INSTRUMENTS AND CONTROLS 123
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)
Metric
English
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.

Filling the Tank
{Warning
Fuel vapors and fuel fires burn
violently and can cause injury or
death.. To help avoid injuries to you
and others, read and follow
all the instructions on the
fuel pump island.
. Turn off the engine when
refueling.
. Keep sparks, flames, and
smoking materials away
from fuel.
. Do not leave the fuel pump
unattended.
. Do not use a cell phone while
refueling.
. Do not reenter the vehicle
while pumping fuel.
. Keep children away from the
fuel pump and never let
children pump fuel.
(Continued)
Warning (Continued)
.Fuel can spray out if the
refueling nozzle is inserted
too quickly. This spray can
happen if the tank is nearly
full, and is more likely in hot
weather. Insert the refueling
nozzle slowly and wait for any
hiss noise to stop prior to
beginning to flow fuel.
To open the fuel door, push and
release the rearward center edge of
the door. The vehicle has a capless refueling
system and does not have a fuel cap.
The filling nozzle must be fully
inserted and latched prior to starting
fuel flow.
{Warning
Overfilling the fuel tank by more
than three clicks of a standard fill
nozzle may cause:
. Vehicle performance issues,
including engine stalling and
damage to the fuel system.
. Fuel spills.
. Potential fuel fires.
Be careful not to spill fuel. Wait a few
seconds after you have finished
pumping before removing the nozzle.
Clean fuel from painted surfaces as
soon as possible. See Exterior Care
0 307.

DRIVING AND OPERATING 225
{Warning
If a fire starts while you are
refueling, do not remove the nozzle.
Shut off the flow of fuel by shutting
off the pump or by notifying the
station attendant. Leave the area
immediately.
Filling the Tank with a Portable
Gas Can
If the vehicle runs out of fuel and
must be filled from a portable gas can:
1. Locate the capless funnel adapter from under the carpet in
the trunk.
If this is a professional vehicle,
see the Coachbuilder’s Owner
Manual for funnel adapter
location. 2. Insert and latch the funnel into
the capless fuel system.
{Warning
Attempting to refuel without using
the funnel adapter may cause fuel
spillage and damage the capless
fuel system. This could cause a fire
and you or others could be badly
burned and the vehicle could be
damaged.
3. Remove and clean the funnel adapter and return to the storage
location.
Filling a Portable Fuel
Container
{Warning
Filling a portable fuel container
while it is in the vehicle can cause
fuel vapors that can ignite either by
static electricity or other means.
(Continued)
Warning (Continued)
You or others could be badly
burned and the vehicle could be
damaged. Always:
. Use approved fuel containers.
. Remove the container from
the vehicle, trunk, or pickup
bed before filling.
. Place the container on the
ground.
. Place the nozzle inside the fill
opening of the container
before dispensing fuel, and
keep it in contact with the fill
opening until filling is
complete.
. Fill the container no more
than 95% full to allow for
expansion.
. Do not smoke, light matches,
or use lighters while
pumping fuel.
. Avoid using cell phones or
other electronic devices.
