Exhaust Gas
WARNING!
Exhaust gases can injure or kill. They contain carbon
monoxide (CO), which is colorless and odorless.
Breathing it can make you unconscious and can even-
tually poison you. To avoid breathing (CO), follow
these safety tips:
•Do not run the engine in a closed garage or in
confined areas any longer than needed to move your
vehicle in or out of the area.
• If you are required to drive with the trunk/liftgate/
rear doors open, make sure that all windows are
closed and the climate control BLOWER switch is set
at high speed. DO NOT use the recirculation mode.
• If it is necessary to sit in a parked vehicle with the
engine running, adjust your heating or cooling con-
trols to force outside air into the vehicle. Set the
blower at high speed.
The best protection against carbon monoxide entry into the
vehicle body is a properly maintained engine exhaust
system.
Whenever a change is noticed in the sound of the exhaust
system, when exhaust fumes can be detected inside the vehicle, or when the underside or rear of the vehicle is
damaged, have a competent mechanic inspect the complete
exhaust system and adjacent body areas for broken, dam-
aged, deteriorated, or mispositioned parts. Open seams or
loose connections could permit exhaust fumes to seep into
the passenger compartment. In addition, inspect the ex-
haust system each time the vehicle is raised for lubrication
or oil change. Replace as required.
Safety Checks You Should Make Inside The Vehicle
Seat Belts
Inspect the seat belt system periodically, checking for cuts,
frays, and loose parts. Damaged parts must be replaced
immediately. Do not disassemble or modify the system.
Front seat belt assemblies must be replaced after a collision.
Rear seat belt assemblies must be replaced after a collision
if they have been damaged (i.e., bent retractor, torn web-
bing, etc.). If there is any question regarding seat belt or
retractor condition, replace the seat belt.
Air Bag Warning Light
The Air Bag warning lightwill turn on for four to
eight seconds as a bulb check when the ignition switch
is first turned to ON/RUN. If the light is either not on
during starting, stays on, or turns on while driving, 5

WARNING!(Continued)
vehicle properly parked with the engine off, fully
depress the accelerator, the brake, and the clutch
pedal (if present) to check for interference. If your
floor mat interferes with the operation of any pedal,
or is not secure to the floor, remove the floor mat
from the vehicle and place the floor mat in your
trunk.
• ONLY use the passenger ’s side floor mat on the
passenger ’s side floor area.
• ALWAYS make sure objects cannot fall or slide into
the driver ’s side floor area when the vehicle is
moving. Objects can become trapped under accelera-
tor, brake, or clutch pedals and could cause a loss of
vehicle control.
• NEVER place any objects under the floor mat (e.g.,
towels, keys, etc.). These objects could change the
position of the floor mat and may cause interference
with the accelerator, brake, or clutch pedals.
• If the vehicle carpet has been removed and re-
installed, always properly attach carpet to the floor
and check the floor mat fasteners are secure to the
vehicle carpet. Fully depress each pedal to check for

WARNING! (Continued)
interference with the accelerator, brake, or clutch
pedals then re-install the floor mats.
• It is recommended to only use mild soap and water
to clean your floor mats. After cleaning, always check
your floor mat has been properly installed and is
secured to your vehicle using the floor mat fasteners
by lightly pulling mat.
Periodic Safety Checks You Should Make Outside
The Vehicle
Tires
Examine tires for excessive tread wear and uneven wear
patterns. Check for stones, nails, glass, or other objects
lodged in the tread or sidewall. Inspect the tread for cuts
and cracks. Inspect sidewalls for cuts, cracks, and bulges.
Check the wheel bolts for tightness. Check the tires (includ-
ing spare) for proper cold inflation pressure.
Lights
Have someone observe the operation of brake lights and
exterior lights while you work the controls. Check turn
signal and high beam indicator lights on the instrument
panel.

mended viscosity and quality grades, refer to “Fluids And
Lubricants” in “Technical Specifications”.
CAUTION!
Never use Non-Detergent Oil or Straight Mineral Oil
in the engine or damage may result.
NOTE: A new engine may consume some oil during its
first few thousand miles (kilometers) of operation. This
should be considered a normal part of the break-in and not
interpreted as a problem. Please check your oil level with
the engine oil indicator often during the break in period.
Add oil as required.
PARKING BRAKE
Before leaving the vehicle, make sure that the parking
brake is fully applied.
The parking brake lever is located on the outboard side of
the driver ’s seat. To apply the parking brake, pull the lever
up as firmly as possible. To release the parking brake, pull
the lever up slightly, push the release button with your
thumb, then lower the lever completely. When the parking brake is applied with the ignition switch
in the MAR (ACC/ON/RUN) position, the Brake Warning
Light in the instrument cluster will illuminate.
When parking on a hill, it is important to turn the front
wheels toward the curb on a downhill grade and away
from the curb on an uphill grade. The parking brake
should always be applied whenever the driver is not in the
vehicle.

WARNING!
•Never use the PARK position as a substitute for the
parking brake. Always apply the parking brake fully
when exiting the vehicle to guard against vehicle
movement and possible injury or damage.
• Your vehicle could move and injure you and others if
it is not in PARK. Check by trying to move the gear
selector out of PARK with the brake pedal released.
Make sure the transmission is in PARK before exit-
ing the vehicle.
• It is dangerous to shift out of PARK or NEUTRAL if
the engine speed is higher than idle speed. If your
foot is not firmly pressing the brake pedal, the
vehicle could accelerate quickly forward or in re-
verse. You could lose control of the vehicle and hit
someone or something. Only shift into gear when the
engine is idling normally and your foot is firmly
pressing the brake pedal.
• Unintended movement of a vehicle could injure
those in or near the vehicle. As with all vehicles, you
should never exit a vehicle while the engine is
running. Before exiting a vehicle always come to a
complete stop, then apply the parking brake, shift

WARNING! (Continued)
the transmission into PARK, turn the engine OFF,
and remove the ignition key. Once the key is re-
moved, the transmission is locked in PARK, securing
the vehicle against unwanted movement.
• When exiting the vehicle, always remove the ignition
key from the vehicle and lock the vehicle.
• Never leave children alone in a vehicle, or with
access to an unlocked vehicle. Allowing children to
be in a vehicle unattended is dangerous for a number
of reasons. A child or others could be seriously or
fatally injured. Children should be warned not to
touch the parking brake, brake pedal or the trans-
mission gear selector.
• Do not leave the ignition key in or near the vehicle
(or in a location accessible to children). A child could
operate power windows, other controls, or move the
vehicle.
The following indicators should be used to ensure that you
have engaged the transmission into the PARK position:
• When shifting into PARK, firmly move the gear selector
all the way forward and to the left until it stops and is
fully seated.
144 STARTING AND OPERATING

Power Steering Fluid Check
Checking the power steering fluid level at a defined service
interval is not required. The fluid should be checked at
every oil change if a leak is suspected, abnormal noises are
apparent, and/or the system is not functioning as antici-
pated. Coordinate inspection efforts through an authorized
dealer.
WARNING!
Fluid level should be checked on a level surface and
with the engine off to prevent injury from moving
parts and to ensure accurate fluid level reading. Do not
overfill. Use only manufacturer’s recommended power
steering fluid.
CAUTION!
Do not use chemical flushes in your power steering
system as the chemicals can damage your power steer-
ing components. Such damage is not covered by the
New Vehicle Limited Warranty.
If necessary, add fluid to restore to the proper indicated
level. With a clean cloth, wipe any spilled fluid from all surfaces. Refer to “Fluids, Lubricants And Genuine Parts”
in “Maintaining Your Vehicle” for further information.
SPEED CONTROL
When engaged, the Speed Control takes over accelerator
operations at speeds greater than 25 mph (40 km/h) up to
the maximum speed of 100 mph (160 km/h).
The Speed Control Lever is located on the left side of the
steering column.

150 STARTING AND OPERATING

WARNING!
•Never have any smoking materials lit in or near the
vehicle when the fuel door is open or the tank is
being filled.
• Never add fuel when the engine is running. This is
in violation of most state and federal fire regulations
and may cause the “Malfunction Indicator Light” to
turn on.
• A fire may result if fuel is pumped into a portable
container that is inside of a vehicle. You could be
burned. Always place fuel containers on the ground
while filling.
CAUTION!
• Damage to the fuel system or emissions control
system could result from using an improper fuel
tank filler tube cap.
• A poorly fitting fuel filler cap could let impurities
into the fuel system.
• A poorly fitting fuel filler cap may cause the “Mal-
function Indicator Light (MIL)” to turn on.
• To avoid fuel spillage and overfilling, do not “top

CAUTION! (Continued)
off” the fuel tank after filling. When the fuel nozzle
“clicks” or shuts off, the fuel tank is full.
NOTE:
• When the fuel nozzle “clicks” or shuts off, the fuel tank
is full.
• Tighten the fuel filler cap until you hear a “clicking”
sound. This is an indication that the fuel filler cap is
properly tightened.
• If the gas cap is not tightened properly, the MIL may
come on. Be sure the gas cap is tightened every time the
vehicle is refueled.
Loose Fuel Filler Cap Message
If the vehicle diagnostic system determines that the fuel
filler cap is loose, improperly installed, or damaged, a
“Check fuel cap” message will be displayed in the instru-
ment cluster display. Refer to “Instrument Cluster Display”
in “Getting To Know Your Instrument Panel” for further
information. Tighten the fuel filler cap until a “clicking”
sound is heard. This is an indication that the fuel filler cap

2. Verify that the valve stem (on the wheel with thedeflated tire) is in a position that is near to the ground.
This will allow the Tire Service Kit Hoses (6) and (7) to
reach the valve stem and keep the Tire Service Kit flat on
the ground. This will provide the best positioning of the
kit when injecting the sealant into the deflated tire and
running the air pump. Move the vehicle as necessary to
place the valve stem in this position before proceeding.
3. Place the transmission in PARK (auto transmission) or in Gear (manual transmission) and place the ignition in the
OFF position.
4. Apply the parking brake.
(B) Setting Up To Use Tire Service Kit:
1. Push in the Mode Select Knob (5) and turn to the Sealant Mode position.
2. Uncoil the Sealant Hose (6) and then remove the cap from the fitting at the end of the hose.
3. Place the Tire Service Kit flat on the ground next to the deflated tire.
4. Remove the cap from the valve stem and then screw the fitting at the end of the Sealant Hose (6) onto the valve
stem. 5. Uncoil the Power Plug (8) and insert the plug into the
vehicle’s 12 Volt power outlet.
NOTE: Do not remove foreign objects (e.g., screws or
nails) from the tire.
(C) Injecting Tire Service Kit Sealant Into The
Deflated Tire:
• Always start the engine before turning ON the Tire
Service Kit.
NOTE: Manual transmission vehicles must have the park-
ing brake engaged and the gear selector in NEUTRAL.
• After pushing the Power Button (4), the sealant (white
fluid) will flow from the Sealant Bottle (1) through the
Sealant Hose (6) and into the tire.
NOTE: Sealant may leak out through the puncture in the
tire.
If the sealant (white fluid) does not flow within0–10
seconds through the Sealant Hose (6):
1. Push the Power Button (4) to turn Off the Tire Service Kit. Disconnect the Sealant Hose (6) from the valve stem.
Make sure the valve stem is free of debris. Reconnect the
Sealant Hose (6) to the valve stem. Check that the Mode
210 IN CASE OF EMERGENCY

Select Knob (5) is in the Sealant Mode position and not
Air Mode. Push the Power Button (4) to turn On the Tire
Service Kit.
2. Connect the Power Plug (8) to a different 12 Volt power outlet in your vehicle or another vehicle, if available.
Make sure the engine is running before turning ON the
Tire Service Kit.
3. The Sealant Bottle (1) may be empty due to previous use. Call for assistance.
NOTE: If the Mode Select Knob (5) is on Air Mode and the
pump is operating, air will dispense from the Air Pump
Hose (7) only, not the Sealant Hose (6).
If the sealant (white fluid) does flow through the Sealant
Hose (6):
1. Continue to operate the pump until sealant is no longer flowing through the hose (typically takes 30 - 70 sec-
onds). As the sealant flows through the Sealant Hose (6),
the Pressure Gauge (3) can read as high as 70 psi (4.8
Bar). The Pressure Gauge (3) will decrease quickly from
approximately 70 psi (4.8 Bar) to the actual tire pressure
when the Sealant Bottle (1) is empty. 2. The pump will start to inject air into the tire immedi-
ately after the Sealant Bottle (1) is empty. Continue to
operate the pump and inflate the tire to the pressure
indicated on the tire pressure label on the driver-side
latch pillar (recommended pressure). Check the tire
pressure by looking at the Pressure Gauge (3).
If the tire does not inflate to at least 26 psi (1.8 Bar)
pressure within 15 minutes:
• The tire is too badly damaged. Do not attempt to drive
the vehicle further. Call for assistance.
NOTE: If the tire becomes overinflated, push the Deflation
Button to reduce the tire pressure to the recommended
inflation pressure before continuing.
If the tire inflates to the recommended pressure or is at
least 26 psi (1.8 Bar) pressure within 15 minutes:
1. Push the Power Button (4) to turn off the Tire Service Kit.
2. Remove the Speed Limit sticker from the top of the Sealant Bottle (1) and place the sticker on the instrument
panel.
