346 STARTING AND OPERATING

STARTING PROCEDURES
Before starting your vehicle, adjust your seat, adjust the
inside and outside mirrors, fasten your seat belt, and if
present, instruct all other occupants to buckle their seat
belts.
WARNING!
•When leaving the vehicle, always remove the Key
Fob from the ignition and lock your vehicle.
•Never leave children alone in a vehicle, or with
access to an unlocked vehicle. Allowing children 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 shift lever.
(Continued)
WARNING!(Continued)
•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
mode. A child could operate power windows, other
controls, or move the vehicle.
Manual Transmission — If Equipped
Apply the parking brake, place the shift lever in NEU-
TRAL and press the clutch pedal before starting vehicle.
This vehicle is equipped with a clutch interlocking igni-
tion system. It will not start unless the clutch pedal is
pressed to the floor.
Normal Starting With Integrated Key — Manual
Transmission
Normal starting of either a cold or a warm engine does
not require pumping or pressing the accelerator pedal.
5
STARTING AND OPERATING 347

Press the clutch pedal fully to the floor, and cycle the
ignition switch to the START position and release when
the engine starts. If the engine fails to start within 15
seconds, place the ignition in the OFF position, wait 10 to
15 seconds, then repeat the “Normal Starting” procedure.
WARNING!
Do not attempt to push or tow your vehicle to get it
started. Unburned fuel could enter the catalytic con-
verter 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 another vehicle. This type of start
can be dangerous if done improperly, so follow the
procedure carefully. Refer to “Jump Starting” in
“What To Do In Emergencies” for further informa-
tion.
Automatic Transmission — If Equipped
The shift lever must be in the NEUTRAL or PARK
position before you can start the engine. Apply the brakes
before shifting into any driving gear.
CAUTION!
Damage to the transmission may occur if the follow-
ing precautions are not observed:
•Do not shift from REVERSE, PARK, or NEUTRAL
into any forward gear when the engine is above
idle speed.
•Shift into PARK only after the vehicle has come to
a complete stop.
•Shift into or out of REVERSE only after the vehicle
has come to a complete stop and the engine is at
idle speed.
•Before shifting into any gear, make sure your foot
is firmly on the brake pedal.
