Starting and Operating
New Vehicle Break-In
Caution
Follow these recommended
guidelines during the first
2 414 km (1,500 mi) of driving this
vehicle. Parts have a break-in period
and performance will be better in
the long run.
.Avoid full throttle starts and
abrupt stops.
.Do not exceed 4000 engine rpm.
.Avoid driving at any one
constant speed, fast or slow.
.Do not drive above
129 km/h (80 mph).
.Avoid downshifting to brake or
slow the vehicle when the engine
speed will exceed 4000 rpm.
.Do not let the engine labor.
Never lug the engine in high gear
at low speeds. With a manual
transmission, shift to the next (Continued)
Caution (Continued)
lower gear. This rule applies at all
times, not just during the
break-in period.
.Do not participate in racing
events, sport driving schools,
or similar activities during this
break-in period.
.Check engine oil with every
refueling and add if necessary.
Oil and fuel consumption may be
higher than normal during the
first 2 414 km (1,500 mi).
.To break in new tires, drive at
moderate speeds and avoid hard
cornering for the first
322 km (200 mi). New tires do
not have maximum traction and
may tend to slip.
.New brake linings also need a
break-in period. Avoid making
hard stops during the first
322 km (200 mi). This is
recommended every time brake
linings are replaced.(Continued)

N :In this position, the engine does
not connect with the wheels. To
restart the engine when the vehicle is
already moving, use N (Neutral) only.
{Warning
Shifting into a drive gear while the
engine is running at high speed is
dangerous. Unless your foot is
firmly on the brake pedal, the
vehicle could move very rapidly.
You could lose control and hit
people or objects. Do not shift into
a drive gear while the engine is
running at high speed.
Caution
Shifting out of P (Park) or
N (Neutral) with the engine running
at high speed may damage the
transmission. The repairs would not
be covered by the vehicle warranty.
Be sure the engine is not running at
high speed when shifting the
vehicle.
Caution
A transmission hot message may
display if the automatic
transmission fluid is too hot.
Driving under this condition can
damage the vehicle. Stop and idle
the engine to cool the automatic
transmission fluid. This message
clears when the transmission fluid
has cooled sufficiently.

The transmission will only allow you
to shift into gears appropriate for the
vehicle speed and engine revolutions
per minute (rpm). The transmission
will not automatically shift to the next lower gear if the engine rpm is too
high, nor to the next higher gear when
the maximum engine rpm is reached.
If shifting is prevented for any reason,
a SHIFT DENIED message will be
displayed in the instrument cluster.
When accelerating the vehicle from a
stop in snowy and icy conditions, it is
suggested to shift into second gear.
A higher gear allows the vehicle to
gain more traction on slippery
surfaces.
