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

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

• 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.

The conditions under which AutoPark will engage are
outlined on the following pages.
WARNING!
•Driver inattention could lead to failure to place the
vehicle in PARK. ALWAYS DO A VISUAL CHECK
that your vehicle is in PARK by verifying that a solid
(not blinking) “P” is indicated in the Instrument
Cluster Display and near the gear selector. If the P
indicator is blinking, your vehicle is not in PARK. As
an added precaution, always apply the parking brake
when exiting the vehicle.
• AutoPark is a supplemental feature. It is not de-
signed to replace the need to shift your vehicle into
PARK. It is a back up system and should not be
relied upon as the primary method by which the
driver shifts the vehicle into PARK.
If the vehicle is not in PARK and the driver turns off the
engine, the vehicle may AutoPark.
AutoPark will engage when all of these conditions are met:
• Vehicle is equipped with a rotary shifter and an 8-speed
transmission

296 STARTING AND OPERATING

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
Electric Park Brake (EPB)
Your vehicle is equipped with an Electric Park Brake
System (EPB) that offers simple operation, and some
additional features that make the parking brake more
convenient and useful.
The parking brake is primarily intended to prevent the
vehicle from rolling while parked. Before leaving the
vehicle, make sure that the park brake is applied. Also, be
certain to leave the transmission in PARK.
You can engage the park brake in two ways:
• Manually, by applying the park brake switch.
• Automatically, by enabling the Auto Park Brake feature
in the customer programmable features section of the
Uconnect settings. The park brake switch is located on the instrument panel to
the left of the steering wheel (below the headlamp switch).
To apply the park brake manually, pull up on the switch
momentarily. You may hear a slight whirring sound from
the back of the vehicle while the park brake engages. Once
the park brake is fully engaged, the BRAKE telltale light in
the instrument cluster and an indicator on the switch will
illuminate. If your foot is on the brake pedal while you
apply the park brake, you may notice a small amount of
brake pedal movement. The park brake can be applied
even when the ignition switch is OFF but the BRAKE

motor vehicle. Do only that service work for which you
have the knowledge and the right equipment. If you
have any doubt about your ability to perform a service
job, take your vehicle to a competent mechanic.
AUTOMATIC TRANSMISSION
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
transmission gear selector out of PARK with the
brake pedal released. Make sure the transmission is
in PARK before exiting the vehicle.
• The transmission may not engage PARK if the ve-
hicle is moving. Always bring the vehicle to a
complete stop before shifting to PARK, and verify
that the transmission gear position indicator solidly
indicates PARK (P) without blinking. Ensure that the
vehicle is completely stopped, and the PARK posi-
tion is properly indicated, 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
