Vehicle Modification Data Recording
Some aftermarket products may cause severe engine and/or transmission
damage; refer to the What is not covered section in The new vehicle
limited warranty for your vehicle chapter of your vehicle’s Warranty
Guide for more information. Some vehicles are equipped with
Powertrain Control Systems that can detect and store information about
vehicle modifications that increase horsepower and torque output; this
information cannot be erased and will stay in the system’s memory even
if the modification is removed. When a dealer or repair facility works on
your vehicle, it may be necessary for them to access the information in
the Powertrain Control System. This information will likely identify if any
unauthorized modifications have been made to the system and may be
used to determine if repairs will be covered by warranty.
Special instructions
For your added safety, your vehicle is fitted with sophisticated electronic
controls.
Please read the section Supplemental restraint system (SRS)
in the Seating and Safety Restraints chapter. Failure to follow
the specific warnings and instructions could result in personal injury.
Front seat mounted rear-facing child or infant seats should
NEVER be placed in front of an active passenger airbag.
Cell phone use
The use of Mobile Communications Equipment has become increasingly
important in the conduct of business and personal affairs. However,
drivers must not compromise their own or others’ safety when using
such equipment. Mobile Communications can enhance personal safety
and security when appropriately used, particularly in emergency
situations. Safety must be paramount when using mobile communications
equipment to avoid negating these benefits.
Mobile Communication Equipment includes, but is not limited to cellular
phones, pagers, portable email devices, in-vehicle communications
systems, telematics devices and portable two-way radios.
A driver’s first responsibility is the safe operation of the vehicle.
The most important thing you can do to prevent a crash is to
avoid distractions and pay attention to the road. Wait until it is safe to
operate Mobile Communications Equipment.

Driving a vehicle with the brake system warning light on is
dangerous. A significant decrease in braking performance may
occur. It will take you longer to stop the vehicle. Have the vehicle
checked by your authorized dealer immediately.
Anti-lock brake system: If the
ABS light stays illuminated or
continues to flash, a malfunction has
been detected, have the system
serviced immediately. Normal
braking is still functional unless the brake warning light also is
illuminated.
Airbag readiness: If this light fails
to illuminate when ignition is turned
to ON, continues to flash or remains
on, have the system serviced
immediately. A chime will also sound when a malfunction in the
supplemental restraint system has been detected.
Safety belt: Reminds you to fasten
your safety belt. A chime will also
sound to remind you to fasten your
safety belt.
Charging system: Illuminates when
the battery is not charging properly.
Transmission Tow/Haul Feature
(automatic transmission):
Illuminates when the Tow/Haul
feature has been activated. Refer to
the Driving chapter for transmission function and operation. If the light
flashes steadily, have the system serviced immediately, damage to the
transmission could occur.
Four wheel drive low: Illuminates
when four-wheel drive low is
engaged.
Four wheel drive indicator:
Illuminates when four-wheel drive is
engaged. ABS

Amarillo instrument cluster
Engine oil pressure gauge:
Indicates engine oil pressure. The
needle should stay in the normal
operating range (between “L” and
“H”). If the needle falls below the
normal range, stop the vehicle, turn
off the engine and check the engine
oil level. Add oil if needed. If the oil
level is correct, have your vehicle checked at your authorized dealer.
Fuel gauge: Indicates
approximately how much fuel is left
in the fuel tank (when the ignition
is in the ON position). The fuel
gauge may vary slightly when the
vehicle is in motion or on a grade.
Refer to Filling the tank in the
Maintenance and Specifications
chapter for more information.
Battery voltage gauge (manual
transmission only): Indicates the
battery voltage when the ignition is
in the ON position. If the pointer
moves and stays outside the normal
operating range, have the vehicle’s
electrical system checked as soon as
possible.

Transmission fluid temperature gauge (automatic transmission
only): If the gauge is in the:
Normal area (normal) - the
transmission fluid is within the
normal operating temperature
(between “H” and “C”).
Yellow area (warning) — the
transmission fluid is higher than
normal operating temperature. This
can be caused by special operation
conditions (i.e. snowplowing, towing
or off road use). Refer to Special
Operating Conditions in the
scheduled maintenance
information for instructions. Operating the transmission for extended
periods of time with the gauge in the yellow area may cause internal
transmission damage.
Altering the severity of the driving conditions is recommended to lower
the transmission temperature into the normal range.
Red area (over temperature) —
the transmission fluid is overheating.
Stop the vehicle to allow the
temperature to return to normal
range.
If the gauge is operating in the Yellow or Red area, stop the vehicle and
verify the airflow is not restricted such as snow or debris blocking airflow
through the grill. If the gauge continues to show high temperatures, see
your authorized dealer.

TRANSMISSION CONTROL
Tow/Haul feature (5–speed automatic transmission) (if equipped)
To activate, press the transmission
control switch (TCS) located on the
gearshift. The TOW/HAUL indicator
light will illuminate in the
instrument cluster. The transmission
will operate in all gears. Press the
transmission control switch again to deactivate Tow/Haul mode. When
you shut off and re-start your vehicle, the transmission will automatically
return to normal mode with Tow/Haul feature deactivated, refer to the
Driving chapter for more information.
Do not use the Tow/Haul feature when driving in icy or slippery
conditions as the increased engine braking can cause the rear
wheels to slide and the vehicle to swing around with the possible loss
of vehicle control..
ILLUMINATED VISOR MIRROR (IF EQUIPPED)
Lift the mirror cover to turn on the
visor mirror lamps.
OVERHEAD CONSOLE (IF EQUIPPED)
The appearance of your vehicle’s overhead console will vary according to
your option package. If your vehicle is equipped with a moonroof, refer
to Moonroof later in this chapter for information on its operation.

Reasons given... Consider...
“I have an airbag” Airbags offer greater protection when
used with safety belts. Frontal airbags
are not designed to inflate in rear and
side crashes or rollovers.
“I’d rather be thrown clear” Not a good idea. People who are
ejected are 40 times more likely to
DIE. Safety belts help prevent ejection,
WE CAN’T “PICK OUR CRASH”.
Do not sit on top of a buckled safety belt to avoid the
BeltMinder chime. Sitting on the safety belt will increase the
risk of injury in an accident. To disable (one-time) or deactivate the
BeltMinder feature please follow the directions stated below.
One time disable
Any time the safety belt is buckled and then unbuckled during an ignition
ON cycle, the BeltMinder will be disabled for that ignition cycle only.
Deactivating/activating the BeltMinder feature
Read Step s1-9t horoughly before proceeding with the
deactivation/activation programming procedure.
The BeltMinder feature can be deactivated/activated by performing the
following procedure:
Before following the procedure, make sure that the following conditions
are met:
• the parking brake is set
• the gearshift is in P (Park) (automatic transmission) or the neutral
position (manual transmission)
• the ignition switch is in the OFF position
• all vehicle doors are closed
• the driver’s safety belt is unbuckled
• the parklamps/headlamps are in the OFF position (If the vehicle is
equipped with Autolamps, this will not affect the procedure)
To reduce the risk of injury, do not deactivate/activate the Belt
Minder feature while driving the vehicle.
