A driver’s attention to the road must always
be his/her primary focus when driving. For
your safety and the safety of others, we rec-
ommend that you pull over to a safe location
and stop before placing or taking a tele-
phone call. If you choose to use the tele-

ditions permit.
Some jurisdictions prohibit the driver from
using a cellular telephone while driving a ve-
hicle.

ment on select models and not available
on all models.
For information on driving with a manual
transmission, see “Manual transmission”
(page 48).
Warning!
G
For vehicles equipped with a manual trans-
mission, getting out of your vehicle with the
gearshift lever not engaged in first or re-
verse gear and parking brake engaged is
dangerous.
Also, when parked on an incline, an engaged
first or reverse gear alone may not prevent
your vehicle from moving, possibly hitting
people or objects.
Always set the parking brake in addition to
engaging first or reverse gear (
page 56).
When parked on an incline, turn front wheels
towards the road curb.
Do not park this vehicle in areas where com-
bustible materials such as grass, hay or
leaves can come into contact with the hot
exhaust system, as these materials could be
ignited and cause a vehicle fire.
Warning!
G
When leaving the vehicle, always remove the
SmartKey from the starter switch, take it
with you, and lock the vehicle. Do not leave
children unattended in the vehicle, or with
access to an unlocked vehicle. Children
could move the gearshift lever, which could
result in an accident and/or serious injury.Warning!
G
On slippery road surfaces, never downshift
in order to obtain braking action.
This could result in drive wheel slip and re-
duced vehicle control. Your vehicle’s ABS
will not prevent this type of loss of control.

152 Controls in detailAutomatic transmission*For more information on driving with an
automatic transmission, see “Automatic
transmission*” (
page 48).
Your vehicle’s transmission adapts its gear
shifting process to your individual driving
style by continually adjusting the shift
points up or down. These shift point adjust-
ments are performed based on current
operating and driving conditions.
If the operating conditions change, the
automatic transmission reacts by
adjusting its shift program.
Gearshift pattern for automatic
transmission
The automatic transmission selects indi-
vidual gears automatically, depending on:
the gear selector lever

gear ranges (page 155)

iDuring the brief warm-up, transmission
upshifting is delayed. This allows the
catalytic converter to heat up more
quickly to operating temperature.
