.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, speeding up or braking.
.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.
Engine Coolant Temperature
Gauge
This gauge measures the temperature of the
vehicle's engine.
While driving under normal operating
conditions, if the red LED is illuminated, the
engine is too hot. Pull off the road, stop the
vehicle, and turn off the engine as soon as
possible.
Seat Belt Reminders
Driver Seat Belt Reminder Light
There is a driver seat belt reminder light on
the instrument cluster.
When the vehicle is started, this light
flashes and a chime may come on to remind
the driver to fasten their seat belt.
Then the light stays on solid until the belt is
buckled. This cycle may continue several
times if the driver remains or becomes
unbuckled while the vehicle is moving.
If the driver seat belt is buckled, neither the
light nor the chime comes on.
Front Passenger Seat Belt Reminder
Light
The vehicle may have a front passenger seat
belt reminder light near the passenger
airbag status indicator. SeePassenger
Sensing System 054.
When the vehicle is started, this light
flashes and a chime may come on to remind
passengers to fasten their seat belt.
Then the light stays on solid until the belt is
buckled. This cycle continues several times if
the front passenger remains or becomes
unbuckled while the vehicle is moving.
If the front passenger seat belt is buckled,
neither the chime nor the light comes on.
The front passenger seat belt reminder light
and chime may come on if an object is put
on the seat such as a briefcase, handbag,
grocery bag, laptop, or other electronic

Instruments and Controls 97
If the light is flashing :A malfunction has
been detected that could damage the
emission control system and increase vehicle
emissions. Diagnosis and service may be
required.
To help prevent damage, reduce vehicle
speed and avoid hard accelerations and
uphill grades.
If the light continues to flash, find a safe
place to park. Turn the vehicle off and wait
at least 10 seconds before restarting the
engine. If the light is still flashing, follow
the previous guidelines and see your dealer
for service as soon as possible.
If the light is on steady : A malfunction has
been detected. Diagnosis and service may be
required.
Check the following:
.A loose or missing fuel cap may cause
the light to come on. See Filling the Tank
0 247. A few driving trips with the cap
properly installed may turn the light off.
.Poor fuel quality can cause inefficient
engine operation and poor driveability,
which may go away once the engine is
warmed up. If this occurs, change the fuel brand. It may require at least one full
tank of the proper fuel to turn the light
off. See
Recommended Fuel 0246.
If the light remains on, see your dealer.
Emissions Inspection and Maintenance
Programs
If the vehicle requires an Emissions
Inspection/Maintenance test, the test
equipment will likely connect to the
vehicle's Data Link Connector (DLC).
The DLC is under the instrument panel to
the left of the steering wheel. Connecting
devices that are not used to perform an
Emissions Inspection/Maintenance test or to
service the vehicle may affect vehicle
operation. See Add-On Electrical Equipment
0 257. See your dealer if assistance is
needed.
The vehicle may not pass inspection if:
.The light is on when the engine is
running.
.The light does not come on when the
ignition is in Service Mode.
.Critical emission control systems have not
been completely diagnosed. If this
happens, the vehicle would not be ready
for inspection and might require
several days of routine driving before the
system is ready for inspection. This can
happen if the 12-volt battery has recently
been replaced or run down, or if the
vehicle has been recently serviced.
See your dealer if the vehicle will not pass
or cannot be made ready for the test.
Brake System Warning Light
MetricEnglish
This light should come on briefly when the
vehicle is turned on. If it does not come on
then, have it fixed so it will be ready to
warn you if there is a problem.

Driving Information
Driver Behavior
Driving is an important responsibility. Driver
behavior, the driving environment, and the
vehicle's design all affect how well a vehicle
performs.
Being aware of these factors can help in
understanding how the vehicle handles and
what can be done to avoid many types of
crashes, including a rollover crash.
Most serious injuries and fatalities to
unbelted occupants can be reduced or
prevented by the use of seat belts. In a
rollover crash, an unbelted person is
significantly more likely to die than a
person wearing a seat belt. In addition,
avoiding excessive speed, sudden or abrupt
turns, and drunken or aggressive driving can
help make trips safer and avoid the
possibility of a crash.
Driving Environment
Be prepared for driving in inclement
weather, at night, or during other times
where visibility or traction may be limited,
such as on curves, slippery roads, or hilly
terrain. Unfamiliar surroundings can also
have hidden hazards.
Vehicle Design
Utility vehicles have a significantly higher
rollover rate than other types of vehicles.
This is because they have a higher ground
clearance and a narrower track or shorter
wheelbase than passenger cars, which makes
them more capable for off-road driving.
While these design characteristics provide
the driver with a better view of the road,
these vehicles do have a higher center of
gravity than other types of vehicles.
A utility vehicle does not handle the same
as a vehicle with a lower center of gravity,
like a car, in similar situations.
Safe driver behavior and understanding of
the environment can help avoid a rollover
crash in any type of vehicle, including utility
vehicles.

Example 3
1.Vehicle Capacity Weight for
Example 3 = 453 kg (1,000 lbs).
2.Subtract Occupant Weight @ 91 kg
(200 lbs) × 5 = 453 kg (1,000 lbs).
3.Available Cargo Weight =
0 kg (0 lbs).
Refer to the vehicle's tire and loading
information label for specific
information about the vehicle's capacity
weight and seating positions. The
combined weight of the driver,
passengers, and cargo should never
exceed the vehicle's capacity weight.
Certification/Tire Label
Label Example
A vehicle-specific Certification/Tire label
is attached to the center pillar (B-pillar).
The label may show the size of the
vehicle's original tires and the inflation
pressures needed to obtain the gross
weight capacity of the vehicle. The label
shows the gross weight capacity of the
vehicle. This is called the Gross Vehicle
Weight Rating (GVWR). The GVWR
includes the weight of the vehicle, all
occupants, fuel, and cargo. The Certification/Tire label may also
show the maximum weights for the
front and rear axles, called the Gross
Axle Weight Rating (GAWR). To find out
the actual loads on the front and rear
axles, weigh the vehicle at a weigh
station. Your dealer can help with this.
Be sure to spread the load equally on
both sides of the centerline.
Caution
Overloading the vehicle may cause
damage. Repairs would not be covered by
the vehicle warranty. Do not overload the
vehicle.
{Warning
Things inside the vehicle can strike
and injure people in a sudden stop or
turn, or in a crash.
.Put things in the cargo area of the
vehicle. In the cargo area, put
them as far forward as possible.
Try to spread the weight evenly.

Warning (Continued)
.Never stack heavier things, like
suitcases, inside the vehicle so
that some of them are above the
tops of the seats.
.Do not leave an unsecured child
restraint in the vehicle.
.Secure loose items in the vehicle.
.Do not leave a seat folded down
unless needed.
Starting and Operating
New Vehicle Break-In
Caution
The vehicle does not need an elaborate
break-in. But it will perform better in the
long run if you follow these guidelines:
.Do not drive at any one constant
speed, fast or slow, for the first
800 km (500 mi). Do not make
full-throttle starts. Avoid downshifting
to brake or slow the vehicle.
(Continued)
Caution (Continued)
.Avoid making hard stops for the first
300 km (200 mi) or so. During this
time the new brake linings are not yet
broken in. Hard stops with new linings
can mean premature wear and earlier
replacement. Follow this breaking-in
guideline every time you get new
brake linings.
.Do not tow a trailer during break-in.
SeeTrailer Towing 0252 for the trailer
towing capabilities of the vehicle and
more information.
Following break-in, engine speed and load
can be gradually increased.
On new vehicles, the various mechanical and
electrical systems experience a “break-in”
period during the first 6,400 km
(4,000 miles) of routine driving. As the
vehicle is driven, the mechanical systems
adjust to provide optimal fuel economy and
transmission shift performance.
Electrical systems will adapt and calibrate
during the break-in period. A one-time
occurrence of clicks and similar vehicle
noises is normal during this process. Normal driving charges the vehicle’s battery
to achieve the best operation of the vehicle,
including fuel economy and the Stop/Start
System. See
Stop/Start System 0201.
Ignition Positions
This vehicle has pushbutton starting.
The remote key must be in the vehicle for
the system to operate. If the pushbutton
start is not working, the vehicle may be
near a strong radio antenna signal causing
interference to the Keyless Access system.
