Warning !
The jack is designed exclusively for jacking up the vehicle at the jack tubes built into either side of the
vehicle. To help avoid personal injury, use the jack only to lift the vehicle during a wheel change. Never get
beneath the vehicle while it is supported by the jack. Keep hands and feet away from the area under the lifted
vehicle. Always firmly set parking brake and block whee ls before raising vehicle with jack. Do not disengage
parking brake while the vehicle is raised. Be certain that the jack is always vertical when in use, especially on
hills. Always try to use the jack on level surface. Be sure that the jack arm is fully inserted in the jack tube.
Always lower the vehicle onto sufficient capacity jackstands before working under the vehicle.

Adjusting Headlamp Aim
(Halogen)





Correct headlamp adjustment is extremely important. To check and readjust a headlamp do the following:
• Horizontal aim will change and must be corrected as descri bed below, whenever a vertical adjustment is made.
• Low beam adjustments simultaneously aim the high beam and fog lamp.
• Vehicle should have a normal trunk load.

1 . Park vehicle on level surface approximately 6 inches (152 mm ) from a vertical test screen or wall. The centerline
of
the vehicle must be at a 90° angle to the test screen.
2 . Using a "T" square and a carpenter's level, align and ma rk avertical centerline (8) on the test screen using the
outer
reference point (low centerlines should be 47 1/4 inches (1198 mm).
3 . Move vehicle on the level surface 25 feet (7.6 m) straight back from the wall.
4 . Open hood, depress latch (1), and remove access cover (2) from the headlamp.
5 . Vertical headlamp aim (low beams on): Turn adjusting screw (3) (counterclockwise to adjust headlamp downward,
clockwise upward) until bubble in the level (4) is centered on the "0" mark. Graduations: 0.18° pitch.






6 . Horizontal headlamp aim (low beams on):
Turn adjusting screw (5) (Right fr ont headlamp: counterclockwise to adjust to the left, clockwise to the right; left
front headlamp: counterclockwise to adjust to the right, clockwise to the left.) until the headlamps (low beam)
illuminate the test screen as shown. The vertex of the angle formed in each beam image should align with the
vertical centerline (8) of each lamp. The left and right headlamps must be adjusted individually.

7 . The indicator (6) in the sight glass should align with the "0" mark after any horizontal adjustment. If it does not,
slide the "0" mark on the scale (7) until it a ligns with the indicator (6). Graduations: 0.38° pitch.
8 . Reinstall access cover(2).

vehicle must be at a 90° angle to the test screen.
2 . (low beams on) Using a "T" square and a carpenter's leve l, align and mark a vertical centerline (8) on the test
screen using the vertex of the angle formed in each beam image. As a check, the distance between centerlines
should be 47
1/4inches(1198mm).

3 . Mark a horizontal centerline (9) at a height of 221/2 inches (570 mm) on the test screen. It must be at a 90° angle
to the vertical centerline.

Battery

Warning !
Failure to follow these instructions can result in severe injury or death. Never lean over batteries while
connecting, you might get injured. Battery fluid contains sulfuric acid. Do not allow this fluid to come in
contact with eyes, skin or clothing. In case it does, immediately flush affected area with water and seek
medical help if necessary. A battery will also produ ce hydrogen gas, which is flammable and explosive.
Keep flames or sparks away from battery, avoid im proper connection of jumper cables, smoking etc..

Important !
Battery maintenance information:
The battery is located in the trunk under the trunk floor. The fluid level must be checked at every A and B service.
Always insure that the fluid level is at the specified maximum level and that only distilled water is used. Failure to
maintain proper fluid level may result in cell deterioration and possible battery rupture. The service life of the battery is
dependent on its condition of charge. The battery should alwa ys be kept sufficiently charged, in order to last an
optimum length of time.
Therefore, we strongly recommend that you have the battery charge checked frequently, and corrected if
necessary, especially if you use the vehicle less than approximately 200 miles (300 km) per month, mostly for
short distance trips, or if it is not used for long periods of time.
Only charge a battery with a battery charger after the battery has been disconnected from the vehicle electrical circuit.
Always disconnect the battery negative lead first and connect last. When removing and connecting the battery,
always make sure that all electrical consumers are off and the electronic key is in steering lock position 0. The battery
and its vent tube must always be securely installed when the car is in operation. While the engine is running the
battery terminal clamps must not be loosened or detached, otherwise the generator and other electronic components
would be damaged.

Note:
After reconnecting the battery al so resynchronize the Express feature of the power windows
(see Power Windows in Index).

Battery Recycling
Batteries contain materials that can harm the environment with improper disposal. Large 12 Volt storage batteries
contain lead. Recycling of batteries is the preferred method of disposal. Many states require sellers of batteries to
accept old batteries for recycling.

types of towing. The vehicle may be towed with all wheel s on the ground and the selector lever in position "N"
for distances up to 30 miles (50 km) and at a speed not to exceed 30 mph (50 km/h). The electronic key must
be in steering lock position 2. To positively avoid a possibility of damage to the transmission, however, we
recommend to disconnect the drive shaft at the rear axle drive flange on any towing beyond a short tow to a nearby
garage. Do not tow with sling-type equipment. Towing with sling-type equipment over bumpy roads will damage
radiator and supports. Use wheel lift, dolly, or flat bed equipment, with electronic key in steering lock turned to
position 0.


Warning !
With the engine not running, there is no power assistance for the braking and steering systems, in this case,
it is important to keep in mind that a considerably higher degree of effort is necessary to brake and steer
the vehicle.

position 2 and activate combination switch for left or right turn signal in usual manner - only the selected turn
signal will operate. Upon cancelling the turn signal, the hazard warning flasher will operate again.

Caution !
Vehicles with Acceleration Slip Regulation (ASR)
If the vehicle is towed with the front axle raised, the engi ne must be shut off (electronic key in steering lock position
0 or 1). Otherwise, the ASR will immediately be engaged and will apply the rear wheel brakes.


Caution !
Vehicles with Electronic Stability System (ESP)
If the vehicle is towed with the front axle raised, the engine must be shut off (electronic key in steering lock position
0 or 1). Otherwise, the ESP will immediately be engaged and will apply the rear wheel brakes.
