soon as possible.
Retained Accessory Power (RAP)
These vehicle accessories may be used for up to
10 minutes after the engine is turned off.
.Audio System
.Power Windows, if equipped
.Sunroof, if equipped
The power windows and sunroof will continue to work
for up to 10 minutes or until any door is opened. The
radio will work when the key is in ON/RUN or ACC/
ACCESSORY. Once the key is turned from ON/RUN to
OFF/LOCK, the radio will continue to work for
10 minutes or until the driver's door is opened.
Starting the Engine
Place the transmission in the proper gear.
Automatic Transmission
Move the shift lever to P (Park) or N (Neutral). The
engine will not start in any other position. To restart the
vehicle when it is already moving, use N (Neutral) only.
Notice: Do not try to shift to P (Park) if the vehicle
is moving. If you do, you could damage the
transmission. Shift to P (Park) only when the vehicle
is stopped.

Manual Transmission
The shift lever should be in N (Neutral) and the parking
brake engaged. Hold the clutch pedal down to the floor
and start the engine. The vehicle will not start if the
clutch pedal is not all the way down.
Starting Procedure
1. With your foot off the accelerator pedal, turn theignition key to START. When the engine starts, let
go of the key. The idle speed will go down as the
engine warms. Do not race the engine immediately
after starting it. Operate the engine and
transmission gently to allow the oil to warm up and
lubricate all moving parts.
The vehicle has a Computer-Controlled Cranking
System. This feature assists in starting the engine
and protects components. If the ignition key is
turned to the START position, and then released
when the engine begins cranking, the engine will
continue cranking for a few seconds or until the
vehicle starts. If the engine does not start and the
key is held in START for many seconds, cranking
will be stopped after 15 seconds to prevent
cranking motor damage. To prevent gear damage,
this system also prevents cranking if the engine is
already running. Engine cranking can be stopped
by turning the ignition switch to ACC/ACCESSORY
or LOCK/OFF. Notice:
Cranking the engine for long periods of
time, by returning the key to the START position
immediately after cranking has ended, can overheat
and damage the cranking motor, and drain the
battery. Wait at least 15 seconds between each try,
to let the cranking motor cool down.
2. If the engine does not start after 5‐10 seconds, especially in very cold weather (below 0°F or
−18°C), it could be flooded with too much gasoline.
Push the accelerator pedal all the way to the floor
and holding it there as you hold the key in START
for a maximum of 15 seconds. Wait at least
15 seconds between each try, to allow the cranking
motor to cool. When the engine starts, let go of the
key and accelerator. If the vehicle starts briefly but
then stops again, repeat the procedure. This clears
the extra gasoline from the engine. Do not race the
engine immediately after starting it. Operate the
engine and transmission gently until the oil warms
up and lubricates all moving parts.
Notice: The engine is designed to work with the
electronics in the vehicle. If you add electrical parts
or accessories, you could change the way the
engine operates. Before adding electrical
equipment, check with your dealer/retailer. If you
do not, the engine might not perform properly.
Any resulting damage would not be covered by the
vehicle warranty.

Engine Coolant Heater
The engine coolant heater can provide easier starting
and better fuel economy during engine warm‐up in cold
weather condition at or below 0°F (−18°C). Vehicles
with am engine coolant heater should be plugged in at
least four hours before starting. An internal thermostat
in the plug-end of the cord may exist which will prevent
engine coolant heater operation at temperatures above
0°F (−18°C).
To Use the Engine Coolant Heater
1. Turn off the engine.
2. Open the hood and unwrap the electrical cord. Theelectrical cord is located on the passenger side of
the vehicle near the headlamp and the radiator.
3. Plug it into a normal, grounded 110-volt AC outlet.
{WARNING:
Plugging the cord into an ungrounded outlet could
cause an electrical shock. Also, the wrong kind of
extension cord could overheat and cause a fire.
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, to prevent damage.
The length of time the heater should remain plugged in
depends on several factors. Ask a dealer/retailer in the
area where you will be parking the vehicle for the best
advice on this.

Automatic Transmission Operation
If the vehicle has an automatic transmission, the shift
lever is located on the console between the seats.
There are several
different positions for the
automatic transmission.
P (Park): This position locks the front wheels. It is the
best position to use when starting the engine because
the vehicle cannot move easily.
{WARNING:
It is dangerous to get out of the vehicle if the shift
lever is not fully in P (Park) with the parking brake
firmly set. The vehicle can roll.
Do not leave the 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 the
vehicle will not move, even when you are on fairly
level ground, always set the parking brake and
move the shift lever to P (Park). See Shifting Into
Park (Automatic Transmission)
on page 3‑36.
If you are pulling a trailer, see Towing a Trailer
(Automatic Transmission)
on page 5‑32or
Towing a Trailer (Manual Transmission)
on
page 5‑40
.
3-28

Make sure the shift lever is fully in P (Park) before
starting the engine. The vehicle has an automatic
transmission shift lock control system. You have to fully
apply the regular brakes first and then press the shift
lever button before the vehicle can shift from P (Park)
when the ignition key is in ON/RUN. If the vehicle
cannot shift out of P (Park), ease pressure on the shift
lever and push the shift lever all the way into P (Park)
as you maintain brake application. Then press the shift
lever button and then move the shift lever into another
gear. SeeShifting Out of Park (Automatic Transmission)
on page 3‑37.
R (Reverse): Use this gear to back up.
Notice: 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.
To rock your vehicle back and forth to get out of snow,
ice, or sand without damaging the transmission, see If
Your Vehicle is Stuck in Sand, Mud, Ice, or Snow
on
page 5‑23. N (Neutral):
In this position, the engine does not
connect with the wheels. To restart the engine when the
vehicle is already moving, use N (Neutral) only. Also,
use N (Neutral) when the vehicle is being towed.
{WARNING:
Shifting into a drive gear while the engine is
running at high speed is dangerous. Unless your
foot is firmly on the brake pedal, the vehicle could
move very rapidly. You could lose control and hit
people or objects. Do not shift into a drive gear
while the engine is running at high speed.
Notice: Shifting out of P (Park) or N (Neutral) with
the engine running at high speed may damage the
transmission. The repairs would not be covered by
the vehicle warranty. Be sure the engine is not
running at high speed when shifting the vehicle.
3-29

D (Drive):This position is for normal driving with the
automatic transmission. It provides the best fuel
economy. If you need more power for passing and
you are:
.Going less than about 35 mph (55 km/h), push
the accelerator pedal about halfway down.
.Going about 35 mph (55 km/h), push the
accelerator all the way down.
Downshifting the transmission in slippery road
conditions could result in skidding, see “Skidding”
under Loss of Control on page 5‑15.
I (Intermediate): This position is also used for normal
driving. However, it reduces vehicle speed without using
the brakes for slight downgrades where the vehicle
would otherwise accelerate due to steepness of grade.
If constant upshifting or downshifting occurs while
driving up steep hills, this position can be used to
prevent repetitive types of shifts. You might choose
I (Intermediate) instead of D (Drive) when driving on
hilly, winding roads and when towing a trailer, so that
there is less shifting between gears. PERFORMANCE SHIFTING:
If the vehicle has this
feature, it can detect a change in driving patterns
while in the Intermediate position. If you make an
aggressive driving maneuver, the vehicle's transmission
automatically shifts to the lowest possible gear to
maximize vehicle performance. The vehicle will
automatically return to normal operation when you
return to normal driving patterns.
L (Low): This position reduces vehicle speed more than
I (Intermediate) without actually using the brakes. You
can use it on very steep hills, or in deep snow or mud.
If the shift lever is put in L (Low), the transmission will
not shift into L (Low) until the vehicle is going slowly
enough.
Notice: Spinning the tires or holding the vehicle in
one place on a hill using only the accelerator pedal
may damage the transmission. The repair will not be
covered by the vehicle warranty. If you are stuck, do
not spin the tires. When stopping on a hill, use the
brakes to hold the vehicle in place.

Manual Transmission Operation
This is the shift pattern for standard models.
This is the shift pattern for SS models.
Here is how to operate the manual transmission:
Notice: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.
1 (First): Press the clutch pedal and shift into 1 (First).
Then, slowly let up on the clutch pedal as you press the
accelerator pedal.
You can shift into 1 (First) when the vehicle is traveling
less than 20 mph (32 km/h). If you have come to a
complete stop and it is hard to shift into 1 (First), put the
shift lever in N (Neutral) and let up on the clutch pedal.
Press the clutch pedal back down. Then shift into
1 (First).
3-31

2 (Second):Press the clutch pedal as you let up on the
accelerator pedal and shift into 2 (Second). Then, slowly
let up on the clutch pedal as you press the accelerator
pedal.
3 (Third), 4 (Fourth) and 5 (Fifth): Shift into 3 (Third),
4 (Fourth) and 5 (Fifth) the same way you do for
2 (Second). Slowly let up on the clutch pedal as
you press the accelerator pedal down.
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
N (Neutral).
N (Neutral): Use this position when you start or idle the
engine.
R (Reverse): To back up, press down the clutch pedal
and shift into R (Reverse).
For SS models, lift upwards on the ring located on the
underside of the shift knob to shift into R (Reverse). Notice:
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.
Also, use R (Reverse), along with the parking brake, for
parking the vehicle.
Shift Speeds
{WARNING:
If you skip a gear when you downshift, 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 you downshift.
