Downloaded from www.Manualslib.com manuals search engine As you brake, your computer keeps receiving updates on wheel speed and
controls braking pressure accordingly.
Remember: Anti-lock doesn’t change the time you need to get your foot
up to the brake pedal. If you get too close to the vehicle in front
of you,
you won’t have time to apply your brakes
if that vehicle suddenly slows or
stops. Always leave enough room up ahead to stop, even though you have
anti-lock brakes.
To Use Anti-Lock
Don’t pump the brakes. Just hold the brake pedal down and let anti-lock
work for you. You may hear the anti-lock pump or motor operate, and
feel the brake pedal pulsate, but this is normal.
Traction Control System (Option)
Your vehicle may have a traction control system that limits wheel spin.
This is especially useful
in slippery road conditions. The system operates
only
if it senses that one or both of the front wheels are spinning or
beginning to lose traction. When this happens, the system works the front
brakes and reduces engine power (by shutting
off fuel injectors) to limit
wheel spin.
The “TRACTION ACTIVE” message will display on the Driver
Information Center when
the traction control system is limiting wheel
spin. See “Driver Information Center Messages” in the Index.
You may
feel the system working, or you may notice some noise, but this is normal.
If your vehicle is in cruise control when the traction control system begins
to limit wheel spin, the cruise control will automatically disengage. When
road conditions allow you
to safely use it again, you may re-engage the
cruise control. (See “Cruise Control”
in the Index.)
The “TRACTION DISABLED” message will display on the Driver
Information Center if there’s a problem with your traction control system.
See “Driver Information Center Messages” in the Index. When this
message is displayed, the system will not limit wheel spin. Adjust your
driving accordingly.

Here are some things that will lower fuel economy:
Quick acceleration.
0 Traveling at higher speeds. Traveling at 65 mph instead of 55 mph
Carrying unnecessary weight in the vehicle.
Rewing the engine. This is not ne.cessary for your vehicle.

the wheels and tires out of balance.
Use of electrical accessories which require high amperage when they
Even things beyond your control such as weather conditions affect your
fuel economy. Driving up steep hills,
in rain or snow, and into a strong
wind will lower fuel economy. In the lower left corner of the fuel

NOTICE:
Don’t let anyone tell you that underinflation or overinflation is
all right. It’s not.
If your tires don’t have enough air
(underinflation) you can get:
Too much flexing
Too much heat
Tire overloading
Bad wear
Bad handling
Bad fuel economy.
If your tires have too much air (overinflation), you can get:
Unusual wear
Bad handling
Rough ride
Needless damage from road hazards.
When to Check Check your tires once a month or more.
The tire pressures are:
Front - 30 psi (207 kPa)
Rear - 30 psi (207 kPa)
Recommended tire size
is:
Michelin XW4 Blackwall (P215/70R15)
T125/70RIS (Compact Spare)
c-
How to Check Use a good quality pocket-type gage to check tire
pressure. Simply looking at
the tires will not tell you the pressure,
especially
if you have radial tires -- which may look properly inflated even
if they’re underinflated.
