If you have a flat tire while driving,
stop in a safe place to change it.
Drive slowly along the shoulder until
you get to an exit or an area to stop
that is far away from the traffic lanes.
The vehicle can easily roll off
the jack, seriously injuring
anyone underneath.
Follow the directions for
changing a tire exactly, and
never get under the vehicle
when it is supported only by the
jack.
1. Park the vehicle on firm, level, and non-slippery ground. Put the
transmission in Park. Apply the
parking brake.
2. Turn on the hazard warning lights,and turn the ignition switch to the
LOCK (0) position. Have all
passengers get out of the vehicle
while you change the tire.
3. Open the tailgate. 4. Push the rear edge of the handle
to raise the handle loop and pull up
the loop to raise the cargo area
floor.

12. Place the jack under the jackingpoint nearest the tire you need to
change. Turn the end bracket
clockwise until the top of the jack
contacts the jacking point. Make
sure the jacking point tab is
resting in the jack notch.
13. Use the extension and the wheelnut wrench as shown to raise the
vehicle until the flat tire is off the
ground.
14. Remove the wheel nuts, then remove the flat tire.
15. Before mounting the spare tire,wipe any dirt off the mounting
surface of the wheel and hub with
a clean cloth. Wipe the hub
carefully; it may be hot from
driving.

●
Are you using the proper starting
procedure? Refer toStarting the
Engine on page 436.
●
Do you have fuel? Check the fuel
gauge; the warning indicator may
not be working.
●
There may be an electrical
problem, such as no power to the
fuel pump. Check all the fuses (see
page 560).
If you find nothing wrong, you will
need a qualified technician to find the
problem. See Emergency Towing on
page 566. Jump Starting
Although this seems like a simple
procedure, you should take several
precautions.
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.
You cannot start your vehicle by
pushing or pulling it.
To Jump Start Your Vehicle:1. Open the hood, and check the physical condition of the battery.
In very cold weather, check the
condition of the electrolyte. If it
seems slushy or frozen, do not try
jump starting until it thaws.If a battery sits in extreme cold, the
electrolyte inside can freeze. Attempting
to jump start with a frozen battery can
cause it to rupture.
2. Turn off all the electricalaccessories: heater, A/C, climate
control, audio system, lights, etc.
Put the transmission in neutral or
Park, and set the parking brake.
If the Engine Won't Start, Jump Starting55210/06/29 11:59:04 11 ACURA MDX MMC North America Owner's M 50 31STX640 enu

The pointer of your vehicle's
temperature gauge should stay in the
midrange under most conditions. If it
climbs to the red mark, you should
determine the reason (hot day,
driving up a steep hill, etc.).
If the vehicle overheats, you should
take immediate action. The only
indication may be the temperature
gauge climbing to or above the red
mark. Or you may see steam or spray
coming from under the hood.Driving with the temperature gauge
pointer at the red mark can cause
serious damage to the engine.
Steam and spray from an
overheated engine can
seriously scald you.
Do not open the hood if steam
is coming out.1. Safely pull to the side of the road.
Put the transmission in Park, and
set the parking brake. Turn off all
accessories, and turn on the
hazard warning indicators.
2. If you see steam and/or spray coming from under the hood, turn
off the engine. Wait until you see
no more signs of steam or spray,
then open the hood.
3. 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, the engine should
start to cool down almost
immediately. If it does, wait until
the temperature gauge comes
down to the midpoint, then
continue driving.
If the Engine Overheats55410/06/29 11:59:04 11 ACURA MDX MMC North America Owner's M 50 31STX640 enu

U.S. Canada
The brake system
indicator normally
comes on when you turn the ignition
switch to the ON (II) position, and as
a reminder to check the parking
brake. It will stay on if you do not
fully release the parking brake.
If the brake system indicator comes
on while driving, the brake fluid level
is probably low. Press lightly on the
brake pedal to see if it feels normal. If
it does, check the brake fluid level
the next time you stop at a service
station (see page 519).
You will also see a ‘‘LOW BRAKE
FLUID ’’message on the multi-
information display (see page 86). If the fluid level is low, take your
vehicle to a dealer, and have the
brake system inspected for leaks or
worn brake pads.
However, if the brake pedal does not
feel normal, you should take
immediate action. A problem in one
part of the system's dual circuit
design will still give you braking at
two wheels. You will feel the brake
pedal go down much farther before
the vehicle begins to slow down, and
you will have to press harder on the
pedal.
You will also see a
‘‘CHECK BRAKE
SYSTEM ’’message on the multi-
information display (see page 86). Slow down by shifting to a lower
gear, and pull to the side of the road
when it is safe. Because of the long
distance needed to stop, it is
hazardous to drive the vehicle. You
should have it towed, and repaired as
soon as possible (see
Emergency
Towing on page 566).
If you must drive the vehicle a short
distance in this condition, drive
slowly and carefully.
If the ABS indicator and the VSA
system indicator come on with the
brake system indicator, have your
vehicle inspected by your dealer
immediately.

7. Select a nearby lightly traveledmajor highway where you can
maintain a speed of 50 to 60 mph
(80 to 97 km/h) for at least 20
minutes. Drive on the highway in
D. Do not use the cruise control.
When traffic allows, drive for 90
seconds without moving the
accelerator pedal. (Vehicle speed
may vary slightly; this is okay.) If
you cannot do this for a continuous
90 seconds because of traffic
conditions, drive for at least 30
seconds, then repeat it two more
times (for a total of 90 seconds). 8. Then drive in city/suburban traffic
for at least 10 minutes. When
traffic conditions allow, let the
vehicle coast for several seconds
without using the accelerator pedal
or the brake pedal. 9. Make sure the vehicle has been
parked with the engine off for 30
minutes.
If the testing facility determines the
readiness codes are still not set, see
your dealer.Emissions Testing58410/06/29 11:59:04 11 ACURA MDX MMC North America Owner's M 50 31STX640 enu
