DRIVING AND OPERATING 199
R (Reverse) :To back up, press down
the clutch pedal, completely stop the
vehicle, and shift into R (Reverse). On
ATS models, apply additional pressure
to get the lever past 1 (First) and
2 (Second) into R (Reverse). Let up on
the clutch pedal slowly while pressing
the accelerator pedal.
{Warning
If you skip a gear when
downshifting, you could lose
control of the vehicle. You could
injure yourself or others. Do not
shift down more than one gear at a
time when downshifting.
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
On ATS-V vehicles equipped with a
manual transmission, 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 vehicle
modes and is only active when the
engine speed is greater than 2500 rpm.
Active Rev Match
ATS-V 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 either of the
paddles on the steering wheel. The
system must be activated with each
new ignition cycle.
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.
. When ARM is deactivated, the
gear number is white.
