are entering the vehicle, have the problem
checked and corrected as soon as possible. If
you must drive under these conditions, drive
only with all windows fully open. "Keep the trunk lid or rear gate closed while
driving to prevent exhaust gas from entering
the vehicle.
! Drinking and driving
Drinking and then driving is very dangerous.
Alcohol in the bloodstream delays your reac-
tion and impairs your perception, judgment and
attentiveness. If you drive after drinking – even
if you drink just a little – it will increase the risk
of being involved in a serious or fatal accident,
injuring or killing yourself, your passengers
and others. In addition, if you are injured in the
accident, alcohol may increase the severity of
that injury.
Please don’t drink and drive.
Drunken driving is one of the most frequent causes of accidents. Since alcohol affects all people differently,
you may have consumed too much alcohol to drive
safely even if the level of alcohol in your blood is below
the legal limit. The safest thing you can do is never
drink and drive. However if you have no choice but to
drive, stop drinking and sober up completely before
getting behind the wheel. !
Drugs and driving
There are some drugs (over the counter and
prescription) that can delay your reaction time
and impair your perception, judgment and at-
tentiveness. If you drive after taking them, it
may increase your, your passengers’ and other
persons’ risk of being involved in a serious or
fatal accident.
If you are taking any drugs, check with your doctor or
pharmacist or read the literature that accompanies the
medication to determine if the drug you are taking can
impair your driving ability. Do not drive after taking any
medications that can make you drowsy or otherwise
affect your ability to safely operate a motor vehicle. If

10
you have a medical condition that requires you to take
drugs, please consult with your doctor.
Never drive if you are under the influence of any illicit
mind-altering drugs. For your own health and well-be-
ing, we urge you not to take illegal drugs in the first
place and to seek treatment if you are addicted to
those drugs. !Driving when tired or sleepy
When you are tired or sleepy, your reaction will
be delayed and your perception, judgment and
attentiveness will be impaired. If you drive
when tired or sleepy, your, your passengers’
and other persons’ chances of being involved
in a serious accident may increase.
Please do not continue to drive but instead find a safe
place to rest if you are tired or sleepy. On long trips,
you should make periodic rest stops to refresh your-
self before continuing on your journey. When possible,
you should share the driving with others. !
Modification of your vehicle
Your vehicle should not be modified. Modifica-
tion could affect its performance, safety or du-
rability, and may even violate governmental
regulations. In addition, damage or perfor-
mance problems resulting from modification
may not be covered under warranties.
! Mobile phones and driving
Do not use a hand-held phone while driving; it
may distract your attention from driving and
can lead to an accident. If you use a hand-held
phone, pull off the road and park in the safe
place before using your phone. In some States/
Provindes, only hands-free phones may legally
be used while driving.

dimmer to help prevent you from being blinded. For
this reason, use care not to cover the sensors with
stickers, or other similar items. Periodically wipe the
sensors clean using a piece of dry soft cotton cloth or
an applicator. "
Compass calibration
1. For optimum calibration, switch off all nonessential
electrical accessories (rear window defogger, heater/
air conditioning system, spotlight, etc.) and ensure all

switch is in the “ON” position.
3. Press and hold the left button for 3 seconds then re-
lease, and the compass will enter the calibration
mode. “CAL” and direction will be displayed.
4. Drive slowly in a circle until “CAL” disappears from
the display (about two or three circles). The compass
is now calibrated.
5. Further calibration may be necessary should out-
side. Influences cause the mirror to read inaccurately.
You will know that this has occurred if your compass
begins to read in only limited directions. Should you
encounter this situation, return to step one of the
above procedure and recalibrate the mirror. "
Compass zone adjustment
