The vehicle has Driver Mode
Control and may have Competitive
Driving Mode. See Driver Mode
Control on page 9-39 and
Competitive Driving Mode on
page 9-43.
Tire Pressure Monitor
This vehicle may have a Tire
Pressure Monitor System (TPMS).
The low tire pressure warning light
alerts to a significant loss in
pressure of one of the vehicle's
tires. If the warning light comes on,
stop as soon as possible and inflate
the tires to the recommended
pressure shown on the Tire and
Loading Information label. See
Vehicle Load Limits on page 9-14.
The warning light will remain on until
the tire pressure is corrected.
The low tire pressure warning light
may come on in cool weather when
the vehicle is first started, and then
turn off as the vehicle is driven. This
may be an early indicator that the
tire pressures are getting low and
the tires need to be inflated to the
proper pressure. The TPMS does not replace normal
monthly tire maintenance. Maintain
the correct tire pressures.
See
Tire Pressure Monitor System
on page 10-57.Performance Vehicle
Features
Checking Engine Oil
Your vehicle may have a high
performance dry sump lubrication
system. This system operates
differently than a standard engine
lubrication system. See Engine Oil
on page 10-12.
Check the oil level only after the
engine has been thoroughly warmed
up and then check between five and
10 minutes of shutoff. This ensures
that the oil level reading obtained
will be accurate.
Brake Noise
Under certain weather or operating
conditions, occasional brake squeal
may be heard with the vehicle's

2. Use the oval base of the keyblade to separate the two halves
of the transmitter.3. Remove the old battery. Do notuse a metal object.
4. Insert the new battery on the back housing, positive side
facing down. Replace with a
CR2032 or equivalent battery.
5. Align the key release button and snap the transmitter back
together.
Remote Vehicle Start
If equipped, this feature allows the
engine to be started from up to 60 m
(197 ft) away from the vehicle.
/(Remote Vehicle Start): This
button will be on the RKE
transmitter if the vehicle has remote
start.
The climate control system will use
the previous settings during a
remote start. The rear window
defogger may come on during
remote start based on cold ambient
conditions. The rear defog indicator
light does not come on during
remote start.
During a remote start, the heated or
ventilated seats, if equipped, may
turn on automatically. See Heated
and Ventilated Front Seats on
page 3-7.
Laws in some local communities
may restrict the use of remote
starters. For example, some laws
may require a person using remote
start to have the vehicle in view.
Check local regulations for any
requirements.
If the vehicle is low on fuel, do not
use the remote start feature. The
vehicle may run out of fuel.

The immobilization system is
disarmed when the ignition is placed
in ACC/ACCESSORY or ON/RUN/
START and a valid transmitter is
found in the vehicle.
You do not have to manually arm or
disarm the system.
The system has one or more RKE
transmitters that are matched to an
immobilizer control unit in the
vehicle. Only a correctly matched
RKE transmitter starts the vehicle.
The vehicle may not start if the RKE
transmitter is damaged.
If the engine does not start and the
security light comes on, there may
be a problem with the immobilizer
system. Press the ENGINE START/
STOP button again.
If the vehicle does not start and the
RKE transmitter appears to be
undamaged, try another RKE
transmitter. Or, place the transmitter
in the transmitter pocket. See“NO
REMOTE DETECTED” underKey
and Lock Messages on page 5-38. Check the fuse. See
Fuses on
page 10-39. If the engine still does
not start with the other transmitter,
the vehicle needs service. If the
engine does start, the first
transmitter may be faulty. See your
dealer or have a new RKE
transmitter programmed to the
vehicle.
The immobilizer system can learn
new or replacement RKE
transmitters. Up to eight RKE
transmitters can be programmed for
the vehicle. To program additional
transmitters, see “Programming
Transmitters to the Vehicle” under
Remote Keyless Entry (RKE)
System Operation on page 2-3.
Do not leave the key or device that
disarms or deactivates the
theft-deterrent system in the vehicle.Exterior Mirrors
Convex Mirrors
{Warning
A convex mirror can make things,
like other vehicles, look farther
away than they really are. If you
cut too sharply into the right lane,
you could hit a vehicle on the
right. Check the inside mirror or
glance over your shoulder before
changing lanes.
The passenger side mirror is convex
shaped. A convex mirror's surface is
curved so more can be seen from
the driver seat.

system, brake and steering
systems, etc. Even if the vehicle
appears to be drivable after a
moderate crash, there may be
concealed damage that could
make it difficult to safely operate
the vehicle.
Use caution if you should attempt
to restart the engine after a crash
has occurred.
In many crashes severe enough to
inflate the airbag, windshields are
broken by vehicle deformation.
Additional windshield breakage may
also occur from the front outboard
passenger airbag.
.Airbags are designed to inflate
only once. After an airbag
inflates, you will need some new
parts for the airbag system.
If you do not get them, the
airbag system will not be there
to help protect you in another crash. A new system will include
airbag modules and possibly
other parts. The service manual
for the vehicle covers the need
to replace other parts.
.The vehicle has a crash sensing
and diagnostic module which
records information after a
crash. See
Vehicle Data
Recording and Privacy on
page 13-14 andEvent Data
Recorders on page 13-14.
.Let only qualified technicians
work on the airbag system.
Improper service can mean that
the airbag system will not work
properly. See your dealer for
service.
Passenger Sensing
System
The vehicle has a passenger
sensing system for the front
outboard passenger position. The
passenger airbag status indicator
will light on the instrument panel
when the vehicle is started.
United States
Canada and Mexico
The words ON and OFF, or the
symbol for on and off, will be visible
during the system check. When the
system check is complete, either the
word ON or OFF, or the symbol for
on or off, will be visible. See
Passenger Airbag Status Indicator
on page 5-17.

5-6 Instruments and Controls
Warning Lights,
Gauges, and
Indicators
Warning lights and gauges can
signal that something is wrong
before it becomes serious enough
to cause an expensive repair or
replacement. Paying attention to the
warning lights and gauges could
prevent injury.
Warning lights come on when there
could be a problem with a vehicle
function. Some warning lights come
on briefly when the engine is started
to indicate they are working.Gauges can indicate when there
could be a problem with a vehicle
function. Often gauges and warning
lights work together to indicate a
problem with the vehicle.
When one of the warning lights
comes on and stays on while
driving, or when one of the gauges
shows there may be a problem,
check the section that explains what
to do. Waiting to do repairs can be
costly and even dangerous.

with the airbag system. To help
avoid injury to yourself or others,
have the vehicle serviced right
away. SeeAirbag Readiness
Light on page 5-16 for more
information, including important
safety information.
Charging System Light
The charging system light comes on
briefly when the ignition is turned
on, but the engine is not running, as
a check to show the light is working.
It should go out when the engine is
started. If the light stays on or comes on
while driving, there may be a
problem with the electrical charging
system. Have it checked by your
dealer. Driving while this light is on
could drain the battery.
When this light comes on, the Driver
Information Center (DIC) also
displays a message.
See
Battery Voltage and Charging
Messages on page 5-34.
If a short distance must be driven
with the light on, be sure to turn off
all accessories, such as the radio
and air conditioner.
Malfunction
Indicator Lamp
A computer system called OBD II
(On-Board Diagnostics-Second
Generation) monitors the operation
of the vehicle to ensure emissions
are at acceptable levels, helping to
maintain a clean environment. The
malfunction indicator lamp comes
on when the vehicle is placed in Service Only Mode, as a check to
show it is working. If it does not,
have the vehicle serviced by your
dealer. See
Ignition Positions on
page 9-19.
If the malfunction indicator lamp
comes on while the engine is
running, this indicates that there is
an OBD II problem and diagnosis
and service might be required.
Malfunctions often are indicated by
the system before any problem is
apparent. Being aware of the light
can prevent more serious damage
to the vehicle. This system also
assists the service technician in
correctly diagnosing any
malfunction.

5-20 Instruments and Controls
A few driving trips with the
adapter removed should turn off
the light.
.Check that good quality fuel is
used. Poor fuel quality causes
the engine not to run as
efficiently as designed and may
cause stalling after start-up,
stalling when the vehicle is
changed into gear, misfiring,
hesitation on acceleration,
or stumbling on acceleration.
These conditions might go away
once the engine is warmed up.
If one or more of these conditions
occurs, change the fuel brand used.
It may require at least one full tank
of the proper fuel to turn the light off.
See Fuel on page 9-53.
If none of the above have made the
light turn off, your dealer can check
the vehicle. The dealer has the
proper test equipment and
diagnostic tools to fix any
mechanical or electrical problems
that might have developed.
Emissions Inspection and
Maintenance Programs
Depending on where you live, your
vehicle may be required to
participate in an emission control
system inspection and maintenance
program. For the inspection, the
emission system test equipment will
likely connect to the vehicle's Data
Link Connector (DLC).
The DLC is under the instrument
panel near the hood release. See
your dealer if assistance is needed.
The vehicle may not pass
inspection if:
.The malfunction indicator lamp is
on with the engine running, or if
the vehicle is placed in Service
Only Mode and the malfunction indicator lamp does not come
on. See your dealer for
assistance in verifying proper
operation of the malfunction
indicator lamp.
.The OBD II (On-Board
Diagnostics) system determines
that critical emission control
systems have not been
completely diagnosed. The
vehicle would be considered not
ready for inspection. This can
happen if the 12-volt battery has
recently been replaced or run
down. The diagnostic system is
designed to evaluate critical
emission control systems during
normal driving. This can take
several days of routine driving.
If this has been done and the
vehicle still does not pass the
inspection for lack of OBD II
system readiness, your dealer
can prepare the vehicle for
inspection.
