Analog Cluster
This gage shows the
engine coolant
temperature. If the gage
pointer moves into the red area, the engine is too hot.
That reading means the same thing as the warning
light
-- the engine coolant
has overheated.
In the
section “Problems on the
Road,” this manual
explains what to do. See
“Engine Overheating” in
the Index.

assure that emissions are at acceptable levels for the life
of the vehicle, helping to produce a cleaner
environment. The

a problem and service is required. Malfunctions often
will be indicated by the system before
any problem is
apparent. This may prevent more serious damage
to
your vehicle. This system is also designed to assist your
service technician in correctly diagnosing
any
malfunction.

Downloaded from www.Manualslib.com manuals search engine Remember: Anti-lock doesn’t 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 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.
Using Anti-Lock
Don’t pump the brakes. Just hold the brake pedal down
firmly and let anti-lock work for you. You may hear the
anti-lock pump or motor operate, and
1 1 the brake
pedal pulsate, but this is normal.
Traction Control System
Your vehicle has 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 to limit wheel spin.
The TRACTION
ENGAGED 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 or hear the
system working, 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
reengage the cruise control. (See “Cruise Control” in
the Index.)
TRACTION
CONTROL
This warning light will come on to let you know if
there’s a problem with your
traction control system.
See “Traction Control System Warning Light” in the
Index. When this warning light is on, the system will not
limit wheel spin. Adjust your driving accordingly.
The traction control system automatically comes on whenever you start your vehicle. To limit wheel spin,
especially in slippery road conditions, you should always leave the system
on. But you can turn the
traction control system
off if you ever need to. (You
should turn the system
off if your vehicle ever gets stuck
in sand, mud, ice or snow. See ‘.‘Rocking Your Vehicle”
in the Index.)

Downloaded from www.Manualslib.com manuals search engine City Driving Here are ways to increase your safety in city driving:
Know the best way to get to where you are
going. Get
a city map and plan your trip into an
unknown part of the city just as you would for a
cross-country trip.
Try to use the freeways that rim and crisscross most
large cities. You’ll save time and energy. (See the
next part, “Freeway Driving.”)
One
of the biggest problems with city streets is the
amount
of traffic on them. You’ll want to watch out for
what the other drivers are doing and pay attention to
traffic signals.
Treat a green light as a warning signal. A traffic
light is there because the comer is busy enough to
need it. When
a light turns green, and just before you
start to move, check both ways for vehicles that have
not cleared the intersection or may be running the
red light.

Overheated Engine Protection
Operating Mode
NOTICE:
After driving in the overheated engine protection
operating mode, to avoid engine damage, allow
the engine to cool before attempting any repair.
The engine oil will be severely degraded. Repair
the cause of coolant loss, change the oil and reset
the oil life indicator. See “Engine Oil, When to
Change” in the Index.
Should an overheated engine condition exist and the
message ENGINE OVERHEATED STOP ENGINE is
displayed, an overheat protection mode which alternates
firing groups
of four cylinders helps prevent engine
damage.
In this mode, you will notice a loss in power
and engine performance. This operating mode allows
your vehicle to be driven to a safe place in
an
emergency; you may drive up to 50 miles (80 lun).
Towing a trailer in the overheat protection mode should
be avoided.
