Gear Shift Indicator (GSI) — If Equipped
The Gear Shift Indicator (GSI) system is
enabled on vehicles when automatic trans-
mission is in manual shift mode. The GSI
provides the driver with a visual indication
when the recommended gear shift point has
been reached. This indication notifies the
driver that changing gears will allow a reduc -
tion in fuel consumption. When the up shift
indicator is shown on the instrument cluster
display, the GSI is advising the driver to
engage a higher gear. When the down shift
indicator is shown on the display, the GSI is
advising the driver to engage a lower gear.
The GSI remains illuminated until the driver
changes gear, or the driving conditions
return to a situation where changing gears is
not required to improve fuel consumption.
Diesel Displays
When the appropriate conditions exist, the
following messages display in the instrument
cluster display:
Exhaust Filter Nearing Full Safely Drive at
Consistent Speeds to Clear
Exhaust Filter Full – Power Reduced See
Dealer
Exhaust System Service Required – See

Diesel Particulate Filter (DPF) Messages
This engine meets all required diesel engine
emissions standards. To achieve these emis -
sions standards, your vehicle is equipped
with a state-of-the-art engine and exhaust
system. These systems are seamlessly inte -
grated into your vehicle and managed by the
Powertrain Control Module (PCM). The PCM
manages engine combustion to allow the
exhaust system’s catalyst to trap and burn
Particulate Matter (PM) pollutants, with no
input or interaction on your part.
WARNING!
A hot exhaust system can start a fire if you
park over materials that can burn. Such
materials might be grass or leaves coming
into contact with your exhaust system. Do
not park or operate your vehicle in areas
where your exhaust system can contact
anything that can burn.
CAUTION!
Always drive at a speed appropriate to the
traffic conditions, the weather and traffic
regulations. The engine may be switched
off even if the warning light is on: repeated
interruptions of the regeneration process
could cause an early deterioration of
engine oil. For this reason it is always
advisable to wait for the symbol to go off
before turning off the engine, following the
instructions above. Do not complete the
DPF regeneration process when the vehicle
is stopped.

NOTE:
The stabilizer/sway bar may be torque locked
due to left and right suspension height
differences. This condition is due to driving
surface differences or vehicle loading. In
order for the stabilizer/sway bar to discon-
nect/reconnect, the right and left halves of
the bar must be aligned. This alignment may
require that the vehicle be driven onto level
ground or rocked from side to side.
To return to on-road mode, push the SWAY
BAR switch again.
STOP/START SYSTEM —
AUTOMATIC TRANSMISSION
(IF EQUIPPED)

The Stop/Start function is developed to
reduce fuel consumption. The system will
stop the engine automatically during a
vehicle stop if the required conditions are
met. Releasing the brake pedal or pressing
the accelerator pedal will automatically
re-start the engine.
Engine Stop/Start (ESS) vehicles have been
upgraded with a heavy duty starter,
enhanced battery, and other upgraded
engine parts, to handle the additional engine
starts.
NOTE:
It is recommended that the Stop/Start
System be disabled during off-road use. Secondary Battery
Your vehicle may be equipped with a
secondary battery used to power the Stop/
Start system and the 12 Volt vehicle elec
-
trical system. The secondary battery is
located behind the wheel well for the front
driver’s side wheel.
Battery Locations
WARNING!
If the stabilizer/sway bar will not return to
on-road mode, the “Sway Bar Indicator
Light” will flash in the instrument cluster
and vehicle stability may be reduced. Do
not attempt to drive the vehicle over
18 mph (29 km/h). Driving faster than
18 mph (29 km/h) with a disconnected
stabilizer/sway bar may contribute to the
loss of vehicle control, which could result
in serious injury.

(Continued)
Fluid Level Check
The fluid level is preset at the factory and
does not require adjustment under normal
operating conditions. Routine fluid level
checks are not required; therefore the trans-
mission has no dipstick. An authorized
dealer can check your transmission fluid
level using special service tools. If you notice
fluid leakage or transmission malfunction,
visit an authorized dealer immediately to
have the transmission fluid level checked.
Operating the vehicle with an improper fluid
level can cause severe transmission damage.
RAISING THE VEHICLE
In the case where it is necessary to raise the
vehicle, go to an authorized dealer or service
station.
TIRES
Tires — General Information
Tire Pressure
Proper tire inflation pressure is essential to
the safe and satisfactory operation of your
vehicle. Four primary areas are affected by
improper tire pressure:
Safety
Fuel Economy
Tread Wear
Ride Comfort and Vehicle Stability
Safety Both underinflation and overinflation affect
the stability of the vehicle and can produce
a feeling of sluggish response or over respon
-
siveness in the steering.
NOTE:
Unequal tire pressures from side to side
may cause erratic and unpredictable
steering response.
Unequal tire pressure from side to side
may cause the vehicle to drift left or right.
Fuel Economy

Underinflated tires will increase tire rolling
resistance resulting in higher fuel consumption.

CAUTION!
If a transmission fluid leak occurs, visit an
authorized dealer immediately. Severe
transmission damage may occur. An
authorized dealer has the proper tools to
adjust the fluid level accurately.
WARNING!
Improperly inflated tires are dangerous
and can cause collisions.
Underinflation increases tire flexing and
can result in overheating and tire failure.
Overinflation reduces a tire's ability to
cushion shock. Objects on the road and
chuckholes can cause damage that
result in tire failure.

Overinflated or underinflated tires can affect
vehicle handling and can fail suddenly,
resulting in loss of vehicle control.

Unequal tire pressures can cause
steering problems. You could lose
control of your vehicle.
Unequal tire pressures from one side of
the vehicle to the other can cause the
vehicle to drift to the right or left.

Always drive with each tire inflated to the
recommended cold tire inflation pressure.

FUEL CONSUMPTION AND
CO
2 EMISSIONS

The fuel consumption and CO2 emission
figures declared by the manufacturer are deter -
mined on the basis of the type-approval tests
laid down by the applicable standards in the
country where the vehicle is registered.

The type of route, traffic conditions, weather
conditions, driving style, general condition of
the vehicle, trim level/equipment/ accesso -
ries, use of the climate control system,
vehicle load, presence of roof racks and other
situations that adversely affect the aerody -
namics or wind resistance lead to different
fuel consumption values than those
measured. The fuel consumption will only become more
regular after driving the first 1,864 miles
(3,000 km).
To find the specific fuel consumption and
CO
