2021 CHEVROLET BOLT EV brake fluid

Chevrolet Bolt EV Owner Manual (GMNA-Localizing-U.S./Canada-
14637856) - 2021 - CRC - 10/2/20
204 Vehicle Care
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 Schedule0253.
What to Add
Use only GM approved DOT 4 brake fluid
from a clean, sealed container. See
Recommended Fluids and Lubricants 0258.
{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.
Caution
If brake fluid is spilled on the vehicle's
painted surfaces, the paint finish can be
damaged. Immediately wash off any
painted surface.
Battery - North America
The original equipment battery is
maintenance free. Do not remove the cap
and do not add fluid.
This vehicle has a high voltage battery and
a standard 12-volt battery.
{Warning
Damage to the high voltage battery or
high voltage system can create a risk of
electric shock, overheating, or fire.
If the vehicle is damaged from a
moderate to severe crash, flood, fire,
or other event, the vehicle should be
inspected as soon as possible. Until the
vehicle has been inspected, store it
outside at least 15 m (50 ft) from any
structure or anything that can burn.
Ventilate the vehicle by opening a
window or a door.
Contact Customer Assistance as soon as
possible to determine whether an
inspection is needed. See Customer
Assistance Offices 0264. If the vehicle is in a crash, the sensing
system may shut down the high voltage
system. When this occurs, the high voltage
battery is disconnected and the vehicle will
not start. The SERVICE VEHICLE SOON
message in the Driver Information Center
(DIC) will be displayed. Before the vehicle
can be operated again, it must be serviced
at your dealer.
See
“If a Crash Occurs” underCollision
Damage Repair 0268 for additional
information. If an airbag has inflated, see
What Will You See after an Airbag Inflates?
0 42.
Only a trained service technician with
the proper knowledge and tools should
inspect, test, or replace the high voltage
battery. See your dealer if either the 12-volt
or high voltage battery needs service. The
dealer has information on how to recycle
the high voltage battery. There is also
information available at
http://www.recyclemybattery.com.
Keep the vehicle plugged in, even when fully
charged, to keep the high voltage battery
temperature ready for the next drive. This is
important when outside temperatures are
extremely hot or cold.

General Information
Your vehicle is an important investment.
This section describes the required
maintenance for the vehicle. Follow this
schedule to help protect against major repair
expenses resulting from neglect or
inadequate maintenance. It may also help to
maintain the value of the vehicle if it is
sold. It is the responsibility of the owner to
have all required maintenance performed.
Your dealer has trained technicians who can
perform required maintenance using genuine
replacement parts. They have up-to-date
tools and equipment for fast and accurate
diagnostics. Many dealers have extended
evening and Saturday hours, courtesy
transportation, and online scheduling to
assist with service needs.
Your dealer recognizes the importance of
providing competitively priced maintenance
and repair services. With trained technicians,
the dealer is the place for routine
maintenance such as tire rotations and
additional maintenance items like tires,
brakes, batteries, and wiper blades.
Caution
Damage caused by improper maintenance
can lead to costly repairs and may not be
covered by the vehicle warranty.
Maintenance intervals, checks,
inspections, recommended fluids, and
lubricants are important to keep the
vehicle in good working condition.
Do not have chemical flushes that are not
approved by GM performed on the
vehicle. The use of flushes, solvents,
cleaners, or lubricants that are not
approved by GM could damage the
vehicle, requiring expensive repairs that
are not covered by the vehicle warranty.
The Tire Rotation and Required Services are
the responsibility of the vehicle owner. It is
recommended to have your dealer perform
these services every 12 000 km/7,500 mi.
Proper vehicle maintenance helps to keep

256 Service and Maintenance
services may be required. It is recommended
that your dealer perform these services—
their trained dealer technicians know your
vehicle best. Your dealer can also perform a
thorough assessment with a multi-point
inspection to recommend when your vehicle
may need attention. The following list is
intended to explain the services and
conditions to look for that may indicate
services are required.
Battery
The battery supplies power to operate any
additional electrical accessories.
.To avoid break-down or failure, maintain
a battery with full power.
.Trained dealer technicians have the
diagnostic equipment to test the battery
and ensure that the connections and
cables are corrosion-free.
Brakes
Brakes stop the vehicle and are crucial to
safe driving.
.Signs of brake wear may include chirping,
grinding, or squealing noises, or difficulty
stopping.
.Trained dealer technicians have access to
tools and equipment to inspect the brakes
and recommend quality parts engineered
for the vehicle.
Fluids
Proper fluid levels and approved fluids
protect the vehicle’s systems and
components. See Recommended Fluids and
Lubricants 0258 for GM approved fluids.
.Keep the windshield washer fluid reservoir
filled.
.Instrument cluster lights may come on to
indicate that fluids may be low and need
to be filled.
Hoses
Hoses transport fluids and should be
regularly inspected to ensure that there are
no cracks or leaks. With a multi-point
inspection, your dealer can inspect the hoses
and advise if replacement is needed. Lamps
Properly working headlamps, taillamps, and
brake lamps are important to see and be
seen on the road.
.Signs that the headlamps need attention
include dimming, failure to light, cracking,
or damage. The brake lamps need to be
checked periodically to ensure that they
light when braking.
.With a multi-point inspection, your dealer
can check the lamps and note any
concerns.
Shocks and Struts
Shocks and struts help aid in control for a
smoother ride.
.Signs of wear may include steering wheel
vibration, bounce/sway while braking,
longer stopping distance, or uneven
tire wear.
.As part of the multi-point inspection,
trained dealer technicians can visually
inspect the shocks and struts for signs of
leaking, blown seals, or damage, and can
advise when service is needed.
