pressing the down arrow will turn the rear climate
control system off.
«Nª(Mode):Press the this button until
AUTO appears on the display to place the system
in automatic mode. When automatic operation
is active, the system will automatically control
the air delivery mode.
Manual Operation
«A ª(Fan):Press these up or down arrow
buttons to increase or decrease the fan speed.
«bª(Temperature):Press these up or
down arrow buttons to increase or decrease the
temperature for the rear seat passengers. Once the
rear setting temperature is altered from followingthe front setting temperature, it will no longer follow
changes to the front setting temperature until the
front climate control AUX button resets it.
«Nª(Mode):Press these buttons to change
the air delivery mode. If in AUTO air delivery
mode, pressing the up arrow button will cancel
automatic operation and place the system in
manual mode.
Y(Vent):This mode directs air to the upper
outlets.
%(Bi-Level):This mode directs half the air
to the upper outlets, and the other half to the oor
outlets.
[(Floor):This mode directs the air to the oor
outlets.
For more information on how to use the front
climate control system, seeDual Climate Control
System on page 210.
For more information on the air outlets, seeOutlet
Adjustment on page 217. Be sure to keep the
area under the front seats clear of any objects
so that the air inside of your vehicle can circulate
effectively.

SERVICE A/C SYSTEM
This message displays when the air delivery mode
door or the electronic sensors that control the air
conditioning and heating systems are no longer
working. Have the climate control system serviced
by your dealer if you notice a drop in heating and air
conditioning efficiency.
SERVICE BATTERY CHARGING
SYSTEM
This message displays when a problem with the
charging system has been detected. The charging
system light also displays on the instrument
panel cluster. SeeCharging System Light on
page 229for more information. Have your vehicle
serviced by your dealer.
SERVICE BRAKE ASSIST
This message displays if there is a problem with the
brake system. The brake system warning light and
the anti-lock brake system warning light may also
be displayed on the instrument panel cluster.
SeeBrake System Warning Light on page 229andAnti-Lock Brake System Warning Light on page 230
for more information. If this happens, stop as soon
as possible and turn off the vehicle. Restart the
vehicle and check for the message on the DIC
display. If the message is displayed or appears
again when you begin driving, the brake system
needs service. See your dealer as soon as
possible. SeeBrakes on page 387for more
information.
SERVICE BRAKE SYSTEM
This message displays if the ignition is on to
inform the driver that the brake uid level is low.
Have the brake system serviced by your dealer as
soon as possible.
SERVICE PARKING ASSIST
If your vehicle has the Ultrasonic Front and Rear
Parking Assist (UFRPA) system, this message
displays if there is a problem with the UFRPA
system. Do not use this system to help you park.
SeeUltrasonic Front and Rear Parking Assist
(UFRPA) on page 202for more information.
See your dealer for service.

If you get the overheat warning with no sign of
steam, try this for a minute or so:
1. In heavy traffic, let the engine idle in
NEUTRAL (N) while stopped. If it safe to do
so, pull off the road, shift to PARK (P) or
NEUTRAL (N) and let the engine idle.
2. Set the climate controls to the highest heat
setting and fan speed and open the windows
as necessary.
If you no longer have the overheat warning, you
can drive. Just to be safe, drive slower for
about 10 minutes. If the warning does not come
back on, you can drive normally.
If the warning continues, pull over, stop, and park
your vehicle right away.
If there is still no sign of steam, idle the engine for
three minutes while you are parked. If you still
have the warning, turn off the engine and
get everyone out of the vehicle until it cools down.
Also, see “Overheated Engine Protection
Operating Mode” later in this section.
You may decide not to lift the hood but to get
service help right away.Overheated Engine Protection
Operating Mode
If an overheated engine condition exists and the
message ENGINE OVERHEATED STOP ENGINE
is displayed, 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. Driving
extended miles (km) and/or towing a trailer in
the overheat protection mode should be avoided.
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. SeeEngine Oil on page 365.

While the tires available on General Motors
passenger cars and light trucks may vary with
respect to these grades, they must also conform to
federal safety requirements and additional General
Motors Tire Performance Criteria (TPC) standards.
Treadwear
The treadwear grade is a comparative rating
based on the wear rate of the tire when tested
under controlled conditions on a specied
government test course. For example, a tire
graded 150 would wear one and a half (1.5) times
as well on the government course as a tire
graded 100. The relative performance of tires
depends upon the actual conditions of their use,
however, and may depart signicantly from
the norm due to variations in driving habits, service
practices, and differences in road characteristics
and climate.
Traction – AA, A, B, C
The traction grades, from highest to lowest, are AA,
A, B, and C. Those grades represent the tire’s
ability to stop on wet pavement as measured under
controlled conditions on specied government test
surfaces of asphalt and concrete. A tire marked C
may have poor traction performance.Warning:The traction grade assigned to this tire
is based on straight-ahead braking traction
tests, and does not include acceleration, cornering,
hydroplaning, or peak traction characteristics.
Temperature – A, B, C
The temperature grades are A (the highest), B,
and C, representing the tire’s resistance to
the generation of heat and its ability to dissipate
heat when tested under controlled conditions on a
specied indoor laboratory test wheel. Sustained
high temperature can cause the material of the tire
to degenerate and reduce tire life, and excessive
temperature can lead to sudden tire failure.
The grade C corresponds to a level of performance
which all passenger car tires must meet under
the Federal Motor Vehicle Safety Standard
No. 109. Grades B and A represent higher levels
of performance on the laboratory test wheel
than the minimum required by law.
Warning:The temperature grade for this tire is
established for a tire that is properly inated
and not overloaded. Excessive speed,
underination, or excessive loading, either
separately or in combination, can cause heat
buildup and possible tire failure.
