To prevent accelerated battery discharge and a possible
dead battery, always remove the key from the steering
lock. Do not leave the key in steering lock position 0.
Notes:
A warning sounds when the driver’s door is opened

With the engine at idle speed, the charging rate of the
alternator (output) is limited.It is therefore recommended that you turn off
unnecessary electrical consumers while driving in stop-
and-go traffic. This precaution helps to avoid draining of
the battery.
Unnecessary strain on the battery and charging system
may be minimized by turning off the following power
consumers, for example: Heated seats, rear window
defroster.

Caution!
Do not remove head restraints except when mounting
seat covers. For removal see page 43. Whenever head
restraints have been removed be sure to reinstall them
before driving.
Wa r n i n g !
Do not adjust the driver’s seat while driving.
Adjusting the seat while driving could cause the
driver to lose control of the vehicle.Never ride in a moving vehicle with the backrest
reclined. Sitting in an excessively reclined position
can be dangerous. You could slide under the seat
belt in a collision. If you slide under it, the belt
would apply force at the abdomen or neck. That
could cause serious or even fatal injuries. The
backrest and seat belt provide the best restraint
when the wearer is in an upright position and the
belt is properly positioned on the body.Never place hands under seat or near any moving
parts while a seat is being adjusted.
Wa r n i n g !
When leaving the vehicle always remove the key
from the steering lock, and lock your vehicle.Do not leave children unattended in the vehicle or
with access to an unlocked vehicle. Unsupervised
use of vehicle equipment may cause serious
personal injury.
