Fuels in Foreign Countries
If you plan on driving in another country outside
the United States or Canada, the proper fuel
might be hard to nd. Never use leaded gasoline
or any other fuel not recommended in the
previous text on fuel. Costly repairs caused by
use of improper fuel would not be covered
by your warranty.
To check the fuel availability, ask an auto club,
or contact a major oil company that does business
in the country where you will be driving.
Filling the Tank
{CAUTION:
Fuel vapor burns violently and a fuel re
can cause bad injuries. To help avoid
injuries to you and others, read and follow
all the instructions on the pump island.
Turn off your engine when you are
refueling. Do not smoke if you are near
fuel or refueling your vehicle. Do not use
cellular phones. Keep sparks, ames,
and smoking materials away from fuel.
Do not leave the fuel pump unattended
when refueling your vehicle. This is
against the law in some places. Do not
re-enter the vehicle while pumping fuel.
Keep children away from the fuel pump;
never let children pump fuel.
324

Checking Things Under
the Hood
{CAUTION:
An electric fan under the hood can start
up and injure you even when the engine
is not running. Keep hands, clothing,
and tools away from any underhood
electric fan.
{CAUTION:
Things that burn can get on hot engine
parts and start a re. These include
liquids like fuel, oil, coolant, brake uid,
windshield washer and other uids, and
plastic or rubber. You or others could be
burned. Be careful not to drop or spill
things that will burn onto a hot engine.

Checking Engine Oil (Except Z06)
If the CHECK OIL LEVEL message on the Driver
Information Center (DIC) comes on, check the
engine oil level right away. For more information,
seeDriver Information Center (DIC) on page 207.
You should check the engine oil level regularly;
this is an added reminder.
It is a good idea to check the engine oil level
every time you get fuel. In order to get an accurate
reading, the oil must be warm and the vehicle
must be on level ground.
The engine oil dipstick handle is a yellow loop.
SeeEngine Compartment Overview on page 330
for the location of the engine oil dipstick.
1. Turn off the engine and give the oil a few
minutes to drain back into the oil pan. If
you do not do this, the oil dipstick might not
show the actual level.
2. Pull out the dipstick and clean it with a
lint-free paper towel or a cloth, then push
it back in all the way. Remove it again,
keeping the tip down.
333

Checking Engine Oil (Z06 Only)
A. Engine Oil Dipstick
B. Engine Oil Fill CapIt is a good idea to check the engine oil level
every time you get fuel. In order to get an accurate
reading, the oil must be warm and the vehicle
must be on level ground.
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 330for the location of the dry sump
engine oil tank.
Z06 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 checking the engine oil level.
Follow this procedure closely when checking the
engine oil level.
334

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.
335

A. Engine Oil Drain Plug
B. Seal
1. Remove the two engine oil drain plugs
from the bottom of the engine oil pan.
One drain plug drains the external oil tank
via the oil transfer supply line. The other
drain plug drains residual oil from the
crankcase sump. Allow the oil to drain.2. Once the oil has been drained from the
engine, remove the engine oil lter and
allow the oil to drain.
3. Re-install both drain plugs and tighten them
to 18 lb ft (25
Y).
4. Replace the oil lter and tighten it to
18 lb ft (25
Y). SeeNormal Maintenance
Replacement Parts on page 445for the
correct lter.
5. Oil is lled through the opening in the top
of the external engine oil tank. Remove the
oil ll cap.
6. Add eight quarts (7.6 L) of oil to the oil tank.
SeeCapacities and Specications on
page 426.
7. Install the oil ll 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 Only).”
338

When the system has calculated that oil life has
been diminished, it will indicate that an oil change
is necessary. A CHANGE ENGINE OIL message
will come on. Change your oil as soon as possible
within the next 600 miles (1 000 km). It is
possible that, if you are driving under the best
conditions, the oil life system may not indicate
that an oil change is necessary for over a
year. However, your engine oil and lter must
be changed at least once a year and at this
time the system must be reset. Your dealer
has GM-trained service people who will perform
this work using genuine GM parts and reset
the system. It is also important to check your
oil regularly and keep it at the proper level.
If the system is ever reset accidentally, you
must change your oil at 3,000 miles (5 000 km)
since your last oil change. Remember to reset
the oil life system whenever the oil is changed.How to Reset the Engine Oil Life
System
The Engine Oil Life System calculates when to
change your engine oil and lter based on vehicle
use. Anytime your oil is changed, reset the
system so it can calculate when the next oil
change is required. If a situation occurs where
you change your oil prior to a CHANGE ENGINE
OIL message being turned on, reset the system.
To reset the CHANGE ENGINE OIL message
after an oil change, do the following:
1. Press the TRIP button so the OIL 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 you start your vehicle, the engine
oil life system has not reset. Repeat the procedure.

What to Use
Use a mixture of one-half clean, drinkable water
and one-half DEX-COOL®coolant which will
not damage aluminum parts. If you use this coolant
mixture, you do not need to add anything else.
{CAUTION:
Adding only plain water to your cooling
system can be dangerous. Plain water,
or some other liquid such as alcohol, can
boil before the proper coolant mixture will.
Your vehicle’s coolant warning system
is set for the proper coolant mixture. With
plain water or the wrong mixture, your
engine could get too hot but you would
not get the overheat warning. Your engine
could catch re and you or others could
be burned. Use a 50/50 mixture of clean,
drinkable water and DEX-COOL
®coolant.Notice:If you use an improper coolant
mixture, your engine could overheat and be
badly damaged. The repair cost would not be
covered by your warranty. Too much water
in the mixture can freeze and crack the engine,
radiator, heater core, and other parts.
If you have to add coolant more than four times
a year, have your dealer check your cooling
system.
Notice:If you use extra inhibitors and/or
additives in your vehicle’s cooling system,
you could damage your vehicle. Use only
the proper mixture of the engine coolant
listed in this manual for the cooling system.

on page 443for more information.
