaft has two parts. The lower
shaft is attached to both th e steering gear and the upper
shaft.
The Electronic Steering Column Lock (ESCL) is attached to
the upper casting of the steering column and has a locking
pin. The steering column is electrically unlocked when the
ignition key is installed and operated to position 2. The lock
engages when the ignition switch is removed and the
steering wheel is turned to the centre position.
