instrument cluster GMC YUKON 2006 Owner's Guide

SERVICE CHARGING SYSTEM
On some vehicles, if there is a problem with the battery
charging system, this message will appear on the
DIC. Under certain conditions, the battery warning light
may also turn on in the instrument panel cluster.
SeeBattery Warning Light on page 3-40. The battery
will not be charging at an optimal rate and the vehicle
will lose the ability to enter the fuel economy mode.
The vehicle is safe to drive, however you should have
the electrical system checked by your GM dealer.
Pressing any of the four DIC buttons will acknowledge
the message and clear it from the DIC display.
If your vehicle does not have the four DIC buttons,
pressing the trip odometer reset stem will acknowledge
the message and clear it from the DIC display.
SERVICE RIDE CONTROL
If a problem occurs with the suspension system, this
message will appear on the DIC. See your GM dealer.
Pressing any of the four DIC buttons will acknowledge
the message and clear it from the DIC display.
If your vehicle does not have the four DIC buttons,
pressing the trip odometer reset stem will acknowledge
the message and clear it from the DIC display.
SERVICE STABILITY
If you ever see the SERVICE STABILITY message, it
means there may be a problem with your StabiliTrak®
system. If you see this message, try to reset the system.
Stop; turn off the engine; then start the engine again.
If the SERVICE STABILITY message still comes
on, it means there is a problem. You should see your
GM dealer for service. The vehicle is safe to drive,
however, you do not have the benet of StabiliTrak
®,
so reduce your speed and drive accordingly.
Pressing any of the four DIC buttons will acknowledge
the message and clear it from the DIC display.
If your vehicle does not have the four DIC buttons,
pressing the trip odometer reset stem will acknowledge
the message and clear it from the DIC display.
3-63

There are several conditions that can cause this
message to appear.
One condition is overheating, which could occur if
StabiliTrak®activates continuously for an extended
period of time.
The message will also be displayed if the brake
system warning light is on. SeeBrake System
Warning Light on page 3-42.
The message could be displayed if the stability
system takes longer than usual to complete its
diagnostic checks due to driving conditions.
If an engine or vehicle related problem has been
detected and the vehicle needs service, the
message will appear. See your GM dealer.
The message will also appear if the vehicle is
shifted into 4LO.
The message will turn off as soon as the conditions
that caused the message to be displayed are no longer
present.
TIGHTEN FUEL CAP
If the vehicle’s fuel cap is not tightened properly, this
message may appear along with the check engine light
on the instrument panel cluster. SeeMalfunction
Indicator Lamp on page 3-46. Reinstall the fuel cap
fully. SeeFilling the Tank on page 5-8. The diagnostic
system can determine if the fuel cap has been left off or
improperly installed. A loose or missing fuel cap will
allow fuel to evaporate into the atmosphere. A few
driving trips with the cap properly installed should turn
this light and message off.
TRACTION ACTIVE
When the traction control system has detected that
any of the vehicle’s wheels are slipping, the traction
control system will activate and this message will appear
on the DIC. SeeStabiliTrak
®System on page 4-9for
more information.
TRACTION SYS (System) LIMITED
If the brake traction control system activates constantly
or if the brakes have heated up due to high-speed
braking, brake traction control will be disabled and the
TRACTION SYS LIMITED message will be displayed.
The system will return to normal operation after the
brakes have cooled. SeeStabiliTrak
®System on
page 4-9for more information.

TRANS (Transmission) HOT IDLE
ENGINE
Notice:If you drive your vehicle while the
transmission uid is overheating and the
transmission temperature warning is displayed on
the instrument panel cluster and/or DIC, you
can damage the transmission. This could lead to
costly repairs that would not be covered by
your warranty. Do not drive your vehicle with
overheated transmission uid or while the
transmission temperature warning is displayed.
If the transmission uid in the vehicle gets hot,
this message will appear on the DIC along with a
continuous chime. Driving with the transmission uid
temperature high can cause damage to the vehicle.
Stop the vehicle and let it idle to allow the transmission
to cool. This message will clear and the chime will
stop when the uid temperature reaches a safe level.
SeeTransmission Temperature Gage on page 3-44.
TRANSMISSION HOT
Notice:If you drive your vehicle while the
transmission uid is overheating and the
transmission temperature warning is displayed on
the instrument panel cluster and/or DIC, you
can damage the transmission. This could lead to
costly repairs that would not be covered by
your warranty. Do not drive your vehicle with
overheated transmission uid or while the
transmission temperature warning is displayed.
If the transmission uid temperature becomes high,
this message will appear on the DIC.
When the transmission enters the protection mode,
you may notice a change in the transmission shifting
patterns. When the transmission uid temperature
returns to normal, the display will turn off and the
transmission shifting patterns will return to normal.
If the vehicle has the Tow/Haul mode, use this feature if
the transmission is operating at higher temperatures
and/or the following situations exist, which can cause the
transmission to operate at higher temperatures:
Towing a trailer
Hot outside air temperatures
Hauling a large or heavy load

Engine Oil
If the CHECK OIL LEVEL message appears on the
instrument cluster, it means you need to check
your engine oil level right away.
For more information, see CHECK OIL LEVEL under
DIC Warnings and Messages on page 3-56.
You should check your engine oil level regularly; this is
an added reminder.
Checking Engine Oil
It is a good idea to check your engine oil every time you
get fuel. In order to get an accurate reading, the oil
must be warm and the vehicle must be on level ground.
The engine oil dipstick handle is a yellow loop.
SeeEngine Compartment Overview on page 5-12
for the location of the engine oil dipstick.
1. Turn off the engine and give the oil several minutes
to drain back into the oil pan. If you do not do this,
the oil dipstick might not show the actual level.
2. Pull out the dipstick and clean it with a paper towel
or cloth, then push it back in all the way. Remove it
again, keeping the tip down, and check the level.

How to Check
Use a good quality pocket-type gage to check tire
pressure. You cannot tell if your tires are properly
inated simply by looking at them. Radial tires may
look properly inated even when they’re underinated.
Check the tire’s ination pressure when the tires
are cold. Cold means your vehicle has been sitting
for at least three hours or driven no more than
1 mile (1.6 km).
Remove the valve cap from the tire valve stem. Press
the tire gage rmly onto the valve to get a pressure
measurement. If the cold tire ination pressure matches
the recommended pressure on the Tire and Loading
Information label, no further adjustment is necessary.
If the ination pressure is low, add air until you reach
the recommended amount.
If you overll the tire, release air by pushing on the
metal stem in the center of the tire valve. Recheck
the tire pressure with the tire gage.
Be sure to put the valve caps back on the valve
stems. They help prevent leaks by keeping out dirt
and moisture.
Tire Pressure Monitor System
The Tire Pressure Monitor System (TPMS) uses radio
and sensor technology to check tire pressure levels.
If your vehicle has this feature, sensors are mounted on
each tire and wheel assembly, except the spare tire.
The TPMS sensors monitor the air pressure in your
vehicle’s tires and transmit tire pressure readings to a
receiver located in the vehicle.
The TPMS is designed to alert the driver, if a low tire
pressure condition exists. This system also allows
the driver to check tire pressure levels using the Driver
Information Center (DIC).
When a low tire pressure condition is detected, the TPMS
displays the CHECK TIRE PRESSURE warning message
on the DIC, and at the same time illuminates the low tire
pressure warning symbol. For additional information
and details about the DIC operation and displays see
DIC Operation and Displays on page 3-53andDIC
Warnings and Messages on page 3-56.
You may notice, during cooler weather conditions, that
the tire pressure monitor light, located on the instrument
panel cluster, and the CHECK TIRE PRESSURE
message will appear when the vehicle is rst started and
then turn off as you start to drive the vehicle. This could
be an early indicator that the tire pressures are getting
low and need to be inated to the proper pressure.
