º to º4º, engine braking will not be
applied because the cruise control is not cancelled. For the operation \
to decrease the vehicle speed, see
page 308.

STARTING AND DRIVING
291


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 ºDº to º4º, engine braking will not
be applied because the cruise control is not
cancelled. For the operation to decrease the
vehicle speed, see page 308.
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 º3º, º2º and ºLº positions
(d) Backing up
(e) Parking
(f) Good driving practice
(g) Rocking your vehicle if stuck
(h) If you cannot shift the selector lever

STARTING AND DRIVING
297
31L010b
To use the braking power of the engine, downshift the
transmission in the way described below:
1Shift into the º4º position. The transmission will
downshift to the fourth gear and engine braking will
be obtained.
When the cruise control is being used, even if you
downshift from ºDº to º4º, engine braking will not be
applied because the cruise control is not cancelled.
If you need to decrease the vehicle speed, see
page 308.
2 Shift into the º3º position. The transmission will
downshift to the third gear when the vehicle speed
is or becomes lower than 154 km/h (96 mph) and
more powerful engine braking will be obtained.
3Shift into the º2º position. The transmission will
downshift to the second gear when the vehicle
speed is or becomes lower than 104 km/h (65 mph)
and more powerful engine braking than that of º3º
position will be obtained.
4Shift into the ºLº position. The transmission will
downshift to the first gear when the vehicle speed
is or becomes lower than 18 km/h (11 mph) and
maximum engine braking will be applied.

STARTING AND DRIVING
305
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.
When the cruise control is on, the driving pattern of the
automatic transmission is fixed in the normal position,
regardless of the position of the selector switch.
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
snow±covered) 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.

STARTING AND DRIVING
306
Turning on the system
31L067
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.
