STARTING AND OPERATING145
(Continued)
ENGINE START/STOP Button Functions — With
Driver’s Foot OFF The Brake Pedal (In PARK Or
NEUTRAL Position)
The ENGINE START/STOP button operates similar
to an ignition switch. It has three positions: OFF,
ACC, and ON/RUN. To change the ignition modes
without starting the vehicle and use the
accessories, follow these directions:

1. Start with the ignition in the OFF position.

2. Push the ENGINE START/STOP button once to
place the ignition to the ACC position.
3. Push the ENGINE START/STOP button a second time to place the ignition to the ON/
RUN position.
4. Push the ENGINE START/STOP button a third time to return the ignition to the OFF position.
COLD WEATHER OPERATION (BELOW
–22°F O
R −30°C)
To ensure reliable starting at these temperatures,
use of an externally powered electric engine block
heater (available from an authorized dealer) is
recommended.
AFTER STARTING
The idle speed is controlled automatically, and it
will decrease as the engine warms up.
STARTING FLUIDS — DIESEL ENGINE
O
NLY
The engine is equipped with a glow plug preheating
system. If the instructions in this manual are
followed, the engine should start in all conditions
and no type of starting fluid should be used.
WARNING!
Do not leave children or animals inside parked
vehicles in hot weather. Interior heat build up
may cause serious injury or death.
When leaving the vehicle, always make sure
the wireless ignition node is in the OFF posi -
tion, remove the key fob from the vehicle and
lock the vehicle.
Never leave children alone in a vehicle, or with
access to an unlocked vehicle. Allowing
children to be in a vehicle unattended is
dangerous for a number of reasons. A child or
others could be seriously or fatally injured.
Children should be warned not to touch the
parking brake, brake pedal or the gear
selector.
Do not leave the key fob in or near the vehicle,
or in a location accessible to children, and do
not leave the ignition of a vehicle equipped
with Keyless Enter ‘n Go™ in the ACC or ON/
RUN position. A child could operate power
windows, other controls, or move the vehicle.

STARTING AND OPERATING149
Do Not Operate The Engine With Low Oil
Pressure
If the Low Oil Pressure Warning Light turns on while
driving, stop the vehicle and shut down the engine
as soon as possible. After the vehicle is safely
stopped, restart the engine and monitor the lamp.
If the lamp is still illuminated, shut the engine off,
contact an authorized dealer, and do not operate
the vehicle until the cause is corrected. If the lamp
is no longer illuminated, the engine can be
operated, but should be taken to an authorized
dealer as soon as possible for further inspection.
NOTE:Do not operate the vehicle until the cause is
corrected. This light does not show how much oil is
in the engine. The engine oil level must be checked
under the hood.
Do Not Operate The Engine With Failed
Parts
All engine failures give some warning before the
parts fail. Some important observations are:
Engine misfiring or vibrating severely
Sudden loss of power
Unusual engine noises
Fuel, oil or coolant leaks
Sudden change, outside the normal operating
range, in the engine operating temperature
Excessive smoke
Oil pressure drop
ENGINE BLOCK HEATER — IF EQUIPPED

Engine Block Heater Cord Location
The engine block heater warms engine coolant and
permits quicker starts in cold weather. Connect the
heater cord to a ground-fault interrupter protected
110–115 Volt AC electrical outlet with a grounded,
three-wire extension cord.
For diesel engines, its use is recommended for
environments that routinely fall below -10°F
(-23°C). It should be used when the vehicle has not
been running for long periods of time and should
be plugged in two hours prior to start. Its use is
required for cold starts with temperatures under
-20°F (-28°C).
To ensure reliable starting at these temperatures,
use of an externally powered electric engine block
heater (available from an authorized dealer) is
recommended.
The engine block heater cord is routed under the
hood on the passenger side of the vehicle next to
the engine coolant reservoir.
CAUTION!
If oil pressure falls to less than normal readings,
shut the engine off immediately. Failure to do so
could result in immediate and severe engine
damage.WARNING!
Remember to disconnect the engine block
heater cord before driving. Damage to the
110-115 Volt electrical cord could cause
electrocution.
