HOOD
Revision: 2006 January2006 M35/M45
1. Check the clearance and the surface height between the hood and each part by visual and tactile feeling.
(Fitting standard dimension in the table below should be satisfied.)
* Unit: mm (in)
2. In case out of specification, adjust them according to the procedures shown below.
3. Remove the hood lock and adjust the height by rotating the
bumper rubber until the hood becomes 1 to1.5 mm (0.04 to
0.059 in) lower than the fender.
4. Temporarily tighten the hood lock, and position by engaging it with the hood striker. Check the lock and
striker for looseness and adjust the clearance and evenness by the striker to satisfy the specification.
5. Adjust A and B shown in the figure to the following value with hood's own weight by dropping it from
approx. 200 mm (7.87 in) height or the hood pressed lightly (approx. 29 N (3 kg)).
6. After adjustment tighten lock bolts to the specified torque.
1. Hood hinge 2. Hood lock assembly 3. Hood assembly
4. Hood top molding 5. Bumper fascia assembly 6. Headlamp

Hazard and Horn Reminder Function
When doors are locked or unlocked by Intelligent Key, Intelligent Key unit sends hazard and horn request sig-
nal to BCM via CAN communication line.
BCM flashes hazard warning lamps as a reminder and sends horn chirp signal to IPDM E/R. IPDM E/R
sounds horn as a reminder.
The hazard and horn reminder has a horn chirp mode (C mode) and a non-horn chirp mode (S mode).
Operating function of hazard and horn reminder
Hazard and horn reminder does not operate if any door switch is ON (any door is OPEN).
How to change hazard and horn reminder mode
With CONSULT-II
Hazard and horn reminder can be changed using “HORN WITH KEYLESS LOCK” and “HAZARD ANSWER
BACK” mode in “WORK SUPPORT”.Refer to BL-83, "
WORK SUPPORT" .
Without CONSULT-II
When LOCK and UNLOCK signals are sent from the Intelligent Key for more than 2 seconds at the same time,
the hazard and horn reminder mode is changed and hazard warning lamp flashes and horn sounds as follows:
Auto Door Lock Function
When all doors are locked, ignition switch is OFF (ignition switch is not pressed) and key switch is OFF (Intel-
ligent Key is not inserted in key slot), doors are unlocked with Intelligent Key button. When Intelligent Key unit
does not receive the following signals within 30 seconds, all doors are locked.
Door switch is ON (door is opened)
Door is locked
Ignition switch is ON
Key switch is ON (Intelligent Key is inserted in key slot)
Auto door lock mode can be changed by “AUTO RELOCK TIMER” mode in “WORK SUPPORT”. Refer to BL-
83, "WORK SUPPORT" .
Panic Alarm Function
When ignition switch is OFF (ignition switch is not pressed) and key switch is OFF (Intelligent Key is not
inserted in key slot), Intelligent Key unit receives PANIC ALARM signal from Intelligent Key.
Intelligent Key unit sends alarm request signal to BCM via CAN communication line.
BCM turns on and off headlamp intermittently and sends theft warning horn signal to IPDM E/R. Then, IPDM
E/R turns on and off horn intermittently.
The headlamp flashes and the horn sounds intermittently.
The alarm automatically turns off:
After 25 seconds
When Intelligent Key unit receives any signal from Intelligent Key
When door request switch is pressed (Intelligent Key is within the outside key antenna detection area)
Panic alarm function mode can be changed by “PANIC ALARM DELAY” mode in “WORK SUPPORT”. Refer to
BL-83, "
WORK SUPPORT" .
