history and the amount of fuel
remaining in the fuel tank.
Oil Life :Shows an estimate of
the oil's remaining useful life.
If REMAINING OIL LIFE 99% is
displayed, that means 99% of
the current oil life remains.
When the remaining oil life is
low, the CHANGE ENGINE OIL
SOON message will appear on
the display. The oil should be
changed as soon as possible.
See Engine Oil 0383. In
addition to the engine oil life
system monitoring the oil life,
additional maintenance is
recommended. See
Maintenance Schedule 0471.
The Oil Life display must be
reset after each oil change.
It will not reset itself. Do not
reset the Oil Life display
accidentally at any time other
than when the oil has just
been changed. It cannot be
reset accurately until the next
oil change. See Engine Oil Life

Messages will display based
on the engine air filter life and
the state of the system. When
the REPLACE AT NEXT OIL
CHANGE message displays,
the engine air filter should be
replaced at the time of the
next oil change. When the

Caution
During a first time track or
racing event, high axle
temperatures can occur.
Damage could be caused to
the axle and would not be
covered by the vehicle
warranty. Do not drive as
long or as fast the first time
the vehicle is driven on the
track or raced.
.The axle lubricant should be
replaced with new lubricant.
.On vehicles without a
differential cooler, additional
cooling capacity is required
for continuous competitive
driving. The V-Series
Blackwing has a differential
cooler, so no additional
cooling capacity is
necessary.
Engine OilCaution
If the vehicle is used for
track events and
competitive driving, the
engine may use more oil
than it would with normal
use. Low oil levels can
damage the engine. Check
the oil level often and
maintain the proper level.
See Engine Oil 0383.
Check the oil level often during
track events and competitive
driving, and keep the oil level
at or near the upper mark. See
“Checking the Engine Oil" in
Engine Oil 0383.
Fuel
Use premium unleaded
gasoline with a posted octane
rating of 93 at a track event.
Unleaded gasoline with a
posted octane rating of 91 may be used, but
performance will be degraded.
See Prohibited Fuels
0361.
Automatic or Manual
Transmission Fluid
Have the transmission fluid
set to the track specific oil
level prior to track usage.
Transmission fluid should be
changed after every 15 hours
of track usage. Any
transmission level set or
change should be performed
at the dealer.
Brakes
Battery Disconnect
Disconnect the battery before
servicing the hydraulic brake
system. It is critical to
disconnect the battery before
bleeding the system, replacing
the pads, or any other work.
The battery must be
disconnected to prevent the
brake master cylinder from
pressurizing the hydraulic
system during its automated

TOP TIER Detergent Gasoline
is highly recommended for use
with your vehicle. If your
country does not have TOP
TIER Detergent Gasoline, add
ACDelco Fuel System
Treatment Plus−Gasoline to
the vehicle’s gasoline fuel tank
at every oil change or
15 000 km (9,000 mi),
whichever occurs first. TOP
TIER Detergent Gasoline and
ACDelco Fuel System
Treatment Plus−Gasoline will
help keep your vehicle’s
engine fuel deposit free and
performing optimally.
Filling the Tank
An arrow on the fuel gauge
indicates which side of the
vehicle the fuel door is on. See
Fuel Gauge0120.
{Warning
Fuel vapors and fuel fires
burn violently and can cause
injury or death.
Follow these guidelines to
help avoid injuries to you
and others:
.Read and follow all the
instructions on the fuel
pump island.
.Turn off the engine when
refueling.
.Keep sparks, flames, and
smoking materials away
from fuel.
.Do not leave the fuel
pump unattended.
.Avoid using electronic
devices while refueling.
.Do not re-enter the
vehicle while pumping fuel.
.Keep children away from
the fuel pump and never
let children pump fuel.
(Continued)
Warning (Continued)
.Before touching the fill
nozzle, touch a metallic
object to discharge static
electricity from your body.
.Fuel can spray out if the
fill nozzle is inserted too
quickly. This spray can
happen if the tank is
nearly full, and is more
likely in hot weather. Insert
the fill nozzle slowly and
wait for any hiss noise to
stop before beginning to
flow fuel.
If equipped, the fuel door
unlocks when the vehicle
doors are unlocked. See
Remote Key Operation 09.

Driving
Characteristics and
Towing Tips
{Warning
You can lose control when
towing a trailer if the correct
equipment is not used or the
vehicle is not driven
properly. For example, if the
trailer is too heavy or the
trailer brakes are
inadequate for the load, the
vehicle may not stop as
expected. You and others
could be seriously injured.
The vehicle may also be
damaged, and the repairs
would not be covered by the
vehicle warranty. Pull a
trailer only if all the steps in
this section have been
followed. Ask your dealer for
advice and information
about towing a trailer with
the vehicle.
Driving with a Trailer
Trailering is different than just
driving the vehicle by itself.
Trailering means changes in
handling, acceleration, braking,
durability, and fuel economy.
Successful, safe trailering
takes correct equipment, and
it has to be used properly.
The following information has
many time-tested, important
trailering tips and safety rules.
Many of these are important
for your safety and that of
your passengers. Read this
section carefully before pulling
a trailer.
When towing a trailer:
.Become familiar with, and
follow all state and local laws
that apply to trailer towing.
These requirements vary
from state to state.
.State laws may require the
use of extended side view
mirrors. If your visibility is
limited or restricted whiletowing, install extended side
view mirrors on your vehicle,
even if not required.
.Do not tow a trailer during
the first 800 km (500 mi) of
vehicle use to prevent
damage to the engine, axle,
or other parts.
.Perform the first oil change
before heavy towing.
.Do not drive over 800 km/h
(50 mph) and do not make
starts at full throttle during
the first 800 km (500 mi) of
trailer towing.
.Tow in D (Drive). If the
transmission downshifts too
often, a lower gear may be
selected using Manual Mode.
See Manual Mode
0282.
If equipped, the following
driver assistance features
should be turned off when
towing a trailer:
.Adaptive Cruise
Control (ACC)
.Super Cruise Control
.Park Assist

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 0386.
.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
Overview0378 for the
location.
{Warning
The 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
