Brake System Warning
Light The vehicle brake system consists
of electronically controlled hydraulic
brake circuits. If a fault is detected,
valves are adjusted to allow the
brake pedal to push brake fluid
directly into the hydraulic brake
circuits. When a fault occurs, the
brake system warning light comes
on, and Driver Information Center
(DIC) messages may display.
Vehicle speed may also be limited
and the amount of brake pedal force
applied may need to increase. Have
the vehicle brake system serviced
as soon as possible. Metric English
This light should come on briefly
when the engine is started. If it does
not come on then, have it fixed so it
will be ready to warn if there is a
problem.
The brake system warning light may
also come on when the parking
brake is set, if the vehicle has low
brake fluid, or if the brakes are
severely faded. See Brake Fluid
0 336 . If the brakes are overheated,
DIC messages may display, and the
vehicle speed may be limited. If the
brake fluid is not low, if the brakes
are not overheated, and if the
parking brake is fully released, then
the vehicle has a brake problem.
Have the vehicle brake system
serviced as soon as possible. If the light comes on while driving,
pull off the road and stop carefully.
The pedal might be harder to push,
or the pedal may go closer to the
floor. It could take longer to stop.
If the light is still on, have the
vehicle towed for service. See
Towing the Vehicle 0 398 .
{ WarningThe brake system might not be
working properly if the brake
system warning light is on.
Driving with the brake system
warning light on can lead to a
crash. If the light is still on after
the vehicle has been pulled off
the road and carefully stopped,
have the vehicle towed for
service.

Driving on Hills Driving safely on hills requires good
judgment and an understanding of
what the vehicle can and cannot do.
{ WarningMany hills are simply too steep
for any vehicle. Driving up hills
can cause the vehicle to stall.
Driving down hills can cause loss
of control. Driving across hills can
cause a rollover. You could be
injured or killed. Do not drive on
steep hills.
Before driving on a hill, assess the
steepness, traction, and
obstructions. If the terrain ahead
cannot be seen, get out of the
vehicle and walk the hill before
driving further. When driving on hills:
.
Use a low gear and keep a firm
grip on the steering wheel.
.
Maintain a slow speed.
.
When possible, drive straight up
or down the hill.
.
Slow down when approaching
the top of the hill.
.
Use headlamps even during the
day to make the vehicle more
visible.
{ WarningDriving to the top of a hill at high
speed can cause a crash. There
could be a drop-off, embankment,
cliff, or even another vehicle. You
could be seriously injured or
killed. As you near the top of a
hill, slow down and stay alert.
.
Never go downhill forward or
backward with either the
transmission or transfer case in N (Neutral). The brakes could
overheat and you could lose
control.
{ WarningIf the vehicle has the two-speed
automatic transfer case, shifting
the transfer case to N (Neutral)
can cause your vehicle to roll
even if the transmission is in
P (Park). This is because the
N (Neutral) position on the
transfer case overrides the
transmission. You or someone
else could be injured. If leaving
the vehicle, set the parking brake
and shift the transmission to
P (Park). Shift the transfer case to
any position but N (Neutral).
.
When driving down a hill, keep
the vehicle headed straight
down. Use a low gear because
the engine will work with the
brakes to slow the vehicle and
help keep the vehicle under
control.

GMC Sierra/Sierra Denali Owner Manual (GMNA-Localizing-U.S./Canada/
Mexico-1500-11698638) - 2019 - crc - 5/23/18
Driving and Operating 203
{ WarningHeavy braking when going down
a hill can cause your brakes to
overheat and fade. This could
cause loss of control and you or
others could be injured or killed.
Apply the brakes lightly when
descending a hill and use a low
gear to keep vehicle speed under
control.
If a brake fade condition is detected,
a DIC warning message is
displayed. Adjust brake pedal use
and shift to a lower transmission
gear to reduce braking.
If the brakes continue to fade to a
severe condition, additional DIC
warning messages are displayed.
The brake system warning light will
illuminate, and the vehicle speed
may be limited. See Brake System
Warning Light 0 151 . If the vehicle stalls on a hill:
1. Apply the brakes to stop the
vehicle, and then apply the
parking brake.
2. Shift into P (Park) and then
restart the engine.
.
If driving uphill when the
vehicle stalls, shift to
R (Reverse), release the
parking brake, and back
straight down.
.
Never try to turn the vehicle
around. If the hill is steep
enough to stall the vehicle,
it is steep enough to cause
it to roll over.
.
If you cannot make it up the
hill, back straight down
the hill.
.
Never back down a hill in
N (Neutral) using only the
brake. The vehicle can roll
backward quickly and you
could lose control. .
If driving downhill when the
vehicle stalls, shift to a
lower gear, release the
parking brake, and drive
straight down the hill.
3. If the vehicle cannot be
restarted after stalling, set the
parking brake, shift into
P (Park), and turn the
vehicle off.
3.1. Leave the vehicle and
seek help.
3.2. Stay clear of the path the
vehicle would take if it
rolled downhill.
.
Avoid turns that take the vehicle
across the incline of the hill.
A hill that can be driven straight
up or down might be too steep to
drive across. Driving across an
incline puts more weight on the
downhill wheels, which could
cause a downhill slide or a
rollover.
.
Surface conditions can be a
problem. Loose gravel, muddy
spots, or even wet grass can
cause the tires to slip sideways,

218 Driving and Operating 3. Continue to hold the brake
pedal, then set the parking
brake. See Electric Parking
Brake 0 241 .
4. Push the key all the way in
toward the steering column,
then turn the key to
LOCK/OFF.
5. Remove the key.
6. Release the brake pedal.
See your dealer if the key can be
removed in any other position.
Retained Accessory Power (RAP)
will remain active. See Retained
Accessory Power (RAP) 0 225 .
A warning chime will sound when
the driver door is opened and the
key is in the ignition.
If equipped with a locking steering
column, the steering can bind with
the front wheels turned off center,
which may prevent key rotation out
of LOCK/OFF. If this happens, move
the steering wheel from right to left
while turning the key to ACC/
ACCESSORY. If this does not work,
then the vehicle needs service. { WarningTurning off the vehicle while
moving may cause loss of power
assist in the brake and steering
systems and disable the airbags.
While driving, turn off the vehicle
only in an emergency.
In an emergency, if the vehicle
cannot be pulled over and must be
turned off while driving:
1. Push the key all the way in
toward the steering column,
then turn the key to ACC/
ACCESSORY.
2. Brake using firm and steady
pressure. Do not pump the
brakes repeatedly. This may
deplete power assist, requiring
increased brake pedal force.
3. Shift the vehicle to N (Neutral).
This can be done while the
vehicle is moving. Continue
braking and steer the vehicle to
a safe location.
4. Come to a complete stop. 5. Shift to P (Park) with an
automatic transmission,
or Neutral with a manual
transmission.
6. Continue to hold the brake
pedal, then set the parking
brake. See Electric Parking
Brake 0 241 .
7. Push the key all the way in
toward the steering column,
then turn the ignition to
LOCK/OFF.
8. Remove the key.
9. Release the brake pedal.
CautionUse the correct key, make sure it
is all the way in — or pushed all
the way in toward the steering
column when turning off the
vehicle — and turn it only with
your hand.
