DIC Warnings and Messages
These messages appear if there is a problem detected
in one of your vehicle’s systems.
A message clears when the vehicle’s condition is no
longer present. To acknowledge a message and clear it
from the display, press and hold any of the DIC buttons.
If the condition is still present, the warning message
comes back on the next time the vehicle is turned off
and back on. With most messages, a warning chime
sounds when the message displays. Your vehicle may
have other warning messages.
AUTO (Automatic) LIGHTS OFF
This message displays if the automatic headlamp
system is disabled with the headlamp switch.
AUTO (Automatic) LIGHTS ON
This message displays if the automatic headlamp
system is enabled with the headlamp switch.
BRAKE FLUID
This message displays, while the ignition is on, when
the brake uid level is low. The brake system warning
light on the instrument panel cluster also comes on.
SeeBrake System Warning Light on page 3-27for
more information. Have the brake system serviced
by your dealer/retailer as soon as possible.
CHANGE OIL SOON
This message displays when the life of the engine oil
has expired and it should be changed.
When this message is acknowledged and cleared from
the display, the engine oil life system must still be
reset separately. SeeEngine Oil Life System on
page 5-19andScheduled Maintenance on page 6-4
for more information.
CHECK GAS CAP
This message displays if the fuel cap has not been fully
tightened. Recheck the fuel cap to make sure that it
is on properly. A few driving trips with the cap properly
installed should turn the message off.
CHECK TIRE PRESS (Pressure)
This message displays when the pressure in one or
more of the vehicle’s tires needs to be checked. If a tire
pressure message appears on the DIC, stop as soon
as you can. Have the tire pressures checked and set to
those shown on the Tire Loading Information label.
SeeTires on page 5-51,Loading Your Vehicle on
page 4-24, andInflation - Tire Pressure on page 5-58.
The DIC also shows the tire pressure values. See
DIC Operation and Displays on page 3-38. If the tire
pressure is low, the low tire pressure warning light
comes on. SeeTire Pressure Light on page 3-31.

Hydroplaning
Hydroplaning is dangerous. Water can build up
under your vehicle’s tires so they actually ride on the
water. This can happen if the road is wet enough
and you are going fast enough. When your vehicle is
hydroplaning, it has little or no contact with the road.
There is no hard and fast rule about hydroplaning.
The best advice is to slow down when the road is wet.
Other Rainy Weather Tips
Besides slowing down, other wet weather driving tips
include:
Allow extra following distance.
Pass with caution.
Keep windshield wiping equipment in good shape.
Keep the windshield washer uid reservoir lled.
Have good tires with proper tread depth. SeeTires
on page 5-51.
Before Leaving on a Long Trip
To prepare your vehicle for a long trip, consider having
it serviced by your dealer/retailer before departing.
Things to check on your own include:
Windshield Washer Fluid:Reservoir full? Windows
clean — inside and outside?
Wiper Blades:In good shape?
Fuel, Engine Oil, Other Fluids:All levels checked?
Lamps:Do they all work and are lenses clean?
Tires:Are treads good? Are tires in ated to
recommended pressure?
Weather and Maps:Safe to travel? Have up-to-date
maps?

Checking Engine Oil
It is a good idea to check the engine oil every time you
get fuel. In order to get an accurate reading, the oil
must be warm and the vehicle must be on level ground.
The engine oil dipstick handle is a yellow loop. See
Engine Compartment Overview on page 5-12for
the location of the engine oil dipstick.
1. Turn off the engine and give the oil several minutes
to drain back into the oil pan. If you do not do this,
the oil dipstick might not show the actual level.
2. Pull the dipstick and clean it with a paper towel or
cloth, then push it back in all the way. Remove it
again, keeping the tip down and check the level.

When to Add Engine Oil
If the oil is below the MIN (minimum) mark, add at least
one quart/liter of the recommended oil. This section
explains what kind of oil to use. For engine oil crankcase
capacity, seeCapacities and Specifications on
page 5-101.
Notice:Do not add too much oil. If the engine
has so much oil that the oil level gets above the
upper mark that shows the proper operating range,
the engine could be damaged.SeeEngine Compartment Overview on page 5-12for
the location of the engine oil ll cap.
Be sure to add enough oil to put the level somewhere
in the proper operating range. Push the dipstick all
the way back in when you are through.2.4L L4 Engine2.0L L4 Engine

What Kind of Engine Oil to Use
For Vehicles With the 2.0L L4 Engine
Look for three things:
GM4718M
Your vehicle’s engine requires a special oil meeting
GM Standard GM4718M, such as Mobil 1
®or
equivalent. Oils meeting this standard may be
identi ed as synthetic. However, not all synthetic
oils will meet this GM standard. Look for and use
only an oil that meets GM Standard GM4718M.Notice:If you use oils that do not have the
GM4718M Standard designation, you can cause
engine damage not covered by your warranty.
SAE 5W-30
As shown in the viscosity chart, SAE 5W-30 is best
for your vehicle.
These numbers on an oil container show its
viscosity, or thickness. Do not use other viscosity
oils such as SAE 20W-50.
Oils meeting these
requirements should
have the starburst
symbol on the container.
This symbol indicates
that the oil has been
certi ed by the
American Petroleum
Institute (API).
Look for this on the oil container, and use only those oils
that are identi ed as meeting GM Standard GM4718M
and have the starburst symbol on the front of the oil
container.
Your vehicle’s engine is lled at the factory with a
synthetic oil which meets all requirements for your
vehicle.
Substitute Engine Oil: When adding oil to maintain
engine oil level, oil meeting GM Standard GM4718M
may not be available.
5-17

If you are in an area of extreme cold, where
the temperature falls below−20°F (−29°C), it is
recommended that you use either an SAE 5W-30
synthetic oil or an SAE 0W-30 oil. Both provide easier
cold starting and better protection for the engine at
extremely low temperatures.
Engine Oil Additives
Do not add anything to the oil. The recommended oils
with the starburst symbol that meet GM Standard
GM6094M are all you need for good performance
and engine protection.
Engine Oil Life System
When to Change Engine Oil
Your vehicle has the Engine Oil Life System, a computer
system that lets you know when to change the engine oil
and lter. This is based on engine revolutions and engine
temperature, and not on mileage. Based on driving
conditions, the mileage at which an oil change will be
indicated can vary considerably. For the oil life system to
work properly, you must reset the system every time the
oil is changed.When the system has calculated that oil life has been
diminished, it will indicate that an oil change is necessary.
A CHANGE OIL SOON message will come on. SeeDIC
Warnings and Messages on page 3-40. Change the oil as
soon as possible within the next 600 miles (1 000 km).
It is possible that, if you are driving under the best
conditions, the oil life system might not indicate that an oil
change is necessary for over a year. However, the engine
oil and lter must be changed at least once a year and at
this time the system must be reset. Your dealer/retailer
has trained service people who will perform this work
using genuine parts and reset the system. It is also
important to check the oil regularly and keep it at
the proper level.
If the system is ever reset accidentally, you must
change the oil at 3,000 miles (5 000 km) since the
last oil change. Remember to reset the oil life system
whenever the oil is changed.
