MULTI-DISPLACEMENT SYSTEM (MDS) — 5.7L
ENGINE ONLY
This feature offers improved fuel economy by shutting
off four of the engine’s eight cylinders during light load
and cruise conditions. The system is automatic with no
driver inputs or additional driving skills required.
NOTE:The MDS system may take some time to return
to full functionality after a battery disconnect.
PARKING BRAKE
The parking brake should always be applied when the
driver is not in the vehicle.
WARNING!
Never use PARK position on an automatic transmis-
sion as a substitute for the parking brake. Always
apply the parking brake fully when parked to guard
against vehicle movement and possible injury or
damage.
When parking on a flat surface, place the shift lever in the
PARK position first and then apply the parking brake.
When parking on a hill, it is important to apply the
parking brake before placing the shift lever in PARK,
otherwise the load on the transmission locking mecha-
nism may make it difficult to move the shift lever out of
PARK. As an added precaution, turn the front wheels
toward the curb on a downhill grade and away from the
curb on an uphill grade.

ELECTRONIC BRAKE CONTROL SYSTEM
Your vehicle is equipped with an advanced electronic
brake control system that include ABS (Anti-Lock Brake
System), TCS (Traction Control System), BAS (Brake
Assist System), and ESP (Electronic Stability Program).
All four of these systems work together to enhance
vehicle stability and control in various driving condi-
tions.
Anti-Lock Brake System (ABS)
This system aids the driver in maintaining vehicle control
under adverse braking conditions by controlling hydrau-
lic brake pressure. This prevents wheel lock-up to help
avoid skidding on slippery surfaces during braking.
Refer to “Anti-Lock Brake System” in Section 5 of this
manual.
WARNING!
The ABS cannot prevent the natural laws of physics
from acting on the vehicle, nor can it increase the
traction afforded by prevailing road conditions. The
ABS cannot prevent accidents, including those re-
sulting from excessive speed in turns, driving on
very slippery surfaces, or hydroplaning. Only a safe,
attentive, and skillful driver can prevent accidents.
The capabilities of an ABS-equipped vehicle must
never be exploited in a reckless or dangerous manner
that could jeopardize the user’s safety or the safety of
others.
Traction Control System (TCS)
This system monitors the amount of wheel spin of each
driven wheel. If wheel spin is detected, brake pressure is
applied to the slipping wheel(s) and engine power is
reduced to provide enhanced acceleration and stability.

loading may be required for high-speed vehicle opera-
tion. Refer to original equipment or an authorized tire
dealer for recommended safe operating speeds, loading
and cold tire inflation pressures.
WARNING!
High speed driving with your vehicle under maxi-
mum load is dangerous. The added strain on your
tires could cause them to fail. You could have a
serious accident. Do not drive a vehicle loaded to the
maximum capacity at continuous speeds above
75 mph (120 km/h).
Radial Ply Tires
WARNING!
Combining radial ply tires with other types of tires
on your vehicle will cause your vehicle to handle
poorly. The instability could cause an accident. Al-
ways use radial ply tires in sets of four (or six, in case
of trucks with dual rear wheels). Never combine
them with other types of tires.
Cuts and punctures in radial tires are repairable only in
the tread area because of sidewall flexing. Consult your
authorized tire dealer for radial tire repairs.
360 STARTING AND OPERATING
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.
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 pressure
gauge, even if under-inflation has not reached the
level to trigger illumination of the TPM Telltale Light.
•Seasonal temperature changes will affect tire pressure,
and the TPMS will monitor the actual tire pressure in
the tire.
Base System
The Tire Pressure Monitor System (TPMS) uses wireless
technology with wheel rim mounted electronic sensors to
monitor tire pressure levels. 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 monthly
and to maintain the proper pressure.
The TPMS consists of the following components:
•Receiver module,
•Four TPM sensors, and
•TPM Telltale Light
STARTING AND OPERATING 371
5
The matching full size spare wheel and tire assembly (if
equipped) has a TPM sensor. The matching full size spare
can be used in place of any of the four road tires. The
TPMS will only monitor the pressure in the full size spare
when it is used in place of a road tire. Otherwise, a spare
with a pressure below the low-pressure limit will not
cause the TPM Telltale Light to illuminate or the chime to
sound.
Tire Pressure Monitoring Low Pressure Warnings
The TPM Telltale Light will illuminate in the
instrument cluster and a chime will sound when
tire pressure is low in one or more of the four
active road tires. 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. Once the
system receives the updated tire pressures, the system
will automatically update and the TPM Telltale Light willturn off. The vehicle may need to be driven for up to
20 minutes above 15 mph (25 km/h) in order for the
TPMS to receive this information.
Check TPMS Warning
If a system fault is detected, the TPM Telltale Light will
flash on and off for 75 seconds and then remain on solid.
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 TPM Telltale Light will turn
off when the fault condition no longer exists. A system
fault can occur due to any of the following:
1. Signal interference due to electronic devices or driving
next to facilities emitting the same radio frequencies as
the TPM sensors.
2. Installing aftermarket window tinting that contains
materials that may block radio wave signals.
372 STARTING AND OPERATING
5. Once you repair or replace the original road tire, and
reinstall it on the vehicle in place of the compact spare,
the TPMS will update automatically and the TPM 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 (25 km/h) in order for the
TPMS to receive this information.
Premium System — If Equipped
The Tire Pressure Monitor System (TPMS) uses wireless
technology with wheel rim mounted electronic sensors to
monitor tire pressure levels. 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 monthly
and to maintain the proper pressure.The TPMS consists of the following components:
•Receiver module,
•Four TPM sensors,
•Various TPMS messages, which display in the Elec-
tronic Vehicle Information Center (EVIC), and
•TPM Telltale Light
The matching full size spare wheel and tire assembly (if
equipped) has a TPM sensor. The full size spare can be
used in place of any of the four road tires. A spare with a
pressure below the low-pressure limit will not cause the
TPM Telltale Light to illuminate or the chime to sound.
