116 INSTRUMENTS AND CONTROLS
Caution
Modifications to the engine,
transmission, exhaust, intake,
or fuel system, or the use of
replacement tires that do not meet
the original tire specifications, can
cause this light to come on. This
could lead to costly repairs not
covered by the vehicle warranty.
This could also affect the vehicle’s
ability to pass an Emissions
Inspection/Maintenance test. See
Accessories and Modifications0243.
If the light is f lashing : 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 towing a trailer, reduce the amount
of cargo being hauled as soon as
possible. 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:
. If fuel has been added to the
vehicle using the capless fuel
funnel adapter, make sure that it
has been removed. See “Filling the
Tank with a Portable Gas Can ”
under Filling the Tank 0227. The
diagnostic system can detect if the
adapter has been left installed in
the vehicle, allowing fuel to
evaporate into the atmosphere.
A few driving trips with the
adapter removed may turn off the
light.
. 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 0226.
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

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.

positions (1), and the maximum
vehicle capacity weight (2) in
kilograms and pounds.
The Tire and Loading Information
label also shows the size of the
original equipment tires (3) and
the recommended cold tire
inflation pressures (4). For more
information on tires and inflation
seeTires 0272 and
Tire Pressure 0279.
There is also important loading
information on the vehicle
Certification/Tire label. It may
show the Gross Vehicle Weight
Rating (GVWR) and the Gross Axle
Weight Rating (GAWR) for the
front and rear axle. See
“Certification/Tire Label” later in
this section.
“Steps for Determining Correct Load
Limit–
1.
Locate the statement "The
combined weight of
occupants and cargo should never exceed XXX kg or
XXX lbs." on your vehicle’s
placard.
2.Determine the combined
weight of the driver and
passengers that will be riding
in your vehicle.
3.Subtract the combined weight
of the driver and passengers
from XXX kg or XXX lbs.
4.The resulting figure equals
the available amount of cargo
and luggage load capacity. For
example, if the "XXX" amount
equals 1400 lbs. and there
will be five 150 lb passengers
in your vehicle, the amount
of available cargo and luggage
load capacity is 650 lbs.
(1400-750 (5 x 150) =
650 lbs.)
5.Determine the combined
weight of luggage and cargo
being loaded on the vehicle.
That weight may not safelyexceed the available cargo
and luggage load capacity
calculated in Step 4.
6.If your vehicle will be towing
a trailer, load from your
trailer will be transferred to
your vehicle. Consult this
manual to determine how
this reduces the available
cargo and luggage load
capacity of your vehicle.”
See Trailer Towing 0233 for
important information on towing
a trailer, towing safety rules and
trailering tips.

the parking brake is fully released
and the brake warning light is off
before driving.
Automatic EPB Release
The EPB will automatically release if
the vehicle is running, placed into
gear, and an attempt is made to drive away. Avoid rapid acceleration when
the EPB is applied, to preserve parking
brake lining life.
If parking on a hill, or if the vehicle is
pulling a trailer, see
Driving
Characteristics and Towing Tips 0230.
Brake Assist
Brake Assist detects rapid brake pedal
applications due to emergency braking
situations and provides additional
braking to activate the Antilock Brake
System (ABS) if the brake pedal is not
pushed hard enough to activate ABS
normally. Minor noise, brake pedal
pulsation, and/or pedal movement
during this time may occur. Continue
to apply the brake pedal as the driving
situation dictates. Brake Assist
disengages when the brake pedal is
released.

warning triangle with a left or right
pointing arrow on the infotainment
display to warn of traffic coming from
the left or right. This system detects
objects coming from up to 20 m (65 ft)
from the left or right side of the
vehicle. When an object is detected,
either three beeps sound from the left
or right or three Safety Alert Seat
pulses occur on the left or right side,
depending on the direction of the
detected vehicle.
Use caution while backing up when
towing a trailer, as the RCTA
detection zones that extend out from
the back of the vehicle do not move
further back when a trailer is towed. See
