INSTRUMENTS AND CONTROLS 117
When the ignition is on, the fuel
gauge indicates about how much fuel
is left in the tank.
There is an arrow near the fuel gauge
pointing to the side of the vehicle the
fuel door is on.
When the indicator nears empty, the
low fuel light comes on. There still is
a little fuel left, but the vehicle should
be refueled soon.
Here are four things that some owners
ask about. None of these show a
problem with the fuel gauge:
.At the service station, the fuel
pump shuts off before the gauge
reads full.
. It takes a little more or less fuel to
fill up than the gauge indicated.
For example, the gauge may have
indicated the tank was half full,
but it actually took a little more or
less than half the tank's capacity
to fill the tank.
. The gauge moves a little while
turning a corner or speeding up. .
The gauge takes a few seconds to
stabilize after the ignition is
turned on, and goes back to empty
when the ignition is turned off.
Boost Gauge (Performance
Configuration Only)
This gauge indicates boost under
heavier throttle.
It displays the air pressure level in the
intake manifold before it enters the
engine's combustion chamber.
The gauge is automatically centered at
zero every time the engine is started.
Actual boost is displayed from this zero point. Changes in ambient
pressure, such as driving in mountains
and changing weather, will slightly
change the zero reading.

{Warning
Fuel vapors and fuel fires burn
violently and can cause injury or
death.
Follow these guidelines to help
avoid injuries to you and others:
. Read and follow all the
instructions on the fuel pump
island.

unattended.
. Avoid using electronic devices
while refueling.
. Do not re-enter the vehicle
while pumping fuel.
. Keep children away from the
fuel pump and never let
children pump fuel.
. Before touching the fill
nozzle, touch a metallic
object to discharge static
electricity from your body.
. Fuel can spray out if the fill
nozzle is inserted too quickly.
This spray can happen if the
tank is nearly full, and is
more likely in hot weather.
Insert the fill nozzle slowly
and wait for any hiss noise to
stop before beginning to
flow fuel. The fuel door unlocks when the
vehicle doors are unlocked. See

have a fuel cap. Fully insert and latch
the fill nozzle, then begin fueling.

the trunk.
2. Insert and latch the funnel into the capless fuel system.
{Warning
Attempting to refuel from a
portable fuel container without

Trailer Towing
General Towing
Information
Only use towing equipment that has
been designed for the vehicle. Contact
your dealer or trailering dealer for
assistance with preparing the vehicle
to tow a trailer. Read the entire
section before towing a trailer.
To tow a disabled vehicle, see Towing
the Vehicle 0346. To tow the vehicle
behind another vehicle such as a
motor home, see Recreational Vehicle
Towing 0348.
Driving Characteristics and
Towing Tips
{Warning
You can lose control when towing a
trailer if the correct equipment is
not used or the vehicle is not driven
properly. For example, if the trailer
is too heavy or the trailer brakes are

inadequate for the load, the vehicle
may not stop as expected. You and
others could be seriously injured.
The vehicle may also be damaged,
and the repairs would not be
covered by the vehicle warranty.
Pull a trailer only if all the steps in
this section have been followed. Ask
your dealer for advice and
information about towing a trailer
with the vehicle.
Driving with a Trailer
Trailering is different than just driving
the 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.
The following information has many
time-tested, important trailering tips
and safety rules. Many of these are
