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 PARK (P) or NEUTRAL (N). The
engine will not start in any other position -- this is a
safety feature. To restart when you are already moving,
use NEUTRAL (N) only.
Notice:Do not try to shift to PARK (P) if your
vehicle is moving. If you do, you could damage the
transmission. Shift to PARK (P) only when your
vehicle is stopped.
Manual Transmission
The shift lever should be in neutral position and the
parking brake engaged. Hold the clutch pedal down to
the oor and start the engine. Your vehicle will not
start if the clutch pedal is not all the way down. That is
a safety feature.

Manual Transmission Operation
This is your shift pattern.
Here is how to operate your manual 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 20 mph (32 km/h). If you have 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 pedal. Press
the clutch pedal back down. Then shift into FIRST (1).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) and FIFTH (5):Shift into
THIRD (3), FOURTH (4) and FIFTH (5) 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.
REVERSE (R):To back up, press down the clutch
pedal and shift into REVERSE (R). Let up on the clutch
pedal slowly while pressing the accelerator pedal.
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.
Also, use REVERSE (R), along with the parking brake,
for parking your vehicle.

Shifting Out of PARK (P) (Automatic
Transmission)
This vehicle is equipped with an electronic shift lock
release system. The shift lock release is designed to:
Prevent ignition key removal unless the shift
lever is in PARK (P) with the shift lever button fully
released, and
Prevent movement of the shift lever out of PARK (P)
unless the ignition is in ON/RUN or ACC/
ACCESORY and the regular brake pedal is applied.
The shift lock release is always functional except in the
case of a an uncharged or low voltage (less than 9 volt)
battery.
If your vehicle has an uncharged battery or a battery
with low voltage, try charging or jump starting the
battery. SeeJump Starting on page 5-34for more
information.To shift out of PARK (P):
1. Apply the brake pedal.
2. Then press the shift lever button.
3. Move the shift lever to the desired position.
If you still are unable to shift out of PARK (P):
1. Fully release the shift lever button.
2. While holding down the brake pedal, press the shift
lever button again.
3. Move the shift lever to the desired position.
If you still cannot move the shift lever from PARK (P),
consult your dealer/retailer or a professional towing
service.
Parking Your Vehicle
Before leaving your vehicle, fully press the clutch pedal
down, move the shift lever into REVERSE (R), and
rmly apply the parking brake. Once the shift lever has
been placed in REVERSE (R) with the clutch pedal
pressed down, you can turn the ignition key to
OFF/LOCK, remove the key and release the clutch
pedal. SeeManual Transmission Operation on
page 2-30.

Using Cruise Control on Hills
How well the cruise control will work on hills depends
upon the vehicle speed, load, and the steepness of the
hills. When going up steep hills, you might have to
step on the accelerator pedal to maintain the vehicle’s
speed. When going downhill, you might have to brake or
shift to a lower gear to keep the vehicle’s speed
down. Applying the brake will turn off the cruise control.
Many drivers nd this to be too much trouble and do
not use cruise control on steep hills.
Ending Cruise Control
There are two ways to end cruise control:
Step lightly on the brake pedal or the clutch pedal if
the vehicle has a manual transmission. This will
only end the current cruise control session.
Press the cruise controlJon/off button to turn the
system completely off.
Erasing Speed Memory
The cruise control set speed memory is erased when
the cruise control or the ignition is turned off.

Checking Engine Oil
It is a good idea to check the engine oil every time you
get fuel. In order to get an accurate reading, the oil
must be warm and the vehicle must be on level ground.
The engine oil dipstick handle is a yellow loop. See
Engine Compartment Overview on page 5-12for
the location of the engine oil dipstick.
1. Turn off the engine and give the oil several minutes
to drain back into the oil pan. If you do not do this,
the oil dipstick might not show the actual level.
2. Pull the dipstick and clean it with a paper towel or
cloth, then push it back in all the way. Remove it
again, keeping the tip down and check the level.
5-13

Manual Transmission Fluid
It is not necessary to check the manual transmission
uid level. A transmission uid leak is the only reason for
uid loss. If a leak occurs, take the vehicle to a
dealer/retailer for service. Have it repaired as soon as
possible. You may also have your uid level checked by
your dealer/retailer when you have your oil changed.
SeeRecommended Fluids and Lubricants on page 6-12
for the proper uid to use.
Hydraulic Clutch
The hydraulic clutch linkage in your vehicle is
self-adjusting. This system does not have its own
reservoir. It receives uid from the brake master cylinder
reservoir.
SeeBrakes on page 5-30for more information.
Engine Coolant
The cooling system in your vehicle is lled with
DEX-COOL®engine coolant. This coolant is designed
to remain in your vehicle for ve years or 150,000 miles
(240 000 km), whichever occurs rst, if you add only
DEX-COOL
®extended life coolant.
The following explains your cooling system and how to
add coolant when it is low. If you have a problem
with engine overheating, seeEngine Overheating on
page 5-22.
A 50/50 mixture of clean, drinkable water and
DEX-COOL
®coolant will:
Give freezing protection down to−34°F (−37°C).
Give boiling protection up to 265°F (129°C).
Protect against rust and corrosion.
Help keep the proper engine temperature.
Let the warning lights and gages work as they
should.
Notice:Using coolant other than DEX-COOL
®may
cause premature engine, heater core, or radiator
corrosion. In addition, the engine coolant may
require changing sooner, at the rst maintenance
service after each 30,000 miles (50 000 km) or
24 months, whichever occurs rst. Any repairs
would not be covered by your warranty. Always use
DEX-COOL
®(silicate-free) coolant in your vehicle.
5-19

Brakes
Brake Fluid
The brake master cylinder
and, on manual
transmission vehicles, the
clutch hydraulic system
use the same reservoir.
The reservoir is lled with
DOT-3 brake uid.
SeeEngine Compartment Overview on page 5-12for
the location of the reservoir.
There are only two reasons why the brake uid level in
the reservoir might go down. The rst is that the
brake uid goes down to an acceptable level during
normal brake lining wear. When new linings are put in,
the uid level goes back up. The other reason is
that uid is leaking out of the brake and/or clutch
hydraulic system. If it is, you should have the brake
and/or clutch hydraulic system xed, since a leak means
that sooner or later the brakes and/or clutch will not
work well.It is not a good idea to top off the brake/clutch uid.
Adding uid will not correct a leak. If uid is added when
the brake linings are worn, there will be too much uid
when new brake linings are installed. Add or remove
uid, as necessary, only when work is done on the
brake/clutch hydraulic system.
{CAUTION:
If your vehicle has too much brake uid, it can
spill on the engine. The uid will burn if the
engine is hot enough. You or others could be
burned, and your vehicle could be damaged.
Add brake uid only when work is done on the
brake and/or clutch hydraulic system.
When the brake uid falls to a low level, the brake
warning light will come on. SeeBrake System Warning
Light on page 3-33.
