192 Driving and Operating
Stopping the Engine/OFF (No Indicator
Lights) :When the vehicle is stopped, press
ENGINE START/STOP once to turn the
engine off.
If the vehicle is in P (Park), the vehicle will
turn off, and Retained Accessory Power
(RAP) will remain active. See Retained
Accessory Power (RAP) 0195.
When the vehicle is stopped, press ENGINE
START/STOP to turn off the vehicle. The
transmission will shift to P (Park)
automatically.
Do not turn the engine off when the vehicle
is moving. This will cause a loss of power
assist in the brake and steering systems and
disable the airbags.
If the vehicle must be shut off in an
emergency: 1. Brake using a firm and steady pressure. Do not pump the brakes repeatedly. This
may deplete power assist, requiring
increased brake pedal force.
2. Shift the vehicle to N (Neutral). This can be done while the vehicle is moving.
After shifting to N (Neutral), firmly apply
the brakes and steer the vehicle to a
safe location. 3. Come to a complete stop, shift to
P (Park), and turn the vehicle off. The
vehicle must be in P (Park) to turn the
vehicle off.
4. Set the parking brake. See Electric
Parking Brake 0202.
{Warning
Turning off the vehicle while moving may
cause loss of power assist in the brake
and steering systems and disable the
airbags. While driving, only shut the
vehicle off in an emergency.
If the vehicle cannot be pulled over, and
must be shut off while driving, press and
hold ENGINE START/STOP for longer than
two seconds, or press twice in five seconds.
Accessory (Amber Indicator Light) : This
mode allows some electrical accessories to
be used when the engine is off.
With the vehicle off, pressing the button
one time without the brake pedal applied
will place the vehicle in accessory.
The vehicle will switch from accessory to
OFF after five minutes to prevent battery
rundown. ON/RUN/START (Green Indicator Light) :
This
mode is for driving and starting. With the
vehicle off, and the brake pedal applied,
pressing the button once will place the
vehicle in ON/RUN/START. Once engine
cranking begins, release the button. Engine
cranking will continue until the engine
starts. See Starting the Engine 0192. The
vehicle will then remain in ON/RUN.
Service Mode
This power mode is available for service and
diagnostics, and to verify the proper
operation of the malfunction indicator lamp
as may be required for emission inspection
purposes. With the vehicle off, and the
brake pedal not applied, pressing and
holding ENGINE START/STOP for more than
five seconds will place the vehicle in Service
Mode. The instruments and audio systems
will operate as they do in ON/RUN, but the
vehicle will not be able to be driven. The
engine will not start in Service Mode. Press
the button again to turn the vehicle off.
Starting the Engine

Driving and Operating 201
Manual Mode
Tap ShiftCaution
Driving with the engine at a high rpm
without upshifting while using Tap Shift,
could damage the vehicle. Always upshift
when necessary while using Tap Shift.
Vehicles with Tap Shift have controls on the
back of the steering wheel to manually shift
the automatic transmission. Permanent Tap Shift Mode
To enter Permanent Tap Shift Mode:
1. With the vehicle in D (Drive), press the M (Manual Mode) button.
2. Pull the steering wheel control toward you to shift. Pull the left control to
downshift, and the right control to
upshift.
To exit Permanent Tap Shift Mode, pull the
D (Drive) switch on the center console.
Temporary Tap Manual Shift Mode
To enter Temporary Tap Shift Mode: 1. With the transmission in D (Drive) and not in Permanent Tap Shift Mode, the
Tap Shift controls will activate a
Temporary Tap Shift Mode, allowing the
transmission to be manually shifted.
2. To deactivate, hold the right control briefly. Automatic shifts return after no
manual shifts have been done for seven
to 10 seconds.
While using Tap Shift, the vehicle will have
firmer, quicker shifting. This can be used for
sport driving or when climbing or
descending hills, to stay in gear longer,
or to downshift for more power or engine
braking. The transmission will only allow shifting
into gears appropriate for the vehicle speed
and engine revolutions per minute (rpm).
If shifting is prevented for any reason, the
M or D will flash in the instrument cluster.
The transmission will not automatically shift
to the next higher gear if the engine rpm is
too high. It will only automatically shift to
the next lower gear if the engine rpm is
much too low.
Drive Systems
All-Wheel Drive
Vehicles with this feature can operate in
All-Wheel Drive (AWD) Mode. When the
AWD feature is active, the system transfers
engine power, if required, to all four wheels.
The system is fully automatic and adjusts to
road conditions for improved traction and
control. In FWD Mode engine power is
transferred to the front wheels only, and
the AWD feature is off.
The AWD feature is automatically activated
when certain modes are selected using the
Driver Mode Control switch. When an AWD
mode change is requested the light will
flash briefly while the system is engaging
and the AWD light will be displayed when

Buick Envision Owner Manual (GMNA-Localizing-U.S./Canada/Mexico-

202 Driving and Operating
the system is active. When a non-AWD
Mode is selected, the light will flash briefly
while the system disengages and a 2WD
light will be displayed when the AWD
system is off. SeeDriver Mode Control
0 208.
When a compact spare tire is installed on an
AWD vehicle, the system will automatically
detect the compact spare and reduce AWD
performance to protect the system. To
restore 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 0300.
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 0100.
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) can always
be applied, even if the vehicle is off. In case
of insufficient electrical power, the EPB
cannot be applied or released. To prevent
draining the battery, avoid unnecessary
repeated cycles of the EPB.
The system has a red parking brake status
light and an amber service parking brake
warning light. See Electric Parking Brake
Light 0100 and
Service Electric Parking Brake Light 0100.
There are also parking brake-related Driver
Information Center (DIC) messages.

Wheels and Tires
Tires
Every new GM vehicle has high-quality
tires made by a leading tire
manufacturer. See the warranty manual
for information regarding the tire
warranty and where to get service. For
additional information refer to the tire
manufacturer.

Vehicle Care 307
Caution
Using petroleum-based tire dressing
products on the vehicle may damage the
paint finish and/or tires. When applying a
tire dressing, always wipe off any
overspray from all painted surfaces on
the vehicle.
Wheels and Wheel Trim
Use a soft, clean cloth with mild soap and
water to clean the wheels. After rinsing
thoroughly with clean water, dry with a
soft, clean towel. A wax may then be
applied.
Caution
Chrome wheels and chrome wheel trim
may be damaged if the vehicle is not
washed after driving on roads that have
been sprayed with magnesium chloride or
calcium chloride. These are used on roads
for conditions such as dust and ice.
Always wash the chrome with soap and
water after exposure.
Caution
To avoid surface damage on wheels and
wheel trim, do not use strong soaps,
chemicals, abrasive polishes, cleaners,
or brushes. Use only GM approved
cleaners. Do not drive the vehicle through
an automatic car wash that uses silicon
carbide tire/wheel cleaning brushes.
Damage could occur and the repairs
would not be covered by the vehicle
warranty.
Brake System
Visually inspect brake lines and hoses for
proper hook-up, binding, leaks, cracks,
chafing, etc. Inspect disc brake pads for wear
and rotors for surface condition. Inspect all
other brake parts.
Steering, Suspension, and Chassis
Components
Visually inspect steering, suspension, and
chassis components for damaged, loose,
or missing parts or signs of wear at least
once a year.
Inspect power steering for proper
attachment, connections, binding, leaks,
cracks, chafing, etc.Visually check constant velocity joint boots
and axle seals for leaks.
Body Component Lubrication
Lubricate all key lock cylinders, hood hinges,
liftgate hinges, and the steel fuel door
hinge, unless the components are plastic.
Applying silicone grease on weatherstrips
with a clean cloth will make them last
longer, seal better, and not stick or squeak.
Underbody Maintenance
At least twice a year, spring and fall, use
plain water to flush any corrosive materials
from the underbody. Take care to
thoroughly clean any areas where mud and
other debris can collect.
Do not directly power wash the transfer
case and/or front/rear axle output seals.
High pressure water can overcome the seals
and contaminate the fluid. Contaminated
fluid will decrease the life of the transfer
case and/or axles and should be replaced.
Sheet Metal Damage
If the vehicle is damaged and requires sheet
metal repair or replacement, make sure the
body repair shop applies anti-corrosion
material to parts repaired or replaced to
restore corrosion protection.
