ciently). In such a case, it is recom-
mended that you change to a different
brand of fuel.
 On rare occasions, transient
knocking may be heard from the
engine when the accelerator is oper-
ated rapidly such as a rapid start-up
and a rapid acceleration. This is not a

■ Shifting Speeds▼ Recommended shifting speeds
The best compromise between fuel
economy and vehicle performance during
normal driving is ensured by shifting up at
the speeds listed in the following table. ▼
Gear shift indicator
1) Upshift indicator
2) Gear position indicatorThe gear position indicator shows the
position of the shift lever.
When shifting up is recommended for
good fuel economy, the upshift indicator
blinks.
The gear shift indicator can be activated
or deactivated. The default setting is
deactivated. For details, refer to "Settings
Display" P157.
WARNING
 Do not drive the vehicle with the
clutch disengaged (i.e., when the
clutch pedal is depressed) or with
the shift lever in the neutral posi-
tion. Engine braking has no effect
in either of these conditions and
the risk of an accident is conse-
quently increased.
1702835
 Do not engage the clutch (i.e.,
release the clutch pedal)
suddenly when starting the
vehicle. By doin g so the vehicle
might unexpectedly accelerate or
the transmission could malfunc-
tion.
CAUTION
 Shift into reverse ONLY when the
vehicle has completely stopped.
It may cause damage to the trans-
mission to try shifting into
reverse when the vehicle is
moving. Do not shift the shift lever without
depressing the clutch pedal.

■Driving TipsNOTEIf the accelerator and brake pedals are
depressed at the same time, driving
torque may be restrained. This is not a
malfunction.
Do not drive with your foot resting on the
clutch pedal and do not use the clutch to
hold your vehicle at a standstill on an
upgrade. Either of those actions may
cause clutch damage.
Do not drive with your hand resting on the
shift lever. This may cause wear on the
transmission components. When it is necessary to reduce vehicle

speed due to slow traffic, turning corners,
or driving up steep hills, downshift to a
lower gear before the engine starts to
labor.
On steep downgrades, downshift the
transmission to 5th, 4th, 3rd or 2nd gear
as necessary; this helps to maintain a safe
speed and to extend brake pad life.
In this way, the engine provides a braking
effect. Remember, if you “ride” (over use)
the brakes while descending a hill, they
may overheat and not work properly.
The engine may, on rare occasions, knock
when the vehicle rapidly accelerates or
rapidly pulls away from a standstill. This
phenomenon is not an indication of a
problem in your vehicle.
With the exception of cases where sudden
acceleration is required, do not drive the
vehicle with the pointer of the tachometer
inside the red area. Failure to observe this
precaution can lead to excessive engine
wear and poor fuel economy.
7-6. Automatic TransmissionThe automatic transmission is electroni-
cally controlled and provides 6 forward
speeds and 1 reverse speed. It also has a
manual mode.
WARNING
When shifting down a gear, ensure
that the engine speed does not
enter the red zone. Failure to
observe this precaution can lead to
engine over-revving and this in turn
can result in engine damage.In addition, sudden application of
engine brakes when the vehicle is
travelling on a slippery surface can
lead to wheel locking; as a conse-
quence, control of the vehicle may
be lost and the risk of an accident
increased.
WARNING
Do not shift from the “P” or “N”
position into the “D” or “R” position
while depressing the accelerator
pedal. This may cause the vehicle to
lurch forward or backward.
CAUTION
 Observe the following precau-
tions. Failure to observe these
precautions could cause damage
to the transmission.
- Shift into the “P” or “R” posi- tion only after the vehicle has
completely stopped.- Do not shift from the “D” posi- tion into the “R” position or
vice versa until the vehicle
has completely stopped.

Starting and Operating7
– CONTINUED –
7-17. Hill Start Assist SystemThe Hill start assist system is a device to
make the following vehicle operations
easier.
1) Starting forward facing uphill
2) Starting backward facing downhill
A) Brake pedal (both MT models and AT
models)
B) Clutch pedal (MT models only)
In both these cases, the Hill start assist
system operates under the following
conditions.
 The clutch pedal is depressed while the
brake pedal is also depressed (MT
models).
 The vehicle has stopped with the brake
pedal depressed (AT models).
Braking power is maintained temporarily
(for approximately 2 seconds) by the Hill
start assist system after the brake pedal is
released. The driver is therefore able to
start the vehicle in the same way as on a
level grade, just using the clutch pedal
(MT models only) and accelerator pedal
(all models).
If the braking power of the Hill start assist
system is insufficient after the brake pedal
is released, apply more braking power by
depressing the brake pedal again.
The Hill start assist system may not
operate on slight grades. Also, the Hill
start assist system does not operate in the
following cases.
WARNING
 The Hill start assist system is a
device only for helping the driver
to START the vehicle on an uphill
grade. To prevent accidents when
the vehicle is parked on a slope,
be sure to firmly set the parking
brake. When setting the parking
brake, make sure that the vehicle
remains stationary when the
clutch pedal (MT models) and
brake pedal (both MT and AT
models) are released. Do not turn the ig nition switch to
the “OFF” position while the Hill
start assist system is operating.
The Hill start assist system will be
deactivated and may lead to an
accident.

braking effect may be felt even after the
brake pedal has been released. However,
for MT models, this braking effect should
disappear once the clutch pedal is
released.
NOTEA slight jolt may be felt when the vehi-
cle begins to move forward after being
reversed.
