Driving and Operating 185L (Low) will prevent shifting to a
lower gear range if the engine
speed is too high. If vehicle speed is
not reduced within the time allowed,
the lower gear range shift will not be
completed. Slow the vehicle, then
press the − (Minus) button to the
desired lower gear range.
While using the ERS, cruise control
can be used.
Drive Systems All-Wheel Drive Vehicles with this feature transfer
engine power, as required, to all
four wheels. It is fully automatic, and
adjusts itself as needed for road
conditions.
When using a compact spare tire on
an AWD vehicle, the system
automatically detects the compact
spare and reduces AWD
performance to protect the system.
An AWD message may be
displayed. To restore full AWD
operation and prevent excessive
wear on the system, replace the
compact spare with a full-size tire as
soon as possible. See Compact
Spare Tire 0 292 .Brakes Antilock Brake
System (ABS) The Antilock Brake System (ABS)
helps prevent a braking skid and
maintain steering while
braking hard.
ABS performs a system check when
the vehicle is first driven.
A momentary motor or clicking noise
may be heard while this test is going
on, and the brake pedal may move
slightly. This is normal.
If there is a problem with ABS, this
warning light stays on. See Antilock
Brake System (ABS) Warning Light
0 118 .

Buick Envision Owner Manual (GMNA-Localizing-U.S./Canada/Mexico-
13555857) - 2020 - CRC - 2/25/19
186 Driving and Operating ABS does not change the time
needed to get a foot on the brake
pedal and does not always
decrease stopping distance. If you
get too close to the vehicle ahead,
there will not be enough time to
apply the brakes if that vehicle
suddenly slows or stops. Always
leave enough room ahead to stop,
even with ABS.
Using ABS Do not pump the brakes. Just hold
the brake pedal down firmly.
Hearing or feeling ABS operate is
normal.
Braking in Emergencies ABS allows steering and braking at
the same time. In many
emergencies, steering can help
even more than braking. Electric Parking Brake
The Electric Parking Brake (EPB)
switch is on the center console. The
EPB can always be activated, even
if the ignition is off. To prevent
draining the battery, avoid repeated
cycles of the EPB when the engine
is not running.
The system has a red parking brake
status light and an amber parking
brake warning light. See Electric
Parking Brake Light 0 117 and
Service Electric Parking Brake Light
0 118 . There are also parking
brake-related Driver Information Center (DIC) messages. In case of
insufficient electrical power, the EPB
cannot be applied or released.
Before leaving the vehicle, check
the red parking brake status light to
ensure that the parking brake is
applied.
EPB Apply To apply the EPB:
1. Be sure the vehicle is at a
complete stop.
2. Lift up the EPB switch
momentarily.
The red parking brake status light
will flash and then stay on once the
EPB is fully applied. If the red
parking brake status light flashes
continuously, then the EPB is only
partially applied or there is a
problem with the EPB. A DIC
message will display. Release the
EPB and try to apply it again. If the
light does not come on, or keeps
flashing, have the vehicle serviced.
Do not drive the vehicle if the red

Driving and Operating 189vehicle wheel brakes to assist the
driver in keeping the vehicle on the
intended path.
If cruise control is being used and
TCS or StabiliTrak/ESC begins to
limit wheel spin, cruise control will
disengage. Cruise control may be
turned back on when road
conditions allow.
Both systems come on
automatically when the vehicle is
started and begins to move. The
systems may be heard or felt while
they are operating or while
performing diagnostic checks. This
is normal and does not mean there
is a problem with the vehicle.
It is recommended to leave both
systems on for normal driving
conditions, but it may be necessary
to turn TCS off if the vehicle gets
stuck in sand, mud, ice, or snow.
See If the Vehicle Is Stuck 0 168
and “ Turning the Systems Off and
On ” later in this section. The indicator light for both systems
is in the instrument cluster. This
light will:
.
Flash when TCS is limiting
wheel spin.
.
Flash when StabiliTrak/ESC is
activated.
.
Turn on and stay on when either
system is not working.
If either system fails to turn on or to
activate,
d comes on and stays on
to indicate that the system is
inactive and is not assisting the
driver in maintaining control. The
vehicle is safe to drive, but driving
should be adjusted accordingly.
If
d comes on and stays on:
1. Stop the vehicle.
2. Turn the engine off and wait
15 seconds. 3. Start the engine.
Drive the vehicle. If
d comes on
and stays on, the vehicle may need
more time to diagnose the problem.
If the condition persists, see your
dealer.
Turning the Systems Off
and On
CautionDo not repeatedly brake or
accelerate heavily when TCS is
off. The vehicle driveline could be
damaged.

Brake Fluid The brake master cylinder reservoir
is filled with GM approved DOT 4
brake fluid as indicated on the
reservoir cap. See Engine
Compartment Overview 0 234 for
the location of the reservoir.
Checking Brake Fluid
With the vehicle in P (Park) on a
level surface, the brake fluid level
should be between the minimum
and maximum marks on the brake
fluid reservoir.
There are only two reasons why the
brake fluid level in the reservoir may
go down:
.
Normal brake lining wear. When
new linings are installed, the
fluid level goes back up. .
A fluid leak in the brake
hydraulic system. Have the
brake hydraulic system fixed.
With a leak, the brakes will not
work well.
Always clean the brake fluid
reservoir cap and the area around
the cap before removing it.
Do not top off the brake fluid.
Adding fluid does not correct a leak.
If fluid is added when the linings are
worn, there will be too much fluid
when new brake linings are
installed. Add or remove fluid, as
necessary, only when work is done
on the brake hydraulic system.
{ Warning
If too much brake fluid is added, it
can spill on the engine and burn,
if the engine is hot enough. You
or others could be burned, and
the vehicle could be damaged.
Add brake fluid only when work is
done on the brake hydraulic
system. When the brake fluid falls to a low
level, the brake warning light comes
on. See Brake System Warning
Light 0 117 .
Brake fluid absorbs water over time
which degrades the effectiveness of
the brake fluid. Replace brake fluid
at the specified intervals to prevent
increased stopping distance. See
Maintenance Schedule 0 311 .
What to Add
Use only GM approved DOT 4
brake fluid from a clean, sealed
container. See Recommended
Fluids and Lubricants 0 320 .
{ Warning
The wrong or contaminated brake
fluid could result in damage to the
brake system. This could result in
the loss of braking leading to a
possible injury. Always use the
proper GM approved brake fluid.
