pan. This will reduce the amount of
oil held in the dry sump tank and
there could be no engine oil 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 operating temperature. Do
not add engine oil based on cold
engine dipstick readings. The
engine oil level on the dipstick must
be checked while the engine is
running at idle.
To check the engine oil:1. Turn the engine on and let it warm up to at least 80 °C (175
°F).
2. Once the engine is warm, check the oil while the engine
is running at idle.
{Warning
The engine oil dipstick handle
may be hot; it could burn you.
Use a towel or glove to touch the
dipstick handle. 3. Remove the dipstick and wipe
it with a clean lint-free paper
towel or a cloth. Re-insert the
dipstick and push it all the way
in until it stops.
4. Remove the dipstick again and read the level on the
cross-hatched area.
5. Turn the engine off.
When to Add Engine Oil
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 fill tube and then recheck
the level. See “Selecting the Right
Engine Oil” later in this section for
the type of oil to use. For engine oil
crankcase capacity, see Capacities
and Specifications 0299.
Caution
Do not add too much oil. Oil
levels above or below the
acceptable operating range
shown on the dipstick are harmful
to the engine. If the oil level is
above the operating range (i.e.,
the engine has so much oil that
the oil level gets above the
cross-hatched area that shows
the proper operating range), the
engine could be damaged. Drain
the excess oil or limit driving of
the vehicle, and seek a service
professional to remove the
excess oil.
See Engine Compartment Overview
0 215 for the location of the external
engine oil tank dipstick and fill cap.
Add enough oil to put the level
somewhere in the proper operating
range. Push the dipstick all the way
back into the oil tank tube when
finished.

Tightening Wheel Lug Nuts
{Warning
Never use oil or grease on studs
or the threads of the wheel nuts.
The wheel nuts might come loose
and the wheel could fall off,
causing a crash.
{Warning
Incorrect wheel nuts or improperly
tightened wheel nuts can cause
the wheel to become loose and
even come off. This could lead to
a crash. Be sure to use the
correct wheel nuts. If you have to
replace them, be sure to get new
GM original equipment
wheel nuts.
Caution
Improperly tightened wheel nuts
can lead to brake pulsation and
rotor damage. To avoid expensive
brake repairs, evenly tighten the
wheel nuts in the proper
sequence and to the proper
torque specification.
Tighten the wheel lug nuts firmly in
a crisscross sequence. See
Capacities and Specifications0299.
Tire Chains
{Warning
Do not use tire chains. There is
not enough clearance. Tire chains
used on a vehicle without the
proper amount of clearance can
cause damage to the brakes,
suspension, or other vehicle
parts. The area damaged by the
tire chains could cause loss of
control and a crash. Use another
type of traction device only if its
manufacturer recommends it for
the vehicle's tire size combination
and road conditions. Follow that
manufacturer's instructions. To
avoid vehicle damage, drive
slowly and readjust or remove the
traction device if it contacts the
vehicle. Do not spin the wheels.
If traction devices are used, install
them on the rear tires.
