134 STARTING AND OPERATING
The starter motor will engage automatically, run for
10 seconds, and then disengage. Once this occurs,
release the accelerator pedal and the brake pedal,
wait 10 to 15 seconds, then repeat the "Normal
Starting" procedure.
WARNING!
Never pour fuel or other flammable liquid into

the throttle body air inlet opening in an
attempt to start the vehicle. This could result
in flash fire causing serious personal injury.
Do not attempt to push or tow your vehicle to

get it started. Vehicles equipped with an auto-
matic transmission cannot be started this
way. Unburned fuel could enter the catalytic
converter and once the engine has started,
ignite and damage the converter and vehicle.
If the vehicle has a discharged battery,

booster cables may be used to obtain a start
from a booster battery or the battery in
another vehicle. This type of start can be
dangerous if done improperly Ú page 376.
CAUTION!
To prevent damage to the starter, do not crank
the engine for more than 10 seconds at a time.
Wait 10 to 15 seconds before trying again.
If the engine has been flooded, it may start to run,
but not have enough power to continue running
when the ignition button/key is released. If this
occurs, continue cranking with the accelerator
pedal pushed all the way to the floor. Release the
accelerator pedal and the ignition button/key once
the engine is running smoothly.
If the engine shows no sign of starting after a
10 second period of engine cranking with the
accelerator pedal held to the floor, wait 10 to
15 seconds, then repeat the "Normal Starting"
procedure.

STARTING THE ENGINE — DIESEL ENGINE
Before starting your vehicle, adjust your seat,
adjust both inside and outside mirrors, and fasten
your seat belts.
The starter should not be operated for more than
25-second intervals. Waiting a few minutes
between such intervals will protect the starter from
overheating.
WARNING!
Do not leave children or animals inside parked

vehicles in hot weather. Interior heat build-up
may cause serious injury or death.
When leaving the vehicle, always make sure

the keyless ignition node is in the OFF posi-
tion, remove the key fob from the vehicle and
lock the vehicle.
Never leave children alone in a vehicle, or with

access to an unlocked vehicle. Allowing chil-
dren to be in a vehicle unattended is
dangerous for a number of reasons. A child or
others could be seriously or fatally injured.
Children should be warned not to touch the
parking brake, brake pedal or the gear
selector.
Do not leave the key fob in or near the vehicle,

or in a location accessible to children, and do
not leave the ignition of a vehicle equipped
with Keyless Enter 'n Go™ in the ACC or
ON/RUN position. A child could operate power
windows, other controls, or move the vehicle.
