Here are five things that some
owners ask about. All these things
are normal and do not indicate that
anything is wrong with the fuel
gauge.
.At the service station, the gas
pump shuts off before the gauge
reads the full.
.It takes a little more or less fuel
to fill up than the gauge
indicated. For example, the
gauge may have indicated half
full, but it took a little more or
less than half of the tank's
capacity to fill the tank.
.The gauge pointer may move
while cornering, braking or
speeding up.
.The gauge may not indicate the
tank is empty when the ignition
is turned off.
.The gauge reading may change
slightly within the first several
minutes after starting the
vehicle.See
“DIC Operation and Displays”
in Driver Information Center (DIC)
on page 5‑25 for more information.
Boost Gauge (ZR1)
Metric
English
This gauge indicates vacuum during
light to moderate throttle and 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 vacuum or 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.

This light comes on during a
malfunction in one of two ways:
Light Flashing:A misfire condition
has been detected. A misfire
increases vehicle emissions and
could damage the emission control
system on the vehicle. Diagnosis
and service might be required.
The following can prevent more
serious damage to the vehicle:
.Reduce vehicle speed.
.Avoid hard accelerations.
.Avoid steep uphill grades.
If the light continues to flash, find a
safe place to stop and park the
vehicle. Turn the vehicle off, wait at
least 10 seconds, and restart the
engine. If the light is still flashing,
follow the previous steps and see
your dealer for service as soon as
possible.
Light On Steady: An emission
control system malfunction has
been detected on the vehicle.
Diagnosis and service might be
required. The following may correct an
emission control system
malfunction:
.Check that the fuel cap is fully
installed. See
Filling the Tank on
page 9‑47. The diagnostic
system can determine if the fuel
cap has been left off or
improperly installed. A loose or
missing fuel cap allows fuel to
evaporate into the atmosphere.
A few driving trips with the cap
properly installed should turn the
light off.
.Check that good quality fuel is
used. Poor fuel quality causes
the engine not to run as
efficiently as designed and may
cause: stalling after start-up,
stalling when the vehicle is
changed into gear, misfiring,
hesitation on acceleration,
or stumbling on acceleration.
These conditions might go away
once the engine is warmed up. If one or more of these conditions
occurs, change the fuel brand used.
It may require at least one full tank
of the proper fuel to turn the light off.
See
Recommended Fuel on
page 9‑45.
If none of the above have made the
light turn off, your dealer can check
the vehicle. The dealer has the
proper test equipment and
diagnostic tools to fix any
mechanical or electrical problems
that might have developed.Emissions Inspection and
Maintenance Programs
Depending on where you live, your
vehicle may be required to
participate in an emission control
system inspection and maintenance
program. For the inspection, the
emission system test equipment will
likely connect to the vehicle's Data
Link Connector (DLC).

8-4 Climate Controls
^(Air Conditioning Off):Press to
turn the air conditioning compressor
off. Press AUTO to return to
automatic operation. When in
AUTO, the air conditioning
compressor comes on automatically,
as needed.
Air conditioning does not operate at
temperatures below about 2°C to
4°C (35°F to 40°F). In temperatures
above 4°C (40°F), the air
conditioning cannot be turned off in
defrost and defog, as it helps to
remove moisture from the vehicle.
It also helps to keep the windows
clear.
You may notice a slight change in
engine performance when the air
conditioning compressor shuts off
and turns on again. This is normal.
The system is designed to make
adjustments to help with fuel
economy while still maintaining the
selected temperature.
On hot days, open the windows to
let hot inside air escape; then close
them. This helps to reduce the time it takes for the vehicle to cool down.
It also helps the system to operate
more efficiently.
For quick cool down on hot days
press the AUTO button and adjust
the temperature to a cool,
comfortable setting. To achieve
maximum cool down, do the
following:
1. Select
Hmode.
2. Press
?.
3. Select the a/c on.
4. Select the coolest temperature.
5. Select the highest fan speed.
Using these settings together for
long periods of time may cause the
air inside of your vehicle to become
too dry. To prevent this from
happening, after the air in the
vehicle has cooled, turn the
recirculation mode off.
The air conditioning system
removes moisture from the air, so a
small amount of water might drip under the vehicle while idling or
after turning off the engine. This is
normal.
?(Recirculation):
Press to turn
the recirculation mode on or off. An
indicator light comes on to show
that recirculation is on. This mode
prevents outside air from entering
your vehicle. It can be used to
prevent outside air and odors from
entering your vehicle and to help
cool the air inside your vehicle more
quickly. Recirculation mode is not
available in defrost or defog mode.
Sensors
The solar sensor on the vehicle
monitors the solar heat and uses
the information to maintain the
selected temperature when
operating in AUTO mode by
automatically adjusting the
temperature, fan speed, and air
delivery system. The system may
also supply cooler air to the side of
the vehicle facing the sun. The
recirculation mode will also be
activated, as necessary. Do not

9-12 Driving and Operating
If it takes some time for help to
arrive, now and then when you run
the engine, push the accelerator
pedal slightly so the engine runs
faster than the idle speed. This
keeps the battery charged to restart
the vehicle and to signal for help
with the headlamps. Do this as little
as possible to save fuel.
If the Vehicle Is Stuck
Slowly and cautiously spin the
wheels to free the vehicle when
stuck in sand, mud, ice, or snow.
If stuck too severely for the traction
system to free the vehicle, turn the
traction system off and use the
rocking method. SeeTraction
Control System (TCS) on
page 9‑34.
{WARNING
If the vehicle's tires spin at high
speed, they can explode, and you
or others could be injured. The
vehicle can overheat, causing an
engine compartment fire or other
damage. Spin the wheels as little
as possible and avoid going
above 56 km/h (35 mph).
Rocking the Vehicle to Get
it Out
Turn the steering wheel left and
right to clear the area around the
front wheels. Turn off any traction
system. Shift back and forth
between R (Reverse) and a low
forward gear, spinning the wheels
as little as possible. To prevent
transmission wear, wait until the
wheels stop spinning before shifting
gears. Release the accelerator
pedal while shifting, and press
lightly on the accelerator pedal
when the transmission is in gear. Slowly spinning the wheels in the
forward and reverse directions
causes a rocking motion that could
free the vehicle. If that does not get
the vehicle out after a few tries, it
might need to be towed out. If the
vehicle does need to be towed out,
see
Towing the Vehicle on
page 10‑79.
Vehicle Load Limits
It is very important to know how
much weight your vehicle can
carry. This weight is called the
vehicle capacity weight and
includes the weight of all
occupants, cargo and all
nonfactory-installed options.
Two labels on your vehicle show
how much weight it may
properly carry, the Tire and
Loading Information label and
the Certification label.

Example 2
A. Vehicle Capacity Weight for Example 2 = 181 kg (400 lbs)
B. Subtract Occupant Weight @ 68 kg (150 lbs) × 2 = 136 kg
(300 lbs)
C. Available Cargo Weight = 45 kg (100 lbs)Example 3
A. Vehicle Capacity Weight for Example 3 = 181 kg (400 lbs)
B. Subtract Occupant Weight @ 91 kg (200 lbs) × 2 = 181 kg
(400 lbs)
C. Available Cargo Weight = 0 kg (0 lbs)
Refer to your vehicle's Tire and
Loading Information label for
specific information about your
vehicle's capacity weight and
seating positions. The combined weight of the driver, passengers
and cargo should never exceed
your vehicle's capacity weight.
Certification Label
A vehicle-specific Certification
label is attached to the rear
edge of the driver door. It tells
you the gross weight capacity of
your vehicle, called the Gross
Vehicle Weight Rating (GVWR).
The GVWR includes the weight
of the vehicle, all occupants, fuel
and cargo. Never exceed the

nozzle. Clean fuel from painted
surfaces as soon as possible. See
Exterior Care on page 10‑79.
When replacing the fuel cap, turn it
clockwise until it clicks. Make sure
the cap is fully installed. The
diagnostic system can determine if
the fuel cap has been left off or
improperly installed. This would
allow fuel to evaporate into the
atmosphere. SeeMalfunction
Indicator Lamp on page 5‑18.
The CHECK GAS CAP message
displays on the Driver Information
Center (DIC) if the fuel cap is not
properly installed. See Fuel System
Messages on page 5‑40 for more
information.
{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. Notice:
If you need a new fuel
cap, be sure to get the right type.
Your dealer can get one for you.
If you get the wrong type, it may
not fit properly. This may cause
the malfunction indicator lamp to
light and may damage the fuel
tank and emissions system. See
Malfunction Indicator Lamp on
page 5‑18.
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. You or others could be
badly burned and the vehicle
could be damaged. Always:
.Use approved fuel
