To Use The Engine Coolant Heater
1. Turn off the engine.
2. Open the hood and unwrap the electrical cord.
The electrical cord is located on the driver’s side
of the engine compartment, in front of the coolant
surge tank.
3. Plug it into a normal, grounded 110-volt AC outlet.
{CAUTION:
Plugging the cord into an ungrounded outlet
could cause an electrical shock. Also, the
wrong kind of extension cord could overheat
and cause a re. You could be seriously
injured. Plug the cord into a properly grounded
three-prong 110-volt AC outlet. If the cord will
not reach, use a heavy-duty three-prong
extension cord rated for at least 15 amps.4. Before starting the engine, be sure to unplug and
store the cord as it was before to keep it away
from moving engine parts. If you do not it could be
damaged.
How long should you keep the coolant heater plugged
in? The answer depends on the outside temperature, the
kind of oil you have, and some other things. Instead
of trying to list everything here, we ask that you contact
your dealer in the area where you will be parking
your vehicle. The dealer can give you the best advice
for that particular area.

Automatic Transmission Operation
There are several different
positions for your shift
lever.
PARK (P):This position locks your rear wheels. It is
the best position to use when you start your engine
because your vehicle cannot move easily.{CAUTION:
It is dangerous to get out of your vehicle if the
shift lever is not fully in PARK (P) with the
parking brake rmly set. Your vehicle can roll.
Do not leave your vehicle when the engine is
running unless you have to. If you have left the
engine running, the vehicle can move suddenly.
You or others could be injured. To be sure your
vehicle will not move, even when you are on
fairly level ground, always set your parking
brake and move the shift lever to PARK (P). See
Shifting Into Park (P) (Automatic Transmission)
on page 2-33.
Be sure the shift lever is fully in PARK (P) before
starting the engine. Your vehicle has an automatic
transmission shift lock control system.
2-26

You have to fully apply your regular brakes before you
can shift from PARK (P) when the vehicle is running.
If you cannot shift out of PARK (P), ease pressure
on the shift lever – push the shift lever all the way into
PARK (P) and release the shift lever button as you
maintain brake application. Then press the shift lever
button and move the shift lever into the gear you wish.
SeeShifting Out of Park (P) (Automatic Transmission)
on page 2-35.
REVERSE (R):Use this gear to back up.
Notice:Shifting to REVERSE (R) while your vehicle
is moving forward could damage the transmission.
The repairs would not be covered by your warranty.
Shift to REVERSE (R) only after your vehicle is
stopped.
To rock your vehicle back and forth to get out of snow,
ice, or sand without damaging your transmission,
seeIf Your Vehicle is Stuck in Sand, Mud, Ice, or Snow
on page 4-32.
NEUTRAL (N):In this position, your engine does not
connect with the wheels. To restart when you are
already moving, use NEUTRAL (N) only. If your vehicle
needs towing, seeTowing Your Vehicle on page 4-38.
{CAUTION:
Shifting into a drive gear while your engine is
running at high speed is dangerous. Unless
your foot is rmly on the brake pedal, your
vehicle could move very rapidly. You could
lose control and hit people or objects. Do not
shift into a drive gear while your engine is
running at high speed.
Notice:Shifting out of PARK (P) or NEUTRAL (N)
with the engine running at high speed may damage
the transmission. The repairs would not be covered
by your warranty. Be sure the engine is not running
at high speed when shifting your vehicle.
AUTOMATIC OVERDRIVE (D):This position is for
normal driving.
SPORT MODE (S):When in SPORT MODE (S), the
transmission will work as an automatic until you use the
Manual Paddle Shift Controls, which activates the driver
manual gear selection. See Manual Paddle Shift later in
this section. While in automatic SPORT MODE (S), the
transmission computer determines when the vehicle is
being driven in a competitive manner and will select and
hold the transmission in lower gears and have more
noticeable upshifts for sportier vehicle performance.
2-27

Manual Paddle Shift
While in SPORT MODE (S), the paddles located on the
steering wheel, can be used to manually up-shift or
down-shift the transmission.
While in SPORT MODE (S) mode, push the paddle
above the steering wheel spokes to up-shift to the next
gear, or pull on the paddle behind the steering wheel
spokes to down-shift to the next gear.To use the system, shift from PARK (P) to SPORT
MODE (S) while stopped and with the engine running,
or from DRIVE (D) with the vehicle moving. When
accelerating your vehicle from a stop in snowy and icy
conditions, you may want to shift to second (2) or
third (3) gear. A higher gear allows you to gain more
traction on slippery surfaces. If the Traction Control
is active, upshifts are delayed to increase your control
of the vehicle. SeeTraction Control System (TCS)
on page 4-9.
While the Manual Paddle Shift gear selection system is
active, the transmission will automatically downshift
through the gears as the vehicle slows. The transmission
will select second gear as the vehicle stops. From a stop,
the vehicle will start from and hold second (2) gear unless
the driver manually paddle shifts into a different gear or
selects DRIVE (D). The driver can select rst (1) gear for
maximum acceleration from a stop.
2-28

When you up-shift or
down-shift when using
the Manual Paddle
Shift Feature while in the
SPORT MODE (S),
the current gear will be
displayed in the Driver
Information (DIC), or the
Head-Up Display (HUD),
if the vehicle has this
feature.
The Manual Paddle Shift system will not allow either an
up-shift or a down-shift if the vehicle speed is too
fast or too slow, nor will it allow a start from fourth (4) or
higher gear
If up-shifting does not occur when needed, the vehicle
speed will be limited to protect the engine.
The transmission will also automatically down-shift as
the vehicle slows down and comes to a stop.
When the transmission gear does not respond to a shift
change, the DIC will show an X over the gear display.When a requested shift is
denied due to the speed
restrictions shown, the DIC
will momentarily show
an X over the gear display
and a chime will sound.
If the vehicle has HUD, and the transmission gear
does not respond to a shift change, then a chime will
sound and the HUD will momentarily show an X over the
gear display.
Manual Paddle Shift operation is available for use with
Cruise Control, seeCruise Control on page 3-11for
more information.
2-29

The vehicle speeds required for Manual Paddle Shift
up-shifts depend on several vehicle inputs, which
will vary the allowed up-shift speed by a few mph (km/h).
Up-shifts to fourth (4) gear require approximately
22 mph (35 km/h).
Up-shifts to fth (5) gear require approximately
28 mph (45 km/h).
Up-shifts to sixth (6) gear require approximately
41 mph (65 km/h).
To prevent damage to the powertrain, Manual Paddle
downshifts to a lower gear cannot be done above certain
speeds. The maximum speed allowed for downshifting
of gears one (1) through fourth (4) are:
Into fourth (4) gear over 168 mph (270 km/h)
Into third (3) gear over 124 mph (200 km/h)
Into second (2) gear over 81 mph (130 km/h)
Into rst (1) gear over 45 mph (72 km/h).
If the driver does not request an upshift as the engine
speed approaches fuel shut off RPM, the engine
speed will be limited to protect the engine. See
Tachometer on page 3-34for more information.
Manual Transmission Operation
This is the shift pattern for
the six-speed manual
transmission.
Here is how to operate your transmission:
FIRST (1):Press the clutch pedal and shift into
FIRST (1). Then slowly let up on the clutch pedal as
you press the accelerator pedal.
You can shift into FIRST (1) when you are going less
than 40 mph (64 km/h). If you come to a complete stop
and it is hard to shift into FIRST (1), put the shift
lever in NEUTRAL and let up on the clutch. Press the
clutch pedal back down. Then shift into FIRST (1).
2-30

SECOND (2):Press the clutch pedal as you let up on
the accelerator pedal and shift into SECOND (2).
Then, slowly let up on the clutch pedal as you press the
accelerator pedal.
THIRD (3), FOURTH (4), FIFTH (5) and SIXTH (6):Shift
into THIRD (3), FOURTH (4), FIFTH (5) and SIXTH (6)
the same way you do for SECOND (2). Slowly let up on
the clutch pedal as you press the accelerator pedal.
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
your engine. Your shift lever is in NEUTRAL when it is
centered in the shift pattern, not in any gear.
REVERSE (R):To back up, press down the clutch
pedal and shift into REVERSE (R). Just apply pressure
to get the lever past FIFTH (5) and SIXTH (6) into
REVERSE (R). Let up on the clutch pedal slowly while
pressing the accelerator pedal.
Your six-speed manual transmission has a feature that
allows you to safely shift into REVERSE (R) while
the vehicle is rolling at less than 3 mph (5 km/h). You
will be locked out if you try to shift into REVERSE (R)
while your vehicle is moving faster than 3 mph (5 km/h).Shift Speeds (Manual Transmission)
{CAUTION:
If you skip a gear when you downshift, you could
lose control of your vehicle. You could injure
yourself or others. Do not shift down more than
one gear at a time when you downshift.
This chart shows when to shift to the next higher gear
for the best fuel economy.

1to2 2to3 3to4 4to5 5to6
All
Engines15 (24) 25 (40) 40 (64) 45 (72) 50 (80)
If your engine speed drops below 900 rpm, or if the
engine is not running smoothly, you should downshift
to the next lower gear. You may have to downshift
two or more gears to keep the engine running smoothly
or for good engine performance.
Notice:When shifting gears, do not move the
shift lever around unnecessarily. This may damage
the transmission. Shift directly into the next gear.
2-31

One to Four Shift Light
(Manual Transmission)
When this light comes on,
you can only shift from
FIRST (1) to FOURTH (4)
instead of FIRST (1) to
SECOND (2).
You must complete the shift into FOURTH (4) to turn off
this feature. This helps you get the best possible fuel
economy.
After shifting to FOURTH (4), you may downshift to a
lower gear.
Notice:Forcing the shift lever into any gear except
FOURTH (4) when the 1 TO 4 SHIFT light comes
on may damage the transmission. Shift only from
FIRST (1) to FOURTH (4) when the light comes on.
This light will come on when:
The engine coolant temperature is higher than
169°F (76°C),
you are going 15 to 19 mph (24 to 31 km/h) and
you are 21 percent throttle or less.
Downshifting (Manual Transmission)
Do not downshift into the gear shown below at a speed
greater than shown in the table:
FIRST (1) 50 mph (80 km/h)
SECOND (2) 74 mph (119 km/h)
THIRD (3) 101 mph (163 km/h)
FOURTH (4) 130 mph (209 km/h)
Notice:If you skip more than one gear when you
downshift, or if you race the engine when you
release the clutch pedal while downshifting, you
could damage the engine, clutch, driveshaft or the
transmission. Do not skip gears or race the
engine when downshifting.
The six-speed transmission has a spring that centers
the shift lever near THIRD (3) and FOURTH (4).
This spring helps you know which gear you are in when
you are shifting. Be careful when shifting from
FIRST (1) to SECOND (2) or downshifting from
SIXTH (6) to FIFTH (5). The spring will try to pull the
shift lever toward FOURTH (4) and THIRD (3).
Make sure you move the lever into SECOND (2) or
FIFTH (5). If you let the shift lever move in the direction
of the pulling, you may end up shifting from FIRST (1)
to FOURTH (4) or from SIXTH (6) to THIRD (3).
2-32

Parking Brake
The parking brake lever is located to the right of the
center console.
To set the parking brake, hold the brake pedal down.
Pull the parking brake lever up. If the ignition is on,
the brake system warning light will come on.
To release the parking brake, hold the brake pedal
down. Then push the release button in as you move
the parking brake lever all the way down.
Notice:Driving with the parking brake on can
overheat the brake system and cause premature
wear or damage to brake system parts. Verify that
the parking brake is fully released and the brake
warning light is off before driving.
Shifting Into Park (P)
(Automatic Transmission)
{CAUTION:
It can be dangerous to get out of your vehicle
if the shift lever is not fully in PARK (P) with
the parking brake rmly set. Your vehicle can
roll. If you have left the engine running, the
vehicle can move suddenly. You or others
could be injured. To be sure your vehicle will
not move, even when you are on fairly level
ground, use the steps that follow.
1. Hold the brake pedal down with your right foot and
set the parking brake.
2. Move the shift lever into PARK (P) by holding in the
button on the lever and pushing the lever all the
way toward the front of the vehicle.
3. Press the ACC button (ignition switch) to turn the
engine off.
2-33

Leaving Your Vehicle With the Engine
Running (Automatic Transmission)
{CAUTION:
It can be dangerous to leave your vehicle with
the engine running. Your vehicle could move
suddenly if the shift lever is not fully in
PARK (P) with the parking brake rmly set.
And, if you leave the vehicle with the engine
running, it could overheat and even catch re.
You or others could be injured. Do not leave
your vehicle with the engine running.
If you have to leave your vehicle with the engine running,
be sure your vehicle is in PARK (P) and your parking
brake is rmly set before you leave it. After you have
moved the shift lever into PARK (P), hold down the
regular brake pedal. See if you can move the shift lever
away from PARK (P) without rst pulling it toward you. If
you can, it means that the shift lever was not fully locked
into PARK (P).
Torque Lock (Automatic Transmission)
If you are parking on a hill and you do not shift your
transmission into PARK (P) properly, the weight of the
vehicle may put too much force on the parking pawl in the
transmission. You may nd it difficult to pull the shift lever
out of PARK (P). This is called “torque lock.” To prevent
torque lock, set the parking brake and then shift into
PARK (P) properly before you leave the driver’s seat.
To nd out how, see “Shifting Into PARK (P)” listed
previously in this section.
When you are ready to drive, move the shift lever out of
PARK (P) before you release the parking brake.
If torque lock does occur, you may need to have another
vehicle push yours a little uphill to take some of the
pressure from the transmission parking pawl, so you can
pull the shift lever out of PARK (P).
