1. TPE Floor & Trunk Mats: Typical Mistakes & Standard Installation Steps
Most Common Installation Mistakes
Fail to clean sand and debris under original carpet before laying mats, leading to sliding and abnormal driving noise;
Reverse front and rear mat directions, misalign pedal cutouts and footwell radian;
Ignore original car fixed buckles, fail to lock mat positioning holes, resulting in edge lifting during braking;
Force fold hard TPE mats in low temperature, forming permanent creases that cannot recover.
Correct Step-by-Step Operation
1. Use a vacuum cleaner to fully clean all dust, gravel and debris in footwell and trunk corners;
2. Take out mats and place them flat indoors at room temperature for 10 minutes to eliminate transportation folds;
3. Distinguish front driver / passenger and rear mats by pedal cutout shape, lay flat from the rear to front;
4. Align the reserved buckle holes with original car fixed posts, press down to lock positioning;
5. Push mat edges into the gap between carpet and plastic side panels to achieve full edge wrapping without gaps.
2. Custom Airbag-Compatible Seat Covers: Wrinkling & Displacement Fix Guide
Typical Mistakes
Skip pulling tight the bottom fixing straps, causing loose sliding and heavy wrinkles on seat surface;
Cover side airbag reserved openings, bring hidden safety risks in collision accidents;
Mix front and rear seat covers, inconsistent radian leads to incomplete wrapping;
Pull leather surface violently during installation, damage anti-fouling coating and surface texture.
Standard Installation Process
1. Adjust car seats to the farthest forward position to reserve sufficient operating space;
2. Slip the headrest cover over the headrest first, then put the main seat cover on from top to bottom;
3. Confirm the hollow airbag reserved window aligns exactly with the vehicle side airbag position, do not block;
4. Thread all bottom elastic straps under the seat, cross and buckle tightly to lock the cover firmly;
5. Smooth all surface wrinkles by gentle hand stretching, adjust side wrapping edges to fit seat radian completely.
3. Navigation & Instrument Tempered Screen Protectors: Bubble & Dust Mistakes Solution
Frequent Wrong Operations
Install in dusty outdoor environment, dust trapped under film causes permanent bubbles;
Touch the adhesive side of tempered glass with fingers, leave oil stains and poor adhesion;
Misalign camera and sensor cutouts, block vehicle light sensing and automatic wipers;
Peel the whole adhesive layer at one time, hard to reposition and produce large-area bubbles.
Bubble-Free Installation Steps
1. Park in a closed garage with little dust, turn off vehicle screen and wait for cooling;
2. Wipe screen surface thoroughly with matching alcohol cleaning cloth, then dry with microfiber dust-free cloth;
3. Only peel 1/3 of the bottom adhesive protective film first, align screen edges and camera cutouts precisely;
4. Slowly push the glass from center to four sides with the included squeegee to squeeze out all air bubbles;
5. Peel off the top surface protective film, wipe fingerprint oil stains on the glass surface once again.
4. No-Drill Exterior Mud Flaps & Door Sill Guards: Falling Off & Warping Causes
Main Installation Errors
Stick adhesive guards on dusty, wet or waxed car paint surface, tape loses adhesion quickly;
Skip alcohol surface cleaning step, residual wax reduces 3M tape viscosity;
Install in low temperature below 10°C, adhesive tape cannot fully activate and adhere firmly;
Wash the car within 24 hours after sticking, water inflow weakens adhesive performance.
Stable Long-Term Installation Tutorial
1. Clean target body panel with car wash liquid, dry completely and wipe with matching alcohol wipe to remove wax and grease;
2. Wait until the body surface reaches room temperature above 15°C before installation;
3. Peel a small section of backing tape, align accessory radian with wheel arch or door sill edge, press evenly;
4. Remove all remaining backing paper, apply uniform pressure to the whole accessory surface for 3 minutes;
5. Avoid high-pressure car washing and heavy rain flushing within 24 hours to allow tape to fully bond with paint.
General Post-Installation Inspection Checklist
Check TPE mats: no pedal blockage, all buckles locked, edges fully wrapped without lifting;
Check seat covers: airbag openings unobstructed, no loose sliding, surface smooth without heavy wrinkles;
Check screen films: zero bubbles, sensors and cameras fully exposed, touch screen sensitive normally;
Check exterior adhesive parts: no warping edges, full adhesion without gaps, no loose shake by hand pulling.
How to Solve Post-Installation Minor Problems
Small bubbles on screen film: lift the film edge slightly, squeeze out dust with dust sticker and re-squeegee;
Mat edge lifting: re-adjust mat position and re-lock original car buckles;
Adhesive guard edge warping: use a hair dryer to heat the edge slightly, press firmly for 2 minutes to restore adhesion;
Seat cover slight wrinkles: heat the surface with low-temperature hair dryer and smooth manually.
