To jump start your vehicle, f ollow
these directions closely:
If your vehicle’s battery has run
down,youmaybeabletostartthe
engine by using a booster battery.
Although this seems like a simple
procedure, you should take several
precautions.
Put the transmission in Neutral or
Park, and set the parking brake. Open the hood and check the
physical condition of the battery
(see page ). In very cold
weather, check the condition of
the electrolyte. If it seems slushy
or like ice, do not try jump starting
until it thaws.
Turn of f all the electrical acces-
sories: heater, A/C, climate
control, stereo system, lights, etc.
You cannot start your Acura by
pushing or pulling it.
Your vehicle has the Immobilizer
System. You should use a
properly-coded master or valet key
to start the engine (see page ).
A key that is not properly coded
will cause the immobilizer system
indicator in the dash panel to blink
rapidly.
Do you have f uel? Turn the
ignition switch to ON (II) for a
minute and watch the f uel gauge.
The low f uel level warning light
may not be working, so you were
not reminded to f ill the tank.
There may be an electrical
problem, such as no power to the
f uel pump. Check all the f uses
(see page ).
If youfindnothingwrong,youwill
need a qualif ied technician to f ind
the problem. See on page . 1.

T aking Care of t he Unexpect ed369
A battery can explode if you do
not follow the correct procedure,
seriously injuring anyone
nearby.
Keep all sparks, open flames,
and smoking materials away
from the battery. If a battery sits in extreme cold, the
electrolyte inside can f reeze.
Attempting to jump start with a f rozen
battery can cause it to rupture.

If you see steam and/or spray
coming f rom under the hood, turn
of f the engine.
If you do not see steam or spray,
leave the engine running and
watch the temperature gauge. If
the high heat is due to overloading
(climbing a long, steep hill on a
hot day with the A/C running, for
example), the engine should start
to cool down almost immediately.
If it does, wait until the tempera-
ture gauge comes down to the mid-
point then continue driving. Saf ely pull to the side of the road.
Put the transmission in Neutral or
Park and set the parking brake.
Turn of f the heating and cooling/
climate control system and all
otheraccessories.Turnonthe
hazard warning indicators.
Keep the ends of the jumper cables
away from each other and any metal
on the vehicle until all are
disconnected. Otherwise, you may
cause an electrical short.
The pointer of your vehicle’s
temperature gauge should stay in
the midrange under most conditions.
Itmaygohigherif youaredrivingup
a long steep hill on a very hot day. If
it climbs to the red mark, you should
determine the reason. Your vehicle can overheat for several
reasons, such as lack of coolant or a
mechanical problem. The only
indication may be the temperature
gauge climbing to or above the red
mark. Or you may see steam or
spray coming f rom under the hood.
In either case, you should take
immediate action.

Steam and spray from an
overheated engine can
seriously scald you.
Do not open the hood if steam
is coming out.
Driving with the temperature gauge
pointer at the red mark can cause
serious damage to your engine.

However, if the brake pedal does not
f eel normal, you should take
immediate action. Because of the
brake system’s dual-circuit design, a
problem in one part of the system
will still give you braking at two
wheels. You will f eel the brake pedal
go down much f arther bef ore the
vehicle begins to slow down, and you
will have to press harder on the
pedal. The distance needed to stop
will be much longer. If it comes on at any other time, it
indicates a problem with the vehicle’s
brake system. In most cases, the
problem is a low f luid level in the
brake f luid reservoir. Press lightly on
the brake pedal to see if it f eels
normal. If it does, check the brake
f luid level the next time you stop at a
service station (see page ). If the
f luid level is low, take the vehicle to
your dealer and have the brake
system inspected f or leaks or worn
brake pads.Slow down by shif ting to a lower
gear, and pull to the side of the road
when it is saf e. Because of the
longer distance needed to stop, it is
hazardous to drive the vehicle. You
should have it towed, and repaired as
soon as possible. (See
on page .)
If you must drive the vehicle a short
distance in this condition, drive
slowly and cautiously.
The Brake System Indicator comes
on when you turn the ignition ON
(II). If the parking brake is not set, it
goes of f af ter you start the engine. If
the parking brake is set, it goes of f
when you f ully release the parking
brake with the engine running. 319
