Starting and operating
they may burn easily if they come near hot en-
gine or exhaust system parts.y
Be sure to stop the engine if you take a nap in
the vehicle. If engine exhaust gas enters the
passenger compartment, occupants in the ve-
hicle could die from carbon monoxide (CO)
contained in the exhaust gas.
If your vehicle has a front underspoiler and rear
underspoiler (both optional), pay attention to
blocks and other obstructions on the ground
when parking. The underspoilers could be dam-
aged by contact with them.
Cruise control
Cruise control enables you to maintain a constant ve-
hicle speed without holding your foot on the accelera-
tor pedal and it is operative when the vehicle speed is
25 mph (40 km/h) or more. Make sure the main switch
is turned “OFF” when the cruise control is not in use to
avoid unintentionally setting the cruise control.
NOTE
If you move the cruise control lever while turning
the ignition switch “ON”, the cruise control func-
tion is deactivated and the “CRUISE” indicator
light flashes. To reactivate the cruise control func-
tion, turn the ignition switch back to the “ACC” or
“LOCK” position, and then turn it again to the “ON” position.
Do not use the cruise control under any of the
following conditions. This may cause loss of
vehicle control:y driving up or down a steep grade
y driving on slippery or winding roads
ydriving in heavy traffic

COAST” direction and release it. Then release the ac-
celerator pedal.
At this time, the “ ” indicator light is illuminated in the combination meter.
The vehicle will maintain the desired speed.
Vehicle speed can be temporarily increased while
driving with the cruise control activated. Simply de-
press the accelerator pedal to accelerate the vehicle.
When the accelerator pedal is released, the vehicle
will return to and maintain the previous cruising speed. „
To temporarily cancel the cruise con- trol
There are four ways to cancel the cruise control tem-
porarily:

so equipped). y Depress the brake pedal.
y Depress the clutch pedal (manual transmission ve-
hicles only).y Shift the selector lever into the “N” position (auto-
matic transmission vehicles only). y Shift the shift lever into neutral (manual transmis-
sion vehicles only).
The “ ” indicator light in the combination meter
goes off when the cruise control is cancelled.
To resume the cruise control after it has been tempo-
rarily canceled and with vehicle speed of about 20 mph (32 km/h) or more, push the control lever upward
in the “RES/ACC” direction to return to the original
cruising speed automatically.
The “ ” indicator light in the combination meter
will automatically come on at this time. „
To turn off the cruise control
There are two ways to turn off the cruise control: y Push the main switch again.
y Turn the ignition switch to the “ACC” or “LOCK” po-
sition (but only when the vehicle is completely
stopped).

To change the cruising speed
T To increase the speed (by control lever)
Push the control lever upward in the “RES/ACC” direc-
tion and hold it until the vehicle reaches the desired
speed. Then, release the control lever. The vehicle
speed at that moment will be memorized and treated
as the new set speed.
When the difference between the actual vehicle speed
and the set speed is less than 4 mph (6.8 km/h), the
set speed can be increased 1 mph (1.6 km/h) each
time by pressing the control lever upward in the “RES/
ACC” direction quickly within 0.25 second. T
To increase the speed (by accelerator pedal)
1. Depress the accelerator pedal to accelerate the ve-
hicle to the desired speed.
2. Push the control lever downward in the “SET/
COAST” direction once. Now the desired speed is set
and the vehicle will keep running at that speed without
depressing the accelerator pedal.
NOTE
If the difference between the actual vehicle speed
when the control lever is pushed downward and
the speed last time you set it is less than 4 mph
(6.8 km/h), the vehicle speed will be lowered by 1
mph (1.6 km/h). This occurs because the cruise
control system unit regards this lever operation as
that intended to decrease the vehicle speed.

TTo decrease the speed (by control lever)
Push the control lever downward in the “SET/COAST”
direction and hold it until the vehicle reaches the de-
sired speed. Then, release the control lever. The vehi-
cle speed at that moment will be memorized and treat-
ed as the new set speed.
When the difference between the actual vehicle speed
and the set speed is less than 4 mph (6.8 km/h), the
set speed can be lowered 1 mph (1.6 km/h) each time
by pressing the control lever downward in the “SET/
COAST” direction quickly within 0.25 second. T
To decrease the speed (by brake pedal)
1. Depress the brake pedal to release cruise control
temporarily.
2. When the speed decreases to the desired speed,
press the control lever downward in the “SET/COAST”
direction once. Now the desired speed is set and the
vehicle will keep running at that speed without de-
pressing the accelerator pedal.

Driving tips
Driving tipsNew vehicle break-in driving – the
first 1,000 miles (1,600 km)
The performance and long life of your vehicle are de-
pendent on how you handle and care for your vehicle
while it is new. Follow these instructions during the
first 1,000 miles (1,600 km):y
Do not race the engine. And do not allow engine
speed to exceed 4,000 rpm except in an emergency.y Do not drive at one constant engine or vehicle
speed for a long time, either fast or slow. y Avoid starting suddenly and rapid acceleration, ex-
cept in an emergency. y Avoid hard braking, except in an emergency.
The same break-in procedures should be applied to
an overhauled engine, newly mounted engine or when
brake pads or brake linings are replaced with new
ones.
Fuel economy hints
The following suggestions will help to save your fuel. y Select the proper gear position for the speed and
road conditions. y Avoid sudden acceleration or deceleration. Always
accelerate gently until you reach the desired speed.
Then try to maintain that speed for as long as possible. y Do not pump the accelerator and avoid racing the
engine. y Avoid unnecessary engine idling.
y Keep the engine properly tuned.
y Keep the tires inflated to the correct pressure shown
on the tire placard, which is located under the door
latch on the driver’s side. Low pressure will increase
tire wear and fuel consumption.y Use the air conditioner only when necessary.
y Keep the front and rear wheels in proper alignment.
y Avoid carrying unnecessary luggage or cargo.

Engine exhaust gas (Carbon monox-
ide)
yNever inhale engine exhaust gas. Engine ex-
haust gas contains carbon monoxide, a color-
less and odorless gas which is dangerous, or
even lethal, if inhaled.y Always properly maintain the engine exhaust
system to prevent engine exhaust gas from en-
tering the vehicle.y Never run the engine in a closed space, such
as a garage, except for the brief time needed to
drive the vehicle in or out of it.y Avoid remaining in a parked vehicle for a
lengthy time while the engine is running. If that
is unavoidable, then use the ventilation fan to
force fresh air into the vehicle. y Always keep the front ventilator inlet grille
free from snow, leaves or other obstructions to
ensure that the ventilation system always
works properly. y If at any time you suspect that exhaust fumes
are entering the vehicle, have the problem
checked and corrected as soon as possible. If
you must drive under these conditions, drive only with all windows fully open.y
Keep the trunk lid or rear gate closed while
driving to prevent exhaust gas from entering
the vehicle.
NOTE
Due to the expansion and contraction of the met-
als used in the manufacture of the exhaust sys-
tem, you may hear a crackling sound coming from
the exhaust system for a short time after the en-
gine has been shut off. This sound is normal.
