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 drivermodes 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.

Driving and Operating 291
Both systems come on
automatically when the vehicle
is started and begins to move.
The systems may be heard or
felt while they are operating
or while performing diagnostic
checks. This is normal and
does not mean there is a
problem with the vehicle.
It is recommended to leave
both systems on for normal
driving conditions, but It may
be necessary to turn TCS off
if the vehicle gets stuck in
sand, mud, ice, or snow. See If
the Vehicle Is Stuck0255 and
“Turning the Systems Off and
On” later in this section.
The indicator light for both
systems is in the instrument
cluster. This light will:
.Flash when TCS is limiting
wheel spin.
.Flash when StabiliTrak/ESC
is activated.
.Turn on and stay on when
either system is not working.
If either system fails to turn on
or to activate, a message may
display in the Driver
Information Center (DIC), and
dcomes on and stays on to
indicate that the system is
inactive and is not assisting
the driver in maintaining
control. The vehicle is safe to
drive, but driving should be
adjusted accordingly.
If
dcomes on and stays on:
1. Stop the vehicle.
2. Turn the engine off and wait 15 seconds.
3. Start the engine.
Drive the vehicle. if
dcomes
on and stays on, the vehicle
may need more time to
diagnose the problem. If the
condition persists, see your
dealer.

Adaptive Cruise
Control (Advanced)
If equipped, Adaptive Cruise
Control (ACC) allows the
cruise control set speed and
following gap to be selected.
Read this entire section
before using this system. The
following gap is the following
time between your vehicle and
a vehicle detected directly
ahead in your path, moving in
the same direction. If no
vehicle is detected in your
path, ACC works like regular
cruise control. ACC uses
camera and radar sensors.
See Radio Frequency
Statement 0494.
If a vehicle is detected in your
path, ACC can speed up the
vehicle or apply limited,
moderate braking to maintain
