The shift lock release is always
functional except in the case of a
an uncharged or low voltage (less
than 9 volt) battery.
If the vehicle has an uncharged
battery or a battery with low voltage,
try charging or jump starting the
battery. SeeJump Starting
on
page 10‑86for more information.
To shift out of P (Park):
1. Apply the brake pedal.
2. Then press the shift lever button.
3. Move the shift lever to the desired position. If you still are unable to shift out
of P (Park):
1. Fully release the shift lever
button.
2. While holding down the brake pedal, press the shift lever
button again.
3. Move the shift lever to the desired position.
If you still cannot move the shift
lever from P (Park), consult your
dealer or a professional towing
service.
Parking
If the vehicle has a manual
transmission, before you get out of
the vehicle, move the shift lever into
R (Reverse), and firmly apply the
parking brake. Once the shift lever
has been placed into R (Reverse)
with the clutch pedal pressed in,
turn the ignition key to LOCK/OFF,
remove the key and release the
clutch.
If you are parking on a hill, or if
the vehicle is pulling a trailer, see

Vehicle Storage
{WARNING
Batteries have acid that can burn
you and gas that can explode.
You can be badly hurt if you are
not careful. SeeJump Starting
on
page 10‑86
for tips on working
around a battery without
getting hurt.
Infrequent Usage: Remove the
black, negative (−) cable from the
battery to keep the battery from
running down.
Extended Storage: Remove the
black, negative (−) cable from the
battery or use a battery trickle
charger.
Four-Wheel Drive
It is recommended that the
four-wheel drive transfer case fluid
be checked and filled by the dealer.
Front Axle
It is not necessary to regularly
check front axle fluid unless a leak
is suspected or an unusual noise is
heard. A fluid loss could indicate a
problem.
It is recommended that the front
axle fluid be checked and filled by
your dealer.
Rear Axle
When to Check and Change
Lubricant
It is not necessary to regularly
check rear axle fluid unless a leak is
suspected or an unusual noise is
heard. A fluid loss could indicate a
problem. Have it inspected and
repaired.
How to Check Lubricant
To get an accurate reading, the
vehicle should be on a level
surface.
A. Rear Axle
B. Filler Plug
The proper level for the rear
axle fluid is 0 mm to 10 mm
(0 to 3/8 inch) below the bottom of
the filler plug hole, located on the
rear axle.
What to Use
See Recommended Fluids and
Lubricantson page 11‑8to
determine which kind of lubricant
to use.

10-86 Vehicle Care
After installing the spare tire on your
vehicle, you should stop as soon as
possible and make sure the spare is
correctly inflated.
The spare tire does not have a Tire
Pressure Monitor System sensor.
You may get a low pressure warning
light. SeeTire Pressure Monitor
Operation
on page 10‑53. Have the
damaged or flat road tire repaired or
replaced as soon as you can.
Do not mix tires and wheels of
different sizes, because they will
not fit. Keep your spare tire and its
wheel together.
Jump Starting
If the vehicle's battery has run
down, you may want to use another
vehicle and some jumper cables to
start your vehicle. Be sure to use
the following steps to do it safely.
{WARNING
Batteries can hurt you. They can
be dangerous because:
.They contain acid that can
burn you.
.They contain gas that can
explode or ignite.
.They contain enough
electricity to burn you.
If you do not follow these steps
exactly, some or all of these
things can hurt you. Notice:
Ignoring these steps
could result in costly damage to
the vehicle that would not be
covered by the warranty.
Trying to start the vehicle by
pushing or pulling it will not
work, and it could damage the
vehicle.
1. Check the other vehicle. It must
have a 12‐volt battery with a
negative ground system.
Notice: If the other vehicle's
system is not a 12-volt system
with a negative ground, both
vehicles can be damaged. Only
use vehicles with 12-volt systems
with negative grounds to jump
start your vehicle.
2. Get the vehicles close enough so the jumper cables can reach,
but be sure the vehicles are not
touching each other. If they
are, it could cause a ground
connection you do not want.

Vehicle Care 10-87
You would not be able to start
your vehicle, and the bad
grounding could damage the
electrical systems.
To avoid the possibility of the
vehicles rolling, set the parking
brake firmly on both vehicles
involved in the jump start
procedure. Put an automatic
transmission in P (Park) or a
manual transmission in Neutral
before setting the parking brake.
If you have a four-wheel-drive
vehicle, be sure the transfer
case is not in Neutral.
Notice: If you leave the radio or
other accessories on during the
jump starting procedure, they
could be damaged. The repairs
would not be covered by the
warranty. Always turn off the
radio and other accessories
when jump starting the vehicle. 3. Turn off the ignition on both
vehicles. Unplug unnecessary
accessories plugged into the
cigarette lighter or the accessory
power outlets. Turn off the radio
and all lamps that are not
needed. This will avoid sparks
and help save both batteries.
And it could save the radio!
4. Open the hoods and locate the batteries on both vehicles. You
will use the positive (+) battery
terminal and the remote
negative (−) jump starting
terminal to jump start your
vehicle. To access the
positive (+) battery terminal,
open the terminal cover. See
Engine Compartment Overview
on page 10‑6for more
information on the terminal
locations.
{WARNING
Using a match near a battery can
cause battery gas to explode.
People have been hurt doing this,
and some have been blinded.
Use a flashlight if you need more
light.
Be sure the batteries have
enough water. You do not need
to add water to the ACDelco
®
battery (or batteries) installed in
your new vehicle. But if a battery
has filler caps, be sure the right
amount of fluid is there. If it is low,
add water to take care of that
first. If you do not, explosive gas
could be present.
Battery fluid contains acid that
can burn you. Do not get it on
you. If you accidentally get it in
your eyes or on your skin, flush
the place with water and get
medical help immediately.

Vehicle Care 10-89
10. Now start the vehicle with thegood battery and run the
engine for a while.
11. Try to start the vehicle that had the dead battery. If it will
not start after a few tries, it
probably needs service.
Notice: If the jumper cables are
connected or removed in the
wrong order, electrical shorting
may occur and damage the
vehicle. The repairs would not be
covered by the vehicle warranty.
Always connect and remove the
jumper cables in the correct
order, making sure that the
cables do not touch each other
or other metal.
Jumper Cable Removal
A. Heavy, Unpainted Metal Engine Part or Remote Negative (−)
Terminal
B. Good Battery or Remote Positive (+) and Remote
Negative (−) Terminals
C. Dead Battery or Remote Positive (+) Terminal To disconnect the jumper cables
from both vehicles, do the following:
1. Disconnect the black
negative (−) cable from the
vehicle that had the dead
battery.
2. Disconnect the black negative (−) cable from the
vehicle with the good battery.
3. Disconnect the red positive (+) cable from the vehicle with the
good battery.
4. Disconnect the red positive (+) cable from the other vehicle.
5. Return the positive (+) battery terminal cover to its original
position.
