Brake Pedal Travel
See your dealer/retailer if the brake pedal does
not return to normal height, or if there is a
rapid increase in pedal travel. This could be a sign
that brake service might be required.
Brake Adjustment
Every time you make a brake stop, the brakes
adjust for wear.
Replacing Brake System Parts
The braking system on a vehicle is complex. Its
many parts have to be of top quality and work well
together if the vehicle is to have really good
braking. Your vehicle was designed and tested
with top-quality brake parts. When you replace
parts of the braking system — for example, when
the brake linings wear down and you need
new ones put in — be sure you get new approved
replacement parts. If you do not, the brakesmight not work properly. For example, if someone
puts in brake linings that are wrong for your
vehicle, the balance between the front and rear
brakes can change — for the worse. The braking
performance you have come to expect can
change in many other ways if someone puts in the
wrong replacement brake parts.
Battery
Your vehicle has a maintenance free battery.
When it is time for a new battery, get one that has
the replacement number shown on the original
battery’s label. We recommend an ACDelco
®
replacement battery. SeeEngine Compartment
Overview on page 498for battery location.
Warning:Battery posts, terminals, and related
accessories contain lead and lead compounds,
chemicals known to the State of California
to cause cancer and reproductive harm. Wash
hands after handling.
531

Vehicle Storage
If you are not going to drive your vehicle for
25 days or more, remove the black, negative (−)
cable from the battery. This will help keep the
battery from running down.
{CAUTION:
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 532for tips on working
around a battery without getting hurt.
Jump Starting
If your 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.
{CAUTION:
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 your vehicle that would
not be covered by your warranty.
Trying to start your vehicle by pushing or
pulling it will not work, and it could damage
your vehicle.
1. Check the other vehicle. It must have a
12-volt battery with a negative ground system.
532

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. If you have a vehicle with a diesel engine with
two batteries, you should know before you
begin that, especially in cold weather, you may
not be able to get enough power from a
single battery in another vehicle to start your
diesel engine. If your vehicle has more
than one battery, use the battery that is closer
to the starter — this will reduce electrical
resistance. This is located on the passenger
side, in the rear of the engine compartment.
3. 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 an unwanted ground connection.
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 rmly on both vehicles
involved in the jump start procedure. Put
the automatic transmission in PARK (P) 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 in a drive gear, not in NEUTRAL.
Notice:If you leave your radio or other
accessories on during the jump starting
procedure, they could be damaged. The repairs
would not be covered by your warranty.
Always turn off your radio and other
accessories when jump starting your vehicle.
4. 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 will avoid
sparks and help save both batteries. And it
could save the radio!
533

5. Open the hood on the other vehicle and
locate the positive (+) and negative (−)
terminal locations on that vehicle.
The positive (+) terminal, is located under a
red plastic cover at the positive battery
post. To uncover the positive (+) terminal,
open the red plastic cover.
The remote negative (−) terminal is a stud located
on the right front passenger side of the engine,
where the negative battery cable attaches.
SeeEngine Compartment Overview on page 498
{CAUTION:
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.
{CAUTION:
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 ashlight 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.
CAUTION: (Continued)
534

CAUTION: (Continued)
But if a battery has ller caps, be sure the
right amount of uid is there. If it is low,
add water to take care of that rst. If you
do not, explosive gas could be present.
Battery uid contains acid that can burn
you. Do not get it on you. If you
accidentally get it in your eyes or on your
skin, ush the place with water and get
medical help immediately.
{CAUTION:
Fans or other moving engine parts can
injure you badly. Keep your hands away
from moving parts once the engine is
running.6. Check that the jumper cables do 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.
535

7. Connect the red
positive (+) cable to
the positive (+)
terminal of
the vehicle with the
dead battery.
8. 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.9. 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.
10. Connect the other end of the negative (−)
cable to a heavy, unpainted metal engine
part or to the remote negative (−) terminal, on
the vehicle with the dead battery.
11. Start the vehicle with the good battery and run
the engine for a while.
12. Try to start the vehicle that had the dead
battery. If it will not start after a few tries, it
probably needs service.
