The fog lamp light will
come on when the fog
lamps are in use.
The light will go out when the fog lamps are turned off.
SeeFog Lamps on page 3-14for more information.
Highbeam On Light
This light comes on when
the high-beam headlamps
are in use.

Fuel Gage
Your fuel gage tells you
about how much fuel
you have left.
Here are four things that some owners ask about.
None of these show a problem with your fuel gage:
At the service station, the gas pump shuts off before
the gage reads full.
It takes a little more or less fuel to ll up than the
gage indicated. For example, the gage may have
indicated the tank was half full, but it actually took a
little more or less than half the tank’s capacity to
ll the tank.
The gage moves a little when you turn a corner or
speed up.
The gage doesn’t go back to empty when you turn
off the ignition.
For your fuel tank capacity, seeCapacities and
Specifications on page 5-112.

Press the information button until FUEL RANGE
displays. This mode shows the remaining distance you
can drive without refueling in either miles (mi) or
kilometers (km). It is based on fuel economy and the
fuel remaining in the tank.
When the fuel level is low, FUEL RANGE LOW displays.
The fuel economy data used to determine fuel range
is an average of recent driving conditions. As your
driving conditions change, this data is gradually updated.
The FUEL RANGE mode cannot be reset.
MPG (L/100 KM) AVG (Average)
Press the information button until MPG (L/100 KM) AVG
displays. This mode shows how many miles per
gallon (mpg) or liters per 100 kilometers (L/100 km)
your vehicle is getting based on current and past driving
conditions.
To reset the average fuel economy, press and hold the
reset button while MPG (L/100 KM) AVG is displayed.
Average fuel economy is then calculated starting from
that point. If the average fuel economy is not reset, it is
continually updated each time you drive.
MPG (L/100 KM) INST (Instantaneous)
Press the information button until MPG (L/100 KM) INST
displays. This mode shows the current fuel economy
at a particular moment and changes frequently as
driving conditions change. This mode shows the
instantaneous fuel economy in miles per gallon (mpg) or
liters per 100 kilometers (L/100 km). Unlike average
fuel economy, this screen cannot be reset.

{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 cannot 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 the 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 the 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 the headlamps. Let the heater run for
a while.
Then, shut the engine off and close the window almost
all the way to preserve the heat. Start the engine again
and repeat this only when you feel really uncomfortable
from the cold. But do it as little as possible. Preserve the
fuel as long as you can. To help keep warm, you can get
out of the vehicle and do some fairly vigorous exercises
every half hour or so until help comes.

Your vehicle can tow a trailer if it is equipped with the
proper trailer towing equipment. If your vehicle is not
equipped as stated above, do not tow a trailer. To identify
the trailering capacity of your vehicle, you should read the
information in “Weight of the Trailer” that appears later in
this section. Trailering is different than just driving your
vehicle by itself. Trailering means changes in handling,
acceleration, braking, durability and fuel economy.
Successful, safe trailering takes correct equipment, and it
has to be used properly.
That is the reason for this part. In it are many
time-tested, important trailering tips and safety rules.
Many of these are important for your safety and that of
your passengers. So please read this section carefully
before you pull a trailer.
Load-pulling components such as the engine,
transmission, wheel assemblies and tires are forced to
work harder against the drag of the added weight.
The engine is required to operate at relatively higher
speeds and under greater loads, generating extra heat.
Also, the trailer adds considerably to wind resistance,
increasing the pulling requirements.If You Do Decide To Pull A Trailer
If you do, here are some important points:
There are many different laws, including speed limit
restrictions, having to do with trailering. Make sure
your rig will be legal, not only where you live but
also where you will be driving. A good source for this
information can be state or provincial police.
Consider using a sway control. You can ask a hitch
dealer about sway controls.
Do not tow a trailer at all during the rst 1,000 miles
(1 600 km) your new vehicle is driven. Your engine,
axle or other parts could be damaged.
Then, during the rst 500 miles (800 km) that you tow
a trailer, do not drive over 50 mph (80 km/h) and do
not make starts at full throttle. This helps your engine
and other parts of your vehicle wear in at the
heavier loads.
Obey speed limit restrictions when towing a trailer.
Do not drive faster than the maximum posted speed
for trailers, or no more than 55 mph (90 km/h), to
save wear on your vehicle’s parts.
Do not tow when the outside air temperature is
above 100°F (38°C).
Do not tow more than 1,000 miles (1 600 km)
per year.

If you want to do some of your own service work,
you should use the proper service manual. It tells
you much more about how to service your vehicle
than this manual can. To order the proper service
manual, seeService Publications Ordering Information
on page 7-16.
Your vehicle has an airbag system. Before attempting
to do your own service work, seeServicing Your
Airbag-Equipped Vehicle on page 1-66.
You should keep a record with all parts receipts and
list the mileage and the date of any service work
you perform. SeeMaintenance Record on page 6-16.
Adding Equipment to the
Outside of Your Vehicle
Things you might add to the outside of your vehicle
can affect the airow around it. This can cause
wind noise and can affect fuel economy and windshield
washer performance. Check with your dealer/retailer
before adding equipment to the outside of your vehicle.
Fuel
Use of the recommended fuel is an important part of
the proper maintenance of your vehicle. To help
keep the engine clean and maintain optimum vehicle
performance, we recommend the use of gasoline
advertised as TOP TIER Detergent Gasoline.
The 8th digit of the Vehicle Identication Number (VIN)
shows the code letter or number that identies your
vehicle’s engine. The VIN is at the top left of the
instrument panel. SeeVehicle Identification Number
(VIN) on page 5-104.
Gasoline Octane
If your vehicle has the 2.2L L4 engine (VIN Code F),
use regular unleaded gasoline with a posted octane
rating of 87 or higher. If the octane rating is less than 87,
you might notice an audible knocking noise when you
drive, commonly referred to as spark knock. If this
occurs, use a gasoline rated at 87 octane or higher as
soon as possible. If you are using gasoline rated at
87 octane or higher and you hear heavy knocking,
the engine needs service.
