Vehicle speeds above
110 km/h (68 mph) should
be limited to five minutes
per use.
.Avoid making hard stops
for the first 322 km (200 mi)
or so. During this time the
new brake linings are not
yet broken in. Hard stops
with new linings can mean
premature wear and earlier
replacement. Follow this
breaking-in guideline every
time you get new brake
linings.
.Do not tow a trailer during
break-in. SeeDriving
Characteristics and Towing
Tips on page 9‑56 for the
trailer towing capabilities
of your vehicle and more
information.
Following break‐in, engine
speed and load can be gradually
increased.
Ignition Positions
(Key Access)
The ignition switch has four different
positions.
Notice: Using a tool to force the
key to turn in the ignition could
cause damage to the switch or
break the key. Use the correct
key, make sure it is all the way in,
and turn it only with your hand.
If the key cannot be turned by
hand, see your dealer. The key must be fully extended to
start the vehicle.

to N (Neutral), firmly apply the
brakes and steer the vehicle to
a safe location.
3. Come to a complete stop, shift to P (Park), and turn the ignition

the shift lever must be in P (Park). C (ON/RUN):
The ignition
switch stays in this position
when the engine is running.

display some warning and indicator
lights. The transmission is also
unlocked in this position.
The battery could be drained if the
key is left in the ACC/ACCESSORY
or ON/RUN position with the engine
off. The vehicle might not restart if
the battery is allowed to drain for an
extended period of time.
