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).

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, impaired driving,

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 see Tires
0364 and
Tire Pressure 0372.
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 safely exceed
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.”

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.

Winter Cover
If equipped, the winter cover
can be used to enhance
heater performance in
extremely cold conditions
below −0 °C (32 °F). The winter
cover installs over the grille
and restricts airflow to the
engine compartment.
Usage Guidelines
The winter cover should only
be used while operating the
vehicle in extremely cold
temperatures or in heavy
snow for extended periods. In
these temperatures, the
vehicle does not need a large
amount of air to properly cool
the engine. When more airflow
is required to cool the vehicle,
the winter cover should not be
used. The following usage
guidelines will allow adequate
airflow for proper radiator and
air cooler performance:
.Do not use the winter cover
if towing a trailer. The
vehicle may overheat if the
radiator is covered while
towing.
.Do not modify the cover. The
winter cover does not cover
some sections of the front
of the vehicle to provide
enough airflow.
.Keep the underside of the
winter cover as clean as
possible. Remove monthly or
as necessary and clean away
dust and debris.
.Do not use the winter cover
above −0 °C (32 °F).
Use only a mild soap to clean.
Do not use harsh soap, strong
detergents, or vinyl
protectant/sealant type
products as they may damage
the special finish. Allow the
winter cover to dry completely
before reinstalling.
Installation Instructions
When first trying to fit the
cover, it may appear to be
undersized but will stretch
during installation to ensure a
tight fit. The initial installation
of the cover is best performed
when the winter cover
is warm.
1. Center grille cover and make sure that it is
positioned correctly.
