Swivel Seat — If Equipped
The swivel seat lever is located at the lower front
inboard side of the seat. The seat may be turned
through 180° toward the seat on the opposite side
and approximately 35° toward the door. The seat
may be locked in the driving position or at the
180° position. To swivel the seat, pull the swivel
seat inboard lever outward, turn the seat to the
desired position and release the lever.

Swivel Seat Lever

If the vehicle is equipped with interlocking swivel
seats, the seats must be locked in the facing
forward position while driving. If the seats are not
in the correct position, a warning will appear in the
instrument cluster display. If the driver or the passenger seats are not locked
in the facing forward position before the first
vehicle movement, shifting out of park is not
allowed until the seats are both locked in the
facing forward position. When the seats are not in
the right position and the first vehicle movement
after ignition START is attempted, a chime and a
message will appear in the instrument cluster
display. Rotate and lock the swivel seats in the
correct position before trying again.
If the driver or the passenger seats are not locked
in the facing forward position during movement
of the vehicle, a message will appear in the
instrument cluster display and an intermittent
chime will sound until key-off or until the swivel
seats are locked in the facing forward position.
Stop and move the swivel seats in the correct
position before proceeding.
If a fault is present in the system and it is not
possible to check the correct position of the swivel
seats, a message and the generic warning light
appears in the instrument cluster display to inform
about the failure. In these conditions, check the
status of the swivel seats and do not drive the
vehicle until the swivel seats are locked in the
facing forward position.
HEATED SEATS — IF EQUIPPED
On some models, the front driver and
passenger seats may be equipped with
heaters in both the seat cushions and
seatbacks. The controls for the front
heated seats are located on the lower outboard
side of the seat.

Heated Seat Switch

Push the switch once to turn on the heated seats.
Push the switch a second time to shut the heating
elements off.

23_VF_OM_EN_USC_t.book Page 26

GETTING TO KNOW YOUR VEHICLE27
NOTE:Once a heat setting is selected, heat will be felt
within two to five minutes.
FOLD DOWN TRAY — IF EQUIPPED
If your vehicle is equipped with a bench seat, the
seat is equipped with a fold-down tray that can be
used as a document support surface. To use the
fold-down tray, grab the pull tab and lower the tray.
Lowering The Fold-Down Tray

The fold-down tray is equipped with two cup holders
and a support surface with a paper holder clip.

Closing The Fold-Down Tray

ADJUSTABLE ARMRESTS — IF EQUIPPED
The seat adjustable armrest can be raised and
adjusted for height. Underneath the front of the
armrest is the adjuster wheel which will adjust the
height of the armrest up or down.
Adjuster Wheel Location

WARNING!
Persons who are unable to feel pain to the
skin because of advanced age, chronic illness,
diabetes, spinal cord injury, medication,
alcohol use, exhaustion or other physical
condition must exercise care when using the
seat heater. It may cause burns even at low
temperatures, especially if used for long
periods of time.
Do not place anything on the seat or seatback
that insulates against heat, such as a blanket
or cushion. This may cause the seat heater to
overheat. Sitting in a seat that has been over -
heated could cause serious burns due to the
increased surface temperature of the seat.

Climate Control OFF Button
Press and release this button to turn the
Climate Control ON/OFF.
ADDITIONAL REAR CLIMATE CONTROL —
I
F EQUIPPED
These switches, mounted on the instrument panel
to the left of the steering column, activate the
additional rear heating/air conditioning system.
NOTE:These switches must be enabled for operation by
the Upfitter.

Additional Rear Climate Controls Switches

Rear Blower Control

Push this button to turn on the rear climate
controls. An indicator light will turn on when
the rear climate control is on.

OPERATING TIPS
Refer to the chart at the end of this section for
suggested control settings for various weather
conditions.
Summer Operation
The engine cooling system must be protected
with a high-quality antifreeze coolant to provide
proper corrosion protection and to protect against
engine overheating. OAT coolant (conforming to
MS.90032) is recommended.
Winter Operation
To ensure the best possible heater and defroster
performance, make sure the engine cooling
system is functioning properly and the proper
amount, type, and concentration of coolant is
used. Use of the Air Recirculation mode during
Winter months is not recommended, because it
may cause window fogging.
Vacation Storage
For information on maintaining the Climate Control
system when the vehicle is being stored for an
extended period of time, see Ú page 265.
Window Fogging

Vehicle windows tend to fog on the inside in mild, rainy,
and/or humid weather. To clear the windows, select
Defrost or Mix mode and increase the front blower
speed. Do not use the Recirculation mode without A/C
for long periods, as fogging may occur.

Outside Air Intake
Make sure the air intake, located directly in front of
the windshield, is free of obstructions, such as
leaves. Leaves collected in the air intake may
reduce airflow, and if they enter the air distribution
box, they could plug the water drains. In Winter
months, make sure the air intake is clear of ice,
slush, and snow.
Cabin Air Filter
The Climate Control system filters out dust and
pollen from the air. Contact an authorized dealer to
service your cabin air filter, and to have it replaced
when needed.

STARTING AND OPERATING77
3. If the engine fails to start within 10 seconds, place the ignition in the OFF position, wait
10 to 15 seconds to allow the starter to cool,
then repeat the “Extended Park Starting”
procedure.
4. If the engine fails to start after eight attempts, allow the starter to cool for at least
10 minutes, then repeat the procedure.
IF ENGINE FAILS TO START

If the engine fails to start after you have followed the
“Normal Starting” procedure, and the vehicle has not
experienced an extended park condition as previously
defined, it may be flooded. Push the accelerator pedal
all the way to the floor and hold it there. Crank the
engine for no more than 10 seconds. This should clear
any excess fuel in case the engine is flooded. Leave the

continuously for more than 10 seconds at a
time. Wait 10 to 15 seconds before trying again.
WARNING!
Never pour fuel or other flammable liquid
into the throttle body air inlet opening in an
attempt to start the vehicle. This could result
in flash fire causing serious personal injury.
Do not attempt to push or tow your vehicle to
get it started. Vehicles equipped with an auto -
matic transmission cannot be started this
way. Unburned fuel could enter the catalytic
converter and once the engine has started,
ignite and damage the converter and vehicle.
If the vehicle has a discharged battery,
booster cables may be used to obtain a start
from a booster battery or the battery in
another vehicle. This type of start can be
dangerous if done improperly Ú page 214.
CAUTION!
To prevent damage to the starter, do not
continuously crank the engine for more than
10 seconds at a time. Wait 10 to 15 seconds
before trying again.
WARNING!

Remember to disconnect the engine block heater
cord before driving. Damage to the 110-115 Volt
electrical cord could cause electrocution.
