P :This position locks the front
wheels. Use P (Park) when starting
the engine because the vehicle
cannot move easily.
{Warning
It is dangerous to get out of the
vehicle if the shift lever is not fully
in P (Park) with the parking brake
firmly set. The vehicle can roll.
(Continued)
Warning (Continued)
Do not leave the vehicle when the
engine is running. If you have left
the engine running, the vehicle
can move suddenly. You or others
could be injured. To be sure the
vehicle will not move, even when
you are on fairly level ground,
always set the parking brake and
move the shift lever to P (Park).
SeeShifting Into Park 0188.
The vehicle has an automatic
transmission shift lock control
system. You must fully apply the
regular brake first and then press
the shift lever button before shifting
from P (Park) when the ignition is in
on. If you cannot shift out of
P (Park), ease pressure on the shift
lever, then push the shift lever all
the way into P (Park) as you
maintain brake application. Then
press the shift lever button and
move the shift lever into another
gear. See Shifting out of Park 0189.
R : Use this gear to back up.
Caution
Shifting to R (Reverse) while the
vehicle is moving forward could
damage the transmission. The
repairs would not be covered by
the vehicle warranty. Shift to
R (Reverse) only after the vehicle
is stopped.
To rock the vehicle back and forth to
get out of snow, ice, or sand without
damaging the transmission, see If
the Vehicle Is Stuck 0178.
N : In this position the engine does
not connect with the wheels. Use
N (Neutral) to restart a vehicle that
is already moving.
{Warning
Shifting into a drive gear while the
engine is running at high speed is
dangerous. Unless your foot is
firmly on the brake pedal, the
vehicle could move very rapidly.

192 Driving and Operating
Warning (Continued)
You could lose control and hit
people or objects. Do not shift
into a drive gear while the engine
is running at high speed.
Caution
Shifting out of P (Park) or
N (Neutral) with the engine
running at high speed may
damage the transmission. The
repairs would not be covered by
the vehicle warranty. Be sure the
engine is not running at high
speed when shifting the vehicle.
D : This position is for normal
driving. It provides the best fuel
economy. If you need more power
for passing, and you are:
. Going less than 56 km/h
(35 mph), push the accelerator
pedal about halfway down. .
Going about 56 km/h (35 mph) or
more, push the accelerator all
the way down.
Caution
If the vehicle does not shift gears,
the transmission could be
damaged. Have the vehicle
serviced right away.
Caution
A transmission hot message may
display if the automatic
transmission fluid is too hot.
Driving under this condition can
damage the vehicle. Stop and idle
the engine to cool the automatic
transmission fluid. This message
clears when the transmission fluid
has cooled sufficiently.
Caution
Spinning the tires or holding the
vehicle in one place on a hill
using only the accelerator pedal
may damage the transmission.
The repair will not be covered by
the vehicle warranty. If the vehicle
is stuck, do not spin the tires.
When stopping on a hill, use the
brakes to hold the vehicle in
place.
L : This position provides access to
gear ranges, which offer more
engine braking but lower fuel
economy than D (Drive). This can
be used on very steep hills, or in
deep snow or mud. See Manual
Mode 0193.
Operating Modes
The transmission may operate in a
lower gear than normal to improve
vehicle performance. The engine

11434432) - 2018 - CRC - 10/25/17
Driving and Operating 193
speed may be higher and there may
be an increase in noise during the
following conditions:
.When climbing a grade
. When driving downhill
. When driving in hot
temperatures or at high altitude
Manual Mode
Electronic Range Select
(ERS) Mode
ERS or manual mode allows for the
selection of the range of gear
positions. Use this mode when
driving downhill or to limit the top
gear and vehicle speed. The shift
position indicator within the Driver
Information Center (DIC) will display
a number next to the L indicating
the highest available gear under
manual mode and the driving
conditions when manual mode was
selected.
To use this feature:
1. Move the shift lever to L (Low).
2. Press the plus/minus button on the shift lever to increase or
decrease the gear range
available. When shifting to L (Low), the
transmission will shift to a preset
lower gear range. For this preset
range, the highest gear available is
displayed next to the L in the DIC.
See
Driver Information Center (DIC)
(Base Level) 0134 orDriver
Information Center (DIC) (Uplevel)
0 137. All gears below that number
are available to use. For example,
when 4 (Fourth) is shown next to the
L, 1 (First) through 4 (Fourth) gears
are shifted automatically. To shift to
5 (Fifth) gear or higher, press the
+ (Plus) button or shift into D (Drive).
L (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.

Driving and Operating 201
Reducing Speed While Using
Cruise Control
If the cruise control system is
already activated:
.Press and hold SET– down until
the desired lower speed is
reached, then release it.
. To decrease the vehicle speed in
small increments, press SET–
down briefly. For each press, the
vehicle goes about 1.6 km/h
(1 mph) slower.
Passing Another Vehicle While
Using Cruise Control
Use the accelerator pedal to
increase the vehicle speed. When
you take your foot off the pedal, the
vehicle will slow down to the
previously set cruise speed. While
pressing the accelerator pedal or
shortly following the release to
override cruise control, briefly
pressing SET− will result in cruise
set to the current vehicle speed. Using Cruise Control on Hills
How well the cruise control will work
on hills depends upon the vehicle
speed, load, and the steepness of
the hills. When going up steep hills,
you might have to step on the
accelerator pedal to maintain your
speed. When going downhill, you
might have to brake or shift to a
lower gear to keep your speed
down. If the brake pedal is applied,
cruise control will disengage.
Ending Cruise Control
There are four ways to end cruise
control:
.
Step lightly on the brake pedal.
. Press
*.
. Shift the transmission to
N (Neutral).
. To turn off cruise control,
press
5.
Erasing Speed Memory
The cruise control set speed is
erased from memory if
5is pressed
or if the ignition is turned off.
Adaptive Cruise Control
If equipped with Adaptive Cruise
Control (ACC), it allows you to
select the cruise control set speed
and following gap. Read this entire
section before using this system.
The following gap is the following
time between your vehicle and a
vehicle detected directly ahead in
your path moving in the same
direction. If no vehicle is detected in
your path, ACC works like regular
cruise control. ACC uses camera
and radar sensors. See Radio
Frequency Statement 0337.
If a vehicle is detected in your path,
ACC can apply acceleration or
limited, moderate braking to
maintain the selected following gap.
To disengage ACC, apply the brake.
If ACC is controlling your vehicle
speed when the Traction Control
System (TCS) or StabiliTrak system
activates, the ACC may
automatically disengage. See
Traction Control/Electronic Stability
Control 0197. When road

Driving and Operating 227
.Do not tow a trailer during the
first 800 km (500 mi), to prevent
damage to the engine, axle,
or other parts.
. Then, during the first 800 km
(500 mi) of trailer towing, do not
drive over 80 km/h (50 mph) and
do not make starts at full throttle.
. The vehicle can tow in D (Drive)
but manual mode is
recommended. See Manual
Mode 0193. Use a lower gear if
the transmission shifts too often.
. Turn off Parking Assist when
towing.
. Turn off Lane Keep Assist (LKA)
when towing. See Lane Keep
Assist (LKA) 0221.
{Warning
When towing a trailer, exhaust
gases may collect at the rear of
the vehicle and enter if the
liftgate, trunk/hatch, or rear-most
window is open.
(Continued)
Warning (Continued)
When towing a trailer:
. Do not drive with the
liftgate, trunk/hatch,
or rear-most window open.
. Fully open the air outlets on
or under the instrument
panel.
. Also adjust the climate
control system to a setting
that brings in only outside
air. See “Climate Control
Systems” in the Index.
For information about carbon
monoxide, see Engine Exhaust
0 190.
Towing a trailer requires a certain
amount of experience. The
combination you are driving is
longer and not as responsive as the
vehicle itself. Get acquainted with
the handling and braking of the rig
before setting out for the open road. Before starting, check all trailer hitch
parts and attachments, safety
chains, electrical connectors, lamps,
tires, and mirrors. If the trailer has
electric brakes, start the
combination moving and then apply
the trailer brake controller by hand
to be sure the brakes work.
During the trip, check occasionally
to be sure that the load is secure
and the lamps and any trailer
brakes still work.
Towing with a Stability Control
System
When towing, the sound of the
stability control system might be
heard. The system is reacting to the
vehicle movement caused by the
trailer, which mainly occurs during
cornering. This is normal when
towing heavier trailers.
Following Distance
Stay at least twice as far behind the
vehicle ahead as you would when
driving the vehicle without a trailer.

Buick Envision Owner Manual (GMNA-Localizing-U.S./Canada/Mexico-
11434432) - 2018 - CRC - 10/25/17
228 Driving and Operating
This can help to avoid situations
that require heavy braking and
sudden turns.
Passing
More passing distance is needed
when towing a trailer. Because the
rig is longer, it is necessary to go
farther beyond the passed vehicle
before returning to the lane.
Backing Up
Hold the bottom of the steering
wheel with one hand. To move the
trailer to the left, move your hand to
the left. To move the trailer to the
right, move your hand to the right.
Always back up slowly and,
if possible, have someone
guide you.
Making TurnsCaution
Making very sharp turns while
trailering could cause the trailer to
come in contact with the vehicle. (Continued)
Caution (Continued)
The vehicle could be damaged.
Avoid making very sharp turns
while trailering.
When turning with a trailer, make
wider turns than normal so the
trailer will not strike soft shoulders,
curbs, road signs, trees, or other
objects. Use the turn signal well in
advance and avoid jerky or sudden
maneuvers.
Turn Signals When Towing a
Trailer
The turn signal indicators on the
instrument cluster flash whenever
signaling a turn or lane change.
Properly hooked up, the trailer
lamps also flash, telling other
drivers the vehicle is turning,
changing lanes, or stopping.
When towing a trailer, the arrows on
the instrument cluster flash for turns
even if the bulbs on the trailer are burned out. Check occasionally to
be sure the trailer bulbs are still
working.
Driving on Grades
Reduce speed and shift to a lower
gear before starting down a long or
steep downgrade. If the
transmission is not shifted down, the
brakes might have to be used so
much that they would get hot and no
longer work well.
The vehicle can tow in D (Drive).
Use a lower gear if the transmission
shifts too often.
When towing at high altitude on
steep uphill grades, engine coolant
boils at a lower temperature than at
normal altitudes. If the engine is
turned off immediately after towing
at high altitude on steep uphill
grades, the vehicle could show
signs similar to engine overheating.
To avoid this, let the engine run
while parked, preferably on level
ground, with the transmission in
P (Park) for a few minutes before

Buick Envision Owner Manual (GMNA-Localizing-U.S./Canada/Mexico-
11434432) - 2018 - CRC - 10/25/17
Driving and Operating 229
turning the engine off. If the
overheat warning comes on, see
Engine Overheating0250.
Parking on Hills
{Warning
Parking the vehicle on a hill with
the trailer attached can be
dangerous. If something goes
wrong, the rig could start to move.
People can be injured, and both
the vehicle and the trailer can be
damaged. When possible, always
park the rig on a flat surface.
If parking the rig on a hill: 1. Press the brake pedal, but do not shift into P (Park) yet. Turn
the wheels into the curb if
facing downhill or into traffic if
facing uphill.
2. Have someone place chocks under the trailer wheels. 3. When the wheel chocks are in
place, release the brake pedal
until the chocks absorb
the load.
4. Reapply the brake pedal. Then apply the parking brake and
shift into P (Park).
5. Release the brake pedal.
Leaving After Parking on a Hill
1. Apply and hold the brake pedal while you:
1.1. Start the engine.
1.2. Shift into a gear.
1.3. Release the parking brake.
2. Let up on the brake pedal.
3. Drive slowly until the trailer is clear of the chocks.
4. Stop and have someone pick up and store the chocks.
Maintenance When Trailer
Towing
The vehicle needs service more
often when pulling a trailer. See the
Maintenance Schedule 0312.
Things that are especially important
in trailer operation are automatic
transmission fluid, engine oil, axle
lubricant, belts, cooling system, and
brake system. Inspect these before
and during the trip.
Check periodically to see that all
hitch nuts and bolts are tight.
Engine Cooling When Trailer
Towing
The cooling system may temporarily
overheat during severe operating
conditions. See Engine Overheating
0 250.

244 Vehicle Care
When the system has calculated
that oil life has been diminished, it
indicates that an oil change is
necessary. A CHANGE ENGINE
OIL SOON message comes on.
Change the oil as soon as possible
within the next 1 000 km (600 mi).
It is possible that, if driving under
the best conditions, the oil life
system may indicate that an oil
change is not necessary for up to a
year. The engine oil and filter must
be changed at least once a year
and at this time the system must be
reset. Your dealer has trained
service people who will perform this
work and reset the system. It is also
important to check the oil regularly
over the course of an oil drain
interval and keep it at the proper
level.
If the system is ever reset
accidentally, the oil must be
changed at 5 000 km (3,000 mi)
since the last oil change.
Remember to reset the oil life
system whenever the oil is changed.How to Reset the Engine Oil
Life System
Reset the system whenever the
engine oil is changed so that the
system can calculate the next
engine oil change. To reset the
system:1. Using the DIC controls on the right side of the steering wheel,
display REMAINING OIL LIFE
on the DIC. See Driver
Information Center (DIC) (Base
Level) 0134 orDriver
Information Center (DIC)
(Uplevel) 0137. When
remaining oil life is low, the
CHANGE ENGINE OIL SOON
message will appear on the
display.
2. Press
Von the DIC controls
and hold down for a few
seconds to clear the CHANGE
ENGINE OIL SOON message
and reset the oil life at 100%.
Be careful not to reset the oil
life display accidentally at any
time other than after the oil is changed. It cannot be reset
accurately until the next oil
change.
The system is reset when the
CHANGE ENGINE OIL SOON
message is off.
If the CHANGE ENGINE OIL SOON
message comes back on when the
vehicle is started, the engine oil life
system has not been reset. Repeat
the procedure.
Automatic Transmission
Fluid
It is not necessary to check the
transmission fluid level.
A transmission fluid leak is the only
reason for fluid loss. If a leak
occurs, take the vehicle to your
dealer and have it repaired as soon
as possible.
Change the fluid at the intervals
listed in Maintenance Schedule
0 312, and be sure to use the
transmission fluid listed in
Recommended Fluids and
Lubricants 0320.
