{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 10‑88 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.

When to Check Lubricant
Refer to Scheduled Maintenance on
page 11‑2 to determine when to
check the lubricant.
How to Check Lubricant
Active Transfer Case
A. Fill Plug
B. Drain Plug To get an accurate reading, the
vehicle should be on a level
surface.
If the level is below the bottom of
the fill plug hole, some lubricant will
need to be added. Add enough
lubricant to raise the level to the
bottom of the fill plug hole. Use care
not to overtighten the plug.
When to Change Lubricant
Refer to
Scheduled Maintenance on
page 11‑2 to determine how often to
change the lubricant.
What to Use
Refer to Recommended Fluids
and Lubricants on page 11‑7 to
determine what kind of lubricant
to use.

Jump Starting
For more information about the
vehicle battery, seeBattery on
page 10‑28.
If the vehicle is a Hybrid, see the
Hybrid manual for more information.
If the vehicle's battery (or batteries)
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: Only use a vehicle that
has a 12-volt system with a
negative ground for jump
starting. If the other vehicle does
not have a 12-volt system with a
negative ground, both vehicles
can be damaged.

2. Get the vehicles close enoughso 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. 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 the automatic
transmission in P (Park) or a
manual transmission in
N (Neutral) before setting the
parking brake. If the vehicle has
a four-wheel-drive transfer case
with a N (Neutral) position, be
sure the transfer case is in a
drive gear, not in N (Neutral). Notice:
If the radio or other
accessories are left 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 the lamps that are not
needed. This avoids sparks and
helps save both batteries. And it
could save the radio! 4. Open the hood on the
other vehicle and locate the
positive (+) and negative (−)
terminal locations on that
vehicle.
Your vehicle has a remote
positive (+) jump starting
terminal and a remote
negative (−) jump starting
terminal. You should always use
these remote terminals instead
of the terminals on the battery.
If the vehicle has a remote
positive (+) terminal, it is located
under a red plastic cover at the
positive battery post. To uncover
the remote positive (+) terminal,
open the red plastic cover.

10-90 Vehicle Care
The remote negative (−) terminal
is a stud located on the right
front of the engine, where the
negative battery cable attaches.
SeeEngine Compartment
Overview on page 10‑6 for more
information on the location of the
remote positive (+) and remote
negative (−) terminals.
{WARNING
An electric fan can start up even
when the engine is not running
and can injure you. Keep hands,
clothing and tools away from any
underhood electric fan.
{WARNING
Using an open flame 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 battery has enough
water. You do not need to add
water to the battery 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,
(Continued)
WARNING (Continued)
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.
{WARNING
Fans or other moving engine
parts can injure you badly. Keep
your hands away from moving
parts once the engine is running.

5. Check that the jumper cablesdo not have loose or missing
insulation. If they do, you could
get a shock. The vehicles could
be damaged too.
Before you connect the cables,
here are some basic things you
should know. Positive (+) will go
to positive (+) or to a remote
positive (+) terminal if the vehicle
has one. Negative (−) will go to a
heavy, unpainted metal engine
part or to a remote negative (−)
terminal if the vehicle has one.
Do not connect positive (+) to
negative (−) or you will get a
short that would damage the
battery and maybe other parts
too. And do not connect the
negative (−) cable to the
negative (−) terminal on the
dead battery because this can
cause sparks.
6. Connect the red positive (+)
cable to the positive (+) terminal
of the vehicle with the dead
battery. Use a remote
positive (+) terminal if the
vehicle has one.
7. Do not let the other end touch metal. Connect it to the
positive (+) terminal of the
good battery. Use a remote
positive (+) terminal if the
vehicle has one. 8. Now connect the black
negative (−) cable to the
negative (−) terminal of the
good battery. Use a remote
negative (−) terminal if the
vehicle has one.
Do not let the other end touch
anything until the next step. The
other end of the negative (−)
cable does not go to the dead
battery. It goes to a heavy,
unpainted metal engine part
or to the remote negative (−)
terminal on the vehicle with the
dead battery.
9. Connect the other end of the negative (−) cable to the remote
negative (−) terminal, on the
vehicle with the dead battery.
10. Now start the vehicle with the good battery and run the
engine for a while.
