Oil Life
Press the information button until OIL LIFE displays.
This mode shows an estimate of the oil’s remaining
useful life. If you see OIL LIFE 99% on the display, that
means 99% of the current oil life remains. The engine
oil life system will alert you to change the oil on a
schedule consistent with your driving conditions.
When the remaining oil life is low, the CHANGE OIL
SOON message will appear on the display. You should
change the oil as soon as possible. SeeEngine Oil on
page 5-13. In addition to the engine oil life system
monitoring the oil life, additional maintenance is
recommended in the Maintenance Schedule in this
manual. SeeScheduled Maintenance on page 6-4
for more information.
Remember, you must reset the OIL LIFE yourself
after each oil change. It will not reset itself. Also,
be careful not to reset the OIL LIFE accidentally at any
time other than when the oil has just been changed.
It cannot be reset accurately until the next oil change.
To reset the engine oil life system, seeEngine Oil
Life System on page 5-16. The display will show 100%
when the system is reset.
Tire Pressure
Press the information button until FRONT TIRE
PRESSURE displays. This mode shows the pressure
for the front tires. To view the pressure for the rear tires,
press the information button again until REAR TIRE
PRESSURE displays. The tire pressure will be shown in
either pounds per square inch (psi) or kilopascals (kPa).
If a low tire pressure condition is detected by the system
while driving, a message advising you to check the
pressure in a specic tire will appear in the display.
The tire pressure light will also ash and then remain
on during the same ignition cycle. SeeInflation - Tire
Pressure on page 5-54andDIC Warnings and Messages
on page 3-58for more information.
If the tire pressure display shows dashes or blanks
instead of a value, there may be a problem with your
vehicle. If this consistently occurs, see your dealer
for service.

Antilock Brake System (ABS)
Your vehicle has the Antilock Brake System (ABS), an
advanced electronic braking system that will help
prevent a braking skid.
When you start the engine and begin to drive away,
ABS will check itself. You might hear a momentary
motor or clicking noise while this test is going on, and
you might even notice that the brake pedal moves
or pulses a little. This is normal.
If there is a problem with
ABS, this warning light will
stay on. SeeAntilock
Brake System Warning
Light on page 3-42.
Let us say the road is wet and you are driving safely.
Suddenly, an animal jumps out in front of you. You slam
on the brakes and continue braking. Here is what
happens with ABS:
A computer senses that wheels are slowing down. If
one of the wheels is about to stop rolling, the computer
will separately work the brakes at each wheel.ABS can change the brake pressure faster than any
driver could. The computer is programmed to make the
most of available tire and road conditions. This can
help you steer around the obstacle while braking hard.
As you brake, the computer keeps receiving updates
on wheel speed and controls braking pressure
accordingly.
Remember: ABS does not change the time you need to
get your foot up to the brake pedal or always decrease
stopping distance. If you get too close to the vehicle
in front of you, you will not have time to apply the brakes
if that vehicle suddenly slows or stops. Always leave
enough room up ahead to stop, even though you have
ABS.
Using ABS
Do not pump the brakes. Just hold the brake pedal
down rmly and let antilock work for you. You might feel
a slight brake pedal pulsation or notice some noise,
but this is normal.

You can run the engine to keep warm, but be careful.
{CAUTION:
Snow can trap exhaust gases under your
vehicle. This can cause deadly CO (carbon
monoxide) gas to get inside. CO could
overcome you and kill you. You cannot see it
or smell it, so you might not know it is in your
vehicle. Clear away snow from around the
base of your vehicle, especially any that is
blocking the exhaust pipe. And check around
again from time to time to be sure snow does
not collect there.
Open a window just a little on the side of the
vehicle that is away from the wind. This will
help keep CO out.
Run your engine only as long as you must. This saves
fuel. When you run the engine, make it go a little
faster than just idle. That is, push the accelerator
slightly. This uses less fuel for the heat that you get and
it keeps the battery charged. You will need a
well-charged battery to restart the vehicle, and possibly
for signaling later on with the headlamps. Let the
heater run for a while.
4-19

{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. 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.
5. 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. 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 dead battery. Use a remote
positive (+) terminal if the vehicle has one.

Maintenance Footnotes
#Lubricate the suspension, steering linkage, and the
underbody contact points and linkage.
(a)Visually inspect brake lines and hoses for proper
hook-up, binding, leaks, cracks, chafing, etc. Inspect
disc brake pads for wear and rotors for surface
condition. Inspect other brake parts, including calipers,
parking brake, etc. Check parking brake adjustment.
(b)Visually inspect front and rear suspension and
steering system for damaged, loose, or missing parts,
signs of wear, or lack of lubrication. Inspect power
steering lines and hoses for proper hook-up, binding,
leaks, cracks, chafing, etc.
(c)Visually inspect hoses and have them replaced if they
are cracked, swollen, or deteriorated. Inspect all pipes,
fittings and clamps; replace with genuine parts as
needed. To help ensure proper operation, a pressure
test of the cooling system and pressure cap and cleaning
the outside of the radiator and air conditioning condenser
is recommended at least once a year.
(d)Inspect wiper blades for wear, cracking, or
contamination. Clean the windshield and wiper blades,
if contaminated. Replace wiper blades that are wornor damaged. See Windshield Wiper Blade Replacement
on page 5-47 and Windshield, Backglass, and Wiper
Blades on page 5-95 for more information.
(e)Make sure the safety belt reminder light and safety
belt assemblies are working properly. If your vehicle
has a built-in child restraint, make sure the harness
straps, latch plates, buckle, clip, child head restraint, and
anchorages are working properly. Look for any other
loose or damaged safety belt system parts. If you
see anything that might keep a safety belt system from
doing its job, have it repaired. Have any torn or
frayed safety belts replaced. Also see Checking the
Restraint Systems on page 1-91.
(f)Lubricate all key lock cylinders, hood latch
assemblies, secondary latches, pivots, spring anchor
and release pawl, hood and door hinges, rear folding
seats, liftgate hinges, fuel door hinge, power sliding
door cable, and sliding door track(s). More frequent
lubrication may be required when exposed to a corrosive
environment. Applying silicone grease on weatherstrips
with a clean cloth will make them last longer, seal
better, and not stick or squeak.
(g)If you drive regularly under dusty conditions, inspect
the filter at each engine oil change.
