If torque lock does occur, you may
need to have another vehicle push
yours a little uphill to take some of
the pressure from the parking pawl
in the transmission. You will then be
able to pull the shift lever out of
P (Park).
Shifting out of Park
This vehicle is equipped with an
electronic shift lock release system.
The system is designed to prevent
movement of the shift lever out of
P (Park), unless the brake pedal is
applied and the ignition is on or in
Service Mode.
The shift lock release is always
functional except in the case of an
uncharged or low voltage–less
than 9 volt –battery.
If the vehicle has an uncharged or
low voltage battery, try charging or
jump starting the battery. See Jump
Starting - North America 0415. To shift out of P (Park):
1. Apply the brake pedal.
2. Release the parking brake if it is applied. See Electric Parking
Brake 0229.
3. Pull the shift lever toward you, then move it to the desired
position, and release.
If the vehicle still cannot be shifted
out of P (Park): 1. Ease the pressure on, or release the shift lever.
2. While holding the brake pedal, push the shift lever all the way
into P (Park).
3. Pull the shift lever toward you, then move it to the desired
position, and release.
If there is still a problem shifting,
have the vehicle serviced soon.
Parking over Things
That Burn
{Warning
Things that can burn could touch
hot exhaust parts under the
vehicle and ignite. Do not park
over papers, leaves, dry grass,
or other things that can burn.
Active Fuel Management
If equipped, Active Fuel
Management allows the gasoline
engine to operate on either all of its
cylinders, or a reduced number of
cylinders, depending on the driving
conditions. When less power is
required, such as cruising at a
constant vehicle speed, the system
will enable reduced cylinder
operation, allowing the vehicle to
achieve better fuel economy. When
greater power is required, such as
accelerating from a stop, passing,
or merging onto a freeway, the
system will maintain full-cylinder
operation.

Engine Oil
For diesel engine vehicles, see
“Engine Oil” in the Duramax diesel
supplement.
To ensure proper engine
performance and long life, careful
attention must be paid to engine oil.
Following these simple, but
important steps will help protect
your investment:
. Use engine oil approved to the
proper specification and of the
proper viscosity grade. See
“Selecting the Right Engine Oil”
in this section. .
Check the engine oil level
regularly and maintain the
proper oil level. See “Checking
Engine Oil” and“When to Add
Engine Oil” in this section.
. Change the engine oil at the
appropriate time. See Engine Oil
Life System 0337.
. Always dispose of engine oil
properly. See “What to Do with
Used Oil” in this section.Checking Engine Oil
Check the engine oil level regularly,
every 650 km (400 mi), especially
prior to a long trip. The engine oil
dipstick handle is a loop. See
Engine Compartment Overview
0328 for the location.
{Warning
The engine oil dipstick handle
may be hot; it could burn you.
Use a towel or glove to touch the
dipstick handle.

The vehicle may have a different
size spare tire than the road tires
originally installed on the vehicle.
This spare tire was developed for
use on this vehicle, so it is all right
to drive on it. If the vehicle has
four-wheel drive and a different size
spare tire is installed, drive only in
two-wheel drive.
After installing the spare tire on the
vehicle, stop as soon as possible
and check that the spare tire is
correctly inflated.
Have the damaged or flat road tire
repaired or replaced and installed
back onto the vehicle as soon as
possible so the spare tire will be
available in case it is needed again.
Do not mix tires and wheels of
different sizes, because they will not
fit. Keep your spare tire and its
wheel together. If the vehicle has a
spare tire that does not match the
original road tires and wheels in size
and type, do not include the spare in
the tire rotation.Jump Starting
