engine Acura TL 2007 Owner's Guide

When slowing down, you can get
extra braking from the engine by
shifting to a lower gear. This extra
braking can help you maintain a safe
speed and prevent your brakes from
overheating while going down a
steep hill. Before downshifting,
make sure the engine speed will not
go into the tachometer’s red zone in
the lower gear.
The manual transmission is
synchronized in all forward gears for
smooth operation. It has a lockout so
you cannot accidentally shift from
f if th to reverse instead of sixth (see
page ). When shif ting up or
down,makesureyoupushtheclutch
pedal down all the way, shift to the
next gear, and let the pedal up
gradually. When you are not shif ting,
do not rest your f oot on the clutch
pedal. This can cause your clutch to
wear out faster. Come to a full stop before you shift
into reverse. You can damage the
transmission by trying to shif t into
reverse with the vehicle moving.
Push down the clutch pedal, and
pause f or a f ew seconds bef ore
shif ting into reverse, or shif t into one
of the f orward gears f or a moment.
This stops the gears so they won’t
‘‘grind.’’
251The engine can be damaged if
you inadvertently downshif t into the wrong gear (f or example, going f romthird gear at high rpms to second gearinstead of upshif ting to f ourth gear; theengine speed limiter will not work in thissituation).

Note:
Rapid slowing or speeding-up
can cause loss of control on
slippery surfaces. If you crash,
you can be injured.
Use extra care when driving on
slippery surfaces.

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.

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 the
ACCESSORY (I) or LOCK (0)
position.
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 dealer.

µ To
avoid transmission damage, come
to a complete stop before shifting
into Park. The shift lever must be in
Park before you can remove the key
from the ignition switch.
Use this position for
your normal driving. The transmis-
sion automatically adjusts to keep
the engine at the best speed for the
driving conditions.
ForfasteraccelerationwheninD,
you can get the transmission to
automatically downshift by pushing
the accelerator pedal to the floor.
The transmission will shift down one,
two or three gears, depending on
your speed.
Press
the brake
pedal to shift from Park to reverse.
To shift from neutral to reverse,
come to a complete stop and then
shift.
Your vehicle has a reverse lockout so
you cannot accidentally shift to
reverse from neutral or any other
driving position when the vehicle
speed exceeds 5 6 mph (8 10
km/h).
If you cannot shift to reverse when
the vehicle is stopped, press the
brake pedal, slowly shift to neutral,
andthenshifttoreverse.
If there is a problem in the reverse
lockout system, or your vehicle’s battery
is disconnected or goes dead,
you cannot shift to reverse. (Refer to
on page ).
Use neutral if you
need to restart a stalled engine, or if
it is necessary to stop briefly with
the engine idling. Shift to the Park
position if you need to leave your
vehicle and apply the parking brake.
Press on the brake pedal when you
are moving the shift lever from
neutral to another gear.
This position mechani-
cally locks the transmission. Use
Park whenever you are turning off or
starting the engine. To shift out of
Park, you must press on the brake
pedal and have your foot off the
accelerator pedal.
If you have done all of the above and
still cannot move the lever out of
Park, see on

µWhen you move the shif t lever f rom
‘‘D’’ to the Sequential SportShift
mode, the display shows the selected
gear.
With the shif t lever in ‘‘D’’ position,
you can select the Sequential
SportShift mode to shift 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 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 56 mph
(90 km/h), and f irst gear at about 29
mph (47 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. On Type-S, at
closed throttle, it selects second gear
at about 61 mph (98 km/h), and first
gear at about 37 mph (59 km/h).

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.
In Sequential SportShif t mode, you
can also shif t up or down by using

Make sure you upshif t bef ore the

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

To release the reverse lockout, make
sure the ignition switch is in the
ACCESSORY(I) position.Make sure the ignition switch is in
the LOCK (0) position. Set the parking brake.
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. 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

rpm below the red zone.
When you are in Sequential

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

Check the brakes after driving
through deep water. Apply the
brakes moderate ly to see if they feel
normal. If not, apply them gently and
frequently until they do. Be extra
cautious in your driving.
Your
vehicle is equipped with disc
brakes at all four wheels. A power
assist helps reduce the effort needed
on the brake pedal. The anti-lock
brake system (ABS) helps you retain
steering control when braking very
hard.
Constant application of the brakes
when going down a long hill builds
up heat and reduces their effective-
ness. Use the engine to assist the
brakes by taking your foot off the
accelerator and downshifting to a
lower gear.
Resting
your foot on the brake pedal
applies the brakes slightly. This
builds up heat, and reduces brake
effectiveness and brake pad life. In
addition, fuel economy can be
reduced. It also keeps your brake
lights on all the time, confusing
drivers behind you. The
hydraulic system that operates
the brakes has two separate circuits.
Each circuit works diagonally across
the vehicle (the left-front brake is
connected with the right-rear brake,
etc.). If one circuit should develop a
problem, you will still have braking
at two wheels, but the brake pedal
may not f eel normal (see page f or more inf ormation). 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 and braking
ef f ectiveness could be reduced. It is
normal for the brakes to occasionally
squeal or squeak when you apply
them.
