1. You can remove the coolant high fill reservoir
pressure cap when the cooling system, including the
coolant high fill reservoir pressure cap and upper
radiator hose, is no longer hot. Turn the pressure cap
slowly to the left until it first stops. (Don’t press
down while turning the pressure cap.)

hiss, wait for that to stop. A hiss means
there is still

neck until the level reaches the base of the filler
neck.

If a Tire Goes Flat
It’s unusual for a tire to “blow out” while you’re driving,
especially if you maintain your tires properly. If air goes
out of a tire, it’s much more likely to leak out slowly.
But if you should ever have
a “blowout,” here are a few
tips about what to expect and what
to do:
If a front tire fails, the flat tire will create a drag that
pulls the vehicle toward that side. Take your foot off the
accelerator pedal and grip the steering wheel firmly.
Steer to maintain lane position, then gently brake to a
stop well out of the traffic lane.
A rear blowout, particularly on a curve, acts much like a
skid and may require the same correction you’d use in a
skid. In any rear blowout, remove your foot from the
accelerator pedal. Get the vehicle under control by
steering the way you want the vehicle to
go. It may be
very bumpy and noisy, but you can still steer. Gently
brake to a stop, well off the road if possible.
If a tire goes flat, the next part shows how to use your
jacking equipment to change a flat tire safely. If your
vehicle has Extended Mobility Tires (tires with “EMT”
molded on the sidewalls), see “Extended Mobility Tires”
in the Index.

only those oils that are identified as meeting GM
Standard
4718M and have the “Starburst” symbol on the
front of the oil container.
Your Corvette engine is filled at the factory with a
Mobil
1 @ synthetic oil, which meets all requirements for
your vehicle.
Substitute Oil (LTl Only): When adding oil to
maintain engine oil level, oil meeting GM Standard
GM47
18M may not be available. You can add substitute
oil designated
SAE 5W-30 with the “Starburst” symbol
or API Service SH at all temperatures. If temperatures
are above
0” F (- 18 O C), you may substitute SAE
1OW-30 with the “Starburst” symbol or API Service
SH
oil. This oil should not be used for an oil change.
Substitute Oil (LT5 Only): When adding oil to
maintain engine oil level,
if an oil meeting GM Standard
GM47
18M is not available, you can use oil designated
SAE 1OW-30 with the “Starburst” symbol or API
~ Service SH at all temperatures. This oil should not be
used for
an oil change.
Engine Oil Additives
Don’t add anything to your oil. Your Chevrolet dealer is
ready to advise if you think something should be added.
When to Change Engine Oil
See if any one of these is true for you:
0 Most trips are less than 5 to 10 miles (8 to 16 km).
This is particularly important when outside
temperatures are below freezing.
Most trips include extensive idling (such as frequent
driving in stop and
go traffic).
Most trips are through dusty areas.
If any one of these is true for your vehicle, you need to
change your oil and filter every 3,000 miles
(5 000 km)
or 3 months -- whichever comes first. (See “Engine Oil
Life Monitor” in the Index.)
If none of them is true, change the oil and filter every
7,500 miles (12 500 km) or 12 months -- whichever
comes first. (See “Engine Oil Life Monitor” in the
Index.)
Engine Coolant Heater
An engine coolant heater can be a big help if you have
to
park outside in very cold weather, 0” F (- 1 8 O C) or
colder. If your vehicle has this feature, see “Engine
Coolant Heater” in the Index.
