AUTOMATIC TRANSMISSION OPERATION (IF EQUIPPED)
Driving with a 6–speed automatic transmission
Your vehicle has been designed to improve fuel economy by reducing
fuel usage while coasting or decelerating. When you take your foot off
the accelerator pedal and the vehicle begins to slow down the torque
converter clutch locks up and aggressively shuts off fuel flow to the
engine while decelerating. This fuel economy benefit may be perceived
as a light to medium braking sensation when removing your foot from
the accelerator pedal.
This vehicle is equipped with an adaptive transmission shift strategy. The
adaptive transmission shift strategy offers the optimal transmission
operation and shift quality. When the engine is turned off, the shift data
which includes the adaptive information will be stored automatically in
the powertrain control module (PCM). If the battery is disconnected for
any reason, the stored information from the last time the key was turned
to off will be read. This way, no information will be lost with any battery
removal or battery disconnect.
P (Park)
This position locks the transmission
and prevents the rear wheels from
turning.
To put your vehicle in gear:
1. Start the engine.
2. Press the brake pedal.
3. Move the gearshift lever into the
desired gear.
To put your vehicle in P (Park):
1. Come to a complete stop.
2. Move the gearshift lever and securely latch it in P (Park).
WARNING:Always set the parking brake fully and make sure
the gearshift is latched in P (Park). Turn the ignition to the off
position and remove the key whenever you leave your vehicle.
R (Reverse)
With the gearshift lever in R (Reverse), the vehicle will move backward.
Always come to a complete stop before shifting into and out of R
(Reverse).

•Press the accelerator to the floor.
•Allows transmission to select an appropriate gear.
If your vehicle gets stuck in mud or snow
If your vehicle gets stuck in mud or snow, it may be rocked out by
shifting between forward and reverse gears, stopping between shifts in a
steady pattern. Press lightly on the accelerator in each gear.
Do not rock the vehicle if the engine is not at normal operating
temperature or damage to the transmission may occur.
Do not rock the vehicle for more than a minute or damage to the
transmission and tires may occur, or the engine may overheat.
MANUAL TRANSMISSION OPERATION (IF EQUIPPED)
Using the clutch
Manual transmission vehicles have a starter interlock that prevents
cranking the engine unless the clutch pedal is fully pressed.
To start the vehicle:
1. Make sure the parking brake is fully set.
Driving

2. Press the clutch pedal to the
floor, then put the gearshift lever in
the neutral position.
3. Start the engine.
4. Press the brake pedal and move
the gearshift lever to the desired
gear; 1 (First) or R (Reverse).
5. Release the parking brake, then slowly release the clutch pedal while
slowly pressing on the accelerator.
During each shift, the clutch pedal must be fully pressed to the floor.
Make sure the floor mat is properly positioned so it doesn’t interfere with
the full extension of the clutch pedal.
Failure to fully press the clutch pedal to the floor may cause
increased shift efforts, prematurely wear transmission
components or damage the transmission.
Do not drive with your foot resting on the clutch pedal or use the
clutch pedal to hold your vehicle at a standstill while waiting on a
hill. These actions will severely reduce the life of the clutch and
could nullify a clutch warranty claim.
Recommended shift speeds
Do not downshift into 1 (First) when your vehicle is moving
faster than 15 mph (24 km/h). This may damage the clutch and/or
transmission.

3. Shift into R (Reverse) by pushing
the gearshift knob down, then
moving the lever fully to the left,
then forward.
Note:The gearshift lever can only be moved to R (Reverse) by pushing
the knob down before shifting to reverse. This is a lockout feature which
protects the transmission from accidentally engaging R (Reverse) when
intending to select 1 (First).
If R (Reverse) is not fully engaged, press the clutch pedal down and
return the gearshift to the neutral position. Release the clutch pedal for
a moment, then press it down and shift to R (Reverse) again.
Parking your vehicle
1. Apply the brake and shift into the neutral position.
2. Fully apply the parking brake, hold the clutch pedal down, then shift
into 1 (First).
3. Turn the ignition off.
WARNING:Do not park your vehicle in Neutral, it may move
unexpectedly and injure someone. Use 1 (First) gear and set the
parking brake fully.
REVERSE SENSING SYSTEM (IF EQUIPPED)
The reverse sensing system (RSS) sounds a tone to warn the driver of
obstacles near the rear bumper when the R (Reverse) is selected and the
vehicle is moving at speeds less than 3 mph (5 km/h). The system is not
effective at speeds above 3 mph (5 km/h) and may not detect certain
angular or moving objects.
WARNING:To help avoid personal injury, please read and
understand the limitations of the reverse sensing system as
contained in this section. Reverse sensing is only an aid for some
(generally large and fixed) objects when moving in reverse on a flat
surface at “parking speeds”. Inclement weather may also affect the
function of the RSS; this may include reduced performance or a false
activation.

WARNING:To help avoid personal injury, always use caution
when in R (Reverse) and when using the RSS.
WARNING:This system is not designed to prevent contact with
small or moving objects. The system is designed to provide a
warning to assist the driver in detecting large stationary objects to
avoid damaging the vehicle. The system may not detect smaller
objects, particularly those close to the ground.
WARNING:Certain add-on devices such as large trailer hitches,
bike or surfboard racks and any device that may block the
normal detection zone of the RSS system may create false beeps.
The RSS detects obstacles up to six
feet (two meters) from the rear
bumper with a decreased coverage
area at the outer corners of the
bumper, (refer to the figures for
approximate zone coverage areas).
As you move closer to the obstacle,
the rate of the tone increases. When
the obstacle is less than 10 inches
(25.0 cm) away, the tone will sound
continuously. If the RSS detects a
stationary or receding object further
than 10 inches (25.0 cm) from the
side of the vehicle, the tone will
sound for only three seconds. Once
the system detects an object
approaching, the tone will sound
again.
While receiving a warning the radio volume will be reduced to a
predetermined level. After the warning goes away, the radio will return
to the previous value.
