Checking Engine Oil (Z06,
Grand Sport, and Stingray
with Z51)
1. Engine Oil Dipstick
2. Engine Oil Fill Cap
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. The dipstick is located on the
dry sump engine oil tank. See
Engine Compartment Overview
0225 for the location of the dry
sump engine oil tank. These vehicles 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 checking
the engine oil level. Follow this
procedure closely.
The engine oil level must be
checked when the engine is warm.
Cold oil level in the dry sump tank
may not indicate the actual amount
of oil in the system. With this
system, engine oil is contained in an
external tank, separate from the
engine. Under normal operating
conditions, the oil pan under the
engine does not store any oil. If the
vehicle has been parked for an
extended period without the engine
being started, some oil will seep
back into the oil pan, reducing the
amount of oil held in the dry sump
tank and there could be no engine
oil at all showing on the dipstick.
This is normal since the dipstick is
designed to read the engine oil level
only after the engine has run long
enough to reach normal operatingtemperature. 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 oil level 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. Check the oil level between five and 10 minutes after the
engine is shut down.
{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
wipe it with a clean lint-free

{Warning
Heater and radiator hoses, and
other engine parts, can be very
hot. Do not touch them. If you do,
you can be burned.
Do not run the engine if there is a
leak. If you run the engine, it
could lose all coolant. That could
cause an engine fire, and you
could be burned. Get any leak
fixed before you drive the vehicle.
Caution
Using coolant other than
DEX-COOL®can cause
premature engine, heater core,
or radiator corrosion. In addition,
the engine coolant could require
changing sooner. Any repairs
would not be covered by the
vehicle warranty. Always use
DEX-COOL (silicate-free) coolant
in the vehicle.
Cooling System (Aero
Panel)
The aero panel enhances
aerodynamic efficiency and
improves fuel economy.
Remove the aero panel and bracket
to improve engine cooling and air
conditioning performance when
driving aggressively or in hot
weather. To remove the aero panel and
bracket:
Stingray Shown, Grand Sport and
Z06 Similar
1. Press up on the two indents at the bottom and lift the aero
panel off the bracket.

Caution
Neither tire underinflation nor
overinflation is good.
Underinflated tires, or tires
that do not have enough air,
can result in:
.Tire overloading and
overheating which could
lead to a blowout.
.Premature or
irregular wear.
.Poor handling.
.Reduced fuel economy.
Overinflated tires, or tires that
have too much air, can
result in:
.Unusual wear.
.Poor handling.
.Rough ride.
.Needless damage from
road hazards. The Tire and Loading
Information label on the vehicle
indicates the original equipment
tires and the correct cold tire
inflation pressures. The
recommended pressure is the
minimum air pressure needed to
support the vehicle's maximum
load carrying capacity.
On rare occasions, vehicles with
P245/40ZR18 and P285/35ZR19
size tires may experience a
rough ride at the tire pressure
recommended on the Tire and
Loading Information label. To
improve ride performance,
decrease the tire pressure to no
less than 205 kPa (30 psi) when
the tire is cold. This may reduce
fuel economy and cause the low
tire pressure warning to occur
more often.
Inflate the tires to the
recommended pressure once
rough ride road conditions have
passed. For additional information
regarding how much weight the
vehicle can carry, and an
example of the Tire and Loading
Information label, see
Vehicle
Load Limits 0177. How the
vehicle is loaded affects vehicle
handling and ride comfort. Never
load the vehicle with more
weight than it was designed to
carry.
When to Check
Check the tires once a month
or more.
How to Check
Use a good quality pocket-type
gauge to check the tire
pressure. Proper tire inflation
cannot be determined by looking
at the tire. Check the tire
inflation pressure when the tires
are cold, meaning the vehicle
has not been driven for at least
three hours or no more than
1.6 km (1 mi).

Tire Pressure Monitor
System
The Tire Pressure Monitor System
(TPMS) uses radio and sensor
technology to check tire pressure
levels. The TPMS sensors monitor
the air pressure in your tires and
transmit tire pressure readings to a
receiver located in the vehicle.
Each tire, including the spare (if
provided), should be checked
monthly when cold and inflated to
the inflation pressure recommended
by the vehicle manufacturer on the
vehicle placard or tire inflation
pressure label. (If your vehicle has
tires of a different size than the size
indicated on the vehicle placard or
tire inflation pressure label, you
should determine the proper tire
inflation pressure for those tires.)
As an added safety feature, your
vehicle has been equipped with a
tire pressure monitoring system
(TPMS) that illuminates a low tire
pressure telltale when one or more
of your tires is significantly
under-inflated.Accordingly, when the low tire
pressure telltale illuminates, you
should stop and check your tires as
soon as possible, and inflate them
to the proper pressure. Driving on a
significantly under-inflated tire
causes the tire to overheat and can
lead to tire failure. Under-inflation
also reduces fuel efficiency and tire
tread life, and may affect the
vehicle's handling and stopping
ability.
Please note that the TPMS is not a
substitute for proper tire
maintenance, and it is the driver's
responsibility to maintain correct tire
pressure, even if under-inflation has
not reached the level to trigger
illumination of the TPMS low tire
pressure telltale.
Your vehicle has also been
equipped with a TPMS malfunction
indicator to indicate when the
system is not operating properly.
The TPMS malfunction indicator is
combined with the low tire pressure
telltale. When the system detects a
malfunction, the telltale will flash for
approximately one minute and then
remain continuously illuminated.This sequence will continue upon
subsequent vehicle start-ups as
long as the malfunction exists.
When the malfunction indicator is
illuminated, the system may not be
able to detect or signal low tire
pressure as intended. TPMS
malfunctions may occur for a variety
of reasons, including the installation
of replacement or alternate tires or
wheels on the vehicle that prevent
the TPMS from functioning properly.
Always check the TPMS malfunction
telltale after replacing one or more
tires or wheels on your vehicle to
ensure that the replacement or
alternate tires and wheels allow the
TPMS to continue to function
properly.

Convertible Top Care
Frequently hand wash convertible
tops with mild car wash soap. Never
use a stiff brush, steam, bleach,
or aggressive cleaners. If necessary, a soft brush can be
used to remove dirt. When finished
cleaning, thoroughly rinse the fabric.
Avoid automatic car washes with
overhead brushes or very
high-pressure sprays as they can
cause damage and leaking.
Only lower the top when it is
completely dry and avoid leaving
the top lowered for extended
periods of time to prevent excessive
interior weathering.
Avoid leaving large amounts of
snow on the top for extended
periods of time as damage may also
occur.
Carbon Fiber Care
Carbon fiber composite parts can be
washed and waxed like any other
parts. Use a clear or black
pigmented wax. See
Composite
Materials 0182.
Cleaning Exterior Lamps/
Lenses, Emblems, Decals, and
Stripes
Use only lukewarm or cold water, a
soft cloth, and a car washing soap
to clean exterior lamps, lenses,
emblems, decals, and stripes.
Follow instructions under "Washing
the Vehicle" previously in this
section.
Lamp covers are made of plastic,
and some have a UV protective
coating. Do not clean or wipe them
while they are dry.
Do not use any of the following on
lamp covers:
.
Abrasive or caustic agents.
. Washer fluids and other cleaning
agents in higher concentrations
than suggested by the
