brake light GMC ENVOY 2007 Owner's Manual

If the engine stalls and the security light ashes,
wait about 10 minutes until the light stops
ashing before trying to restart the engine.
Remember to release the key from START as
soon as the engine starts.
If the engine does not start after three tries, the
vehicle needs service.
If the engine is running and the security light
comes on, you will be able to restart the engine if
you turn the engine off. However, your
Passlock
®system is not working properly and
must be serviced by your dealer. Your vehicle is
not protected by Passlock
®at this time. You
may also want to check the fuse. SeeFuses and
Circuit Breakers on page 493. See your dealer
for service.
In an emergency, call the GM Roadside
Assistance Center. SeeRoadside Assistance
Program on page 532.
Starting and Operating Your
Vehicle
New Vehicle Break-In
Notice:Your vehicle does not need an
elaborate break-in. But it will perform better in
the long run if you follow these guidelines:
Keep your speed at 55 mph (88 km/h)
or less for the rst 500 miles (805 km).
Do not drive at any one constant speed,
fast or slow, for the rst 500 miles (805 km).
Do not make full-throttle starts. Avoid
downshifting to brake, or slow, the vehicle.
Avoid making hard stops for the rst
200 miles (322 km) or so. During this time
your new brake linings are not yet broken
in. Hard stops with new linings can mean
premature wear and earlier replacement.
Follow this breaking-in guideline every time
you get new brake linings.
Do not tow a trailer during break-in. See
Towing a Trailer on page 362for the trailer
towing capabilities of your vehicle and more
information.
Following break-in, engine speed and load can
be gradually increased.

{CAUTION:
If you leave your cruise control on when
you are not using cruise, you might hit a
button and go into cruise when you do
not want to. You could be startled and
even lose control. Keep the cruise control
switch off until you want to use cruise
control.
Setting Cruise Control
1. Move the cruise control switch to on.
2. Get up to the speed you want.
3. Press the set button at the end of the lever
and release it.
4. Take your foot off the accelerator pedal.
The accelerator pedal will not go down.Some vehicles have a
cruise light on the
instrument panel cluster
that will come on
when the cruise control
is engaged.
Resuming a Set Speed
Suppose you set your cruise control at a desired
speed and then you apply the brake. This, of
course, shuts off the cruise control. But you do not
need to reset it.
Once you are going about 25 mph (40 km/h) or
more, you can move the cruise control switch
briey from on to resume/accelerate.
You will go right back up to the previously chosen
speed and stay there.
If you hold the switch at resume/accelerate, the
vehicle keeps going faster until you release
the switch or apply the brakes. So unless you
want to go faster, do not hold the switch at
resume/accelerate.
177

Increasing Speed While Using
Cruise Control
There are two ways to go to a higher speed:
Use the accelerator pedal to get to the higher
speed. Press the button at the end of the
lever, then release the button and the
accelerator pedal. You will now cruise at the
higher speed.
Move the cruise switch from on to resume/
accelerate. Hold it there until you get up to the
desired speed and then release the switch. To
increase your speed in very small amounts,
move the switch briey to resume/accelerate.
Each time you do this, your vehicle will go
about 1 mph (1.6 km/h) faster.
Reducing Speed While Using
Cruise Control
Press in the set button at the end of the lever until
you reach the desired speed, then release it.
Each time you do this, you will go about
1 mph (1.6 km/h) slower.
Passing Another Vehicle While Using
Cruise Control
Use the accelerator pedal to increase your speed.
When you take your foot off the pedal, your
vehicle will slow down to the cruise control speed
set earlier.
Using Cruise Control on Hills
How well your cruise control works on hills
depends upon your speed, load and the steepness
of the hills. When going up steep hills, you may
want to step on the accelerator pedal to maintain
your speed. When going downhill, you may
have to brake or shift to a lower gear to keep your
speed down. Of course, applying the brake
takes you out of cruise control. Many drivers nd
this to be too much trouble and do not use
cruise control on steep hills.
Ending Cruise Control
There are three ways to turn off the cruise control:
Step lightly on the brake pedal.
Move the cruise switch to off, or
Shift the transmission to NEUTRAL (N).
178

Readings in the low warning zone may occur
when a large number of electrical accessories are
operating in the vehicle and the engine is left
idling for an extended period. This condition
is normal since the charging system is not able to
provide full power at engine idle. As engine
speeds are increased, this condition should correct
itself as higher engine speeds allow the charging
system to create maximum power.
You can only drive for a short time with the
reading in either warning zone. If you must drive,
turn off all unnecessary accessories.
Readings in either warning zone indicate a
possible problem in the electrical system. Have
the vehicle serviced as soon as possible.
Brake System Warning Light
When the ignition is on, the brake system warning
light will come on when you set your parking
brake. The light will stay on if your parking brake
does not release fully. If it stays on after your
parking brake is fully released, it means your
vehicle has a brake problem. A chime may also
sound when the light comes on.Your vehicle’s hydraulic brake system is divided
into two parts. If one part is not 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.
This light should come on briey when you turn
the ignition key to RUN. If it does not come
on then, have it xed so it will be ready to warn
you if there is 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 oor. It may take longer to stop. If the light is
still on, have the vehicle towed for service. See
Towing Your Vehicle on page 354.

{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 have pulled
off the road and stopped carefully, have
the vehicle towed for service.
Anti-Lock Brake System
Warning Light
With the Anti-Lock
Brake System (ABS),
this light will come
on when you start your
engine and may
stay on for several
seconds, that is normal.
A chime may also sound when the light comes on.If the light stays on, or comes on when you are
driving, your vehicle needs service. If the regular
brake system warning light is not on, you still have
brakes, but you do not have anti-lock brakes. If the
regular brake system warning light is also on, you
do not have anti-lock brakes and there is a problem
with your regular brakes. SeeBrake System
Warning Light on page 206earlier in this section.
The ABS warning light should come on briey
when you turn the ignition key to RUN. If the light
does not come on then, have it xed so it will
be ready to warn you if there is a problem.
StabiliTrak®Service Light
This light will come on
briey when the engine
is started.
This light will come on if a problem is detected in
the StabiliTrak
®system.
