The fuel gauge may:
.Take a little more, or less
fuel to fill up than it
indicates. For example, the
gauge may have indicated
the tank is half full, but it
actually will take a little
more, or less than half the
tank's capacity to fill
the tank.
.Moves a little while turning a
corner, speeding up,
or braking.
.Take a few seconds to
stabilize after the ignition is
turned on and goes back to
empty when the ignition is
turned off.
These are normal conditions,
none of which indicate a
problem with the fuel gauge.
Engine Coolant
Temperature Gauge
Metric
English 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

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
Modifications0327.
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 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 0311. 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 0310.
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).

and 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.
Driving for Better
Fuel Economy
Driving habits can affect fuel
mileage. Here are some driving
tips to get the best fuel
economy possible.
.Set the climate controls to
the desired temperature
after the engine is started,
or turn them off when not
required.
.On AWD vehicles, use Tour
Mode when conditions
permit.
.Avoid fast starts and
accelerate smoothly.
.Brake gradually and avoid
abrupt stops.
.Avoid idling the engine for
long periods of time.
.When road and weather
conditions are appropriate,
use cruise control.
.Always follow posted speed
limits or drive more slowly
when conditions require.
.Keep vehicle tires properly
inflated.
.Combine several trips into a
single trip.
.Replace the vehicle's tires
with the same TPC Spec
number molded into the
tire's sidewall near the size.
.Follow recommended
scheduled maintenance.
Distracted Driving
Distraction comes in many
forms and can take your focus
from the task of driving.
Exercise good judgment and
do not let other activities
divert your attention away
from the road. Many local

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 inflationpressures 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.
.Never stack heavier
things, like suitcases,
inside the vehicle so
that some of them are
above the tops of the
seats.

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(Continued)
Caution (Continued)
full-throttle starts. Avoid
downshifting to brake or
slow the vehicle.
.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. See Trailer
Towing0318 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 mi) 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 0249.

Trailer Towing
Caution
Towing a trailer improperly
can damage the vehicle and
result in costly repairs not
covered by the vehicle
warranty. To tow a trailer
correctly, follow the
directions in this section and
see your dealer for
important information about
towing a trailer with the
vehicle. Trailering is different than just
driving the vehicle by itself.
Trailering means changes in
handling, acceleration, braking,
durability, and fuel economy.
Successful, safe trailering
takes 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 important
for your safety and that of
your passengers. Read this
section carefully before pulling
a trailer.Trailer Weight
{Warning
Never exceed the towing
capacity for your vehicle.
Safe trailering requires
monitoring the weight, speed,
altitude, road grades, outside
temperature, dimensions of
the front of the trailer, and
how frequently the vehicle is
used to tow a trailer.
Trailer Weight Ratings
When towing a trailer, the
combined weight of the
vehicle, vehicle contents,
trailer, and trailer contents
must be below all of the
maximum weight ratings for
the vehicle including:
.Gross Combined Weight
Rating (GCWR)
.Gross Vehicle Weight
Rating (GVWR)
.Maximum Trailer Weight
Rating
.Gross Axle Weight
Rating-Rear (GAWR-RR)
.Maximum Trailer Tongue

See“Weight-Distributing Hitch
Adjustment” under Towing
Equipment 0322 to determine
if equalizer bars are required
to obtain the maximum trailer
weight rating.
See “Trailer Brakes” under
Towing Equipment 0322 to
determine if brakes are
required based on the trailer
weight.
The only way to be sure the
weight is not exceeding any of
these ratings is to weigh the
tow vehicle and trailer
combination, fully loaded for
the trip, getting individual
weights for each of these
items.
{Warning
You and others could be
seriously injured or killed if
the trailer is too heavy or
the trailer brakes are
inadequate for the load. The
vehicle may be damaged,

Warning (Continued)
and the repairs would not be
covered by the vehicle
warranty.
Only tow a trailer if all the
steps in this section have
been followed. Ask your
dealer for advice and
information about towing a
trailer.
Gross Combined Weight
Rating (GCWR)
GCWR is the total allowable
weight of the completely
loaded vehicle and trailer
including any fuel, passengers,
cargo, equipment, and
accessories. Do not exceed
the GCWR for your vehicle.
The GCWR for the vehicle is
on the Tow Rating Chart
following.
Gross Vehicle Weight
Rating (GVWR)
For information about the
vehicle's maximum load
capacity, see Vehicle Load
Limits0242. When calculating
the GVWR with a trailer
attached, the trailer tongue
weight must be included as
part of the weight the vehicle
is carrying.
Maximum Trailer Weight
The maximum trailer weight
rating is calculated assuming
the tow vehicle has a driver, a
front seat passenger, and all
required trailering equipment.
This value represents the
heaviest trailer the vehicle can
tow, but it may be necessary
to reduce the trailer weight to
stay within the GCW, GVWR,
maximum trailer tongue load,
or GAWR-RR for the vehicle.
Use the tow rating chart to
determine how much the
trailer can weigh, based on the
vehicle model and options.

engine vehicles
.Reduced range for
electric vehicles
Overinflated tires, or tires
that have too much air,
can result in:
.Unusual wear
.Poor handling
.Rough ride
.Needless damage from
road hazards
The Tire and Loading
Information label on the
vehicle indicates the
original equipment tires
and the correct cold tire
inflation pressures. The recommended pressure is
the minimum air pressure
needed to support the
vehicle's maximum load
carrying capacity. See
Vehicle Load Limits
0242.
How the vehicle is loaded
affects vehicle handling
and ride comfort. Never
load the vehicle with more
weight than it was
designed to carry.
When to Check
Check the pressure of the
tires once a month or more.
Do not forget the spare,
if the vehicle has one. The
compact spare cold tire
pressure should be at
420 kPa (60 psi). See
Compact Spare Tire 0404. How to Check
Use a good quality
pocket-type gauge to
check tire pressure. Proper
tire inflation cannot be
determined by looking at
the tire. Check the tire
inflation pressure when the
tires are cold, meaning the
vehicle has not been driven
for at least three hours or
no more than 1.6 km (1 mi).
Remove the valve cap from
the tire valve stem. Press
the tire gauge firmly onto
the valve to get a pressure
measurement. If the cold
tire inflation pressure
matches the recommended
pressure on the Tire and
Loading Information label,
no further adjustment is
necessary. If the inflation
