Notice:When replacing the
battery, do not touch any of
the circuitry on the transmitter.
Static from your body could
damage the transmitter.
To replace the battery:
1. Separate the transmitter with a flat, thin object, such as a flat
head screwdriver.
.Carefully insert the tool into
the notch located along the
parting line of the transmitter. Do not insert
the tool too far. Stop as
soon as resistance is felt.
.Twist the tool until the
transmitter is separated.
2. Remove the old battery. Do not use a metal object.
3. Insert the new battery, positive side facing down. Replace with a
CR2032 or equivalent battery.
4. Snap the transmitter back together.
Remote Vehicle Start
The vehicle may have a remote
starting feature. This feature allows
you to start the engine from outside
of the vehicle. It may also start
up the vehicle's heating or air
conditioning systems and rear
window defogger. Normal operation
of the system will return after the
key is turned to the ON/RUN
position. If the vehicle has an automatic
climate control system, the climate
control system will default to a
heating or cooling mode depending
on the outside temperatures. If the
vehicle does not have an automatic
climate control system, the system
will turn on at the setting the vehicle
was set to when the vehicle was
last turned off.
During a remote start, if the vehicle
has an automatic climate control
system and heated seats, the
heated seats will turn on during
colder outside temperatures and
will shut off when the key is turned
to ON/RUN. If the vehicle does
not have an automatic climate
control system, during remote
start, manually turn the heated
seats on and off. See
Heated
Front Seats
on page 3‑11for
additional information.

5-20 Instruments and Controls
English
This gauge shows the engine
coolant temperature.
It also provides an indicator of
how hard the vehicle is working.
During a majority of the operation,
the gauge reads 100°C (210°F) or
less. If pulling a load or going up
hills, it is normal for the temperature
to fluctuate and go over the 113°C
(235°F) mark. If the gauge reaches
the 125°C (260°F) mark, it indicates
that the cooling system is working
beyond its capacity. See
Engine Overheating
on
page 10‑24.
If the vehicle is a hybrid, see the
hybrid supplement for more
information.
Voltmeter Gauge
For vehicles with a voltmeter gauge,
this gauge indicates the battery
voltage when the ignition is
turned on. When the ignition is on, this gauge
indicates the battery voltage.
When the engine is running, this
gauge shows the condition of the
charging system. The gauge can
transition from a higher to lower
or a lower to higher reading. This is
normal. If the vehicle is operating
outside the normal operating range,
the charging system light comes on.
See
Charging System Light
on
page 5‑26for more information.
The voltmeter gauge may also read
lower when in fuel economy mode.
This is normal.

RIGHT REAR DOOR OPEN
(Crew Cab)
This message displays and a chime
may sound if the passenger side
rear door is not fully closed and the
vehicle is shifted out of P (Park).
Stop and turn off the vehicle, check
the door for obstructions, and close
the door again. Check to see if the
message still appears on the DIC.
Engine Cooling System
Messages
ENGINE HOT A/C (Air
Conditioning) TURNED OFF
This message displays when the
engine coolant becomes hotter than
the normal operating temperature.
SeeEngine Coolant Temperature
Gauge
on page 5‑19. To avoid
added strain on a hot engine,
the air conditioning compressor
automatically turns off. When the
coolant temperature returns to normal, the air conditioning
compressor turns back on. You can
continue to drive your vehicle.
If this message continues to appear,
have the system repaired by your
dealer as soon as possible to avoid
damage to the engine.
ENGINE OVERHEATED IDLE
ENGINE
Notice:
If you drive the vehicle
while the engine is overheating,
severe engine damage may
occur. If an overheat warning
appears on the instrument panel
cluster and/or DIC, stop the
vehicle as soon as possible.
See Engine Overheating
on
page 10‑24for more information.
This message displays when the
engine coolant temperature is too
hot. Stop and allow the vehicle to
idle until it cools down. See Engine
Coolant Temperature Gauge
on
page 5‑19. See
Overheated Engine Protection
Operating Mode
on page 10‑26for
information on driving to a safe
place in an emergency.
ENGINE OVERHEATED STOP
ENGINE
Notice: If you drive the vehicle
while the engine is overheating,
severe engine damage may
occur. If an overheat warning
appears on the instrument panel
cluster and/or DIC, stop the
vehicle as soon as possible.
See Engine Overheating
on
page 10‑24for more information.
This message displays and a
chime may sound if the engine
cooling system reaches unsafe
temperatures for operation. Stop
and turn off the vehicle as soon as
it is safe to do so to avoid severe
damage. This message clears when
the engine has cooled to a safe
operating temperature.

Engine Oil Messages
CHANGE ENGINE OIL SOON
This message displays when the
engine oil needs to be changed.
When you change the engine oil,
be sure to reset the CHANGE
ENGINE OIL SOON message.
SeeEngine Oil Life System
on
page 10‑9for information on how
to reset the message. See Engine
Oil
on page 10‑7and Scheduled
Maintenanceon page 11‑2for
more information.
ENGINE OIL HOT IDLE
ENGINE
This message displays when the
engine oil becomes hotter than the
normal operating temperature. Stop
and allow the vehicle to idle until it
cools down. See Engine Coolant
Temperature Gauge
on page 5‑19.
OIL PRESSURE LOW STOP
ENGINE
Notice: If you drive the vehicle
while the engine oil pressure
is low, severe engine damage
may occur. If a low oil pressure
warning appears on the Driver
Information Center (DIC), stop
the vehicle as soon as possible.
Do not drive the vehicle until the
cause of the low oil pressure is
corrected. See Engine Oil
on
page 10‑7for more information.
This message displays if low oil
pressure levels occur. Stop the
vehicle as soon as safely possible
and do not operate it until the cause
of the low oil pressure has been
corrected. Check the oil as soon
as possible and have the vehicle
serviced by your dealer. See Engine
Oil on page 10‑7.
Engine Power Messages
ENGINE POWER IS REDUCED
This message displays and a
chime may sound when the cooling
system temperature gets too hot
and the engine further enters the
engine coolant protection mode.
See Engine Overheating
on
page 10‑24for more information.
This message also displays when
the vehicle's engine power is
reduced. Reduced engine power
can affect the vehicle's ability
to accelerate. If this message
is on, but there is no reduction
in performance, proceed to your
destination. The performance may
be reduced the next time the vehicle
is driven. The vehicle may be driven
at a reduced speed while this
message is on, but acceleration and
speed may be reduced. Anytime
this message stays on, the vehicle
should be taken to your dealer for
service as soon as possible.

Lighting 6-9
Lighting Features
Entry Lighting
The vehicle has an illuminated entry
feature.
When the doors are opened, the
dome lamps will come on if the
dome override button is in the
extended position. If the dome
override button is pressed in,
the lamps will not come on.
Exit Lighting
The interior lamps come on when
the key is removed from the ignition.
They turn off automatically in
20 seconds. The lights do not come
on if the dome override button is
pressed in.
Battery Load
Management
The vehicle has Electric Power
Management (EPM) that estimates
the battery's temperature and state
of charge. It then adjusts the voltage
for best performance and extended
life of the battery.
When the battery's state of charge
is low, the voltage is raised slightly
to quickly bring the charge back up.
When the state of charge is high,
the voltage is lowered slightly to
prevent overcharging. If the vehicle
has a voltmeter gauge or a voltage
display on the Driver Information
Center (DIC), you may see the
voltage move up or down. This is
normal. If there is a problem, an
alert will be displayed.The battery can be discharged at
idle if the electrical loads are very
high. This is true for all vehicles.
This is because the generator
(alternator) may not be spinning
fast enough at idle to produce all
the power that is needed for very
high electrical loads.
A high electrical load occurs when
several of the following are on,
such as: headlamps, high beams,
fog lamps, rear window defogger,
climate control fan at high speed,
heated seats, engine cooling fans,
trailer loads, and loads plugged into
accessory power outlets.
EPM works to prevent excessive
discharge of the battery. It does this
by balancing the generator's output
and the vehicle's electrical needs.
It can increase engine idle speed
to generate more power, whenever
needed. It can temporarily reduce
the power demands of some
accessories.
