254 Vehicle Care checking a cold engine prior to
starting. Remove the dipstick
and check the level.
.
If unable to wait two hours, the
engine must be off for at least
15 minutes if the engine is
warm, or at least 30 minutes if
the engine is not warm. Pull out
the dipstick, wipe it with a clean
paper towel or cloth, then push it
back in all the way. Remove it
again, keeping the tip down, and
check the level.
When to Add Engine Oil
If the oil is below the cross-hatched
area at the tip of the dipstick and
the engine has been off for at least
15 minutes, add 1 L (1 qt) of the
recommended oil and then recheck
the level. See “ Selecting the Right
Engine Oil ” later in this section for an explanation of what kind of oil to
use. For engine oil crankcase
capacity, see Capacities and
Specifications 0 341 .
CautionDo 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
0 252 for the location of the engine
oil fill cap. Add enough oil to put the level
somewhere in the proper operating
range. Push the dipstick all the way
back in when through.
Selecting the Right Engine Oil Selecting the right engine oil
depends on both the proper oil
specification and viscosity grade.
See Recommended Fluids and
Lubricants 0 337 .
Specification
Ask for and use full synthetic engine
oils that meet the dexos1
specification. Engine oils that have
been approved by GM as meeting
the dexos1 specification are marked
with the dexos1 approved logo. See
www.gmdexos.com.

Vehicle Care 307
{ WarningNever use oil or grease on bolts
or nuts because the nuts might
come loose. The vehicle's wheel
could fall off, causing a crash.
12. Reinstall the wheel nuts.
Tighten each nut by hand until
the wheel is held against
the hub.
13. Lower the vehicle by turning
the jack handle
counterclockwise.
{ WarningWheel nuts that are improperly or
incorrectly tightened can cause
the wheels to become loose or
come off. The wheel nuts should
be tightened with a torque wrench
to the proper torque specification
after replacing. Follow the torque
specification supplied by the
aftermarket manufacturer when
(Continued) Warning (Continued) using accessory locking wheel
nuts. See Capacities and
Specifications 0 341 for original
equipment wheel nut torque
specifications.
CautionImproperly 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. See
Capacities and Specifications
0 341 for the wheel nut torque
specification. 14. Tighten the wheel nuts firmly in
a crisscross sequence, as
shown.
15. Lower the jack all the way and
remove the jack from under the
vehicle.
16. Tighten the wheel nuts firmly
with the wheel wrench.
When reinstalling the wheel cover or
center cap on the full-size tire,
tighten all six plastic caps hand
snug with the aid of the wheel
