Extending Engine Run Time
To extend the engine run time by
10 minutes, repeat Steps 1and 2
while the engine is still running. An
extension can be requested
30 seconds after starting. The
engine run time can only be
extended if it is the first remote start
since the vehicle has been driven.
Remote start can be extended
one time.
If the remote start procedure is used
again before the first 10-minute time
frame has ended, the first
10 minutes will immediately expire
and the second 10-minute time
frame will start.
For example, if
Qand then/are
pressed again after the vehicle has
been running for five minutes,
10 minutes are added, allowing the
engine to run for a total of
15 minutes.
A maximum of two remote starts or
remote start with an extension are
allowed between ignition cycles. After the vehicle's engine has been
started two times using the remote
start button or a start with an
extension, the ignition must be
turned on and then back off before
the remote start procedure can be
used again.
Canceling a Remote Start
To manually shut off a remote start:
.
Press and hold
/until the
lamps turn off.
. Turn on the hazard warning
flashers.
. Turn the ignition switch on and
then off.
Conditions in Which the
Remote Start Will Not Work
The vehicle cannot be started using
the remote start feature if the key is
in the ignition, the hood is open,
or there is an emission control
system malfunction.
The engine turns off during a remote
start if the coolant temperature gets
too high or if the oil pressure
gets low.
Door Locks
{Warning
Unlocked doors can be
dangerous.
. Passengers, especially
children, can easily open
the doors and fall out of a
moving vehicle. When a
door is locked, the handle
will not open it. The chance
of being thrown out of the
vehicle in a crash is
increased if the doors are
not locked. So, all
passengers should wear
safety belts properly and the
doors should be locked
whenever the vehicle is
driven.
. Young children who get into
unlocked vehicles may be
unable to get out. A child
can be overcome by
extreme heat and can suffer
permanent injuries or even

112 Instruments and Controls
Here are some situations that can
occur with the fuel gauge. None of
these indicate a problem with the
fuel gauge.
.At the gas station, the fuel pump
shuts off before the gauge
reads full.
. It takes a little more or less fuel
to fill up than the fuel gauge
indicated. For example, the
gauge may have indicated the
tank was half full, but it actually
took a little more or less than
half the tank's capacity to fill
the tank.
. The gauge moves a little while
turning a corner or speeding up.
. The gauge goes back to empty
when the ignition is turned off.Engine Coolant
Temperature Gauge
Metric
English
This gauge shows the engine
coolant temperature. Under normal
driving conditions the gauge will
read 100°C (210°F) or less. If the
gauge pointer is near 125°C
(260°F), the engine is too hot.
It means that the engine coolant has
overheated. If the vehicle has been
operating under normal driving
conditions, pull off the road, stop the
vehicle, and turn off the engine as
soon as possible.
See Engine Overheating 0250 for
more information.

Engine Coolant
Temperature Warning
Light
The engine coolant temperature
warning light comes on briefly when
the vehicle is started.
If it does not, have the vehicle
serviced by your dealer. If the
system is working normally, the
indicator light then goes off.
If the light comes on and stays on
while driving, the vehicle may have
a problem with the cooling system. Stop and turn off the vehicle to
avoid damage to the engine.
A warning chime sounds when this
light is on.
See
Engine Overheating 0250 for
more information.
Tire Pressure Light
For vehicles with the Tire Pressure
Monitor System (TPMS), this light
comes on briefly when the engine is
started. It provides information
about tire pressures and the TPMS.
When the Light Is On Steady
This indicates that one or more of
the tires are significantly
underinflated.
A Driver Information Center (DIC)
tire pressure message may also
display. See Tire Messages 0133.
Stop as soon as possible, and inflate the tires to the pressure value
shown on the Tire and Loading
Information label. See

problem with the TPMS. If the
problem is not corrected, the light
will come on at every ignition cycle.
See Tire Pressure Monitor
Operation 0277.Engine Oil Pressure Light
Oil pressure can vary with engine
speed, outside temperature, and oil
viscosity.
On some models, the oil pump will
vary engine oil pressure according
to engine needs. Oil pressure may
change quickly as the engine speed
or load varies. This is normal. If the
oil pressure warning light or Driver
Information Center (DIC) message
indicates oil pressure outside the
normal operating range, check the
vehicle's oil as soon as possible.

202 Driving and Operating
race the engine immediately
after starting it. Operate the
engine and transmission gently
to allow the oil to warm up and
lubricate all moving parts.
Caution
Cranking the engine for long
periods of time, by returning the
ignition to the START position
immediately after cranking has
ended, can overheat and damage
the cranking motor, and drain the
battery. Wait at least 15 seconds
between each try, to let the
cranking motor cool down.
2. If the engine does not start after five to 10 seconds,
especially in very cold weather
(below −18 °C or 0 °F), it could
be flooded with too much
gasoline. Try pushing the
accelerator pedal all the way to
the floor and holding it there as
you hold the key in START for
up to a maximum of
15 seconds. Wait at least
15 seconds between each try, to allow the cranking motor to
cool down. When the engine
starts, let go of the key and
accelerator. If the vehicle starts
briefly but then stops again,
repeat these steps. This clears
the extra gasoline from the
engine. Do not race the engine
immediately after starting it.
Operate the engine and
transmission gently until the oil
warms up and lubricates all
moving parts.
Engine Heater
The engine coolant heater can
provide easier starting and better
fuel economy during engine
warm-up in cold weather conditions
at or below 0 °F (−18 °C). Vehicles
with an engine coolant heater
should be plugged in at least four
hours before starting. Some models
may have an internal thermostat in
the cord which will prevent engine
coolant heater operation at
temperatures above 0 °F (−18 °C).
To Use the Engine Coolant
Heater
1. Turn off the engine.
2. Open the hood and unwrap the
electrical cord. The bundled
cord is located on the driver
side of the engine
compartment, between the
engine air cleaner and the
windshield washer fluid
reservoir. See Engine
Compartment Overview 0240.
Check the heater cord for
damage. If it is damaged, do
not use it. See your dealer for
a replacement. Inspect the
cord for damage yearly.
3. Plug the cord into a normal, grounded 110-volt AC outlet.

9955666) - 2017 - crc - 8/4/16
230 Driving and Operating
When turning with a trailer, make
wider turns than normal so the
trailer will not strike soft shoulders,
curbs, road signs, trees or other
objects. Use the turn signal well in
advance and avoid jerky or sudden
maneuvers.
Turn Signals When Towing a
Trailer
The turn signal indicators on the
instrument cluster flash whenever
signaling a turn or lane change.
Properly hooked up, the trailer
lamps also flash, telling other
drivers the vehicle is turning,
changing lanes or stopping.
When towing a trailer, the arrows on
the instrument cluster flash for turns
even if the bulbs on the trailer are
burned out. Check occasionally to
be sure the trailer bulbs are still
working.
Driving on Grades
Reduce speed and shift to a lower
gear before starting down a long or
steep downgrade. If the
transmission is not shifted down, thebrakes might have to be used so
much that they would get hot and no
longer work well.
The vehicle can tow in D (Drive).
Use a lower gear if the transmission
shifts too often.
The Tow/Haul Mode may be used if
the transmission shifts too often.
See
Tow/Haul Mode 0209.
When towing at high altitude on
steep uphill grades, engine coolant
boils at a lower temperature than at
normal altitudes. If the engine is
turned off immediately after towing
at high altitude on steep uphill
grades, the vehicle could show
signs similar to engine overheating.
To avoid this, let the engine run
while parked, preferably on level
ground, with the transmission in
P (Park) for a few minutes before
turning the engine off. If the
overheat warning comes on, see
Engine Overheating 0250.
Parking on Hills
{Warning
Parking the vehicle on a hill with
the trailer attached can be
dangerous. If something goes
wrong, the rig could start to move.
People can be injured, and both
the vehicle and the trailer can be
damaged. When possible, always
park the rig on a flat surface.
If parking the rig on a hill: 1. Press the brake pedal, but do not shift into P (Park) yet. Turn
the wheels into the curb if
facing downhill or into traffic if
facing uphill.
2. Have someone place chocks under the trailer wheels.
3. When the wheel chocks are in place, release the brake pedal
until the chocks absorb
the load.
4. Reapply the brake pedal. Then apply the parking brake and
shift into P (Park).
