DRIVING AND OPERATING 251
Caution
Shifting the vehicle initially into
any gear other than 1 (First) or
R (Reverse) can damage the clutch.
Shift the manual transmission in
the proper sequence, and time the
gear shifting with the accelerator to
avoid revving the engine and
damaging the clutch.
Caution
The message MANUAL
TRANSMISSION—RELEASE
CLUTCH PEDAL displays and a
chime sounds if the manual
transmission clutch pedal is
partially applied for an extended
period of time while the vehicle is
being driven. Driving with the
clutch pedal applied can reduce the
life of the clutch and/or damage it.
Fully release the clutch pedal after
each gear change.
Caution
The message REDUCED
PERFORMANCE —REDUCE
CLUTCH USE displays and engine
torque is momentarily limited if
excessive manual transmission
clutch slip is detected while the
clutch pedal is fully released. This
could be caused by a hot clutch.
Apply less pressure on the
accelerator pedal when accelerating
from a stop. Also, fully release the
accelerator pedal during gear
changes. This will allow the clutch
to cool and should prevent further
clutch slip while the clutch pedal is
fully released. If this message
displays repeatedly, see your dealer.
Repeated clutch slip could cause
permanent damage.
Caution
The message TRANSMISSION IS
HOT —SLOW DOWN displays and
a chime sounds if the manual
transmission fluid is hot and
vehicle speed is high. Driving with
the manual transmission fluid
temperature high can damage the

same as 2 (Second).
To stop, let up on the accelerator
pedal and press the brake pedal. Just
before the vehicle stops, press the
clutch pedal and the brake pedal, and
shift to Neutral.
Neutral : Use this position when you
start or idle the engine. The shift lever
is in Neutral when it is centered in the
shift pattern, not in any gear.
R (Reverse) : To back up, press down
the clutch pedal, completely stop the
vehicle, and shift 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
Shifting to R (Reverse) while the
vehicle is moving forward could
damage the transmission. The
repairs would not be covered by the
vehicle warranty. Shift to
R (Reverse) only after the vehicle is
stopped.
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.

2022 - CRC - 10/12/21
DRIVING AND OPERATING 253
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.
.When ARM is deactivated, the gear
number is white.
.If no gear number is displayed while
the shift lever is in gear, service is
required. All rev matching will be
disabled and the malfunction
indicator lamp will be on. See
Malfunction Indicator Lamp (Check
Engine Light)099. The clutch and
manual transmission will continue
to operate normally.
ARM will also:
.Be active above 28 km/h (18 mph).
.Match engine speed up to
6100 rpm.
.Not operate when the accelerator
pedal is applied.
.Be disabled when the coolant
temperature is below 0 °C (32 °F).
Drive Systems
All-Wheel Drive
Vehicles with this feature always send
engine power to all four wheels. It is
fully automatic, and adjusts itself as
needed for road conditions.
Brakes
Electric Brake Boost
Vehicles equipped with electric brake
boost have hydraulic brake circuits
that are electronically controlled when
the brake pedal is applied during
normal operation. The system
performs routine tests and turns off
within a few minutes after the vehicle
is turned off. Noise may be heard
during this time. If the brake pedal is
pressed during the tests or when the
electric brake boost system is off, a
noticeable change in pedal force and
travel may be felt. This is normal.
Antilock Brake
System (ABS)
The Antilock Brake System (ABS)
helps prevent a braking skid and
maintain steering while braking hard.

DRIVING AND OPERATING 255
remains on. If the amber service
parking brake warning light is on, see
your dealer.
If the EPB is applied while the vehicle
is moving, the vehicle will decelerate
as long as the switch is pressed. If the
switch is pressed until the vehicle
comes to a stop, the EPB will remain
applied.
The vehicle may automatically apply
the EPB in some situations when the
vehicle is not moving. This is normal,
and is done to periodically check the
correct operation of the EPB system,
or at the request of other safety
functions that utilize the EPB.
If the EPB fails to apply, block the rear
wheels to prevent vehicle movement.
EPB Release
To release the EPB:1. Turn the ignition on or to ACC/ACCESSORY.
2. Apply and hold the brake pedal.
3. Press the EPB switch momentarily.
The EPB is released when the red
parking brake status light is off. If the amber service parking brake
warning light is on, release the EPB by
pressing and holding the EPB switch.
Continue to hold the switch until the
red parking brake status light is off.
If either light stays on after release is
attempted, see your dealer.
Caution
Driving with the parking brake on
can overheat the brake system and
cause premature wear or damage to
brake system parts. Make sure that
the parking brake is fully released
and the brake warning light is off
before driving.
If you are towing a trailer and parking
on a hill, see Driving Characteristics
and Towing Tips 0315.
Automatic EPB Release
The EPB will automatically release if
the vehicle is running, placed into
gear, and an attempt is made to drive
away. Avoid rapid acceleration when
the EPB is applied, to preserve parking
brake lining life. The EPB can also be used to prevent
roll back for vehicles with a manual
transmission taking off on a hill.
When no roll back is desired, an
applied EPB will allow both feet to be
used for the clutch and accelerator
pedals in preparation for starting the
vehicle moving in the intended
direction. In this case, there is no
need to press the switch to release
the EPB.
Brake Assist
Brake Assist detects rapid brake pedal
applications due to emergency braking
situations and provides additional
braking to activate the Antilock Brake
System (ABS) if the brake pedal is not
pushed hard enough to activate ABS
normally. Minor noise, brake pedal
pulsation, and/or pedal movement
during this time may occur. Continue
to apply the brake pedal as the driving
situation dictates. Brake Assist
disengages when the brake pedal is
released.

comfort and handling. This is the
standard mode. See“Mode Selection
Attributes” later in this section. When
Tour Mode is selected, no indicator
will display.
Sport Mode
Use this mode where road conditions
or personal preference demand a more
controlled response. When this mode
is selected, the vehicle immediately
downshifts. The vehicle also monitors
driving behaviors and automatically
enables Performance Shift Features
when spirited driving is detected. These features maintain lower
transmission gears to increase
available engine braking and improve
acceleration response. The vehicle will
exit this feature and return to normal
operation after a short period when
spirited driving is no longer detected.
The steering changes to provide more
precise control. If the vehicle has
Magnetic Ride Control, the suspension
changes to provide better cornering
performance.
See
“Mode Selection Attributes ”later
in this section.
Snow/Ice Mode
Use this mode for slippery surfaces to
help control wheel speed. This mode
can compromise the acceleration on
dry asphalt. This feature is not intended for use
when the vehicle is stuck in sand,
mud, or gravel. If the vehicle is stuck,
see
If the Vehicle Is Stuck 0227.
See “Mode Selection Attributes ”later
