STARTING AND DRIVING
225
IGNITION SWITCH WITH STEERINGLOCK
“START” Starter motor on. The key will return to the
“ON” position when released.
For starting tips, see page 226.
“ON” Engine on and all accessories on.
This is the normal driving position.
NOTICE
Do not leave the key in the “ON” position if the engine
is not running. The battery will discharge and the
electronic ignition system could be damaged.
“ACC” Accessories such as the radio operate, but the
engine is off. If you leave the key in the “ACC” or “LOCK” position and open
the driver’s door, a buzzer will remind you to remove the key.
“LOCK” Engine is off and the steering wheel is locked.
The ignition key can be removed only at this position.
To turn the ignition switch from “ACC” to the “LOCK” position,\
you must put the transmission selector lever in the “P”
position.
Once you remove the key, the engine immobiliser system is
automatically set. See “Engine immobiliser system” on page
14.
When starting the engine, the key may seem stuck at the
“LOCK” position. To free it, first be sure the key is pushed all
the way in, and then rock the steering wheel slightly while
turning the key gently.
If, in an emergency, you must turn the engine off while the
vehicle is moving, turn the key only to “ACC”.

STARTING AND DRIVING
227
If the weather is below freezing, let the engine warm up for a
few minutes before driving. Do not leave the vehicle while the
engine is warming up.
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 start” on page 264.
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 stalls
frequently, 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 “P” position when the
brake pedal is depressed with the ignition switch in “ON”
position. ( )
31E158

STARTING AND DRIVING
228
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)
4: Position for engine braking (shifting into overdrive not
possible)
When the cruise control is being used, even if you
downshift from “D” to “4”, engine braking will not be
enabled because the cruise control is not cancelled. For
the operation to decrease the vehicle speed, see page
236.
3, 2: Position for more powerful engine braking
L: Position for maximum engine braking Correct
use of the automatic transmission is explained in
the following parts.
(a) Normal driving
(b) Using engine braking
(c) Using the “3”, “2” and “L” positions
(d) Backing up
(e) Parking
(f) Good driving practice
(g) If you cannot shift the selector lever

STARTING AND DRIVING
2303. Release the parking brake and brake pedal. Depress
the accelerator pedal slowly for smooth starting.
In normal cruising, the vehicle will start in 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 the “4” 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 auto matically 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 “(b) Using engine braking”.
(b) Using engine braking
To use the braking power of the engine, downshift the
transmission in the way described below:
1 Shift into the “4” position. The transmission will downshift
to fourth gear and engine braking will be enabled.
When the cruise control is being used, even if you
downshift from “D” to “4”, engine braking will not be
applied because the cruise control is not cancelled. If you
need to decrease the vehicle speed, see page 236.
2 Shift into the “3” position. The transmission will downshift
to third gear when the vehicle speed is or becomes lower
than 147 km/h (91 mph) and more powerful engine
braking will be enabled.

STARTING AND DRIVING
231
3Shift into the “2” position. The transmission will downshift
to second gear when the vehicle speed is or becomes
lower than 95 km/h (59 mph) and more powerful engine
braking than that of “3” position will be enabled.
4 Shift into the “L” position. The transmission will downshift
to first gear when the vehicle speed is or becomes lower
than 41 km/h (25 mph) and maximum engine braking will
be enabled.
CAUTION
Be careful when downshifting on a slippery surface.
The abrupt change in engine speed could cause the
vehicle to spin or skid.
(c) Using the “3”, “2” and “L” positions
The “3”, “2” and “L” positions are used for strong engine
braking as described previously.
With the selector lever in “3”, “2” or “L”, you can start the vehicle
in motion as with the lever in “D”.
With the selector lever in “3” or “2”, the vehicle will start in firs\
t
gear and automatically shift to second gear or third gear.
With the selector lever in “L”, the transmission is engaged in
first gear.
NOTICE
 Be careful not to overrev the engine. Watch the
tachometer to keep engine rpm from going into the
red zone. The approximate maximum allowable
speed for each position is given above for your
reference.
“3” 147 km/h (91 mph) . . .
“2” 94 km/h (58 mph) . . .
“L” 52 km/h (32 mph) . . .
 Do not continue hill climbing or hard towing for a long
time in the “3”, “2” or “L” position. This may cause
severe automatic transmission damage from
overheating. To prevent such damage, “4” position
should be used in hill climbing or hard towing.

STARTING AND DRIVING
233
(f) Good driving practice
If the transmission repeatedly shifts up and down between
fourth and overdrive gears when climbing a gentle slope,
shift the selector lever to the “4” position. Be sure to shift the
selector lever to the “D” position after climbing the slope.
 When towing a trailer, in order to maintain efficient engine
braking and electrical charging performance, do not use
overdrive.
CAUTION
Always keep your foot on the brake pedal while stopped
with the engine running. This prevents the vehicle from
creeping.
NOTICE
Always use the brake pedal or the parking brake to hold
the vehicle on an upgrade. Do not attempt to hold the
vehicle using the accelerator pedal, as this can cause
the transmission to overheat.
(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 lever” on page 284.

STARTING AND DRIVING
234
CRUISE CONTROL
The cruise control allows you to cruise the vehicle at a
desired speed over 40 km/h (25 mph) with your foot off the
accelerator pedal.
Your cruising speed can be maintained although a slight speed
change may occur when driving up or down a gradient, within
the limits of engine performance. On steeper hills, a great
speed change will occur so it is better to drive without the cruise
control.
CAUTION
 To help maintain maximum control of your vehicle,
do not use the cruise control when driving in heavy
or varying traffic, or on slippery (rainy, icy or
snowcovered) or winding roads.
 Avoid vehicle speed increases when driving
downhill. If the vehicle speed is too fast in relation to
the cruise control set speed, cancel the cruise
control then downshift the transmission to use
engine braking to slow down.
Turning on the system
To operate the cruise control, push the main switch. This turns
the system on. The indicator light in the instrument cluster
shows that you can now set your desired cruising speed.
Another push on the switch will turn the system completely off.
When the ignition key is turned off, the main switch is also
automatically turned off. To use the cruise control again, push
the main switch again to turn it on.
CAUTION
To avoid accidental cruise control engagement, keep
the main switch off when not using the cruise control.
