tow CHEVROLET CORVETTE 2009 6.G Owner's Guide

The engine oil dipstick handle is a yellow loop.
The dipstick is located on the dry sump engine oil tank.
SeeEngine Compartment Overview on page 5-14
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 when
checking the engine oil level.
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
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 oil level reading,
warm up the engine to at least 175°F (80°C).
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 ve minutes (but not more than
20 minutes) to allow oil to drain and settle in
the engine.
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.

Checking Coolant
The vehicle must be on a level surface when checking
the coolant level.
Check to see if coolant is visible in the coolant surge
tank. If the coolant inside the coolant surge tank is boiling,
do not do anything else until it cools down. If coolant
is visible but the coolant level is not at or above the
FULL COLD mark, add a 50/50 mixture of clean,
drinkable water and DEX-COOL coolant at the coolant
recovery tank, but be sure the cooling system is cool
before this is done. SeeEngine Coolant on page 5-34
for more information.
The engine coolant
surge tank is located
toward the rear of the
engine compartment on
the driver side of the
vehicle. SeeEngine
Compartment Overview
on page 5-14for more
information on location.When the engine is cold, the coolant level should be at
the FULL COLD mark on the coolant surge tank.
When the engine is hot, the level could be higher
than the FULL COLD line. If the coolant is below the
FULL COLD line when the engine is hot, there could
be a leak in the cooling system.
If the coolant is low, add the coolant or take the vehicle
to a dealer/retailer for service.
How to Add Coolant to the Coolant
Surge Tank
{CAUTION:
You can be burned if you spill coolant on hot
engine parts. Coolant contains ethylene glycol
and it will burn if the engine parts are hot enough.
Do not spill coolant on a hot engine.

{CAUTION:
Putting a used wheel on the vehicle is dangerous.
You cannot know how it has been used or how
far it has been driven. It could fail suddenly and
cause a crash. If you have to replace a wheel,
use a new GM original equipment wheel.
Notice:The wrong wheel can also cause problems
with bearing life, brake cooling, speedometer or
odometer calibration, headlamp aim, bumper height,
vehicle ground clearance, and tire clearance to
the body and chassis.
{CAUTION:
Rust or dirt on a wheel, or on the parts to
which it is fastened, can make wheel nuts
become loose after a time. The wheel could
come off and cause a crash. When you
change a wheel, remove any rust or dirt from
places where the wheel attaches to the
vehicle. In an emergency, you can use a cloth
or a paper towel to do this; but be sure to use a
scraper or wire brush later, if you need to, to
get all the rust or dirt off.

3. Lift the vehicle with the jack, making sure the jack
spans at least two of the crossmember ribs (B).

Work on page 5-5.
If a Tire Goes Flat
It is unusual for a tire to blow out while you are driving,
especially if you maintain the tires properly. If air goes
out of a tire, it is much more likely to leak out slowly.
SeeTires on page 5-62for additional information. 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 at tire creates a drag that pulls
the vehicle toward that side. Take your foot off the
accelerator pedal and grip the steering wheel rmly.
Steer to maintain lane position, and 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 would 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.
The vehicle has no spare tire, no tire changing
equipment, and no place to store a tire.

Fabric/Carpet
Use a vacuum cleaner with a soft brush attachment
frequently to remove dust and loose dirt. A canister
vacuum with a beater bar in the nozzle may only be
used on oor carpet and carpeted oor mats. For any
soil, always try to remove it rst with plain water or club
soda. Before cleaning, gently remove as much of the soil
as possible using one of the following techniques:
For liquids: gently blot the remaining soil with a paper
towel. Allow the soil to absorb into the paper towel
until no more can be removed.
For solid dry soils: remove as much as possible and
then vacuum.
To clean:
1. Saturate a lint-free, clean white cloth with water or
club soda.
2. Wring the cloth to remove excess moisture.
3. Start on the outside edge of the soil and gently rub
toward the center. Continue cleaning, using a clean
area of the cloth each time it becomes soiled.4. Continue to gently rub the soiled area until the
cleaning cloth remains clean.
5. If the soil is not completely removed, use a mild
soap solution and repeat the cleaning process
that was used with plain water.
If any of the soil remains, a commercial fabric cleaner
or spot lifter may be necessary. When a commercial
upholstery cleaner or spot lifter is to be used, test a small
hidden area for colorfastness rst. If the locally cleaned
area gives any impression that a ring formation may
result, clean the entire surface.
After the cleaning process has been completed, a paper
towel can be used to blot excess moisture from the
fabric or carpet.
Coated Moldings
These moldings are around the hatch opening in the
rear area.
When lightly soiled, wipe with a sponge or soft
lint-free cloth dampened with water.
When heavily soiled, use warm soapy water.

Dry the nish with a soft, clean chamois or an all-cotton
towel to avoid surface scratches and water spotting.
Notice:If you drive the vehicle through an
automatic car wash that does not have enough
clearance for the wide rear tires and wheels, you
could damage the vehicle. Verify with the manager
of the car wash that the vehicle will t before
entering the car wash or use a touchless car wash.
High pressure car washes may cause water to enter the
vehicle. Avoid using high pressure washes closer than
12 inches (30 cm) to the surface of the vehicle. Use of
power washers exceeding 1,200 psi (8 274 kPa) can
result in damage or removal of paint and decals.
Cleaning Exterior Lamps/Lenses
Use only lukewarm or cold water, a soft cloth and a
car washing soap to clean exterior lamps and lenses.
Follow instructions underWashing Your Vehicle on
page 5-95.
Finish Care
Occasional waxing or mild polishing of the vehicle by
hand may be necessary to remove residue from the paint
nish. Approved cleaning products can be obtained from
your dealer/retailer.
If the vehicle has a basecoat/clearcoat paint nish,
the clearcoat gives more depth and gloss to the colored
basecoat. Always use waxes and polishes that are
non-abrasive and made for a basecoat/clearcoat
paint nish.
Notice:Machine compounding or aggressive
polishing on a basecoat/clearcoat paint nish
may damage it. Use only non-abrasive waxes and
polishes that are made for a basecoat/clearcoat
paint nish on the vehicle.
Foreign materials such as calcium chloride and other
salts, ice melting agents, road oil and tar, tree sap, bird
droppings, chemicals from industrial chimneys, etc., can
damage the vehicle’s nish if they remain on painted
surfaces. Wash the vehicle as soon as possible. If
necessary, use non-abrasive cleaners that are marked
safe for painted surfaces to remove foreign matter.
Exterior painted surfaces are subject to aging, weather
and chemical fallout that can take their toll over a period
of years. To help keep the paint nish looking new, keep
the vehicle garaged or covered whenever possible.

Protecting Exterior Bright Metal Parts
Bright metal parts should be cleaned regularly to keep
their luster. Washing with water is all that is usually
needed. However, chrome polish may be used on
chrome or stainless steel trim, if necessary.
Use special care with aluminum trim. To avoid
damaging protective trim, never use auto or chrome
polish, steam or caustic soap to clean aluminum.
A coating of wax, rubbed to high polish, is recommended
for all bright metal parts.
ZR1 Carbon Fiber Panels
Carbon ber panels can be washed and waxed like any
other panels.
Use a clear or black pigmented wax on the inner hood
carbon ber panel.
ZR1 Hood Window
The hood window on the ZR1 can be cleaned in the
same manner as the headlamp lenses. SeeCleaning
Exterior Lamps/Lenses on page 5-96for more
information.
Windshield and Wiper Blades
Clean the outside of the windshield with glass cleaner.
Clean the rubber blades using a lint free cloth or paper
towel soaked with windshield washer uid or a mild
detergent. Wash the windshield thoroughly when
cleaning the blades. Bugs, road grime, sap, and a
buildup of vehicle wash/wax treatments may cause
wiper streaking. Replace the wiper blades if they are
worn or damaged.
Wipers can be damaged by:
Extreme dusty conditions
Sand and salt
Heat and sun
Snow and ice, without proper removal
5-97

Aluminum or Chrome-Plated Wheels
and Trim
The vehicle may have either aluminum or chrome-plated
wheels.
Keep the wheels clean using a soft clean cloth with mild
soap and water. Rinse with clean water. After rinsing
thoroughly, dry with a soft clean towel. A wax may
then be applied.
Notice:Chrome wheels and other chrome trim may
be damaged if the vehicle is not washed after driving
on roads that have been sprayed with magnesium,
calcium or sodium chloride. These chlorides are
used on roads for conditions such as ice and dust.
Always wash the vehicle’s chrome with soap and
water after exposure.
Notice:Using strong soaps, chemicals, abrasive
polishes, cleaners, brushes, or cleaners that contain
acid on aluminum or chrome-plated wheels, could
damage the surface of the wheel(s). The repairs
would not be covered by the warranty. Use only
approved cleaners on aluminum or chrome-plated
wheels.
The surface of these wheels is similar to the painted
surface of the vehicle. Do not use strong soaps,
chemicals, abrasive polishes, abrasive cleaners,cleaners with acid, or abrasive cleaning brushes
on them because they could damage the surface.
Do not use chrome polish on aluminum wheels.
Notice:Using chrome polish on aluminum wheels
could damage the wheels. The repairs would not
be covered by the warranty. Use chrome polish on
chrome wheels only.
Use chrome polish only on chrome-plated wheels, but
avoid any painted surface of the wheel, and buff off
immediately after application.
Notice:Driving the vehicle through an automatic
car wash that has silicone carbide tire cleaning
brushes, could damage the aluminum or
chrome-plated wheels. The repairs would not be
covered by the warranty. Never drive a vehicle
equipped with aluminum or chrome-plated wheels
through an automatic car wash that uses silicone
carbide tire cleaning brushes.
Tires
To clean the tires, use a stiff brush with tire cleaner.
Notice:Using petroleum-based tire dressing
products on the vehicle may damage the paint nish
and/or tires. When applying a tire dressing, always
wipe off any overspray from all painted surfaces
on the vehicle.
