Starting the engine
1. Make sure the parking brake is
applied.
2. Make sure the shift lever is in P
(Park).
3. Depress the brake pedal.
4. Turn the ignition switch to the
START position. Hold the key
(maximum of 10 seconds) until the
engine starts and release it.
Information
• It is best to maintain a moderate
engine speed until the vehicle engine
comes up to normal operating tem-
perature. Avoid harsh or abrupt
acceleration or deceleration while
the engine is still cold.
• Whether the engine is cold or warm,
always start the vehicle with your
foot on the brake pedal. Do not
depress the accelerator while start-
ing the vehicle. Do not race the
engine while warming it up.To prevent damage to the vehicle:
Do not hold the ignition key in
the START position for more
than 10 seconds. Wait 5 to 10
seconds before trying again.
Do not push or tow your vehicle
to start the engine.
NOTICEi
Driving your vehicle
Always wear appropriate shoes
when operating your vehicle.
Unsuitable shoes, such as high
heels, ski boots, sandals, flip-
flops, etc., may interfere with
your ability to use the brake and
accelerator pedals.
WARNING

5-19
Driving your vehicle
Parking
Always come to a complete stop and
continue to depress the brake pedal.
Move the shift lever into the P (Park)
position, apply the parking brake,
and place the ignition switch in the
LOCK/OFF position. Take the Key
with you when exiting the vehicle.
Good Driving Practices
Never move the shift lever from P
(Park) or N (Neutral) to any other
position with the accelerator pedal
depressed.
Never move the shift lever into P
(Park) when the vehicle is in
motion.
Be sure the vehicle is completely
stopped before you attempt to shift
into R (Reverse) or D (Drive).
Do not move the shift lever to N
(Neutral) when driving. Doing so
may result in an accident because
of a loss of engine braking and the
transmission could be damaged.
Do not drive with your foot resting
on the brake pedal. Even light, but
consistent pedal pressure can
result in the brakes overheating,
brake wear and possibly even
brake failure.
Depressing both accelerator and
brake pedals at the same time can
trigger logic for engine power
reduction to assure vehicle decel-
eration. Vehicle acceleration will
resume after the brake pedal is
released. When driving in Manual Shift
Mode, slow down before shifting to
a lower gear. Otherwise, the lower
gear may not be engaged if the
engine rpms are outside of the
allowable range.
Always apply the parking brake
when leaving the vehicle. Do not
depend on placing the transmis-
sion in P (Park) to keep the vehicle
from moving.
Exercise extreme caution when
driving on a slippery surface. Be
especially careful when braking,
accelerating or shifting gears. On a
slippery surface, an abrupt change
in vehicle speed can cause the
drive wheels to lose traction and
may cause loss of vehicle control
resulting in an accident.
Optimum vehicle performance and
economy is obtained by smoothly
depressing and releasing the
accelerator.
5
When you stay in the vehicle
with the engine running, be
careful not to depress the
accelerator pedal for a long
period of time. The engine or
exhaust system may overheat
and start a fire.
The exhaust gas and the
exhaust system are very hot.
Keep away from the exhaust
system components.
Do not stop or park over flam-
mable materials, such as dry
grass, paper or leaves. They
may ignite and cause a fire.
WARNING

5-26
Driving your vehicle
EPB (Electronic Parking Brake)
may be automatically applied
when:
Requested by other systems
The driver turns the engine off
while Auto Hold is operating.
Warning messages
To release EPB, fasten seatbelt,
close door, hood and liftgate
If you try to drive with the EPB
applied, a warning will sound and a
message will appear.
If the driver's seat belt is unfas-
tened and the engine hood or lift-
gate is opened, a warning will
sound and a message will appear.
If there is a problem with the vehi-
cle, a warning may sound and a
message may appear.
If the situation occurs, depress the
brake pedal and release EPB by
pressing the EPB switch.
OTMA058132
Whenever leaving the vehicle
or parking, always come to a
complete stop and continue
to depress the brake pedal.
Move the shift lever into the P
(Park) position, press the EPB
switch, and set the ignition
switch to the OFF position.
Take the Key with you when
exiting the vehicle.
Vehicles not fully engaged in
P (Park) with the parking
brake set are at risk for mov-
ing inadvertently and causing
injury to yourself or others.
NEVER allow anyone who is
unfamiliar with the vehicle to
touch the EPB switch. If the
EPB is released unintentional-
ly, serious injury may occur.
Only release the EPB when
you are seated inside the
vehicle with your foot firmly
on the brake pedal.
