immobilizer system. Modifications or alterations to
the immobilization system may result in a loss of
security protection.
•The Sentry Key® Immobilizer system is not com-
patible with some aftermarket remote starting sys-
tems. Use of these systems may result in vehicle
starting problems and loss of security protection.
All of the Key Fobs provided with your new vehicle have
been programmed to the vehicle electronics.
Replacement Keys
NOTE:Only Key Fobs that are programmed to the
vehicle electronics can be used to start and operate the
vehicle. Once a Key Fob is programmed to a vehicle, it
cannot be programmed to any other vehicle.
CAUTION!
•Always remove the Key Fobs from the vehicle and
lock all doors when leaving the vehicle unat-
tended.
•For vehicles equipped with Keyless Enter-N-Go™,

THINGS TO KNOW BEFORE STARTING YOUR VEHICLE 17

At the time of purchase, the original owner is provided
with a four-digit Personal Identification Number (PIN).
Keep the PIN in a secure location. This number is
required for authorized dealer replacement of Key Fobs.
Duplication of Key Fobs may be performed at an autho-
rized dealer. This procedure consists of programming a
blank Key Fob to the vehicle electronics. A blank Key Fob
is one that has never been programmed.
NOTE:When having the Sentry Key® Immobilizer Sys-
tem serviced, bring all vehicle keys with you to an
authorized dealer.
Customer Key Programming
Programming Key Fobs or RKE transmitters may be
performed at an authorized dealer.

General Information
This vehicle has systems that operate on radio frequency
that comply with Part 15 of the Federal Communications
Commission (FCC) rules and with Industry Canada
Standards RSS- GEN/210/220/310.
Operation is subject to the following two conditions:
1. The device may not cause harmful interference.
2. The device must accept any interference received,
including interference that may cause undesired op-
eration of the device.
Changes or modifications to any of these systems by
other than an authorized service facility could void
authorization to use this equipment.
Normal (Fixed Speed) Electronic Speed Control
Mode
In addition to Adaptive Cruise Control mode, a Normal
(Fixed Speed) Electronic Speed Control mode is available
for cruising at fixed speeds. The Normal (Fixed Speed)
Electronic Speed Control mode is designed to maintain a
set cruising speed without requiring the driver to operate
the accelerator. Electronic Speed Control can only be
operated if the vehicle speed is above 20 mph (32 km/h).
To change between the different control modes, press the
ADAPTIVE CRUISE CONTROL (ACC) ON/OFF button
which turns the ACC and the NORMAL (Fixed Speed)
ELECTRONIC SPEED CONTROL OFF. Pressing of the
NORMAL (Fixed Speed) ELECTRONIC SPEED CON-
TROL ON/OFF button will result in turning ON (chang-
ing to) the Normal (Fixed Speed) Electronic Speed Con-
trol mode.

CAUTION!
Driving with a hot engine cooling system could
damage your vehicle. If the temperature gauge reads
“H” pull over and stop the vehicle. Idle the vehicle
with the air conditioner turned off until the pointer
drops back into the normal range. If the pointer
remains on the “H” and you hear continuous chimes,
turn the engine off immediately and call an autho-
rized dealer for service.
WARNING!
A hot engine cooling system is dangerous. You or
others could be badly burned by steam or boiling
coolant. You may want to call an authorized dealer
for service if your vehicle overheats. If you decide to
look under the hood yourself, see “Maintaining Your
(Continued)
WARNING!(Continued)
Vehicle”. Follow the warnings under the Cooling
System Pressure Cap paragraph.
12. Brake Warning Light
This light monitors various brake functions,
including brake fluid level and parking brake
application. If the brake light turns on it may
indicate that the parking brake is applied, that
the brake fluid level is low, or that there is a problem with
the anti-lock brake system reservoir.
If the light remains on when the parking brake has been
disengaged, and the fluid level is at the full mark on the
master cylinder reservoir, it indicates a possible brake
hydraulic system malfunction or that a problem with the
Brake Booster has been detected by the Anti-Lock Brake
System (ABS) / Electronic Stability Control (ESC) system.
In this case, the light will remain on until the condition

UNDERSTANDING YOUR INSTRUMENT PANEL 295

has been corrected. If the problem is related to the brake
booster, the ABS pump will run when applying the brake
and a brake pedal pulsation may be felt during each stop.
The dual brake system provides a reserve braking capac-
ity in the event of a failure to a portion of the hydraulic
system. A leak in either half of the dual brake system is
indicated by the Brake Warning Light, which will turn on
when the brake fluid level in the master cylinder has
dropped below a specified level.
The light will remain on until the cause is corrected.
NOTE:The light may flash momentarily during sharp
cornering maneuvers, which change fluid level condi-
tions. The vehicle should have service performed, and
the brake fluid level checked.
If brake failure is indicated, immediate repair is neces-
sary.
WARNING!
Driving a vehicle with the red brake light on is
dangerous. Part of the brake system may have failed.
It will take longer to stop the vehicle. You could have
a collision. Have the vehicle checked immediately.
Vehicles equipped with the Anti-Lock Brake System
(ABS), are also equipped with Electronic Brake Force
Distribution (EBD). In the event of an EBD failure, the
Brake Warning Light will turn on along with the ABS
Light. Immediate repair to the ABS system is required.
Operation of the Brake Warning Light can be checked by
turning the ignition switch from the OFF position to the
ON/RUN position. The light should illuminate for ap-
proximately two seconds. The light should then turn off
unless the parking brake is applied or a brake fault is
detected. If the light does not illuminate, have the light
inspected by an authorized dealer.

vehicle is experiencing a problem with the charging
system. Obtain SERVICE IMMEDIATELY. See an autho-
rized dealer.
If jump starting is required, refer to “Jump Starting
Procedures” in “What To Do In Emergencies”.
•Electronic Throttle Control (ETC) Light
This light informs you of a problem with the
Electronic Throttle Control (ETC) system. The
light will come on when the ignition is first
turned ON and remain on briefly as a bulb
check. If the light does not come on during starting, have
the system checked by an authorized dealer.
If a problem is detected, the light will come on while the
engine is running. Cycle the ignition key when the
vehicle has completely stopped and the shift lever is
placed in the PARK position. The light should turn off.
If the light remains lit with the engine running, your
vehicle will usually be drivable. However, see an autho-
rized dealer for service as soon as possible. If the light is
flashing when the engine is running, immediate service is
