Vehicle Care 249
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 0 289.
What to Add
Use only GM approved DOT 4 brake fluid
from a clean, sealed container. See
Recommended Fluids and Lubricants 0 291.
{
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
This vehicle has a high voltage battery and
a standard 12-volt battery.
See your Cadillac Service Centre if either the
12-volt or high voltage battery needs service.
12-Volt Battery
The original equipment battery is
maintenance free. Do not remove the cap
and do not add fluid.
Do not disconnect the 12-volt battery during
storage.
Refer to the replacement number shown on
the original battery label when a new 12-volt
battery is needed. The vehicle has an
Absorbent Glass Mat (AGM)/Valve regulated
lead acid battery (VRLA) 12-volt battery.
Installation of a standard 12-volt battery will
result in reduced 12-volt battery life.
Some 12-volt chargers have an AGM battery
setting. This setting limits the charge
voltage to 14.8 volts and helps extend the
battery life. If available, use the AGM
setting when charging the battery.
High Voltage Battery
Only a trained service technician should
inspect, test, or replace the high voltage
battery. The Cadillac Service Centre has
information on how to recycle the high
voltage battery. There is also information
available at https://
www.recyclemybattery.com.
{
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.
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 Centre
(DIC) will display. Before the vehicle can
operate again, it must be serviced at your
Cadillac Service Centre.
