Instrument Cluster Descriptions
1. Speedometer• Indicates vehicle speed.
2. Fuel Gauge
• The pointer shows the level of fuel in the fuel tankwhen the ignition switch is in the ON/RUN position.
• The fuel pump arrow symbol points to the side of the vehicle where the fuel door is located.
3. Temperature Gauge

• The temperature gauge shows engine coolant tempera-ture. Any reading within the normal range indicates that
the engine cooling system is operating satisfactorily.

• The pointer will likely indicate a higher temperature when driving in hot weather or up mountain grades. It
should not be allowed to exceed the upper limits of the
normal operating range.
WARNING!
A hot engine cooling system is dangerous. You or others
could be badly burned by steam or boiling coolant. You
may want to call an authorized dealer for service if your
vehicle overheats. If you decide to look under the hood
yourself, refer to “Cooling System Pressure Cap” in
“Servicing And Maintenance” and follow the warnings
under the Cooling System Pressure Cap paragraph.
CAUTION!
Driving with a hot engine cooling system could damage
your vehicle. If the temperature gauge reads “H,” pull
over and stop the vehicle. Idle the vehicle with the air
conditioner turned off until the pointer drops back into
the normal range. If the pointer remains on the “H,” turn
the engine off immediately and call an authorized dealer
for service.

NOTE:
The range depends on several factors: driving style, type of
route (freeway, residential, mountain roads, etc.), conditions
of use of the vehicle (load, tire pressure, etc.). Trip planning
must take into account the above notes.
Travel Distance
This value shows the distance covered since the last reset.
Average Fuel Consumption
This value shows the approximate average consumption
since the last reset.
Current Fuel Consumption
This indicates the fuel consumption. The value is constantly
updated. The message “----” will appear on the display if the
vehicle is parked with the engine running.
Average Speed
This value shows the vehicle's average speed as a function of
the overall time elapsed since the last reset.
Travel Time
This value shows the time elapsed since the last reset.WARNING LIGHTS AND MESSAGES

The warning/indicator lights will illuminate in the instrument
panel together with a dedicated message and/or acoustic signal
when applicable. These indications are indicative and precau-
tionary and as such must not be considered as exhaustive and/
or alternative to the information contained in the Owner’s
Manual, which you are advised to read carefully in all cases.
Always refer to the information in this chapter in the event of a
failure indication. All active telltales will display first if appli -
cable. The system check menu may appear different based upon
equipment options and current vehicle status. Some telltales are
optional and may not appear.

Red Warning Lights
Air Bag Warning Light

This light will turn on for four to eight seconds as a bulb
check when the ignition is placed in the ON/RUN or
MAR/ON/RUN position. If the light is either not on
during startup, stays on, or turns on while driving, have the
system inspected at an authorized dealer as soon as possible.
This light will illuminate with a single chime when a fault with
the Air Bag Warning Light has been detected, it will stay on until
the fault is cleared. If the light comes on intermittently or
remains on while driving, have an authorized dealer service the
vehicle immediately.

GETTING TO KNOW YOUR INSTRUMENT PANEL 89
Low Fuel Warning LightWhen the fuel level reaches approximately 2–3 gal
(9–11 L) this light will turn on, and remain on until
fuel is added.
Generic Warning Light The Generic Warning Light will illuminate if any of
the following conditions occur: Engine Oil Pressure
Sensor Failure, External Light Failure, Parking
Sensor Failure, Fuel Cut-Off Fail/Intervention, Generic
Failure on Trailer, or Air Bag telltale recovery.
The telltale will blink in case of an Air Bag Warning Light
Failure. Contact an authorized dealer immediately for
service.
Tire Pressure Monitoring System (TPMS) Warning Light
The warning light switches on and a message is
displayed to indicate that the tire pressure is lower
than the recommended value and/or that slow pres -
sure loss is occurring. In these cases, optimal tire duration
and fuel consumption may not be guaranteed. Should one or more tires be in the condition mentioned
above, the display will show the indications corresponding
to each tire.
Each tire, including the spare (if provided), should be
checked monthly when cold and inflated to the inflation
pressure recommended by the vehicle manufacturer on the
vehicle placard or tire inflation pressure label. If your vehicle
has tires of a different size than the size indicated on the
vehicle placard or tire inflation pressure label, you should
determine the proper tire inflation pressure for those tires.
As an added safety feature, your vehicle has been equipped
with a Tire Pressure Monitoring System (TPMS) that illumi
-
nates a low tire pressure telltale when one or more of your
tires is significantly under-inflated. Accordingly, when the
low tire pressure telltale illuminates, you should stop and
check your tires as soon as possible, and inflate them to the
CAUTION!
Do not continue driving with one or more flat tires as
handling may be compromised. Stop the vehicle,
avoiding sharp braking and steering. If a tire puncture
occurs, repair immediately using the dedicated tire
repair kit and contact an authorized dealer as soon as
possible.

proper pressure. Driving on a significantly under-inflated
tire causes the tire to overheat and can lead to tire failure.
Under-inflation also reduces fuel efficiency and tire tread
life, and may affect the vehicle’s handling and stopping
ability.
Please note that the TPMS is not a substitute for proper tire
maintenance, and it is the driver’s responsibility to maintain
correct tire pressure, even if under-inflation has not reached
the level to trigger illumination of the TPMS low tire pres-
sure telltale.
Your vehicle has also been equipped with a TPMS malfunc -
tion indicator to indicate when the system is not operating
properly. The TPMS malfunction indicator is combined with
the low tire pressure telltale. When the system detects a
malfunction, the telltale will flash for approximately one
minute and then remain continuously illuminated. This
sequence will continue upon subsequent vehicle start-ups as
long as the malfunction exists. When the malfunction indi -
cator is illuminated, the system may not be able to detect or
signal low tire pressure as intended. TPMS malfunctions
may occur for a variety of reasons, including the installation
of replacement or alternate tires or wheels on the vehicle that
prevent the TPMS from functioning properly. Always check the TPMS malfunction telltale after replacing one or more
tires or wheels on your vehicle to ensure that the replace
-
ment or alternate tires and wheels allow the TPMS to
continue to function properly.
Vehicle Security Warning Light
This warning light will illuminate when the vehicle
security alarm system has detected an attempt to
break into the vehicle. CAUTION!
The TPMS has been optimized for the original
equipment tires and wheels. TPMS pressures and
warning have been established for the tire size equipped
on your vehicle. Undesirable system operation or sensor
damage may result when using replacement equipment
that is not of the same size, type, and/or style.
Aftermarket wheels can cause sensor damage. Using
aftermarket tire sealants may cause the Tire Pressure
Monitoring System (TPMS) sensor to become
inoperable. After using an aftermarket tire sealant it is
recommended that you take your vehicle to an
authorized dealer to have your sensor function checked.

104 SAFETY
27 psi (186 kPa), but the TPMS Warning Light will still be on.
In this situation, the TPMS Warning Light will turn off only
after the tires are inflated to the vehicle’s recommended cold
placard pressure value.NOTE:
• The TPMS is not intended to replace normal tire care and
maintenance or to provide warning of a tire failure or
condition.
• The TPMS should not be used as a tire pressure gauge while adjusting your tire pressure.
• Driving on a significantly under-inflated tire causes the tire to overheat and can lead to tire failure. Under-inflation
also reduces fuel efficiency and tire tread life, and may
affect the vehicle’s handling and stopping ability.
• The TPMS is not a substitute for proper tire maintenance, and it is the driver’s responsibility to maintain correct tire
pressure using an accurate tire pressure gauge, even if
under-inflation has not reached the level to trigger illumi -
nation of the TPMS Warning Light.
• Seasonal temperature changes will affect tire pressure, and the TPMS will monitor the actual tire pressure in the tire.
CAUTION!
• The TPMS has been optimized for the original equip -
ment tires and wheels. TPMS pressures and warning
have been established for the tire size equipped on
your vehicle. Undesirable system operation or sensor
damage may result when using replacement equipment
that is not of the same size, type, and/or style. After -
market wheels can cause sensor damage.
• Using aftermarket tire sealants may cause the Tire Pres -
sure Monitoring System (TPMS) sensor to become
inoperable. After using an aftermarket tire sealant it is
recommended that you take your vehicle to an autho -
rized dealership to have your sensor function checked.
• After inspecting or adjusting the tire pressure always reinstall the valve stem cap. This will prevent moisture
and dirt from entering the valve stem, which could
damage the TPMS sensor.

156 SAFETY
Periodic Safety Checks You Should Make Outside
The Vehicle
Tires
Examine tires for excessive tread wear and uneven wear
patterns. Check for stones, nails, glass, or other objects
lodged in the tread or sidewall. Inspect the tread for cuts and
cracks. Inspect sidewalls for cuts, cracks, and bulges. Check
the wheel bolts for tightness. Check the tires (including
spare) for proper cold inflation pressure.
Lights

Have someone observe the operation of brake lights and
exterior lights while you work the controls. Check turn signal
and high beam indicator lights on the instrument panel.

Door Latches
Check for proper closing, latching, and locking.
Fluid Leaks
Check area under the vehicle after overnight parking for
fuel, coolant, oil, or other fluid leaks. Also, if gasoline fumes
are detected or if fuel, or brake fluid leaks are suspected, the
cause should be located and corrected immediately.
• NEVER place any objects under the floor mat (e.g.,
towels, keys, etc.). These objects could change the posi -
tion of the floor mat and may cause interference with
the accelerator, brake, or clutch pedals.
• If the vehicle carpet has been removed and re-installed, always properly attach carpet to the floor and check the
floor mat fasteners are secure to the vehicle carpet.
Fully depress each pedal to check for interference with
the accelerator, brake, or clutch pedals then re-install
the floor mats.
• It is recommended to only use mild soap and water to clean your floor mats. After cleaning, always check
your floor mat has been properly installed and is
secured to your vehicle using the floor mat fasteners by
lightly pulling mat.

STARTING AND OPERATING 183
Gross Vehicle Weight Rating (GVWR)
The GVWR is the total allowable weight of your vehicle. This
includes driver, passengers, and cargo. The total load must
be limited so that you do not exceed the GVWR.
Gross Axle Weight Rating (GAWR)
The GAWR is the maximum capacity of the front and rear
axles. Distribute the load over the front and rear axles evenly.
Make sure that you do not exceed either front or rear GAWR.
Tire Size
The tire size on the Vehicle Certification Label represents the
actual tire size on your vehicle. Replacement tires must be
equal to the load capacity of this tire size.
Rim Size
This is the rim size that is appropriate for the tire size listed.
Inflation Pressure
This is the cold tire inflation pressure for your vehicle for all
loading conditions up to full GAWR.
Curb Weight
The curb weight of a vehicle is defined as the total weight of
the vehicle with all fluids, including vehicle fuel, at full
capacity conditions, and with no occupants or cargo loaded
into the vehicle. The front and rear curb weight values are
determined by weighing your vehicle on a commercial scale
before any occupants or cargo are added.
Overloading
The load carrying components (axle, springs, tires, wheels,
etc.) of your vehicle will provide satisfactory service as long
as you do not exceed the GVWR and the front and rear
GAWR.
The best way to figure out the total weight of your vehicle is
to weigh it when it is fully loaded and ready for operation.
Weigh it on a commercial scale to ensure that it is not over
the GVWR.
WARNING!
Because the front wheels steer the vehicle, it is important
that you do not exceed the maximum front or rear
GAWR. A dangerous driving condition can result if
either rating is exceeded. You could lose control of the
vehicle and have a collision.5
