110 Instruments and Controls
Uplevel English
When the ignition is on, the fuel
gauge shows about how much fuel
is left in the tank.
An arrow on the fuel gauge
indicates the side of the vehicle the
fuel door is on.
When the vehicle's fuel level
becomes low, a message appears
in the Driver Information Center
(DIC) and a single chime sounds.
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 will go back to
empty when the ignition is
turned off. Engine Oil Temperature

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
(Continued) Warning (Continued) 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

handling, acceleration, braking,
durability, and fuel economy.

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
