Driving and Operating 9-21
Starting the Engine
Move the shift lever to P (Park) or
N (Neutral) for an automatic
transmission. For a manual
transmission the vehicle can be
started in Neutral or any other gear
as long as the clutch pedal is
pressed. To restart a vehicle with a
manual transmission when you are
already moving, use the Neutral
position only. To restart a vehicle
with an automatic transmission
when you are already moving, use
N (Neutral).
Notice:Do not try to shift to
P (Park) if the vehicle is moving.
If you do, you could damage the
transmission. Shift to P (Park)
only when the vehicle is stopped.
The RKE transmitter must be inside
the vehicle for the ignition to work. Cell phone chargers can interfere
with the operation of the Keyless
Access System. Battery chargers
should not be plugged in when
starting or turning off the engine.
To start the vehicle, do the following:
1. For vehicles with an automatic
transmission, with your foot on
the brake pedal, press the
START button located on the
instrument panel. For vehicles
with a manual transmission, you
must also press in the clutch
pedal while pressing the
START button.
If there is not an RKE transmitter
in the vehicle or if there is
something causing interference
with it, the DIC will display
NO FOBS DETECTED.
See Key and Lock Messages on
page 5‑43 for more information. 2. When the engine begins
cranking, let go of the button and
the engine cranks automatically
until it starts. If the battery in the
RKE transmitter is weak, the
DIC displays FOB BATTERY
LOW. You can still drive the
vehicle.
See “Battery Replacement”
under Remote Keyless Entry
(RKE) System Operation on
page 2‑3 for more information.
If the fob battery is dead, you
need to insert the fob into the
fob slot to enable engine
starting. See “NO FOBS
DETECTED” underKey and
Lock Messages on page 5‑43.
3. Do not race the engine immediately after starting it.
Operate the engine and
transmission gently until the oil
warms up and lubricates all
moving parts.

What to Add
Use only new DOT 3 brake fluid
from a sealed container. See
Recommended Fluids and
Lubricants on page 11‑12.
Always clean the brake fluid
reservoir cap and the area
around the cap before removing it.
This helps keep dirt from entering
the reservoir.
{WARNING
With the wrong kind of fluid in
the brake hydraulic system, the
brakes might not work well.
This could cause a crash.
Always use the proper brake fluid.Notice
.Using the wrong fluid can
badly damage brake
hydraulic system parts.
For example, just a few
drops of mineral-based oil,
such as engine oil, in the
brake hydraulic system can
damage brake hydraulic
system parts so badly that
they will have to be replaced.
Do not let someone put in
the wrong kind of fluid.
.If brake fluid is spilled on the
vehicle's painted surfaces,
the paint finish can be
damaged. Be careful not to
spill brake fluid on the
vehicle. If you do, wash it off
immediately.
Battery
Refer to the replacement number
on the original battery label when a
new battery is needed.
For battery replacement, see your
dealer or the service manual.
To purchase a service manual,
see
Service Publications Ordering
Information on page 13‑17.
{WARNING
Battery posts, terminals, and
related accessories contain lead
and lead compounds, chemicals
known to the State of California to
cause cancer and reproductive
harm. Wash hands after handling.
