GETTING TO KNOW YOUR VEHICLE21
STEERING WHEEL
Telescoping Steering Column
This feature allows you to lengthen or shorten
the steering column. The telescoping control
handle is located below the steering wheel at
the end of the steering column.
Telescoping Control Handle
To unlock the steering column, pull the control
handle up. To lengthen or shorten the steering
column, pull the steering wheel outward or push
it inward as desired. To lock the steering column
in position, push the control handle down until
fully engaged.
MIRRORS
Inside Day/Night Mirror — If Equipped
A two-point pivot system allows for horizontal
and vertical adjustment of the mirror. Adjust the
mirror to center on the view through the rear
window.
Headlight glare can be reduced by moving the
small control under the mirror to the night posi -
tion (toward the rear of the vehicle). The mirror
should be adjusted while set in the day position
(toward the windshield). Adjusting Rearview Mirror
Outside Mirrors
To receive maximum benefit, adjust the outside
mirror(s) to center on the adjacent lane of traffic
with a slight overlap of the view obtained on the
inside mirror.
WARNING!
Do not adjust the steering column while
driving. Adjusting the steering column while
driving or driving with the steering column
unlocked, could cause the driver to lose
control of the vehicle. Failure to follow this
warning may result in serious injury or death.
WARNING!
Vehicles and other objects seen in an outside
convex mirror will look smaller and farther
away than they really are. Relying too much
on side convex mirrors could cause you to
collide with another vehicle or other object.
Use your inside mirror when judging the size
or distance of a vehicle seen in a side convex
mirror.

GETTING TO KNOW YOUR INSTRUMENT PANEL51
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
replacement or alternate tires and wheels allow
the TPMS to continue to function properly.Electronic Stability Control (ESC) Warning Light
The “ESC Indicator Light” in the instru-
ment cluster will come on when the
ignition is placed in the ON/RUN or
MAR (ACC/ON/RUN) position, and
when ESC is activated. It should turn off with the
engine running. If the “ESC Indicator Light”
comes on continuously with the engine running,
a malfunction has been detected in the ESC
system. If this light remains on after several
ignition cycles, and the vehicle has been driven
several miles (kilometers) at speeds greater
than 30 mph (48 km/h), see an authorized
dealer as soon as possible to have the problem
diagnosed and corrected.
The “ESC OFF Indicator Light” and the “ESC
Indicator Light” come on momentarily each
time the ignition is placed in the ON/RUN or
MAR (ACC/ON/RUN) position.
Each time the ignition is turned to ON/RUN or
MAR (ACC/ON/RUN), the ESC system will be
on, even if it was turned off previously.
The ESC system will make buzzing or clicking
sounds when it is active. This is normal; the
sounds will stop when ESC becomes inactive.
This light will come on when the vehicle is in
an ESC event.
Electronic Stability Control (ESC) OFF Warning
Light
This light indicates the Electronic
Stability Control (ESC) is off.
Each time the ignition is turned to ON/RUN or
MAR/ON/RUN, the ESC system will be on, even
if it was turned off previously.
Engine Check/Malfunction Indicator Warning Light
(MIL)
The Engine Check/Malfunction Indi -
cator Light (MIL) is a part of an
Onboard Diagnostic System called
OBD II that monitors engine and auto -
matic transmission control systems. This
warning light will illuminate when the ignition is
in the ON/RUN position before engine start. If
the bulb does not come on when turning the
ignition switch from OFF to ON/RUN, have the
condition checked promptly.
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.

ESC Operating Modes
The “ESC OFF” switch is located in the
center switch bank, next to the hazard
flasher switch.
ESC On
This mode is the normal operating mode for ESC
equipped vehicles. Whenever the vehicle is
started, the ESC system will be in this mode.
This mode should be used for most driving situ -
ations. ESC should only be turned off for
specific reasons as noted below.
ESC Partial Off
This mode is entered by momentarily pushing
the “ESC OFF” switch.

When in the “Partial Off” mode, the TCS portion
of ESC, except for the “limited slip” feature
described in the TCS section, has been disabled
and the “ESC OFF Indicator Light” will be illumi-
nated. When in the “Partial Off” mode, ESC will
operate without engine torque management.
This mode is intended to be used if the vehicle is
in deep snow, sand or gravel conditions and
more wheel spin than ESC would normally allow
is required to gain traction. To turn ESC on again,
momentarily push the “ESC OFF” switch. This will
restore the normal “ESC On” mode of operation.
WARNING!
Electronic Stability Control (ESC) cannot
prevent the natural laws of physics from
acting on the vehicle, nor can it increase
the traction afforded by prevailing road
conditions. ESC cannot prevent acci -
dents, including those resulting from
excessive speed in turns, driving on very
slippery surfaces, or hydroplaning. ESC
also cannot prevent accidents resulting
from loss of vehicle control due to inap -
propriate driver input for the conditions.
Only a safe, attentive, and skillful driver
can prevent accidents. The capabilities of
an ESC equipped vehicle must never be
exploited in a reckless or dangerous
manner which could jeopardize the user’s
safety or the safety of others.Vehicle modifications, or failure to properly
maintain your vehicle, may change the
handling characteristics of your vehicle,
and may negatively affect the performance
of the ESC system. Changes to the steering
system, suspension, braking system, tire
type and size or wheel size may adversely
affect ESC performance. Improperly
inflated and unevenly worn tires may also
degrade ESC performance. Any vehicle
modification or poor vehicle maintenance
that reduces the effectiveness of the ESC
system can increase the risk of loss of
vehicle control, vehicle rollover, personal
injury and death.
WARNING!
(Continued)
20_VF_OM_EN_US_t.book Page 58

62SAFETY
(Continued)
The TPMS will warn the driver of a low tire pres -
sure if the tire pressure falls below the low-pres -
sure warning limit for any reason, including low
temperature effects and natural pressure loss
through the tire.
The TPMS will continue to warn the driver of low
tire pressure as long as the condition exists,
and will not turn off until the tire pressure is at
or above the recommended cold placard pres -
sure. Once the low tire pressure warning (TPMS
Warning Light) illuminates, you must increase
the tire pressure to the recommended cold
placard pressure in order for the TPMS Warning
Light to turn off. The system will automatically
update and the TPMS Warning Light will turn off
once the system receives the updated tire pres -
sures. The vehicle may need to be driven for up
to 20 minutes above 15 mph (24 km/h) in
order for the TPMS to receive this information.
NOTE:
When filling warm tires, the tire pressure may
need to be increased up to an additional 4 psi
(28 kPa) above the recommended cold placard
pressure in order to turn the TPMS Warning
Light off.
For example, your vehicle may have a recom
-
mended cold (parked for more than three
hours) placard pressure of 30 psi (207 kPa).
If the ambient temperature is 68°F (20°C)
and the measured tire pressure is 27 psi
(186 kPa), a temperature drop to 20°F
(-7°C) will decrease the tire pressure to
approximately 23 psi (158 kPa). This tire
pressure is sufficiently low enough to turn on
the TPMS Warning Light. Driving the vehicle
may cause the tire pressure to rise to approx -
imately 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 recom -
mended 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 pres
-
sure 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.
CAUTION!
The TPMS has been optimized for the orig -
inal equipment tires and wheels. TPMS
pressures and warning have been estab -
lished 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 dealership to have your
sensor function checked.
After inspecting or adjusting the tire pres -
sure always reinstall the valve stem cap.
This will prevent moisture and dirt from
entering the valve stem, which could
damage the TPMS sensor.
CAUTION!

20_VF_OM_EN_US_t.book Page 62

64SAFETY
NOTE:
Your vehicle is equipped with a regular size
spare wheel.
1. The spare tire does not have a TPM sensor.
Therefore, the TPMS will not monitor the
pressure in the spare tire.
2. If a spare tire not equipped with the Tire Pressure Monitoring sensor is used, the
TPMS Warning Light will turn on, flashing for
75 seconds and then remaining solid for
each subsequent ignition key cycle.
3. Once you repair or replace the original road tire and reinstall it on the vehicle in place of
the spare tire, the TPMS will update auto -
matically and the Tire Pressure Monitoring
Light will extinguish once the updated tire
pressures have been received. The vehicle
may need to be driven for up to 20 minutes
above 15 mph (24 km/h) to receive this
information.
NOTE:
For correct Tire Pressure Monitoring behavior,
please wait for about 20 minutes in key-off
during each tire substitution.General Information

OCCUPANT RESTRAINT SYSTEMS
Some of the most important safety features in
your vehicle are the restraint systems:
Occupant Restraint Systems Features
Seat Belt Systems
Supplemental Restraint Systems (SRS) Air
Bags
Child Restraints

20_VF_OM_EN_US_t.book Page 64

76SAFETY
Because air bag sensors measure vehicle
deceleration over time, vehicle speed and
damage by themselves are not good indicators
of whether or not an air bag should have
deployed.
Seat belts are necessary for your protection in
all collisions, and also are needed to help keep
you in position, away from an inflating air bag.
When the ORC detects a collision requiring the
front air bags, it signals the inflator units. A large
quantity of non-toxic gas is generated to inflate
the front air bags.
The steering wheel hub trim cover and the
upper passenger side of the instrument panel
separate and fold out of the way as the air bags
inflate to their full size. The front air bags fully
inflate in less time than it takes to blink your
eyes. The front air bags then quickly deflate
while helping to restrain the driver and front
passenger.Supplemental Side Air Bags
Supplemental Seat-Mounted Side Air Bags
(SABs)
This vehicle is equipped with Supplemental
Seat-Mounted Side Air Bags (SABs).
Supplemental Seat-Mounted Side Air Bags
(SABs) are located in the outboard side of the
front seats. The SABs are marked with “SRS
AIRBAG” or “AIRBAG” on a label or on the seat
trim on the outboard side of the seats.
The SABs may help to reduce the risk of occu -
pant injury during certain side impacts, in addi -
tion to the injury reduction potential provided by
the seat belts and body structure.

Front Supplemental Seat-Mounted Side Air Bag Label
When the SAB deploys, it opens the seam on
the outboard side of the seatback’s trim cover.
The inflating SAB deploys through the seat
seam into the space between the occupant and
the door. The SAB moves at a very high speed
and with such a high force that it could injure
occupants if they are not seated properly, or if
items are positioned in the area where the SAB
inflates. Children are at an even greater risk of
injury from a deploying air bag.
WARNING!
Do not use accessory seat covers or place
objects between you and the Side Air Bags;
the performance could be adversely affected
and/or objects could be pushed into you,
causing serious injury.

20_VF_OM_EN_US_t.book Page 76

112STARTING AND OPERATING
VEHICLE LOADING
As required by National Highway Traffic Safety
Administration regulations, your vehicle has a
certification label affixed to the driver's side
door or B-Pillar.
If seats are removed for carrying cargo, do not
exceed the specified GVWR and GAWR.
Vehicle Certification Label
Your vehicle has a Vehicle Certification Label
affixed to the drivers side B-Pillar or the rear of
the driver’s door.
The label contains the following information:
Name of manufacturer
Month and year of manufacture
Gross Vehicle Weight Rating (GVWR)
Gross Axle Weight Rating (GAWR) front
Gross Axle Weight Rating (GAWR) rear
Vehicle Identification Number (VIN)
Type of vehicle
Month, Day, and Hour of manufacture (MDH)
The bar code allows a computer scanner to read
the VIN.
Gross Vehicle Weight Rating (GVWR)
The Gross Vehicle Weight Rating (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 Gross Axle Weight Rating (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 Gross
Axle Weight Rating (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 condi -
tions, 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 Gross Vehicle Weight Rating (GVWR)
and the front and rear Gross Axle Weight Rating
(GAWR).
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.

20_VF_OM_EN_US_t.book Page 112

114STARTING AND OPERATING
Tongue Weight (TW)
The Tongue Weight (TW) is the downward force
exerted on the hitch ball by the trailer. You must
consider this as part of the load on your vehicle.
Trailer Frontal Area
The frontal area is the maximum height multi -
plied by the maximum width of the front of a
trailer.
Trailer Sway Control
The Trailer Sway Control (TSC) can be a
mechanical telescoping link that can be
installed between the hitch receiver and the
trailer tongue that typically provides adjustable
friction associated with the telescoping motion
to dampen any unwanted trailer swaying
motions while traveling. If equipped, the electronic TSC recognizes a
swaying trailer and automatically applies indi
-
vidual wheel brakes and/or reduces engine
power to attempt to eliminate the trailer sway.
Weight-Carrying Hitch
A weight-carrying hitch supports the trailer
tongue weight, just as if it were luggage located
at a hitch ball or some other connecting point of
the vehicle. These kinds of hitches are the most
popular on the market today and they are
commonly used to tow small and medium sized
trailers.
Weight-Distributing Hitch
A weight-distributing system works by applying
leverage through spring (load) bars. They are
typically used for heavier loads to distribute
trailer tongue weight to the tow vehicle's front
axle and the trailer axle(s). When used in accor -
dance with the manufacturer's directions, it
provides for a more level ride, offering more
consistent steering and brake control thereby
enhancing towing safety. The addition of a fric -
tion/hydraulic sway control also dampens sway
caused by traffic and crosswinds and contrib -
utes positively to tow vehicle and trailer
stability. Trailer sway control and a weight distributing (load equalizing) hitch are recom
-
mended for heavier Tongue Weights (TW) and
may be required depending on vehicle and
trailer configuration/loading to comply with
Gross Axle Weight Rating (GAWR) requirements.
Trailer Hitch Classification
The following chart provides the industry stan -
dard for the maximum trailer weight a given
trailer hitch class can tow and should be used to
assist you in selecting the correct trailer hitch
for your intended towing condition.
WARNING!
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.
WARNING!
An improperly adjusted Weight Distributing
Hitch system may reduce handling,
stability, braking performance, and could
result in a collision.
Weight Distributing Systems may not be
compatible with Surge Brake Couplers.
Consult with your hitch and trailer manufac -
turer or a reputable Recreational Vehicle
dealer for additional information.

20_VF_OM_EN_US_t.book Page 114

178SERVICING AND MAINTENANCE
Radial Ply Tires
Tire Repair
If your tire becomes damaged, it may be
repaired if it meets the following criteria:
The tire has not been driven on when flat.
The damage is only on the tread section of
your tire (sidewall damage is not repairable).
The puncture is no greater than a ¼ of an
inch (6 mm).
Consult an authorized tire dealer for tire repairs
and additional information. Damaged Run Flat tires, or Run Flat tires that
have experienced a loss of pressure should be
replaced immediately with another Run Flat tire
of identical size and service description (Load
Index and Speed Symbol). Replace the tire pres
-
sure sensor as well as it is not designed to be
reused.
Run Flat Tires — If Equipped
Run Flat tires allow you the capability to drive
50 miles (80 km) at 50 mph (80 km/h) after a
rapid loss of inflation pressure. This rapid loss
of inflation is referred to as the Run Flat mode.
A Run Flat mode occurs when the tire inflation
pressure is of/or below 14 psi (96 kPa). Once a
Run Flat tire reaches the run flat mode it has
limited driving capabilities and needs to be
replaced immediately. A Run Flat tire is not
repairable. When a run flat tire is changed after
driving with underinflated tire condition, please
replace the TPM sensor as it is not designed to
be reused when driven under run flat mode 14
psi (96 kPa) condition.
NOTE:
TPM Sensor must be replaced after driving the
vehicle on a flat tire condition. It is not recommended driving a vehicle loaded
at full capacity or to tow a trailer while a tire is in
the run flat mode.
See the tire pressure monitoring section for
more information.
Tire Spinning

When stuck in mud, sand, snow, or ice condi
-
tions, do not spin your vehicle's wheels
above 30 mph (48 km/h) or for longer than
30 seconds continuously without stopping.

Refer to “Freeing A Stuck Vehicle” in “In Case Of
Emergency” for further information.
WARNING!
Combining radial ply tires with other types of
tires on your vehicle will cause your vehicle to
handle poorly. The instability could cause a
collision. Always use radial ply tires in sets of
four. Never combine them with other types of
tires.
WARNING!
Fast spinning tires can be dangerous.
Forces generated by excessive wheel
speeds may cause tire damage or failure. A
tire could explode and injure someone. Do
not spin your vehicle's wheels faster than
30 mph (48 km/h) for more than 30
seconds continuously when you are stuck,
and do not let anyone near a spinning
wheel, no matter what the speed.
