check engine light CHEVROLET EPICA 2004 1.G User Guide

Once you are moving on the freeway, make certain
you allow a reasonable following distance.
Expect to move slightly slower at night.
When you want to leave the freeway, move to the proper
lane well in advance. If you miss your exit, do not, under
any circumstances, stop and back up. Drive on to the
next exit.
The exit ramp can be curved, sometimes quite sharply.
The exit speed is usually posted. Reduce your speed
according to your speedometer, not to your sense
of motion. After driving for any distance at higher
speeds, you may tend to think you are going slower
than you actually are.
Before Leaving on a Long Trip
Make sure you are ready. Try to be well rested. If you
must start when you are not fresh — such as after
a day’s work — do not plan to make too many miles that
first part of the journey. Wear comfortable clothing
and shoes you can easily drive in.Is your vehicle ready for a long trip? If you keep it
serviced and maintained, it is ready to go. If it needs
service, have it done before starting out. Of course, you
will find experienced and able service experts in GM
dealerships all across North America. They will be ready
and willing to help if you need it.
Here are some things you can check before a trip:
•Windshield Washer Fluid:Is the reservoir full?
Are all windows clean inside and outside?
•Wiper Blades:Are they in good shape?
•Fuel, Engine Oil, Other Fluids:Have you checked
all levels?
•Lamps:Are they all working? Are the lenses clean?
•Tires:They are vitally important to a safe,
trouble-free trip. Is the tread good enough for
long-distance driving? Are the tires all inflated to
the recommended pressure?
•Weather Forecasts:What is the weather outlook
along your route? Should you delay your trip a
short time to avoid a major storm system?
•Maps:Do you have up-to-date maps?
4-21

•Put on extra clothing or wrap a blanket around you.
If you have no blankets or extra clothing, make body
insulators from newspapers, burlap bags, rags, floor
mats — anything you can wrap around yourself or
tuck under your clothing to keep warm.
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 can not 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 your 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
your headlamps. Let the heater run for a while.

If the oil pressure light
appears on the instrument
cluster, it means you
need to check your engine
oil level right away.
For more information, seeOil Pressure Light on
page 3-42.
You should check your engine oil level regularly; this is
an added reminder.

When to Inspect the Engine Air
Cleaner/Filter
Inspect the engine air cleaner/filter every 15,000 miles
(25 000 km) and replace every 30,000 miles (50 000 km).
If you are driving in dusty/dirty conditions, inspect the
filter at each engine oil change.
How to Inspect the Engine Air
Cleaner/Filter
To inspect the engine air cleaner/filter remove the filter
from the vehicle and lightly shake the filter to release
loose dust and dirt. If the filter remains caked with dirt,
a new filter is required.
To inspect or replace the filter, do the following:
1. Open the latches that hold the cover on.
2. Lift off the cover.
3. Check or replace the engine air cleaner/filter.
4. Put the cover back on tightly and close the latches.
SeeUsing Your Maintenance Schedule on page 6-4
for replacement intervals.
{CAUTION:
Operating the engine with the air cleaner/lter
off can cause you or others to be burned.
The air cleaner not only cleans the air, it helps
to stop ame if the engine backres. If it is
not there and the engine backres, you could
be burned. Do not drive with it off, and be
careful working on the engine with the air
cleaner/lter off.
Notice:If the air cleaner/lter is off, a backre can
cause a damaging engine re. And, dirt can easily get
into your engine, which will damage it. Always have
the air cleaner/lter in place when you are driving.

Automatic Transaxle Fluid
It is not necessary to check the transaxle fluid level.
If a leak occurs, take the vehicle to the dealership
service department and have it repaired as soon as
possible. You may also have your fluid level checked
by your dealer or service center when you have your
oil changed.
Have your dealer or service center change both the fluid
and filter every 50,000 miles (83 000 km) if the vehicle
is mainly driven under one or more of these conditions:
•In heavy city traffic where the outside temperature
regularly reaches 90°F (32°C) or higher.
•In hilly or mountainous terrain.
•Uses such as found in taxi, police or delivery
service.
If you do not use your vehicle under any of these
conditions, the fluid and filter do not require changing.
Notice:Use of automatic transaxle uid labeled
other than ESSO LT71141 or TOTAL ATF H50235
may damage your vehicle, and the damages may
not be covered by your warranty. Always use
ESSO LT71141 or TOTAL ATF H50235 labeled
automatic transaxle uid.
Engine Coolant
The following explains your cooling system and how
to add coolant when it is low. If you have a problem with
engine overheating, seeEngine Overheating on
page 5-22.
A 50/50 mixture of clean, drinkable water and proper
coolant will:
•Give freezing protection down to−22°F (−30°C).
•Give boiling protection up to 268°F (131°C).
•Protect against rust and corrosion.
•Help keep the proper engine temperature.
•Let the warning lights and gages work as they
should.
What to Use
Use a 50/50 mixture ofclean, drinkable waterand coolant
that meets GM specification 1825M, which will not
damage aluminum parts. You can also use a recycled
coolant confirming to GM specification 1825M with a
complete coolant flush and refill. If you use this coolant
mixture, you do not need to add anything else.
