Instruments and Controls 97If the ignition is turned off while the
wipers are performing wipes due to
windshield washing or Rainsense,
the wipers continue to run until they
reach the base of the windshield.
Rainsense If equipped with Rainsense, a
sensor located near the top center
of the windshield detects the
amount of water on the windshield
and automatically controls the
frequency of the windshield wiper.
When Rainsense is enabled, the
normal intermittent control operates
as a sensitivity control.
Keep this area of the windshield
clear of debris to allow for best
system performance. AUTO : Move the windshield wiper
lever to AUTO. Turn the band on the
wiper lever to adjust the sensitivity.
.
Turn the band up for more
sensitivity to moisture.
.
Turn the band down for less
sensitivity to moisture.
.
Move the windshield wiper lever
out of the AUTO position to
deactivate Rainsense.
To enable or disable this feature,
see “ Rainsense Wipers ” under
Vehicle Personalization 0 133 .
Wiper Arm Assembly Protection
When using an automatic car wash,
move the windshield wiper lever to
OFF. This disables the automatic
Rainsense windshield wipers and/or
manual windshield wipers.
With Rainsense, if the transmission
is in N (Neutral) and the vehicle
speed is very slow, the wipers will
automatically stop at the base of the
windshield. The wiper operations return to
normal when the transmission is no
longer in N (Neutral) or the vehicle
speed has increased.
Windshield Washer
f : Pull the windshield wiper
lever toward you to spray windshield
washer fluid and activate the wipers.
The wipers will continue until the
lever is released or the maximum
wash time is reached. When the
lever is released, additional wipes
may occur depending on how long
the windshield washer had been
activated. See Washer Fluid 0 248
for information on filling the
windshield washer fluid reservoir.
Rear Window Wiper/
Washer The ignition must be on or in ACC/
ACCESSORY to operate the rear
window wiper/washer.

The headlamps must be on in order
to use the headlamp washers. If the
headlamps are not on, only the
windshield will be washed.
Pull the wiper lever toward you and
hold briefly to activate. The
headlamp washers will spray once, pause, and spray again. The
headlamp washers will spray again
after five windshield wash cycles.
To refill the windshield washer fluid,
see Washer Fluid 0 248 .
Compass The vehicle may have a compass
display on the Driver Information
Center (DIC). The compass receives
its heading and other information
from the Global Positioning
System (GPS) antenna, StabiliTrak/
Electronic Stability Control (ESC),
and vehicle speed information.
The compass system is designed to
operate for a certain number of
miles or degrees of turn before
needing a signal from the GPS
satellites. When the compass
display shows CAL, drive the
vehicle for a short distance in an
open area where it can receive a
GPS signal. The compass system
will automatically determine when a
GPS signal is restored and provide
a heading again.

Driving and Operating 167.
Keep windshield wiping
equipment in good shape.
.
Keep the windshield washer fluid
reservoir filled.
.
Have good tires with proper
tread depth. See Tires 0 265 .
.
Turn off cruise control.
Hill and Mountain Roads Driving on steep hills or through
mountains is different than driving
on flat or rolling terrain. Tips include:
.
Keep the vehicle serviced and in
good shape.
.
Check all fluid levels and brakes,
tires, cooling system, and
transmission.
.
Shift to a lower gear when going
down steep or long hills.
{ Warning
Using the brakes to slow the
vehicle on a long downhill slope
can cause brake overheating, can
(Continued) Warning (Continued) reduce brake performance, and
could result in a loss of braking.
Shift the transmission to a lower
gear to let the engine assist the
brakes on a steep downhill slope.
{ WarningCoasting downhill in N (Neutral)
or with the ignition off is
dangerous. This can cause
overheating of the brakes and
loss of steering assist. Always
have the engine running and the
vehicle in gear.
.
Drive at speeds that keep the
vehicle in its own lane. Do not
swing wide or cross the
center line.
.
Be alert on top of hills;
something could be in your lane
(e.g., stalled car, crash). .
Pay attention to special road
signs (e.g., falling rocks area,
winding roads, long grades,
passing or no-passing zones)
and take appropriate action.
Winter Driving Driving on Snow or Ice Snow or ice between the tires and
the road creates less traction or
grip, so drive carefully. Wet ice can
occur at about 0 °C (32 °F) when
freezing rain begins to fall. Avoid
driving on wet ice or in freezing rain
until roads can be treated.
For Slippery Road Driving:
.
Accelerate gently. Accelerating
too quickly causes the wheels to
spin and makes the surface
under the tires slick.
.
Turn on Traction Control. See
Traction Control/Electronic
Stability Control 0 188 .
.
The Antilock Brake System
(ABS) improves vehicle stability
during hard stops, but the
brakes should be applied sooner

Engine Oil To ensure proper engine
performance and long life, careful
attention must be paid to engine oil.
Following these simple, but
important steps will help protect
your investment: .
Use engine oil approved to the
proper specification and of the
proper viscosity grade. See
“ Selecting the Right Engine Oil ”
in this section.
.
Check the engine oil level
regularly and maintain the
proper oil level. See “ Checking
Engine Oil ” and “ When to Add
Engine Oil ” in this section.
.
Change the engine oil at the
appropriate time. See Engine Oil
Life System 0 239 .
.
Always dispose of engine oil
properly. See “ What to Do with
Used Oil ” in this section.
Checking Engine Oil Check the engine oil level regularly,
every 650 km (400 mi), especially
prior to a long trip. The engine oil
dipstick handle is a loop. See
Engine Compartment Overview
0 234 for the location.{ WarningThe engine oil dipstick handle
may be hot; it could burn you.
Use a towel or glove to touch the
dipstick handle.
If a low oil Driver Information Center
(DIC) message displays, check the
oil level.
Follow these guidelines:
.
To get an accurate reading, park
the vehicle on level ground.
Check the engine oil level after
the engine has been off for at
least two hours. Checking the
engine oil level on steep grades
or too soon after engine shutoff
can result in incorrect readings.
Accuracy improves when
checking a cold engine prior to
starting. Remove the dipstick
and check the level.
.
If unable to wait two hours, the
engine must be off for at least
15 minutes if the engine is
warm, or at least 30 minutes if

Buick Envision Owner Manual (GMNA-Localizing-U.S./Canada/Mexico-
13555857) - 2020 - CRC - 3/12/19
248 Vehicle Care If the overheat warning is displayed
with no sign of steam:
1. Turn the air conditioning off.
2. Turn the heater on to the
highest temperature and to the
highest fan speed. Open the
windows as necessary.
3. When it is safe to do so, pull off
the road, shift to P (Park) or
N (Neutral), and let the
engine idle.
If the engine coolant temperature
gauge is no longer in the overheat
zone, the vehicle can be driven.
Continue to drive the vehicle slowly
for about 10 minutes. Keep a safe
vehicle distance from the vehicle in
front. If the warning does not come
back on, continue to drive normally
and have the cooling system
checked for proper fill and function.
If the warning continues, pull over,
stop, and park the vehicle
right away. If there is no sign of steam, idle the
engine for three minutes while
parked. If the warning is still
displayed, turn off the engine until it
cools down.
Washer Fluid What to Use When the vehicle needs windshield
washer fluid, be sure to read the
manufacturer's instructions before
use. If operating the vehicle in an
area where the temperature may fall
below freezing, use a fluid that has
sufficient protection against
freezing.
Adding Washer Fluid Open the cap with the washer
symbol on it. Add washer fluid until
the tank is full. See Engine
Compartment Overview 0 234 for
reservoir location.
Caution .
Do not use washer fluid that
contains any type of water
repellent coating. This can
cause the wiper blades to
chatter or skip.
.
Do not use engine coolant
(antifreeze) in the
windshield washer. It can
damage the windshield
washer system and paint.
.
Do not mix water with
ready-to-use washer fluid.
Water can cause the
solution to freeze and
damage the washer fluid
tank and other parts of the
washer system.
