HOW TO START THE ENGINE
Cranking hold function
Once you turn the ignition key to STARTº position and release
it, the cranking hold function continues to crank the engine in
ONº position until it starts.
The function stops cranking the engine after about 25 seconds
maximum if the engine has not started yet. When you crank
the engine again, wait a few seconds and restart it.
If you hold the key in STARTº position, the function will keep
cranking for about 30 seconds maximum.
Before cranking
1. Apply the parking brake firmly.
2. Turn off unnecessary lights and accessories.
3. Put the selector lever in Pº. If you need to restart the engine
while the vehicle is moving, put the selector lever in Nº. A
starter safety device will prevent the starter from operating if
the selector lever is in any drive position.
4. Depress the brake pedal and hold it to the floor until driving
off.
Starting the engine
Before starting the engine, be sure to follow the instructions in
Before crankingº.
Normal starting procedure
The multiport fuel injection system/sequential multiport fuel
injection system in your engine automatically controls the
proper air-fuel mixture for starting. You can start a cold or hot
engine as follows:
With your foot off the accelerator pedal, turn the ignition key to
STARTº position, then release it.
Engine should be warmed up by driving, not in idle. For
warming up, drive with smoothly turning engine until engine
coolant temperature is within normal range.
If the engine stalls...
Simply restart it, using the correct procedure given in normal
starting.
If the engine will not start...
See If your vehicle will not startº on page 481.
NOTICE
Do not race a cold engine.
If the engine becomes difficult to start or stalls frequently, have the engine checked immediately.

(g) If you cannot shift the selector lever
If you cannot shift the selector lever even though the brake
pedal is depressed, use the shift lock override button. For
instructions, see If you cannot shift automatic transmission
selector leverº on page 513.
(h) Driving in second start mode
In the second start mode, the transmission system shifts up
from second gear. Use this mode when starting your vehicle
in sand, mud, ice or snow.
To set the second start mode, push the 2nd STRTº switch. In
the second start mode, the 2nd STRTº indicator light comes
on. To cancel the second start mode, push the 2nd STRTº
switch once again.
FOUR-WHEEL DRIVE SYSTEM
(a) Four-wheel drive control
Use the four-wheel drive control lever and center
differential lock button to select the following transfer and
center differential modes.
The Hº and Lº position of the four-wheel drive control lever
provides either lock or unlock mode of the center differential
depending on the center differential lock button position.
Use the center differential lock system if your wheels get stuck
in a ditch, or when you are driving on a slippery or bumpy
surface. When the center differential is locked, the vehicle
stability control system is automatically turned off and the
center dif ferential lock and VSC OFFº indicator lights come on
because the function that controls engine performance
interferes with the process of freeing your wheels.
