SERVICE
ENGINE
SOON
United States Canada
Your
vehicle is equipped with a computer which
monitors operation of the fuel, ignition and emission
control systems.
This system is called OBD 11 (On-Board
Diagnostics-Second Generation) and is intended to
assure that emissions
are at acceptable levels for the
life
of the vehicle, helping to produce a cleaner
environment. The
SERVICE ENGINE SOON light
comes on to indicate that there is 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.
I NOTICE:
If you keep driving your vehicle with this light
on, after a while, your emission controls may not
work as well, your fuel economy may not be as
good and your engine may not run as smoothly.
This could lead to costly repairs that may not be
covered by your warranty.
This light should come on, as a check to show you it is
working, when the ignition is on and the engine is not
running.
If the light doesn’t come on, have it repaired.
This light will also come on during a malfunction in one
of two ways:
Light Flashing -- A misfire condition has been
detected.
A misfire increases vehicle emissions and
may damage the emission control system on your
vehicle. Dealer or qualified service center diagnosis
and service may be required.
Light On Steady -- An emission control system
malfunction has been detected on your vehicle.
Dealer or qualified service center diagnosis and
service may be required.

Downloaded from www.Manualslib.com manuals search engine If the Light Is Flashing
The following may prevent more serious damage to
your vehicle:
0 Reducing vehicle speed.
0 Avoiding hard accelerations.
0 Avoiding steep uphill grades.
If the Light Is On Steady
You may be able to correct the emission system
malfunction by considering the following:
Did you recently put fuel into your vehicle?
If
so, reinstall the fuel cap, making sure to fully install
the cap. The diagnostic system can determine
if the fuel
cap has been left
off or improperly installed. A loose or
missing fuel cap will allow fuel to evaporate into the
atmosphere. A few driving trips with the cap properly
installed should turn the light off.
Did you just drive through a deep puddle of water? If you are towing a trailer, reduce the amount of
cargo being hauled as soon as it is possible.
If the light stops flashing and remains on steady, see “If
the Light
Is On Steady” following.
If the light continues to flash, when it is safe to
do so,
stop the vehicle. Find a safe place to park your vehicle.
Turn the key
off, wait at least 10 seconds and restart the
engine.
If the light remains on steady, see “If the Light
Is On Steady” following. If the light is still flashing,
follow
the previous steps, and drive the vehicle to your
dealer or qualified service center for service. If
so, your electrical system may be wet.
The condition
will usually be corrected when the electrical system
dries out.
A few driving trips should turn the light off.
Are you low on fuel?
As your engine starts to run out
of fuel, your engine may
not run as efficiently as designed since small amounts of
air are sucked into the fuel line causing a misfire. The
system can detect this. Adding fuel should correct this
condition. Make sure to install the fuel cap properly. It
will take a few driving trips to turn the light off.
Have you recently changed brands of fuel?

These features allow both drivers to personalize their
own climate control settings
as well as their radio
settings. For more information, see “Climate Control
Personalization” and “Radio Personalization” in
the Index.
The outside temperature is always available for display
when your vehicle is running unless an overriding
Driver Information Center message appears. You can
change the temperature from Fahrenheit to Celsius by
pressing the ENGMET (EnglisWmetric) button on the
instrument panel. For more information on the Driver
Information Center, see “Driver Information Center
Messages” in the Index.
The electronic sensor can be affected by road or engine
heat during idling, slow driving or when the engine
is
first stared after a short trip. In order to ensure proper
automatic climate control operation, the outside air
temperature display may not update as quickly as
expected.
This is to allow the air surrounding the outside
temperature sensor to be as close to the actual outside
conditions as possible. This is determined by how much
time has elapsed since the vehicle has been turned off and by vehicle speed.
Control Buttons
RESET TRIP AB: By
using this button, you can
tell how far.you’ve gone
since you last set the trip
reset back to zero. To reset,
press and hold the button
until zeros appear.
If your vehicle is domestic, the trip odometer will return
to zero after 999.9 miles
(1 609 km). If your vehicle is
Canadian, the trip odometer will
return to zero after
1 999.9 km (1,242 miles). The TRIP RESET button only
resets the trip odometer
(A or B) that is being displayed.
Each trip odometer has
to be reset individually.
