No, you do not need to press the button on the handbrake lever when pulling it up to engage the parking brake. The button's sole function is to disengage the brake by releasing the internal ratchet mechanism. According to maintenance guidelines referenced by the RTA Dubai for vehicle safety inspections, the correct operation is to pull the lever up firmly and smoothly until you feel significant resistance, which indicates the rear wheels are secured. A common mistake in the UAE, especially with high-use vehicles like the Toyota Land Cruiser or fleet cars, is pulling the lever excessively tight, which can stretch the cable over time. The MOI UAE emphasizes regular checks of parking brake effectiveness as part of pre-summer vehicle preparation, crucial for preventing roll-aways on inclined parking common in areas like Jebel Ali or hilled communities. For a typical GCC-spec Toyota Hilux driven in mixed city and desert conditions, the handbrake cable might require adjustment every 2-3 years or 80,000 km due to this wear. The principle is simple: lift to park, press to lower.
- Mechanism: The button releases a pawl from a ratchet wheel; it is not for engagement.
- Correct Use: Pull firmly until secure, usually 3-5 clicks, without the button.
- Local Check: Test annually on a safe incline; the car should hold in place.
