TIRE TRAINING (Except Z06):The Tire Pressure
Monitor (TPM) operates with battery-powered sensors
that are located inside the valve stems on each tire.
Each sensor has a unique ID code so the vehicle knows
the tire location of the sensor. When the vehicle
reaches a speed of greater than 15 mph (24 km/h), the
sensors begin to send the tire pressure readings to
a receiver inside the vehicle. These readings are
displayed when using the GAGES button on the DIC. If
you are unable to display your tire pressures while
the vehicle speed is greater than 15 mph (24 km/h), you
may need to have your sensor ID codes learned by
the vehicle. See your dealer.

Adding Coolant
If you need more coolant, add the proper DEX-COOLž
coolant mixtureat the surge tank,but only when the
engine is cool.
{CAUTION:
You can be burned if you spill coolant on hot
engine parts. Coolant contains ethylene glycol,
and it will burn if the engine parts are hot
enough. Don't spill coolant on a hot engine.
When replacing the pressure cap, make sure it is
hand-tight.
Coolant Surge Tank Pressure Cap
Notice:Your pressure cap is a pressure-type
cap and must be tightly installed to prevent coolant
loss and possible engine damage from overheating.
See ªCapacities and Speci®cationsº for more
information.
See
Engine Compartment Overview on page 5-12for
information on location.
Engine Overheating
You will ®nd an engine coolant temperature gage on the
instrument panel cluster and a COOLANT OVER
TEMP message on the Driver Information Center (DIC).
See
Engine Coolant Temperature Gage on page 3-38andDIC Warnings and Messages on page 3-53.
Overheated Engine Protection
Operating Mode
If an overheated engine condition exists and the
messages COOLANT OVER TEMP and REDUCED
ENGINE POWER are displayed, along with the Check
Engine light, an overheat protection mode which
alternates ®ring groups of cylinders helps prevent engine
damage. In this mode, you will notice a loss in power
and engine performance. This operating mode
allows your vehicle to be driven to a safe place in an
emergency; you may drive up to 50 miles (80 km).
Notice:After driving in the overheated engine
protection operating mode, to avoid engine damage,
allow the engine to cool before attempting any
repair. The engine oil will be severely degraded.
Repair the cause of coolant loss, change the oil
and reset the oil life system. See ªEngine Oilº in
the Index.

If a tire's in¯ation pressure is between 5 psi (35 kPa)
and 25 psi (170 kPa), you will see a message on
the Driver Information Center. This message will show
which tire is underin¯ated and two chimes will sound. An
example would be LOW TIRE PRESSURE-LR. This
would mean that the in¯ation pressure in your left rear
tire is between 5 psi (35 kPa) and 25 psi (170 kPa).
If the in¯ation pressure in the tire drops below
5 psi (35 kPa), the message would read FLAT TIRE-LR
and four chimes will sound. See
Driver Information
Center (DIC) on page 3-44.
The TPM will also alert you if a tire's pressure is higher
than 42 psi (290 kPa). The message will show which
tire is overin¯ated and two chimes will sound. An
example would be HIGH PRESSURE-LR. This would
mean that the in¯ation pressure in your left rear tire
is higher than 42 psi (290 kPa). See

Here are some cleaning tips:
·Always read the instructions on the cleaner label.
·Clean up stains as soon as you can ± before
they set.
·Carefully scrape off any excess stain.
·Use a clean cloth or sponge, and change to a clean
area often. A soft brush may be used if stains are
stubborn.
·If a ring forms on fabric after spot cleaning, clean
the entire area immediately or it will set.
Cleaning Coated Moldings
These moldings are around the hatch opening in the
rear area.
·When lightly soiled, wipe with a sponge or soft
lint-free cloth dampened with water.
·When heavily soiled, use warm soapy water.
Cleaning Leather
Use a soft cloth with lukewarm water and a mild soap or
saddle soap and wipe dry with a soft cloth. Then, let
the leather dry naturally. Do not use heat to dry.
·For stubborn stains, use a leather cleaner.
·Neveruse oils, varnishes, solvent-based or abrasive
cleaners, furniture polish or shoe polish on leather.
·Soiled or stained leather should be cleaned
immediately. If dirt is allowed to work into the ®nish,
it can harm the leather.
Cleaning the Top of the Instrument
Panel
Use only mild soap and water to clean the top surfaces
of the instrument panel. Sprays containing silicones
or waxes may cause annoying re¯ections in the
windshield and even make it difficult to see through the
windshield under certain conditions.
