2004 Acura TL engine

Drive in the highest gear that lets
the engine run and accelerate
smoothly. This will give you the best
f uel economy and ef f ective emis-
sions control. The f ollowing shif t
points are recommended:If you exceed the maximum speed
f or the gear you are in, the engine
speed will enter into the tachometer’s
red zone. If this occurs, you may f eel
the engine cut in and out. This is
caused by a limiter in the engine’s
computer controls. The engine will
run normally when you reduce the
RPM below the red zone.
Bef ore downshif ting, make sure the
engine will not go into the
tachometer’s red zone.

The 6-speed manual transmission
has an electric lockout so you cannot
accidentally shif t f rom Fif th to
Reverse instead of Sixth. If you
cannot shif t to Reverse when the
vehicle is stopped:With the clutch pedal pressed,
move the shift lever to the first/
second gear side of the Neutral
gate, then shif t to Reverse.If you are still unable to shif t to
Reverse, apply the parking brake
and turn the ignition key to
ACCESSORY (I) or LOCK (0).
Press the clutch pedal, and shif t to
Reverse.
With the clutch pedal still pressed,
start the engine.
If you need to use this procedure to
shif t to Reverse, your vehicle may be
developing a problem. Have the
vehicle checked by your Acura
dealer.

To avoid transmission damage, come
to a complete stop bef ore shif ting
into Park. The shif t lever must be in
Park bef ore you can remove the key
from the ignition switch.
Your vehicle has a reverse lockout so
you cannot accidentally shif t to
Reverse from Neutral or any other
driving position when the vehicle
speed exceeds 5 6 mph (8 10
km/h).
If you cannot shif t to Reverse when
the vehicle is stopped, press the
brake pedal and slowly shift to
Neutral, and then to Reverse.
If there is a problem in the reverse
lockout system, or your vehicle’s battery is disconnected or goes dead,
you cannot shif t to Reverse. (Ref er
to Shif t Lock Release on page ).
Use Neutral if you
need to restart a stalled engine, or if
it is necessary to stop brief ly with
the engine idling. Shif t to the Park
position if you need to leave your
vehicle for any reason. Press on the
brake pedal when you are moving
the shift lever from Neutral to
another gear.
Use this position f or
your normal driving. The transmis-
sion automatically selects a suitable
gear f or your speed and acceleration.
ForfasteraccelerationwheninD,
you can get the transmission to
automatically downshif t by pushing
the accelerator pedal to the floor.
The transmission will shif t down one,
two or three gears, depending on
your speed.
This position mechani-
cally locks the transmission. Use
Park whenever you are turning of f or
starting the engine. To shif t out of
Park, you must press on the brake
pedal and have your f oot of f the
accelerator pedal.
If you have done all of the above and
still cannot move the lever out of
Park, see on
page . Press the brake
pedal to shift from Park to Reverse.
To shift from Neutral to Reverse,
come to a complete stop and then
shif t.

µµ When you accelerate away f rom a
stop, the transmission will start in
first gear and then automatically
upshif t to second gear. You have to
manually upshif t between second
and f if th gears. Make sure you
upshif t bef ore the engine speed
reaches the tachometer’s red zone.
The transmission remains in the
selected gear (5, 4, 3). There is no
automatic downshif t when you push
the accelerator pedal to the floor.
When you move the
shif t lever to this position, the
transmission shifts to the lowest
gear that can be selected without
exceeding the engine redline. At
normal speeds, it selects third gear.
As the vehicle slows, it selects
second gear at about 53 mph
(85 km/h), and f irst gear at about 28
mph (45 km/h). Accelerating in f irst
gear, the transmission upshif ts to
second gear at about 37 mph
(59 km/h). You must move the shif t
lever to D f or the transmission to
upshif t to third gear.
In Sequential SportShif t mode, each
time you push f orward on the shif t
lever, the transmission shifts to a
higher gear. Pull back on the lever to
downshif t. The number of the gear
selected is displayed on the
instrument panel.
With
the shif t lever in ‘‘D’’ position, you
can select the Sequential SportShif t
Mode to shif t gears much like a
manual transmission, but without a
clutch pedal.
To enter the Sequential SportShif t
Mode, move the shif t lever f urther to
the driver’s side. To return to ‘‘D’’,
move the shift lever to the passenger’s side.
When you move the shif t lever f rom
‘‘D’’ to the Sequential SportShift
mode, the display shows the selected
gear.

The transmission may automatically
downshif t f rom the higher gear to
the lower gear under these
conditions:
Downshif ting gives you more power
when climbing, and provides engine
braking when going down a steep hill.
The transmission will also shif t
automatically as the vehicle comes to
a complete stop. It will downshif t to
f irst gear when the vehicle speed is
under 9 mph (15 km/h).
If you try to manually downshif t at a
speed that would cause the engine to
exceed the redline in a lower gear,
the transmission will not downshif t.If the vehicle speed slows to below
the redline of the selected lower gear
position while the indicator is
f lashing, the transmission will
downshif t and the display will show
the selected lower gear.
The table shows the speed ranges

Sportshif t mode, and the vehicle is
stopped, push f orward on the shif t
lever to shif t to second gear. You will
see ‘‘2’’ in the display. Starting out in
second gear will help to reduce
wheelspin in deep snow or on a
slippery surf ace.
If you exceed the maximum speed
f or the gear you are in, the engine
speed will enter into the tachometer’s
red zone. If this occurs, you may f eel
the engine cut in and out. This is
caused by a limiter in the engine’s
computer controls. The engine will
run normally when you reduce the
RPM below the red zone. This allows you to move the shif t
lever out of Park if the normal
method of pushing on the brake
pedal does not work. This procedure
is also used to release the Reverse
Lockout.
Set the Parking brake.
Make sure the ignition switch is in
the LOCK (0) position.
To release the Reverse Lockout,
make sure the ignition switch is in
the ACCESSORY (I) position.

Check the brakes after driving
through deep water. Apply the
brakes moderately to see if they f eel
normal. If not, apply them gently and
f requently until they do. Be extra
cautious in your driving.
The hydraulic system that operates
the brakes has two separate circuits.
Each circuit works diagonally across
the vehicle (the lef t-f ront brake is
connected with the right-rear brake,etc.). If one circuit should develop a
problem, you will still have braking
at two wheels.
Your Acura is equipped with disc
brakes at all f our wheels. A power
assist helps reduce the ef f ort needed
on the brake pedal. The ABS helps
you retain steering control when
braking very hard.
Resting your f oot on the pedal keeps
the brakes applied lightly, builds up
heat, and reduces their ef f ectiveness.
It also keeps your brake lights on all
the time, conf using drivers behind
you.
Constant application of the brakes
when going down a long hill builds
up heat and reduces their ef f ective-
ness. Use the engine to assist the
brakes by taking your f oot of f the
accelerator and downshif ting to a
lower gear. If the brake pads need replacing, you
will hear a distinctive, metallic
screeching sound when you apply
the brake pedal. If you do not have
the brake pads replaced, they will
screech all the time. It is normal f or
the brakes to occasionally squeal or
squeak when you apply them.
