Extending Engine Run Time
The engine run time can be
extended by another 10 minutes,
if during the first 10 minutes
Steps 1–2 are repeated while the
engine is still running. This provides
a total of 20 minutes.
The remote start can only be
extended once.
When the remote start is extended,
the second 10-minute period is
added on to the first 10 minutes for
a total of 20 minutes.
A maximum of two remote starts,
or a remote start with an extension,
are allowed between ignition cycles.
The vehicle's ignition must be
changed to ON/RUN/START and
then back to OFF before the remote
start procedure can be used again.
Canceling a Remote Start
.Aim the RKE transmitter at the
vehicle and press and hold
/
until the parking lamps turn off.
.Turn on the hazard warning
flashers.
.Turn the ignition on and then off.
The vehicle can be remote started
two separate times between driving
sequences. The engine will run for
10 minutes after each remote start.
Once two remote starts, or a single
remote start with one time extension
has been done, the vehicle must be
started with the key. After the key is
removed from the ignition, the
vehicle can be remote started again.
The vehicle cannot be remote
started if the key is in the ignition,
if the hood is not closed, or if there
is an emission control system
malfunction and the malfunction
indicator lamp is on.
Also, the engine will turn off during a
remote vehicle 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. (Continued)

3-14 Seats and Restraints
.Wear the shoulder belt over the
shoulder and across the chest.
These parts of the body are best
able to take belt restraining
forces. The shoulder belt locks if
there is a sudden stop or crash.
{Warning
You can be seriously injured,
or even killed, by not wearing
your safety belt properly.
.Never allow the lap or
shoulder belt to become
loose or twisted.
.Never wear the shoulder belt
under both arms or behind
your back.
.Never route the lap or
shoulder belt over an
armrest.
Lap-Shoulder Belt
If the vehicle is a regular cab, then
all seating positions in the vehicle
have a lap-shoulder belt. If the
vehicle is a double or crew cab,
then all seating positions in the
vehicle have a lap-shoulder belt
except for the center front
passenger position (if equipped),
which has a lap belt. SeeLap Belt
on page 3-19 for more information.
The following instructions explain
how to wear a lap-shoulder belt
properly.
1. Adjust the seat, if the seat is adjustable, so you can sit up
straight. To see how, see “Seats”
in the Index. 2. Pick up the latch plate and pull
the belt across you. Do not let it
get twisted.
The lap-shoulder belt may lock if
you pull the belt across you very
quickly. If this happens, let the
belt go back slightly to unlock it.
Then pull the belt across you
more slowly.
If the shoulder portion of a
passenger belt is pulled out all
the way, the child restraint
locking feature may be engaged.
If this happens, let the belt go
back all the way and start again.
Engaging the child restraint
locking feature may affect the
passenger sensing system,
if equipped. See Passenger
Sensing System on page 3-31
for more information.
