Electrochromic Mirror Operation
The right side of the button, labeled TEMP and located
at the bottom of the mirror, turns the electrochromic
mirror on and off. An indicator light, located to the
right of the TEMP button, will come on when the
electrochromic mirror is turned on. To turn the mirror
on, press and hold the TEMP button for 15 seconds.
To turn the mirror off, press and hold the TEMP button
for 15 seconds. The indicator light will turn off.
Compass Operation
With the ignition on, the compass will show two character
boxes. The mirror will display the compass heading.
When cleaning the mirror, use a paper towel or similar
material dampened with glass cleaner. Do not spray
glass cleaner directly on the mirror as that may cause
the liquid cleaner to enter the mirror housing.Compass Calibration
The compass may need calibration if:
After five seconds, the display does not show a
compass heading (ªNº for North, for example),
there may be a strong magnetic field interfering with
the compass. Such interference may be caused by a
magnetic antenna mount, magnetic note pad holder
or a similar magnetic item.
The compass does not display the correct heading
and the compass zone variance is set correctly.
In order to calibrate, the letters ªCALº must be displayed
in the mirror compass windows. If ªCALº is not
displayed, push in the ªCOMPº button for approximately
eight seconds or until the letter ªCALº is displayed.
The compass can be calibrated in one of two ways:
Drive the vehicle in circles at five mph (8 km/h) or
less until the display reads a direction, or
Drive the vehicle on your everyday routine and after
several turns the compass will become calibrated and
will display a direction.

Adjust your outside mirrors so you can just see the side
of your vehicle and have a clear view of objects behind
you. The mirrors can be folded in to enter narrow areas.

2-55 Cargo Security Shade (If Equipped)
CAUTION:
An improperly stored cargo cover could be
thrown about the vehicle during a collision or
sudden maneuver. You or others could be
injured. If you remove the cover, always store it
outside of the vehicle. When you put it back,
always be sure that it is securely reattached.
If you have a cargo security shade, you can use it to
cover items in the cargo area of your vehicle.
To use the shade, pull the shade handle toward the rear
of the vehicle. Latch the shade posts into the retaining
sockets on the cargo area trim panels.
To return the shade to the retracted position, pull up on
the shade handle to release the shade posts from the
retaining sockets. Let the shade move forward to the full
retracted position.To remove the shade from the vehicle, first let the shade
go all the way into the holder. Then, grasping the
passenger's side shade endcap, push the shade endcap
toward the driver's side of the vehicle. The endcap
should lock in the compressed position. Lift the shade
up on the passenger's side, swing the shade rearward
and take it out of the vehicle.
To put the shade in the vehicle, first make sure the shade
slot in the holder faces rearward with the round surface
facing down. Then, hold the shade at an angle and place
the shade holder tab into the slot in the driver's side trim
panel. Move the other end of the shade forward and hold
it next to the passenger's side trim panel slot.
Push the button on top of the passenger's side endcap.
This will allow the shade to extend into the trim slot.
Lightly pull on the shade holder to make sure it is
secure. On Suburban/Yukon XL models there are
two slots. The slots furthest forward allow the shade to
be used if the third seat is removed or folded down.

2-73 Brake System Warning Light
With the ignition on, the brake system warning light will
flash when you set the parking brake. The light will flash
if the parking brake doesn't release fully. If you try to
drive with the parking brake engaged, a chime will sound
when the vehicle speed is greater than 3 mph (5 km/h).
Your vehicle's hydraulic brake system is divided into
two parts. If one part isn't working, the other part can
still work and stop you. For good braking, though, you
need both parts working well.
If the warning light comes on, there could be a brake
problem. Have your brake system inspected right away.
United States CanadaThis light should come on briefly when you turn the
ignition key to RUN. If it doesn't come on then, have it
fixed so it will be ready to warn you if there's a problem.
If the light comes on while you are driving, pull off the
road and stop carefully. You may notice that the pedal is
harder to push. Or, the pedal may go closer to the floor.
It may take longer to stop. If the light is still on, have the
vehicle towed for service. See ªTowing Your Vehicleº in
the Index.
CAUTION:
Your brake system may not be working properly
if the brake system warning light is on. Driving
with the brake system warning light on can lead
to an accident. If the light is still on after you've
pulled off the road and stopped carefully, have
the vehicle towed for service.

The following situations can cause the transmission to
operate at higher temperatures:
Towing a trailer
Hot outside air temperatures
Hauling a large or heavy load
Low transmission fluid level
High transmission fluid level
Restricted air flow to the radiator and the auxiliary
transmission oil cooler (if equipped).
A temporary solution to hotter transmission operating
temperatures may be to let the transmission cool down.
If the transmission is operated at higher temperatures on
a frequent basis, see ªScheduled Maintenanceº in the
Index for the proper transmission maintenance intervals.Low Traction Light (If Equipped)
If you have the Traction
Assist System, this light
will come on when the
system is limiting wheel
spin. See ªTraction Assist
Systemº in the Index.
You may feel or hear the system working or notice a
lack of accelerator response, but this is normal.
The LOW TRACTION light also comes on briefly when
you turn your ignition to RUN. If the light doesn't come
on then, the system may require service; have it fixed so
it will be there to tell you when the Traction Assist
System is active. Slippery road conditions may exist if
the LOW TRACTION light comes on, so adjust your
driving accordingly.
