Setting the driving position
SV16170
1. Adjust the driver's seat to the desired position.
2. While pushing the ªSETº button, push button ª1º or ª2º
until the signal beeps.
The beep sound means that the positions are recorded in the
computer's memory.
By repeating these two steps and pressing the remaining
button, the driving position for another driver can be recorded.
To set a new memorized position, select the desired position
and perform step 2. The previous memory will be erased and
the new position will be set.
To make only slight changes to an already memorized position,
the easiest way is to first activate the memorized position, then
make the desired changes and perform step 2 above.
Recalling the memorized position
SV16171
Automatic transmissionÐ
When you push button ª1º or ª2º, the driving position will
be automatically adjusted to the position recorded for
that button.
Manual transmissionÐ
While button ª1º or ª2º is being pushed down, the driving
position will be automatically adjusted to the position
recorded for that button.
Conditions for memorized position activation
 Automatic transmission: Ignition key ªONº and selector
lever in ªPº position.
 Manual transmission: Ignition key ªONº and apply the
parking brake.
 Ignition switch off and within 30 seconds of opening driver's
door.

HOW TO START THE ENGINE
Before cranking
1. Apply the parking brake firmly.
2. Turn off unnecessary lights and accessories.
3.Manual transmission : Press the clutch pedal to the floor
and shift the transmission into neutral. Hold the clutch pedal to
the floor until the engine is started. A starter safety device will
prevent the starter from operating if the clutch pedal is not fully
depressed.
Automatic transmission: Put the selector lever in ªPº. If you
need to restart the engine while the vehicle is moving, put the
selector lever in ªNº. A starter safety device will prevent the
starter from operating if the selector lever is in any drive
position.
4. For automatic transmission only :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
ªBefore 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, crank the engine by
turning the key to ªSTARTº. Release it when the engine starts. 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 ªIf your vehicle will not startº on page 281.
NOTICE
Do not crank for more than 30 seconds at a time. This
may overheat the starter and wiring systems.
Do not race a cold engine.
If the engine becomes difficult to start or stallsfrequently, have the engine checked immediately.

AUTOMATIC TRANSMISSION
Your automatic transmission has a shift lock system to
minimize the possibility of incorrect operation. This
means you can only shift out of ªPº position when the
brake pedal is depressed with the ignition switch in ªONº
position. ()
SV31020

The shift position is displayed on the instrument
cluster.
P: Parking, engine starting and key removal position
R: Reverse position
N: Neutral position
D: Normal driving position (Shifting into overdrive possible)
M: Position for manual shifting up or downshifting
When the cruise control is being used, even if you
downshift from ª5º to ª4º, engine braking will not be
enabled because the cruise control is not cancelled. For
the operation to decrease the vehicle speed, see page 251.

L: Position for maximum engine braking

Correct use of the automatic transmission is explained in
the following parts.
(a) Normal driving
(b) Driving in M mode
(c) Using engine braking
(d) Using the ª3º, ª2º and ªLº positions
(e) Backing up
(f) Parking
(g) Good driving practice
(h) If you cannot shift the selector lever

1ªPº (Park) position 2ªNº (Neutral) position
1. Start the engine as instructed in ªHow to start the
engineº on page 237.
The transmission must be in ªPº or ªNº. The engine will not sta\
rt
in any drive position even if the ignition key is turned to
ªSTARTº.
CAUTION
The selector lever knob can become extremely hot after
parking under the sun.

5. Release
the parking brake and brake pedal. Depress the
accelerator pedal slowly for smooth starting.
In normal cruising, the vehicle will start in the first gear and
automatically shift up to the most suitable gear. On inclines,
declines or winding roads, etc., the vehicle shifts up and down
automatically according to the running conditions to obtain the
suitable driving power and engine braking.
When the lever is in ª3º position, the automatic transmission
system will select the most suitable gear for the running
conditions such as hill climbing, hard towing, etc.
If you need to accelerate rapidly while driving, depress the
accelerator pedal to the full throttle position. This provides
more acceleration by automatically downshifting the
transmission to the next lower gear or beyond, depending on
the vehicle speed.
If engine braking is needed, such as in descending a long hill,
see ª(c) Using engine brakingº.
(b) Driving in M mode
If the change lever is shifted to M position, the shift range
position can be switched over between 5 and 2 using the
shift switch on the steering wheel instead of operating the
change lever. The first shift range position is on 5 when
the change lever is shifted to M position.
SV31024

1ªMº position
When the selector lever is put in the ªMº position, the M MODE
indicator is shown on the instrument cluster.

2Downshifting on the front, Upshifting on the rear
5: Fifth rangeThe most suitable gear is selected automatically
between first and fifth gears according to the vehicle speed or the running condition.
4: Fourth range The most suitable gear is selected automatically
between first and fourth gears according to the vehicle speed or the running condition. 3: Third range
The most suitable gear is selected automatically
between first and third gears according to the vehicle speed or the running condition.
Slight engine braking will be obtained on a downhill road.
Smooth running with less shifting will be obtained on an
uphill.
2: Second range First or second gear will be selected automatically
according to the vehicle speed or the running condition.
This range is used in the case that the engine braking is necessary.
The gear position being used is shown on the instrument
cluster.
Each time you push the switch located on the front of the
steering wheel, the transmission downshifts (from ª5º) to ª4º\
,
ª3º and then ª2º.
When you push the switch located on the back of the steering
wheel, the transmission upshifts to ª3º, ª4º and then ª5º\
.
For the precautions on each position, see the description on
the next page.
