GETTING TO KNOW YOUR INSTRUMENT PANEL49
Values Displayed
Range
This indicates the distance which may be
traveled with the fuel remaining in the tank,
assuming that driving conditions will not
change. The message “----” will appear on the
display in the following cases:
Distance less than 30 miles (or 50 km).
The vehicle is parked for a long time with the
engine running.
NOTE:
The range depends on several factors: driving
style, type of route (freeway, residential, moun -
tain 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
precautionary 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 applicable.
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 by
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.
Brake Warning Light
This warning light monitors various
brake functions, including brake fluid
level and parking brake application. If
the brake light turns on it may
indicate that the parking brake is applied, that
the brake fluid level is low, or that there is a
problem with the Anti-Lock Brake System
reservoir.

21_VM_OM_EN_USC_t.book Page 49

50GETTING TO KNOW YOUR INSTRUMENT PANEL
If the light remains on when the parking brake
has been disengaged, and the fluid level is at
the full mark on the master cylinder reservoir, it
indicates a possible brake hydraulic system
malfunction or that a problem with the Brake
Booster has been detected by the Anti-Lock
Brake System (ABS) / Electronic Stability
Control (ESC) system. In this case, the light will
remain on until the condition has been
corrected. If the problem is related to the brake
booster, the ABS pump will run when applying
the brake, and a brake pedal pulsation may be
felt during each stop.
The dual brake system provides a reserve
braking capacity in the event of a failure to a
portion of the hydraulic system. A leak in either
half of the dual brake system is indicated by the
Brake Warning Light, which will turn on when
the brake fluid level in the master cylinder has
dropped below a specified level.
The light will remain on until the cause is
corrected. NOTE:
The light may flash momentarily during sharp
cornering maneuvers, which change fluid level
conditions. The vehicle should have service
performed, and the brake fluid level checked.
If brake failure is indicated, immediate repair is
necessary.
Vehicles equipped with the Anti-Lock Brake
System (ABS) are also equipped with Electronic
Brake Force Distribution (EBD). In the event of
an EBD failure, the Brake Warning Light will turn
on along with the ABS Light. Immediate repair to
the ABS system is required.
Operation of the Brake Warning Light can be
checked by turning the ignition switch from the
OFF position to the ON/RUN position. The light
should illuminate for approximately two seconds. The light should then turn off unless
the parking brake is applied or a brake fault is
detected. If the light does not illuminate, have
the light inspected by an authorized dealer.
The light also will turn on when the parking
brake is applied with the ignition switch in the
ON/RUN position.
NOTE:
This light shows only that the parking brake is
applied. It does not show the degree of brake
application.
Battery Charge Warning Light
This warning light will illuminate when
the battery is not charging properly. If
it stays on while the engine is running,
there may be a malfunction with the
charging system. Contact an authorized dealer
as soon as possible. This indicates a possible
problem with the electrical system or a related
component.
WARNING!
Driving a vehicle with the red brake light on is
dangerous. Part of the brake system may
have failed. It will take longer to stop the
vehicle. You could have a collision. Have the
vehicle checked immediately.

21_VM_OM_EN_USC_t.book Page 50

52GETTING TO KNOW YOUR INSTRUMENT PANEL
Seat Belt Reminder Warning Light
When the ignition is first placed in the
ON/RUN or MAR/ON/RUN position, if
the driver’s seat belt is unbuckled, a
chime will sound and the light will turn
on. When driving, if the driver or front passenger
seat belt remains unbuckled, the Seat Belt
Reminder Light will flash or remain on
continuously and a chime will sound
Ú page 153.
Transmission Fault Warning Light
This light will illuminate (together with
a message in the instrument cluster
display and a buzzer) to indicate a
transmission fault. Contact an
authorized dealer if the message remains after
restarting the engine.
Engine Oil Level Warning Light
This warning light appears on the
panel when the engine oil level falls
below the minimum recommended
value. Restore the correct engine oil
level or contact your authorized dealer for
service.
Yellow Warning Lights
Anti-Lock Brake System (ABS) Warning Light
This light monitors the ABS. The light
will turn on when the ignition is placed
in the ON/RUN or MAR/ON/RUN
position and may stay on for as long
as four seconds.
If the ABS light remains on or turns on while
driving, then the Anti-Lock portion of the brake
system is not functioning and service is
required. However, the conventional brake system will continue to operate normally if the
brake warning light is not on.
If the ABS light is on, the brake system should
be serviced as soon as possible to restore the
benefits of Anti-Lock Brakes. If the ABS light
does not turn on when the ignition is placed in
the ON/RUN or MAR/ON/RUN position, have
the light inspected by an authorized dealer.
Low Fuel Warning Light
When 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.
WARNING!
If you continue operating the vehicle when
the Transmission Temperature Warning Light
is illuminated you could cause the fluid to boil
over, come in contact with hot engine or
exhaust components and cause a fire.
CAUTION!
Continuous driving with the Transmission
Temperature Warning Light illuminated will
eventually cause severe transmission
damage or transmission failure.

76STARTING AND OPERATING
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. Figure out the weight on the front and rear of
the vehicle separately. It is important that you
distribute the load evenly over the front and rear
axles.
Overloading can cause potential safety hazards
and shorten useful service life. Heavier axles or
suspension components do not necessarily
increase the vehicle's GVWR.
Loading
To load your vehicle properly, first figure out its
empty weight, axle-by-axle and side-by-side.
Store heavier items down low and be sure you
distribute their weight as evenly as possible.
Stow all loose items securely before driving. If
weighing the loaded vehicle shows that you
have exceeded either GAWR, but the total load
is within the specified GVWR, you must
redistribute the weight. Improper weight
distribution can have an adverse effect on the
way your vehicle steers and handles and the
way the brakes operate.
NOTE:
Refer to the “Vehicle Certification Label” affixed
to the B-Pillar or the rear of the driver's door for
your vehicle's GVWR and GAWRs.
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.

STARTING AND OPERATING85
(Continued)
Shallow Standing Water
Although your vehicle is capable of driving
through shallow standing water, consider the
following Cautions and Warnings before doing
so.
WARNING!
Driving through standing water limits your
vehicle’s traction capabilities. Do not
exceed 5 mph (8 km/h) when driving
through standing water.
Driving through standing water limits your
vehicle’s braking capabilities, which
increases stopping distances. Therefore,
after driving through standing water, drive
slowly and lightly press on the brake pedal
several times to dry the brakes.
Failure to follow these warnings may result
in injuries that are serious or fatal to you,
your passengers, and others around you.
CAUTION!
Always check the depth of the standing
water before driving through it. Never drive
through standing water that is deeper than
the bottom of the tire rims mounted on the
vehicle.
Determine the condition of the road or the
path that is under water and if there are any
obstacles in the way before driving through
the standing water.
Do not exceed 5 mph (8 km/h) when
driving through standing water. This will
minimize wave effects.
Driving through standing water may cause
damage to your vehicle’s drivetrain compo -
nents. Always inspect your vehicle’s fluids
(i.e., engine oil, transmission, axle, etc.) for
signs of contamination (i.e., fluid that is
milky or foamy in appearance) after driving
through standing water. Do not continue to
operate the vehicle if any fluid appears
contaminated, as this may result in further
damage. Such damage is not covered by
the New Vehicle Limited Warranty.
Getting water inside your vehicle’s engine
can cause it to lock up and stall out, and
cause serious internal damage to the
engine. Such damage is not covered by the
New Vehicle Limited Warranty.
CAUTION! (Continued)

SAFETY187
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 lug nut/bold torque 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 position of the floor mat
and may cause interference with the accel -
erator, 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 inter -
ference 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.
