7. Press the “ESC Off” switch (located in the lowerswitch bank below the climate controls) four times
within 20 seconds. The “ESC Activation/Malfunction
Indicator Light” should turn on and turn off two
times.
8. Rotate the steering wheel back to center and then an additional half-turn to the right.
9. Turn the ignition switch to the OFF position and then back to the ON position. If the sequence was com-
pleted properly, the “ESC Activation/Malfunction In-
dicator Light” will blink several times to confirm HSA
is disabled.
10. Repeat these steps if you want to return this feature to it’s previous setting.Electronic Stability Control (ESC)
This system enhances directional control and stability of
the vehicle under various driving conditions. ESC cor-
rects for over-steering or under-steering of the vehicle by
applying the brake of the appropriate wheel to assist in
counteracting the over-steering or under-steering condi-
tion. Engine power may also be reduced to help the
vehicle maintain the desired path. ESC uses sensors in
the vehicle to determine the vehicle path intended by the
driver and compares it to the actual path of the vehicle.
When the actual path does not match the intended path,
ESC applies the brake of the appropriate wheel to assist
in counteracting the over-steer or under-steer condition
•Over-steer - when the vehicle is turning more than
appropriate for the steering wheel position.
• Under-steer - when the vehicle is turning less than
appropriate for the steering wheel position.

CAUTION!
•The TPMS has been optimized for the original
equipment tires and wheels. TPMS pressures and
warning have been established for the tire size
equipped on your vehicle. Undesirable system op-
eration or sensor damage may result when using
replacement equipment that is not of the same size,
type, and/or style. Aftermarket wheels can cause
sensor damage. Using aftermarket tire sealants may
cause the Tire Pressure Monitoring System (TPMS)
sensor to become inoperable. After using an after-
market tire sealant it is recommended that you take
your vehicle to an authorized dealership to have
your sensor function checked.
(Continued)
CAUTION! (Continued)
•After inspecting or adjusting the tire pressure,
always reinstall the valve stem cap. This will
prevent moisture and dirt from entering the valve
stem, which could damage the Tire Pressure Moni-
toring Sensor.
NOTE:
• The TPMS is not intended to replace normal tire care
and maintenance or to provide warning of a tire failure
or condition.
• The TPMS should not be used as a tire pressure gauge
while adjusting your tire pressure.
• Driving on a significantly under-inflated tire causes
the tire to overheat and can lead to tire failure.
406 STARTING AND OPERATING

Under-inflation also reduces fuel efficiency and tire
tread life, and may affect the vehicle’s handling and
stopping ability.
• The TPMS is not a substitute for proper tire mainte-
nance, and it is the driver ’s responsibility to maintain
correct tire pressure using an accurate tire gauge, even
if under-inflation has not reached the level to trigger
illumination of the Tire Pressure Monitoring Telltale
Light.
• Seasonal temperature changes will affect tire pressure,
and the TPMS will monitor the actual tire pressure in
the tire.
Base System
This is the TPMS warning indicator located in the
instrument cluster. The TPMS uses wireless technology with wheel rim
mounted electronic sensors to monitor tire pressure lev-
els. Sensors, mounted to each wheel as part of the valve
stem, transmit tire pressure readings to the Receiver
Module.
NOTE:
It is particularly important for you to check the
tire pressure in all of the tires on your vehicle regularly
and to maintain the proper pressure.
The TPMS consists of the following components:
• Receiver Module.
• Four Tire Pressure Monitoring Sensors.
• Tire Pressure Monitoring Telltale Light.
Tire Pressure Monitoring Low Pressure Warnings
The Tire Pressure Monitoring Telltale Light will illumi-
nate in the instrument cluster, a LOW TIRE message will
be displayed for a minimum of five seconds, and an
5
STARTING AND OPERATING 407

audible chime will be activated when one or more of the
four active road tire pressures are low. Should this occur,
you should stop as soon as possible, check the inflation
pressure of each tire on your vehicle, and inflate each tire
to the vehicle’s recommended cold placard pressure
value. The system will automatically update and the Tire
Pressure Monitoring Light will extinguish and the LOW
TIRE message will turn off once the updated tire pres-
sures have been received. The vehicle may need to be
driven for up to 20 minutes above 15 mph (24 km/h) to
receive this information.
Check TPMS Warnings
The Tire Pressure Monitoring Telltale Light will flash on
and off for 75 seconds and remain on solid when a system
fault is detected. The system fault will also sound a
chime. If the ignition key is cycled, this sequence will
repeat providing the system fault still exists. The TirePressure Monitoring Telltale Light will turn off when the
fault condition no longer exists. A system fault can occur
with any of the following scenarios:
1. Jamming due to electronic devices or driving next to
facilities emitting the same radio frequencies as the
TPM sensors.
2. Installing some form of aftermarket window tinting that affects radio wave signals.
3. Snow or ice around the wheels or wheel housings.
4. Using tire chains on the vehicle.
5. Using wheels/tires not equipped with TPM sensors.
NOTE: Your vehicle is equipped with a compact spare
wheel and tire assembly.
1. The compact spare tire does not have a tire pressure monitoring sensor. Therefore, the TPMS will not moni-
tor the tire pressure in the compact spare tire.
408 STARTING AND OPERATING

2. If you install the compact spare tire in place of a roadtire that has a pressure below the low-pressure warn-
ing limit, upon the next ignition key cycle, a chime will
sound and the Tire Pressure Monitoring Telltale Light
and LOW TIRE message will still turn ON due to the
low tire.
3. However, after driving the vehicle for up to 20 min- utes above 15 mph (24 km/h), the Tire Pressure
Monitoring Telltale Light will flash on and off for 75
seconds and then remain on solid.
4. For each subsequent ignition key cycle, a chime will sound and the Tire Pressure Monitoring Telltale Light
will flash on and off for 75 seconds and then remain on
solid.
5. Once you repair or replace the original road tire and reinstall it on the vehicle in place of the compact spare
tire, the TPMS will update automatically and the Tire
Pressure Monitoring Telltale Light will turn OFF, as long as no tire pressure is below the low-pressure
warning limit in any of the four active road tires. The
vehicle may need to be driven for up to 20 minutes
above 15 mph (24 km/h) in order for the TPMS to
receive this information.
Premium System — If Equipped
The TPMS uses wireless technology with wheel rim
mounted electronic sensors to monitor tire pressure lev-
els. Sensors, mounted to each wheel as part of the valve
stem, transmit tire pressure readings to the receiver
module.
NOTE:
It is particularly important for you to check the
tire pressure in all of your tires regularly and to maintain
the proper pressure.
The TPMS consists of the following components:
• Receiver Module
• Four Tire Pressure Monitoring Sensors
5
STARTING AND OPERATING 409

the graphic display of the pressure value(s) will stop
flashing, and the Tire Pressure Monitoring Light will
extinguish once the updated tire pressure(s) have been
received. The vehicle may need to be driven for up to 20
minutes above 15 mph (24 km/h) to receive this infor-
mation.
Service TPMS Message
The Tire Pressure Monitoring Telltale Light will flash on
and off for 75 seconds, and remain on solid when a
system fault is detected. The system fault will also sound
a chime. The EVIC will display a “SERVICE TPM SYS-
TEM” message for a minimum of five seconds. This text
message is then followed by a graphic display, with “- -“
in place of the pressure value(s) indicating which Tire
Pressure Monitoring Sensor(s) is not being received.If the ignition key is cycled, this sequence will repeat,
providing the system fault still exists. If the system fault
no longer exists, the Tire Pressure Monitoring Telltale
Light will no longer flash, the
SERVICE TPM SYSTEM
text message will not be present, and a pressure value

will be displayed instead of dashes. A system fault can
occur with any of the following scenarios:
1. Jamming due to electronic devices or driving next tofacilities emitting the same radio frequencies as the
TPM sensors.
2. Installing some form of aftermarket window tinting that affects radio wave signals.
3. Snow or ice around the wheels or wheel housings.
4. Using tire chains on the vehicle.
5. Using wheels/tires not equipped with TPM sensors.
The EVIC will also display a SERVICE TPM SYSTEM
message for a minimum of five seconds when a system
fault related to an incorrect sensor location fault is
detected. In this case, the SERVICE TPM SYSTEM
message is then followed with a graphic display with pressure values still shown. This indicates that the pres-
sure values are still being received from the TPM sensors
but they may not be located in the correct vehicle
position. The system still needs to be serviced as long as
the
SERVICE TPM SYSTEM message is displayed.
NOTE: Your vehicle is equipped with a compact spare
wheel and tire assembly.
1. The compact spare tire does not have a tire pressure monitoring sensor. Therefore, the TPMS will not moni-
tor the tire pressure in the compact spare tire.
2. If you install the compact spare tire in place of a road tire that has a pressure below the low-pressure warn-
ing limit, upon the next ignition key cycle, a chime will
sound and the Tire Pressure Monitoring Telltale Light
will still turn ON due to the low tire. The “LOW TIRE”
text message and the graphic with the low tire pres-
sure flashing will be displayed.

FUEL REQUIREMENTS
2.0L And 2.4L Engine
This engine is designed to meet all emis-
sions regulations and provide excellent
fuel economy and performance when us-
ing high-quality unleaded “regular” gaso-
line having an octane rating of 87. The use
of premium gasoline will not provide any benefit over
regular gasoline in these engines.
Light spark knock at low engine speeds is not harmful to
your engine. However, continued heavy spark knock at high speeds can cause damage and immediate service is
required. Poor quality gasoline can cause problems such
as hard starting, stalling, and hesitations. If you experi-
ence these symptoms, try another brand of gasoline
before considering service for the vehicle.
Over 40 auto manufacturers worldwide have issued and
endorsed consistent gasoline specifications (the World-
wide Fuel Charter, WWFC) which define fuel properties
necessary to deliver enhanced emissions, performance,
and durability for your vehicle. The manufacturer recom-
mends the use of gasolines that meet the WWFC speci-
fications if they are available.
Reformulated Gasoline
Many areas of the country require the use of cleaner
burning gasoline referred to as “Reformulated Gasoline.”
Reformulated gasoline contain oxygenates and are spe-
cifically blended to reduce vehicle emissions and im-
prove air quality.
