6. Check the adjustment of the insideand outside mirrors (see page
177).
7. Check the steering wheel adjustment (see page 145).
8. Make sure the doors and tailgate are securely closed and locked.
9. Fasten your seat belt. Check that your passengers have fastened
their seat belts (see page 16).
10. When you start the engine, check the gauges and indicators in the
instrument panel, and the
messages on the multi-information
display (see pages 63, 76 and 90). Starting the Engine
Your vehicle's starting system has an
auto control mode. When you turn
the ignition switch to the START (III)
position, this feature keeps the
engine's starter motor running until
the engine starts. Follow these
instructions to start the engine:
1. Apply the parking brake.
2. In cold weather, turn off all
electrical accessories to reduce the
drain on the battery.
3. Make sure the shift lever is in Park. Press on the brake pedal.
4. Without touching the accelerator pedal, turn the ignition switch to
the START (III) position, then
release the ignition switch. You do
not need to hold the ignition
switch in the START (III) position
to start the engine. The starter
motor can run for up to 9 seconds
to guarantee starting when the
outside temperature is very low. If you hold the ignition switch in
the START (III) position for more
than 7 seconds, the starter motor,
depending on the outside
temperature, runs for up to 25
seconds until the engine starts.
If the engine does not start, wait at
least 10 seconds before trying
again.
The immobilizer system protects your
vehicle from theft. If an improperly-
coded key (or other device) is used, the
engine's fuel system is disabled. For
more information, see page 149.

The engine is harder to start in cold
weather. Also, the thinner air found at
altitudes above 8,000 feet (2,400
meters) adds to this problem.Check Starting System Message
If there is a problem with the starting
system, you will see a
‘‘CHECK
STARTING SYSTEM ’’message on
the multi-information display when
the ignition switch is turned to the
ON (II) position. You will also see
this message when the auto control
mode of the starting system has a
problem. If this message is on, the ignition
switch has to be held in the START
(III) position manually until the
engine starts. The ignition switch can
be held in that position up to 15
seconds.
Even though you may be able to start
the engine manually without the auto
control mode of the starting system,
have your dealer inspect your
vehicle.

Check Starting System MessageIf there is a problem with the starting
system, you will see a‘‘CHECK
STARTING SYSTEM ’’message on
the multi-information display with the
power mode ON.
You will also see this message when
the auto control mode of the starting
system has a problem. If this message is on, you should
press and hold the engine start/stop
button until the engine starts. The
engine start/stop button can be
pressed up to 15 seconds.
Even though you may be able to start
the engine manually without the auto
control mode of the starting system,
have your vehicle inspected by a
dealer.
Your vehicle has the engine start/
stop button instead of an ignition
switch to select the power mode. For
more information, see page 194.
Emergency Engine Start
If you cannot start the engine using
the normal engine start procedure,
do the following:
1. Set the parking brake.
2. Put the shift lever into Park.
3. Press the engine start/stop button
to turn on the ACCESSORY mode.
4. Press and hold the engine start/ stop button for about 15 seconds
while pressing the brake pedal.
Do not follow this procedure unless it
is a case of emergency. Even if you
can start the engine using this
method, the system may have a
malfunction. Contact your dealer as
soon as possible.Starting the Engine (Models with Keyless Access System)47609/10/28 17:15:37 10 ACURA ZDX KA KC New North America Own 50 31SZN600 enu

Shift Lever Position IndicatorsThese indicators between the
tachometer and speedometer show
which position the shift lever is in.
Using a paddle shift mode, the gear
position indicator shows you the
selected gear number (see page
482).
The‘‘D ’’indicator comes on for a few
seconds when you turn the ignition
switch to the ON (II) position. If it
flashes while driving (in any shift
position), it indicates a possible
problem in the transmission. Models equipped with the keyless
access system have an engine start/
stop button instead of an ignition
switch. ON mode is the equivalent of
ON (II). See page 196 for ignition
switch and power mode comparison.
If the malfunction indicator lamp
comes on along with the
‘‘D ’’
indicator, there is a problem with the
automatic transmission control
system. Avoid rapid acceleration, and
have the transmission checked by
your dealer as soon as possible.
When the ‘‘D ’’indicator warns of a
possible problem with the
transmission, you will see a ‘‘CHECK
TRANSMISSION ’’message on the
multi-information display (see page
91).

3. Put a cloth on the edge of the shiftlock release slot cover to prevent
scratches. Use a small flat-tip
screwdriver or metal fingernail file
to carefully pry up the edge of the
cover and remove it from the slot.
4. Insert a key into the shift lockrelease slot.
5. Push down on the key or built-in key while you press the release
button on the front of the shift
lever and move the shift lever out
of Park to neutral. 6. Remove the key or built-in key
from the shift lock release slot,
then reinstall the cover. Make sure
the notch on the cover is on the
rear side. Press the brake pedal,
and restart the engine.
If you need to use the shift lock
release, it means your vehicle is
developing a problem. Have the
vehicle checked by a dealer.

If the SH-AWD indicator blinks while
driving, it indicates the differential
temperature is too high. You will also
see an‘‘SH-AWD DIFF TEMP.
HIGH ’’message on the multi-
information display. If this happens,
pull to the side of the road when it is
safe, shift to Park, and let the engine
idle until the indicator goes out. If
the indicator does not go out, take
your vehicle to a dealer to have it
checked.
If the SH-AWD indicator on the
instrument panel stays on, and the
‘‘ CHECK SH-AWD SYSTEM ’’
message also appears on the multi-
information display, there is problem
with the SH-AWD system. Your vehicle still has normal front-
wheel drive with vehicle stability
assist (VSA), but does not have the
advantages of SH-AWD. Have your
vehicle checked by a dealer as soon
as possible.

Your vehicle is equipped with a tire
pressure monitoring system (TPMS)
that turns on every time you start the
engine and monitors the pressure in
your tires while driving.
Each tire has its own pressure
sensor. If the air pressure of a tire
becomes significantly low, the sensor
in that tire immediately sends a
signal that causes the low tire
pressure/TPMS indicator in the
instrument panel to come on. If this
happens, you will see which tire is
losing pressure on the multi-
information display along with a
‘‘CHECK TIRE PRESSURE ’’
message.
Low Tire Pressure/
TPMS Indicator
When the low tire pressure/TPMS
indicator is on, one or more of your
tires is significantly underinflated.
You should stop and check your tires
as soon as possible, and inflate them
to the proper pressure as indicated
on the vehicle's tire information
placard.
It is possible that the pressures
shown on the multi-information
display and the pressures you
manually measure are slightly
different.
If the difference is significant or you
cannot make the low tire pressure/
TPMS indicator and message on the
multi-information display go out after
inflating the tires to the specified
values, have your dealer check the
system as soon as possible. If you think you can safely drive a
short distance to a service station,
proceed slowly to the station, then
inflate the tire to the recommended
pressure.
If the tire is flat, or if the tire pressure
is too low to continue driving, replace
the tire with the compact spare tire
(see page 579).
Driving on a significantly under-
inflated tire causes the tire to
overheat and can lead to tire failure.
Under-inflation also reduces fuel
efficiency and tire tread life, and may
affect the vehicle's handling and
stopping ability.
Because tire pressure varies by
temperature and other conditions,
the low tire pressure/TPMS
indicator may come on unexpectedly.
Tire Pressure Monitoring System (TPMS)49009/10/28 17:15:37 10 ACURA ZDX KA KC New North America Own 50 31SZN600 enu

Each tire pressure is shown in PSI
(U.S. models) or in kPa (Canadian
models).
Models equipped with the keyless
access system have an engine start/
stop button instead of an ignition
switch. ON mode is the equivalent of
ON (II). See page 196 for ignition
switch and power mode comparison.
Each tire has its own pressure
sensor. If the air pressure of a tire
becomes significantly low, the sensor
in that tire immediately sends a
signal that causes the low tire
pressure/TPMS indicator in the
instrument panel to come on. If this
happens, you will see which tire is
losing pressure on the multi-
information display along with a
‘‘CHECK TIRE PRESSURE ’’
message.
If any of the tires has low pressure,
the tire pressure monitor also shows
the above message and each tire
pressure to warn you about the low
tire pressure when you select the
display by pressing the INFO button
several times.

Your vehicle is equipped with disc
brakes at all four wheels. A power
assist helps reduce the effort needed
on the brake pedal. The emergency
brake assist system increases the
stopping force when you depress the
brake pedal hard in an emergency
situation. The anti-lock brake system
(ABS) helps you retain steering
control when braking very hard.
Resting your foot on the pedal keeps
the brakes applied lightly, builds up
heat, and reduces their effectiveness
and reduces brake pad life. In
addition, fuel economy can be
reduced. It also keeps your brake
lights on all the time, confusing
drivers behind you.Constant application of the brakes
when going down a long hill builds
up heat and reduces their
effectiveness. Use the engine to
assist the brakes by taking your foot
off the accelerator and downshifting
to a lower gear.
Check the brakes after driving
through deep water. Apply the
brakes moderately to see if they feel
normal. If not, apply them gently and
frequently until they do. Be extra
cautious in your driving.
Braking System Design
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.
Brake Wear Indicators
All four brakes have audible brake
wear indicators.
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 for
the brakes to occasionally squeal or
squeak when you apply them.
