WARNING!
•A loose head restraint thrown forward in a colli-
sion or hard stop could cause serious injury or
death to occupants of the vehicle. Always securely
stow removed head restraints in a location outside
the occupant compartment.
• ALL the head restraints MUST be reinstalled in the
vehicle to properly protect the occupants. Follow
the re-installation instructions above prior to oper-
ating the vehicle or occupying a seat.
NOTE: Do not reposition the head restraint 180 degrees
to the incorrect position in an attempt to gain additional
clearance to the back of the head.
Rear Head Restraints — 2 Door Model
The rear seat head restraints are not adjustable. They can
be removed to make it easier to take out the rear seat. To
remove the head restraint, push the button on each of the two head restraint guides and pull upward on the head
restraint. Replace the head restraint before driving the
vehicle with passengers in the rear seat. To replace the
head restraint, insert the head restraint rods into the
guides and push downward on the head restraint until
locked. Refer to “Occupant Restraints” in “Things to
Know Before Starting Your Vehicle” for information on
child seat tether routing.

WARNING!(Continued)
locked in PARK, securing the vehicle against un-
wanted movement.
• When leaving the vehicle, always remove the igni-
tion 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 transmission 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.
Key Ignition Park Interlock
This vehicle is equipped with a Key Ignition Park Inter-
lock which requires the transmission to be in PARK
before the ignition switch can be turned to the LOCK/
OFF (key removal) position. The key can only be re-
moved from the ignition when the ignition is in the
LOCK/OFF position, and once removed the transmission
is locked in PARK.
NOTE: If a malfunction occurs, the system will trap the
key in the ignition switch to warn you that this safety
feature is inoperable. The engine can be started and
stopped but the key cannot be removed until you obtain
service.
Brake/Transmission Shift Interlock System
This vehicle is equipped with a Brake Transmission Shift
Interlock System (BTSI) that holds the shift lever in PARK
unless the brakes are applied. To shift the transmission

WARNING!
The Brake Assist System (BAS) cannot prevent the
natural laws of physics from acting on the vehicle,
nor can it increase the traction afforded by prevailing
road conditions. The BAS cannot prevent collisions,
including those resulting from excessive speed in
turns, driving on very slippery surfaces, or hydro-
planing. The capabilities of a BAS-equipped vehicle
must never be exploited in a reckless or dangerous
manner which could jeopardize the user’s safety or
the safety of others.
Hill Start Assist (HSA)
The HSA system is designed to assist the driver when
starting a vehicle from a stop on a hill. HSA will maintain
the level of brake pressure the driver applied for a short
period of time after the driver takes their foot off of the
brake pedal. If the driver does not apply the throttleduring this short period of time, the system will release
brake pressure and the vehicle will roll down the hill. The
system will release brake pressure in proportion to
amount of throttle applied as the vehicle starts to move in
the intended direction of travel.

•Each time the ignition is cycled to the ON/RUN
position, the ESC system will be ON even if it was
cycled off previously, except for when the vehicle is
started while in 4L Range.
• The ESC system will make buzzing or clicking sounds
when it is active. This is normal; the sounds will stop
when ESC becomes inactive following the maneuver
that caused the ESC activation.
The “ESC OFF Indicator Light” indicates the
Electronic Stability Control (ESC) is partially
off or full off.
Trailer Sway Control (TSC)
TSC uses sensors in the vehicle to recognize an excessively
swaying trailer and will take the appropriate actions to
attempt to stop the sway. The system may reduce engine
power and apply the brake of the appropriate wheel(s) to counteract the sway of the trailer. TSC will become active
automatically once an excessively swaying trailer is recog-
nized. TSC cannot stop all trailers from swaying. Always
use caution when towing a trailer and follow the tongue
weight recommendations. Refer to “Trailer Towing” in
“Starting and Operating” for further information. When
TSC is functioning, the “ESC Activation/Malfunction Indi-
cator Light” will flash, the engine power may be reduced
and you may feel the brakes being applied to individual
wheels to attempt to stop the trailer from swaying. TSC is
disabled when the ESC system is in the
ESC Partial Offor
ESC Full Off modes.

Under normal operating conditions, the catalytic converter
will not require maintenance. However, it is important to
keep the engine properly tuned to assure proper catalyst
operation and prevent possible catalyst damage.
NOTE:Intentional tampering with emissions control
systems can result in civil penalties being assessed
against you.
In unusual situations involving grossly malfunctioning
engine operation, a scorching odor may suggest severe
and abnormal catalyst overheating. If this occurs, stop
the vehicle, turn off the engine and allow it to cool.
Service, including a tune-up to manufacturer’s specifica-
tions, should be obtained immediately.
To minimize the possibility of catalytic converter dam-
age:
• Do not shut off the engine or interrupt the ignition,
when the transmission is in gear and the vehicle is in
motion. •
Do not try to start the engine by pushing or towing the
vehicle.
• Do not idle the engine with any spark plug wires
disconnected or removed, such as when diagnostic
testing, or for prolonged periods during very rough
idle or malfunctioning operating conditions.
