Tire Pressure Monitor
This vehicle may have a Tire
Pressure Monitor System (TPMS).
The low tire pressure warning light
alerts to a significant loss in
pressure of one of the vehicle's
tires. If the warning light comes on,
stop as soon as possible and inflate
the tires to the recommended
pressure shown on the Tire and
Loading Information label. See
Vehicle Load Limits on page 9‑12.
The warning light will remain on until
the tire pressure is corrected.
The low tire pressure warning light
may come on in cool weather when
the vehicle is first started, and then
turn off as the vehicle is driven. This
may be an early indicator that thetire pressures are getting low and
the tires need to be inflated to the
proper pressure.
The TPMS does not replace normal
monthly tire maintenance. Maintain
the correct tire pressures.
See
Tire Pressure Monitor System
on page 10‑62.

Checking Engine Oil
This vehicle has a high performance
dry sump lubrication system. This
system operates differently than a
standard engine lubrication system.
See Engine Oil on page 10‑13.
You should check the oil level only
after the engine has been
thoroughly warmed up and then shut off for at least five minutes.
This ensures that the oil level
reading obtained will be accurate.
Jump Starting the Battery
The battery is in the rear of the
vehicle. You do not need to access
the battery for jump starting. There
are remote positive (+) and negative
(−) terminals under the hood for this
purpose. See
Battery on page 10‑37
and Jump Starting on page 10‑75.
Brake Noise
Under certain weather or operating
conditions, occasional brake noise
might be heard with the vehicle's
performance braking system. This
brake system is designed for
superior fade resistance and
consistent operation using high
performance brake pads. Brake
noise is normal and does not affect
system performance.

New Vehicle Break-In
Follow these recommended
guidelines during the first 2414 km
(1500 mi) of driving this vehicle.
Parts have a break-in period and
performance will be better in the
long run.
For the first 322 km (200 mi):
.To break in new tires, drive at
moderate speeds and avoid hard
cornering for the first 322 km
(200 mi).
.New brake linings also need a
break- in period. Avoid making
hard stops during the first
322 km (200 mi). This is
recommended every time brake
linings are replaced.For the first 800 km (500 mi):
.Avoid full throttle starts and
abrupt stops.
.Do not exceed 4000 rpm.
.Avoid driving at any one
constant speed, fast or slow,
including the use of cruise
control.
.Avoid downshifting to brake or
slow the vehicle when the
engine speed will exceed
4000 rpm.
.Do not let the engine labor.
Never lug the engine in high
gear at low speeds. With a
manual transmission, shift to the
next lower gear. This rule
applies at all times, not just
during the break-in period.
For the first 2414 km (1500 mi):
.Do not participate in track
events, sport driving schools,
or similar activities during the
first 2414 km (1500 mi).
.Check engine oil with every

For customers who do not use TOP
TIER Detergent Gasoline regularly,
one bottle of Fuel System Treatment
PLUS, part number 88861013,
added to the fuel tank at every
engine oil change, can help clean
deposits from fuel injectors and
intake valves. GM Fuel System
Treatment PLUS is the only
gasoline additive recommended by
General Motors. It is available at
your dealer.
Gasolines containing oxygenates,
such as ethers and ethanol, and
reformulated gasolines might be
available in your area. We
recommend that you use these
gasolines, if they comply with the
specifications described earlier.
However, E85 (85% ethanol) and
other fuels containing more than
15% ethanol must not be used in
vehicles that were not designed for
those fuels.Notice:
This vehicle was not
designed for fuel that contains
methanol. Do not use fuel
containing methanol. It can
corrode metal parts in the fuel
system and also damage plastic
and rubber parts. That damage
would not be covered under the
vehicle warranty.
Some gasolines that are not
reformulated for low emissions can
contain an octane-enhancing
additive called
methylcyclopentadienyl manganese
tricarbonyl (MMT); ask the attendant
where you buy gasoline whether the
fuel contains MMT. We recommend
against the use of such gasolines.
Fuels containing MMT can reduce
spark plug life and affect emission
control system performance. The
malfunction indicator lamp might
turn on. If this occurs, return to your
dealer for service.Filling the Tank

10-14 Vehicle Care
Checking Engine Oil (Except
Z06, ZR1, manual transmission
Grand Sport Coupe, and 427
Convertible)
If the CHECK OIL LEVEL message
displays on the Driver Information
Center (DIC), check the engine oil
level right away. For more
information, seeEngine Oil
Messages on page 5‑39. Check the
engine oil level regularly; this is an
added reminder.
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
on page 10‑8 for the location of the
engine oil dipstick. Obtaining an accurate oil level
reading is essential:
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 the dipstick and clean it with a paper towel or cloth, then push
it back in all the way. Remove it
again, keeping the tip down, and
check the level.
When to Add Engine Oil
(Except Z06, ZR1, manual
transmission Grand Sport
Coupe, and 427 Convertible)
If the oil is below the cross-hatched
area at the tip of the dipstick, add
1 L (1 qt) of the recommended oil
and then recheck the level. See
“Selecting the Right Engine Oil” in
this section for an explanation of
what kind of oil to use. For engine
oil crankcase capacity, see
Capacities and Specifications on
page 12‑2.
See Racing or Other Competitive
Driving on page 9‑6 for additional
information on engine oil.

tank and there could be no engine
oil at all showing on the dipstick.
This is normal since the dipstick is
designed to read engine oil level
only after the engine has run long
enough to reach normal operating
temperature. Do not add engine oil
based on cold engine dipstick
readings. The engine oil level on the
dipstick will also be inaccurate if
checked while the engine is running.
1. To obtain an accurate engine oillevel reading, warm up the
engine to at least 80°C (175°F).
Cold oil will not give a correct oil
level reading.
2. Once the engine is warm, turn off the engine. Checking the oil
while the engine is running will
result in an incorrect oil level
reading.
3. Wait at least five minutes (but not more than 20 minutes) to
allow oil to drain and settle in the
engine.{WARNING
The engine oil dipstick handle
may be hot; it could burn you.
Use a towel or glove to touch the
dipstick handle.
4. Remove the dipstick from the external engine oil tank and
clean it with a lint-free paper
towel or a cloth. Re-insert the
dipstick into the external oil tank,
pushing it all the way in until it
stops.
5. Remove the dipstick from the oil tank and read the level on the
cross-hatched area. Oil levels
that fall in the cross-hatched
area are normal.
When to Add Engine Oil (Z06,
ZR1, manual transmission
Grand Sport Coupe, and 427
Convertible)
If the oil is below the cross-hatched
area at the tip of the dipstick, add
1 L (1 qt) of the recommended oil
through the oil fill cap opening in the
oil tank and then recheck the level.
See “Selecting the Right Engine Oil”
for an explanation of what kind of oil
to use. For engine oil crankcase
capacity, see Capacities and
Specifications on page 12‑2.

2. Once the oil has been drainedfrom the engine, remove the
engine oil filter and allow the oil
to drain.
3. Re-install both drain plugs and tighten them to 25 Y(18 lb ft).
4. Replace the oil filter and tighten it to 30 Y(22 lb ft). See
Maintenance Replacement Parts
on page 11‑14 for the correct
filter.
5. Oil is filled through the opening in the top of the external engine
oil tank. Remove the oil fill cap.
6. Add 9.9 L (10.5 quarts) of oil to the oil tank. See Capacities and
Specifications on page 12‑2.
7. Install the oil fill cap and insert the dipstick, if removed.
8. Start the engine and let it run at idle for at least 15 seconds. This
will circulate the fresh engine oil
through the lubrication system. 9. Shut off the engine and check
the oil level as described under
“Checking Engine Oil (Z06, ZR1,
and Grand Sport).”
Selecting the Right Engine Oil
Selecting the right engine oil
depends on both the proper oil
specification and viscosity grade.
See Recommended Fluids and
Lubricants on page 11‑12.
Specification
Use and ask for licensed engine oils
with the dexos1
®approved
certification mark. Engine oils
meeting the requirements for the
vehicle should have the dexos1
approved certification mark. This
certification mark indicates that the
oil has been approved to the dexos1
specification. Corvette recommends
Mobil 1
®engine oils that meet the
requirements of the dexos1
specification for its dry-sump
equipped engines.
Notice: Failure to use the
recommended engine oil or
equivalent can result in engine
damage not covered by the
vehicle warranty. Check with your
dealer or service provider on
whether the oil is approved to the
dexos1 specification.
Viscosity Grade
SAE 5W-30 is the best viscosity
grade for the vehicle. Do not use
other viscosity grade oils such as
SAE 10W-30, 10W-40, or 20W-50.
Cold Temperature Operation: In an
area of extreme cold, where the
temperature falls below −29°C
(−20°F), an SAE 0W-30 oil may be
used. An oil of this viscosity grade
will provide easier cold starting for
the engine at extremely low
temperatures. When selecting an oil

Black plate (19,1)Chevrolet Corvette Owner Manual - 2013 - crc2 - 11/8/12
Vehicle Care 10-19
of the appropriate viscosity grade,
always select an oil of the correct
specification. See“Specification”
earlier in this section for more
information.
Engine Oil Additives/Engine
Oil Flushes
Do not add anything to the oil. The
recommended oils with the dexos
specification and displaying the
dexos certification mark are all that
is needed for good performance and
engine protection.
Engine oil system flushes are not
recommended and could cause
engine damage not covered by the
vehicle warranty.
What to Do with Used Oil
Used engine oil contains certain
elements that can be unhealthy for
your skin and could even cause
cancer. Do not let used oil stay on
your skin for very long. Clean your
skin and nails with soap and water,
or a good hand cleaner. Wash or
properly dispose of clothing or rags containing used engine oil. See the
manufacturer's warnings about the
use and disposal of oil products.
Used oil can be a threat to the
environment. If you change your
own oil, be sure to drain all the oil
from the filter before disposal. Never
dispose of oil by putting it in the
trash or pouring it on the ground,
into sewers, or into streams or
bodies of water. Recycle it by taking
it to a place that collects used oil.
Engine Oil Life System
When to Change Engine Oil
This vehicle has a computer that
indicates when to change the
engine oil and filter. This is based
on a combination of factors which
include engine revolutions, engine
temperature, and miles driven.
Based on driving conditions, the
mileage at which an oil change is
indicated can vary considerably. For
the oil life system to work properly,
the system must be reset every time
the oil is changed.Z06, ZR1, manual transmission
Grand Sport Coupe, and 427
Convertible models have a
racetrack-ready dry sump engine
lubrication system. This
high-performance system operates
differently than a standard engine
lubrication system and requires a
special procedure when changing
the engine oil and filter. See
Engine
Oil on page 10‑13.
When the system has calculated
that oil life has been diminished, it
indicates that an oil change is
necessary. A CHANGE ENGINE
OIL message comes on. Change
the oil as soon as possible within
the next 1 000 km (600 mi). It is
possible that, if driving under the
best conditions, the oil life system
might indicate that an oil change is
not necessary for up to a year. The
engine oil and filter must be
changed at least once a year and,
at this time, the system must be
reset. Your dealer has trained
service people who will perform this
work and reset the system. It is also

Black plate (20,1)Chevrolet Corvette Owner Manual - 2013 - crc2 - 11/8/12
10-20 Vehicle Care
important to check the oil regularly
over the course of an oil drain
interval and keep it at the proper
level.
If the system is ever reset
accidentally, the oil must be
changed at 5 000 km (3,000 mi)
since the last oil change.
Remember to reset the oil life
system whenever the oil is changed.
How to Reset the Engine Oil
Life System
Reset the system whenever the
engine oil is changed so that the
system can calculate the next
engine oil change. To reset the
system:
1. Press the TRIP button so theOIL LIFE percentage is
displayed.
2. Press RESET and hold for two seconds. OIL LIFE
REMAINING 100% will appear. If the CHANGE ENGINE OIL
message comes back on when the
vehicle is started, the engine oil life
system has not reset. Repeat the
procedure.
Automatic Transmission
Fluid
How to Check Automatic
Transmission Fluid
It is not necessary to check the
transmission fluid level.
A transmission fluid leak is the only
reason for fluid loss. If a leak
occurs, take the vehicle to the
dealer and have it repaired as soon
as possible.
The vehicle is not equipped with a
transmission fluid level dipstick.
There is a special procedure for
checking and changing the
transmission fluid. Because this
procedure is difficult, this should be
done at the dealer. Contact the
dealer for additional information or
the procedure can be found in the service manual. To purchase a
service manual, see
Service
Publications Ordering Information
on page 13‑16.
Notice: Use of the incorrect
automatic transmission fluid may
damage the vehicle, and the
damages may not be covered by
the vehicle warranty. Always use
the automatic transmission fluid
listed in Recommended Fluids
and Lubricants on page 11‑12.
Change the fluid and filter at the
intervals listed in Maintenance
Schedule on page 11‑3, and be sure
to use the fluid listed in
Recommended Fluids and
Lubricants on page 11‑12.
