Driving and Operating
285
Caution
Do not rest your hand on
the shift lever while driving.
The pressure could cause
premature wear in the
transmission. The repairs
would not be covered by the
vehicle warranty.
Caution
When downshifting, if more
than one gear is skipped,
or the engine is racing when
the clutch pedal is released,
the engine, clutch, driveshaft
or transmission could be
damaged.
No Lift-Shift
The vehicle can be shifted up
a gear when the accelerator
pedal is pressed to the floor
without being released. This
allows for less power
interruption and will improve
acceleration times. This
feature is available in all driver
modes and is only active when
the engine speed is
greater than:
Gears 1, 2 and 3 - above
3000 rpm
Gears 4 and 5 - above
2000 rpm
Active Rev Match
Vehicles equipped with a
manual transmission have
Active Rev Match (ARM). ARM
aids in smoother shifting by
matching the engine speed to
the next selected gear. By
monitoring shift lever and
clutch operation, ARM adjusts
engine speed to match a
calibrated value based on gear
selection. On upshifts and
downshifts, engine speed will
be increased and decreased to
match vehicle road speed and
transmission gear position.
ARM is maintained while the
clutch pedal is pressed, but
will deactivate if the shift lever
is left in the Neutral position.
The system is activated and
deactivated by pressing the
ARM switch on the center
console. The system must be
activated with each new
ignition cycle. If ARM is
deactivated, the system will
still perform rev matching for
upshifts.
A gear indicator in the
instrument cluster displays the
current gear selected. ARM is
also shown in the
Performance View of the HUD:
.
When ARM is activated, the
gear number is amber.
