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 0256.
. Always dispose of engine oil
properly. See “What to Do with
Used Oil” in this section.
Checking Engine Oil
It is a good idea to check the engine
oil level at each fuel fill. In order to
get an accurate reading, the vehicle must be on level ground. The
engine oil dipstick handle is a loop.
See
Engine Compartment Overview
0 247 for the location of the engine
oil dipstick.
1. If the engine has been running recently, turn off the engine and
allow several minutes for the oil
to drain back into the oil pan.
Checking the oil level too soon
after engine shutoff will not
provide an accurate oil level
reading.
{Warning
The engine oil dipstick handle
may be hot; it could burn you.
Use a towel or glove to touch the
dipstick handle.
2. Pull out the dipstick and wipe it with a clean paper towel or
cloth, then push it back in all
the way. Remove it again,
keeping the tip down, and
check the level.

268 Vehicle Care
There are only two reasons why the
brake fluid level in the reservoir may
go down:
.Normal brake lining wear. When
new linings are installed, the
fluid level goes back up.
. A fluid leak in the brake
hydraulic system. Have the
brake hydraulic system fixed.
With a leak, the brakes will not
work well.
Always clean the brake fluid
reservoir cap and the area around
the cap before removing it.
Do not top off the brake fluid.
Adding fluid does not correct a leak.
If fluid is added when the linings are
worn, there will be too much fluid
when new brake linings are
installed. Add or remove fluid, as
necessary, only when work is done
on the brake hydraulic system.{Warning
If too much brake fluid is added, it
can spill on the engine and burn,
if the engine is hot enough. You
or others could be burned, and
the vehicle could be damaged.
Add brake fluid only when work is
done on the brake hydraulic
system.
When the brake fluid falls to a low
level, the brake warning light comes
on. See Brake System Warning
Light 0120.
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 0323.
What to Add
Use only GM approved DOT 3
brake fluid from a clean, sealed
container. See Recommended
Fluids and Lubricants 0327.
{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
The original equipment battery is
maintenance free. Do not remove
the cap and do not add fluid.
The battery is in the trunk, behind
the trim panel, on the driver side of
the vehicle. Refer to the

Cadillac ATS/ATS-V Owner Manual (GMNA-Localizing-MidEast-9369639) -
2016 - crc - 12/9/15
Vehicle Care 269
replacement number shown on the
original battery label when a new
battery is needed.
{Warning
Do not use a match or flame near
a vehicle's battery. If you need
more light, use a flashlight.
Do not smoke near a vehicle's
battery.
When working around a vehicle’s
battery, shield your eyes with
protective glasses.(Continued)
Warning (Continued)
Keep children away from vehicle
batteries.
{Warning
Batteries have acid that can burn
you and gas that can explode.
You can be hurt badly if you are
not careful.
Follow instructions carefully when
working around a battery.
Battery posts, terminals and
related accessories contain lead
and lead compounds which can
cause cancer and reproductive
harm. Wash hands after handling.
After a power loss, such as
disconnecting the battery or
removing the maxi fuses in the
power distribution fuse block, the
following steps must be performed to calibrate the electronic throttle
control. If this is not done, the
engine will not run properly.
1. Turn the ignition on but do not start the engine.
2. Leave the ignition on for at least three minutes so that the
electronic throttle control will
cycle and relearn its home
position.
3. Turn the ignition off.
4. Start and run the engine for at least 30 seconds.
Vehicle Storage
Infrequent Usage: Remove the
black, negative (−) cable from the
battery to keep the battery from
running down.
Extended Storage: Remove the
black, negative (−) cable from the
battery or use a battery trickle
charger.

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.
{Warning
.Poorly maintained and
improperly used tires are
dangerous.
.Overloading the tires can
cause overheating as a
result of too much
flexing. There could be a
blowout and a serious
crash. See Vehicle Load
Limits 0187.
(Continued)
Warning (Continued)
.Underinflated tires pose
the same danger as
overloaded tires. The
resulting crash could
cause serious injury.
Check all tires frequently
to maintain the
recommended pressure.
Tire pressure should be
checked when the tires
are cold.
.Overinflated tires are
more likely to be cut,
punctured, or broken by
a sudden impact —such
as when hitting a pothole.
Keep tires at the
recommended pressure.
.Worn or old tires can
cause a crash. If the
tread is badly worn,
replace them.

Jump Starting
For more information about the
vehicle battery, see Battery0268.
For the LF4 only, there is an
optional low mass battery that can
be used for Track events. If the
vehicle has the low mass battery
installed and the battery has a low
State of Charge (SOC), the vehicle
can be jump started the say way as
if the regular battery was in the
vehicle using the following
procedure. For more information on
the low mass battery, see Battery
0 268 andTrack Events and
Competitive Driving 0179.
If the battery has run down, try to
use another vehicle and some
jumper cables to start your vehicle.
Be sure to use the following steps to
do it safely.

{Warning
Batteries can hurt you. They can
be dangerous because:. They contain acid that can
burn you.
. They contain gas that can
explode or ignite.
. They contain enough
electricity to burn you.
If you do not follow these steps
exactly, some or all of these
things can hurt you.
Caution
Ignoring these steps could result
in costly damage to the vehicle
that would not be covered by the
vehicle warranty. Trying to start
the vehicle by pushing or pulling it
will not work, and it could damage
the vehicle.
1. Good Battery Positive Post
2. Good Battery Negative Post
3. Discharged Battery Positive Post
4. Discharged Battery Negative Grounding Point
The jump start positive post (1) and
negative post (2) are on the battery
of the vehicle providing the jump
start.
The jump start positive post (3) and
the negative grounding point (4) for
the discharged battery are on the
passenger side of the vehicle. The positive jump start connection
for the discharged battery is under a
red cover. Remove the cover to
expose the terminal.
1. Check the other vehicle. It must have a 12-volt battery
with a negative ground system.
Caution
If the other vehicle does not have
a 12-volt system with a negative
ground, both vehicles can be
damaged. Only use a vehicle that
has a 12-volt system with a
negative ground for jump starting.
2. Position the two vehicles so that they are not touching.
3. Set the parking brake firmly and put the shift lever in
P (Park) with an automatic
transmission, or Neutral with a
manual transmission. See
Shifting Into Park 0195.
