WARNING!
• ONLY use the driver’s side floor mat on
the driver’s side floor area. To check for
interference, with the 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 accelerator,
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 ob-
jects could change the position of the
floor mat and may cause interference
WARNING!
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 interference with the accelera-
tor, 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 se-
cured 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 thetread or sidewall. Inspect the tread for cuts
and cracks. Inspect sidewalls for cuts,
cracks, and bulges. Check the wheel nuts for
tightness. Check the tires (including 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.
Door Latches
Check for proper closing, latching, and lock-
ing.
Fluid Leaks
Check area under the vehicle after overnight
parking for fuel, coolant, oil, or other fluid
leaks. Also, if gasoline fumes are detected or
if fuel, or brake fluid leaks are suspected. The
cause should be located and corrected imme-
diately.

WARNING!
• Do not leave children or animals inside
parked vehicles in hot weather. Interior
heat build-up may cause serious injury
or death.
NOTE:
Engine start up in very low ambient tempera-
ture could result in evident white smoke. This
condition will disappear as the engine warms
up.
CAUTION!
The engine is allowed to crank as long as
30 seconds. If the engine fails to start
during this period, please wait at least two
minutes for the starter to cool before re-
peating start procedure.
Normal Starting Procedure — Keyless
Enter-N-Go

Normal starting of either a cold or a warm
engine is obtained without pumping or press-
ing the accelerator pedal.
1. Always apply the parking brake.
2. Press and hold the brake pedal while
pushing the ENGINE START/STOP button
once.
NOTE:
A delay of the start of up to five seconds is
possible under very cold conditions. The
“Wait to Start” telltale will be illuminated

engine Wait To Start light goes off the
engine will automatically crank.
CAUTION!
If the “Water in Fuel Indicator Light” re-
mains on, DO NOT START the engine be-
fore the water is drained from the fuel
filters to avoid engine damage.
3. The system will automatically engage the

Parking
When parking and leaving the vehicle, pro-
ceed as follows:
• Engage a gear (first gear if facing uphill or
reverse if facing downhill) and leave the
wheels turned.
• Stop the engine and engage the park brake.
• Always remove the key fob.
• Block the wheels with a wedge or a stone if
the vehicle is parked on a steep slope.
NOTE:
NEVER leave the car with the gearbox in
neutral (or, if equipped with automatic trans-
mission, before placing the gear lever in
PARK).
WARNING!
Never leave children unattended in the
vehicle. Always remove the key fob when
exiting the vehicle and take it with you.
AUTOMATIC
TRANSMISSION — IF
EQUIPPED
WARNING!
• Never use the PARK position as a sub-
stitute for the park brake. Always apply
the park brake fully when exiting the
vehicle to guard against vehicle move-
ment 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 exiting 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
reverse. You could lose control of the
vehicle and hit someone or something.
Only shift into gear when the engine is
WARNING!
idling normally and your foot is firmly
pressing the brake pedal.
• The vehicle may not engage a newly
selected gear if the vehicle is moving
while shifting.
• 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 run-
ning. Before exiting a vehicle always
come to a complete stop, then apply the
park brake, shift the transmission into
PARK, turn the engine OFF, and remove
the key fob. When the ignition is in the
LOCK/OFF (key removal) position (or,
with push button start, when the ignition
is in the OFF mode), the transmission is
locked in PARK, securing the vehicle
against unwanted movement.
• When leaving the vehicle, always make
sure the ignition is in the OFF mode,
remove the key fob from the vehicle, and
lock the vehicle.
• Never leave children alone in a vehicle,
or with access to an unlocked vehicle.

Gear Ranges
Do not depress the accelerator pedal when
shifting from PARK or NEUTRAL into another
gear range.
NOTE:
After selecting any gear range, wait a moment
to allow the selected gear to engage before
accelerating. This is especially important
when the engine is cold.PARK (P)
This range supplements the parking brake by
locking the transmission. The engine can be
started in this range. Never attempt to use
PARK while the vehicle is in motion. Apply
the parking brake when exiting the vehicle in
this range.
When parking on a level surface, you may
shift the transmission into PARK first, and
then apply the parking brake.
When parking on a hill, apply the parking
brake before shifting the transmission to
PARK, otherwise the load on the transmission
locking mechanism may make it difficult to
move the gear selector out of PARK. As an
added precaution, turn the front wheels to-
ward the curb on a downhill grade and away
from the curb on an uphill grade.
When exiting the vehicle, always:
1. Apply the parking brake.
2. Shift the transmission into PARK.
3. Turn the ignition OFF.
4. Remove the key fob from the vehicle.NOTE:
Block the wheels with a wedge or a stone if
the vehicle is parked on a steep slope.
WARNING!
• Never use the PARK position as a sub-
stitute for the park brake. Always apply
the park brake fully when exiting the
vehicle to guard against vehicle move-
ment 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 exiting the vehicle.
