Section 2 Features and Controls
2-1

Once two remote starts or a single start with a time
extension have been provided, the vehicle must
be started normally with the ignition key to get more
remote vehicle starts.
The remote vehicle start feature will not operate if the
key is in the ignition, the hood is not closed, or if there is
an emission control system malfunction.
The engine will turn off during a remote vehicle start if
the coolant temperature gets too high, or the oil pressure
is too low.
Your vehicle was shipped from the factory with the
remote vehicle start system enabled. The system may
be disabled through the Driver Information Center (DIC).
See “REMOTE START” underDIC Vehicle
Customization on page 3-88for additional information.
SeeEngine Exhaust on page 2-33for important
safety information when using remote start in a
closed garage.Doors and Locks
Door Locks
{CAUTION:
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. You increase the chance
of being thrown out of the vehicle in a
crash if the doors are not locked. So, wear
safety belts properly and lock the doors
whenever you drive.
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 death
from heat stroke. Always lock your vehicle
whenever you leave it.
Outsiders can easily enter through an
unlocked door when you slow down or
stop your vehicle. Locking your doors can
help prevent this from happening.
2-10

Notice:Holding your key in START for longer than
15 seconds at a time will cause your battery to
be drained much sooner. And the excessive heat
can damage your starter motor. Wait about
15 seconds between each try to help avoid draining
your battery or damaging your starter.
2. If the engine does not start within 10 seconds, hold
your key in START for about 10 seconds at a time
until the engine starts. Wait about 15 seconds
between each try.
When your engine has run for about 10 seconds
to warm up, your vehicle is ready to be driven.
Do not race your engine when it is cold.
If the weather is below freezing (32°F or 0°C), let
the engine run for a few minutes to warm up.
3. If your engine still will not start, or starts but then
stops, it could be ooded with too much gasoline.
Try pushing your accelerator pedal all the way to
the oor and holding it there as you hold the key in
START for about three seconds. If the vehicle
starts briey but then stops again, do the same
thing. This time keep the pedal down for ve or
six seconds to clear the extra gasoline from
the engine. After waiting about 15 seconds,
repeat the normal starting procedure.Notice:Your engine is designed to work with the
electronics in your vehicle. If you add electrical
parts or accessories, you could change the way the
engine operates. Before adding electrical equipment,
check with your dealer. If you do not, your engine
might not perform properly. Any resulting damage
would not be covered by your vehicle’s warranty.
Engine Coolant Heater
Your vehicle may have an engine coolant heater.
In very cold weather, 0°F (−18°C) or colder, the engine
coolant heater can help. You will get easier starting
and better fuel economy during engine warm-up.
Usually, the coolant heater should be plugged in a
minimum of four hours prior to starting your vehicle.
At temperatures above 32°F (0°C), use of the coolant
heater is not required.
2-25

To Use the Engine Coolant Heater
1. Turn off the engine.
2. Open the hood and unwrap the electrical cord.
The electrical cord is located on the driver’s side
of the engine, behind the transaxle dipstick/uid ll
location and next to the engine.
3. Plug it into a normal, grounded 110-volt AC outlet.
{CAUTION:
Plugging the cord into an ungrounded outlet
could cause an electrical shock. Also, the
wrong kind of extension cord could overheat
and cause a re. You could be seriously
injured. Plug the cord into a properly grounded
three-prong 110-volt AC outlet. If the cord will
not reach, use a heavy-duty three-prong
extension cord rated for at least 15 amps.
4. Before starting the engine, be sure to unplug and
store the cord as it was before to keep it away
from moving engine parts. If you do not, it could be
damaged.How long should you keep the coolant heater plugged
in? The answer depends on the outside temperature, the
kind of oil you have, and some other things. Instead
of trying to list everything here, we ask that you contact
your dealer in the area where you will be parking
your vehicle. The dealer can give you the best advice
for that particular area.
Automatic Transaxle Operation
The automatic transaxle may have a shift lever located
either on the steering column or on the console
between the seats.
There are several different positions for the shift lever.
PARK (P):This position locks the front wheels. It is the
best position to use when you start the engine because
your vehicle cannot move easily.
