M (Manual Mode).
2. Press the +/− buttons on the
shift lever, to select the desired
range of gears for current driving
conditions.
When M (Manual Mode) is selected,

transmitters no longer work once the
new transmitter is programmed.
Each vehicle can have up to
four transmitters programmed to it.
Battery Replacement
Replace the battery if the REPLACE
BATTERY IN REMOTE KEY
message displays in the DIC. See
“REPLACE BATTERY IN REMOTE
KEY”under Key and Lock
Messages on page 5‑33 for
additional information.
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
This vehicle may have a remote
start feature. This feature allows you
to start the engine from outside the
vehicle. It may also start the
vehicle's heating or air conditioning
systems. See Climate Control
Systems on page 8‑1 for additional
information.
Laws in some local communities
may restrict the use of remote
starters. For example, some laws
may require a person using remote
start to have the vehicle in view
when doing so. Check local
regulations for any requirements on
remote starting of vehicles.
Do not use the remote start feature
if the vehicle is low on fuel. The
vehicle may run out of fuel.

Do not use the lighter to plug in
accessory devices. Use the power
outlets provided.
Notice:Holding a cigarette lighter
in while it is heating does not let
the lighter back away from the
heating element when it is hot.
Damage from overheating can
occur to the lighter or heating
element, or a fuse could be
blown. Do not hold a cigarette
lighter in while it is heating.
Ashtrays
The vehicle may have a removable
ashtray. The ashtray can be placed
into the front floor console
cupholder. Open cover to use.
Notice: If papers, pins, or other
flammable items are put in the
ashtray, hot cigarettes or other
smoking materials could ignite
them and possibly damage the
vehicle. Never put flammable
items in the ashtray.
Warning Lights,
Gauges, and
Indicators
Warning lights and gauges can
signal that something is wrong
before it becomes serious enough
to cause an expensive repair or
replacement. Paying attention to the
warning lights and gauges could
prevent injury.
Warning lights come on when there
could be a problem with a vehicle
function. Some warning lights come
on briefly when the engine is started
to indicate they are working.
Gauges can indicate when there
could be a problem with a vehicle
function. Often gauges and warning
lights work together to indicate a
problem with the vehicle. When one of the warning lights
comes on and stays on while
driving, or when one of the gauges
shows there may be a problem,
check the section that explains what
to do. Follow this manual's advice.
Waiting to do repairs can be costly
and even dangerous.

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
will read 100°C (210°F) or less.
If the vehicle is pulling a load or
going up hills, it is normal for the
temperature to fluctuate and
approach the 122°C (250°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 10‑20.
Voltmeter Gauge
When the engine is not running, but
the ignition is on, this gauge shows
the battery's state of charge in
DC volts.
When the engine is running, the
gauge shows the condition of the
charging system. Readings between
the low and high warning zones
indicate the normal operating range. Readings in the low warning zone
may occur when a large number of
electrical accessories are operating
in the vehicle and the engine is left
at an idle for an extended period.
This condition is normal since the
charging system is not able to
provide full power at engine idle. As
engine speeds are increased, this
condition should correct itself as
higher engine speeds allow the
charging system to create maximum
power.
The vehicle can be only driven for a
short time with the reading in either
warning zone. If it must be driven,
turn off all unnecessary
accessories.
Readings in either warning zone
indicate a possible problem in the
electrical system. Have the vehicle
serviced as soon as possible.

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 the vehicle.

5-32 Instruments and Controls
This message displays and a chime
sounds 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 10‑8 for

information.
ENGINE OIL LOW ADD OIL
If the vehicle has an oil level sensor,
this message displays if the oil level
in the vehicle is low. Check the oil
level and correct it as necessary.
You may need to let the vehicle cool
or warm up and cycle the ignition to
be sure this message clears. See
Engine Oil on page 10‑6 for
additional information.
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 10‑6 for 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 10‑6.
Engine Power Messages
ENGINE POWER IS REDUCED
This message displays and a chime
sounds when the cooling system
temperature gets too hot and the
engine further enters the engine
coolant protection mode. See
Engine Overheating on page 10‑20
for further information.
This message also displays when
the 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
